LIGHT EMITTING DEVICE AND ILLUMINATION INSTRUMENT USING THE SAME

摘要

A light emitting device includes: a plurality of LED mounted substrates (4), each having an LED element (12) emitting light of a short wavelength; a case (2) having a concave portion having a reflection surface (2a) on which a wavelength conversion unit (3) is arranged for emitting converted light by the short-wavelength light of the LED element (12); and a thermo-conductive substrate support plate (5) standing at the center portion of the bottom of the concave portion of the case (2). The reflection surface (2a) is a parabolic plane formed along the both sides of the LED substrate support plate (5). The LED mounted substrates (4) are arranged at the both sides of the LED substrate support plate (5) in such a manner that the light emitting surfaces of the LED elements (12) face the reflection surface (2a).
