Abstract:
A light-emitting device, comprising a light-emitting crystal element (201), an optical transparent body element (202) arranged next to the light-emitting crystal element (201), a first solid state light source (103), a second solid state light source (104), and a light extractor (105). The first solid state light source (103) is arranged at a transparent body element back end surface of the the optical transparent body (202), and the light extractor (105) is arranged at a crystal element front end surface of the light-emitting crystal element (201) and partially covers a transparent body element front end surface of the optical transparent body element (202). The light-emitting crystal element (201) consists of a single light emitting crystal (101) or consists of a plurality of sequentially arranged light-emitting crystals (101). The optical transparent body element (202) consists of an optical transparent body (102) or consists of a sequential arrangement of the optical transparent body (102) and the light-emitting crystal (101). The second solid state light source (104) is arranged on a side surface of the light-emitting crystal (101) and is used to output excitation light towards the light-emitting crystal (101).
