Electrical module for multiplexed control of a set of lighting or signalling lamps for a motor vehicle
First Claim
1. An electrical lamp-carrier module for a block of signaling lights for a motor vehicle, said module comprising;
- a lamp-carrier implementing a plurality of recesses used as sockets for a plurality of lamp;
a first multi-pin connector having a plurality of pins respectively connected to each of the lamp sockets via an electrical circuit for selectively and individually powering said lamps, whereby said first multi-pin connector can receive a conventional complementary bundle connector for individually powering the lamps with individual power supply voltages selectively derived from the vehicle battery in a conventional manner;
wherein said module further comprises a separate multiplex-controlled lamp powering unit including;
a second connector for separately receiving a multiplexed lamp control signal containing instructions for turning on and off the respective lamp and a common power line which is permanently connected to said vehicle battery;
an electronic printed circuit board including said second connector and further including a plurality of electronic switching means each associated with one lamp of said plurality of lamps and responsive to said instructions in said control signal for selectively connecting said common power line to said one lamp; and
means for connecting said electronic printed circuit to said first multi-pin connector;
whereby said lamps can be powered either by said conventional bundle connector or by said multiplex-controlled lamp powering unit receiving said control signal and said common power line.

Abstract
An electrical module, in particular for a block of signalling lights for a motor vehicle, comprises, in combination:
a lamp-carrier implementing a plurality of recesses used as sockets for lamps;
an electronic circuit for processing a control and switching signal to selectively switch on and switch off lamps received in the sockets as a function of instructions contained in the control signal;
a printed circuit carrying said electronic circuit;
electrical power link means between the electronic circuit and the sockets; and
means for associating the lamp-carrier with the printed circuit and for establishing an electrical connection between said printed circuit and the electrical power link means.
