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

The H178CBC-3 is a type of light-emitting diode (LED) circuit board indicator. LED\'s have become increasingly popular for their efficiency, small size and low energy consumption. They are used for light displays such as illuminated signs, traffic signals, and outdoor lighting.

The H178CBC-3 is designed for use with a wide variety of applications. It is constructed with an epoxy resin body and a heat sink at the rear. It has an integrated circuit board with a built-in constant current of 3A, which ensures consistent and accurate illuminance. It also has an additional 1A output current that can be used to power other components of the circuit board.

The H178CBC-3 is ideal for applications that require high illuminance levels with minimal electromagnetic interferenceand low electrical consumption. It is often used to power arrays of LEDs, light bars, and bar graphs that are needed to display data and information.

Working principle

The H178CBC-3 works on the principle of using a current to flow through a junction of a semiconductor material, such as gallium arsenide, to cause light emission. This junction is known as a p-n junction and is created by adding impurities to the material to create either a positive or negative charge. This current is often supplied by a driver circuit, which controls the amount of current that flows through the p-n junction.

The amount of light emitted from the p-n junction depends on the amount of current that is applied. The higher the current, the more light is emitted. The current is also modulated to control the brightness of the LED. This allows for a wide range of applications, such as lighting a certain area or creating a flashing effect.

Conclusion

The H178CBC-3 is a type of LED circuit board indicator that is ideal for applications that require a high level of illuminance with minimal electromagnetic interference. It is constructed with an epoxy resin body and a heat sink at the rear and has an integrated circuit board with built-in constant current of 3A. This LED is often used to power arrays of LEDs, light bars, and bar graphs that are used to display data and information in illuminated signs, traffic signals, and outdoor lighting.
