According to the current installation standards of street lamps, if the streetlight is installed at a height of 10m from the ground, the side illuminance generated at a point 10m to the left and right from the spot on the ground where the streetlight is installed should emit up to 20Lux. However, in the case of a street lamp composed of LEDs, side lighting and visibility are inferior due to the characteristic of straightness in emitting light from the LED. In the case of constructing an LED street lamp in the form of a filament type streetlight, There is a problem that light is weak and the illuminance of the street light installation standard is not satisfied. As prior art patents related thereto, Korean Registered Utility Model No. 20-0439441 and Korean Patent Registration No. 10-896768 are known.

However, according to the above-mentioned prior patent, the side light of the LED lamp, which is the intensity of weak light, is irradiated through the reflection plate and can not exhibit an effect exceeding expectations. The bottom surface is formed in a shape raised from the rear end toward the front end, The irradiation angle can not be adjusted according to the situation of each road. In addition, in order to satisfy the streetlight installation standard, a large number of LED elements must be integrated on the PCB of the LED module, which causes a significant amount of heat to be generated, shortening the life of the LED module.

In addition, according to the present invention, the sensing means 40 installed in the inside of the illumination lamp 20 detects the temperature, the irradiation amount, the irradiation angle, and the surroundings of the illumination lamp 20. The sensing means 40 is installed in the power supply unit 25 of the casing 21 as shown in FIG. 2, and the sensing means is operated as an electrical signal to the control means described later. Here, the sensing means means the total combination of the individual sensors corresponding to the respective physical quantities by sensing the control condition corresponding to the illumination lamp 20, that is, the temperature, irradiation amount, The present invention is not limited to such a structure.

The sensing means 40 includes a temperature sensor 41 for detecting the temperature in the power supply unit 25, an illuminance sensor 43 for detecting the amount of illumination of the illumination lamp 20, An air pressure sensor 45 for detecting the surrounding environment of the illumination lamp 20 and an acceleration sensor 47 for detecting the illumination angle of the illumination lamp 20. The sensing means 40 senses the control conditions corresponding to the illumination lamp 20 of the illumination lamp 20, that is, the temperature and the irradiation amount of the illumination lamp 20, the irradiation angle, and the surroundings as shown in FIG. The ambient temperature sensor 41 senses the temperature in the power supply unit 25 of the illumination lamp 20 and the illuminance sensor 43 senses the irradiation amount of the illumination lamp 20, And the acceleration sensor 47 detects a change in the angle of incidence of the illumination light 20, that is, the inclination angle of the illumination light 20. Each of these sensors 41, 43, 45 and 47 operates in cooperation with the control means.

Further, according to the present invention, the control means corresponding to the input of the sensing means (40) changes the dimming condition of the LED module (30). The control means refers to a system board installed in the power supply unit 25 of the casing 21 to receive the system board. The system board is based on a microcomputer circuit having a CPU, a memory, and an input / output interface. The set algorithm for control is stored and updated in memory. The input / output interface is connected to each of the sensors 41, 43, 45, and 47. These system boards generate PWM (Pulse Width Modulation) and PDM (Pulse Duration Modulation) outputs by using internal modules such as a module or timer / counter built in CPU and output after process processing.

On the other hand, basically, by using Timer / Counter and setting the Timer / Counter constant value, the operation frequency (several tens Hz to several Khz) and the duty ratio (ON / OFF output) are determined and the pulse is output controlled. Here, the operating frequency can be adjusted to several hundreds to several Khz according to the value of A_DATA (a certain value) declared as a constant, and the duty ratio adjustment range is about 1% to 98% Analog output (0 ~ 10V, 1 ~ 10V) is generated through LED, and LED lighting intensity can be controlled according to the value of analog output at LED lighting power input.

