LN250RPH is a component from the LED Indication-Discrete family. It is a high output, high efficiency, interior and exterior use indicator, designed for use in ATMs, copiers, medical and industrial equipment and human machine interfaces. This article outlines the application field and working principle of the LN250RPH.

LN250RPH is designed for the automotive, medical, industrial, security, and telecom equipment and human machine interface markets. This indicator is used in a variety of applications, such as lighting, status indication, power, and control. It is intended to be used in conjunction with other interface components, such as switches, potentiometers, or encoders, to provide visual feedback of the system\'s status. This can help operators quickly and easily identify the system\'s operational mode.

The LN250RPH has a wide input voltage range of 7-35V DC and is capable of delivering a total output of 250 lumens. It is rated at a 65° beam angle and has a maximum current rating of 550mA. It features a rugged construction and has a wide operating temperature range of -30 to +80°C, making it suitable for use in a variety of environmental conditions. Additionally, the LN250RPH is ROHS compliant and is rated for use in Class I, Division 2 hazardous locations.

The LN250RPH utilize a single or double contact switching configuration and has a wide variety of outputs such as colored LEDs and white backlighted sources. The built-in optics system ensures a uniform light emission with no hot spots and delivers a glare-free lighting solution. The LN250RPH also features a pre-focused beam pattern that helps reduce the need for additional optics, such as Fresnel lenses. In addition, the LN250RPH is designed with a durable, dust and moisture resistant housing that helps protect the device from the elements and extends its service life.

The working principle of the LN250RPH is simple - it utilizes an Auxiliary Voltage Converter (AVC) inside the device, which regulates the input voltage from 7V to 35V, depending on the application. The regulated voltage then powers the LED array, enabling it to emit a consistent and reliable light output. Furthermore, the LED array is driven by a constant current source, which ensures the LED light is always the same regardless of the input voltage. This ensures the LED light is always maintained at the same level, even when the input voltage changes.

The LN250RPH is also equipped with a unique feature called Power Bridging Technology (PBT). This enables the LN250RPH to maintain uniform light output, even when being turned on/off or having its power supply disconnected. PBT provides a quick and reliable recovery of system brightness. As a result, it can prolong the LED’s lifetime and operating temperature.

The LN250RPH is a versatile LED indicator perfect for a variety of applications, such as automotive, medical, industrial, security, and telecom. It is designed for use in harsh environments and is capable of delivering a high output, high efficiency lighting solution. Furthermore, it utilizes a wide variety of outputs and features a pre-focused beam pattern. Finally, the LN250RPH is designed with Power Bridging Technology, allowing for a reliable and efficient recovery of system brightness.
