Technology of RGB LED SMDs

RGB LED SMDs consist of three primary colors: red, green, and blue. Each color is represented by a separate LED die, which emits light when an electrical current passes through it. By mixing these three colors in different intensities, RGB LED SMDs can produce a wide range of colors. The key components of an RGB LED SMD include: 1. LED Die: The core of the LED, which emits light when an electrical current passes through it. 2. Phosphor: A material that converts the blue light emitted by the LED die into other colors, such as green and red. 3. Lead Frame: A metal frame that holds the LED die and connects it to the circuit. 4. Bonding Wire: A thin wire that connects the LED die to the lead frame. 5. Encapsulation: A protective layer that covers the LED die and bonding wire, preventing damage and improving heat dissipation.
