Abstract:
The invention relates to a high-intensity discharge lamp for a vehicle-light projector system, comprising a base (4) that carries an outer envelope (1) in which a burner (2) is arranged, the burner (2) comprising a discharge chamber (21) into which two electrodes (22, 23) project, the discharge chamber (21) being filled at least with an inert gas, a mixture of metal halides and a salt reservoir, the so-called 'salt lake' (25). The outer envelope (1) has a coating (31) in strip form that screens off light and that extends, on the side of the outer envelope (1) adjacent the salt lake (25), for at least 40 % of the length of the outer envelope (1) and whose width covers an angle of between 90° and 180° around the outer envelope (1). The invention also relates to a projector system for motor vehicle headlamps comprising at least one high- intensity discharge lamp of this kind.
Abstract:
The invention relates to a lamp for a vehicle headlight featuring a dimmed function. Said lamp comprises an outer bulb (3) and a light-emitting zone (4) and emits at least visible light having different colors from several areas of the outer bulb (3). At least one partial coating (2) is disposed on the outer bulb in such a way that the region of the traffic space located below the light-dark threshold (F) can be illuminated with visible light having different colors in defined zones when the headlights are dimmed.
Abstract:
The invention relates to an LED light system (1) for generating directed illumination radiation. The system comprises a plurality of LED lamp elements (2), each comprising a collimator (10) with an LED element (9). The LED lamp elements (2) are arranged in a defined array for generating a specified luminance pattern. A secondary optics device (11) images the luminance pattern in the space to be illuminated.
Abstract:
A lamp (10, 11) for a motor vehicle headlight is described. The lamp (10, 11) comprises a quartz bulb (3, 12, 17) narrowly enclosing a light source (1, 2) and possibly an outer bulb (4) surrounding said quartz bulb (3). Negative lenses (7, 8, 14, 15, 16) extending in the direction of a longitudinal axis (L) of the lamp (10, 11) are present in or at the two lateral surfaces (6, 13) of the quartz bulb (12, 17) and/or of the outer bulb (4). These lenses (7, 8, 14, 15, 16) are designed such that the light source (1, 2) is optically reduced in size in at least one direction.
Abstract:
The invention relates to a lamp for a vehicle headlight with low-beam function, which lamp has an outer envelope (4) and emits at least visible light of different colors from several regions of the outer envelope (4), characterized in that in that a partial coating (2) is at least provided on the outer envelope (4) such that, when the low-beam function is being realized, at least that region of the traffic space which lies above the bright-dark cut-off can be at least partly illuminated with visible colored light which is scattered at said partial coating (2), while at the same time that region of the traffic space which lies below the bright-dark cut-off can be illuminated with visible light of a different color in defined regions.
Abstract:
The present invention relates to an electric lamp (1) for vehicle headlights with low-beam function comprising a light source (2) emitting visible light (4), a transparent envelope (3) having an exterior surface (3 ') and an interior surface (3'') enclosing said light source (2), at least one multilayer structure (7) provided on the exterior surface (3') of the envelope (3), wherein a first light (5) substantially with a bluish- white color transmits the multilayer structure (7) directly and a second light (6) substantially with a yellowish color transmits the multilayer structure (7) after being reflected at the multilayer structure (7), wherein the multilayer structure (7) being of none light absorbing materials is provided in such a way, that the color of light of a standard light source A being reflected at the multilayer structure (7) lies within a triangle in the CIE 1931 Yxy color space defined by the x, y coordinates (0.58; 0.42), (0.58; 0.30) and (0.70; 0.30) wherein the lightness Y is in the range of 2.5 = Y = 17.5, wherein none of the emitted visible light (4) is absorbed by the multilayer structure (7).
Abstract:
The invention relates to a lamp with one filament for a vehicle headlamp with a low beam, fog light, turning light or bending light function, which comprises at least an outer tube (3) and a light-emitting region (4) and which emits at least visible light from a number of regions of the outer tube (3), wherein at least one partial coating (2) is arranged on the outer tube (3) in such a way that, when the low beam, fog light, turning light or bending light function is implemented, the area of the traffic space which lies below the light/dark cut-off (F) can be illuminated in a first defined region with increased intensity and in a second defined region with reduced intensity and the partial coating (2) is an at least partially reflective coating.
Abstract:
A lamp (1, 11, 14, 17) for a motor vehicle headlight is described. The lamp (1, 11, 14, 17) comprises a bulb (3) surrounding a light source (4) and a lamp base (2) arranged at an end of the bulb (3) and serving to support the lamp (1, 11, 14, 17) inside a reflector (20) of the headlight. At least one lens structure (7, 12, 15, 18) is present in or at an upper side (O) and/or lower side (U) of the bulb (3). This lens structure (6, 12, 15, 18) is constructed such that at least a portion of the light radiated by the light source (4) in the direction of a region of the reflector (20) close to the lamp base is redirected into a region of the reflector lying farther to the front.
