The CMW01H LED is a type of LED (Light Emitting Diode) that is ideal for application in a variety of circuits. This LED has a very unique design, with a yellow or green dome shape and a 1 cm long, 0.23 mm thick stem. This LED is often used in circuits where its brightness and color differentiation are needed. Its versatility makes it suitable for both frequent use and occasional use.

Application Field and Working Principle

The CMW01H LED is mostly used in the fields of LED arrays, bars, bar graphs, status indicators, and light bars. With its yellow or green color, it is best used for lighting applications that need to be highly visible. For example, in a status indicator application, this LED will be clearly visible from a distance and will let people know if a machine or equipment is in the “on” position or “off” position.

As for its working principle, the CMW01H LED has a built-in phototransistor, which works with two or three wires connected to the circuit board. This phototransistor performs various functions such as adjusting the light intensity, controlling the power supply to the LEDs, and monitoring the temperature of the circuit. This kind of LED also has a low thermal resistance, which ensures it stays cool during operation and prolongs its life.

The main advantage of the CMW01H LED is its compatibility with many types of circuit boards, ranging from small buttons to larger scale boards. This makes it an excellent choice for many types of applications, including arrays, status indicators, light bars, etc. Furthermore, this LED offers reliable performance under extreme temperatures, making it an ideal choice for rugged applications.

When it comes to operating this LED, it requires a DC voltage from 6V to 30V, making it suitable for both low and high voltage circuits. Additionally, its current draw is quite low, with a typical range of 2.4mA to 9mA, allowing for longer run times and reduced power consumption. Furthermore, this LED has a long life span, with an estimated range of up to 50,000 hours.

To conclude, the CMW01H LED is one of the most versatile LED types available, and it is suitable for a wide variety of applications. Thanks to its low thermal resistance, reliable operation, and long life span, it is ideal for illumination, safety, and other indicators. Its easy installation and compatibility with circuit boards make it a preferred choice for many projects and applications.
