Abstract

The invention provides a device for testing on-off of a luminous body. The device comprises a direct-current power supply for providing working voltage of other equipment, a power switch relay for controlling on-off of a power supply of the luminous body, and a time relay circuit for controlling the on-off time of the power switch relay; wherein the direct-current power supply, the time relay circuit and the power switch relay are sequentially connected. The device provided by the invention has the advantages of simple structure, convenience in use and low cost; high maintenance cost of such devices every year is saved; single measurement volume is large, and the power of the power supply can be improved according to the power of a product to be tested, so that the single measurement volume of the product is improved; the single measurement volume is improved by more than 11 times; and the device provided by the invention has high test accuracy, short time delay, and fast detection speed.

Description

technical field [0001] The invention relates to the field of product quality testing, in particular to a device for performing multiple switch tests on luminous body products. Background technique [0002] LED, OLED, CCFL, fluorescent lamp and other illuminant light sources need to test the reliability test of On / Off (switch machine). The principle of the test: Connect the light source of the luminous body to the power supply to make it run normally. Then set a very short time (most of the current test standards are 30 seconds or 10 seconds switch) to pass the On / Off device, test it on and off, and then test it in a continuous cycle. Its purpose is to measure the reliability of the light source of the luminous body, and detect whether the problem of brightness decay and product failure occurs. At present, the price of this On / Off (switch machine) equipment is relatively expensive, and most of them are made in Japan. The original On / Off machine working mode has low test ac...
