Light enhancing structure for a light emitting diode

摘要

A light enhancing structure includes a light emitting diode in it and at least one coating layer. The light emitting diode unit includes a plurality of surfaces and a light-emitting surface. The light-emitting surface is for allowing a plurality of lights generated inside the light emitting diode unit to emit through. The coating layer is formed on the surfaces for blocking or reflecting one of the lights generated inside the light emitting diode unit, and to light intensity of the light emitting diode unit is enhanced.
