LED sunlight and LED sunlight luminaire {LED sunlight and LED luminaire}

The present invention relates to an LED sunlight lamp using a light emitting diode and a lighting fixture using the same. More specifically, it relates to an LED sunlight lamp and a luminaire for emitting light having a spectrum similar to that of sunlight by using a plurality of LED chips in lighting using LEDs.

A light source using a light emitting diode (LED) chip has been rapidly developed due to the degree of freedom in designing various lightings in addition to advantages such as power consumption and durability.

After the completion of the initial three primary color (R, G, B) LED chip invention, research on light sources using this has been actively conducted, and efficient white light is realized by combining three primary color LEDs, and phosphors are processed in primary color LEDs or short-wavelength LEDs. Therefore, various light sources such as incandescent lamps have been developed. Illumination of white light using an LED chip is advantageous in terms of brightness efficiency, and illumination of an incandescent light bulb is advantageous to human health, so it is used in an appropriate combination. However, the most beneficial light for the human body is known as sunlight (sunlight), and lighting closest to sunlight is required in environments where people mainly live indoors or in basements where sunlight is poor. In order to bring sunlight into a space such as a basement where sunlight does not reach, a method of bringing sunlight from the outside into the room through a reflector using a reflector, a conduit, etc. is used, but it is uneconomical compared to its efficiency and installation cost.

Regarding a lighting module having a spectrum close to sunlight using an LED chip, Korean Patent No. 10-1268369 (Registration Date: May 22, 2013) discloses a natural light LED module and an invention of a lighting device using the same.

The patented invention provides a natural light LED module providing a spectrum distribution similar to sunlight and a lighting device using the same, comprising: a plurality of lead frames formed on a printed circuit board; a plurality of first LEDs installed on the lead frame to emit blue-violet light; a second LED installed on the lead frame to emit red light; And a blue phosphor, a green phosphor, a red phosphor, and a yellow phosphor mixed at an arbitrary weight ratio (Wt%) and a phosphor mixture portion applied on the first LED, and a third LED emitting cyan It is an invention that can provide a natural light LED module with a high color rendering index by providing a similar spectrum distribution to sunlight that can be further included.

In the patented invention, a natural light LED having a first LED (blue-violet) and a second LED (red) and having an RGB phosphor coated on the first LED is a first LED coated with a phosphor that exhibits brightness efficiency ( blue-violet) and the second LED (red) that reinforces the function to realize natural light, since the first LED (red) has a peak wavelength, it appears as one signal for every 10 nm wavelength, so a large number of first LEDs are adopted. In this case, there is a problem that the brightness efficiency as lighting is lowered. In addition, when the third LED (cyan) is added, the number of red LEDs can be reduced, but there is a problem in reducing the number to realize natural light.

In addition, for example, by configuring an LED module with 2 first LEDs (cyan), 1 second LED (red), and 4 third LEDs (cyan) as a set, each module has a PCB substrate and 4 LEDs. When a surface light source is formed by using a lead frame, there is a problem in that the structure becomes complicated and power consumption increases according to the number of PCB boards corresponding to the number of modules, the lead frame, etc., corresponding to the number of modules. Even when implementing a lighting fixture, there is a problem in that its size increases because several LED modules must be used.

Therefore, a sunlight lamp capable of emitting a spectrum similar to sunlight is implemented using an LED chip, but the configuration includes a red light emitting LED light source having a peak wavelength as a minimum, and when implemented as a surface light source, the structure is simple and power It is desired to develop an LED sunlight lamp that does not consume much and can be formed in a small size with a single structure even when applied to a light bulb type.

Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 is a schematic conceptual diagram for explaining an embodiment of an LED headlight of the present invention. As shown in FIG. 1, the LED sunlight lamp 10 of the present invention is a plurality of first LED light sources 210 having a color temperature (degree of Kelvin) of 5000K to 6500K when the RGB phosphor is applied to a purple light emitting LED chip to emit light. class; a plurality of second LED light sources 220 having a color temperature of 2500K to 3000K when RGB phosphor is applied to a purple light emitting LED chip to emit light; It includes a plurality of third LED light sources 300 made of red light emitting LED chips, and the number of the first LED light sources 210 is 50% to 80% in the case of the same power, and the number of the second LED light sources 220 is 5 % to 10%, and the number of the third LED light sources 300 is selected and arranged in the range of 15% to 40%.

