Description

{Constructing structure of Light Emitting Diode Lamp apparatus for fixeding on roof}

The present invention relates to a fastening structure of a ceiling-mounted LED luminaire, and more particularly, to insert a coupling protrusion of a diffusion cover for diffusing light of a light source into a coupling groove of a base composed of a line or a cross shape, It is related to the fastening structure of the ceiling fixed type LED luminaire which combines the fastening groove to easily fasten a plurality of diffusion covers to the body as a single diffusion cover and the fastening structure is stable and the assembly is improved.

Currently, discharge lamps such as fluorescent lamps, incandescent lamps and halogen lamps are used as light sources for indoor lighting in homes and offices. Since the discharge lamp has a high driving voltage, the energy consumption is large due to the boost of the power, and when discharged, the discharge lamp discharges discharge gas such as mercury, which is harmful to the human body or the environment.

In particular, the European Union prohibits the use of harmful substances such as lead, mercury, cadmium, hexavalent chromium (Cr6 +), PBB (polybromide binpenyl) and PBDE (polybrominated diphenyl ether) Establishment of Waste Electrical and Electronic Equipment Directive (WEEE), which allows producers to bear the cost of recycling of hazardous substances (RoHS (Restriction of Use of Hazardous Substances) and waste electrical and electronic products. And it has been implemented since July 1, 2006.

In addition, with the rapid development of LED-related technology, white LEDs emitting white light using blue LEDs and phosphors have emerged. Small size, low power consumption, semi-permanent life, no harmful emissions such as ultraviolet light, no environmentally friendly lighting source without mercury and discharge gas. have.

As a result, in the conventional LED lighting fixture having a lighting device using an LED as a light source in place of a lighting fixture such as a currently used fluorescent lamp,

The fixed LED lamp of Korean Patent Publication No. 10-1128771 (2012.03.23.) Is a fixed LED light fixture coupled to a support provided on a ceiling or a wall of a building, wherein the fixed LED light fixture is an LED lighting lamp and a mounting bracket.
