  • Patent number: 5942853
    Abstract: The high beam headlight includes a reflector (10) and a light source (12) containing two or more light emitting bodies (20,22). The reflector (10) and the light emitting bodies (20,22) are formed so that reflected light from one light emitting body (20) forms a concentrated or focused high beam issuing from the light source and reflected light from another light emitting body (22) forms a horizontally widened high beam due to horizontal scattering. A control device is provided so that the light emitting bodies (20,22) can either be operated simultaneously or one at a time according to vehicle operating conditions including the condition of the road in front of the vehicle. For example, the high beam formed by energizing only the one light emitting body (22) can be used to form the widened high beam at low vehicle speed, while the light beam formed by energizing only the other light emitting body (20) can be used to form the narrower high beam at high vehicle speed.
