Summary of the invention
The purpose of this utility model provides a kind of light sealing current stabilization temperature control integrating sphere, and it realizes effective control to the integrating sphere internal temperature by under the light air-proof condition cold air inside and outside the integrating sphere being carried out convection current under the controllable current stabilization state.
The technical solution adopted in the utility model is: light sealed and can the dustproof air-intake device and go out wind apparatus installing additional respectively on the integrating sphere more than one.
Whole air-intake device and go out wind apparatus and be fastenedly connected on integrating sphere ball wall can be safeguarded, replaceable; Correct position laying temperature detector carries out real-time detection to temperature in the ball in the integrating sphere, can be manually or adjust the size of the gas channel of air vent automatically by adjusting gear; Its workflow of Select the air-intake device of different wind speed and gas flow according to service condition. is: integrating sphere inner light source temperature in the integrating sphere → the unlatchings ventilating system of starting working → measure makes the inside and outside hot cold air of integrating sphere carry out temperature in convection current → measurements integrating sphere → adjusting ventilating system to make the interior temperature of integrating sphere reach the interior temperature of setting operating temperature → measurement integrating sphere → adjusting ventilating system to make cold and hot convection current air current stabilization and make whole integration sphere light source system and external environment keep thermal balance → dynamic real-time monitor → light source power cut-off → close ventilating system under the temperature constant in ball.
Compare with traditional integrating sphere, light sealing current stabilization temperature control integrating sphere is keeping under the constant situation of integrating sphere original function, solved the temperature control problem of integration effectively, realized to temperature in the traditional quadrature ball ball effectively, control in real time, for realize accurately, stable, reliable, can repeat, controllable high precision ray radiation measurement provides sound assurance.
