Description

Technical Field

[0001] The utility model relates to the technical field of LED testing devices, in particular to a multi-channel LED testing device. Background Art

[0002] LED testing device is a device used to test the performance of LEDs, mainly testing the color and brightness of LEDs. This device can be implemented by a dedicated analyzer or manual visual inspection. The advantage of a dedicated analyzer is that it can quickly and automatically test the color and brightness of LEDs, and can accurately reflect the color performance of LEDs in different color spaces.

[0003] When testing LEDs, analyzers are mostly used for detection.

Therefore, we propose a multi-channel LED testing device to solve the above problems. Utility Model Content
