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 emergence of new products and new technologies in the home appliance industry, the concept of consumption has been continuously upgraded, and awareness of energy conservation and environmental protection has been continuously enhanced. This objectively requires home appliance companies in China to timely adjust and revise the technology roadmap to meet market and social needs.
On August 2nd, the second meeting of the China Household Appliance Industry Technology Roadmap Revision Working Group sponsored by the China Household Electrical Appliances Association was held in Yantai, Shandong. Nearly 50 experts and technicians from home appliance-related companies, colleges, and research institutes attended the meeting. And participate in the discussion. The conference separately discussed the technical status, research direction, and technical bottlenecks of ice-washing products, and proposed the industrial development goals with 2015 and 2020 as the time nodes.
The meeting proposed that by 2015, China's overall market refrigerator efficiency should be increased by 30% compared to 2009, fixed-frequency compressor COP value increased by 10% compared with 2009, the thermal insulation performance increased by an average of 5% over the current level, and refrigerators The system should be optimized 5% compared to 2009; the energy efficiency of the inverter room air conditioner is 20% higher than that of 2010, and the coefficient of performance (COP value, standard operating conditions) of the fixed frequency air conditioner compressor is increased to 3.2 or higher on average, and the trinity machine is formed. Mass production; mainstream wave wheel double barrel washing machine, mainstream wave wheel automatic washing machine, mainstream drum type automatic washing machine reaches GB12021.4 national standard energy efficiency level 2, mainstream drum type washing and drying machine reaches GB/T23118 GB standard A power consumption , water consumption requirements.
By 2020, the overall energy efficiency of refrigerators in the overall market will increase by 20%, the use of inverter compressors will account for more than 10%, the COP of fixed-frequency compressors will increase by 5% over 2015, and the energy efficiency of inverter room air conditioners will reach 2020. Further increase of 20%, the proportion of new products reached 20%; mainstream drum washing machine, wave wheel automatic washing machine, drum type washing and drying machine all reach GB12021.4 national standard energy efficiency level 1 power consumption, water consumption requirements.
The conference pointed out that the refrigerator products must ensure environmental protection in the production process and at the same time ensure the environmental protection of production materials. By 2015, the consumption of HCFC-22 in the air-conditioning industry will be reduced by 10% in 2009 and 2010 average levels. Technology industrialization; 30% increase in floor area ratio of washing machines, 20% increase in recycling and reusability, 15% increase in material utilization rate, 15% increase in component modularity, and a reference floor area ratio of washing machine products in 2015 by 2020 Another 15% increase, 10% increase in recycling and reusability, 10% increase in material utilization, and 15% increase in component modularity.
Participants also called for the home appliance industry to strengthen self-discipline in the industry and put an end to short-sighted behavior such as damage to energy efficiency and corporate reputation.
The most comprehensive introduction of LED PCB
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.
