Problems solved by technology

The heat sink usually consists of heavy metals, precious metals, so that this poor efficiency is also accompanied by an undesirably high weight and undesirably high costs
[0008] Furthermore, the known solutions with prismatic separating elements have the disadvantage that different areas of the light guide show different brightness and have a stained appearance in side view
Therefore, the overall high cost
Another disadvantage is that, instead of the ideal appearance of the lighting strip, discretely distributed lighting points are produced

Embodiment Construction

[0046] figure 1 The motor vehicle lighting device 10 is shown in detail in the front view with a housing 12 and a light output opening which is covered by a transparent dust cover 14 . Behind the dust cover 14 is an optical module 16 disposed inside the casing 12 . The optical module 16 has a longitudinally elongated light guide 18 with a figure 1 Slot-shaped reflector 20 located behind light guide 18 in the line of sight direction in the front view of . In the exemplary embodiment shown, the lighting device 10 is a daytime running light, a separate flashing light, a high-mounted brake light or a light that fulfills another signaling function. In an alternative configuration, the light module 16 can also be integrated into the headlight with the headlight function. In this regard, the lighting device according to the invention may be a headlamp or a luminaire. Headlamps are used to illuminate the roadway or unlit objects on the roadway, while lamps have the function of ale...

Abstract

Provided is a motor vehicle lighting device (10) with a light module (16) which is used to produce a band-shaped light-emitting surface and has an elongated photoconductor (22) displayed as longitudinal. The photoconductor is provided with a plurality of discrete elements (24) arranged in rows along the longitudinal direction (x) of the photoconductor (22). The motor vehicle lighting device (10) is characterized in that the light module (16) is provided with trough-shaped reflectors (20, 38) which extend in the longitudinal direction (x) of the photoconductor (22) and are illuminated by the discrete elements (24) in rows, wherein most illuminated points of the reflectors (20, 38) by the extraction elements (24) are illuminated by more than one discrete elements (24).

Description

technical field [0001] The invention relates to a motor vehicle lighting device with a light module for producing a strip-shaped illumination area and having an elongated light guide shown in longitudinal direction with rows along the longitudinal direction x of the light guide Set of multiple separated elements. Background technique [0002] Such motor vehicle lighting devices are known per se. The light module is used to realize light functions such as daytime running lights, tail lights, flashing lights, positioning lights, etc., and the light module is used as a separate lighting unit, for example in the exterior rearview mirror or on the fender Additional flashing lights, high-mounted brake lights or separate daytime running lights, or the light module is used as a light module integrated in the headlight and / or rear light. For design reasons, it is often desirable here for the strip-shaped illuminated surface to run three-dimensionally curved in space. As an example...
