Patent ID: 7733002

Claim:
A light emitting device comprising a semiconductor light emitting element and a phosphor which converts a part of a luminescence spectrum emitted from the semiconductor light emitting element; wherein said luminescence spectrum of said semiconductor light emitting element is located between a near ultraviolet region and a short-wavelength visible region, wherein said phosphor is made by adding a red luminescent activator to a base material of a blue luminescent phosphor, wherein said phosphor is represented by a general formula of (M 1−x−y Eu x M′ y ) 2 B 5 O 9 M″, where M is at least one selected from the group consisting of Mg, Ca, Ba, Sr, M′ is at least one selected from the group consisting of Mn, Fe, Cr, Sn, 0.0001≦x≦0.5, 0.0001≦y≦0.5, and M″ is at least one halogen selected from the group consisting of F, Cl, Br, I.
