Recently, the National Semiconductor Lighting Engineering R&D and Industry Alliance Industry Research Institute (CSA) released the first quarter of the 2014 LED industry analysis report. The report shows that in the first quarter of 2014, the global semiconductor lighting industry has a strong growth momentum, and the LED technology level has reached a new high. Exports have maintained steady growth, domestic sales have gradually increased, and the domestic market is well-being. Business orders are full. From the overall data, although the price of LED products continued to decline, the rate of decline began to slow down; LED listed companies were generally optimistic in the first quarter, with an average profit increase of 27 or more. There are indications that in the first quarter of 2014, the LED lighting industry was not in the off-season.
LED lighting technology has broken through. This year's government work report has repeatedly mentioned energy conservation and emission reduction, promoted the transformation of energy production and consumption patterns, increased energy conservation and emission reduction, controlled total energy consumption, and reduced energy consumption intensity. CSA Research Institute analysts introduced, from March 1, 2014, the implementation of "LED stage lighting general technical conditions", "Import and export lighting equipment inspection procedures Part 2: LED modules for general lighting", further refined LED lighting products Relevant standards; on February 19, the Ministry of Science and Technology, Ministry of Industry and Information Technology organized the "Notice on Printing and Distributing the Special Action Plan for Energy Conservation and Emission Reduction in 2014-2015" to encourage clear industrialization prospects such as semiconductor lighting. The major energy-saving and emission-reduction technologies will further deepen the implementation of industrial demonstration projects such as the Ten City Wanhao Semiconductor Lighting Application Engineering, encourage enterprises to increase investment in research and development, and further expand market share through technological innovation.
In the first quarter, the LED lighting efficacy record was continuously refreshed. In March of this year, Cree's single white light high-power LED device broke through the 300 mark, and it was driven by 350MA at room temperature. With a color temperature of 5150K, the light efficiency reached 303 lm/w. This made the light effect competition upgrade again, which also triggered The debate on LED limit light efficiency.
CSA Research and Development Department analysts believe that high light efficiency and high light quality is not an all-or-one zero-sum game. It is the ultimate goal to improve light quality through effective combination of light efficiency and light quality.
In addition to light effects, the intelligent heat of LED lighting products has also increased. Many international manufacturers of LED lighting products are transforming into system service providers, and through the intelligent system integration of lighting systems, further improve lighting energy efficiency and save energy. Domestic companies have also entered the field of intelligent lighting, introducing LED lamps with dimmable colors. According to preliminary estimates by the CSA Research Institute, the demand for intelligent lighting products in China exceeds 10 million per year. In addition, there are 193 smart city pilots in China. In the future, combined with the construction of smart cities and the concept of smart home, the prospects for smart lighting can be period.
Of course, this season, creative products in the field of lED lighting are also on the scene. Among them, the Nanoleaf nano-LED bulb invested by Li Ka-shing and the Goccia smart button developed by Guocheng Wantong, a national key laboratory of semiconductor lighting innovation, are very eye-catching.
Strategic layout to activate production capacity to release listed companies has always been the focus of the industry. CSA's quarterly survey data shows that LED listed companies continue to maintain rapid growth since the second quarter of 2013. The continuous explosive growth of the downstream lighting market has driven the release of production capacity in the middle and upper reaches, and the industry's overall prosperity index has risen. The overall performance of the LED sector in the stock market is remarkable.
According to CSA technicians, the LED upstream chip industry is growing rapidly due to the strong demand from the downstream lighting market. CSA research shows that the current capacity utilization rate of China's LED upstream enterprises is about 70, and the capacity utilization rate of several leading enterprises such as Sanan Optoelectronics Co., Ltd., Silan Mingxin and Ganzhao Optoelectronics has reached 90 or above. .
In the midstream, with the continuous changes in market demand and the emergence of new packaging technologies such as gold-free packaging and EMC, the product structure of the package is constantly changing. Among them, COB products show good lighting effects in specific lighting fields, making the export market particularly popular for COB products, and all major midstream packaging manufacturers have increased their efforts to expand COB packaging products. Because the heat dissipation performance of the luminaire tends to be the decisive factor for light quality and lighting stability, COB will gain more advantages in the market competition due to its lower thermal resistance relative to SMD. According to CSA research data, the total share of COB in China's packaged products has exceeded 7, while in some enterprises this proportion is even higher, even more than 15.
Downstream, CSA judges that related companies are making efforts to expand channels. Some lighting manufacturers and channel vendors generally reflect that the first-quarter orders have improved greatly compared with the same period last year. Some dealers even reported that they have completed the whole year's orders in the first quarter. The overall growth rate of the manufacturers in 2014 is generally higher than 50. At the same time, in addition to the first- and second-tier markets, the third- and fourth-tier markets have also started to increase this year, and the competition for downstream channel resources has entered a feverish degree.
Overseas gold boosts domestic demand. In 2013, China's LED lighting products penetration rate was about 8.9. In 2014, as the second important time point for the ban on incandescent lamps, it will also bring a new wave of LED lighting market growth peak. CSA Research and Development Department analyzed that from 3 to 5 years from 2014, the LED lighting industry will usher in explosive growth and enter the gold for three years. With the opening of the home lighting market, the deep mining of the downstream application market will drive the sound development of the entire industry chain.
In the overseas market, in the first quarter of 2014, China's LED lighting exports continued to maintain rapid growth. The export volume of LED lamps increased by 143.2, the highest increase in history. The cumulative export of LED lamps was 1.905 billion US dollars. From the perspective of export destinations, the EU is still China's largest overseas market, and its export value accounts for 21.9% of the total. However, due to the EU's latest LED lighting product standards and energy efficiency standards, it further regulates and raises the import threshold for domestic Export products have a certain impact, and domestic LED manufacturers need to make targeted adjustments to export products. In addition, due to the US general ban on traditional low-energy products such as incandescent lamps in 2014, the US market maintained the growth rate of 63.09 as the second largest market, but the Japanese market share dropped from 14.46 to 7.89. It is worth noting that the BRICS The country's market share has expanded rapidly, with a year-on-year increase of 151.94 in the first quarter of 2014, accounting for 6.33.
In contrast to the domestic market, the demand situation is rising. According to CSA calculations, the annual lighting market brought by new buildings in China exceeds 1.1 trillion lumens, of which commercial lighting, office lighting and home lighting are the fastest segment of LED penetration. CSA conservatively estimates that at least 2 million LED lamps will be added in January-February 2014.
Although the LED lighting industry delivered satisfactory answers in the first quarter of 2014, CSA also reminded that at present, the prices of products in all aspects of the LED lighting industry industry chain continue to decline, reducing the overall gross profit margin of the industry, in addition, rising financing costs To a certain extent, it also causes the compression of corporate profit margins. Of course, for consumers, this means that the price difference between finished LED lamps and traditional products is further narrowed, and the price of LED lamps is close to the sweet spot that the mass market can accept.
