    摘要: A rear window stop lamp for a motor vehicle, which is energizable when the brake of the motor vehicle is applied, has a resin-molded body attached to the interior side of a rear window glass sheet. The resin-molded body has at least one cavity having a curved reflecting surface. An LED chip is disposed in the cavity substantially at a focal point of the curved reflecting surface. A transparent resin-molded body surrounds the LED chip. A light distribution lens plate covers an opening of the cavity for directing rearwardly a light beam emitted from the LED chip and reflected by the curved reflecting surface. The light distribution lens plate comprises a Fresnel lens. A printed electric wire board is embedded in the resin-molded body for energizing LED units. The printed electric wire board is made of a material having a coefficient of thermal expansion which is closer to that of the rear window glass sheet than to that of the resin-molded body. A thermal expansion inhibiting plate, also embedded in the resin-molded body, is made of a material having a coefficient of thermal expansion which is closer to that of the rear window glass sheet than to that of the resin-molded body.
