An incandescent lamp for a vehicle headlight comprising a transparent vessel that encloses at least one filament and the vessel is at least partly covered with a coating. The coating comprises at least one pigment, which is arranged such that light emitted by the at least one filament and traversing the coating is transformed to transformed light. The transformed light is characterized by a chromaticity according to the CIE 1931 xy-chromaticity with y being in between the Planckian locus and y=0.5*x+0.205 and 0.36<x<0.42, and wherein the at least one pigment comprises a mixture of CoAl oxide and CoAlCr oxide, the mixture being characterized by a ratio of a concentration in mass percentage Cm(CoAl oxide) of CoAl oxide and a concentration in mass percentage Cm(CoAlCr oxide) of CoAlCr oxide in the coating of 90/10Cm(CoAl oxide)/Cm(CoAlCr oxide)30/70.

An illumination device for a vehicle includes a reflector having a rear-side lamp opening and a protective collar formed around the lamp opening. The protective collar has an inner diameter and has a cut-out of a peripheral segment. A lamp has a lamp axis and is configured to be received in the lamp opening by an introduction movement in a direction of the lamp axis and a rotary movement about the lamp axis. The rotary movement of the lamp about the lamp axis defines a rotational space of the lamp. An electrical contact plug element is configured to connect to the lamp. The inner diameter is slightly larger than the rotational space defined by the lamp. The cut-out of the protective collar is configured to receive the plug element such that the plug element is disposed through the cutout peripheral segment when connected to the lamp.

A vehicle lamp includes: a light source unit including at least one light source configured to generate light; a lens that is arranged closer to a front of the vehicle lamp as compared to the light source unit, the lens configured to transmit the light generated by the light source unit; and a shield that is arranged between the light source unit and the lens, and configured to receive the light generated by the light source and allow at least a portion of the received light to pass therethrough, wherein the shield includes a plurality of pixels having respective light transmittances that are configured to be variably controlled, and wherein each of the plurality of pixels is configured to allow independent control of respective light transmittances.

A partially coated lamp capsule (212) for a projection headlamp (12) has filament (224) in capsule envelope (220) having light-transmissive coating (60) extending from capsule upper region (225) towards filament distal end (227) to an axial location in a region defined between about 0.098 inch (2.5 mm) above filament distal end (227) and about 0.098 inch below filament distal end (227), the capsule envelope (220) being uncoated on an undistorted portion of capsule envelope (220) below filament proximal end (229). Lamp capsule (212) is useful in projection headlamp (12) having a reflector (28) whose central heel (37) forms the hot spot and casts light through projector lens (30) to generate low and/or high beam patterns. Present lamp capsules (212) give increased photometric intensity over conventional lamps in low beam at critical driver's lane (0.6D, 1.3R) and (0.86D, V) test points, and in high beam at the critical (H,V) test point.

A headlight housing assembly for mounting a projector lamp. The headlight housing eliminates the need to cut a stock headlight housing of a motor vehicle for an aftermarket adaptation to receive a projector lamp. The invention permits installation of a properly aligned projector, mounted securely to the vehicle, with no mess created. The design results in a professional looking product using stronger materials for a longer expected life.

A bi-functional headlamp for a vehicle is provided. The bi-functional headlamp implements a high beam mode and a low beam mode by adjusting a movement of a shield of a headlamp. The bi-functional headlamp reduces the occurrence of impact and noise caused by an operation of opening and closing the rotary shield by maintaining contact between a shock absorber component that reduces operational noise of the rotary shield and one side of the rotary shield.
