My son asked me to take a good look at this LED light, come and come, and I will calculate this account together. In the lighting market, the uncle Li, who bought the lamps for his son’s wedding room, took the reporter and calculated it with paper and pencil. The incandescent lamp will definitely not be used. It is not energy-saving and environmentally friendly, and it is cheaper. It is said that this LED lamp is one time more powerful than the energy-saving lamp. The 7W LED lamp and the 15W energy-saving lamp are almost bright. If the average one-day use is 4 hours, the first-class saving will save 12 degrees (kWh). 1 degree electric five hair, can save 6 dollars in one year. However, the 7W LED lamp produced by a large manufacturer with a slightly better brand has no more than 70 yuan, which is 50 yuan more expensive than the 15W energy-saving lamp.
It took 10 years to save the money back! Uncle Li sighed and put down the LED lights in his hand. Although the LED lamp's energy-saving and environmentally-friendly long life is well known, but the high price still makes most consumers discouraged.
Consumers save energy and save money Most domestic companies can only import expensive foreign chips, so the price of LED lamps on the market is not difficult to understand.
Because of the obvious advantages of energy saving and long service life, LED lighting is rapidly spreading in commercial and public areas such as shopping malls, factories, and urban public facilities. However, for ordinary people, the average daily use time of home lighting is far less than that of commercial and public sectors. The long life span of more than ten years is not very attractive to consumers. Consumers are not saving money, and manufacturers and businesses are not selling well. This is the current dilemma of LED home lighting.
Why is the price of LED lamps high? From the LED industry chain, the most important factor affecting the price of LED terminal products is the price of LED chips, which is the market price of upstream products in the industry chain. Xiang Wei, manager of the industry promotion department of Shanghai Yaming Company, said in an interview with China Electronics News that the current LED chip technology is monopolized by a few international giants, even though China introduced a large number of chip packaging industries in the middle of the industry chain in the past few years, but Reducing the price of LED light sources is also difficult to play a direct role, and the price trend is still in the hands of a few famous chip manufacturers.
The upstream enterprises account for 70% of the profits of the industrial chain, and the middle and lower reaches together account for the remaining 30 profits. Qiu Huanguo, senior manager of Qinshang Optoelectronics International Business Department, said that LED chips are the core materials of LED lighting. At present, most of the LED lighting products in mainland China are mainly imported from the United States, Japan, Taiwan and other places. Converging in the middle and lower reaches of the packaging and application areas, most of the profits of mainland China LEDs remain in the upstream production location.
It is understood that most of the domestic LED enterprises are in the middle and lower reaches of the industrial chain, there are only a few in the upstream industrial chain, and the production is extremely difficult, the technical content is not enough, leading to the lack of core competitiveness of the LED industry. Taking Shenzhen as an example, the city currently has about 1,500 LED companies, accounting for 35 of the country, but most of them are in the field of packaging and application. There are no semiconductor materials or phosphors that are vital to the production of the products. .
Not only that, more than half of the technology and patents in the global LED field are occupied by a few large companies in developed countries such as the United States, Japan and Germany. Japan's Nichia, Japan's Toyota Synthetic, American Cree, Europe's Philips, Europe's Osram and others have applied for a number of patents to maintain their competitive edge and maintain their market share, covering almost the entire industry including raw materials, equipment, packaging and applications. chain.
Although many companies have begun to invest heavily in research and development, the number of domestic companies with core technology and patents for LED chips is less than 10, and the remaining 90 companies have to rely on the technology of foreign companies. Because most domestic companies can only import expensive chips, the price of LED lamps on the market is not difficult to understand.
Within 5 years, it will be popularized. If the chip is localized, the cost of LED lamps can be reduced to 30-40.
On July 11, the Ministry of Science and Technology issued the "Twelfth Five-Year Plan for the Development of Semiconductor Lighting Technology", clearly stating that semiconductor lighting products will achieve localization of more than 80 chips during the 12th Five-Year Plan period, and the cost will be reduced to 20 in 2011.
According to the current LED chip accounting for nearly 60% of the cost of lamps, if the chip is localized, only the price reduction of the chip can drive the cost of the lamp to drop by nearly 50. With the improvement of packaging technology and the popularization of high-efficiency and low-cost driving circuits, the cost of lamps can be reduced to the present. 30 to 40. By then, the price of LED lamps will be similar to that of energy-saving lamps.
According to the roadmap for the elimination of incandescent lamps released by the state last year, from October 1 this year, sales and import of incandescent lamps for general lighting of 100 watts and above will be banned. By October 1, 2016, sales and import of 15 watts will be banned. The above general lighting incandescent lamps. In the case of LED and energy-saving lamps, if the price is equal, the LED will take advantage. The benefits of energy saving, longevity, appearance, recycling, etc. are not mentioned. Instead of using high-impact mercury like energy-saving lamps, there is no public hazard such as leakage of mercury ions and phosphors that may be caused by broken bulbs. Safety and environmental protection LED lamps will become the first choice for home lighting.
The US Department of Energy report shows that the general lighting market will occupy 36 in 2020 and reach 75 in 2030. LED light efficiency will increase from the current 64.3lm/W to 147.3lm/W in 2020 and 176.3lm/W in 2030. Prices will fall from the current $169.49/thousand lumens to $5.03/thousand lumens in 2030.
At the beginning of last year, 28 production enterprises organized by the National Development and Reform Commission, the Ministry of Housing and Urban-Rural Development, and the Ministry of Transport signed an agreement to participate in demonstration projects of 50 LED products organized by local governments in 2011. Recently, the State Council researched and determined the policy measures to promote the consumption of energy-efficient home appliances and other products, and decided to arrange a financial subsidy of 2.2 billion yuan to support the promotion of energy-saving lighting including LED. With the introduction of a series of power policies, it is believed that the popularity of LED lamps during the 12th Five-Year Plan will become inevitable.
National standards have not yet developed a cheap and low-quality product, which will bring security risks and economic losses.
In daily life, the influence of optical radiation on human health cannot be ignored, or even an important cause of cataract, skin cancer, amblyopia, macular degeneration and pathological changes.
With the application of LED in general lighting and other consumer products, the harm of high-intensity LED blue light to the retina of human eyes has increasingly attracted international attention. The photobioradiation safety of LED is one of the priorities of the International Organization for Standardization and belongs to the category of international safety standards. However, due to the fact that the national standards for domestic LED products have not yet been formulated, companies are fighting each other. In order to reduce costs and gain advantages in price wars, individual companies use inferior raw materials, which not only reduces light efficiency and service life, but also It may cause harm to our eyes.
Compared with a year ago, the price of LED lamps has dropped sharply, and the products of more than one hundred yuan have dropped to about 70 yuan. Many consumers have decided to purchase them. When purchasing, you must not choose low-quality products because of cheap money, and bring unnecessary security risks and economic losses.
Expert suggestion: When purchasing LED lamps, first of all, you should purchase lamps with three guarantees and CCC certification mark. Secondly, it depends on whether the LED lamp product identification is complete, and the regular product should have the logo; again, it depends on the LED lamp power supply. Whether the line has the CCC safety certification mark; finally, it is also necessary to confirm whether the charged body of the lamp is exposed. After the light source is installed in the lamp holder, the finger should not touch the charged metal lamp head.
