The invention discloses a circuit used for testing service life of a temperature controlled switch of a ballast. The circuit used for testing service life of the temperature controlled switch of the ballast comprises a direct current power module, a counter, a first relay K1, a second relay K2, an optical coupling tube and a switch tube Q1. The first relay K1, the second relay K2, the optical coupling tube and the switch tube Q1 monitor on-off state of the temperature controlled switch of the ballast, and controls the counter to count once when the temperature controlled switch is detected in an off state. In addition, the counter is further connected with a buzzer. When the counter completes counting, the buzzer alarms to warn a work staff. With adoption of the circuit used for testing service life of the temperature controlled switch of the ballast, the work staff does not need to guard aside a test circuit in the whole process to record on-off times of the temperature controlled switch when the service life of the temperature controlled switch of the ballast is tested, and work efficiency is improved.
Description
technical field [0001] The invention relates to the field of quality detection of lamps, in particular to a circuit for testing the service life of a temperature control switch in a ballast. Background technique [0002] As a necessity of life, lamps and lanterns are closely related to people's life. In order to ensure that the factory-made lamps are all qualified products, it is necessary to carry out various quality inspections and tests on the lamps after the production of the lamps is completed. One of the main tests is to detect the life of the temperature control switch in the lamp ballast. Testing the life of the temperature control switch refers to testing whether the temperature control switch is still effective under the specified number of on and off. [0003] Generally, the temperature control switch is turned off when the ambient temperature is higher than its temperature threshold value, and closed when it is lower than another temperature threshold value.