The first LED light source 210 applies red (R) phosphor, green (G) phosphor, and blue (B) phosphor to the purple light emitting LED chip, and the color temperature is 5000K to 6500K when the purple light emitting LED chip emits light. , preferably 6500K, and is configured to emit light in a state corresponding to the atmosphere of the sky on a clear day (day white) with a white-series tint with a slight blue tint.

In addition, the second LED light source 220 applies red (R) phosphor, green (G) phosphor, and blue (B) phosphor to the purple light emitting LED chip, but when the purple light emitting LED chip emits light, the color temperature is 2500K~ 3000K, preferably 2700K, and is configured to emit light at sunrise and sunset with a warm white tint with a slight red tint.

The red light emitting LED light source 300 is configured to emit red light having a peak wavelength of 660 nm to 780 nm. It is not limited thereto, and an LED light source emitting red light or near-infrared rays having a peak wavelength of 660 nm to 780 nm may also be adopted. The spectrum of the sun shows peak values at 670 nm, 700 nm, 750 nm, and 780 nm in red and near-infrared rays, so it is important to arrange peak value LEDs the same as the sun.

The first LED light source 210 is configured to maintain 50% to 80% of the number of light sources disposed in the case of the same power in the total number of LED light sources such as the hat of the present invention in order to maintain the efficiency as bright lighting , In the second LED light source 220, the color temperature of day white or cool white of the first LED light source 210 is changed to warm white, and the efficiency of brightness is lowered, but delayed by sunlight. For the function, the number of light sources disposed is configured to maintain 5% to 10% of the total number of LED light sources of the hat of the present invention, and the third LED light source 300 is the first LED light source 210 and In order to emit a spectrum similar to sunlight by adding red light to the light that is delayed from the second LED light source 220 to the sunlight lamp, the number of light sources arranged is 15% of the total number of LED light sources of the sunlight lamp of the present invention. It can be configured to hold ~40%. If the powers are different, the ratio can be adjusted with the sum of each LED power instead of the number of light sources.

In addition, as another embodiment of the present invention, when the power is the same, the number of the first LED light sources is 50% to 85%, the number of the second LED light sources is 0% to 10%, and the number of the third LED light sources is It can be configured to hold between 15% and 40%.

For example, in the case of using an LED chip with an output of 40W and an output of 1W, the sunlight lamp, which is an embodiment of the present invention, has 24 (60%) first LED light sources 210 having a color temperature of 6500K as shown in FIG. ), 4 second LED light sources 220 having a color temperature of 2700K (10%), and 12 third LED light sources 300 having a peak wavelength of 660 nm to 780 nm (30%) are arranged, similar to the spectrum of sunlight. LED sunlight with a spectrum can be implemented.

Figure 2 is a schematic configuration diagram of an LED chip whose color temperature is adjusted, which is a main part of an embodiment of an LED sunlight lamp of the present invention.

As shown in FIG. 2, the color temperature-adjusted LED chip of the present invention includes a purple light emitting LED chip 200 and an RGB phosphor coating layer 20 coating the purple light emitting LED chip 200. It is a composition that In addition, it may be configured to include a transparent resin 30 covering the purple light emitting LED chip 200 and the RGB phosphor coating layer 20 .

It is currently known that the purple light emitting LED chip 200 is manufactured in various ways. For example, InGaN, which has an active layer and is manufactured to emit purple light having a peak wavelength of 400 nm to 408 nm, may be used. However, the purple light emitting LED chip 200 used in the embodiment of the present invention is not limited thereto.

The RGB phosphor coating layer 20 is formed by mixing red (R) phosphor, green (G) phosphor, and blue (B) phosphor materials with epoxy or the like, applying them to the purple light LED chip 200 and drying them.

Red (R) phosphor, green (G) phosphor, and blue (B) phosphor materials, which are the RGB phosphor materials, have been developed and known in various ways.

