A taillight system for an automotive vehicle has an optic manifold mounted in a assembly defining a light emitting area, a first light source configured to provide illumination through the light emitting area, and a second light source configured to provide illumination through a predetermined portion of the light emitting area. The system has an illumination mode in which the first light source provides illumination of a first intensity in a first wavelength range through the light emitting area, a brake mode in which the first light source provides illumination of a second intensity in the first wavelength range through the light emitting area, and a backup mode in which the second light source provides illumination in a second wavelength range through the predetermined portion of the light emitting area, with or without the first light source providing illumination through the light emitting area, the second wavelength range including the first wavelength range.

A highly efficient luminaire. The luminaire includes a light source that emits light. The emitted light is redirected by a light transformer having a curved circular reflective interior surface, the reflective interior surface reflecting the light in a predetermined pattern. A substantial amount of light being may be reflected close to an axis coincident with a radial line defining a radius of the circular reflective interior surface. Additionally, a substantial amount of light may be reflected in a pattern with low divergency or parallel with an axis of the light transformer. The light is transmitted to the exterior of the luminaire by an optical window.

A vehicle lamp unit 1 in which a plurality of light emitting diodes 13 are arranged to make up a light source is disclosed. The lamp unit includes a base member 7 for supporting a plurality of the light emitting diodes, feeder wires 14 that are disposed at the reverse side of the base member and connected to lead terminals 13 d of the light emitting diodes, and feeder terminals 16 connected to the feeder wires. The lamp unit advantageously realizes a cost reduction, enhances the degree of design freedom, and promotes environmental protection.

Vehicle lamp unit

A light module including a single light emitting diode (LED) and a rotationally symmetrical reflective light transformer providing an omnidirectional pattern with a pre-calculated intensity distribution. In alternative embodiments the light module may consist of a plurality of LEDs and the reflective light transformer, having plurality of identical segments, provides an omnidirectional pattern with a pre-calculated intensity distribution as a result of superposition of the limited angle pattern reflected by each segment. In order to provide high efficiency the light transformer reflective surface profile is designed using a given LED's spatial intensity distribution and required intensity distribution across the emitted omnidirectional pattern as a design parameters.

Led light module for omnidirectional luminaire

A light fixture has a reflector having a part-elliptical surface and having at least one focal point at which is provided an LED set behind a main shield that prevents light from passing directly out of the light through a light-output plane. The reflector surface is shaped as an ellipse outside the apex point and adjacent the one focal point of the ellipse at which the LED is located. An arcuate portion of the ellipse segment defines the light-output plane, and the reflector surface extends along a longitudinal straight line. The LED, a straight longitudinally extending free edge of the main shield, and a straight longitudinally extending free edge of the reflector surface or a longitudinally extending straight edge of a secondary shield positioned generally at the outer free edge of the reflector surface lie in a common plane.

Reflector-type light fixture

The brake lights have several light sources (30) in a housing under a parabolic mirror (22d) which reflects the light through a collimating lens (40) and out of the brake light housing in a preset angle The mirror is divided by two planes (P1,P2) to define the light beam The light sources, LEDs etc are mounted in the lower recess with the mirror having a number of parabolic sections in a horizontal array The output section of the housing has a steeply sloped lens (5a) corresponding to the slope of the rear windscreen of the vehicle

Rear brake light for motor vehicle

The lamp includes a low-profile housing which encloses a dozen generally aligned light sources (preferably LEDs) (20) spaced 25 mm apart on an elongated printed circuit board. Emission from each hemispherical end (22) is concentrated by a cylindro-parabolic reflector (40) through the Fresnel lens (50) on to an array of scattering spheres or toroids (61) on the inside of a U-section moulding (60). The body (21) of each source is wider than the emissive hemisphere on to which the reflector and facets (51) of the Fresnel lens are focused. The hemisphere emits into a cone with a semi-vertical angle (θ ) of about 50 degrees , while the reflector restricts the angle of emission (phi) to 30-40 degrees .

Signal light with several light sources arranged in line, especially complementary brake light for vehicle

An indicator unit for a motor vehicle, in particular a so-called complementary rear stop light displaying a narrow strip of light, has a plurality of light sources aligned with each other in an elongate narrow housing. Each light source emits light in a given emission field. The unit includes optical means for redirecting the light emitted by the sources in a general emission direction, and an optic having optical elements for diffusing the output light of the unit. The redirecting means comprise lenses focussed in the vicinity of the respective light sources and directly exposed to the radiation emitted by the respective sources in a central part of their emission field, together with a cylindrical mirror which reflects towards the lenses the light emitted by the sources in at least an edge portion of their emission field.

Indicating light, in particular a complementary stop light for a motor vehicle, having a number of light sources in line with each other

An indicating display for a motor vehicle, for example a raised stop light unit, includes a plurality of aligned light sources, optical means for concentrating the luminous flux emitted by the light sources in a general emission direction, and a lens which is provided with optical means for diffusing the light. The optical concentrating means consist of a parabolic mirror which is bounded by two planes both of which lie on the same side of its optical axis, and which are in line with the lens, while the light sources are offset vertically from the lens.
