With the continuous growth of lighting in production, living, and urban streets, the role of lighting power in power consumption has become increasingly prominent. According to the statistics of China International Lighting Network, the proportion of lighting consumption in developed countries has accounted for 25%. In contrast, although China's economic development level is relatively low, lighting power consumption has accounted for more than 12% of the country's total electricity consumption, and is increasing at an average annual rate of 15%. According to authoritative experts, taking the domestic urban road lighting in 2007 as an example, if one-third of China's urban road lighting sources are replaced with energy-efficient lighting products, the electricity consumption saved is equivalent to the power generation of a Three Gorges project. Therefore, the National Development and Reform Commission has cooperated with the United Nations Development Programme (UNDP) and the Global Environment Facility (GEF) to jointly carry out the project of “China gradually phase out incandescent lamps and accelerate the promotion of energy-saving lampsâ€. As an alternative to incandescent lamps, the market for energy-efficient lighting products is welcoming good opportunities for rapid growth, especially as a revolutionary new light source. Under the general trend of “low carbon†and “energy savingâ€, LEDs are taking off. wing.
In the high-tech boom of low-carbon economy, all kinds of energy-saving lighting products have appeared on the market. However, behind this dazzling scene, the highly audible phosphor-type energy-saving lamps hide many unknown deadly threats. If you can't clearly understand the fatal flaws of phosphor-type energy-saving lamps and let them drive along with the new LED light source, then behind the prosperity of the energy-saving and emission-reduction market, it is foreseeable that China will bear disastrous consequences in the future.
In terms of many aspects, whether it is from the perspective of environmental protection or comparing technical indicators, phosphor-type energy-saving lamps should also be replaced by new LED light sources:
First, the pollution of raw materials and the inability to recycle: Everyone knows clearly that phosphor-type energy-saving lamps contain pollution killers - mercury, and one lamp contains an average of 0.5 mg of mercury. If it penetrates into the ground, it can cause 180 tons of water pollution. At present, there is no scientific way to recover energy-saving lamps to prevent pollution. The deep-buried practices generally adopted today are seriously polluting water sources. Nowadays, many countries are advocating “energy-saving lamps to replace incandescent lampsâ€, which is understandable from the perspective of energy conservation, but it is not feasible from the perspective of environmental protection. Compared with incandescent lamps and phosphor-type energy-saving lamps, although incandescent lamps have high energy consumption, but there is no mercury that can pollute the environment, phosphor-type energy-saving lamps save energy but contain pollution killers - mercury. We think that in the stage of developing a low-carbon economy and a green economy, taking China as an example, if 1.3 billion people use 5 energy-saving lamps per person per year, a total of 6.5 billion, it is equivalent to 3.25 million grams of mercury pollution. Infiltration into the ground will cause 117 billion tons of water pollution, and the consequences are unimaginable. Only this point, it should withdraw from the historical stage.
Second, the strobe is serious: the energy-saving lamp has a severe strobe, about 100-200 strobes per second. According to statistics, the increase in the proportion of students' nearsightedness is related to the fluorescent lamps in the classroom, and in some fine operation areas, the severe stroboscopic flashlights cause fatigue of employees, affect the fineness of operation, and have potential safety hazards.
Third, the light decay is serious: Although the energy-saving lamp manufacturers, especially the T5 pipe manufacturers have a life expectancy of 30,000 hours or so, almost all domestic T5 energy-saving application cases have experienced serious light decay in about half a year, seriously affecting the use. The lighting quality of the environment, and even some industries have to ban the use of T5 tubes. Moreover, the T5 tube replaces the T8 tube, and the overall investment is also large. The whole lamp needs to be replaced. As a result, the customer has to replace it in about half a year. The intention is to save energy and save money, but the result is a lot of money and time.
Compared with energy-saving lamps, LED lighting fixtures have demonstrated many unique advantages, more in line with the "low-carbon" and "energy-saving" concepts, and with the advancement of LED technology and application acceleration, will greatly promote the global "low carbon" and "Energy saving" process.
