  • Patent number: 9029898
    Abstract: The present invention relates to a light emitting diode (LED). The LED comprises an LED die, one or more metal pads, and a fluorescent layer. The characteristics of the present invention include that the metals pads are left exposed for the convenience of subsequent wiring and packaging processes. In addition, the LED provided by the present invention is a single light-mixing chip, which can be packaged directly without the need of coating fluorescent powders on the packaging glue. Because the fluorescent layer and the packaging glue are not processed simultaneously and are of different materials, the stress problem in the packaged LED can be reduced effectively.
