1 is a view showing the configuration of a lighting apparatus according to an embodiment of the present invention.

Referring to FIG. 1, the power source 100 may be a general indoor power source as an AC power source. The power supply may be a 220V 60Hz AC power supply. Light source 510-The light source 51n can be a lamp such as a lamp, a light bulb or a fluorescent lamp. In addition, the light sources 510 to 51n may be the same lamps or different lamps. In addition, the light source 510-the light source 51n may be a lamp having the same or different color temperature and / or color rendering index.

The controller 200 generates illumination control signals for controlling illumination of the light source 550-light source 51n. In this case, the illumination control signals may have a value at which the light sources 510 to 51n generate light with different illuminance.

The lighting power generator 300 inputs the AC power 100 and generates the lighting powers used as the operating power of the light sources 510 to 51n respectively corresponding to the AC power 100 by the lighting control signals. At this time, the illumination power is generated during a time or phase period set in one period (0 degrees-360 degrees) of the AC power source 100, wherein the generation time or phase interval of the illumination power is determined by the illumination control signal. The illumination power sources may generate AC power of a phase set as a lighting power by controlling the phase of the AC power 100 by a corresponding lighting control signal. In addition, the phase control value may be converted into time data and used. In the embodiment of the present invention, the illumination control signal is assumed to use phase control data. In addition, the controller 200 and the lighting power generating unit 300 may be configured integrally. That is, the controller 200 may be built in the lighting power generating unit 300, and may include a key input unit outside the lighting power generating unit 300 to control the lighting power. In the embodiment of the present invention described below, the controller 200 and the lighting power generating unit 300 will be described as a structure that is separated.

The lighting driver 400 converts the illumination powers generated by the illumination power generator 300 into a suitable voltage, current, and wavelength shape so that the corresponding light source 510-light source 51n lights or operates, respectively, to the light source 510-light source 51n. Apply each. The illumination driver 400 receives the illumination powers, selects illumination powers of the light sources 510-51n corresponding to the received illumination powers, respectively, and selects a voltage, a current, and a current for driving the corresponding light source. Convert to wavelength form. Accordingly, the lighting driver 400 selects lighting power corresponding to the light sources among the lighting powers, and generates the lighting driving power for driving the corresponding light source by using the selected lighting power as the control power. Accordingly, the lighting driver 400 may include a selection unit for selecting the illumination power of the corresponding light sources, and an illumination control unit for generating the illumination driving power of the light source corresponding to the selected illumination power to drive the light source. Here, the lighting driver 400 may be a ballast, and the lighting controller may be a dimming controller.

The lighting apparatus according to the embodiment of the present invention having the configuration as shown in FIG. 1 includes n light sources 510 to 51n, and generates and supplies independent lighting power sources to the light sources 510 to 51n, respectively. To this end, the illumination power generation unit 300 generates respective illumination power sources for driving the light sources 510 to 51n at different illuminance, and the illumination driver 400 is a power source suitable for driving the light sources 510 to 51n. The light sources 510 to 51n are driven by the conversion to.

In the embodiment of the present invention described below, the light sources 510 to 51n will be described on the assumption that an example includes a first light source and a second light source. In this case, it is assumed that the first light source and the second light source are light sources having different color temperatures and / or color rendering indexes as described above. In an embodiment of the present invention, the first light source has a warm color temperature. light), and the second light source is a cool tone light having a cool color temperature. The reason why the warm tone light source and the cool white light source are used as described above is that light is well mixed and thus natural light is easily realized. Here, the worm tone light source may have a color temperature between 2000 K and 3000 K, and the cool tone light source may have a color temperature between 600 K and 8000 K. In addition, since the warm white and cool white light sources use two light sources, the method of generating illumination power of the corresponding light sources is simpler than the method of using three color light sources of R, G, and B. Since the color temperature band is larger than the R, G, and B light sources, illumination of various color temperatures can be performed.

