With the development of the world economy, green and energy-saving development is the mainstream of today's world development. LED conforms to the trend of the times and has emerged in the field of lighting. LED lighting has driven the market of the LED lighting cooling component industry.

1. Market prospect analysis of LED lighting cooling component industry

(1) LED lighting heat dissipation demand promotes the development of LED lighting heat dissipation industry

LEDs are optoelectronic devices, only 10% to 40% of the electrical energy is converted into light energy during its operation, and almost all the rest of the electrical energy is converted into heat energy. For LED lamps for lighting, the amount of lumens required in a specific area may exceed thousands or tens of thousands of lumens. The heat generated by the LED working process is concentrated in the small chip, and the temperature of the chip increases, causing non-uniform thermal stress. The distribution, chip luminous efficiency and phosphor 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 lighting system, the problem of heat dissipation is even more serious. Solving the problem of heat dissipation has become a prerequisite for LED lighting, especially high-power LED lighting applications.

Optimizing the structural design of lamps and using external cooling systems such as radiators are effective measures to solve the heat dissipation problem of LED lighting products. At present, the common LED lighting products on the market are mainly composed of LED light source, driving power supply, radiator, and other structural parts. The radiator and other structural parts together constitute the heat dissipation component of LED lighting products. The heat dissipation component undertakes the heat dissipation function, and at the same time, as the lamp housing, it also undertakes the protection function of the electronic device, so as to prevent it from being contaminated with dust, liquid or unnecessary contact with other substances. A typical LED luminaire structure is shown below:

In recent years, with the widening range of LED lighting applications, the LED lighting industry has developed rapidly, and the industrial division of labor has also made great progress. LED lighting manufacturers with channel advantages purchase heat dissipation components, LED light sources, and drive power from suppliers, and then assemble them into finished lamps to sell to their downstream customers. The growth in demand from lighting manufacturers and other customers has driven the continuous development of the LED lighting cooling component industry.

(2) Market growth of LED lighting industry opens up growth space for heat dissipation component 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, response time, etc. 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. Driven by the decline in costs, the price of LED lighting products has also shown a sharp decline in the past two years; on the other hand, governments have also banned incandescent lamps, provided R&D subsidies, equipment A series of policy measures such as subsidies, terminal subsidies, targeted procurement and encouragement of contract energy management models support the LED lighting industry. Driven by these two aspects, the global penetration rate of LED lighting has been greatly improved.

While the global LED lighting penetration rate has increased significantly, the global LED lighting market scale has also shown a rapid growth trend. According to the data of Digitimes, a market research organization in Taiwan, in 2009, the global LED lighting market scale was 1.75 billion US dollars, and in 2010 it was 3.717 billion US dollars, with a growth rate of 112%; in 2012, the market scale exceeded 10 billion US dollars, reaching 12.148 billion USD; In 2015, the global LED lighting market size was 29.908 billion USD, with a compound annual growth rate of 60.49% from 2009 to 2015.

It is estimated that the size of the global LED lighting market in 2016 will reach 34.64 billion US dollars, an increase of 15.8% over 2015, and the global LED lighting market is growing rapidly.

At present, my country's LED lighting market has also entered a growth stage. With the improvement of the cost performance of LED chips, the development of comprehensive light distribution design, drive control, heat dissipation and other technologies, as well as the improvement of various LED lighting solution systems for different light environment application characteristics With maturity, LED lighting has penetrated more and more into the field of traditional lighting, and has gradually been widely used and promoted. In 2014, the output of domestic LED lighting products in my country was about 1.67 billion, and the domestic sales volume was about 750 million. The domestic market share of LED lighting products (the number of domestic sales of LED lighting products/the total domestic sales of lighting products) reached 16.4%, which is higher than that in 2013. 8.9% increased by about 7 percentage points, of which commercial lighting showed a blowout growth, public lighting grew rapidly, and home lighting began to start.

In 2015, the global acceleration of the phase-out of incandescent lamps, LED has become the mainstream light source for lighting. In 2015, the output of domestic LED lighting products in my country was about 6 billion, and the domestic sales volume was about 2.8 billion. The domestic market share of LED lighting products reached 32%, an increase of about 15 percentage points over 2014. In 2016, my country's domestic LED lighting product output was about 8 billion, a year-on-year increase of 33%; domestic sales were about 3.8 billion, a year-on-year increase of 35%. The domestic market share of LED lighting products reached 42%, up 10 percentage points from 2015.

Development of China's indoor LED lighting market

The indoor lighting market includes factory lighting, shopping mall indoor lighting, hotel indoor lighting, office indoor 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 light sources for indoor lighting, while the prices of LED lighting products are high and are in the demonstration stage; The implementation of the policy of banning production of incandescent lamps in sequence, incandescent lamps will gradually disappear in the market, energy-saving lamps will occupy the main share, and the share of LED lighting products will also increase; the third stage: LED lighting products occupy the main market for indoor lighting Leading energy-saving lamps.

At present, my country's LED indoor lighting products are mainly used in commercial places, such as underground parking lots, supermarkets, hotels, etc., which are in the stage of transition from substitution to large-scale substitution. With the 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, thereby changing people's traditional daily lighting methods.

② Development of China's outdoor LED lighting market

The outdoor lighting market mainly includes road lighting, square lighting, sports field lighting, station and wharf lighting, etc.

