As a structural component of electronic products, heat sinks cover a wide range of applications, including consumer electronics, servers, medical devices, electric energy, transportation, LED lighting products, etc., which may involve the use of heat sinks. The market for electronic products has a huge potential. 1. Analysis of market prospects of LED lighting and heat dissipating components industry (1) LED lighting cooling demand promotes LED lighting and heat dissipation industry development LED is optoelectronic device, only 10% to 40% of electric energy is converted into light energy during the working process, and the remaining electric energy is almost Both are converted into heat. 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 has 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 for the heat-dissipation component industry to open up the growth space LED lighting compared with traditional light sources such as incandescent lamps, fluorescent lamps, etc., in the energy saving, environmental protection, service life, color, volume, reaction time and many other advantages, LED lighting The replacement of traditional lighting sources 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 the largest 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 first 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, 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. 2 China's outdoor LED lighting market development The outdoor lighting market mainly includes road lighting, square lighting, stadium lighting, station dock lighting. Due to its particularity, road lighting is the first market for LED lighting to penetrate 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 the market with the highest 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 increase. The LED street light 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. 2. LED lighting cooling component industry competition pattern (1) LED lighting cooling market participation in the main competition of the LED lighting cooling market participants mainly include aluminum and other raw material suppliers, hardware processing plants and other external service providers, finished LED lighting manufacturers cooling Component production department, professional LED heat sink supplier, etc. Finished LED luminaire manufacturers The heat-dissipating component production department is the internal production department of LED luminaire manufacturers. It organizes the production of heat-dissipating components according to product design and process requirements for LED luminaire manufacturers to use for themselves. External service providers such as hardware processing plants are mainly engaged in metal processing business, providing middleware products for heat dissipation components. Professional thermal component suppliers have emerged with the specialized division of the LED lighting industry, providing complete thermal components or thermal solutions for finished LED luminaire manufacturers. Finished LED luminaire manufacturers' heat-dissipation component production department has a certain competitive relationship with professional heat-dissipation component suppliers. External service providers such as hardware processing factories and other market participants mainly cooperate with each other. However, in some subdivided products with low heat dissipation requirements and relatively simple processes, they may also provide finished products of heat dissipation components to LED lighting manufacturers as foundries. Therefore, there is also a certain competitive relationship with the manufacturer of the heat-dissipating components of the finished LED lamp manufacturers and the professional heat-dissipating component suppliers. (2) Industry competition LED lighting applications and heat dissipation technology requirements are different, which makes the LED lighting and heat dissipation component industry show different competitive characteristics. 1 Low-power LED lighting components competition in the industry Small power LED lighting products have low power consumption and low heat generation, which mainly depends on the heat dissipation of the lamp housing. There are a large number of lighting or hardware processing enterprises engaged in the processing of small-power LED lighting products, and the production is relatively scattered, and the number of enterprises with large-scale supply capacity is small. The rapid increase in the market penetration rate of low-power LED lighting products has also attracted a large number of home-based companies to infiltrate into the field of low-power LED lighting, which has intensified competition in this industry. At present, most enterprises in the low-power LED lighting and heat-dissipating component industry are not high in technology and relatively backward in manufacturing process, and they do not pay much attention to the heat dissipation design of lamps. The quality of products is not high. These enterprises are mainly involved in the competition of low-end products. 2 High-power LED lighting and heat-dissipating components industry competition The high-power LED lighting products are rich in specifications and specifications, mainly as energy-saving alternatives to traditional metal halide lamps, high-pressure sodium lamps and other lighting sources, and are currently in the market introduction period. The power of a single-chip LED light source on the market is usually around 1-5W, and the light output is only a few hundred lumens. The LED is really used in public places such as road lighting. The luminous flux of the LED light source must reach several thousand or even tens of thousands of lumens. The light output cannot be achieved by a single chip, so in LED lighting applications, two main types of lamps have been formed to meet the corresponding illumination brightness requirements. One is an array type LED lamp, which adopts a combination matrix structure lamp design concept, and arranges a plurality of single-chip LED light sources in a matrix form to form a large light-emitting panel; the other is an integrated LED lamp, which mainly adopts multiple A chip-integrated LED light source that closely mounts multiple LED chips on the same metal substrate to meet the lighting needs of public places. The structure of the two types of LED luminaires differs depending on the arrangement of the LED chips, and the requirements for the light distribution curve, the space occupied, and the heat dissipation technology. Array LED lamps have large illumination areas and are limited in application. They are currently used in lighting fields such as street lamps and tunnel lights. Because the technical requirements for heat dissipation are relatively low, the technical implementation scheme is relatively simple. Some large LED lamp manufacturers and professional LED lighting and heat dissipation component manufacturers have technical strength and fierce competition. The integrated LED luminaire is easy to perform light distribution and light effect management. Its illumination effect is close to that of traditional light source, and its application range is wide. It is the future development direction of high-power LED lighting, but the heat dissipation technology requirements are higher than array high-power LED lamps. The heat dissipation problem is difficult to solve and development is limited. The solution to the heat dissipation problem is a prerequisite for the promotion and application of integrated high-power LED lighting products. The technical threshold is relatively high. At present, there are not many enterprises that have integrated high-power LED lighting cooling technology and solutions, and enterprises that provide heat-related products and services. The number is also small and the overall level of competition is low. It is expected that with the advancement and popularization of heat dissipation technology and the outbreak of high-power LED lighting market, enterprises entering the field of high-power LED lighting and cooling will increase, and the competition will become increasingly fierce.
