Problems solved by technology

A disadvantage of this additional brake light is that relatively high positional tolerances occur in the positioning of the structural units arranged at a distance from one another, namely the light source on the one hand, the optical element and the hologram element on the other hand.

Embodiment Construction

[0027] According to figure 1 In a first embodiment of an additional brake light for a vehicle, the additional brake light is arranged as a high-mounted brake light in the rear region of the roof lining 1 of the vehicle. The additional brake light has a housing 2 which is usually fastened between the wall of the roof lining 1 of the vehicle and the rear window 3 . The housing 2 is elongated in the transverse direction of the vehicle. The housing has a narrow side 4 extending in the transverse direction of the vehicle and opposite long sides 5 , 5 ′ adjoining the narrow side at right angles. The upper long side 5' is formed in sections. The first section 6 , which adjoins the narrow side 4 preferably at right angles, is connected in one piece with the narrow side 4 and is made of an opaque or opaque material. The second section 7 of the upper long side 5 ′, which adjoins opposite to the direction of travel F of the vehicle, adjoins the first section 6 at an acute angle and es...

Abstract

The invention relates to an auxiliary stop lamp for vehicles, in particular high-mounted stop lamps for vehicles, having a light source (10, 10') for projecting a light beam, and a holographic element (13, 13') for refracting and / or reflecting the light beam, wherein the holographic element (13, 13') comprises holographic light spreading means for providing a stop light function, and the holographic element is arranged inside and / or in the region of an edge of a housing (2, 2') of the auxiliary stop lamp or is designed as an edge of the housing (2, 2') of the auxiliary stop lamp.

Description

technical field [0001] The invention relates to an additional brake light for a vehicle, in particular a brake light for a vehicle mounted on height, comprising a light source for emitting a light beam and a hologram element for diffracting and / or reflecting the light beam, wherein, The hologram element has a holographic light distribution for generating the brake light function. Background technique [0002] An additional brake light for vehicles is known from US Pat. No. 5,347,435 A, which is arranged in a cavity between the ceiling panel and the roof of the vehicle. The light source and reflector are provided in a cast metal housing positioned in the cavity. A holographic element for refracting the light beam is arranged on the rear window arranged in front of the light source in the direction of emission, so that a predetermined additional brake light function can be produced. Disadvantages in the known supplementary brake lights are the complex construction with diffe...
