and determining the high-pressure gas pressure and speed corresponding to the high-pressure gas, the stable-gear high-pressure gas and the low-gear high-pressure gas of the detachable air source device.
9. The method for dissipating heat of a high power LED light source system as claimed in claim 8, wherein before determining the maximum temperature threshold and the minimum temperature threshold of the LED chips on the LED substrate, the method further comprises:
when the high-power LED light source system is started, the detachable air source device is controlled to output stable high-pressure gas for a first preset time.
10. The method for dissipating heat of a high power LED light source system as claimed in claim 8, wherein before determining the maximum temperature threshold and the minimum temperature threshold of the LED chip on the LED substrate, the method further comprises:
and when the high-power LED light source system is started, the detachable air source device is controlled to output high-gear high-pressure gas for a second preset time and then is adjusted to be stable-gear high-pressure gas.
