HEADLIGHT FOR VEHICLES
A headlight for vehicles, with a light source, a reflector arrangement containing at least one reflector module, a first reflector, which has a reflector surface having a first focal point and a second focal point, the light source being arranged at the first focal point, and a second reflector, which has a reflector surface having a focal point that coincides with the second focal point of the first reflector. The first reflector is arranged in front of the light source in the main radiation direction, the reflector surface of the first reflector being curved, with a first opening portion arranged counter to the main radiation direction and with a second opening portion arranged in a manner offset by 90° in relation to the first opening portion and facing towards the second reflector. The reflector surface of the second reflector has free-form parts such that light striking the reflector surface of the second reflector is reflected in such a way that a light distribution having a predetermined light/dark boundary is produced.
Luminous module for vehicle lighting device with deviating light guide
A vehicle luminous module intended to generate a light beam along an optical axis includes primary light guides each including an entrance dioptric interface and an exit, and a light source arranged facing an entrance dioptric interface. A projecting assembly includes a focal region and an exit member, the projecting assembly being arranged so that the light rays passing through said focal region and reaching the exit member are imaged in a projection field downstream of said projecting assembly. The exits of the guides are arranged level with the focal region. The luminous module includes at least one secondary light guide distinct from the primary light guides, and arranged so as to deviate light rays generated by the light source so that they do not reach the exit member, and/or so as to spread said light rays in said projection field.
Automobile lamp lighting system, automobile lamp assembly and automobile
The present disclosure provides an automobile lamp lighting system, including a light source, a reflecting mirror, a light-shielding plate, and a lens. The lens includes a reflecting surface and a refracting surface opposite to the reflecting surface. When an external parallel light is incident into the lens, the external parallel light sequentially passes through the refracting surface for a first refraction, is reflected by the reflecting surface, passes through the refracting surface for a second refraction, exits the lens, and is converged to form a focal point. The reflecting mirror includes a near focal point and a far focal point, the light source is arranged at the near focal point, and the far focal point is located near the focal point of the lens. The light-shielding plate includes a light-shielding plate cut-off line located at the focal point of the lens.
Straddled vehicle and lighting device for straddled vehicle
A first inclined surface and a second inclined surface are inclined with respect to an optical axis of a light emitting diode. The first inclined surface guides light from the light emitting diode guided in the first light transmitting portion toward an outside of an outer lens. An inclination angle of the second inclined surface with respect to the optical axis is larger than an inclination angle of the first inclined surface with respect to the optical axis. The second inclined surface reflects the light from the light emitting diode guided in the first light transmitting portion toward the second light transmitting portion and guides the light into the second light transmitting portion.
