Abstract
A passenger-cabin lighting device comprises as follows. A transparent member is made of synthetic resin not containing scattering material, and has a light emitting surface and a light reflecting surface. A semitransparent member is made of semitransparent synthetic resin containing the scattering material. The semitransparent member is bonded to an inside of the transparent member to constitute a light emitting body. A plurality of light emitting diodes are diposed on one end face of the light emitting body for projecting light into the transparent member and the semitransparent member. A control circuit controls flickering of the plurality of light emitting diodes. The thus constructed passenger-cabin lighting device may be used for lighting and illuminating the passenger cabin, and for highlighting the car itself.