The illumination power generating unit 300 generates a first lighting power source and a second lighting power source determined by a user's setting, whereby the first light source and the second light source are connected to the first lighting power source and the second lighting power source. Thereby generating light, and the generated light can be addictively mixed to produce various types of light similar to natural light. The method for generating the first lighting power source and the second lighting power source may use a phase control method and a time control method.

Look at the phase control method. The AC power supply 100 has a signal waveform that is repeated at a period of 360 degrees (2π). And it is generated as a positive power source in the 0 degree to 180 degree interval (0-π: the first half cycle), and is generated as a negative power at 360 degrees (180 °-π: later half cycle). Accordingly, the first lighting power source may be generated by appropriately controlling the phase in the first half period of the AC power source 100 and the second lighting may be generated by controlling the phase properly in the second half period. For example, the phase of the AC power supply 100 is controlled to turn on in a section of 0 degrees to 135 degrees and to turn off in a section of 135 degrees to 180 degrees to generate a first lighting power source, turn on in a section of 180 degrees to 270 degrees, and then turn on at 270 degrees. The second lighting power source may be generated by turning off in a 360 degree section. In this case, the first lighting power source and the second lighting power source are generated at intervals of 0 degrees-135 degrees and 180 degrees-270 degrees in every cycle of the AC power supply 100. Therefore, if the phase of the first half cycle and the second half cycle of the AC power source 100 is properly controlled by the user's setting, the first and second lighting power sources capable of independently controlling the first and second light sources may be generated. The control of the light source may be controlled between 0 degrees and 180 degrees and 180 degrees and 360 degrees. However, since the lighting power is used as the operating power of each component at the rear end, it is preferable to perform phase control to generate the lighting power within an appropriate range. In the embodiment of the present invention, it is assumed that the illumination power is generated in the section of 0 degrees to 90 degrees and 180 degrees to 270 degrees.

Second, look at the time control method. The AC power supply 100 is an AC signal in which a cycle is repeated at a specific frequency. At this time, the frequency of the AC power source 100 has a frequency of about 60Hz to 50Hz. In the embodiment of the present invention, it is assumed that the AC power source 100 has a power frequency of 60 Hz. In this case, the period (0 degrees-360 degrees) of the AC power supply is 1.5 ms (1/60 Hz), and the half cycle of the AC power supply 100 is 0.75 ms. Accordingly, the AC power supply 100 becomes an AC signal repeated at 1.5 ms intervals, the first half cycle of the AC power supply is 0-0.75 ms, and the second half cycle is 0.75 ms-1.5 ms. Accordingly, if the time of the first half cycle and the second half cycle of the AC power source is properly controlled by the user's setting, the first and second lighting power sources capable of independently controlling the first and second light sources may be generated. Herein, the control of the light source can be controlled between 0-0.75 ms and 0.75 ms-1.5 ms. However, since the lighting power is used as the operating power of each component at the rear end, it is preferable to perform phase control to generate the lighting power within an appropriate range. In the embodiment of the present invention, it is assumed that the lighting power is generated in the interval of 0-0375 ms and 0.75 ms-1.125 ms every cycle.

In the following description, the method of generating the illumination power will be described on the assumption that the time control method is used. However, the phase control method can be used, and the same result can be obtained even when the phase control method is used.

2 is a diagram showing an example of the configuration of the above lighting apparatus according to an embodiment of the present invention.

Referring to FIG. 2, the first light source 510 and the second light source 550 may be light sources having different color temperatures and / or color rendering indexes as described above. In the following description, it is assumed that two light sources are described. Here, it is assumed that the first light source 510 is a worm tone light source and the second light source 550 is a cool tone light source. The warm tone light source may be a light source having a color temperature of 2000 K to 3000 K, and the cool tone light source may be a light source having a color temperature of 6000 K to 8000 K. In addition, the light sources 510 and 550 may be light sources with good mixing, and in this case, illumination of various color temperatures may be performed by controlling different illumination power sources of the light sources 510 and 550.

