Semiconductor light-emitting device, lighting module, lighting device and method for manufacturing semiconductor light-emitting device |
摘要 |
A semiconductor light-emitting device includes: a semiconductor multilayer film, a substrate supporting the semiconductor multilayer film; and a phosphor layer formed on the substrate so as to cover the semiconductor multilayer film. The phosphor layer has an outer edge of a cross section taken in a direction parallel to the principal surface of the substrate having a substantially circular shape or a substantially regular polygonal shape having five or more sides. An outer edge of the principal surface of the substrate is formed in a substantially circular shape or a substantially regular polygonal shape having five or more sides. With this configuration, light obtained therefrom has less non-uniformity in color and a high luminous flux can be realized.
