摘要： A vehicle light assembly includes a reflector having apertures formed in a circumferential wall thereof which are configured to accept light emitting diodes therethrough in an orientation generally perpendicular to the circumferential wall. The reflector includes a reflective protuberance, which is typically multi-faceted, extending upwardly from an interior surface of the reflector and generally centered with respect to the light emitting diodes. Each facet of the protuberance directs light from the light emitting diodes to an upper lens. Multiple ridges extend upwardly from the interior surface of the reflector at approximately forty-five degree angles with respect to the light emitting diodes for directing the light emitted from the light emitting diodes to the lens. The configuration of the reflector enables the use of fewer light emitting diodes.

摘要： A motor-vehicle light comprises a hollow body with a transparent element facing a main reflective structure which reflects the light rays coming from a source arranged at one side of the main reflective structure towards the transparent element, an auxiliary reflective element being associated with the light source. The main reflective structure has a shell-like configuration, which is visible from the outside since the transparent element has no optical elements. The shell-like configuration comprises a plurality of optically active surface sectors alternated to connecting walls which are substantially radial with respect to the source. The optically active sectors are geometrically generated by translation or rotation of a family of generating curves each having undulations with a pitch substantially lower than the pitch of the distribution of the optically active surface sectors.

摘要： An automobile reflector assembly includes a reflector having reflective protrusions extending from a reflective surface thereof, and a plurality of light emitting diodes disposed adjacent to the reflective surface. A lens is disposed over the reflector and light emitting diodes. In one form, the lens includes a plurality of domes for reflecting at least a portion of the light emitting from the light emitting diodes onto the reflector so as to disperse the light. The reflector includes a plurality of generally conical depressions underlying each lens dome and surrounding a light emitting diode. In another form, apertures are formed in a circumferential wall of the reflector so as to accept light emitting diodes therethrough in an orientation generally perpendicular to the circumferential wall. The reflector includes a central multi-faceted cone having concave depression formed in each facet, and multiple ridges for directing the light to the lens.

摘要： A vehicular lamp having an inner lens is described. In an implementation, an annular wall 18A surrounding an optic axis Ax of a reflector 14 is formed on the inner lens 18 disposed between am outer lens 16 and a reflecting surface 14a of the reflector 14. The inner lens 18 is divided by the annular wall 18A into an internal zone 18B and an external zone 18C which may be different from each other in convex-concave lens shape. The internal zone 18B may be formed of a translucent lens, and a plurality of grid-type lens elements 18Cs may be formed over the entire rear surface of the external zone 18C. Thus, an observer viewing the interior of a lighting chamber from a location in front of the lamp will see that the internal zone 18B and the external zone 18C, which are divided by the annular wall 18A, are significantly different. The configuration of elements provides a vehicular lamp that is visually attractive.

摘要： A lamp unit having a dome-shaped translucent panel disposed in front of several light sources is provided. Opening portions corresponding to certain light sources are formed crosswise in the translucent panel. A condenser lens is provided in the rear of each opening portion in the translucent panel. The dome-shaped portion of the translucent panel is formed as a half-mirror portion, whereby five small cross-shaped translucent domes are visible when the vehicle lamp is in an off state. The light sources positioned to the rear of the opening portions and the light sources positioned to the rear of the half-mirror portions provide an unexpected luminous intensity distribution.

摘要： There is provided a lamp composed of a light source, a tilted ellipsoidal rotation surface reflector, and an annular cylindrical lens. The tilted ellipsoidal rotation surface reflector is formed of an ellipsoidal rotation surface emerging when an ellipsoid, having a first focal line located on the center axis of the light source and adjacent the light source and a second focal point located on an oblique line passing through the first focal point and tilted appropriately from the light-source center axis and assumed on a plane containing the light-source center axis and the oblique line, is rotated around the light-source center axis. The annular cylindrical lens is obtained by rotating, around the light-source center axis, the cross-sectional configuration of an aspheric lens having a focal point adjacent the second focal point of the ellipsoid and having an optical axis nearly parallel to the light-source center axis.
