The invention relates to a temperature controlled switch testing circuit, which comprises a control module, a counter, a heat producing source and a heat dissipation source, wherein the heat producing source and a temperature controlled switch are connected to two electrodes of a power supply in series, and the temperature controlled switch is located at the position close to the heat producing source and the heat dissipation source; a control end of the control module is connected with the heat dissipation source and the counter simultaneously, and used for controlling the counter to record the on-off times of the temperature controlled switch according to the state that the heat producing source changes along with on-off of the temperature controlled switch. Meanwhile, the control module is further used for controlling the heat dissipation source to carry out heat dissipation on the temperature controlled switch when the temperature controlled switch is switched off. The temperature controlled switch testing circuit shortens the on-off period of the temperature controlled switch, and improves the test efficiency.
Description
technical field [0001] The invention relates to a test tool circuit, in particular to a temperature control switch test circuit. Background technique [0002] During the production of lamps, the life and safety of lamps should be estimated and tested. At present, the most used key component of lamps is the magnetic ballast, which has a temperature control switch to prevent the magnetic ballast from being damaged by excessive temperature. Then, the on-off life of the temperature control switch in the ballast should also be inspected before leaving the factory. Since the on-off of the temperature control switch is disconnected when it reaches a certain temperature value, and then closed when the temperature drops to a certain value, there is a certain difference between the disconnected and closed temperature values, so there are heating and The cooling process, the natural heating and cooling process takes a lot of time, and when testing the on-off life of the temperature c...
