Abstract
A motor vehicle lighting system includes a master controller, a smart light, and a hot bus. The master controller is electrically couplable to a power supply and is adapted to receive an input signal corresponding to a left turn signal, a right turn signal, a run signal, or a brake signal. The master controller also includes a digital command signal output that is produced in response to the input signal. The smart light includes a light controller and a plurality of light emitting diodes (LED's). The light controller is adapted to control the LED's in response to the command signal. The hot bus electrically couples the master controller to the smart light. Power and the command signal are provided to the smart light over the hot bus.
Claims18
A motor vehicle lighting system comprising:
- a master controller electrically couplable to a power supply and adapted to receive an input signal corresponding to at least one of a left turn signal, a right turn signal, a run signal, or a brake signal, the master controller having a digital command signal output that is produced in response to the input signal;
- a smart light having a light controller and a plurality of light emitting diodes (LED's), the light controller adapted to control the LED's in response to the command signal;
- and
- a hot bus electrically coupling the master controller to the smart light, wherein power and the command signal are provided to the smart light over the hot bus.
A method of controlling a lighting system of a motor vehicle comprising steps of:
- a) receiving an input signal corresponding to at least one of a left turn signal, a right turn signal, a run signal, or a brake signal;
- b) producing a digital command signal in response to the input signal;
- c) providing power and the command signal to a smart light over a hot bus, the smart light having a plurality of light emitting diodes (LED's) and a light controller;
- and
- d) controlling the LED's in response to the command signal using the light controller.
