  • Patent number: 7147354
    Abstract: The invention is to provide an interior illumination lamp which can change lighting directions, not directly touching lenses by the fingers. If rotating fins in the forward direction of the lenses, outer bezels are rotated together, so that a light emitting direction can be adjusted, not directly contacting the lenses with the fingers as conventionally. Even if the lenses are heated, the light emitting directions can be adjusted thereby. Not directly contacting the lenses by the fingers, the lenses are prevented from being stained to decrease illumination. In addition, since the fins avoid the light diffusion, a driver and other riding people are kept off dazzling by the light.
