SEMICONDUCTOR LIGHT EMITTING DEVICE |
摘要 |
According to one embodiment, a semiconductor light-emitting device includes a semiconductor layer including a light emitting layer; and a phosphor layer provided on the semiconductor layer. The phosphor layer includes a plurality of phosphors, −0.05<A×(AR)+B×(Np)+C<0.05 being satisfied for −0.149055−(3×0.011797)≦constant A≦−0.149055+(3×0.011797), −0.000192−(3×0.00002461)≦constant B≦−0.000192+(3×0.00002461), and 0.0818492−(3×0.005708)≦constant C≦0.0818492+(3×0.005708). AR is a ratio of a thickness of the phosphor layer to a width of the phosphor layer, and Np is a number of the plurality of phosphors. |
