摘要:
A dual lighting apparatus includes a principal substrate, a first lighting device and a second lighting device. The first lighting device is integrated into a first plane of the principal substrate, the first lighting device having one or more first light emitting diode (LED) chips embedded therein. The second lighting device is integrated into a second plane of the principal substrate, the second lighting device having one or more second light emitting diode (LED) chips embedded therein. The first LED chip(s) emit light photons having a different wavelength than light photons emitted from the second LED chip(s).
摘要:
A casing and a closure plate of transparent, preferably, red color, and comprising one or several light filters provided between the light source and the closure plate, on the one hand, an intensive color impression of the closure plate is attained while the light source is turned off and, on the other hand, the light losses are reduced in that the closure plate is of a continuous coloring, the closure plate is subdivided into segments of varying plate thicknesses and the light filter is provided with recesses.
摘要:
An interim tail light cover has a colored translucent body of red or amber, and snaps onto a taillight when the original lens or colored cover of the tail light has been broken or removed so that the light emitted light retains its red or amber color as is appropriate.

A rear-light assembly for a motor vehicle is positioned at a transition from a rear surface (11) to a side surface (12) of the motor vehicle. A light diffuser thereof (1,2) has an exterior surface which extends relatively smoothly into the rear and side surfaces of the rest of the body of the motor vehicle. Light-diffuser portions (17, 18 and 19) for a brake-light reflector (6), a taillight reflector (7), and a fog taillight reflector (8) are provided with linearly arranged exterior-light reflecting rear-beam prisms (20). In a flat area (18, 19) of the light diffuser, which extends over the fog taillight and taillight, the rear-beam prisms are optically effective while at an adjacent area they are made to be optically ineffective. A light-diffuser portion (15) for a backing light reflector (4) is provided with an opaque lattice, or grill, (21, 22) which includes linearly shaped strips (21). This light-diffuser portion is also in an area of the light diffuser which extends substantially planar, or flat. Optically-ineffective, rear-beam prisms arranged in strips are in light-diffuser portions (16, 24) which are backed by a reflector to the side of the light-diffuser portion for the backing light.
摘要:
A combination lamp in which the lamps forming the combination lamp emit respective red and amber colors as required by applicable official regulations when turned on, but in which the entire combination lamp appears amber when the lamps are turned off, thereby improving the external appearance of the lamp. The combination lamp includes a lamp for emitting red light and a lamp for emitting amber light in which the outer lens of the lamp for emitting red light is colored amber and the inner lens thereof is colored red.
摘要:
A front optical unit for motor vehicles, in which a headlamp is closed by a transparent front body constituted by a lens of glass disposed in front of a rear body of the headlamp, and by a frame of plastics material rigidly connected thereto; the frame surrounds the lens and anchors it to the rear body.
摘要:
A negative photochromic material which is responsive to the ultraviolet portion of the daylight spectrum comprises part of the lens of a light fixture. The material which is of the normally dark type varies the translucence of the lens so that more lumens of light are transmitted through the lens under daylight lighting conditions than at night.
摘要:
A lamp assembly comprises a hollow body having two recesses therein, a bulbholder and a reflector in each recess, and a colorless transparent lens extending across the openings of the recesses. In one of the recesses is mounted a standard bulb and a filter element in the form of a domed cover surrounding the bulb. A neutrally colored light-absorbing material is incorporated into the filter element or is provided as a layer over a surface thereof remote from the bulb.
摘要:
A warning light includes a lens or cover is tinted with a grey or “smoke” tint that is not spectrally selective or alternatively referred to as “neutral density” in that it reduces transmission of all colors of light equally. The objective of the neutral tinted “smoked” lens is to reduce the conspicuity of warning lights when not in use. Ambient light penetration into the warning light is reduced by the proportion of tint and then light reflecting off the optical surfaces within the warning light are reduced again when passing through the tinted lens on the way out of the assembly. The resulting warning light appears dull and is less conspicuous than the same warning light or lightbar with a clear lens. The tinted lens or cover may include optical elements configured to re-direct light, and the entire lens or cover is molded from the same tinted plastic material.
