Light emitting diode

摘要

The present invention provides a light emitting diode (2), which comprises a first LED die (20a) and a second LED die (20b), each die comprising a first semi-conductive layer (200), a second semi-conductive layer (202), and a multiple quantum well layer (201) disposed between the first (200) and the second (202) semi-conductive layers, wherein the first semi-conductive layer (200) of the first LED die (20a) is coupled to the second semi-conductive layer (202) of the second LED die (20b) so as to form a serially connected structure whereby the consuming current and heat generation of the light emitting diode (2) are lowered so that the size of heat dissipating device for the light emitting diode (2) can be reduced and illumination of the light emitting diode can be enhanced.
