Abstract
The present disclosure generally relates to apparatus and methods for controlling ventilation and temperature around a light source. A ventilation and temperature control assembly configured to selectively facilitate air circulation in an enclosure around a light source is disclosed. In some embodiments, a temperature sensor may be disposed near the light source. The air circulation may be switched on and off according to temperature measurement of the temperature sensor. In some embodiments, the ventilation and temperature control assembly includes a valve to selectively open and close a flow path in the ventilation and temperature control assembly.
