Indicating light, in particular a complementary stop light for a motor vehicle, having a number of light sources in line with each other
First Claim
1. An indicator unit for a motor vehicle, comprising a housing defining a front of the unit, a plurality of light sources within the housing, each light source defining a given emission field in which that light source emits light and a redirecting member in the housing defining a general emission direction towards the front of the unit, the redirecting member redirecting the light emitted by the sources towards the front of the unit, wherein the redirecting member comprises lenses and a cylindrical mirror disposed optically between the light sources and the lenses, wherein each of the lenses is focused in a region of the emission field of each of the respective light sources and wherein the mirror reflects the light emitted by the light sources in at least an edge portion of their emission field.

Abstract
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.

11. An indicator unit for a motor vehicle, comprising a housing defining a front of the unit, a printed circuit within the housing, a plurality of light sources, mounting means mounting the light sources in general alignment with each other within the housing, each light source defining a given emission field in which that light source emits light and redirecting means in the housing, the redirecting means defining a general emission direction towards the front of the unit, the redirecting means redirecting the light emitted by the light sources towards the general emission direction and an optic disposed in front of the redirecting means and having optical elements for diffusing the light received from the redirecting means, wherein the redirecting means comprises lenses focused in a region of the respective light sources in a central part of their emission field, the redirecting means further comprising a cylindrical mirror disposed optically between the light sources and the lenses, the mirror for reflecting towards the lenses the light emitted by the light sources in at least an edge portion of their emission field, wherein the mirror has a flat base, the mounting means including spacers mounting the mirror in the housing, the spacers being attached to the flat base of the mirror, and wherein the light sources and the mirror are connected to the printed circuit.
