Abstract:
1. A regulated power supply assembly for providing variable DC voltage to a parallel, series or combination thereof light emitting diode (LED) array comprising: a) an analog or microcontroller feedback module which receives one or more feedback signals from at least one feedback signal generator connected to the LED array and delivers a scaled voltage based on comparing the one or more feedback signals with predetermined array operating conditions for those feedback signals wherein a plurality of signal conditioners scale the feedback signals input to the feedback module; b) a synchronous buck-boost converter which receives the scaled voltage from the feedback module and delivers voltage to the LED array whose voltage amplitude is based on the scaled voltage received from the feedback module; c) a low pass filter between the synchronous buck-boost converter module output and the LED array; and d) a power source for powering the assembly.
