LED indications are becoming more and more popular recently due to their combinations of high brightness, low power consumption, and long lifetime. Among these LED indicators, discrete LED indicators are especially common in applications like ATMs, UPSs, and home appliances, etc. The EAST20128GA1 is one of the many discrete LED indicators currently on the market and is a great choice for the above applications due to its advantages, such as long life, low power consumption, good contrast, wide viewing angle, and good luminous stability. This article will discuss the application fields and working principles of the EAST20128GA1.

Application Fields

The EAST20128GA1 is an LED discrete indicator that is commonly used in various applications. For example, it can be used in ATMs, UPSs, and home appliances. In ATMs, the EAST20128GA1 can be used to indicate the status, such as the "card inserted" and "payment processing" status. In UPS, it can be used for overload, short circuit, and other alarms, and in home appliances, it can be used for power, temperature, or other status indication. Additionally, it can also be used for signage and displays, such as for traffic signs, vehicle identification signs and control buttons.

Working Principle

The EAST20128GA1 is a discrete LED indicator composed of two components, a diode and a resistor. When the diode is forward-biased, it will allow electric current to pass through it and the resistor will reduce the current. The resistor can be adjusted to control the current level and the brightness of the LED. The EAST20128GA1 also contains a high voltage isolation layer to protect the diode from high voltage and other external factors. Moreover, it also includes a photo-sensor, which is used to detect light intensity and adjust the brightness accordingly.

In conclusion, the EAST20128GA1 is a discrete LED indicator that is commonly used in many applications for various statuses. Its working principle involves a diode, a resistor, a high voltage isolation layer and a photo-sensor.
