1. The in-line LED adopts the form of two-pin in-line. Because of the large thermal resistance of the package and the poor heat dissipation of the chip, the light effect decays quickly and the lifespan is relatively short. It is cheap and can be made into a small angle.
2. SMD LEDs can adopt 2-pin, 4-pin, and 6-pin patch methods. They are commonly used light sources at present. The larger the package shape, the better the heat dissipation performance, and the larger the withstand power. The greater the output light energy.
3. Piranha is a 4-pin in-line package with better heat dissipation and reliability than ordinary 2-pin in-line package.
4. High-power LEDs, which are designed with large-size chips and enhanced hot channel technology, are commonly used in multiple specifications such as 0.5W, 1W, 3W, and 5W. A single lamp bead can withstand a working current of more than 300mA. And output more than 100 lumens of luminous flux, widely used in commercial lighting.
