Analysis of factors affecting the development of quartz tube industry
Incandescent lamps will be phased out, the wide use and substitution of medium and high-end light sources. Currently, the incandescent lamps commonly used in families belong to the first generation of thermal radiation light sources.
1. Favorable factors
(1) The market demand for quartz tubes has risen steadily
① Incandescent lamps will be phased out, the wide use and substitution of medium and high-end light sources. Currently, the incandescent lamps commonly used in families belong to the first generation of thermal radiation light sources. Although they have the advantages of low manufacturing cost and convenient use, their luminous efficiency is too low. Generally, only about 10% of the electric energy can be used for lighting, and the rest of the electric energy is converted into heat energy, which consumes too much energy, including energy-saving halogen lamps New lighting products such as low-power metal halide lamps can significantly improve energy efficiency and have a longer service life than ordinary incandescent lamps. Therefore, in order to reduce energy expenditure, save energy and reduce emissions, most countries and regions in the world have formulated corresponding plans to phase out the use of incandescent lamps in the near future. With the implementation of the above-mentioned incandescent lamp phase-out plan, quartz electric light source products such as energy-saving halogen lamps, low-power metal halide lamps and other energy-saving electric light source products will gradually replace incandescent lamps as basic electric light sources, As one of the main bubble shell materials of quartz electric light source products, the demand of quartz tube is expected to maintain a steady growth in the next few years.
② The industrial layout of quartz products is gradually transferred to China
First of all, due to the continuous development of relevant technologies in China's quartz tube industry and the cost advantage of domestic production and manufacturing, domestic quartz tubes are gradually replacing the products of foreign manufacturers with low cost performance. Secondly, China has become the world's largest lighting source producer and the manufacturing center of the world's light sources. The world's three largest lighting companies, Osram, Philips Lighting and GE Lighting, have transferred their production and procurement centers to China. This product substitution and the transfer of production centers will further improve the cost advantage and market competitiveness of China's quartz tube manufacturers, and the demand for quartz tubes for lighting in China will continue to rise steadily.
(2) The downstream photovoltaic industry of high-purity quartz sand has broad prospects
At present, the use of photovoltaic energy in the world's total energy consumption is extremely limited. According to the prediction of the World Energy Organization, the European Joint Research Center and the European Photovoltaic Industry Association, the world's photovoltaic power generation will account for 1% of the total electricity in 2020, and by 2040, photovoltaic power generation will account for 20% of the global power generation, and occupy an important position in the world's energy composition. According to this calculation, the annual composite growth rate of the global solar photovoltaic industry will be as high as 25% - 30% in the coming decades. Therefore, the global photovoltaic industry has a bright future and will continue to maintain stable growth. According to this calculation, high-purity quartz sand, as a supporting material for the photovoltaic industry, will also have broad market prospects in the future.
2. Adverse factors
The technological progress of new light source products (LED) may have an impact on the company's electro-optical source product market. In recent years, LED lighting products, known as the fourth generation electric light source products, have been strongly supported by government policies of various countries due to their good energy conservation, environmental protection and other characteristics. At present, the market scale in the application fields of low-power lighting, traffic signal light source, liquid crystal display light source, etc. is expanding continuously, and is expected to maintain rapid growth. In the long run, LED will gradually replace the traditional electric light source products. According to analysis, white LED will gradually replace the original electric light source products in the future in areas where the requirements for light source power and light intensity are not high. Therefore, LED will have a certain impact on other electric light source products in the future. However, in the process of replacing traditional electric light sources with LED lamps in the above fields, we need to overcome the double bottlenecks of technology and cost, which will take a long time. In addition, in some areas where high-power and strong light sources are needed, due to the lack of a good solution for LED luminous efficiency and consistency, high-power LED lamps cannot compete with energy-saving halogen lamps, HID lamps and other products in terms of cost performance. Therefore, from the perspective of the foreseeable future, the development of LED light sources will not have a significant adverse impact on quartz light source products, especially high-power light source products.
