Technical Field
[0001] This application relates to the technical field of LED testing, and in particular to an LED strip testing device. Background Technology
[0002] In the production process of LED light strips, product quality inspection is a crucial step. Traditional inspection methods mainly rely on manual visual inspection. Although this method is simple and easy to implement, it has many limitations. With the advancement of technology, various automated inspection equipment has gradually emerged in the market. These devices not only improve the accuracy and efficiency of inspection, but also greatly reduce manual intervention. However, these advanced inspection devices often face problems such as high cost and complex operation, which limits their widespread application in small and medium-sized enterprises and individual users.
[0003] Currently, existing LED strip testing methods mainly rely on simple voltmeters or ammeters to measure the operating parameters of LED strips. Testers then visually inspect the brightness and uniformity of the LED strips after they are lit to judge their quality and whether they are qualified. However, existing LED strip testing methods generally depend on human experience and simple equipment, and the test results are greatly affected by subjective factors, making them prone to misjudgment. Even automated testing equipment is difficult to widely adopt due to its high cost and complex operation. Therefore, there is room for improvement. Utility Model Content

The heat dissipation vents on the rear cover effectively dissipate heat generated during circuit operation, guaranteeing long-term operational stability. The mounting screw holes and support plate securely fix the internal circuitry and power module, preventing damage from vibration or impact, thus improving the overall structural strength and service life of the device.
