As a structural component of electronic products, heat sinks have a wide range of applications, including consumer electronics, servers, medical devices, power energy, transportation, LED lighting products, etc., all of which may involve the use of heat sinks. The market potential for electronic product heat sinks is enormous. 1. Market Prospect Analysis of LED Lighting and Cooling Component Industry
(1) The demand for LED lighting heat dissipation drives the development of the LED lighting heat dissipation industry
LED is a photoelectric device, in which only 10% to 40% of electrical energy is converted into light energy during its operation, while almost all the remaining electrical energy is converted into thermal energy. For LED lighting fixtures used for lighting, the required lumen amount may exceed thousands of lumens or tens of thousands of lumens in a specific area. The heat generated during the LED working process is concentrated in a very small chip, and the chip temperature increases, causing nonuniform distribution of thermal stress, a decrease in chip luminous efficiency, and fluorescence powder lasing efficiency; 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 more severe. Solving the heat dissipation problem has become a prerequisite for LED lighting, especially high-power LED lighting applications.
Optimizing the structural design of lighting fixtures 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 in the market are mainly composed of LED light sources, driving power supplies, heat sinks, and other structural components. The heat sinks and other structural components together constitute the heat dissipation components of LED lighting products. The heat dissipation component undertakes the heat dissipation function, and also serves as the lamp housing to protect electronic devices from dust, liquids, or unnecessary contact with other substances. A typical LED lamp structure is as follows:
In recent years, with the increasingly widespread application of LED lighting, the LED lighting industry has developed rapidly, and the division of labor in the industry has also made significant progress. LED lamp manufacturers with channel advantages purchase heat dissipation components, LED light sources, and driver power from suppliers, and then assemble them into finished lamps for sale to their downstream customers. The growth in demand from customers such as lamp manufacturers is driving the continuous development of the LED lighting and heat dissipation component industry.
(2) LED lighting industry market growth opens up growth space for the cooling component industry
Compared with traditional light sources such as incandescent lamps and fluorescent lamps, LED lighting has advantages in energy conservation, environmental protection, service life, color, volume, reaction time, and other aspects. 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 significantly decreased. Driven by the cost decline, the prices of LED lighting products have also shown a sharp downward trend in the past two years; On the other hand, governments around the world have also supported the LED lighting industry through a series of policy measures such as banning incandescent lamps, providing research and development subsidies, equipment subsidies, terminal subsidies, targeted procurement, and encouraging contract energy management models. Driven by these two factors, the global penetration rate of LED lighting has greatly improved.
While the global penetration rate of LED lighting has significantly increased, the global LED lighting market is also showing a rapid growth trend. According to data from Digitimes, a Taiwanese market research firm, the global LED lighting market size was 1.75 billion US dollars in 2009 and 3.717 billion US dollars in 2010, with a growth rate of 112%; In 2012, the market size exceeded the $10 billion mark, reaching $12.148 billion; In 2015, the global LED lighting market size was 29.908 billion US dollars, with a compound annual growth rate of 60.49% from 2009 to 2015.
It is estimated that the global LED lighting market size will reach 34.64 billion US dollars in 2016, an increase of 15.8% compared to 2015, and the global LED lighting market is growing rapidly.
At present, the LED lighting market in China has also entered a growth period. With the improvement of the cost-effectiveness of LED chips, the development of comprehensive lighting design, driver control, heat dissipation and other technologies, as well as the improvement and maturity of various LED lighting solution systems for different lighting environment application characteristics, LED lighting has increasingly penetrated into the traditional lighting field and gradually been widely applied and promoted. In 2014, China's domestic production of LED lighting products was about 1.67 billion units, with domestic sales of about 750 million units. The domestic market share of LED lighting products (domestic sales of LED lighting products/total domestic sales of lighting products) reached 16.4%, an increase of about 7 percentage points from 8.9% in 2013. Among them, commercial lighting showed explosive growth, public lighting grew rapidly, and home lighting began to start.
In 2015, the global acceleration of the elimination of incandescent lamps made LED the mainstream light source for lighting. In 2015, China's domestic production of LED lighting products was about 6 billion units, with domestic sales of about 2.8 billion units. The domestic market share of LED lighting products reached 32%, an increase of about 15 percentage points compared to 2014. In 2016, the domestic production of LED lighting products in China was about 8 billion units, a year-on-year increase of 33%; The domestic sales volume is about 3.8 billion units, a year-on-year increase of 35%. The domestic market share of LED lighting products has reached 42%, an increase of 10 percentage points compared to 2015.
