Aluminum SMD 5730 LED Lamp Circuit Board Copper Thickness 0.5oz 4.0oz

LED is an abbreviation for light-emitting diode. An LED is mostly a two-lead semiconductor device that emits light when current passes in a specific direction. Although LEDs start with devices that only emit low-intensity infrared light, this technology has been widely used in lighting for many years. Modern LEDs provide not only high intensity, very bright light but also different uses and use in various scenes, such as plant growth lights, car lights, street lights, traffic lights, shadowless lights in hospital operating rooms.

Soldering the LED chip to the PCB Board, as long as the PCB circuit is connected in some way, it will illuminate, which forms the LED PCB. LED PCBs typically also have a heat sink and ceramic pedestal to hold the circuit in place and allow the smooth operation of the channel. A heat sink is required because LEDs tend to generate a lot of heat, which can damage the PCB and the equipment that connects the circuits.

Because LED will produce a lot of heat, led PCB generally uses metal substrate as its production material. Metals with the ability to dissipate heat quickly have proved to be a better choice. Generally, whenever led PCB is designed, Aluminum PCB is preferred. Aluminum PCB usually also contains a thin layer of dielectric, which can dissipate heat faster.

In addition to general lighting, led PCB can also provide visible light, infrared, and ultraviolet light. Compared with other light sources, LED PCB can provide higher energy.
