Description

{ LED lighting device capable of intensive and uniform light irradiation through light distribution angle control }

The present invention relates to a high-power asymmetric LED lighting device capable of uniformly irradiating light and preventing interference between light sources, and more particularly, reflection of light so that light irradiated from an LED light source can be irradiated in a predetermined direction according to the purpose of use. It relates to a high-power asymmetric LED lighting device including a reflector for controlling an angle, and a cover reflector for preventing inter-line interference of light emitted from an LED light source.

The content described in this section merely provides background information on the present invention and does not constitute the prior art.

Compared to conventional lighting, LEDs have a greater brightness, longer lifespan, and lower power consumption. Recently, products that replace conventional lighting applied to street lamps and indoor lamps with LEDs are being developed. LED lighting has an advantage in that the brightness of light is greater than that of conventional light sources, but has a disadvantage in that the uniformity and concentration of light may be somewhat low.

In order to solve this problem, the existing LED lights are provided with reflector means or lens means (light distribution means) of various structures for improving the uniformity and concentration of light.

The prior art (Patent Publication No. 10-2014-0123866) is used to condense the light emitted by the LED device by being coupled to a PCB substrate on which the LED device is installed in order to improve the lighting characteristics of the LED device, and a through hole having a narrow inner diameter. Use the reflector to be formed.

Such a configuration is a general configuration of a conventional lighting device that emits light from the surface described above, and the diffusion plate has an effect of preventing glare by preventing light from being intensively emitted from a part, but has a large amount of light loss, so the light efficiency is high. There was a problem of this deterioration. This decrease in light efficiency causes a decrease in energy consumption efficiency of the lighting device because more power must be used for lighting of the same illuminance.

This has a limitation in adjusting the irradiation angle range because each LED includes a light distribution structure surrounding each LED. Another conventional lighting device also uses a lens structure for light distribution. The lens structure can be relatively easy to adjust the irradiation angle range by simply replacing the lens designed for the situation, but there is a problem in that light cannot be irradiated or light is leaked to the side due to diffuse reflection due to inter-line interference between lenses.

Lighting applied to large spaces such as large sports facilities, airports, and ports may aim to increase the distance that light can reach by narrowing the irradiation range of light. However, the above prior art has a limit in increasing the reaching distance by narrowing the irradiation angle range of light or achieving an appropriate reaching distance, and irradiation efficiency may be reduced due to leaking light.

Therefore, as the irradiation range of light is adjusted so as to solve the problems of the prior art, the light reaching distance is adjusted, and if necessary, the light reaching distance is increased as much as possible to develop a lighting device suitable for application to a large space.

In order to solve the problems of the above-mentioned conventional high-power asymmetric LED lighting device, some domestic and foreign related companies have conducted research on a high-power asymmetric LED lighting device capable of irradiating light with uniform illuminance and preventing interference between light sources. Compared to the conventional high-power asymmetric LED lighting device, the cost is too high to have a structure capable of irradiating light with uniform illumination and preventing interference between light sources for actual commercialization, or even if it is not, the effect against the manufacturing cost of the device is not large. There was no case of commercialization due to lack of competitiveness.

The center of the lighting unit 200 may be located at a focal length of the illustrated parabolic curve. When the center of the illumination unit 200 to which light is irradiated is located at the focal point, reversely using the structural principle of the parabolic curve, which is configured so that all lights incident from the outside and reflected on the inner surface are focused on the focal point, in the illumination unit 200 Lights directed to the side 160 of 150 may be reflected from the inner surface and irradiated to the outside in a straight line.

The parabolic curve may be formed with its central axis inclined by *?*. According to this configuration, as described above, the main irradiation direction (principal axis) of light is

It may be formed so that the overall irradiation direction of the light is inclined toward the lower side by making an inclination as much as possible. The lighting device according to an embodiment of the present invention is positioned relatively high on the edge of a large space such as an airport, a port, a sports facility, etc. to illuminate at least a part of the space, and as the main optical axis is directed downward by the side part 160 , It can illuminate the space more effectively.

The plurality of flat plates may be configured to have a narrower width as they are adjacent to the lighting unit 200 and increase in width as they move away from each other. As the distance from the lighting unit 200 increases, the angle of irradiation of the light increases. Accordingly, the flat plate can be formed to have a greater width as the distance from the lighting unit 200 increases.
