Description

[0001] The present invention relates to an anti-glare LED lighting device,

The present invention relates to an anti-glare LED lighting device, and more particularly, to an anti-glare LED lighting device having a wide opening at a bottom and capable of preventing glare by suppressing the emission of direct light while being installed at a high position.

In recent years, as the consumption of electricity has increased, there has been a growing concern about blackouts in Korea, and a variety of policies have been proposed to reduce power consumption at times of power consumption. For example, if energy consumption is exceeded for each building, it is possible to collect fines for exceeding the standard, change the lunch time of the city, change the working clothes regulations, and adjust the interval of the subway.

As one of the methods for reducing the power consumption, there has been proposed an illumination device using an LED which consumes significantly less power than a conventional incandescent lamp or a fluorescent lamp. However, in the case of the LED lighting device, the price of the LED itself is higher than that of the incandescent lamp or the fluorescent lamp, and since the heat dissipation structure and the power supply device are separately provided, the price is relatively high.

Particularly in a factory where precise work is performed, or in an environment where fine design, assembly or inspection is required, brighter illumination is required compared to the surroundings. In order to apply this environment, a spotlight using LED has been proposed.

An example of an LED illumination device for conventional focused illumination is disclosed in Appl. No. 10-2013-0051247 (LED illumination device, published May 20, 2013) of the present invention. The invention described in Japanese Patent Application Laid-open No. 10-2013-0051247 proposes a power supply housing and a lighting housing separately from each other in order to separate the power supply unit generating mutual heat from the LED light source in the centralized lighting LED lighting apparatus, Respectively.

Such a structure has a very effective structure that can prevent shortening of the lifetime of a central lighting LED lighting device, which is easy to discharge heat and consumes a lot of electric power compared with general lighting.

In addition, since the lighting unit housing can be tilted to adjust the light distribution, it is possible to flexibly cope with the change of the working space. However, since the power source housing, the lighting unit housing, and the connection frame are separately manufactured, the components are assembled to each other, and then the power source housing and the lighting unit housing and the connection frame are assembled together, There is a disadvantage in that the price of the LED illumination device is increased due to a large amount of time and labor.

In addition, the feature of the LED lighting devices for the centralized lighting has a wide downward opening and a mounting height is higher than that of the general lighting, so that the light of the LED is seen in the operator's eyes and the glare is generated.

Such glare may cause the operator to interrupt the concentration of the work, and the visual acuity may be lowered if exposed for a long time.

SUMMARY OF THE INVENTION The present invention has been made in view of the above problems, and it is an object of the present invention to provide an anti-glare LED lighting device capable of preventing the emission of direct light of LEDs and preventing glare.

Another object of the present invention is to provide an anti-glare LED lighting device capable of reducing the number of components to be individually manufactured and shortening the time required for assembly.

Another object of the present invention is to provide an anti-glare LED lighting device capable of preventing a shortening of the service life of an illumination device due to heat generated by effectively emitting heat generated in an LED lighting device for centralized illumination .

According to an aspect of the present invention, there is provided an illumination device for preventing glare, comprising: a lower case part having a plurality of flat inner sides so that a light outlet of the bottom surface is polygonal; A substrate having LEDs mounted thereon such that the light emitting surface faces the central portion of the polygon; and a plurality of projecting portions projecting along the periphery of the lower case portion, And a plurality of inclined surfaces which are coupled to cover the light outlets of the lower case part and each of the LEDs mounted on the substrate is exposed to the side of the light outlets, And a reflecting portion provided to cover the light outlet of the lower case portion, And a cover portion which is a diffusion plate.

The glare-preventing LED illumination device of the present invention has an effect of preventing the glare phenomenon by preventing the direct light of the LED from being seen directly by the naked eye.

In addition, the present invention has the effect of minimizing the manufacturing cost by constructing the case in a single structure and assembling the components such as the power supply, the substrate on which the LED is mounted, and the reflector through the light outlet.

Further, according to the present invention, the heat radiating fins are positioned on the rear surface side of the substrate on which the LEDs are mounted, the heat radiating fins can be effectively heat-exchanged with the outside air by the air current generated by heat, It is possible to prevent the life span from being shortened.

In addition, the present invention has an effect of preventing mutual heat conduction between the power supply part and the LED, which are the cause of heat generation, and preventing damage due to heat conduction.
