ABSTRACT:
An interior lamp can achieve both an excellent illumination function and an excellent illumination effect (providing a comfortable environment) and may possibly provide high merchandizability characteristics. The interior lamp can include an LED light source unit having a substrate and a plurality of white LED lamps and colored LED lamps mounted on the substrate. A cover case can be provided to serve as a light illumination unit. The light illumination unit can include a double-layer structure having a light diffusion layer and a light transmission layer. The light diffusion layer can have a plurality of penetrating holes. The light transmission layer can have a plurality of convex lens portions. The center axes of the penetrating holes and the corresponding lens portions can coincide with corresponding optical axes of the white LED lamps, respectively. The white light from the white LED lamps can be converged by the respective lens portions of the light transmission layer to be radiated outside as spot light(s). The colored light from the colored LED lamps can be diffused through the light diffusion layer to be radiated outside as diffused light.
