Abstract

The invention belongs to the product detection and test field and provides a switch starting life test circuit which is suitable for a lamp. The switch starting life test circuit comprises a timekeeping control unit, a timing control unit, a first switch unit and a second switch unit. The timekeeping control unit controls the first switch unit so as to control starting or closing of the timing control unit or accelerate electricity work time of a life circuit of a tested product. The timing control unit controls the second switch unit so as to control starting or closing of a driving board to be tested. In the circuit, the timekeeping control unit is used to set and accelerate the electricity work time of the life circuit of the tested product and the timing control unit is used to set conduction time and power-off time of the driving board to be tested so as to achieve a circuit which can automatically control and detect a product life. A manual test is not needed. A manual workload is reduced and test efficiency and accuracy of test data are guaranteed.

Description

technical field [0001] The invention belongs to the field of product detection and testing, in particular to the field of product accelerated life testing. Background technique [0002] In today's society with the development of science and technology, the high stability of products is a common goal pursued by manufacturers, sellers and product users. Taking lighting products as an example, as a new type of energy-saving and environmentally friendly LED light source, there are more and more applications. In this way, not only the life of the LED needs to meet the use requirements, but also the life of the driver board is also very high, so that it can reflect the overall performance of the product. reliability. Therefore, it is also necessary to estimate and predict the life of the driver board circuit inside the lamp product, especially the surge current during the switch startup process has a particularly serious impact on the life of the driver board. [0003] At presen...
