Problems solved by technology

[0005] The operating temperature control of the projector is an important condition to ensure the service life and normal operation of the projector. In related technologies, the fan can only dissipate heat at the same speed to control the operating temperature of the projector. , the service life of the filter screen of the projector is much longer than that under the condition of low cleanliness
[0006] However, because projectors can only conservatively set the filter life and replacement time, it causes a lot of waste

Abstract

Provided are a light source system, and a projector (100) and a temperature controlling method thereof. The light source system comprises a fan (2), a light source (3), an air admission channel (4), a filter screen (5) engaging the air admission channel (4), an ambient temperature sensor (6), an operating temperature sensor (7), and a processor (8). The ambient temperature sensor (6) is used to detect an ambient temperature outside the light source system. The operating temperature sensor (7) is used to detect an operating temperature inside the light source system. The processor (8) receives the ambient temperature and the operating temperature, determines and compares the same, and adjusts, according to a result of determination and comparison, a rotation speed of the fan (2) and / or an output power of the light source (3). The light source system can accurately adjust an amount of air admitted to the projector (100) to extend service life of the filter screen (5), and can determine a degree of clogging of the filter screen (5), thereby improving operating performance of the projector (100).

Description

technical field [0001] The invention belongs to the field of light source technology, and in particular relates to a light source system, a projector and a temperature control method. Background technique [0002] At present, projection technology is widely used in people's daily life. The use of projection systems can be seen everywhere in conferences, teaching or entertainment venues. [0003] In the related art, small and medium-sized projectors for home and education usually use fan air cooling to guide the airflow through the air duct inside the projector, and take away a large amount of heat generated by the light source and LCD screen when working, thereby protecting the normal operation of the projector. . In order to ensure that no dust is brought in when the air is introduced to affect the image quality, an air filter needs to be installed at the air inlet. [0004] The service life of the air filter is closely related to the use environment. After a long perio...
