Typical programmable loads use a pass element such as a transistor to sink a certain amount of power from a target source. The pass element can get very hot and require a heat-sink and active cooling to maintain it within operating temperature. Active cooling solutions can be expensive and require maintenance. This disclosure describes programmable loads constructed out of LEDs. By replacing the pass element with an LED, during the test process, electric energy is converted to light instead of heat. By thus reducing the heat load, thermal management needs for the programmable load are reduced, thus reducing the need for expensive and maintenance-intensive active cooling solutions.
