LED industry information
In 2014, it must be a period of restlessness. LED development has entered a special period. From many aspects, it can be seen that the LED era has developed into a special node: 1. “Dataâ€: It is not difficult to see from the industry data, some brands LED product sales have reached 30% of total sales, and even more. For example, sunlight, Buddha photos, etc. are all representative brands. 2. "Alternative": LED product performance price has completed the replacement of fluorescent products, this year is expected to complete the replacement of HID. LEDs gradually replace the original lamps, enabling LEDs to fully cover the market. 3. "Slipping": Sales of traditional light source products such as Philips have fallen sharply, and their proportion has gradually narrowed. It is not difficult to see from the above three points that LED lighting has ushered in the peak period of the upcoming transformation, so enterprises should be prepared to meet the arrival of the great era with the best attitude. There are more and more LED smart bulbs in the market. In this era of smart homes, one person decided to make a "unsmart" light bulb, a 5000K color temperature bulb, Blink Sunshine. He is Bloomberg. The 2700K "warm white light" on the market is too yellow, and the 6500K "white light" is too blue, and the color temperature can directly affect people's emotions. It is not necessarily a bad thing to do "unwise" lights in the era when smart homes are beginning to spread. On the one hand, when a big factory starts to make smart light bulbs, the space for entrepreneurs will be reduced. If you don't find new entry points, it will be difficult to survive, so this time is also correct. On the other hand, the current smart light bulbs are too dependent on mobile phones, and in many cases they only give users a greater burden and increase the chances of enslaving people with technology. Patent risk As Japan's white light patent protection period is approaching, Japan and Japan are frequently fighting patent wars in order to protect their interests. It can be seen that the patent war surrounding the white LED has not stopped, and even the final madness will be staged. How to establish effective patent infringement risk prevention measures is a difficult problem facing domestic packaging enterprises. One of the measures that may work in the short term is to rely on independent research and development to improve the technical level of China's phosphors, so that the comprehensive performance of local phosphors can reach or exceed those of foreign products. In particular, the peripheral key technologies such as the synthesis process, post-treatment technology and surface coating technology of phosphors are actively carried out. In fact, this is precisely the patent strategy adopted by Japanese companies when they entered the European and American markets. Therefore, it provides preparation for patent risk prevention and control of local packaging enterprises. The latest LED research report released by the 100 billion scale predicts that global LED lighting product shipments will increase by 68% in 2014 compared to 2013. Among them, the growth rate in North America is expected to reach 72%, and the growth rate of LED lighting products in the mainland China market is 86%. At the same time, with the support of policies, the progress of LED manufacturers in the mainland market will be significantly accelerated, and new situations may be opened in terms of industrial integration and technological progress. This means that under the multiple benefits, the global LED lighting market is expected to hit the 100 billion scale for the first time this year, which will also have an impact on the listed business of this year. As the chip is in the upstream of the LED industry, the performance of the crystal market will affect the development trend of the industry. Guojin Securities Research believes that LED is the most certain industry this year. From the perspective of the entire market, there is no need to worry about demand in the first half of the year, and there is no need to worry about supply in the second half High-brightness lighting From 2014 to 2017, the CAGR of high-power LED shipments for streetlights, direct-lit backlights, spotlights and other high-brightness applications is expected to reach 13%. It is predicted that the demand for high-power LEDs will increase from 18.5 billion in 2014 to 27 billion in 2017. In 2014, the application of high-power LEDs in streetlights will account for 28% of total high-power LED shipments, followed by TV backlights and spotlights, each accounting for 27%. However, it is predicted that by 2017, street lamps will dominate the high-power LED market with a market share of 41%, followed by spotlights (21%) and TV backlights (15%). In order to improve thermal conductivity, high power LEDs use ceramic substrates instead of the PPA materials originally used. At the same time, in order to avoid the influence of humidity on the LED, the silicone package was replaced by glass. In the use of high-power LEDs, the management of heat is very important because it affects the reliability of the product. With the rising cost of energy, high-brightness lighting demand will continue to grow in order to achieve energy efficiency. The "money" scene of the alliance lighting LED lighting industry has been more and more popular among the industry. Many industry practitioners actively robbed this "fat meat" and invested in the LED field, on the production line, building factories, opening stores, Building stores and so on. Figures show that the number of LED manufacturers in mainland China is increasing at a geometrically exaggerated speed. At the same time, however, the swarming LED cluster has spawned fierce competition, and non-healthy competition such as price wars and homogenization has broken out. In order to cope with fierce competition and establish a healthy competitive relationship between lips and teeth, many companies have embarked on the road of cooperation in alliances. What is even more surprising is that lighting stores, as direct service providers of lighting companies, are also actively seeking cooperation. All kinds of alliance teams are coming in and out, which also shows us that the lighting industry has gone through ignorance and began to enter the mature stage. The era of single-handedness is over, the future is the era of joint efforts, and the era of the major leagues has come. Keywords: Dark horse In the current lighting market, the development of LED lighting market is booming, which promotes the rapid development of lighting fixtures such as flat panel lights. LED panel lights are attracting attention in the global lighting market with the attitude of dark horse. In the next 10 years, the brightness of flat panel lights is expected to increase by 20 times, and the cost will be reduced to 1/10 of the existing one. Flat panel lamps have a higher luminous efficiency ratio. At work, LED electro-optic conversion efficiency is 30% to 50%, which is three to five times that of traditional incandescent lamps. That is to say, to achieve the same brightness effect, the panel lamp is more than 60% more energy efficient than the traditional incandescent lamp. In terms of brightness, LEDs and incandescent lamps have higher brightness when the energy consumption is the same. In addition, LED panel lights are also characterized by environmental protection, long life, high cost performance, convenient transportation and installation. With these advantages, flat panel lights have become the "main force" of urban landscape lighting, and will be more and more integrated into the people's Life and development prospects are great. In the 2.0 era, more and more customers have proposed to solve the problem of mixing different batches of lights or modules. After the display is installed in the field, it needs to match the previous display to the same gamut space. Space correction to standard color space such as SRGB/NTSC. These problems are collectively referred to as chromaticity correction. If the pure brightness correction technique is used as the 1.0 era of point-by-point correction, then the chromaticity correction technique will become the 2.0 era of point-by-point correction. Chroma correction will not only be limited to the basic problems of chromatic aberration and mosaic of LED display, but also raise the color reproduction degree of LED display to a higher level. Therefore, we have reason to believe that there is a point by point in the 2.0 era. The correction will usher in a broader development space.
