EALP05RDDYA0

Introduction

EALP05RDDYA0 is a type of LED Indication - Discrete, which stands for enhanced amber light pattern 0.5” double digit. It is composed of two 0.5-inch (2.0mm) four-digit numeric or alphanumeric displays, each one with a six-segment common cathode alphanumeric display. It allows the user to monitor and control their operation using an LED display. The light emitting elements are categorized into discrete, parallel driving, serial driven, and multiplexed.

Application Fields

The application fields of EALP05RDDYA0 LED indication - Discrete is to indicate the status of electronic equipment or to indicate the alarm, warning and working parameters. It is ideal for use in product development and consumer applications, such as consumer computers, home security system, industrial control systems and automobile industry etc. It is also used in street warning lights and traffic signals, railroad signaling, and airport signaling applications.

Working Principle

The working principle of this LED indication - Discrete is based on the combination of two 0.5-inch four-digit numeric or alphanumeric displays. It works by applying a voltage to the anode of each segment of the display. When the voltage is applied to the anode of the display, it activates an LED and the segment is illuminated. The intensity of the light emanating from the segment depends on the voltage, current and other factors. Generally, the intensity is proportional to the applied voltage and current.

The multiplexed driving of this LED is based on the time-division principle. In this method, the LEDs are scanned at a particular frequency and each segment is illuminated in a sequential manner. This reduces the current consumption as the number of active segments at any given time is reduced. The LEDs are scanned in such a way that each segment is illuminated for a brief duration of time.

Conclusion

To sum up, EALP05RDDYA0 is a type of LED indication - Discrete which is used for many applications such as in street warning lights and traffic signals, railroad signaling, and airport signaling. It works by applying a voltage to the anode of each segment of the display to activate an LED and create an illuminated segment. The intensity of the segment is proportional to the applied voltage and current. It is based on the combination of two 0.5-inch four-digit numeric or alphanumeric displays and employs the time-division principle to reduce the current consumption.
