LEDs, or light-emitting diodes, are used in a variety of applications ranging from traditional lighting products to emerging applications in display and automotive industries. One application of LEDs is in circuit board indicators, arrays, light bars, and bar graphs. The COM-09938 is an example of this application. It is worth learning about the features and working principles of the COM-09938.

Features

The COM-09938 is a versatile 8 segment LED array for board level illumination and display. It is designed to operate with a variety of logic families and offers a wide range of light output brightness. By combining logic level inputs and common anode outputs, the COM-09938 can act as a stand-alone indicator, or serve as part of an integrated solution. It is RoHS compliant and is UL approved. The COM-09938 is equipped with a grounding pin at the end of the device that prevents arcing and ensures a clean, safe operation. Additionally, the COM-09938 is designed to emit red, green and blue LED light.

Working Principle

The COM-09938 operates using current limiting resistors and logic inputs. By using logic level inputs, the current limiting resistors are eliminated, thus simplifying the circuitry of the design. The COM-09938 is designed to be used as an indicator, array or light bar. When used as an indicator, the device uses the logic level inputs to act as a steady-state indicator, meaning the device will remain activated until a logic level low is applied. When used as an array or light bar, the COM-09938 uses a PWM (pulse width modulation) signal to control the brightness of the indicator. The PWM signal controls the current flow to the LED array, allowing the user to adjust the light output to achieve the desired brightness or color.

Conclusion

The COM-09938 is a versatile 8 segment LED array designed for a variety of applications. It is RoHS compliant and UL approved, providing a safe and reliable solution. The COM-09938 operates using logic level inputs, eliminating the need for current limiting resistors and simplifying the circuitry. The device is designed to operate as an indicator, array or light bar, with the ability to adjust the light output using a PWM signal. The COM-09938 is a reliable choice for board level illumination and display.
