LTL-4221NH117

LEDs have become the preferred method for providing a simple, reliable and cost-effective way to indicate visual signals on electrical or electronic circuits. LTL-4221NH117 is among the variety of LED lamps that can provide a bright visual indication in a variety of circuit applications. This article is going to focus on the application field and working principle of this lamp.

Application field

The LTL-4221NH117 is commonly used as an indicator light on the front panel of electronic equipment, especially under the area of industrial control. It is widely used in the dynamic current control of pumps, fans and other equipment. In recent years, LED technology has been used increasingly in applications such as instrumentation and control panels, machine tools, medical equipment and lighting fixtures. The LTL-4221NH117 has been designed to provide quality illumination to a wide range of applications, where bright and reliable illumination is required.

The LTL-4221NH117 is ideal for lighting up displays on circuit boards, replacing conventional indicators such as light bars, bar graphs and green LEDs. The lamp has a much longer life expectancy than conventional lamps, with a minimum illumination of 10,000 hours. It is also highly energy efficient and has an impressive lumen efficiency of more than 90%.

Working principle

The LTL-4221NH117 consists of a glass envelope containing an anode and a cathode. The anode and cathode are connected to a small glass cap. When electric current flows through the anode, it emits ultraviolet radiation, which then excites the phosphor coating inside the glass envelope. This excitation of the phosphor coating causes the lamp to produce white light. The lamp is capable of producing a consistent and reliable illumination over a long period of time.

The lamp has a special current-limiting feature, which helps to limit the amount of current passing through the anode. This helps to reduce energy consumption and prolong the life of the lamp. The lamp also has a voltage-regulated feature, which allows an adjustable output voltage. This makes the lamp ideal for a variety of applications and makes it possible to customize the brightness of the lamp.

Conclusion

The LTL-4221NH117 is an ideal LED lamp for use in a variety of applications, from industrial control to lighting on circuit boards. It offers a long life expectancy and high lumen efficiency, making it a great choice for those looking for a reliable, energy efficient LED lamp. In addition, the lamp has special current-limiting and voltage-regulated features that make it easy to customize the brightness of the lamp for a variety of applications.