The first and second lighting power generation units 310 and 350 generate first and second lighting power sources for driving the light sources 510 and 550 for a predetermined time period, respectively, for the AC power. Here, the period may be one period (0 degrees to 360 degrees) of the AC power. In addition, it is assumed that the first lighting power source and the second lighting power source are generated for a predetermined time at different start positions, respectively. For example, the first lighting power is generated for a set time in the first half period (0 degrees -180 degrees) of the AC power, and the second lighting power is set in the second half period (180 degrees-360) of the AC power. Can occur over time. The generation time of the first and second lighting power sources may be set to the same time and may be set to different times.

The first and second lighting drivers 410 and 450 select corresponding first and second lighting power sources, respectively, and select voltage, current, and / or wavelengths of the selected first and second lighting power sources from the light source 510 and After converting to a form suitable for 550, they are applied to the corresponding first and second light sources 510 and 550, respectively. In this case, the first and second lighting drivers 410 and 450 smooth and divide the corresponding lighting power into a control voltage in the form of DC voltage, and oscillate internally according to the magnitude of the converted control voltage to drive the corresponding light source. It generates a lighting driving power for. The rectifier 490 rectifies the first lighting power and the second lighting power and supplies the rectified power to the operating power of the first and second lighting drivers 410 and 450.

The key input unit 230 generates a key command for lighting on / off of the light sources 510 and 550 and a key command for controlling an illumination time of the light sources 510 and 550. The control unit 210 controls the first and second lighting control signals for controlling the time for generating the lighting power in the first and second lighting power generating units 310 and 350 and the illumination of the light sources 510 and 550 according to the key command of the key input unit 230. Generates a control signal for on / off. The memory 200 stores the lighting control program and the data generated during the lighting control program according to the embodiment of the present invention.

2 illustrates an example of using two light sources of light sources 510 and 550 as described above, but may be configured using three or more light sources as necessary. In this case, when three or more light sources are used, the lighting power generator 300 and the lighting driver 400 may further include a configuration for generating the lighting power and the lighting driving power according to the corresponding number of light sources.

Looking at the operation of the lighting device having the configuration as described above, the first light source 510 and the second light source 550 is a lamp, as described above may be a lamp having the same color temperature or (and) color rendering index. It may be a lamp having a different color temperature or (and) color rendering index. In the embodiment of the present invention, it is assumed that the first light source 510 and the second light source 550 are lamps having different color temperatures (or color rendering index).

Looking at the definition of the color temperature, when the object is shining with visible light, if the color looks like a color that the black body of a certain temperature radiates, it is assumed that the temperature of the black body and the temperature of the object is equal to the color temperature of the object It is called. That is, the color temperature of the object is represented by the temperature (absolute temperature K) of the black body of the same color light. For example, the light of the bulb is 2,800K, the fluorescent light is 4,500 ~ 6,500K, the noon sun light is 5,400K, the cloudy daylight is 6500 ~ 7000K, and the clear blue sky light is 122,000 ~ 18,000K. It has a color temperature of about. In addition, the definition of the color rendering index shows that red and yellow colors are emphasized by inclining toward the red of the spectrum under incandescent lamps, and blue systems are clearly visible under fluorescent lamps. Is called the color rendering index (Ra). The color rendering index 100 gives a pleasant feeling with lighting faithful to natural light.

The embodiment of the present invention proposes a method of artificially making a change in sunlight so that people living indoors feel comfortable. The sunlight is composed of warm colors (for example, red, yellow, magenta, etc.) and cool tones (for example, green, cyan, blue, etc.). In an embodiment of the present invention, the first light source 510 is used as a warm color lamp, the second light source 520 is used as a light lamp, and these two light sources 510 and 520 are addictively mixed to add light to the natural light. Create the lighting of the light you want. That is, by using a mixture of cold and warm colors as described above, it is possible to express various types of color temperature, and when applied to this, it is possible to realize light of various conditions expressed in natural light by artificial lighting.

