What do I need to pay attention to when choosing a plug-in diode?

Plug-in diodes, led lights light-emitting diodes selection to pay attention to the following characteristics:

1, color, 2, package size, 3, forward voltage, 4, power consumption, 5, cost, 6, operating temperature.

2, led light-emitting diode characteristics:

Light-emitting diode fundamental structure light-emitting diode is referred to as LED, the main materials that make up the LED include: tube core, adhesive, gold wire, bracket and epoxy resin. 

Light-emitting diodes are divided into SMD and plug-in according to the assembly method. 

According to the type of light-emitting can also be divided into general monochrome light-emitting diodes, high-brightness light-emitting diodes, color-changing light-emitting diodes, flashing light-emitting diodes, voltage-controlled light-emitting diodes, infrared light-emitting diodes.  

1, general monochrome light-emitting diodes: 

General monochrome light-emitting diodes have the advantages of low volume filial operating voltage, operating current filial luminous uniformity and stability, fast response time, long life, etc., available in a variety of DC, AC, pulse and other power supply drive light. It belongs to the current manipulation type semiconductor equipment, the use of the series need to connect the appropriate current limiting resistor. 

General monochrome light-emitting diode light-emitting color and wavelength of light, and the wavelength of light depends on the production of light-emitting diodes used in semiconductor materials. Red light-emitting diode wavelength is generally 650 ~ 700nm, amber light-emitting diode wavelength is generally 630 ~ 650nm, orange light-emitting diode wavelength is generally 610 ~ 630nm, yellow light-emitting diode wavelength is generally about 585nm, green light-emitting diode wavelength is generally 555 ~ 570nm. 

Commonly used domestic general monochrome light-emitting diodes have BT (factory standard type) series, FG (Ministry standard type) series and 2EF series. Commonly used imported general monochrome light-emitting diodes have SLR series and SLC series, etc.

2, high brightness light-emitting diodes: 

High-brightness monochromatic light-emitting diodes and ultra-high-brightness monochromatic light-emitting diodes use different semiconductor materials and general monochromatic light-emitting diodes, so the intensity of light is also different. In general, high-brightness monochromatic light-emitting diodes using gallium arsenide (GaAlAs) and other materials, ultra-high brightness monochromatic light-emitting diodes using gallium indium arsenide phosphorus (GaAsInP) and other materials, and general monochromatic light-emitting diodes using gallium phosphide (GaP) or gallium arsenide phosphorus (GaAsP) and other materials.  

3, color-changing light-emitting diodes: 

Color-changing light-emitting diodes are able to change the color of light-emitting diodes. Color-changing light-emitting diode light-emitting color varieties can be divided into two-color light-emitting diode, three-color light-emitting diode and multi-color (with red, blue, green, white four colors) light-emitting diode. 

Color-changing light-emitting diodes according to the number of pins can be divided into two-terminal color-changing light-emitting diodes, three-terminal color-changing light-emitting diodes, four-terminal color-changing light-emitting diodes and six-terminal color-changing light-emitting diodes. Commonly used two-color light-emitting diodes have 2EF series and TB series, commonly used three-color light-emitting diodes have 2EF302, 2EF312, 2EF322 and other types.

4, voltage-manipulated light-emitting diodes: 

General light-emitting diodes belong to the current manipulation type equipment, in the use of the series need to connect the appropriate resistance value of the current limiting resistor. Voltage manipulated light-emitting diode (BTV) is a light-emitting diode and current-limiting resistor integrated production as a whole, the use of direct parallel connection in the power supply at both ends. 

5, infrared light-emitting diodes: 

Infrared light-emitting diode, also known as infrared emitting diode, it is able to convert electrical energy directly into infrared light (invisible light) and can be radiated out of the light-emitting equipment, mainly used in a variety of light control and remote control transmitter circuit. 

Infrared light-emitting diode structure, principles and general light-emitting diode near, but the use of semiconductor materials are different. Infrared light-emitting diodes generally use gallium arsenide (GaAs), gallium arsenide (GaAlAs) and other materials, using fully transparent or light blue, black resin package. 

Commonly used infrared light-emitting diodes are SIR series, SIM series, PLT series, GL series, HIR series and HG series, etc.
