Patent ID: 8143793

Claim:
An illumination apparatus comprising: a solid state light emitting device; and a circuit coupled to the solid state light emitting device, the circuit configured to accept alternating current power, wherein the circuit consists of non-switching circuit components configured to alter the alternating current power to generate an output waveform having pulses having a duration in the range of 0.2 to 15 ms at a frequency substantially synchronized with the frequency of the alternating current power and the circuit further consists of a rectifier consisting of passive components, a capacitor, a resistor, a first diode, a second diode, a pair of input terminals configured to allow connection to alternating current power, and a pair of output terminals configured to allow connection to the solid state light emitting device, and wherein the capacitor is arranged in parallel with the output terminals, the resistor is arranged in series with the output terminals and disposed on a load side of the capacitor, and the first and second diodes are arranged in series with the output terminals such that the first diode is disposed on an input side of the capacitor, and the second diode is disposed on the load side of the capacitor.
