Description

LED lighting apparatus {LED lighting apparatus}

The present invention relates to an LED (LED) luminaire, and more particularly, to prevent the light emitted from each of the plurality of LEDs installed in the vertical and horizontal arrangement on the LED module mounted inside the luminaire case does not appear as a point light source in the light cover; At the same time the present invention relates to an improved LED luminaire so that the light emitted from each of the plurality of LEDs can be transmitted through the entire lighting cover with the same brightness.

In general, incandescent lamps and fluorescent lamps are mainly used in the ceiling or wall lamps indoors. The incandescent lamps are cheaper than fluorescent lamps, but the power consumption is high, the heat generation is very high, and the service life is short. On the other hand, the fluorescent lamps are more expensive than incandescent bulbs, but have low power consumption and long service life. Therefore, fluorescent lamps using fluorescent lamps have been frequently used in homes, department stores, and large discount stores.

However, the above-described fluorescent lamps have also been pointed out as a cumbersome and inconvenient problem, because after a certain period of time, the fluorescent lamp is cut off due to the end of its useful life.

Therefore, recently, the luminaire using a light emitting diode (LED: Ligft emitting diode) with a very low power consumption and a long service life compared to a fluorescent lamp has been proposed and is rapidly spreading.

By the way, the LED has the advantage of being able to illuminate bright light even at low power, while the LED light emitted from the light emitting chip (chip) has a straight line LED module mounted on the luminaire installed in the ceiling or wall of the room The light emitted from each of the plurality of LEDs constituting the light tends to appear as a spot light on the lighting cover of the luminaire, and the lights appearing as a point light source on the lighting cover allow people living in the room to look at the luminaire. It has been pointed out that the glare phenomenon occurs due to the LED light transmitted through the light cover to the point light source. In order to eliminate the glare phenomenon, the diffused light is emitted from the LED to prevent it from appearing as a point light source. I developed, and the above diffusion agent is applied to the lighting cover of the LED luminaire There.

However, as described above, the diffusion agent applied to the lighting cover of the LED luminaire diffuses the light emitted from the plurality of LEDs arranged on the printed circuit board of the LED module so that the light emitted from each of the LEDs does not pass through the light cover as a point light source. Although it can be expected that the effect of avoiding the light emitted from each of the plurality of LEDs are concentrated, the light is transmitted through the bright light, but the light of each of the LEDs are not concentrated, that is, the edge portion of the lighting cover is a plurality of The phenomenon that the LED light is transmitted through the dark light as compared to the light condensing part is generated, causing problems such as deterioration of the quality of the LED luminaire.

This is because most of the LED modules mounted in the conventional LED luminaires have a flat plate made of a printed circuit board in which a plurality of LEDs are arranged horizontally and horizontally. Problems occurring in the luminaire will be described with reference to the illustration of FIG. 9 as follows.

Conventional LED lighting is illuminated by the light emitted from each of a plurality of LEDs 210 installed in the LED module 200 mounted inside the luminaire case 100, the LED module 200 is printed on a flat plate Since the plurality of LEDs 210 are arranged vertically and horizontally on the circuit board 220, the lights emitted from each of the plurality of LEDs 210 are mounted to the reflector 110 of the luminaire case 100. The portion D 1 condensed on the cover 300 is transmitted by bright light, while the portion D 2 on which the light emitted from the LED located at the edge of the plurality of LEDs 210 is not collected is plural. The light emitted from the LEDs 210 of the portion (D 1 ) is a phenomenon that is transmitted through the dark light appears, this phenomenon occurs when people living in the room when looking at the light cover 300 of the LED luminaire The lights of the LED 210 house That portion (D 1) is part of the bright and the periphery (D 2) has been pointed out as a problem are displayed in the dark state to drop the quality of the LED lamp.

Therefore, as shown in FIG. 10, the reflector 110 of the luminaire case 100 is disposed on the LED module to prevent the portion D 2 from which lights emitted from each of the plurality of LEDs 210 are not collected. In the case where the light emitting angle of the light emitted from each of the LEDs arranged at the edge of the printed circuit board 220 of the 200 is narrowly formed within the range of the light emission angle, the dark portion D 2 may be prevented from appearing. The problem is that the illumination range of N becomes narrow.

The present invention has been proposed to solve the above-mentioned problems in the prior art, and improves the structure of the LED module mounted on the LED luminaire to emit light from each of the plurality of LEDs arranged in the longitudinal direction on the printed circuit board It is an object of the present invention to provide the LED luminaires whose quality is improved so that the illumination range widens by allowing the lights to penetrate the entire lighting cover brightly.

The present invention as a means for achieving the above object,
