History of 5mm LED Packs

The history of LED technology dates back to the early 20th century when the first LED was invented. However, it wasn't until the late 1970s that LEDs began to gain popularity in the lighting industry. The development of 5mm LED packs can be traced back to the 1990s when manufacturers started producing high-quality, compact LED modules. These packs quickly became a favorite among lighting designers and engineers due to their versatility and efficiency.

Technology Behind 5mm LED Packs

5mm LED packs are composed of a semiconductor material, typically gallium nitride (GaN) or silicon carbide (SiC), which emits light when an electric current is applied. The size of these packs is determined by the diameter of the LED chip, which is 5mm in this case. The technology behind 5mm LED packs includes several key components: - LED Chip: The core of the 5mm LED pack is the LED chip, which emits light when an electric current is passed through it. The quality of the LED chip directly affects the brightness, color, and lifespan of the LED pack. - Lens: The lens is designed to focus the emitted light, ensuring optimal brightness and beam angle. Different types of lenses, such as diffused or clear, are available to meet various lighting requirements. - PCB (Printed Circuit Board): The PCB provides electrical connections between the LED chip and the power supply, as well as thermal management to dissipate heat generated during operation. - Heat Sink: A heat sink is often integrated into the 5mm LED pack to enhance thermal dissipation and prevent overheating, which can reduce the lifespan of the LED.
