HIGH BRIGHTNESS LIGHT EMITTING APPARATUS

摘要

The present invention relates to a light emitting apparatus. The apparatus comprises a high intensity light source (102) arranged to emit light of a first wavelength (110) onto a wavelength converting member (104, 300a, 300b, 300c), wherein the wavelength converting member is arranged to emit the light of a second wavelength (112) and transmit and/or reflect light of the first wavelength; and a collecting lens 108 arranged to collect light emitted, transmitted, and/or reflected from the wavelength converting member. The wavelength converting member comprises: a wavelength converting element (302) arranged to convert the light of the first wavelength into light of the second wavelength, a reflective heat conducting element (304) arranged to reflect light of the second wavelength, and a beam shaping heat conducting element (306) arranged to transmit light of the first and the second wavelengths, wherein the beam shaping heat conducting element is arranged to direct light of the first and the second wavelengths with an angular distribution within a collection angle of the collecting lens; and wherein the wavelength converting element is in direct thermal contact with the beam shaping heat conducting element and in thermal contact with the reflective heat conducting element.
