Lighting or indicating light unit for a vehicle and lighting or indicating system equipped with at least one such light unit
First Claim
1. Lighting or indicating light unit for a vehicle, of the type comprising a shell containing lighting or indicating means and possibly ancillary facility means for implementing ancillary facilities such as light beam adaptation or automatic adjustment of the orientation of the light beam, wherein, mechanically associated with its shell, it includes an electronics card including:
- a supply connector to an electrical power supply device;
a standard connector, whatever ancillary facilities are activated on the light unit, the said standard connector being intended to be linked to the multiplexed bus of an on-board network;
control means for controlling the lighting or indicating means and possibly the ancillary facility means, the said control means being connected to the said supply connector and to the said standard connector in such a way as to allow commands and information on the status of the light unit to be exchanged over the multiplexed bus;
an internal bus connected, on the one hand, to the control means and, on the other hand, to the lighting or indicating means and to the ancillary facility means for exchange between them of commands generated by the control means and of information on the status of the light unit.

Abstract
The present invention relates to a lighting or indicating light unit for a vehicle. It also relates to a lighting or indicating system equipped with at least one such light unit. It extends directly to indicating devices, such as vehicle lights but also to other similar products such as reversing radars and other systems.
The light unit of the invention includes lighting means and ancillary facility means as known. According to the invention, the light unit incorporates an electronics card, which is connected, on the one hand, to a controller for a multiplexed bus by a harness and, on the other hand, to a source of electrical supply by a harness. It includes an integrated controller, which performs all the functions associated with controlling the lighting means and the ancillary facility means, whatever the type of light unit involved.
Among the advantages of the invention is the reduction in the length of the cabling harness of the onboard network and the reduction in the electromagnetic emissions.
