Patent ID: 8203157

Claim:
A lighting device comprising: an LED chip having a light emitting surface, and being configured to emit a light from said light emitting surface; a mounting substrate being configured to mount said LED chip; a first color conversion member comprising a first light transmissive material and a first phosphor, said first phosphor being excited by the light which is emitted from said LED chip, thereby giving off a first light having a wavelength which is longer than a wavelength of the light emitted from said LED chip, said first color conversion member being directly disposed on said light emitting surface of said LED chip, a second color conversion member comprising a second light transmissive material and a second phosphor, said second phosphor being excited by the light which is emitted from said LED chip, thereby giving off a second light having a wavelength which is longer than the wavelength of the light emitted from said LED chip, said second color conversion member being shaped to have a dome-shape, wherein said LED chip and said first color conversion member are disposed between said mounting substrate and said second color conversion member, and wherein said first color conversion member is configured to generate heat having a first amount of heat generation when the first color conversion member is excited by the light which is emitted from said LED chip, said second color conversion member being configured to generate heat having a second amount of heat generation when the second color conversion member is excited by the light which is emitted from said LED chip, and the first amount of the heat generation being greater than the second amount of the heat generation.
