PROJECTION DEVICE HAVING BLOWER AND/OR LAMP WITH FEEDBACK CONTROL |
摘要 |
In one example, a method for controlling temperature in a projection device, comprises measuring a plurality of temperatures in the projection device; averaging said plurality of temperatures to determine an averaged temperature; determining an error between a set-point temperature and said averaged temperature; and automatically adjusting a blower in said projection device based on said determined error. In another example, a method for controlling temperature in a projection device having a lamp and a blower comprises measuring temperature in the projection device; and selectively adjusting both a first signal to the blower and a second signal to the lamp based on said measured temperature to control temperature in the device. |