The user sets a desired lighting condition of the light sources 510 and 550 through the key input unit 230. The lighting condition may be a condition for setting driving conditions of the light sources 510 and 520. In this case, the key input unit 240 may include a plurality of keys for setting lighting conditions, where the lighting conditions enable the light sources 510 and 550 to be set for each of the maximum and minimum illumination levels. The memory 220 may store time information for supplying illumination power to the light sources 510 and 550 according to the illumination conditions. Then, the controller 210 analyzes the key data generated by the key input unit 240, and then, in the memory 220, the first lighting power source corresponding to the lighting control data of the first light source 510 and the second light source 550 according to the lighting condition. The generator 310 and the second lighting power generator 310 is applied.

Then, the first lighting power generator 310 and the second lighting power generator 350 generate the first lighting power and the second lighting power according to the lighting control data. The illumination power generators 310 and 350 generate illumination powers according to the illumination control data in one cycle of the AC power input 100. At this time, the AC power source 100 may be an indoor power source as described above, and may be a power source having a frequency of 60 Hz and a peak voltage of 220 V. The AC power source 100 is a power source in which an AC waveform having a period of 360 degrees that is zero-crossed at 0 degrees and 180 degrees is repeated, and the section of 0 degrees to 180 degrees is a section having a positive power source (hereinafter, the first half period). And a section of 180 degrees to 360 degrees is a section having a negative power supply (hereinafter referred to as a late period). In the exemplary embodiment of the present invention, a first illumination power source for driving the first light source 510 is generated during the first half period of the AC power source and a second illumination power source for driving the second light source 550 during the late period. It is assumed that this occurs. In this case, the first lighting power generation unit 310 generates a first lighting power for driving the first light source 510 for a time set by the user in the first half period, the second lighting power generation unit 350 is a late period section Generates a second lighting power source for driving the second light source 550 for a time set by the user. In this case, the time for generating the first and second lighting power may be generated at the same time by the user's setting, and may be generated at different times.

The first and second lighting power generating units 310 and 350 should be provided with a power generating element for generating lighting power in a set section. As an element for generating the illumination power using the AC power source 100, a silicon controlled rectifier (SCR), a triac, or the like may be used. The silicon controlled rectifier is composed of three terminals: an anode, a cathode, and a gate. When a signal is applied to the gate, a reverse current is applied to the main circuit or a current is maintained without supplying a continuous gate current. It is an AC power control device that maintains the energized state until it falls below the holding current. The triac is a bidirectional element composed of two silicon controlled rectifiers (SCRs), and may control a power source in which a positive power source and a negative power source are alternately changed, such as an alternating current. When the triac is used as the configuration for generating the illumination power, the first and second lighting power generators 310 and 350 may be configured as one element, and when the silicon controlled rectifier is used, FIG. 2. It can be configured using two silicon controlled rectifiers as shown. In the embodiment of the present invention, it is assumed that the silicon controlled rectifier is used.

3A and 3B are views showing the configuration of the illumination power generators 310 and 350 according to the embodiment of the present invention, showing an example in the case of using a silicon controlled rectifier. 3A illustrates a configuration example in which the first lighting power generating unit 310 and the second lighting power generating unit 350 include a zero crossing detection unit and a phase controller, respectively, and FIG. 3B illustrates the first lighting power generation unit. An example in which the unit 310 and the second lighting power generation unit 350 share a zero crossing detection unit and a phase controller is shown. 4 is a diagram illustrating timing of generating illumination power in the illumination power generation units 310 and 350.

3A and 4, first, phase controllers 315 and 355 set phase control values corresponding to first and second lighting control signals respectively output from the controller 210. At this time, the lighting control data output from the controller 210 is determined by the user's setting, and may be set to the same phase or different phases. The silicon controlled rectifier 311 generating the first lighting power source has an anode terminal connected to the AC power source 100, a cathode terminal connected to the first light driver 410, and a gate terminal connected to the phase controller 315. In the silicon controlled rectifier 351 generating the second lighting power source, a cathode terminal is connected to the AC power source 100, an anode terminal is connected to the second lighting driver 410, and a gate terminal is connected to the phase controller 355. In the following description, the silicon controlled rectifier 311 is called a forward connection and the silicon controller 351 is called a reverse connection. At this time, the silicon-controlled rectifier 311 generates a positive power (phase wave in FIG. 4) as the first lighting power during the phase control period set in the first period in which the positive power of the AC power is generated as the first lighting power generating element. The control rectifier 351 generates the negative power (low wave in FIG. 4) as the second lighting power during the phase control period set in the second period in which the negative power of the AC power is generated as the second lighting power generating element.

