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