摘要： A vehicle light can be configured to reduce the difference between the cut-off line of the actual light distribution pattern and the cut-off line of the designed light distribution pattern. The vehicle light can include a light source, first reflectors configured to reflect light from the light source, corresponding second reflectors configured to reflect light from the respective first reflectors, and a support member configured to support the light source. The support member and the first reflectors can be separately formed. Furthermore, edge portions configured to form cut-off lines in the light distribution pattern by the second reflectors can be provided in the support member instead of in the first reflectors.

摘要： A vehicle headlamp comprises a revolution paraboloidal reflector attached to the lower portion of a housing, facing in an upward direction, and a rectangular front lens located in front thereof. A lamp is located so that the position of the filament is at the focus of the revolution paraboloidal reflector. A front flat reflector is provided in front of the paraboloidal reflector and reflects the light beam therefrom toward the front lens with a reflecting angle of about 90.degree.. A back flat reflector, mounted parallel to the front reflector, and pairs of flat side reflectors are provided to change the course of a part of the light beam toward the front lens, the resulting light distribution pattern on the front lens being substantially rectangular.

摘要： A long, tubular incandescent lamp has incorporated therein a filament formed by coupling light emitting segments and non-light-emitting segments alternately with each other. Each of the light emitting segments is composed of a light emitting coil and a coil-like coupling member of a larger pitch than the light emitting coil. Each of the non-light-emitting segments is composed of a bar formed to have a straight short-circuit part, bent portions at both ends thereof and supports respectively extending from the bent portions. The short-circuit part is inserted into the coil-like coupling member and these elements are then welded to each other to obtain the filament of alternately coupled light emitting and non-light-emitting segments. The composite filament is subsequently sealed in a long, tubular bulb. Thus, the resulting incandescent lamp is easily assembled, simple in structure, and highly shock resistant.

摘要： A vehicle light can include a light source, a reflector configured to reflect light emitted from the light source in an irradiation direction of a vehicle on which the vehicle light is mounted, and a diffusion plate for diffusion of light and which can irradiate light in the irradiation direction. In this configuration, the diffusion plate can be configured such that light emitted from the light source and light reflected by the reflector enter the diffusion plate and pass therethrough while being refracted. The light is emitted from the diffusion plate in the irradiation direction while being diffused. At the same time, light which is incident on the diffusion plate and is reflected by the diffusion plate is diffused and irradiated in the irradiation direction of the vehicle light. The end portion of the diffusion plate can be bent or curved so as to diffuse the light reflected by the diffusion plate.

摘要： A vehicle light can include a projector type unit and an ellipse-parabola combined unit that surrounds a light source. Part of the light from the light source is directed toward a projector lens by part of an ellipse group reflecting portion of the projector type unit. The remainder of the light is directed toward a parabolic group reflecting portion of the ellipse-parabola combined unit by the ellipse group reflecting portion of the ellipse-parabola combined unit via openings. This parabolic group reflecting portion then directs the light to its illumination direction. This can improve light utilization efficiency, and the entire front face of the vehicle light can be lit without deteriorating from the vehicle light's light distribution.

摘要： A vehicle headlight can project a low beam and a high beam in a reasonable and efficient fashion and does not require a maximum output during high beam illumination, which is low in frequency of use. A light source can be arranged so that a main optical axis thereof forms an angle of approximately 30° to 60° with respect to a front-to-back direction of a vehicle/vehicle headlight. An extremity of the light source can extend toward the front and side of the vehicle. Part of a first reflector can be arranged closer to the front and a center of the vehicle than the light source. A second reflector can be configured to collect light from the first reflector and reflect the same light to the front of the vehicle. The second reflector can be located behind and closer to the side of the vehicle than the light source is. A distribution pattern switching unit can be located between the first reflector and the second reflector. The first reflector and the second reflector can be configured to provide a maximum output during low beam illumination. Part of the light from the first reflector that is to be projected to the lower half of the low beam distribution pattern during low beam illumination can be reflected by a reflecting plate of the distribution pattern switching unit and projected towards a location above a horizontal level during high beam illumination.
