Abstract
A light system and method includes a housing having an array of LEDs spaced to transmit light within a field of illumination. An EM sensor disposed within the housing is configured to detect EM radiation within the field of illumination. A processor is configured to generate an output in response to levels of EM radiation, such as visible light, infrared light, and/or radio frequency (RF) radiation detected by the EM sensor relative to a predetermined setpoint.
Claims46
A light system comprising:
- a housing;
- a plurality of LEDs disposed in spaced relation within the housing and configured to transmit light within a field of illumination;
- a power source configured to supply operational power to the LEDs;
- an optical sensor disposed within the housing, and configured to detect ambient light levels within the field of illumination of the LEDs;
- a dimmer operatively engaged with the power source;
- a processor communicably coupled to the dimmer and the optical sensor, the processor configured to actuate the dimmer to adjust power supplied to the LEDs in response to levels of light detected by the optical sensor relative to a predetermined setpoint;
- a packet-based communications module operatively engaged with the processor, and configured to receive from a remote location, adjustments to the predetermined setpoint;
- a thermostat disposed within the housing;
- a thermal switch disposed within the housing;
- a cooling fan disposed within the housing to move cooling air to the LEDs in response to actuation of the thermal switch;
- at least one vent disposed within the housing;
- at least one baffle disposed to alternately open and close the vent to alternately direct cooling air from the LEDs towards locations on opposite sides (e.g., above and below) the housing;
- an actuator operatively engaged with the baffle, and configured to open and close the vents in response to the thermostat;
- and
- a speaker driver disposed within the housing to enable the light system to function as a loudspeaker.
