Technology Behind LED Diode 3W

The 3W LED diode operates based on the principle of electroluminescence. When an electric current passes through the diode, electrons recombine with electron holes, releasing energy in the form of light. The following key components contribute to the performance of a 3W LED diode: 1. LED chip: The LED chip is the core component of the diode, where the electroluminescence process occurs. It is typically made of a semiconductor material, such as gallium nitride (GaN), silicon carbide (SiC), or aluminum gallium indium phosphide (AlGaInP). 2. Heat sink: To dissipate heat generated during operation, a heat sink is attached to the LED chip. This helps maintain the optimal operating temperature and extends the lifespan of the diode. 3. Lens: The lens focuses the emitted light into a specific beam angle, which determines the light distribution pattern. Different lens types are available to meet various application requirements. 4. PCB (Printed Circuit Board): The PCB provides electrical connections between the LED chip, heat sink, and other components. It also serves as a mounting platform for the diode.
