1. LED light-emitting diodes are generally divided into: in-line type, patch type, high-power, piranha in terms of model;

2. In-line LED lamp beads and light-emitting diodes commonly include straw hat lamps, round heads, flat heads, and the lamp body size is divided into: F3 F5 F8 F10;

3. The common SMD lamps are 0603.1206.0805.020.3528.2835.5050.5630.5730.2030, etc.;

4. High power refers to power above 0.5W, such as 1W 3W 5W 10W 20W.50W100W, etc., which are mostly used in lighting product applications.

5. Piranhas are divided into flat head type and bread type, which are mostly used for lighting and car lights.

6. LED lights are widely used in electronics, electrical appliances, communications, and lighting. Among them, the common household straw hat lights are in-line, SMD 3528.2835.5050.5630.5730. High-power common ones are 1-3-5-10W.
