Abstract
A light emitting diode includes a frame having increased thickness to enable a bowl portion thereof to have an increased depth more than 0.6 mm. Radiating blocks are provided below the frame and a layer of radiation-enhancing material is applied over bottoms of the frame and the radiating blocks to increase a radiating area of the light emitting diode. And, leads are downward extended from two outer sides of the frame. The light emitting diode therefore has increased radiation efficiency and light-emitting efficiency.
