OVM4R-001

LEDs, or Light Emitting Diodes, are often found in the home for varying reasons, from general lighting to emergency lighting to the increasingly popular backlighting for flat panel TVs. Though most of us may be aware of their presence, we often do not consider their application fields and working principles in general. The OVM4R-001, a particular product in the LED indication – discrete series, provides a visual indication when an output relay is activated, and is used in the consumer and industrial markets. This article will outline the application fields and working principles of the OVM4R-001 LED product.

Application Fields

The OVM4R-001 discrete LED indication is suitable for a wide variety of consumer and industrial applications ranging from telecom to networking to consumer electronics to medical instruments and more. Its use can best be seen in medical machinery and consumer electronics, where it is frequently used as a warning of a problem that needs immediate attention. It is also used to show a product is in use and available to be interacted with. For example, in the soundbar on a television, it is used to show whether the volume is low (green) or high (red). The uses for the OVM4R-001 discrete LED product are only limited by the user’s imagination.

Working Principle

The OVM4R-001 works by emitting visible light when a current passes through a semiconductor junction. It is typically designed with two metal leads (an anode and a cathode) that can be connected to either a power source or a circuit. When the power source is connected, electrons are attracted to the positively charged anode and current flows through the diode and a light is emitted. The intensity of the light emitted is determined by the voltage of the power source and the internal resistance of the diode. The higher the voltage and the lower the internal resistance, the brighter the light.

Home electronics also benefit from the use of LEDs. For example, in a DVD player, an LED may be used to indicate when power is on. In this case, the LED will emit a small amount of light, regardless of the voltage. This is known as a low-voltage LED and is often used in consumer and industrial applications. As the voltage increases, the LED will become increasingly brighter, up to a certain point, known as the saturation point. After which, any increase in voltage will have no effect on the brightness of the LED.

LEDs are also used in more complex systems, such as switching and control. In these systems, an LED might be used to indicate when a button has been pressed or a relay is activated. A typical OVM4R-001 LED will be connected to a relay on one side and to a power source on the other. When the switch activates the relay, it closes a circuit and the LED is illuminated. This type of LED indication is extremely useful in a variety of applications, due to its simple yet effective design and operation.

Conclusion

The OVM4R-001 LED is a highly versatile product, with applications ranging from consumer electronics to medical instruments and more. While primarily used for discrete indication, it also has a variety of uses in other industries. Its relatively low cost, long life and low power consumption make it an ideal choice for a variety of projects, from low-voltage indicator lights to complex switching and control systems. Its operation is simple and reliable, and its applications are limited only by the user’s imagination.
