Abstract
A lighting fixture includes a solid-state light source and control circuitry. The control circuitry is configured to receive one or more ambient light level measurements corresponding to the amount of ambient light detected by an ambient light sensor, and determine a range of values for the one or more ambient light level measurements corresponding to a desired amount of light detected by the ambient light sensor. The control circuitry is then configured to drive the solid-state light source such that the one or more ambient light level measurements received from the ambient light sensor fall within the determined range of values.
Claims58
A lighting fixture comprising:
- a solid-state light source;
- and
- control circuitry configured to:
- receive one or more ambient light level measurements corresponding to the amount of ambient light detected by an ambient light sensor;
- determine a range of values for the one or more ambient light level measurements corresponding with a desired amount of light detected by the ambient light sensor;
- and
- drive the solid-state light source such that the one or more ambient light level measurements falls within the determined range of values.
A lighting fixture comprising:
- a solid-state light source;
- and
- control circuitry configured to:
- receive one or more ambient light level measurements corresponding to the amount of ambient light detected by an ambient light sensor;
- determine a setpoint for the one or more ambient light level measurements corresponding with a desired amount of light detected by the ambient light sensor;
- and
- adjust the determined setpoint for the one or more ambient light level measurements based on a drive signal provided to the solid-state light source.
