Abstract
A temperature control module and a temperature control method, which are suitable for a projector. A thermal sensor is disposed on the projector and suitable for sensing the ambient temperature to generate an ambient temperature sensing signal. A cooling device is disposed on the projector and suitable for cooling a target element of the projector. When the projector is in a brightness adjustment mode, a control circuit generates a control signal to the cooling device according to the ambient temperature sensing signal from the thermal sensor and the brightness setting signal of the projector. The cooling device adjusts the temperature regulation operation performed on the target element according to the control signal.
