Although the Beijing Olympic Games has been more than a year old, many people can still clearly remember the moment of the opening ceremony of the Olympic Games. Among them, the actors are wrapped around the lights, dancing in the dark, or expelling various formations, making people feel like they are also true and magical. People are full of praise and unforgettable. One of the heroes who created such a magical atmosphere is the LEDs in the lamp belt, which radiate brilliant light.
Since last year, LEDs have become popular, LED TVs have been new products, and they have been recognized by consumers. LED lighting has also been widely used in the commercial field. LED environmental protection and energy-saving features have begun to gain popularity. In ordinary households, there is very little use of LED lighting. At present, how much is the use of household LEDs? Can't buy it in the market? How much energy is there? The author conducted an interview on this.
In the recent Copenhagen conference, energy conservation and emission reduction has become an important issue that people pay attention to and pay attention to. Governments have reached a consensus on green energy conservation and environmental protection. The future of green energy conservation and energy conservation related industries is bright, LED TV has become Many people in the industry recognize the future development trend of TV, and the LED lighting industry is rapidly gaining momentum. Since last year, LEDs have become more and more popular, but only in their LED applications in commercial lighting, and the application of LEDs in the home field is still in its infancy.
Before New Year's Day, Chengdu and even the first specialty store specializing in LED lamps in the west opened. This Mingjia Lighting from Shenzhen is currently a professional manufacturer of LED lamps in China. According to Li Chun'an, the chairman of the company, with the global energy crisis and the worsening of the environment, energy conservation and environmental protection are imperative. The US Department of Energy predicts that by 2010, 55% of incandescent lamps and fluorescent lamps will be replaced by semiconductors, saving $35 billion annually. Japan, Europe and other countries around the world are banned from using incandescent bulbs, and LED lighting is the most A good alternative. LED has become the third human light source revolution after incandescent and fluorescent lamps. LED in the field of commercial lighting mainly concentrated in street lamps, tunnel lights, urban municipal lighting projects, billboards, office lighting, window lighting, etc., although the price of LED is expensive, but in the field of commercial lighting, it is more environmentally friendly, energy-saving, Light efficiency factors have been widely recognized and accepted in applications. At present, LED lights are mainly used in backlighting of mobile phones and computers, LED flat-panel TVs, and outdoor lighting such as landscapes and sign lights, and indoor home lighting has not yet been popularized.
Less energy-efficient "damage" than traditional luminaires
LED energy saving is an undisputed fact. In addition to energy saving, what are the advantages of LED lighting compared with traditional lamps? Li Chun'an told the author that in the past lighting fixtures, the basic lighting fixtures mainly used metal halide lamps, and the lamps themselves and the selected ballasts consumed too much power, the subsequent power expenses were high, and the instantaneous switching current was large. The cost of initial installation of wires is high. More importantly, the light spectrum of the lamp contains ultraviolet light, and the long-time illumination will damage the surface color of the object to be illuminated. For the merchant, some long-illuminated displays will become discounted goods, which will damage the interests of the merchant. In addition, the controllability of this kind of light line is not good, the effective light can not be controlled, the stray light is more, the dazzling glare, and the illuminating temperature is too high, for the merchants will also increase the indoor temperature, can not keep customers, increase Air conditioning fee. The quartz halogen lamp used for accent lighting has a good color rendering property, but has a problem of short service life and high power consumption, and converts 80% of electric power into infrared rays, thereby converting it into heat.
In addition to energy saving, LED lights do not have any heat generated by infrared rays, nor ultraviolet rays, and do not harm the objects being photographed. Moreover, the direction is very strong, and artificial lighting can strictly control the light. "Where is it bright, where is it?" Bright, so that the products being illuminated, especially diamond jewelry, produce stronger reflections, making the products more dazzling. “Therefore, almost all the gold stores and jewelry stores use LED lighting.†Li Chunan said, “Because the light emitted by the LED has almost no temperature, it can greatly reduce the room temperature of the store, reduce the cost of air conditioning, and create a good shopping environment. Moreover, the life of the LED is 20,000 to 30,000 hours, which also reduces the trouble and cost of maintenance."
