Embodiment Construction

[0012] The application will be further described below in conjunction with the accompanying drawings.

[0013] Such as Figure 1-2 As shown, the LED driving power supply circuit board includes: a transformer 4, a control circuit module 5, and a circuit substrate 1. The transformer 4 and the control circuit module 5 are electrically connected to the circuit substrate 1; Electrical contact pieces 3 are provided respectively.

[0014] The electrical contact piece 3 is a rectangular solder layer with a thickness of 0.2CM, on which a metal shrapnel 2 is fixed, the metal shrapnel 2 is in the shape of a human ear, and the material is preferably a steel sheet, and each of the rectangular solder layers has at least Fix a metal dome 2. During the test, the electrical contact piece 3 is directly clamped between the shrapnel of the tester, and the test can be performed. If there is no tester during the test, just use the traditional crocodile clip to clamp on the metal shrapnel 2, and ...

Abstract

The invention discloses an LED driving power supply circuit board with a test apparatus. The LED driving power supply circuit board with the test apparatus comprises the LED driving power supply circuit board. The circuit board comprises a transformer, a control circuit module and a circuit substrate, wherein the transformer and the control circuit module are electrically connected with the circuit substrate, the two surfaces of the two ends of the circuit substrate are each provided with an electrical contact sheet, the electrical contact sheets are rectangular soldering tin layers each having a thickness of 0.2 cm, metal springs are fixed on the rectangular soldering tin layers, and the circuit substrate is also provided with an indicating lamp. When a tester is connected with the electrical contact sheets, the indicating lamp can display whether the circuit board is at a normal state or a failure state. According to the invention, the two surfaces of the two ends of the circuit board are respectively provided with the electrical contact sheets, and such a structure can eliminate a welding process, directly test the circuit board and improve the production efficiency.

Description

technical field [0001] The present application relates to a circuit board, in particular to an LED driving power supply circuit board with a testing device. Background technique [0002] At present, LED lights have been vigorously developed due to their environmental protection and energy saving, and the long life of LED lights also plays a huge role in promoting them. In order to match with long-life LED lamps, the LED lamp drive power supply also needs to undergo an aging test to test whether the PCB circuit board of the drive power supply can maintain stability during long-term use. For this reason, every PCB circuit of the power supply must be strictly tested before leaving the factory. The usual test method in the prior art is to connect the test electrode to the PCB circuit by welding, then pass in a certain specification of current, and then put it in a test box at a certain temperature. The test time is generally 4 to 6 hours. The solutions in the prior art require...
