LED indication has been used in a wide spectrum of applications due to its bright and visually appealing features. Discrete LED indication typically provides a single point of indication, i.e. providing an indication status at a single point on the device or product. In this article, we will be discussing the application field and working principles of one of the most common discrete LED indicator - the CP41B-GFS-CM0Q0674.

Application Field

The CP41B-GFS-CM0Q0674 discrete LED indicator is most commonly employed in the automotive industry and in consumer electronics. In the automotive sector, it is usually used to indicate the operational status of onboard systems such as fuel level, oil pressure, alternator charging, and other similar functions. In consumer electronics, it is used to indicate the operational status of devices such as DVD and Blu-Ray players, CD players, microwaves, dishwashers, toasters, and a wide range of other electronic appliances.

Physical Design

This discrete LED indicator is housed in a hemispherical shell of 30 mm diameter and 4 mm depth. A 12 mm diameter polarized lens of type "F" design is fitted on top of the indicator for added visual appeal. The indicator is finished in black and is resistant corrosion and harsh environmental conditions. A 5.6 mm diameter male terminal is present at the rear of the indicator for connection to the power supply.

Mechanical Design

The interior of the indicator is made up of an LED, a resistor, and a miniature accompanying switch. The LED used is of type CP41 LED, with a peak voltage rating of 3V, a forward current of 50 mA and a wavelength of 590 nm. The resistor is a 10K ohm resistor with a power rating of 0.25W. The accompanying switch is a single pole toggle switch, with a rated power of 1W.

Working Principle

The working principles of the discrete LED indicator are quite simple and straightforward. When the switch is activated, the LED is illuminated, signalling that the device is functioning. If the LED does not illuminate, this is an indication that the device is not functioning correctly. The resistor is necessary for limiting the current that flows through the LED to ensure that the voltage does not exceed the LED\'s rated voltage.

Conclusion

The CP41B-GFS-CM0Q0674 discrete LED indicator is a reliable and cost-effective solution for providing single point indication in a wide range of applications. Its simple design and easy installation makes it a popular choice among automotive and consumer electronics manufacturers. Additionally, its rugged mechanical design and corrosion-resistant finish ensure that it will provide reliable operation even in harsh environmental conditions.
