Description

Technical Field

[0001] This utility model relates to the field of light-emitting diode (LED) testing, and in particular to a voltage limiting test device for testing the performance of LEDs. Background Technology

[0002] A search of Chinese patents revealed publication number CN213181642U, which discloses a voltage limiting test device for LED street light diodes. The device includes a testing instrument body. The front end of the instrument body is equipped with an instrument pointer, a display screen, and a knob. The front end also has a socket with an intermediate connection hole for inserting a diode. Handles are located on both sides of the front end of the instrument body, and a support device is located at the bottom, rotating around the interior of the instrument body. This invention, a voltage limiting test device for LED street light diodes, belongs to the field of diodes. By pressing the electrode leads in the testing hole with a pressure block, diode testing is made more convenient. After releasing the pressure, the electrode leads can be easily removed. By rotating a rotating bar around a rotating groove, a support plate can be placed on a flat surface, allowing the testing instrument body to be supported. This method is more convenient than using handles for support.

[0003] Existing voltage limiting test devices lack storage functionality. After use, the test pens and wiring are typically separated from the instrument for storage, which can easily damage them. Furthermore, they are inconvenient to carry and prone to loss, reducing their practicality. They also lack protective features; components such as the sockets, gauges, and displays on the surface of the voltage limiting test device are exposed to dust when not in use and are susceptible to damage from impacts, affecting their lifespan. To address these issues, we propose a voltage limiting test device for LED performance testing. Utility Model Content
