LED in LED light tweezers is the abbreviation of English light emitting diode, which is what we call "light emitting diode"; the classification of LED can be divided into many types according to the type of LED or other various conditions:

1. According to the power size: it can be divided into low power and high power (in the industry, lights above 1W are generally called high-power lights, and 1W is commonly used);

High-power refers to products with high luminous intensity, such as common LED lamps, because these products have relatively large chip sizes and high luminous efficiency (higher brightness), so they are classified as high-power LEDs and are commonly packaged. For Piranha, Emitter, SMD, Lamp, etc.;

Low power refers to products with low luminous intensity, such as common indicator lights, mobile phone backlights, etc., because the chip size of such products is relatively small and the luminous efficiency is low (low brightness, usually used for indication and display), Therefore, it is classified as high-power LED, and the common packaging methods are piranha, SMT, Lamp, etc.;

2. According to the packaging method, there are two types: plug-in type and patch type:

The plug-in type means that when the component is used, holes (drilling holes) are required on the PCB base, and the components need to pass through the PCB board to be soldered; such components usually have long external pins, such as the common Lamp, Piranha, etc.;

The SMD type means that when the component is used, there is no need to open holes (drill holes) on the PCB base, and the components can be directly attached to the PCB board for welding; such components usually do not have external pins (or chips). metal electrodes), such as common SMT, Emitter, etc.;
