|1, LED lighting, heat dissipation component (1) the LED lighting industry market prospect analysis cooling demand LED lighting radiator industry development is LED optoelectronic components, its working process is only 10% to 40% of the electric energy into light energy, almost all the rest of the electrical energy is converted into heat energy.For LED lighting lamps and lanterns, under the specific area of the required amount of lumens may exceed lumens thousands and thousands of lumen or the working process of the LED heat focused on the chip size is small, the chip temperature, thermal stress caused by non-uniform distribution, chip light-emitting efficiency and fluorescent powder blaster efficiency decline;When the temperature exceeds a certain value, the device's efficiency increases exponentially.The dissipation of heat is more serious when multiple leds form a white light system.The solution to heat dissipation has become a prerequisite for LED lighting, especially for high-power LED lighting applications.It is effective to optimize the structure design and use the external cooling system such as radiators to solve the heat dissipation problem of LED lighting products.Common LED lighting products on the market at present is mainly composed of LED light source, the drive power supply, radiators and other structural parts, radiator and other heat dissipation component structure constitute LED lighting products.The heat dissipation module assumes the heat dissipation function, and also takes the electronic device protection function as the lamp housing, so as to avoid the contamination of dust, liquid or unnecessary contact with other substances.A typical structure of LED lighting is shown below: in recent years, with the application of LED lighting, LED lighting industry has developed rapidly and the division of labor has made great progress.The manufacturers of LED lamps with channel advantages purchase heat dissipation module, LED light source and power supply respectively to suppliers, and then assemble the finished lamps to sell to their downstream customers.The growth of consumer demand such as the manufacturer of lamps and lanterns promotes the continuous development of LED lighting cooling component industry.(2) the LED lighting industry market growth space open for heat dissipation component industry growth LED lighting, compared with incandescent lamp, fluorescent lamp etc traditional lighting in energy saving, environmental protection, service life, color, has the advantage in many aspects, such as volume, reaction time, the LED lighting to replace traditional lighting sources are lighting market development inevitable trend.In recent years, on the one hand, the cost of LED components has decreased significantly, LED by the cost reduction, the price of LED lighting products has declined sharply in the past two years.On the other hand, governments by disabling incandescent lamp, also provide r&d subsidies, subsidies equipment and terminal, directional procurement and encourage contract energy management mode and a series of policy measures to support the LED lighting industry.The global LED illumination penetration rate has been greatly improved under the joint drive of these two aspects.At the same time, the global LED lighting market is increasing rapidly and the global LED lighting market is developing rapidly.According to data from Digitimes, the market research institute of Taiwan, the global LED lighting market in 2009 was us $1.75bn, with us $37.17 billion in 2010, with an increase of 112%.In 2012, the market size exceeded the $10 billion mark, reaching us $12.48 billion.In 2015, the global LED lighting market was $29.908 billion, with a compound growth rate of 60.49% from 2009 to 2015.The global LED lighting market is expected to reach $34.64 billion in 2016, up 15.8 percent from 2015 and the global LED lighting market is growing rapidly.At present, the LED lighting market has years, with the improvement of LED chip price, integrated light distribution design, drive control, cooling and other technical development and different light environment oriented application characteristics of various kinds of LED lighting solution system of perfect and mature, LED lighting has been more and more infiltrated traditional lighting area, gradually get extensive application and promotion.In 2014, domestic production of LED lighting products in China about 1.67 billion, domestic sales of about 750 million, LED lighting products in the domestic market share lighting products (LED lighting products for domestic sales quantity/total domestic sales) of 16.4%, higher than 8.9% in 2013 to about 7%, presents the blowout growth of commercial lighting, public lighting to the rapid growth of household lighting.In 2015, the global accelerated elimination of incandescent lamps, LED has become the mainstream light source of lighting.In 2015, there were about 6 billion LED lighting products in China, with about 2.8 billion domestic sales, and the domestic market share of LED lighting was 32 percent, up about 15 percentage points from 2014.In 2016, China's domestic LED lighting production was about 8 billion, up 33% year on year.Domestic sales volume was about 3.8 billion, up 35 percent year on year.The domestic market share of LED lighting products reached 42 percent, up 10 percentage points from 2015.China's indoor LED lighting market development Indoor lighting market including workshop lighting, interior lighting, hotel interior lighting, office buildings, indoor lighting, stadium lighting, home lighting, etc.In terms of market size, the indoor lighting market will grow into the largest market due to the wide range of application groups.LED indoor lighting market development can be roughly divided into three phases, the first stage: the incandescent lamp, fluorescent lamp and energy-saving lamp is the main light source, indoor lighting and LED lighting products, price is too high at the demonstration stage;Phase 2: with the implementation of the global ban on the prohibition of incandescent lamps, incandescent lamps will gradually disappear in the market, the energy saving lamps will be the main share, and the share of LED lighting products will be increased.Stage 3: LED lighting products occupy the main market of 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., which are in the phase of substitution acceptance to scale replacement.Along with our country the deepening of the consumer cognition of LED lighting products, LED indoor lighting began to enter the home lighting field of huge market space, so as to change the traditional way of daily lighting.The outdoor lighting market of outdoor LED lighting market in China mainly includes road lighting, square lighting, stadium lighting, station pier lighting, etc.Because of its particularity, road lighting is the first market for LED lighting to penetrate into traditional lighting.Due to the gradually rising public transportation energy consumption, obvious energy saving benefit of LED street light got strongly encourage and support the public sector, the government in recent years to push LED