摘要:
In a color changing lamp equipped with a bulb 4 emitting a color of light, a glove with a different color from the color is selectively located on the covering position and exposure position of the bulb 4 in order to emit the different color of light. The current supply for the bulb 4 is stopped while the glove is selectively moved, thereby preventing different colors of light in a mixed state from being emitted on the way of exchange.

A vehicle lighting system includes one or more central light sources, a plurality of optical loads including headlight lenses, an optical fiber network that extends from the light sources to illuminate the headlight lenses and other optical loads, and optical switches and oscillators that include respective input fibers illuminated from the light source and output fibers to respective optical loads, and operate by enabling and disabling optical connections between their input and output fibers. The headlight assemblies switch between high and low beams by moving their fibers vertically, and control beam diffusion by moving the fibers parallel to the lens axes, including an automatic diffusion adjustment for a headlight reflection from a vehicle in front. The switches include various mechanisms for moving the input and output fibers into and out of alignment with each other, including a shaped resilient sleeve, a hinge pivotally joining the fibers, an opaque shutter with a transmissive section movable between the fibers, and also a liquid-based switch that relies upon total internal reflection. A feedback mechanism for some of the switches dims the source lamp when the switch is OFF to conserve energy. The oscillators operate by normally urging an input fiber towards an OFF position, at which it actuates a mechanism that shifts it to an ON position at which the mechanism is deactivated. A failsafe system employs multiple light sources, with each source sharing its light output with the load for another source that has failed.
摘要:
A motor vehicle headlight of the type comprising a single light source, a reflector including two zones suitable for generating two different respective light beams, a closure glass, and masking means situated in the vicinity of the source and capable of being displaced for selectively masking the light rays delivered by the source and propagating towards at least one of the two zones. According to the invention the two zones of the reflector are disposed side by side, each of them extending over the entire height of the reflector, each zone of the reflector is constituted by a portion of a reflecting surface sufficing on its own to generate the associated beam, and the masking means comprise at least one screen which, in its masking position, is situated to one side of the source.

A lamp for a vehicle includes a light-emitting unit including a light source and a reflector, a shield unit to form a beam pattern by blocking at least some of the light generated by the light-emitting unit, and a lens unit disposed at the front of the shield unit. The shield unit includes a first shield, which forms a first region of the shield unit, and a second shield, which is driven to cover or uncover a second region of the shield unit. The lamp, with a simpler structure, can form various beam patterns while sufficiently securing a driver's field of view.

A multi-function headlamp, in particular for a motor vehicle, is arranged to improve the illumination of road signs and other external objects. It includes an occulting means for defining a cut-off line for a beam such as a dipped beam or fog penetrating beam, lamp means of the kind that emits both visible light and ultra violet radiation simultaneously, and a front closure glass of a material which is at least partially transparent to ultra violet radiation. The occulting means is also opaque to visible light radiation and at least partially transparent to ultra violet radiation, and the occulting means is mounted for displacement between an occulting position, in which it intercepts all visible radiation directed above the cut-off line, and a retracted position in which it has substantially no effect on the transmission of visible light radiation.
