Description

The present invention relates to a structure using a light emitting diode as a light source for illumination.

Light emitting diodes (LEDs) have the characteristics of small volume, low calorific value, low power consumption, and long service life. In addition to this, with the recent progress in manufacturing technology, the light emission luminance continues to improve, and the manufacturing cost gradually decreases. For this reason, in the future, LED light sources will replace the current mainstream incandescent lamps, fluorescent lamps, and even power saving lamps, and will be the most important light-emitting component in lighting equipment. Even now, LEDs are already used for traffic lights, traffic lights, billboards, and backlight sources for liquid crystal displays.
