Abstract

A light emitting device includes a semiconductor light source device including a plurality of semiconductor light emitting elements, a wavelength conversion member that converts a wavelength of irradiation light from the semiconductor light source device, a concentrating lens that disposed between the semiconductor light source device and the wavelength conversion member and concentrates the irradiation light from the semiconductor light source device, and a cylindrical holder. The semiconductor light source device, the wavelength conversion member and the concentrating lens is supported by a support portion provided in an inner diameter portion of the cylindrical holder.
