SEMICONDUCTOR LIGHT-EMITTING DEVICE

摘要

To provide a semiconductor light emitting device using a large-sized laminated semiconductor light emitting element with improved light extraction efficiency. The semiconductor light emitting device 90 of the present invention includes a semiconductor light emitting element 1 having a semiconductor laminate 40 including a p-type semiconductor layer 43, an active layer 42 and an n-type semiconductor layer 41 sequentially laminated, and a conductive support substrate 10 joined to the p-type semiconductor layer 43 side of the semiconductor laminate 40; a transparent sealing resin 92 covering the semiconductor laminate 40; and fluorescent particles 93 contained in the transparent sealing resin 92. The semiconductor laminate 40 is divided into at least two semiconductor regions 45a to 45d by trenches 2 penetrating the p-type semiconductor layer 43, the active layer 42, and the n-type semiconductor layer 41. The width W of the trench 2 is smaller than the average particle diameter of the fluorescent particle 93.
