LEDs have become popular in many applications because of their excellent energy efficiency and affordability. The H921HR7YD is a dimmable field LED (Field Emission Diode) developed by Shenzhen Hao Yue Technology Co., Ltd, widely used in various applications as circuit board indicators, light bars, bar graphs and LED arrays.

H921HR7YD Application Field

The H921HR7YD has a wide range of application fields. It is often used as a circuit board indicator for computer systems and gaming consoles. This LED is tall enough to be visible even in a narrow space. It provides clear, bright light, but it does not require much power consumption, so it can help to reduce energy consumption in comparison to other types of indicators.

The H921HR7YD is also used in LED arrays, such as message displays, warning lights, traffic signals and control panels. The array is configurable, and the user can change the number of LEDs and the dimensions of the array depending on the application. With its excellent brightness, the H921HR7YD is particularly suitable for outdoor applications, where visibility is essential.

The H921HR7YD is also popular in light bars, which are used in diverse applications like minor retail and commercial applications, automotive and train indicators, warning signaling lights, and many lighting applications. It is also used in bar graphs, which are basically an array of individual LED bars that can display numerical values. Its bright light makes it ideal for applications such as test and measurement systems, where the brightness of the LED bars needs to be readable.

H921HR7YD Working Principle

The H921HR7YD is a Field Emission Diode that relies on the principles of field emission technology to produce its dimmable light sources. The main components of this LED include the phosphor, electrode, and the field emission cathode. The field emission cathode generates the field of electricity, which causes the electrons to jump across the gap in the LED. As the electrons leave the LED, the phosphor material inside the LED begins to excite and produces visible light.

The H921HR7YD utilizes field emission technology to create dimmable, low profile options to all applications. Field emission technology is the process of creating electrical fields through the use of high voltages to manipulate the electrons within the LED. When the voltage is applied, the electrons jump up and down in strength, which allows the LED to dim. This is a precise, low power consuming process and leads to high efficiency when compared to other methods of dimming.

The H921HR7YD also features built-in resistance measurement, which helps to achieve precise dimming control and a long lifetime of usage. This is because the resistance measurement helps to detect the working temperature of the LED and then adjust the input power accordingly to help keep the LED working at the optimal temperature. As a result, the LED has a more consistent and reliable brightness over time and the operational life is extended significantly.

Conclusion

The H921HR7YD is a dimmable field LED that offers a range of great features and benefits. It is fast becoming popular for its excellent energy efficiency and affordability, as well as its wide range of applications. It has been used in diverse applications such as circuit board indicators, LED arrays, light bars and bar graphs, and it can be used both indoors and outdoors due to its bright and reliable light output. Its unique field emission technology makes it an efficient and flexible option, and the built-in resistance measurement helps to ensure an extended lifetime of operation. Overall, the H921HR7YD offers a great solution for many different applications.
