Problems solved by technology

[0004] The present invention provides a LED driver board constant current testing tool and its testing method, which can realize the constant current of different driver boards by adjusting the adjustable contacts to the fixed contacts that need to load different numbers of LEDs when the driver board is tested. Performance testing solves the problems of inconvenient and low test efficiency caused by different driver boards requiring different numbers of test load LEDs and the need to remove the load LEDs inside the lamp during testing

Embodiment Construction

[0016] Embodiments of the present invention are described in detail below in conjunction with accompanying drawings:

[0017] Such as figure 1 As shown, the LED driver board constant current test tooling of the present invention includes: a current input terminal S, 13 LEDs are connected in series with the positive pole of the current input terminal S, and each LED is connected with a fixed contact G, which is connected to the positive pole of the current input terminal S. The guide rail D connected to the current input terminal S, and the adjustable contact K, one end of the adjustable contact K is slidably fixed on the guide rail D, and the other end is connected to the fixed contact G of any one of the LEDs, The positive and negative poles of the current input terminal S are connected to the positive and negative poles of the driving board.

[0018] Wherein, the number of the LEDs can be set according to different numbers of LEDs to meet the needs of different users.

Abstract

The invention provides a tool and a method for testing a constant current of an LED drive board. The tool for testing a constant current of an LED drive board comprises: a current input end, a plurality of LEDs connected with the current input end, a guideway connected with the current input end, and an adjustable contact. One end of the adjustable contact is slidingly fixed on the guideway, and the other end is connected to any one of the LEDs; and the positive and negative electrodes of the current input end are connected with those of the drive board. By adjusting the adjustable contact to fixed contacts the number of which differs when the number of load LEDs needed is different while a drive board test is conducted, constant current performance tests of different drive boards are realized, solving the problems of inconvenience and low test efficiency brought by the limitations that different drive board tests require a different number of load LEDs and that load LEDs inside a lamp need to be removed during a test.

Description

technical field [0001] The invention relates to a constant current test tool for LED drive boards and a test method thereof, in particular to a constant current test tool for LED drive boards compatible with various drive boards and a test method thereof. Background technique [0002] As a circuit driven by LED light source, the driver board is more and more widely used, and the short-circuit constant current performance test of the driver board is an important indicator to measure the life of the LED. [0003] The method used in the prior art to test the constant current performance of the driver board is to first remove the LED inside the lamp, and then connect the LED to the wire before testing, and the driver board needs to be tested during the test (the number of LEDs different) to adjust the wire to the corresponding LED contact point during the test. This test method often leads to poor contact of the LED, which seriously affects the quality, convenience and test effi...
