LEDs – Circuit Board Indicators, Arrays, Light Bars, Bar Graphs – have long been used as signaling devices in a variety of applications. The H2921R7YD is a particularly versatile LED that is typically used in industrial settings and human-machine interfaces. This article will discuss the features, application field, and working principles of H2921R7YD LEDs.

Features

The H2921R7YD is a highly efficient LED, achieving a brightness of up to 700 millicandela (mcd). It boasts an operating life of up to 100,000 hours, and it’s capable of withstanding extreme temperature fluctuations. Most importantly, the H2921R7YD is unidirectional, meaning it emits light in a specific direction, which makes it extremely useful in settings where directional visibility is a concern.

Application Field

H2921R7YD LEDs are primarily used in settings where a single LED is needed for signalling or indicating in a specific direction. This makes the device especially useful in industrial settings, where directional visibility is often important. In addition, the H2921R7YD is also used in human-machine interfaces and automotive control systems. As a result, the H2921R7YD is a highly versatile LED with a wide range of applications.

Working Principle

The H2921R7YD consists of a semiconductor diode encapsulated in a housing. When electricity passes through the diode, electrons jump from their valences to conduction bands. This process generates light in the form of photons, which is then emitted from the LED. The specific color of light emitted from the LED depends on the type and quantity of impurities present in the semiconductor. The overall brightness of the LED is affected by increased or decreased voltage. Depending on the electrical characteristics of the LED, the brightness can be adjusted.

Conclusion

The H2921R7YD is a highly effective and versatile LED with a wide range of applications in industries, including industrial settings and human-machine interfaces. Its unidirectional light emission makes it especially useful in directional visibility settings. The H2921R7YD’s robust design also ensures a long life and good performance in extreme temperature fluctuation conditions. All of these attributes make the H2921R7YD a suitable choice for applications in a wide variety of settings.
