We are a professional LED PCB manufacturer and assembler in China, In this article, we would like to introduce in detail what is LED PCB, the materials used in manufacturing and LED circuit boards manufacturing, the application of LED Printed Circuit Boards and so on.
In China, there are many PCB manufacturers and suppliers. Jinghongyi PCB is one of the LED PCB Board manufacturers. We only provide LED PCB fabrication services. LED PCB design is not our specialty and business scope.
LED PCB has many other names, such as LED PCB board, LED circuit, LED Circuit Board, led printed circuit boards, PCB board for LED.
In a sense, LED PCB and aluminum PCB belong to the same kind of PCB products, because their uses and materials are mostly the same.
With the popularization and widespread use of industrial lighting and civil lighting, whether outdoor or indoor, family or commercial buildings and factories, lighting provides the guarantee of its normal operation.
Of course, nowadays, with the development of human society, environmental pollution has become a difficult problem in the world. In order to reduce the consumption of coal, such as coal used for power generation in thermal power plants, coal combustion pollutes the atmosphere very seriously. In order to save energy and protect the environment, LED lights and previous lighting methods have great advantages, except for energy. Besides providing brighter lights, it also contributes to environmental protection.
LED circuit board is a kind of printed circuit board.
Both LED aluminium PCB and FR-4 fiberglass circuit board belong to PCB. To say differently, only compare LED aluminium substrate with FR-4 fiberglass circuit board.
LED aluminium substrate is printed on the surface of aluminium material with better thermal conductivity, and then weld electronic components on it.
The voltage drop across an LED is approximately constant over a wide range of operating current; therefore, a small increase in applied voltage greatly increases the current.
Very simple circuits are used for low-power indicator LEDs. More complex, current source circuits are required when driving high-power LEDs for illumination to achieve correct current regulation.

Metal core PCBs are often chosen for LED applications because they have enhanced heat dissipation capabilities. In particular, aluminium is usually used to make circuit boards for LED lamps. Aluminum substrates usually consist of thin layers of thermal conductive dielectrics that can be transported and have much more efficient heat dissipation than conventional rigid PCBs.
Compared with other electronic components, LED generates more heat, which requires PCB to heat very well. For this special feature, Metal Core PCB is often used in LED circuit boards, especially Aluminum Core PCB .
The following is the heat dissipation capacity of PCB plates of different materials, from weak to strong

With the popularity of devices such as smart phones and tablets, it is very convenient to read e-books on these devices, but many people still like the unique texture of traditional paper books. However, there is a problem with reading paper books: Paper itself does not emit light, and it requires good lighting. During the day, it seems to be inconvenient at night, especially when others in the same room are already sleeping.
To solve this problem, a Japanese manufacturer provided a lighting tool called LightWedge 2.0. It looks like a bookmark made of plastic, but with a giant piece of organic glass. The side of the LED lights will emit a soft light, through the plexiglass to illuminate the entire page of the book, the display effect is similar to a Kindle like paper books, and will not bother other people.
LightWedge2.0's volume weight is not large, measurements are 165 × 225 × 11 mm, weight 220 grams, can be used as a bookmark in the book, but also very easy to carry. The built-in lithium battery can support 15 hours of reading. When the battery runs out, it can be connected to the computer with a USB cable to charge.

The relationship between LED and PCB
The Printed Circuit Board is a genius innovation of circuit technology, laying less space and materials for more complex and large-scale circuits. The printed circuit board is such an important invention in circuit technology because it makes electrical and electronic components smaller, more flexible and more precise. For example, FPC( Flexible PCB ), Multilayer PCB , BGA PCB , rigid- Flex PCB and so on.
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 circuit. 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.
LED PCB board Introduction
LED PCB Meaning
LED PCB Board manufactureing
In electronics, an LED circuit or LED driver is an electrical circuit used to power a light-emitting diode (LED). The circuit must provide sufficient current to light the LED at the required brightness, but must limit the current to prevent damaging the LED.
An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means.
1. FR4, common PCB board material;
2. Alumina substrate;
3. There is no doubt that the thermal conductivity of ceramic PCB is the best among many materials;
4. The thermal conductivity of alumina ceramic circuit board can be about ten times that of the aluminum substrate;
5. The thermal conductivity of Slyton aluminum nitride ceramic circuit board is ten times higher than that of alumina;
In this kind of ultra-high thermal conductivity, LED light attenuation will be greatly weakened, and its service life will be greatly increased.
