This significant improvement in luminous efficiency is mainly due to the continuous optimization of LED chip materials and manufacturing processes.

Technology of 8mm Power LED

The 8mm power LED is a type of high-power LED with a diameter of 8mm. It is composed of a LED chip, a heat sink, a lens, and an encapsulant. The core component of the 8mm power LED is the LED chip, which is a semiconductor device that emits light when an electric current passes through it. The quality of the LED chip directly affects the performance of the 8mm power LED. 1. LED Chip Technology The LED chip is the core component of the 8mm power LED. Its quality is determined by the following factors: - Material: The commonly used materials for LED chips are gallium nitride (GaN), gallium phosphide (GaP), and silicon carbide (SiC). Among them, GaN has the best performance in terms of luminous efficiency and color purity. - Structure: The structure of the LED chip mainly includes single-layer, double-layer, and multi-layer. The multi-layer structure can improve the luminous efficiency and color purity of the LED chip. - Growth process: The growth process of the LED chip directly affects the quality of the chip. The commonly used growth processes include molecular beam epitaxy (MBE), metal-organic chemical vapor deposition (MOCVD), and hydride vapor phase epitaxy (HVPE). 2. Heat Sink Technology The heat sink is an important part of the 8mm power LED, which is responsible for dissipating the heat generated by the LED chip. The commonly used heat sink materials are aluminum, copper, and zinc alloys. The design of the heat sink can affect the heat dissipation efficiency of the 8mm power LED. 3. Lens Technology The lens is used to focus the light emitted by the LED chip, so as to improve the luminous efficiency and beam quality of the 8mm power LED. The commonly used lens materials are acrylic, polycarbonate, and glass. 4. Encapsulation Technology The encapsulant is used to protect the LED chip and improve its stability. The commonly used encapsulants are epoxy, polyimide, and silicone.
