<P>PROBLEM TO BE SOLVED: To provide a lighting device, of which a light source formed of a solid-state light emitting device such as an LED exhibits high color rendering properties comparable to a halogen light bulb or the like, and is suitable for a light source of a store. <P>SOLUTION: The lighting device includes: a white light emitting part 2 formed of blue LED chips 2a and phosphor-containing layers 2b mounted on a base 1, and emitting white light with a color temperature of 2500-3200 K; a reflector 3 for reflecting the light from the white light emitting part 2; and a visible light selective absorption layer 6 arranged on the upper surface of a light emitting unit 4 formed of the reflector 3 and white light emitting part 2. The visible light selective absorption layer 6 is formed by containing and dispersing a visible light selective absorption material having an absorption peak in a wavelength range of 575-600 nm in translucent material. <P>COPYRIGHT: (C)2011,JPO&INPIT |
