Title:
LIGHT EMITTING DIODE LAMP
Document Type and Number:
WIPO Patent Application WO/2012/165786
Kind Code:
A3
Abstract:
The present invention relates to a coupling structure for a light emitting diode (LED) lamp, and more particularly, to an LED lamp in which, in order to reduce the high manufacturing cost of a conventional lamp, an SMPS case and a body case made of aluminum (which renders the unit heavy and has high electricity consumption) of same are replaced with a white-light diffusing polycarbonate material, such that the cases may be lightened. Further, by forming sloped angles at both end portions of a frame for a printed circuit board (PCB), light from the LED lamp may be emitted in four directions so as to enable peripheral lighting over a wide angle; by forming convex lenses in a honeycomb (beehive) configuration in a transparent lens unit, wide peripheral lighting may be maintained and glare may be reduced through the light-distribution effect, and even when any one of a plurality of LEDs is damaged, the external appearance of the LED lamp will not be diminished since the internal structure thereof is not visible in detail; by forming the coupling structure of a lens unit and the body case as a hook type, the structure may be coupled with one touch thus enabling easy coupling, and by forming a plurality of air holes in a shape bent downward from the perimeter of the SMPS case coupled to the body case, heat generated within the LED lamp may be easily dispersed to the outside, and water or moisture may be completely blocked from infiltrating the LED lamp.
