LEDs (Light Emitting Diodes) are one of the most widely used components in the world of electronics - from small household devices to complex industrial automation. They are increasingly being used in a variety of applications, from individual signs and decorative displays to applications involving circuit board indicators, arrays, light bars, bar graphs and more. The XEMR21D is one such LED series, developed by Nortek Electronics and designed for high output, long life and low power consumption. Here, we will take a look at the XEMR21D’s application field and working principle.

Application Field

The XEMR21D has a wide range of applications, including:

• Indicators
• Light bulbs
• Light bars
• Backlight modules
• Decorative displays
• Automobile lights
• Medical lighting
• Bar graphs
• Control buttons

These applications are supported by a range of features, including:

• High output – up to 1000+ millicandela at 20mA
• Long life – up to 100,000 hours
• Vibration resistance – up to 10G
• Low power consumption
• High brightness
• High tolerance to moisture, dirt, and UV light
• Wide variety of shapes and sizes
• Wide range of color options

Working Principle

The XEMR21D is a surface mount LED series that is designed to be used in a variety of applications. It works by using a combination of positive and negative voltages to move an electron from one layer of material to another, producing light. The light is then focused to a specific direction by the shape of the die and the surface mount lens.

The XEMR21D consists of two main components:

• Light Source – This is the Light Emitting Diode (LED), which is composed of a chemically treated semiconductor material that when triggered with a voltage, produces light of a specific wavelength. Depending on the type of LED, this can be a range from visible light to infrared light.
• Lens – This is an optical surface that covers the LED, allowing the light to be focused into a defined shape and direction. This is important for achieving the desired effect in a specific application.

The XEMR21D is designed to provide high efficiency and low power consumption in applications where high illumination is required. Its advantages include low maintenance costs, long life expectancy, and the ability to operate in extreme temperatures, vibrations, or humid environments. It is safe to use, as it does not produce high temperatures or require high voltages in order to operate.

The XEMR21D is a versatile LED series with a wide range of applications. It is well-suited for a variety of uses, from indicators and decorative displays, to control buttons and bar graphs. Its high-efficiency and low power consumption make it a reliable and cost-effective choice for any project.
