Abstract
A method for determining whether to activate an illumination source includes directing an air current across at least a portion of the illumination source and across at least a portion of a temperature sensor. The method also includes sensing the temperature of the air current with the temperature sensor and determining whether to activate the illumination source based on the temperature of the air current.