First, the zero crossing detection unit 313 inspects the AC power source 100 and generates a zero crossing detection signal as shown in 4b at the time when zero crossing is changed from a negative power source to a positive power source. Then, the phase controller 315 is driven to apply a control signal for turning off the silicon controlled rectifier 311 to the gate terminal of the silicon controlled rectifier 311 as shown in 4c. Then, the silicon controlled rectifier 311 is switched off to block generation of the AC power supply 100 as in 4d. When the phase set in the phase controller 315 is finished, the control signal is generated on the gate terminal as shown in 4c. Then, the silicon controlled rectifier 311 is turned on to transmit the AC power supply 100 to the lighting driver 400. Therefore, the first lighting power generation unit 310 is switched off at the zero crossing time when the AC power source 100 is changed to a positive power source to block the supply of the AC power source for the set phase as shown in 4d, and then The AC power is transmitted to the lighting driver 400 to generate the lighting power of the first light source 510. At this time, the phase value for generating the first lighting power is generated for a time set in the first half period (both power generation period) of one cycle of the AC power.

Secondly, the zero crossing detection unit 353 examines the AC power supply 100 and generates a zero crossing detection signal as shown in 4e at the time when zero crossing is changed from a negative power supply to a positive power supply. Then, the phase controller 355 is driven to apply a control signal for turning off the silicon controlled rectifier 311 to the gate terminal of the silicon controlled rectifier 311 as shown in 4f. Then, the silicon controlled rectifier 351 is switched off to cut off the AC power supply 100 such as 4g. When the phase value set in the phase controller 315 is reached, an ON control signal is generated at the gate terminal, and the silicon controlled rectifier 311 is turned on to transmit the AC power supply 100 to the lighting driver 400. Therefore, the first lighting power generation unit 310 is switched at the zero crossing time when the AC power source 100 is changed to a positive power source, and cut off the supply of the AC power source for a time set as 4g, and the set phase When the value reaches a value, the AC power is turned on and output to generate the lighting power of the second light source 550. At this time, the time for generating the second lighting power is generated for a time set in the second half period (negative power generation period) of one cycle of the AC power.

Therefore, by controlling the time for generating the 4b and 4f and the first lighting power source and the second lighting power source of FIG. 4, it is possible to vary the size of the illumination power supplied to the first light source 510 and the second light source 550, Illumination brightness of the first light source 510 and the second light source 550 may be varied. At this time, the generation time of the first lighting power source and the second lighting power source can be controlled independently, and thus, the lighting power applied to the first light source 510 and the second light source 550 can be supplied in different sizes. Lighting with various illuminance can be achieved.

In FIG. 3A, the zero crossing detection units 313 and 353 may be implemented using a comparator. That is, when the zero crossing detection unit is configured as a comparator, the reference power source may be used as the ground power source OV. In this case, the zero crossing detection unit generates signals of different logic in the positive power section and the negative power section of the AC power supply 100, and the section is changed from the negative power source to the positive power source and the section is changed from the positive power source to the negative power source (that is, zerocrossing). In the section in which the logic occurs). Therefore, the zero crossing detection unit may be configured as shown in FIG. 3A, and one zero crossing detection unit may be used. In addition, the phase controllers 315 and 355 store the phase value set by the user to determine the illumination power generation interval.

The phase controllers 315 and 355 may be implemented as processors. When the phase controllers 315 and 355 are implemented by a processor, a memory may be provided to store time data for generating the illumination power by an illumination control signal. In this case, the controller 200 may operate as a remote controller. When the lighting control signal is generated by the controller 200, the processor sets a phase value for generating the first lighting power source and the second lighting power source, and zero crossing of the AC power source 100 occurs in the zero crossing detection unit. Is generated, the phase control signal for generating a corresponding illumination power source.

