ABSTRACT:
A lighting device for an elevator car having walls including a plurality of light sources for emitting light, and a reflection panel adapted to reflect light from the light sources. The reflection panel comprises a metal mirror decorative panel in the form of a spectral resolution reflecting panel having a reflecting diffraction grating which is composed of a plurality of fine mirror reflection surfaces and a plurality of fine frosted surfaces. The light emitted from the light sources is spectrally resolved into spectral light of excellent coloring by the light diffracting action of the reflecting diffraction grating on the spectral resolution reflecting panel so that the illumination of the elevator car interior is greatly improved in terms of luminance and hue thereof.
