Definitions
- the invention relates to an injection-moulded carrier which can be arranged on body elements and is designed to hold and control light sources, for example to illuminate vehicle interiors and/or console elements.
- the operation of the vehicle should not distract the driver and at the same time require as little attention as possible.
- a driver should be able to blindly perform the functions that can be operated in the vehicle interior.
- blind operation of the vehicle is often no longer possible.
- the vehicle interior is then, as now, a space for individual design, especially at a time when the automobile has become a status symbol.
- the vehicle interior lighting of a vehicle must also meet the wishes of the individual customer. For example, it is common to change the color of individual illuminated elements, such as B. To design decorative strips on the dashboard or on door plates as well as on console elements such as ventilation outlets.

- the injection-molded carrier 100 has a third thermally conductive plastic 123 along the second area 120 .
- the third plastic 123 is between the first electrically insulating plastic 121 and the Lighting modules 131 , 132 , 133 are arranged so that the undersides of the lighting modules 131 , 132 , 133 lie flat on the thermally conductive plastic 123 .
- the thermally conductive plastic 123 also has the openings 124 along the second area 120 of the injection-molded carrier 100 , the thermally conductive plastic 123 transporting away the heat generated by the lighting means 141 , 142 , 143 .
- Fig. 6c shows an injection molded carrier 100 with the third plastic 123 arranged thereon.
- the gateway 152 is arranged for connecting the first area 110 and the second area 120 .
- the lighting module 133 with the lighting means 143 arranged thereon, the lighting module 134 with the lighting means 144 arranged thereon, the lighting module 135 with the lighting means 145 arranged thereon and the lighting module 136 with the lighting means 146 arranged thereon are arranged along the injection-molded carrier 100 .
- FIGS. 7a to 7c show different configurations of the injection-moulded carrier 100, as shown in FIG. 1 shown in various configurations.
- FIG. 7a shows an injection molded carrier 100.
- FIG. The connection of the first area 110 and the second area 120 via the gateway 151 .
- Two lighting modules 132 are arranged along the second area 120 and are coupled to a light band 147 for generating a monochromatic line light.
- FIG. 7b shows an injection molded carrier 100.
- FIG. The connection of the first area 110 and the second area 120 via the gateway 151 .
- the gateway 151 Along the second region 120 are four
- Lighting modules 133 are arranged in such a way that two lighting modules 133 are arranged at one end of a light band 148 in such a way that the light band 148 emits colored linear light.
- FIG. 7c shows an injection-molded carrier 100 analogous to the injection-molded carrier 100 of FIG.
- the lighting modules 135 are with
- Equip illuminants 145 which emit a light field 149 .
