How to develop the LED industry without "short-lived emperor"

It’s another year’s inventory. At the beginning of this year, the overall rise in LED home lighting caused by a small rebound in ceiling lamps has led the industry to believe that 2014 is the "outbreak year" for LED lighting. Many phenomena seem to prove this too. Such as Ali, BYD, Midea and other cross-border capital, the increase in bulk imports and export orders and the national and local governments actively promote energy-saving emission reduction, vigorously advocate the use of LED lighting products, all kinds of positive phenomena really let the LED emperor generally sit in the lighting industry Dragon chair.

However, it is slow, although the emperor is glamorous, but there are many emperors who are short-lived in history. Like Tongzhi, Guangxu is not long. The LED industry in 2014 is also like a short-lived emperor. Soon after the "thumbation" at the beginning of the year, when the industry was laughing and ready to meet the market explosion, just two months later, I heard the market whining.

National LED product sales suddenly fell into a sustained weakness. This makes producers and sellers complain. The main reason is that the overall domestic economic situation has weakened, the growth of the upstream real estate industry has slowed down and engineering projects have decreased, domestic monetary tightening, and loans have been difficult. All kinds of unfavorable factors have swept the LED lighting industry in the "expansion period", the lighting market is deserted, the peak season is not prosperous, and the off-season is very weak.

The market is so sluggish, but the competition is fierce. Conventional varieties such as bulbs, digital tubes, fluorescent tubes, lamp strips, downlights, and spotlights are as low as cabbage prices. Tens of thousands of LED companies spend several times more manpower, material resources, and energy to grab the lighting market cake than in previous years. Killing the market is a red sea, but the cost is calculated, almost no money is earned, and even more sales, the greater the loss. After a few rounds, some companies were defeated because they were powerless. In the second half of the year, companies like Fengguang began to run, and the tide of closure began to appear.

Many people in the industry complain to the author that only a small number of companies or distributors have made money this year. But both production and sales were lower than last year, and even the same as last year's sales were few. that's the truth. This year, hundreds of millions of enterprises in Shenzhen, Zhongshan and Dongguan have closed down or run, so that people in other industries "talk about LED color change." By the end of the year, industry news was almost exclusively monopolized by “LED Run News”.

But there are also some companies that have weathered the storm. Become a "a little red in the green bush".

The reason why these enterprises have the ability to resist risks is mainly: First, the technology is excellent; Second, there are channels both at home and abroad, and third, the capital is strong. For companies that make money this year, profits are mainly from exports. Those companies that used to be domestic channels alone have been sad this year.

Therefore, to be an emperor must have a hard work, otherwise the risk will become a short-lived ghost. In particular, the current market continues to be deserted, and the market may be even harder to do next year. In particular, companies must practice their skills. To save social order, we must improve the cultural quality of the whole people. Therefore, now we should give ourselves some time to study. Only if you become a true reading person, you will be spiritually purified and sublimated. If everyone does this, the whole society will be All right.

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.
LED Printed Circuit Board
LED is an abbreviation for light-emitting diode. An LED is essentially a two-lead semiconductor device that emits light when current passes in a certain 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 not only provide high intensity, very bright light but also different uses and use in different 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 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.

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 board Introduction


LED PCB has many other names, such as LED PCB board, LED circuit, LED circuit boardled 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.

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.

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. 

Kinds of LED PCB Circuit Board

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.

An LED PCB board tends to generate a high volume of heat, making it difficult to cool via traditional means.

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

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.