lighting demonstration project construction, through the provision of government subsidies and other preferential policies to promote the popularity of LED lights.Road lighting market as the highest permeability in the LED general lighting market segment market, currently in the application of the increasingly mature with time road, but in the main application is still in the exploration phase, the future as the LED street light in the main market penetration, LED street lamp market space will be further release.Compared to road lighting market, square, playground, station, wharf and other outdoor lighting markets of lighting lamp lighting effects, stability, quality and technical requirements higher, LED lighting products in the field of the outdoor lighting penetration rate is relatively low, the replacement of traditional lighting will also need a market further cognitive process.Such as power supply, chip, heat dissipation technology gradually mature, reliable, stable, high performance, high power LED outdoor lighting products continue to launch, and further deepen cognition by the market, LED lighting, outdoor playground, station, wharf, etc in the square in the field of application is expected to usher in explosive growth.2. LED lighting heat dissipation component industry competition participation main body (1) LED lighting heat market competition LED lighting heat market participation main body mainly include aluminum and other raw materials suppliers, hardware processing plants and other outsourcing services vendors, products of LED lamps and lanterns manufacturer heat dissipation component production departments, professional LED heat dissipation component suppliers, etc.Finished goods of LED lamps and lanterns manufacturer cooling components supporting the production department within the production department for the LED lamps and lanterns manufacturers, its organize production according to the product design and process cooling components, for the LED lamps and lanterns manufacturer for private use.Hardware factory and other foreign service providers are mainly engaged in the metal processing business, providing heat dissipation component middleware products.The professional heat sink component supplier is developed with the specialization of the LED lighting industry, providing full set of heat dissipation components or cooling solutions for finished LED lamps manufacturers.The production department of the finished LED lamp manufacturer has a competitive relationship with the professional heat dissipation component supplier.Hardware processing factory and so on service outsourcing vendor partnerships with other market participation main body mainly, but in some cooling requirements is low, the segmentation process is relatively simple products, it may also be as contract to provide heat dissipation component products of LED lamps and lanterns manufacturers, so heat dissipation component production department with finished goods of LED lamps and lanterns manufacturers and professional heat dissipation component suppliers also exists certain competitive relationship.(2) different requirements of LED lighting applications and heat dissipation technologies in the industry competition have LED to different competitive characteristics of LED lighting components industry.Small power LED lighting heat dissipation component industry competition situation small power LED lighting product power consumption small, heat low, mainly rely on the luminaire housing heat dissipation.The number of lighting or hardware processing enterprises engaged in the processing of small power LED lighting products is numerous, the production is more dispersed, and the number of enterprises with scale supply capacity is small.The rapid increase in the market penetration of small power LED lighting products has also attracted a large number of home-based enterprises into the processing field of small power LED lamps, which has intensified the competition in this industry.Currently the vast majority of small power LED lighting heat dissipation components industry enterprise technical level is not high, the manufacture technology is relatively backward, and the thermal design of lamps and lanterns is not seriously, the product quality is not high, this kind of enterprises participate in the competition of low-end products mainly.(2) high power LED lighting heat dissipation component industry competition situation High power LED lighting products specification is rich, mainly as a traditional metal halide lamp, high-pressure sodium lamp lighting light source such as energy-saving alternatives, is currently in its market.Single chip in the market of LED light source power usually around 1-5 w, only a few hundred light output lumens, and LED the real mass used in road lighting and other public places, the luminous flux of LED light source must reach thousands or even tens of thousands of lumen, such a high light output cannot be accomplished by single chip, therefore in LED lighting applications, to achieve the corresponding lighting brightness requirements, to form the two main types of lamps and lanterns.An array LED luminaire, which adopts the design concept of combination matrix structure, will make a large luminescent panel by using multiple single-chip LED light sources in the form of matrix spacing.The other is integrated LED lighting, which mainly USES multi-chip integrated LED light source, which is closely assembled on the same metal substrate to meet the lighting demand of public places.The two types of LED lighting structures are different in the layout of LED chips, which are different in|
the light distribution curve, occupancy space and heat dissipation technology.Array LED lamps have a large luminous area and some restrictions are applied to lighting, such as street lamps and tunnel lamps.Because of heat dissipation technology requirements are relatively low, technical implementation scheme is relatively simple, some large LED lamps and lanterns manufacturer and professional LED lighting heat dissipation component manufacturers have technical strength, the more competitive.Integrated LED lamps and lanterns is easy to light distribution and light efficiency management, the lighting effects with the traditional light source is relatively close, the wide range of applications, is the developing direction of high power LED lighting, but the heat dissipation technology requires higher than array type high power LED lamps and lanterns, heat dissipation problems difficult to solve, development.Heat dissipation problem is integrated the precondition of high power LED lighting products promotion use, technical threshold is higher, the master integrated high power LED lighting cooling technology and solutions for small number of enterprise, to provide products and services related to heat quantity is less, the overall competition level is low.With the development of heat dissipation technology and the explosion of high-power LED lighting market, the number of enterprises entering high-power LED lighting will increase and the competition will become increasingly fierce.
