Title:
交流駆動型の発光ダイオード
Document Type and Number:
Japanese Patent JP5799124
Kind Code:
B2
Abstract:
AC LED according to the present invention comprises a substrate (51), and at least one serial array having a plurality of light emitting cells connected in series on the substrate. Each of the light emitting cells comprises a lower semiconductor layer consisting of a first conductive compound semiconductor layer formed on top of the substrate (55), an upper semiconductor layer (59) consisting of a second conductive compound semiconductor layer formed on top of the lower semiconductor layer, an active layer (57) interposed between the lower and upper semiconductor layers, a lower electrode (65) formed on the lower semiconductor layer exposed at a first corner of the substrate, an upper electrode layer (61) formed on the upper semiconductor layer, and an upper electrode pad (64) formed on the upper electrode layer exposed at a second corner of the substrate. The upper electrode pad and the lower electrode are respectively disposed at the corners diagonally opposite to each other, and the respective light emitting cells are arranged so that the upper electrode pad and the lower electrode of one of the light emitting cells are symmetric with respect to those of adjacent another of the light emitting cells.
