摘要： As the annular translucent member, an annular lens formed from a peripheral edge portion of a convex-meniscus lens is disposed between a projection lens and a reflector along an outer peripheral edge of the projection lens. Direct light from a light source toward a space beyond the outer periphery of the projection lens is caused to illuminate forward of the lamp by the annular lens, thereby effectively utilizing light source luminous flux. In relation to the above, a shape of a back surface of the annular lens is formed into a spherical surface having its center at a luminescence center of the light source. Accordingly, direct light from the light source can travel straight without being deflected by a back surface of the annular lens, whereby a light deflection angle on a front surface of the annular lens can be calculated easily and with good accuracy.

摘要： A first additional reflector 34 is provided between a light source bulb 22 and a shade 32 and used for reflecting light from a light source 22a to an area in front in the direction of inserting the bulb on the reflective surface 24a of a reflector 24. Further, the area in front in the direction of inserting the bulb on the reflective surface 24a of the reflector 24 is formed as a second additional reflector 36 for reflecting the light reflected from the first additional reflector 34 forward and closer to an optical axis Ax. Thus, direct light from the light source 22a which is to be shielded by the shade 32 is caused to be incident on a projection lens 28 by using the first and second additional reflectors 34 and 36, whereby the direct light can effectively be utilized as forward irradiation light.

摘要： A lamp unit of a vehicular headlamp includes a projection lens with an optical axis; a light source formed from a semiconductor light-emitting element; a first reflector that reflects light from the light source so as to condense such light on or near the optical axis; and a shade positioned between the light source and the projection lens so as to extend along the optical axis direction. The shade shields part of the light reflected by the first reflector. In the lamp unit of the vehicular headlamp, a shielding surface extends rearward from a front end of the shade, where the shade is positioned near a rearward focal point Rf of the projection lens. The shielding surfaces serve as a second reflector that reflects light from the first reflector toward the projection lens. In addition, a transparent portion is formed on part of the second reflector such that part of the light reflected by the first reflector passes downward of the rearward focal point of the projection lens and is then incident to the projection lens.

摘要： A vehicle cornering lamp capable of broadly irradiating a road surface ahead of and in an oblique direction of a vehicle while the vehicle is moving around a curve. The vehicle cornering lamp includes three reflector units 12A, 12B, and 12C, whose light emitting directions are respectively set to angles of 30°, 45°, and 60°, with respect to the traveling direction of the vehicle. The vehicle cornering lamp also includes a control unit 20 for controlling light emission—from the reflector units 12A, 12B, and 12C—according to the travel conditions of the vehicle. When the vehicle turns to the left at an intersection, a traveling road onto which the vehicle will turn left, and a road shoulder, are sufficiently irradiated by switching on the reflector units 12A, 12B and 12C in the order of 12A→12B→12C→12B→12A, so that pedestrians can quickly be detected.

摘要： A lamp includes a projection lens, a light-emitting element disposed rearwardly of a rear-side focal point of the projection lens to be directed upward, a reflector disposed to cover the light-emitting element from an upper side to reflect light from the light-emitting element toward the projection lens, and a shade disposed with an upper end edge thereof passing closely below the rear-side focal point to block part of reflected light from the reflector. Generally the entirety of a portion of the projection lens positioned above the optical axis is cut away. A reflective surface that reflects downward the reflected light from the main reflector is formed on a rear surface of the shade. A sub reflector that reflects forward the reflected light from the reflector reflected by the reflective surface of the shade so as not to be incident on the projection lens is disposed below the shade.
