LED Indication - Discrete: R20BLU-5-0080 Application Field and Working Principle

LED Indication - Discrete is a type of technology used to indicate a signal through a blinking light. It is an indication technology based on light emitting diodes (LEDs) that blinks in high frequency through pulsed current. LEDs or light emitting diodes are semiconductor diodes that emits light when a voltage is applied across the forward direction of the p-n junction. The R20BLU-5-0080 model is one such popular example of discrete LED indication technology.

Overview of R20BLU-5-0080

The R20BLU-5-0080 is a discrete LED indicator used for two-color, two-state status display in audio and communication equipment, consumer electronic products, switches and indicators, and medical and automotive products. This model is compliant to RoHS, UL, cUL, CE, and CQC standards. The feature set includes an ultra-bright, multi-colored light emission of blue and green, with a wide viewing angle of 120 degrees. The light emission intensity is 85mcd typical (μA = 20mA).

Application Field of R20BLU-5-0080

The R20BLU-5-0080 is ideal for any application related to audio, communication, consumer electronics, switches, indicators, medical and automotive products. It provides a bright, attractive light and can be used for visual status indication such as “on/off”, “open/close”, or “yes/no”. It is also often used in alarm systems, digital alarm clocks, toys, and computer peripherals.

Working Principle of R20BLU-5-0080

The R20BLU-5-0080 is activated by applying a voltage across the forward direction of its p-n junction. This causes electrons to move from the electrode connected to the p-type semiconductor to the electrode connected to the n-type semiconductor, producing an electric current and light energy. The emitted light has a wavelength of around 486.5nm blue and 568.6 nm green. The intensity of light emission can be adjusted by changing the current value.

Pros & Cons of R20BLU-5-0080

The R20BLU-5-0080 delivers a bright and attractive light output, with a wide viewing angle of 120 degrees. It is in compliance with various standards (RoHS, UL, cUL, CE, and CQC) making it a safe and environmentally friendly option for connecting electronic products. Also, its low power consumption helps to reduce energy wastage. On the other hand, the device is not suitable for dimming and it may require additional circuitry for more complicated light patterns.

Conclusion

LED Indication - Discrete technology is an important element for many communication and electronic devices. The R20BLU-5-0080 is a great example of discrete LED indication technology and this model can be used in various applications related to audio and communication products, consumer electronics, switches, indicators, and medical and automotive products. When used in combination with suitable circuitry, this device can help to reduce energy consumption and provide a bright, attractive light display.
