High light-extraction efficiency light-emitting diode structure
The present invention discloses a high light-extraction efficiency LED structure, wherein metallic pads and metallic mesh wires made of an aluminum-silver alloy are formed on an LED, whereby the high-reflectivity aluminum-silver alloy makes the light incident on the metallic pads and metallic mesh wires reflected once more or repeatedly and then emitted from the surface or lateral side of the LED, wherefore the present invention can decrease the light loss and increase the light-extraction efficiency.
