  • Millimeter wave radar-equipped headlamp
    Patent number: 8803728
    Abstract: A millimeter wave radar-equipped headlamp includes a millimeter wave radar that detects an object ahead of a vehicle, and a lighting device unit that irradiates an area ahead of the vehicle. The lighting device unit incorporates an antenna module of the millimeter wave radar. The lighting device unit includes a projection lens, a light source, a reflector, and a shade. The antenna module includes a millimeter wave waveguide, and a millimeter wave reflection mirror. A reflection surface of the millimeter wave reflection mirror is formed by a spheroidal surface having a first focal point located in the vicinity of the opening of the millimeter wave waveguide, and a second focal point located forward of the rear focal point.
