2191L5-6V Application Field and Working Principle

Panel Indicators, Pilot Lights

The 2191L5-6V pilot light is an LED indicator light for an instrument panel or a control panel. It features a high visibility, bright green LED, large cap housing, and a bezeled housing for added protection against shock and vibration. The panel indicator can be used in applications that require a stand-alone lighting element to alert a user or to serve as part of an enclosure control system. Its application fields include process control systems, automation equipment, and instrumentation.

The 2191L5-6V is easy to install. It comes with mounting hardware, flexible mounting plates, and gasket washers to help secure the unit in the panel or enclosure. The LED is rated for up to 10,000 hours of continuous operation, and its color temperature is 5,500K.

The 2191L5-6V pilot light operates based on the concept of electroluminescence, which is the process of converting electrical energy into visible light. When the LED receives electrical power, electrons in the LED are excited to higher energy levels by a voltage applied across the diode. As the electrons recombine, they emit photons of light. The amount of energy released is determined by the frequency of the applied voltage and the color of the resulting light is determined by the strength of the electric field.

The 2191L5-6V light is very reliable and can operate even in harsh environments. It is waterproof and dustproof, and its LED light is highly visible in all environments. It is also highly resistant to shock and vibration and is UL1061 rated.

The 2191L5-6V is an efficient and reliable way to provide visual indication in a variety of applications. It is an energy-saving lighting system with an exceptionally long life. Its bright, visible LED and easy installation make it an excellent choice for any instrument or control panel.
