Abstract: An LED stabilizing light source device comprises an LED, a drive circuit for driving the LED, a wavelength filter for filtering the light emitted from the LED, a light splitter for splitting the light passing through the filter, a photodiode for receiving the split light. The device further comprises a feedback loop for feeding an output of the photodiode to the drive circuit.
