LED modules are widely used in LED products. There are also great differences in structure and electronics. The simple thing is to use a circuit board and shell with LEDs to become an LED module. On some controls, constant current source and related heat dissipation treatment make LED life and luminous intensity better.
2. How to solve the "mosaic" problem of LED display? Use the same batch of red, green and blue LED lights on the LED display manufacturer, and re-classify the red, green and blue of this batch of LED lights . The constant current device is divided into 5 grades, and the constant current source of each grade is evenly distributed to the whole screen for LED unit board production. Standard production fixtures are used to ensure that the LED lights are in the same module. the same equilibrium position.
Control the mold making process to ensure that all LED lights in the module are not abnormally offset horizontally, up and down, and front and back. After the glue is poured, use the standard front cover to fix the light. Each LED unit board performs single-module brightness adjustment, that is, white balance fine-tuning, to ensure uniform white balance between modules.
Assemble the modules into a box. The box body adopts the steel reinforced structure, and the reinforcement is added in the appropriate position. Ensure the rigidity and flatness of the box plane. The punching and bending of the box is formed by CNC equipment at one time, and the CNC punching machine is used to ensure the accuracy of the module installation. And there is an appropriate margin to eliminate accumulated errors.
