Abstract
A lamp in which a LED array is coupled to a transistor such that the same amount of current flows through both. The voltage level at the control (e.g., base) terminal of the transistor is controlled such that the current magnitude is reduced when the operating temperature rises. As a result, the heat generated from the junctions of the LEDs in the LED arrays is reduced, thereby compensating for the increase in the operating temperature.
