Abstract
The present invention provides a light emitting device, which includes a light emitting diode (LED) chip, a wavelength conversion plate including a fluorescent substance and disposed on a light output surface side of the LED chip, and a sub heat radiation path formed to radiate heat of the wavelength conversion plate. The sub heat radiation path includes a transparent heat-conductive film provided on a surface of the wavelength conversion plate, a heat radiator provided in the vicinity of the LED chip, and a thermal connection member that thermally connects the transparent heat-conductive film to the heat radiator.
