What is the lamp bar, what is led module, and what is the power supply? Today, we will understand the definition and classification of LED modules. The definition of LED module LED modules is widely used in LED products, and there are also great differences in structure and electronics. The easiest thing is to use a circuit board and shell to become a LED module with LED. Complex things are to increase some control, constant current sources and related heat dissipation treatment to improve the life of LED and light emitting intensity. LED module classification 1. From luminous color, it can be divided into: monochrome modules, two -color modules and full -color modules; 2. From the use of space, it can be divided into indoor modules, semi -outdoor modules and outdoor modules; 3. According to the power of LED lamp beads: small power (less than 0.3W), medium power (0.3-0.5W), high power (1W and above); 4. Sub -packaging: Online LED display module, indoor lattice LED display module, surface installation LED display module; 5. Pixel spacing: indoor P2.5, P3, P4, P5, P6, P7, P8, etc.; Outdoor P10, P12, P16, P20, P25, etc.
