[0001] OPTICAL SEMICONDUCTOR ILLUMINATION APPARATUS [0002]

The present invention relates to an optical semiconductor lighting apparatus, and more particularly, to an optical semiconductor lighting apparatus that can be installed even in a narrow installation space, as well as to maintain the installation state even in vibration and shock.

Optical semiconductor such as LED or ELD has a lower power consumption than an incandescent lamp and a fluorescent lamp, has a long service life, is excellent in durability, and is one of components widely used for lighting in recent years due to its much higher luminance.

In recent years, such an optical semiconductor has been used for downlight lighting.

Downlights are usually buried in the form of a light fixture, which is almost widely exposed because there is almost no exposure of the light fixture and the ceiling surface looks good.

The downlight is connected to a bracket formed with a rail on a bezel fixed to the installation target surface, a housing equipped with a light source at the end of the bracket is connected, and adjusted by moving the position of the fixture along the rail of the bracket. The structure is fixed to the installation target surface.

In addition, the downlight may have a structure in which a fixture having a clip shape that rotates by mounting a spring instead of a rail according to an installation environment supports a surface to be installed.

However, the conventional downlight as described above has a problem in that the size of the entire lighting device, that is, the length of the bracket is increased by the size of the fixture, so that when the space on the back side of the installation target surface is insufficient, the lighting fixture itself cannot be installed.

In addition, the fasteners of the above-described structure is loosened due to vibration, etc., there is also a problem that the coupling force between the downlight and the installation target surface is weakened or the lighting device itself is struck outside the installation target surface.
