摘要:
A blue-light emitting device, or a pseudo-white-light emitting device, including an LED light source that includes, as a light emission component, blue light having a wavelength of from 420 to 490 nm. A color-renderability improvement member including a complex fluoride fluorophore that absorbs blue light and emits red light and that is represented by A2(M1-xMn)F6 (M is at least one type of tetravalent element selected from Si, Ti, Zr, Hf, Ge, and Sn; A is at least one type of alkali metal selected from Li, Na, K, Rb, and Cs and including at least Na and/or K; and x is from 0.001 to 0.3) is arranged in a location that is outside a region onto which light parallel to the light emission axis of the LED light source is emitted, said region being within a region onto which light is emitted from the LED light source.