In the present invention, as the RGB phosphor material, red (R) phosphor is K(WO ₄ ):Eu, Sm, green (G) phosphor (BaSr) ₂ SiO ₄ :Eu, blue (B) phosphor (SrMg) ₁₀ (PO ₄ ) ₆ Cl ₂ :Eu can be used. However, the RGB phosphor material used in the embodiment of the present invention is not limited thereto.

While the purple light emitted from the purple light emitting LED chip 200 as an excitation light source passes through the RGB phosphor coating layer 20, the purple light is changed into light of a different color (color temperature) and emitted. In this case, it is possible to adjust the color temperature that changes when the purple light passes through the RGB phosphor coating layer 20 . The color temperature may be adjusted by adjusting the mass ratio of the RGB phosphor material to the mass of the sample in which the epoxy and the RGB phosphor material are mixed. When the mass ratio of the RGB phosphor material is low (eg, 38% or less), the color temperature of the purple light transmitted through the RGB phosphor coating layer 20 changes to close to white, and when the mass ratio of the RGB phosphor material is increased, the RGB phosphor coating layer ( 20), the color temperature is changed to yellowish green as the light transmission decreases.

Therefore, in the first LED light source 210 of the present invention, the mass ratio of the RGB phosphor materials in the RGB phosphor coating layer 20 of the purple light emitting LED chip 200 is low, while the purple light transmitted through the coating layer is reduced. The color temperature is adjusted to be 5000K to 6500K, preferably 6500K, and the second LED light source 220 is the mass ratio of the RGB phosphor material in the RGB phosphor coating layer 20 of the purple light emitting LED chip 200. It can be configured by adjusting the color temperature of purple light transmitted through the coating layer to be 2500K to 3000K, preferably 2700K, while forming high.

Figure 3 is an embodiment of the LED sunlight lamp of the present invention and the wavelength of sunlight (natural light) - a graph showing the relationship between relative intensity.

As shown in FIG. 3, the relative intensity of each wavelength of color temperature is shown, and sunlight (natural light) (blue dotted line) shows relative intensity between 450 nm and 500 nm wavelength in the range of visible light wavelengths (380 nm to 780 nm). is the largest, and the relative intensity gradually decreases toward the latter wavelength, showing repetitive peak characteristics between 660 nm and 780 nm (670 nm, 700 nm, 750 nm, 780 nm, etc.).

The first LED light source 210 (purple solid line) of the present invention, which is adjusted to a color temperature of 6500K by applying RGB phosphors to the LED chip 200 emitting purple light having a peak wavelength of 400 nm to 408 nm, has a relative wavelength of 450 nm. The intensity is the largest and the relative intensity decreases toward the latter half in the visible light wavelength range (380 nm to 780 nm), and then drops sharply around the wavelength of 650 nm. In addition, the second LED light source 210 (yellow solid line) of the present invention, which is adjusted to a color temperature of 2700K by applying RGB phosphors to the LED chip 200 emitting purple light having a peak wavelength of 400 nm to 408 nm, increases as the wavelength increases. The relative intensity gradually rises, and then the relative intensity is the largest in the vicinity of the wavelength between 600 nm and 650 nm, and then it shows a characteristic of rapidly descending.

The third LED light source 300 (red solid line) emitting red light having a peak wavelength of 660 nm to 780 nm shows a peak wavelength within a range of 660 nm to 780 nm.

In Figure 3, the black dotted line represents the wavelength characteristics of the sunlight implemented by the embodiment of the present invention. It can be seen that it has a spectrum very similar to sunlight (black dotted line), which is natural light.

The relative intensity of sunlight at 700nm corresponds to 60% of the peak at 470nm, and when a red light emitting LED (54mW) with a peak wavelength of 700nm is added to sunlight (120mW), the peak rises by 91% and is 116% at 700nm, so sunlight As in, to achieve 60% of the peak at 700 nm, the sunlight must be 2.6 × 120 mW = 312 mW. Therefore, the power ratio between sunlight and the 700nm red light emitting LED (IR) is 312:54, so it is 5.8:1. and 780 nm, it is 1.9:1. Therefore, the ratio of sunlight and red light emitting LEDs (IR) can be calculated as 1.5:1 to 6:1 as a whole.
