Patent attributes
Methods for controlling power consumption and temperature in an LED luminaire are disclosed. The LED luminaire has one or more sets of LED light engines disposed on a printed circuit board (PCB), some or all of which are activated in response to an instruction or set of instructions. The instruction or set of instructions are processed to derive an indication of power consumption for each of the one or more sets of LED light engines. Power allocations for the one or more sets of LED light engines are adjusted to meet targets. This can be done by, e.g., ramping up or down the duty cycle of active sets of LED light engines by a uniform factor until the targets are met. Temperature control methods similarly ramp down the duty cycle of active sets of LED light engines uniformly over time if the measured temperature of the PCB exceeds limits.
