What is an LED PCB? What are the application fields of LED PCB?

LED is the abbreviation of light emitting diode, that is, semiconductor diode. The LED is soldered to the printed circuit board and is equipped with a chip that generates light through electrical connection. A heat sink and a ceramic base are used to connect the chips. There is no doubt that LED PCB is the core of LED lighting. One LED PCB is easy to generate a lot of heat, but it is difficult to cool it with traditional methods. Metal core PCB is widely used in the application of LED because of its strong heat dissipation capacity, especially aluminum is often used in the PCB production of LED lamps. Generally, aluminum PCB contains a thin layer of thermal conductive medium material, which can transmit and dissipate heat much more efficiently than traditional rigid PCB.

At present, SMD packaging is the most widely used packaging form in LED applications. Generally speaking, the light emitted by a single LED component is limited. Therefore, one lamp will use multiple LED components to get enough light. Like other semiconductor devices, PCB is the best way to electrically connect LED components. A PCB with LED components is often referred to as an "LED PCB".

Advantages of LED

Lower power consumption: Replacing incandescent lamps with LED lamps can reduce power consumption by more than 80%.

Longer service life: The service life of LED can generally exceed 20000 hours, which can be used 24/7 in 3 years, 25 times longer than that of incandescent lamp. It can not only save costs, but also reduce the replacement frequency.

Higher efficiency: Incandescent lamps release more heat. LED lights can be reduced by up to 20%. This shows that unnecessary heating can be reduced while using more powerful LED lights.

Smaller size: Due to its small size, LED lights can be of various sizes and can be applied in different places. Manufacturers can add LEDs to everything, from electronic devices to cars, and even to traffic lights and signs on the road.

Environmental protection: Compared with other bulbs, LED lamps do not contain mercury. Therefore, LED has less impact on the environment and is easier to handle.
