Introduction to Cylindrical 10mm LED Industry

What is a Cylindrical 10mm LED?

The cylindrical 10mm LED, also known as a 10mm LED, is a type of light-emitting diode that is commonly used in various applications due to its compact size and versatility. These LEDs are characterized by their cylindrical shape, which measures 10mm in diameter and can be as thin as 2mm. The small size of these LEDs makes them ideal for embedding into a wide range of products, from consumer electronics to automotive lighting systems.

Cylindrical 10mm LEDs are typically made using a single crystal of gallium nitride (GaN) or a combination of GaN and indium gallium nitride (InGaN). The crystal is cut into a cylindrical shape and then processed to create the LED. The end of the cylinder is then coated with a phosphor, which converts the blue light emitted by the LED into white light, or a different color depending on the application.
