LED or light-emitting diode is a semiconductor device that will emit light even when a small current passes through them. Compared to conventional lighting systems, it is not only different in design, but also different in the way it creates light. Traditional lamps emit light by connecting to a power source with a wire. The heat generated by heati...
The core component of LED lights is a tiny chip with a layer of semiconductor layer. One or multiple chips are mounted on a heat sink covered by a lens, which results in a device 7 to 9 millimeters thick that has a variety of usages. The LEDs are then mounted on a programmed circuit board that can control the light, including light intensity, light...
More creativity is needed in the design of LED lights. Before LED light manufacturing, there are some optical properties such as the color temperature, brightness and efficiency of the LED lamp should be determined. The size of the diode, the semiconductor materials, the type of impurities added and the thickness of the diode layers are all the fac...
Raw materials required for LED light manufacturing or assembly (for 10W LED-based lighting system) are listed as follows: 1. LED boards and LED chips 2. Metallic cap holder 3. Heat sinks 4. Rectifier circuit with filter 5. Plastic body 6. Reflector plastic glass 7. Connecting wire 8. Soldering flux 9. Packaging materials 10. Miscellaneous parts
LED light manufacturing or assemblyis a complicated task, but before you get started, you need master some basic knowledge and skills about the manufacturing process. There are a wide selection of equipment for LED light manufacturing. However, the production department should select the right equipment depending on the specific type of LED lights ...
Wafer Fabrication
The first is the fabrication of a semiconductor wafer. The material composition to be used is determined by the color of LED light, whether gallium arsenide (GaAs), gallium phosphide (GaP) or other composite materials. To mix these materials with elements such as phosphorus, gallium and arsenic, a high-temperature and high-pressure chamber is required where the materials are then purified, liquefied and pressed together to form a solution. To prevent the materials from escaping from the chamb...
Adding Epitaxial Layers
The following LED light manufacturing process is the addition of epitaxial layers. As the semiconductor layers are added to the wafer surface, the wafer layers are built up over time. Some impurities or dopants need to be added in the process, which is called Liquid Phase Epitaxy method or LPE. This technique allows the epitaxial layers with the same crystalline orientation as the underlying substrate to be biased during the deposition of the molten GaAsP. The wafer is mounted on a graphite s...
Adding Metal Contacts
Metal contacts should be defined on the wafer at the design stage. The contact pattern is determined by the combination of diodes. A light-sensitive compound called photoresist is used to clone or reproduce the contact patterns. As the wafer spins around, the resist is distributed evenly over the surface in droplets and is quickly harden by heating at 100 degrees Celsius. The photoresist mask is then placed on the wafer to duplicate the mask pattern, while exposing the resist under ultraviole...

The most commonly used metals are aluminium, nickel, chrome, cast iron and stainless steel. Basically, metals can be processed very flexibly and impress with their long durability. In addition, metal materials can be completely recycled.
Sep 20, 2024 · In lighting manufacturing, raw materials are used to produce light fixtures and lamps. The most common lighting raw materials include the following: Metals.
Apr 17, 2022 · LEDs, incandescent, and fluorescent lights produce light in different ways, which means they differ in design and mode of operation. Traditional lights produce light by passing an electric current through a wire until the wire is hot enough to emit light.
Aug 31, 2022 · How an LED Light Works. Diodes are made from semiconductor material. This semiconductor material is composed of crystalline material and requires impurities to conduct electricity. These impurities are added to the semiconductor material later in the manufacturing process.
The particular material composition—GaAs, GaP, or something in between—is determined by the color of LED being fabricated. The crystalline semiconductor is grown in a high temperature, high pressure chamber. Gallium, arsenic, and/or phosphor are purified and mixed together in the chamber.
