LED Indication - Discrete: SM1204SRC Application Field and Working Principle

LED (Light Emitting Diode) technology has a wide range of applications in modern life, from industrial and commercial use to decorative lighting. As part of this, the SM1204SRC is a discrete LED module from Everlight Electronics that is primarily used for industrial, automotive and medical equipment, as well as panel meters. This article will provide an overview of the application field and how the SM1204SRC works, to give a better understanding of the benefits it can offer.

Application Field

The SM1204SRC is an LED module primarily used in industrial, automotive and medical equipment. By utilizing it in automated equipment, manufacturers can increase product performance and expand service capabilities. It has a wide range of applications in the industrial field, primarily as a signal indicator in these machines. In automotive applications, it is often used in dashboard indicator lights, and in medical equipment, it is often found as an indicator for certain tests. The SM 1204SRC also has applications in panel meters, where it serves as an indicator for voltage or current.

Working Principle

The SM1204SRC is a 3-digit module that features a 7-segment display, allowing for easy readability. It operates through a 7-bit data code that determines what color and pattern the module displays. The 7-bit code can be programmed to light up in different patterns and colors such as red, blue, green and yellow. Through this, the module can be used to indicate different objects’ relative states in a simplified manner.The SM1204SRC works through a combination of two ICs. The first IC is the LED control IC which is responsible for interpreting the input data code and controlling how it is displayed. The second IC is the LED segment driver IC which controls the number or pattern of LEDs that will be turned on or off at any given time. The two ICs are connected by a 7-bit data line, allowing for a wide variety of different patterns. The SM1204SRC is a DC-operated module and requires a current of not more than 25mA to operate properly. It has a low VF value of 2.3V, making it an efficient and reliable source of lighting.

Conclusion

The SM1204SRC is a discrete LED module from Everlight Electronics that is primarily used for industrial, automotive and medical equipment, as well as panel meters. It operates through a combination of two connected ICs, and requires a current of less than 25mA. It can be programmed to display different patterns and colors through a 7-bit data code, and has a low VF value of 2.3V. With the many applications of the SM 1204SRC, it is clear that it is a reliable, efficient and versatile module that can fulfill a wide range of needs.
