Through light source intensity detection, the brightness consistency between the modules and the brightness uniformity of the lamp beads inside the module can be ensured, and the phenomenon of uneven brightness is avoided, so that the display effect of the whole LED display screen is improved. The light source intensity not only affects the brightness, but also is closely related to the color performance. Detecting the light source intensity helps to adjust the color balance of the LED display module, ensures the accurate color restoration, and makes the color performance of the whole display screen more consistent and real.

[0003] At present, in the conventional operation of detecting the light source intensity of the LED display screen, a luxmeter, a professional tool, is usually used to carry out the detection work. However, the LED display screen is not a single light source, but is composed of a plurality of LED display modules. These display modules are often arranged at different height positions according to the installation requirements and design effects in actual application. When the luxmeter is used to detect the light source intensity of the LED display modules at different heights, the detector will face many inconveniences:

[0004] Due to the different heights of the display modules, the detector needs to frequently adjust the position and angle of the luxmeter to ensure that the light source intensity of each module can be accurately measured. For some LED display modules installed at high positions, the detector often needs to use a ladder and other auxiliary tools to approach and detect, which increases the difficulty of the detection work and leads to low detection efficiency.

[0005] Therefore, an LED display screen light source intensity detection device is provided. UTILITY MODEL CONTENTS
