Abstract
The innovative LED structure of the present invention mixes certain materials which can change the wave length of light in the resin of a LED and enables the LED to generate a white light and lights of various other colors as well. The shortcomings of conventional LEDs may be improved upon. By coating different fluorescent materials on the surface of a ultra violet light LED chip, it is possible to obtain a LED able to emit various colored light.