In the detailed configuration of the present invention, the control means uses the signals of the sensors 41, 43, 45 and 47 to set the brightness of the illumination lamp to 90 to 97%, the atmospheric pressure to 900 to 1000 mbar (49) for dimming the LED module (30) with the brightness of the illumination lamp (40 to 60%) when the brightness of the illumination lamp is 90 to 100% when the angle of the illumination lamp is in a range of 3 to 6 lux and the inclination angle of the illumination lamp is changed by 10 or more . The control means controls the temperature of the power source 25 of the illumination lamp 20 through the temperature sensor 41 and controls the illumination light 20 and detects the change of the inclination angle of the illumination lamp 20 through the acceleration sensor 47. The acceleration sensor 47 detects the change of the inclination angle of the illumination lamp 20 through the air pressure sensor 45, That is, the temperature sensor 41 is dimming according to the set temperature, the illuminance sensor 43 is dimming according to the surrounding environment, the air pressure sensor 45 is dimming according to the weather change, and the acceleration sensor 47 is dimming according to the inclination angle Respectively.

7, when the temperature of the power source 25 of the illumination lamp 20 is gradually increased as the temperature of the casing 21 is lowered by the time the heat is released per hour, When the temperature of the power source unit 29 rises to 60 ° C or more due to the above reason, the brightness of the illumination lamp 20 is 90% to 97%, thereby maintaining the temperature of the power source unit 29 constant, .

Since the inclination angle is measured by the always-used acceleration sensor 47, the illumination lamp 20 is operated when it is operated for a long time and the angle of inclination is changed, such as twist due to the surrounding environment (wind speed) When the horizontal angle deviation roll angle (± 10 ° or more) occurs, the brightness of the illumination lamp 20 is dumped by 40 to 50%. Of course, the illumination light 20 is also checked through the acceleration sensor 47 when installing. In addition, when the lighting lamp 20 is operated for a long time and twisted due to the surrounding environment (wind speed), the product is bent and the inclination angle is changed, when the lamppost and the arm are inclined (Roll angle is ± 10 ° or more and Pitch angle is ± 20 ° or more) , The brightness of the illumination lamp 20 is 50 to 60%, and the illumination lamp 20 is checked or repaired or changed.

The illuminance sensor 43 and the air pressure sensor 45 operate in accordance with the ambient environment of the illuminating lamp 20 and the weather change. When the output of the air pressure sensor 45 is 900-1000 mbar (clear) The brightness of the illumination lamp 20 is 90% to 95%, and when the output value of the illuminance sensor 43 is 4 to 5 lux or less, the brightness of the illumination lamp 20 is 100% dimming off. When the output of the air pressure sensor 45 is 900 mbar or less and the output value of the illuminance sensor 43 is 5 lux or more, the brightness of the illumination lamp 20 is 90 to 95%, and the output value of the illuminance sensor 43 is 3 to 4 When it is lux or less, the brightness of the illumination lamp 20 is 100% dimming off.

In response to the measured values of the respective sensors 41, 43, 45 and 47, the controller 49 controls the output by finely adjusting the frequency change (1,000 Hz ± 30%) or the duty ratio in the PWM output When the DAC output is changed (9 to 10 V), the dimming operation is performed according to the input DAC value. Of course, the final decision on this correction should be made by the main control unit in the control room or control room (not shown) of each municipality.

Furthermore, a central control tower can be connected to the system board of the illumination lamp 20 according to the present invention by wired / wireless connection, and a control module can be installed on the system board. Do. The communication module may be configured to exchange information through a portable terminal such as a user's desktop or notebook PC, a mobile device such as a smart phone, or a PDA. In other words, the dimming condition of the illumination lamp 20 can be remotely checked to recover or control the error.

As described above, according to the present invention, the LED lighting apparatus can reduce the manufacturing cost as well as improve the assembling and productivity based on the lightweight structure in terms of manufacturing and use, and significantly improve the heat dissipation property in an economical manner, It is possible to prevent safety accidents while improving visibility and illuminance by automatically changing according to the environmental conditions, and it is possible to freely install various types of LED lighting fixtures, and thus it is easy to implement various types and types of LED lighting fixtures One structure can be provided.
