Abstract
Description
The present invention relates to an LED lighting device, and more particularly, to an LED lighting device embedded in a ceiling.
BACKGROUND ART [0002] Generally, illumination devices including an LED illumination device basically take a form of emitting light at a surface for diffusion. This is common to both the bulb type illuminating device, the surface illuminating device, and the stand type illuminating device, and the beauty of illumination is determined not by the light itself but by the specificity or color of the external design of the illuminating device.
As an example of the surface emitting type illumination device, the surface illuminating device uses a diffusion plate having a predetermined area as a cover. An example of this is Registration No. 10-0998980 (registered on Dec. 1, 2010). 4, which is a representative drawing of the above-mentioned patent, includes a substrate on which a plurality of LEDs are arranged to emit light upward, and at least one diffusion layer is included on the upper side of the substrate, So as to illuminate the entire surface of a specific size with a uniform illumination.
Such a structure is a general construction of a conventional illumination device that emits light from the surface described above. The diffuser plate prevents the light from being partially emitted intensively, thereby preventing the occurrence of glare. However, . This lowering of the light efficiency causes the energy consumption efficiency of the lighting apparatus to be lowered because more power must be used for lighting of the same illuminance.
That is, in order to provide a planar light source of sufficient illumination, a large number of LEDs must be used more than necessary, so that the advantage of low power consumption of the LED illumination is reduced and it is not easy to handle heat emitted from the LED, There is a problem in that the life of the battery can be shortened.
As a prior art for a ceiling embedded lighting which is generally called a 'down light', a structure and an action of a down light are described in detail in a registered patent 10-114334 (registered as of April 30, 2012) .
Fig. 1 is a representative view of the above-mentioned patent 10-114334.
1, a conventional LED light device includes a printed
And a heat sink (3) for transferring the heat of the printed circuit board (4) to the heat sink (1).
A separate heat sink 1 is used to dissipate the heat generated in the printed
This is because the
Also, since the heat sink 1, the
In the conventional drawings and the like, there is no mention of a power supply device for supplying a DC constant power source to the
Therefore, when the power supply unit is to be installed at a different position, the power supply unit must be connected to the printed
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 LED lighting device which is installed only at the periphery of an illumination device to prevent heat concentration and facilitate heat emission.
Another object of the present invention is to provide an LED lighting device capable of accommodating a power supply unit and simplifying wiring work.
It is another object of the present invention to provide an LED lighting device in which a power supply unit and a substrate are installed in an interior of a room through a light outlet, and the connection is made without a separate fastening means.
According to the present invention, the housing is divided into an upper housing and a lower housing, the lower housing is made of a resin material, the upper housing is made of a metal material, and materials suitable for the respective characteristics are used. .
And an object thereof is to provide an LED lighting device capable of firmly fixing a diffusion plate without being fastened by a fastening means.
In addition, the present invention can not only prevent glare but also illuminate the installed ceiling, and the present invention can be used for display of the compartment.
In order to solve the above-mentioned problems, an LED illumination apparatus according to the present invention includes a
The LED lighting apparatus according to the present invention has the effect of increasing the heat emission efficiency by providing the LED only in the peripheral portion except for the central portion of the substrate horizontally installed on the ceiling in the lighting apparatus having the structure embedded in the ceiling.
Further, since the upper housing and the radiating fin are integrally formed, the present invention does not require a separate assembly process, thereby reducing the manufacturing cost and improving the productivity.
According to the present invention, an upper housing is made of a metal material, a power source is built in the upper housing, and an upper edge of the substrate is directly in contact with a bottom surface of the upper housing to easily dissipate the heat of the LED mounted on the substrate have.
In addition, according to the present invention, when the lower housing is formed, the diffusion plate is inserted into the lower housing before the forming heat, and when the lower housing is cooled, the diffusion plate can be firmly fixed, So that the manufacturing cost can be reduced and the productivity can be improved.
According to the present invention, a diffusion part extending downward from the periphery of the light emission port is provided to prevent the occurrence of glare, and a part capable of displaying a color in the diffusion part can be provided, There is an easy effect.