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 the energy consumption of public transportation, LED street lights with obvious energy-saving benefits have been strongly encouraged and supported by public utilities. The government has begun to vigorously promote the construction of LED lighting demonstration projects in recent years, and promote LED The popularity of street lights. The road lighting market is the market with the highest penetration rate in the LED general lighting market segment. At present, the application in the branch and secondary roads is becoming more and more mature, but the application in the main road is still in the exploration period. In the future, as the penetration rate of LED street lights in the main road market increases , LED street lamp market space will be further released.

Compared with the road lighting market, outdoor lighting markets such as squares, stadiums, stations, and wharves have higher requirements for lighting effects, stability, quality and technology of lighting products. In these outdoor lighting fields, the penetration rate of LED lighting products is relatively low. Replacing traditional lighting also requires a process of in-depth market awareness. With the gradual maturity of power supply, chip, heat dissipation and other technologies, the continuous launch of reliable, stable, high-performance high-power LED outdoor lighting products, and the further deepening of market awareness, LED lighting is widely used in outdoor fields such as squares, stadiums, stations, and docks. applications are expected to usher in explosive growth.

2. Competitive landscape of LED lighting cooling components industry

(1) Competitive relationship among participants in the LED lighting cooling market

The main players in the LED lighting heat dissipation market mainly include raw material suppliers such as aluminum, outsourcing service manufacturers such as hardware processing factories, heat dissipation component production departments of finished LED lighting manufacturers, and professional LED heat dissipation component suppliers.

The heat dissipation component production department of the finished LED lamp manufacturer is an internal supporting production department of the LED lamp manufacturer, which organizes the production of heat dissipation components according to the product design and process requirements for the LED lamp manufacturer's own use. Outsourcing service providers such as hardware processing factories are mainly engaged in metal processing business and provide middleware products for heat dissipation components. Professional cooling component suppliers emerged with the specialized division of labor in the LED lighting industry, providing a complete set of cooling components or cooling solutions for finished LED lighting manufacturers.

There is a certain competitive relationship between the heat dissipation component production department of the finished LED lamp manufacturer and the professional heat dissipation component supplier. Outsourcing service manufacturers such as hardware processing factories and other market participants mainly have cooperative relations, but in some product segments with low heat dissipation requirements and relatively simple processes, they may also serve as foundries to provide LED lighting manufacturers with finished products of heat dissipation components. Therefore, there is also a certain competitive relationship with the heat dissipation component production department of the finished LED lamp manufacturer and the professional heat dissipation component supplier.

(2) Industry competition

LED lighting applications and heat dissipation technology requirements are different, which makes the LED lighting heat dissipation component industry present different competitive characteristics.

① Low-power LED lighting heat dissipation component industry competition

Low-power LED lighting products have low power consumption and low heat generation, and mainly rely on the heat dissipation of the lamp housing. There are a large number of lighting or hardware processing enterprises engaged in the processing of low-power LED lighting product lamp housings, and the production is relatively scattered, and the number of enterprises with large-scale supply capacity is relatively small. The rapid increase in the market penetration rate of low-power LED lighting products has also attracted a large number of home-based workshop enterprises to enter the field of low-power LED lighting processing, which has intensified competition in this industry. At present, the vast majority of enterprises in the low-power LED lighting heat dissipation component industry have low technical level, relatively backward manufacturing processes, and do not pay attention to the heat dissipation design of lamps, and the product quality is not high. Such enterprises mainly participate in the competition of low-end products.

② Competition situation of high-power LED lighting cooling components industry

High-power LED lighting products are rich in varieties and specifications, mainly as energy-saving substitutes for traditional metal halide lamps, high-pressure sodium lamps and other lighting sources, and are currently in the market introduction period.

The power of single-chip LED light sources on the market is usually around 1-5W, and the light output is only a few hundred lumens. However, when LEDs are really used in public places such as road lighting on a large scale, the luminous flux of LED light sources must reach thousands or even tens of thousands of lumens, which is so high. Therefore, in LED lighting applications, in order to meet the corresponding lighting brightness requirements, two main types of lamps are formed. One is an array LED lamp, which adopts the design concept of a combined matrix structure lamp, and arranges multiple 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 uses multiple Chip-integrated LED light source, which closely assembles multiple LED chips on the same metal substrate to meet the lighting brightness requirements of public places.

The structure of the two types of LED lamps differs in light distribution curve, occupied space and heat dissipation technical requirements due to the different arrangement of LED chips. Array-type LED lamps have a large luminous area and are limited in use. Currently, they are mostly used in lighting fields such as street lamps and tunnel lamps. Because the technical requirements for heat dissipation are relatively low and the technical implementation scheme is relatively simple, some large LED lighting manufacturers and professional LED lighting heat dissipation component manufacturers have technical strength, and the competition is fierce.

Integrated LED lamps are easy to carry out light distribution and light efficiency management. Their lighting effects are close to traditional light sources and have a wide range of applications. They are the future development direction of high-power LED lighting. However, the heat dissipation technology requirements are higher than that of array high-power LED lamps. The heat dissipation problem is difficult to solve, and the development is limited to a certain extent. Solving the heat dissipation problem is a prerequisite for the promotion and application of integrated high-power LED lighting products, and the technical threshold is relatively high. At present, there are not many companies that master integrated high-power LED lighting heat dissipation technology and solutions, and companies that provide heat dissipation related products and services. There are also fewer numbers, and the overall level of competition is lower.
