Abstract:
1. A light-emitting diode (LED), which is a positive light-emitting type light emitting diode, comprising: an LED die; at least two metal pads, set on said LED die, wherein the top surfaces of said metal pads set on the same plane essentially; a fluorescent layer, set on a surface of said LED die and said metal pads; said fluorescent layer located on the periphery of said metal pads and not covering said metal pads; said metal pads being exposed; said LED die comprising a first semiconductor layer; a second semiconductor layer, a light-emitting layer, a first electrode and a second electrode; said light-emitting layer set on said first semiconductor layer; said second semiconductor layer set on said light-emitting layer; said second electrode being completely on top of said second semiconductor layer; said first electrode being completely on top of said first semiconductor layer; at least one of said metal pads set on said first electrode, and at least one of said metal pads set on said second electrode; the thickness of the fluorescent layer is greater than 30 μm; and at least part of light with a first wavelength produced by the LED die is converted to light with at least a second wavelength by the fluorescent layer.
