LED Automotive Rear Combination Lamp (RCL) Dual Level Driver Electronics 970652

For the current class of available automotive LEDs (Light Emitting Diodes) used in CHMSLs (Center High Mount Stop Lamps), voltage regulation is required for operation at an optimized output light flux. We have built and measured the performance of resistive, voltage reference, and pulse width modulation DC-DC voltage regulators in order to achieve the required dual level control for RCL (rear combination lamps). These three types of driver electronics for dual level operation of a RCL are compared for performance, and efficiency under various operational conditions.
