摘要： A light source bulb is fixedly inserted into a lateral direction to the optical axis Ax at a position below an optical axis Ax. Accordingly, a region lateral to the optical axis Ax on a reflection surface of the reflector can be effectively utilized for light distribution control. Furthermore, a first additional reflector having a reflection surface of substantially-spheroidal shape whose first focal point is at a position coincident with the light source is disposed at a position above the optical axis Ax. A second additional reflector 36 having a reflection surface of a substantially-parabolic vertical cross-sectional profile whose focal point is coincident with a second focal point of the first additional reflector is disposed at a position below the optical axis. As a result, light from the light source is illuminated forward without passing through a projection lens.

摘要： A projection-type vehicular headlamp structure that is capable of forming at least two types of light distribution in at least two modes, and is also capable of controlling the radiated light thereof with high precision in addition to keeping to a minimum any noticeable difference when switching between modes. A portion of a reflector is structured as a mobile reflection portion which may separate from a remaining reflective portion. An additional reflector is disposed generally behind the mobile reflective portion. The additional reflector is incident to light from a light source when the mobile reflective portion is separated from the remaining reflective portion. Light incident from the mobile reflective portion, the remaining reflective portion, and the additional reflector is reflected forward to a projection lens of the vehicular headlamp, providing illumination in the area preceding a vehicle's traveling path.

摘要： Light emitted from the light source, which is disposed above an optical axis extending in front and rear direction of a vehicle lighting device, is reflected toward front of the vehicle lighting device by a reflector made of a transmissive member. An exterior surface of the reflector is formed with a plurality of protruding portions extending in a radial pattern with respect to the optical axis. Each of the protruding portions has a total reflection prism having a cross sectional shape perpendicular to the optical axis, which is approximately a V shape. The reflector is divided into twelve fan-shaped reflective regions, each having three protruding portions. The fan-shaped reflective regions, which are located in the left and right directions of the optical axis, reflect the light emitted from the light source in the direction more deviating from a direction along the optical axis than the fan-shaped reflective regions, which are located at the upper and lower directions of the optical axis.

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.
