Abstract:
1. A light emitting device comprising a light emitting element having a main emission peak in the wavelength region of greater than 420 nm and equal to or less than 500 nm, and a phosphor layer formed on the light emitting element, wherein the light emitting element has a junction temperature of from 100° C. to 200° C. at the time of continuous driving of the light emitting device, and the phosphor layer contains a phosphor represented by the following general formula (A), which absorbs the light emitted from the light emitting element and thereby emits light having a main emission peak in the wavelength region of equal to or greater than 650 nm and equal to or less than 665 nm: wherein AE represents at least one or more elements selected from the group consisting of Ca or Sr; HA represents at least one or more elements selected from the group consisting of F or Cl; 2.54≦a≦4.40, 0.80≦b≦1.10, 3.85≦c≦7.00, 0≦d≦2.00, 0≦x≦0.05, 0≦y≦0.10, and 0<z≦0.03.
