ABSTRACT:
A lighting device for an elevator car including light sources for emitting light toward the interior of the elevator car and a spectral resolution filter spaced apart and facing the light sources for spectrally resolving the light emitted from the light sources into spectral light with varying colors. The light sources may take the form of a combination of a mirror ball with reflecting surfaces on its outer periphery and a light projector or the form of a plurality of point light sources mounted in a dispersed pattern. The spectral resolution filter may take the form of a flat half mirror surface of a semisphere.
