Abstract

The invention belongs to the technical field of aging test equipment and relates to an LED backlight strip aging test device. The LED backlight strip aging test device comprises a box body; a test cavity with an opening in one side is formed in the box body; four supporting columns are fixedly installed at the bottom of the box body; a box door is rotationally installed at one side of the box body; a first installation hole is formed in the inner wall of the bottom of the test cavity; a first rotary shaft is rotationally installed in the first installation hole; and two ends of the first rotary shaft extend out of the first installation hole. The LED backlight strip aging test device has the advantages of high practicability and convenience in operation. With the LED backlight strip agingtest device of the invention adopted, the adjustment of the horizontal positions of second U-shaped clamping plates can be facilitated, and therefore, the six second U-shaped clamping plates are matched with six first U-shaped clamping plates, so that six backlight strips can be clamped and fixed; the most of the surfaces of the backlight strips are in suspended states; the backlight strips can berotated slowly, so that the backlight strips are uniformly heated; and therefore, the accuracy of testing results is improved, and working efficiency is improved.

Description

technical field [0001] The invention relates to the technical field of aging testing equipment, in particular to an aging testing device for LED backlight strips. Background technique [0002] Nowadays, with the development of science and technology and the progress of society, LED lights have gradually replaced the lighting work of incandescent lamps. LED lights have the advantages of long service life, energy saving and environmental protection, high brightness, wide luminous area, low calorific value, safety and reliability, etc. LED lights The use of lamps is becoming more and more widespread. Before mass production of LED backlight strips, it is necessary to use aging test equipment to conduct aging test experiments on LED backlight strips to test the requirements for reliable service life of LED backlight strips. [0003] However, in the prior art, the commonly used LED backlight strip aging test equipment heats the backlight strip unevenly, resulting in uneven heating...
