Patent number: 12563869Abstract: A light emitting diode device includes an epitaxial layered structure and first and second electrodes that are disposed on the epitaxial layered structure. The second electrode includes a body portion and at least one extending portion connected to the body portion and extending in a direction away from the body portion. The extending portion includes at least one curved section. A projection of the curved section on the epitaxial layered structure includes first and second curved sides that are opposite to each other and that are curved in an identical direction. The first curved side has a first imaginary center of curvature, and the second curved side has a second imaginary center of curvature. A distance between the first imaginary center of curvature and the second imaginary center of curvature is equal to or smaller than 5 ?m.Type: GrantFiled: October 19, 2022Date of Patent: February 24, 2026Assignee: QUANZHOU SANAN SEMICONDUCTOR TECHNOLOGY CO., LTD.Inventors: Linhua Cao, Wanjun Chen, Huining Wang, Heying Tang, Chunlan He, Lili Jiang, Liming Zhang, Renlong Yang, Chung-Ying Chang

Patent number: 12389719Abstract: An LED device includes an epitaxial layered structure that includes a first semiconductor layer, a light emitting layer and a second semiconductor layer, first and second electrodes that are disposed on the epitaxial layered structure, and an insulating structure. The first electrode includes a first body portion and a first extending portion connected together. The first extending portion includes a first part and multiple second parts. A projection of the first part on the first semiconductor layer does not overlap a projection of the insulating structure on the first semiconductor layer. The first part has a first sub-part and multiple second sub-parts. A projection of the first sub-part on the first semiconductor layer has a first length, and a projection of each of the second sub-parts on the first semiconductor layer independently has a second length measured in the same direction. The first length is greater than the second length.Type: GrantFiled: October 24, 2022Date of Patent: August 12, 2025Assignee: XIAMEN SAN'AN OPTOELECTRONICS CO., LTD.Inventors: Huining Wang, Linhua Cao, Hongwei Xia, Chunlan He, Lili Jiang, Su-Hui Lin, Renlong Yang, Chung-Ying Chang

Patent number: 12255269Abstract: A light-emitting device includes a light-emitting laminated structure, a first electrode, and a second electrode. The first electrode has a reflection layer, an intermediate layer, and an electrically conductive layer. The intermediate layer includes a barrier layer having a first repeating paired layer unit and a second repeating paired layer unit, each of which has a platinum layer. The first repeating paired layer unit is closer to the electrically conductive layer than the second repeating paired layer unit, and a thickness of the platinum layer of the first repeating paired layer unit is greater than a thickness of the platinum layer of the second repeating paired layer unit.Type: GrantFiled: July 18, 2022Date of Patent: March 18, 2025Assignee: XIAMEN SAN'AN OPTOELECTRONICS CO., LTD.Inventors: Huining Wang, Hongwei Xia, Quanyang Ma, Jiali Zhuo, Weibin Shi, Su-Hui Lin, Renlong Yang, Chung-Ying Chang
