Abstract
Methods and systems for operating a lighting device are provided. In one example, a method of operating a lighting device including an array of light-emitting elements, an array of heat sinks, and an array of cooling fans, wherein each of the heat sinks corresponds to one of the light-emitting elements, and each of the cooling fans corresponds to one of the heat sinks, includes conductively coupling each of the heat sinks to the corresponding light-emitting element, directing air flow from each of the cooling fans to the corresponding heat sink, measuring heat sink temperatures corresponding to each of the heat sinks with a temperature sensor positioned at the heat sinks, adjusting a speed of each of the cooling fans to reduce a deviation of the corresponding heat sink temperature from a target temperature, and adjusting the target temperature based on an aggregate characteristic of the cooling fan speeds.
