Based on color capabilities, they can be categorized into three types: single-color, multi-color (seven-color), and full-color (with individual pixel control). Single-color modules display only one color-commonly red, green, yellow, or white; multi-color LED modules can cycle through seven different colors; and full-color LED modules offer a richer range of true-color transitions.
Based on the power rating of individual LEDs, they are classified into three categories: low-power (under 0.3W), medium-power (0.3–0.5W), and high-power (1W and above). High-power modules generally offer higher brightness than low-power modules.
Based on sealing capabilities, they can be categorized into waterproof and non-waterproof types. Waterproof modules are primarily used for outdoor lighting and signage, featuring designs that prevent malfunctions caused by water ingress; non-waterproof modules are typically used in indoor environments. Waterproof modules generally command a higher price than non-waterproof ones.
Based on LED shape, modules are classified into: DIP (dual in-line package) LED modules, Piranha LED modules, and SMD (surface-mount device) LED modules. There are also specialized modules, such as those for irregular-shaped LED displays.
Based on packaging technology, they can be categorized into SMD and COB (chip-on-board) packaging. COB packaging offers superior heat dissipation and oxidation resistance, with no exposed component pins, making it suitable for harsh environments such as outdoor fine-pitch applications.
Based on electrical integration methods, they can be classified into integrated, semi-integrated, and non-integrated LED modules.
