Abstract
A lighting system includes a solid state lighting device capable of generating mixed light and a controller. The solid state lighting device includes light sources for producing mixed light and a sensor configured to detect light from one of the light sources. The controller controls two or more of the light sources based on output from the sensor. The controller can communicate with the sensor to provide closed-loop control.
Claims15
A method for controlling a solid state lighting device having a first light source and a second light source, the method comprising:
- storing temperature compensation data for producing targeted mixed light;
- measuring an intensity of light generated by the first light source;
- selecting at least portion of temperature compensation data corresponding to the measured light intensity;
- and
- controlling the second light source based on the selected portion of temperature compensation data to compensate for temperature effects of the second light source.
A method for controlling a solid state lighting device having a first light source and a second light source, the method comprising:
- measuring an emission of characteristic of light generated by the first light source;
- and
- controlling the second light source to compensate for temperature effects on emissions from the second light source to produce mixed light without any second light source temperature measurements associated with the temperature effects, wherein the mixed light is produced based one or more predetermined correlations between the measured emission of characteristic and the emissions from the second light source.
