LIGHT-EMITTING DIODE, AND LIGHT-EMITTING DEVICE AND VEHICLE LAMP COMPRISING SAME
Document Type and Number:
WIPO Patent Application WO/2024/007479
Kind Code:
A1
Abstract:
Disclosed in the present invention is a light-emitting diode, comprising a metal substrate, and a semiconductor layer sequence arranged above the metal substrate, the semiconductor layer sequence being at least composed of a first-type semiconductor layer, a second-type semiconductor layer, and an active layer located between the first-type semiconductor layer and the second-type semiconductor layer. The light-emitting diode further comprises a first electrode and a second electrode; the first electrode is electrically connected to the first-type semiconductor layer; the second electrode is electrically connected to the second-type semiconductor layer; the metal substrate comprises a first metal layer; a groove is formed in the side of the metal substrate distant from the semiconductor layer sequence; a second metal layer is arranged in the groove; the groove is provided with a protruding groove edge; and the groove edge is not more than 0.5 micrometer higher than the second metal layer. Therefore, the reliability of a product after packaging and bonding of the light-emitting diode is improved.
