摘要: An LED-based luminaire is configured to direct light from an LED source downwardly. However, a portion of the luminaire intentially reflects part of the light upwardly toward a ceiling of a structure. A control circuit of an LED-based luminaire enables the luminaire to be dimmed by an off-the-shelf dimmer. The control circuit also determines when a temperature of the LED-based luminaire exceeds a desired temperature range, and employs a feedback circuit to reduce power delivery to the LEDs until the temperature is again within the desired temperature range.
