5502207814F Application Field and Working Principle

LEDs – Circuit Board Indicators, Arrays, Light Bars, Bar Graphs

Light Emitting Diodes, or LEDs, are semiconductor devices which are used to indicate circuit operation. Actually, they are used everywhere in the world. A variety of packages and colors of LEDs are available on the market, ranging from single high flash (blue, green, red and white) through to multi-colored LEDs in strip, cluster and matrix formats. LEDs are useful wherever a status-indicating signal is required, such as in indicators, alarms, gauges, and digital displays.

5502207814F is a package and type of LED, especially designed for board-mounted indicator or display applications. It features an 18mm dual mounting-leg with a host of features including brightness boost and hi-decibel sound. It offers a wide variety of colors and RoHS compliance.

This type of LED is commonly used in a variety of applications such as consumer electronics, machine control, audiovisual and gaming equipment. In addition, it offers LED installation much easier than traditional LED modules.

Working Principle

LEDs are light sources which use electricity to generate light. When the electricity passes through the LED chip, electrons emit photons in the visible spectrum. This wavelength is determined by Radiance, a figure which measures the portion of light emitting. The higher the Radiance value, the higher the brightness of the LED.

5502207814F LED uses a direct connection circuit, which is connected between the cathode and current limiting resistor. This connection is called an anode, which is the positive or higher voltage side of the circuit. When an electrical current is received by the anode, the electrons are forced into the junction, creating an electrical field. When the electric field becomes strong enough, the chip\'s P and N layers emit light. This light is then emitted through the LED\'s dome, dispersing as visible light, instead of heat.

Conclusion

The 5502207814F LED is a popular LED solution in the LED industry around the globe. It is mainly used in applications involving LED indicators, displays, warning signals, and lighting. Its brightness, RoHS compliance and dual-mounting legs make it an ideal solution for a variety of applications. Moreover, its direct connection circuit ensures that the LED emits brighter and longer-lasting light.
