New invention to accelerate the process of replacing the LED lamp

Days ago, according to the reports, a professor of beauty has invented 99% efficiency for LED to replace the lamp reflector, is expected to accelerate the process of.

In the invention, the red and blue omnidirectional reflector LED, its brightness is two times more than the previous LED. In LED, the light is emitted from all directions in the interior of the semiconductor, but the newly invented omnidirectional mirror can reflect light very uniformly regardless of the incident angle. Other types of reflectors are valid only when the incident angle is normal or the light is perpendicular to the mirror.

The omnidirectional reflector is made by combining the silver mirror with the LED chip. With a row of micron lithography method to make the size of the hole in a dielectric layer on the dielectric layer, and then deposited onto the bottom of LED semiconductor; in dielectric deposited on a thin layer of silver, and silver through a semiconductor dielectric dielectric below the hole of the formation of a row of micro contact point. The current flowing on the back surface of the micro silver contact is used to activate the semiconductor layer. The omnidirectional light is reflected through the back of the silver contact, through the LED top layer, the efficiency can be more than 99%.

Another expert said the technical progress made recently in LED may cause LED to replace the lamp in the next 5 years.
