Expert analysis: LED lighting promotion application said easy to navigate (Photos)
The fascinating rise of LED (LightEmittingDiode) has become a typical symbol of high-tech progress in the late 20th century. It has been recognized as the hope of a new energy-saving new light source for green lighting in the 21st century. It will be the invention of incandescent lamp as a modern human civilization in 1879. Since the milestone, the lighting technology industry has once again become the source of the epoch-making revolution. Today, global politicians, technology elites, financial investors, news media and energy-saving environmentalists all talk about LED as a fashion. Almost all technology magazines will publish LED information in a certain space. In 2009, China's Ministry of Science and Technology announced plans for 10 cities and millions of LED lights, and soon received positive responses from all over the country, and quickly evolved into a craze for hundreds of thousands of LED lights in 21 cities. So what is the actual situation of LED promotion and application? The objective conclusion is that it is easy to do. It can be said that the task of LED promotion and application is extremely arduous, but its progress is unstoppable by anyone, and we are engaged in green lighting. People must continue to explore and work tirelessly. LED has made great progress in the research and development of the global scientific and business community, and its progress in recent years is shown in Figure 1, and the US Department of Energy also lists the progress and improvement of LEDs. The trend shown in 2.
Considering the social and economic benefits of road lighting is extremely impressive, people are so enamored that the promotion and application of LED street lamps is completely understandable and unobjectionable. Many new products and application practices of LED street lamps have emerged in Figure 3 and Figure 4. Shown. However, due to the harsh and harsh external conditions of outdoor road lighting, coupled with the strict standards and special requirements of functional road lighting, there are many problems that LED road lighting can not ignore in the past, and the objective situation of application cannot be promoted on a large scale.
In response to the pressure of global LED mass production, the urgency of its promotion and application is urgent, and people of insight at home and abroad wisely shift the target to the application field of indoor lighting. As many countries in the world, including China, have now proposed that the world's nearly 10 billion incandescent lamps will exit the historical stage of lighting applications, this will provide a good opportunity for energy-saving LED bulbs, and the indoor application environment. It is more stable and suitable, which can reliably ensure the low light decay of the LED bulb and a long enough service life.
Taking Japan as an example, the current life of LEDs in the Japanese market is about 40,000 hours, which is 40 times that of incandescent lamps, 6 times that of compact energy-saving fluorescent lamps, and the power consumption is only 8 points of incandescent lamps. First, less than two-thirds of the compact energy-saving fluorescent lamps, the energy-saving effect is very significant. Only the price of a single lamp still costs about 300 yuan. Due to the continuous improvement of the performance of LED incandescent lamps and the continuous decline in prices, it is of course favored by foreign consumers. At the beginning of 2010, many large-scale electrical stores in the world have appeared out of stock. LED bulb manufacturers also have too many orders, production capacity. I can't keep up with the market demand. The LED bulb boom has not only prompted light source companies to increase production and development efforts, but also attracted many motor manufacturers to enter this field. For example, Toshiba Corporation of Japan announced in September 2009 that it will further strengthen its LED bulb business, and plans to invest 100 billion yen in equipment investment, and has set a sales increase from the current 20 billion yen to 350 billion yen by 2015. And increase the export volume by more than 30%, and in the near future will introduce new LED products that can adjust the brightness and the highest brightness in the world. Japan's Matsushita Co., Ltd. also decided to enter the home LED lighting market in September 2009. In October of the same year, it has launched 10 "EVERLEDS" series of LED bulbs. These new products cost only 19 yuan per lamp per year, which is better than incandescent lamps. With a price of 135 yuan less, the retail price of each lamp is about 350 yuan, and its new small LED bulb new product is about to come out. In addition, Sharp, Mitsubishi Electric and NEC and other large motor companies have also entered the LED bulb market, because they see the global efforts to promote environmentally friendly energy-saving products, the production of incandescent lamps is only a matter of time, so today's international Philips Companies, OSRAM and GE, the world's leading manufacturers of light source production, do not hesitate to participate in and strengthen the LED bulb business, mainly because they agree that the current breakthrough in LED application is indoor lighting, so China's LED industry We should also look forward to this direction and resolve to invest and participate in competition, so that China's LED lighting industry will make great strides in the direction of health and sustainability!