First, the environmental protection of raw materials: In the whole set of LED lamps, whether it is the lamp housing, radiator, power supply or light source part, it does not contain or add materials that pollute the environment, and the recovery is relatively easy.
Second, the light comfort is very strong: the light is comfortable, soft, no stroboscopic. Nowadays, LED lighting fixtures have been mostly used in surgical lighting for medical institutions with extremely high lighting requirements.
Third, super intelligent control: the speciality of LED light source, can use different light distribution methods in different applications, that is, to improve the efficiency of light use under the given power, energy saving is obvious; in addition, LED is low voltage power supply, the drive power can be adapted The wide voltage can be well combined with various intelligent control systems, including infrared sensing, clock control, and regional independent control. These revolutions in lighting sources enable people to enjoy modern smart living.
On April 28, 2009, the Ministry of Science and Technology officially issued Document No. 189, agreeing to carry out pilot projects for semiconductor lighting application engineering (referred to as “Ten Cities and Ten Thousand Milesâ€) in 21 cities including Shanghai, Chengdu, and Tianjin, and to use LED street lamps on a large scale. LED streetlights major technology demonstration project announced to the world that LED lighting from traditional landscape lighting to road lighting, and smoothly scaled to use. By the end of 2009, almost every province in China had demonstration application projects for LED road lighting. Indoor lighting applications are advancing by leaps and bounds. Metro, trains, large supermarkets, shopping malls, underground parking lots, office buildings, industrial enterprises, etc. are gradually beginning to use LED lighting products on a large scale. The US Department of Energy test data also shows that LED lamps can save about 22% more energy than today's most advanced fluorescent lamps, and preview the transformation of LED lamps from special lighting to general lighting. In response to this change, international lighting giants GE, Philips, Osram, Panasonic, GP, etc. have launched corresponding LED products. LED industry parks in many regions of China are also under construction. Some predators outside the industry are also involved in the LED field, such as: Haier, Midea, Jiuzhou; domestic industry giants are not willing to show weakness, have invested heavily in LED R & D and production, such as TCL , NVC, Shifu, Liaoyuan; and enterprises with deep roots for industrial upgrading, without traditional lighting constraints, lightly loaded, bold innovation, accumulated valuable experience for the progress of the industry, such as Sichuan Xinli light source, from high-efficiency phosphors Since then, it has entered the field of LED lighting, and has obtained more than 100 patents and more than 60 commercial lighting projects. Zhang Mingshi, chairman of Xinli Light Source, proposed to create LED lighting products that can be afforded by ordinary people in 2010.
With the continuous improvement of LED luminous efficiency and the continuous decline of the price of upstream product chips (in accordance with Moore's Law), coupled with other breakthroughs in LED lighting, LED lighting has begun to outperform fluorescent lighting in some aspects. Active in the lighting market. In addition, the effective guidance and support of the policy is also escorting the rapid and scientific development of LED. Yan Jun, deputy secretary general of the National Semiconductor Lighting Engineering R&D and Industry Alliance, said that in 2010, China will continue to promote LED lighting. In addition to the local government's subsidies for LED street lights, the National Development and Reform Commission also plans to look forward to the industry's long-awaited LEDs in the first half of 2010. Lighting is included in the scope of subsidies.
Undoubtedly, the concept of “low carbon†and “energy saving†is changing the way of life of human beings, and at the same time greatly promoting the adjustment of industrial structure, and will also promote the rapid development of some industries. LED lamps, as the representative of the advantages of people's production and life essential lighting products, will surely be able to take off in the global "low carbon" and "energy saving" main melody. As a competitive enterprise engaged in R&D and application of LED lighting products for many years, Xinli Light Source not only has to go all the way, but also should shoulder the historical mission entrusted by the times in the process of taking off the LED industry, and integrate all resources that can be integrated. Grasp the application and set the plan, and continue to dedicate momentum and set an example for the industry to take off.
