Abstract:

The present disclosure includes an apparatus and method relating to LED fixtures having an LED module capable of operating at a temperature. The LED module is also capable of being operated within a desired temperature range having an upper limit and a lower limit. A fan is operable for cooling the LED module when the temperature of the LED module approaches the upper limit. A heater is operable for heating the LED module when the temperature of the LED module approaches the lower limit. A heat sink may be in thermal communication with the LED module such that the fan may cool and the heater may heat the heat sink. The controller may also be configured to selectively activate the heater and the fan. The controller may also be in electrical communication with a temperature sensor which is in thermal communication with the LED module such that the controller may read the temperature of the LED module. The controller may activate the fan and/or the heater depending on the temperature of the LED module.
