China is one of the countries with relatively scarce forest resources in the world. The forest area is 158.941 million hectares, ranking fifth in the world, while the per capita forest area is only 0.128 hectares, equivalent to 21.3% of the world's per capita possession of 0.6 hectares. 112.66 billion cubic meters, ranking seventh in the world, the per capita forest stock is only 9.044 cubic meters, accounting for 15% of the world's per capita forest reserves of 60.6 cubic meters, and the forest coverage rate is 16.55%, which is only equivalent to the world average forest coverage. 27% of 61.3%. In order to protect the increasingly fragile ecological environment, the state initiated the natural forest protection project in 1998, which completely banned the cutting down of the natural forests in the upper and middle reaches of the Yangtze River and the Yellow River. The nationally planned timber was reduced from 67.102 million cubic meters in 1996 to 2000. The total area of ​​4,427,900 cubic meters is reduced by 3.972 million cubic meters per year. The reduction and control of wood harvesting has intensified the contradiction between timber supply and demand. China's per capita wood consumption is 0.22 cubic meters, which is only equivalent to 40.7% of the world's per capita wood consumption of 0.54 cubic meters. The supply of wood is far from meeting the needs of national economic construction and people's lives. According to statistics from relevant departments, the annual wood gap in China will reach 50 million cubic meters to 70 million cubic meters. By 2015, China's domestic timber supply and demand gap will reach 140 million - 150 million cubic meters. Therefore, in China, the production and consumption of wood substitutes should be developed in the direction of material-saving and environmental protection, and the comprehensive utilization rate of wood can be effectively alleviated to effectively alleviate the contradiction between supply and demand of timber in China. However, the emergence of science and technology can greatly improve the lack of domestic timber resources. The science and technology wood is made of ordinary wood (fast-growing material), using bionics principle, through various modified physical and chemical treatment of ordinary wood and fast-growing materials. A new all-wood decorative material with superior performance. Compared with natural materials, it hardly bends, cracks or twists. The density can be artificially controlled, and the product stability is good. In the process of processing, it does not have the waste and value loss in the processing of natural wood, and the comprehensive utilization rate of wood can be increased to more than 85%. Science and technology wood has the following characteristics: 1, rich colors, diverse textures The technology wood products are designed by computer to produce colors and textures that are not available in natural wood. The color is brighter, the texture is more solid, and the pattern is more dynamic and dynamic. Fully meet the diversified choices of people's needs and the realization of personalized consumer psychology. 2, the product performance is superior The physical properties such as the density and static bending strength of the science and technology wood are superior to the natural wood of the raw material, and it is easy to process, anti-corrosion, anti-mite, moisture-proof and easy to process. At the same time, it can be processed into different web sizes according to different needs, overcoming the limitations of natural wood-level. 3, high utilization rate of finished products, more savings in decoration Science and technology wood has no natural defects inherent in natural wood such as wormholes, thrift, and discoloration. It is a decorative material with almost no defects. At the same time, its texture and color have certain regularity, so it is very good in the decoration process. It avoids the troubles of natural wood products that are difficult to be spliced ​​due to differences in texture and color, allowing consumers to make full use of every inch of material purchased. 4. Guide the new trend of “green consumptionâ€, which is a true green product. Due to the broad application prospects of science and technology, the extension of the industrial chain in wood deep processing, and the potential function of improving the comprehensive utilization rate of wood, the science and technology development project was included in the Jiangsu Torch Program in 2002; it was also included in the national level in the same year. The torch project, the birth of science and technology wood products, is an excellent substitute for the increasingly scarce natural forest resources. It not only satisfies people's demand for decorative effects and dosage of different tree species, but also allows precious forest resources to continue. At the same time, E1 environmentally friendly rubber is used in the production process of science and technology wood. Five major categories of products (plywood, veneer, solid wood composite flooring, technical wood sawn timber, and scientific wood chipping) all meet the requirements of GB18580-2001, and all of them have obtained "China Environmental Labeling Products".

The development of science and technology wood helps to reduce the impact of wood resources
LED lamp is a light emitting diode (LED) as the light source of the lamp, with high efficiency, energy saving, environmental protection, long life and so on. LED table lamp uses LED as light source, soft light, no glare, suitable for long-term reading and work. Compared with ordinary desk lamps, LED desk lamps have higher energy efficiency, power consumption is only 20% to 30% of ordinary desk lamps, and the service life is far longer than ordinary desk lamps, up to 50,000 hours under normal use.
The advantages of LED table lamps include high efficiency and energy saving, environmental protection, long life, no strobe, and high color rendering index. It uses blue light isolation technology, which can effectively prevent myopia and protect eye health. In addition, the LED table lamp also has a multi-level dimming function, which can adjust the brightness according to different environments and needs, and improve the comfort of use .
When purchasing LED table lamps, it is recommended to choose products with soft light and high color rendering index according to the use scenario to protect eye health. At the same time, pay attention to the selection of well-known brands and products through national certification to ensure safety and quality. In addition, you can also pay attention to the dimming function, material and design of the lamp to ensure that it is coordinated with the home style and increase the beauty .
