The market for electronic products has a huge potential.

1. Analysis of market prospects of LED lighting and heat dissipation components industry

(1) LED lighting cooling demand promotes LED lighting cooling industry development

LEDs are optoelectronic devices, in which only 10% to 40% of the electrical energy is converted into light energy, and the rest of the electrical energy is converted into thermal energy. For LED luminaires for lighting, the amount of lumens required in a particular area may exceed thousands of lumens or tens of thousands of lumens. The heat generated by the LED process is concentrated in a chip of small size, and the temperature of the chip rises, causing non-uniform thermal stress. The distribution, chip luminous efficiency and fluorescent powder lasing efficiency decrease; when the temperature exceeds a certain value, the device failure rate increases exponentially. When multiple LEDs are densely arranged to form a white light illumination system, the heat dissipation problem is more serious. Solving heat dissipation has become a prerequisite for LED lighting, especially for high-power LED lighting applications.

Optimizing the design of the luminaire structure and using an external cooling system such as a radiator is an effective measure to solve the heat dissipation problem of LED lighting products. At present, LED lighting products commonly used in the market are mainly composed of LED light source, driving power source, heat sink, and other structural parts. The heat sink and other structural components together constitute a heat-dissipating component of the LED lighting product. The heat-dissipating component is responsible for the heat-dissipating function, and at the same time, as the lamp housing, it also assumes the protection function of the electronic device, so as to avoid contamination with dust, liquid or unnecessary contact with other substances. A typical LED luminaire structure is as follows:

In recent years, with the wider application range of LED lighting, the LED lighting industry has developed rapidly, and the industrial division of labor has also made great progress. LED luminaire manufacturers with channel advantages purchase heat dissipation components, LED light sources, and drive power supplies from suppliers, and then assemble them into finished lamps to sell to their downstream customers. The growth in customer demand such as luminaire manufacturers is driving the continued development of the LED lighting and cooling components industry.

(2) LED lighting industry market growth opens up space for the thermal components industry

Compared with traditional light sources such as incandescent lamps and fluorescent lamps, LED lighting has advantages in energy saving, environmental protection, service life, color, volume, and reaction time. The replacement of traditional lighting sources by LED lighting is an inevitable trend in the development of the lighting market.

In recent years, on the one hand, the cost of LED devices has dropped significantly. Under the impetus of cost reduction, the price of LED lighting products has also shown a sharp decline in the past two years. On the other hand, governments have also disabled incandescent lamps, provided research and development subsidies, and equipment. A series of policy measures such as subsidies, terminal subsidies, targeted procurement and incentives for contract energy management support the LED lighting industry. Driven by these two aspects, the global LED lighting penetration rate has been greatly improved.

At the same time as the global LED lighting penetration rate has increased significantly, the global LED lighting market has also shown a rapid growth trend. According to data from Taiwan market research firm Digitimes, in 2009, the global LED lighting market was 1.75 billion US dollars, and in 2010 it was 3.17 billion US dollars, with a growth rate of 112%. In 2012, the market size exceeded 10 billion US dollars, reaching 12.148 billion. In 2015, the global LED lighting market was US$29.908 billion, with an average annual compound growth rate of 60.49% from 2009 to 2015.

It is estimated that the global LED lighting market will reach US$34.64 billion in 2016, an increase of 15.8% compared with 2015. The global LED lighting market is growing rapidly.

At present, China's LED lighting market has also entered the growth stage. With the improvement of the cost performance of LED chips, the development of integrated light distribution design, drive control, heat dissipation and other technologies and the improvement of various LED lighting solutions for different light environment applications. With maturity, LED lighting has penetrated into the traditional lighting field more and more, and it has gradually been widely applied and popularized. In 2014, China's domestic LED lighting products output was about 1.67 billion, domestic sales were about 750 million, and the domestic market share of LED lighting products (the domestic sales of LED lighting products/the total domestic sales of lighting products) reached 16.4%, compared with 2013. 8.9% rose by about 7 percentage points, of which commercial lighting showed a spurt of growth, public lighting grew rapidly, and home lighting began to start.

In 2015, the global accelerated elimination of incandescent lamps, LED has become the mainstream source of lighting. In 2015, China's domestic LED lighting products output was about 6 billion, domestic sales were about 2.8 billion, and the domestic market share of LED lighting products reached 32%, an increase of about 15 percentage points over 2014. In 2016, China's domestic LED lighting products output was about 8 billion, up 33% year-on-year; domestic sales were about 3.8 billion, up 35% year-on-year. The domestic market share of LED lighting products reached 42%, an increase of 10 percentage points over 2015.

China's indoor LED lighting market development

The indoor lighting market includes factory lighting, shopping mall interior lighting, hotel interior lighting, office building interior lighting, stadium lighting, and home lighting. In terms of market size, the indoor lighting market will grow into a larger market due to the wide range of application groups.

The development of the LED indoor lighting market can be roughly divided into three stages. The front stage: incandescent lamps, fluorescent lamps and energy-saving lamps are the main sources of indoor lighting, while the price of LED lighting products is high and in the demonstration stage. The second stage: with the world The implementation of the incandescent prohibition policy for incandescent lamps will be implemented in sequence, incandescent lamps will gradually disappear in the market, energy-saving lamps will occupy a major share, and the share of LED lighting products will also increase; the third phase: LED lighting products occupy the main market for indoor lighting, Leading energy-saving lamps.

At present, China's LED indoor lighting products are mainly used in commercial places, such as underground parking lots, supermarkets, hotels, etc., in the stage of substitution and acceptance to scale replacement. With the continuous deepening of Chinese consumers' awareness of LED lighting products, LED indoor lighting has begun to enter the field of home lighting with huge market space, thus changing people's traditional daily lighting methods.

The outdoor lighting market mainly includes road lighting, square lighting, stadium lighting, station dock lighting and so on.

Due to its particularity, road lighting is a market where LED lighting has penetrated into the traditional lighting field. Due to the gradual increase in energy consumption of public transportation, LED street lights with obvious energy-saving benefits have been strongly encouraged and supported by the public utilities sector. In recent years, the government has vigorously promoted the construction of LED lighting demonstration projects, and promoted LEDs by providing preferential policies such as government subsidies. The popularity of street lamps. As a market with high penetration rate in the LED general lighting segment, the road lighting market is increasingly mature in the application of trunk roads, but the application in the main road is still in the exploration period. In the future, the penetration rate of LED street lamps in the main road market will follow. As the upgrade, the LED streetlight market space will be further released.

Compared with the road lighting market, the outdoor lighting market such as squares, sports fields, stations, docks and other lighting products have higher requirements for lighting effects, stability, quality and technology. In these outdoor lighting fields, the penetration rate of LED lighting products is relatively low. Replacing traditional lighting also requires a process of deeper understanding of the market. With the gradual maturity of power, chip, heat dissipation and other technologies, the continuous introduction of reliable, stable and high-performance high-power LED outdoor lighting products, as well as further deepening of market awareness, LED lighting in outdoor areas such as squares, sports fields, stations, terminals, etc. The application is expected to usher in explosive growth.
