Abstract
Apparatus for illuminating an object with light that is controlled for intensity and color temperature. A ceiling mounted luminaire contains a circuit that controls the intensity and color temperature of light emitting diodes (LEDs). In one embodiment the circuit is battery powered. A remote unit provides input to the luminaire for controlling the intensity and color temperature of the emitted light. The frequency of a pulse width modulation (PWM) device is varied to control the intensity of an associated LED. The duty cycle or voltage of a pulse width modulation (PWM) device is varied to control the color temperature of an associated LED. In one embodiment a single LED with the desired color temperature range and intensity level is used. In another embodiment multiple LEDs with different color temperature ranges are controlled to provide a mixed output at the desired color temperature and intensity.
