Abstract
A luminaire includes a universal driver control interface to control various types of driver circuits. The luminaire receives, via a voltage divider, an analog voltage feed as a first driver control signal from at least one driver control wire connected to a driver circuit. The luminaire converts, via an analog-to-digital converter, the analog voltage feed into a digital voltage value. The luminaire compares the digital voltage value with a respective range of unique voltage values in a voltage lookup table for each type of driver circuit to determine a respective type of driver circuit protocol. Based on the determined respective driver circuit protocol identifier and a light source control setting, the luminaire outputs a second driver control signal, via the at least one driver control wire, to the driver circuit.
