Abstract

The invention discloses an LED (Light Emitting Diode) performance test box, a calibrating method and a performance test method. The test case comprises a box body, a motor and a light taking device, and also comprises a transmission mechanism and an optical fiber, wherein the box body is provided with an opening, and the transmission mechanism and the optical fiber pass through the opening; the light taking device is arranged inside the box body, and the motor is arranged outside the box body; one end of the transmission mechanism is connected with a shaft of the motor, and the other end the transmission mechanism is connected with the light taking device; the motor drives the light taking device to move in the box body through the transmission mechanism; and a first end of the optical fiber is connected with the light taking device, and a second end of the optical fiber is outside the box body. The LED performance test box is simple in structure, and easy and simple to operate, and can detect LED performance parameters on line.

Description

technical field [0001] The invention relates to the field of LED testing, in particular to an LED performance testing box, a calibration method and a performance testing method. Background technique [0002] The currently prevailing LED reliability test method is: in the same model and batch of LED products, a certain number of samples are selected for testing, and their performance parameters are measured before and during the test, and calculated according to the corresponding lifetime algorithm. Model, LED life of the batch. Since the theoretical life of LEDs is tens of thousands of hours, it is necessary to use an intensive test method with enhanced stress to speed up the entire test process. [0003] In order to improve efficiency and optimize test results, it is common practice to conduct reliability tests on multiple LED samples at the same time. In the existing LED reliability test system, a tray is usually sampled, multiple LED samples are fixed on the tray, and t...