LED home lighting traces difficult to find the author came to the water mill river, nine eye bridge several lighting city, almost walked through the lighting city, did not see which merchant specializes in selling LED lamps. When asked about LED lighting, the boss mostly shook his head. The author noticed that many homes have LED strips for sale. These colorful decorative strips are only used as decoration for home decoration and are not used for lighting. In the Glorious Lighting City of Jiuyan Bridge, the author finally found that there is a store selling LED spotlights. The boss told the author that at present, LED lamps are rarely used at home, because the price of LED lamps is too expensive, not to mention that energy-saving lamps are now more energy-efficient. Therefore, many consumers do not "catch" the LED lamps, and it is not worthwhile. However, some young people accept LED spotlights and use LED spotlights when decorating their homes. Apart from energy-saving reasons, the most important thing is that LED spotlights have long life, low maintenance costs and less trouble. He took out an LED spotlight and calculated the account to the author: this LED spotlight is 35 yuan, plus the bracket is about 8 yuan, a set of more than 40 yuan, if you use ordinary lights, then a set of almost 13 yuan, but Ordinary lights are basically bad every year, they have to be replaced, and the cost of 13 yuan is paid every year, and the LED spotlights can be used for at least 7 or 8 years, which saves money and saves worry.
"There are fewer LED lamps for household use, and a lamp is more than 100 yuan. The same incandescent lamp is only 5 yuan. Even if it saves electricity, how many years will it save this money?" Expressed doubts. For the more energy-efficient LED energy-saving lamps, many citizens said that there is no concept. Another owner of the lighting city told the author that LED lights are commercially available, but the general public is lacking in interest, and only occasionally young people ask.
The price of one hundred yuan LED bulbs, although the energy-saving effect is good, but the current too high price, it is really difficult for ordinary consumers to accept. The same power of energy-saving lamps is up to a dozen yuan, the traditional incandescent lamp a few yuan, several times or even more than ten times the price difference, is the biggest obstacle to consumers' acceptance of recognition. In addition, the recognition of LED lamps in terms of energy saving, environmental protection, and service life is still far from sufficient.
The high price hinders the LEDs from entering the people's homes. It is understood that since the price of most LED energy-saving lamps is more than ten times that of ordinary energy-saving lamps, ordinary consumers cannot accept it. At present, the cost of household LED lamps is very high. The price of household LED lamps exported to the United States is as high as about US$20, so the price is the biggest obstacle to the popularity of household LED lamps in China. Why is the price of LED home lamps high? According to reports, the high cost of LED bulbs mainly comes from three aspects: First, high-power LED light source, although a 0.05W LED light source costs only a few cents, but a 10W LED light source costs nearly 100 yuan; the second is LED Control chip, the current general solution requires three control chips to control one LED light source; third, in order to make the LED light bulb have good heat dissipation effect, the bulb outer shell needs to be made of high cost materials such as aluminum alloy. Due to the high cost of the core component of the LED lamp, the price of the terminal product is several times higher than that of the ordinary incandescent lamp and the energy-saving lamp. Take a LED table lamp as an example, the price is as high as eight or nine hundred, and the imported brand is sold for thousands of dollars, nearly ten times higher than the ordinary table lamp.
How to control its high production cost, this is a key to the popularity of LED home lighting, and this is mainly because China's current LED core technology research and development is still very weak, LED lighting manufacturers mostly lack independence Many R&D capabilities are based on simple packaging and extensive production. Naturally, the key technologies of LED core cannot be mastered, and the production cost cannot be reduced. In time, the breakthrough of LED core technology will inevitably bring down the cost in the production process. Therefore, the industry is optimistic about the home lighting application of LED lights. Some insiders believe that with the increasing research and development of the LED industry in the world, the technology will become more and more mature. In one to three years, the promotion of LED lighting will be greatly improved.
LED home does not save money?
As a new type of lighting products, LED lights have been accepted by a small number of consumers, but in the face of numerous LED lighting products, how do consumers choose the products that are most suitable for them? Experts said that LED lamps can be used for 35,000 to 50,000 hours under certain heat dissipation and use environments. Because there is no filament, they can withstand more shock than fluorescent lamps and incandescent lamps. The coverage color of white LED lamps is better than other white light sources. wide. Although such lamps have many advantages, some LEDs are less energy efficient than power saving bulbs unless they purchase regular advanced products. Therefore, consumers are advised not to buy blindly, depending on actual needs and effects. At present, LED lamp products on the market can be divided into three categories: high directivity, standard type and scattering type. Among them, the high-directional illuminator can be used as a local illumination source, the standard type is usually used as an indicator light, and the scattering type is an indicator light with a large angle of view, which can be used for illumination in a large area. Since the LED beam itself does not contain infrared rays or ultraviolet rays, it is most suitable for the occasion of protecting the object to be illuminated, such as for museums and shop exhibits.
