Inner Mongolia No. 1 Middle School Student Invented Color Light LED Has Obtained National Patent

Gao Yanfei, a high school student of Etuokeqian Banner in Erdos City, Inner Mongolia Autonomous Region, invented a color LED, which has obtained national patents. The color LED has the advantages of being able to overcome the phenomenon that the car turn signal and the traffic indicator can not effectively distinguish the flicker under the strong light condition, and strengthen the flickering effect of the car turn signal and the traffic indicator. At the same time of flickering, it can reduce the electric energy consumption which is increased due to insufficient flicker brightness, save energy and reduce the hidden danger of driving safety, and reduce the occurrence of traffic accidents.
The background color of the lamp body can be variously selected to provide imagination and space for the design of the car. The color light LED can be applied to indicator lights such as automobile turn signals and traffic lights, and the materials are environmentally friendly, the social and economic benefits are remarkable, and the market prospect is good.

Its color LED patent number: ZL201020291126.6.
