Abstract
The present invention relates to a method for controlling a projector. More particularly, the present invention relates to a method for controlling a projector that enables a projector to operate even when the temperature of the ambient air exceeds a predetermined temperature, and prevents the operation of the projector from being forcibly terminated even when the inside of the projector overheats beyond a predetermined temperature.
Claims20
A method for controlling a projector comprising:
- a temperature measuring step measuring a temperature of a projector;
- a light source part output determining step determining a light source part to be rated-output if the temperature measured in the temperature measuring step is a predetermined temperature or lower and to be attenuated-output if the temperature measured in the temperature measuring step is the predetermined temperature or higher;
- and
- a light source part controlling step controlling the light source part according to the light source part output determined in the light source part output determining step.

A method for controlling a projector comprising:
- a temperature measuring step measuring a temperature of external air drawn into the projector to cool the projector and a temperature of internal air discharged from the projector;
- a light source part and cooling fan output determining step determining output of a light source part and cooling fan, respectively, which are provided in the projector, based on the external air temperature and temperature difference between the internal air temperature and the external air temperature;
- and
- a light source part and cooling fan controlling step controlling the light source part and the cooling fan based on the light source part and cooling fan output determined in the light source part and cooling fan output determining step.