3B is a diagram showing the configuration of an illumination power generation unit using one zero crossing detection unit and a processor as described above.

Referring to FIG. 3B, the processor 320 receives an illumination control signal from the controller 200 and analyzes the received illumination control signal to determine a phase for generating the first lighting power and a phase value for generating the second lighting power. And set the determined phase value. The zero crossing detection unit 325 detects the first zero crossing time point when the AC power source 100 is transitioned from the negative power source to the positive power source and the second crossing time point when the AC power source is transitioned from the positive power source to the negative power source, and notifies the processor 320. In this case, logics of the first and second zero crossing detection signals generated by the zero crossing detection unit 325 may be generated by different logics, and thus, the processor 320 may detect the first and second zero crossings. First, when the first zero crossing is detected, the processor 320 turns off the silicon controlled rectifier 311 during the set first phase control period to generate the first lighting power. When the second zero crossing is detected, the processor 320 is configured to detect the second zero crossing. The silicon controlled rectifier 351 is turned off during the set second phase control period to generate a second lighting power source.

Here, the silicon controlled rectifier 311 and the silicon controlled rectifier 351 are connected between the AC power source 100 and the lighting drivers 410 and 450 in the same state as in FIG. 3A. The silicon controlled rectifiers 311 and 351 are triac configurations. Therefore, the silicon controlled rectifiers 311 and 351 may be replaced with a triac.

The diode may be connected to an output terminal of the power generator 300 and an anode terminal is connected to an input terminal of the second lighting controller 415. Then, when the illumination power generation unit 300 generates the illumination power as shown in 4h of FIG. 4, the selection unit 411 is turned on in a section that is a positive power (upper wave in the drawing) generated in the first half period of the AC power source 100.

To generate a lighting drive power source (which can be a frequency here). At this time, the illumination driving power is determined by the size of the illumination power (that is, the power generated by the phase (or time) control of the AC power). The first and second lighting control units 415 and 455 adjust the illumination of the light sources 510 and 550 according to the first and second lighting power sources that are independently changed by a user's setting. Accordingly, the lighting controllers 415 and 455 have a dimming control function that independently adjusts the illumination of the light sources 510 and 550 according to a user's setting.

During the generation period (set by the second phase control value), the AC power source 100 is turned on to generate the second lighting power source.

As described above, the illumination power generation unit 300 turns on / off the AC power source 100 according to a phase control section set at every cycle of the AC power source 100 and generates the lighting power as the illumination power of the first and second light sources 510 and 550. . At this time, as described above, the first lighting power is generated for the time set in the first half period of the AC power source 100, and the second lighting power is generated for the time set in the second half period of the AC power source 100. Here, the lighting power method has been described using a phase control method as an example, but when the time control method is set as described above, the lighting power may be generated by controlling the time of the AC power supply 100.

When the lighting off command is generated by the user, the power generation unit 300 detects this in step 651 and stops the lighting power generation procedure in step 653.

As described above, FIG. 7 illustrates an operation procedure when the lighting power generator 300 includes the controller 200. However, when the illumination power generation unit 300 and the controller 200 are configured independently, the control unit 200 performs steps 611 to 621 to calculate the time (or phase) of generating the illumination power, and the illumination power generation unit You can use the 300 delivery method. In this case, the control unit 200 generates time control (phase control) data of the illumination power set by the user as an illumination control signal, the illumination power generation unit 300 stores the illumination control signal, and the illumination on request The AC power source 100 may be controlled to be generated as an illumination power source according to the stored lighting control signal. Accordingly, in the case of the lighting power generating unit 300 having the configuration as shown in FIG. 3B, the same procedure as in FIG. 7 may be performed, and in the case of the lighting power generating unit 300 having the configuration as shown in FIGS. 3A and 3B, the After storing the lighting control signal transmitted from the controller 200, the lighting power can be performed by performing steps 631 to 639 when the lighting-on is requested.
