1. A control circuit for a lighting device, comprising:

  • Light Emitting Diodes (LEDs);

    a rectifier circuit for converting an Alternating Current (AC) power source into a Direct Current (DC) power source;

    a power conditioning circuit coupled across the rectifier circuit and configured to condition the DC power source;

    a controller configured to monitor an analog reference signal corresponding with the DC power source and generate pulses according to the reference signal that enable current from the DC power source to activate the LEDs; and

    a dimmer circuit configured to reduce the analog reference signal and cause the controller to reduce a duty cycle of the generated pulses that reduce an amount of light generated by the LEDs.
