Zusammenfassung: | This disclosure describes techniques to control LED lighting systems using a circuit that includes communication, control and LED driver circuitry specific to a limited number of particular lighting functions. The circuit may communicate via a standard communication bus protocol and include feedback, protection and sensing circuitry to monitor the lighting functions and LED performance. The circuit may be small enough to be included as part of a lighting assembly, such as a vehicle headlight assembly. The included feedback and monitoring circuitry that may be physically close the driven LEDs may simplify the wiring when compared to other techniques. A configuration process for the circuit may further simplify the wiring connections, as well as reduce the development and manufacturing costs for lighting systems that may use the circuit. Limiting the lighting functions of each circuit may improve thermal management by distributing the thermal load. |
