LED lights to show the advantages of long-term lack of core patents rather prosperous new home marke  [2015-3-13]

Although the energy saving advantages are obvious, but large-scale alternative to traditional lighting LED lights take time.

Starting this year, the US market's best-selling 40-watt and 60-watt incandescent stop selling. In Asia, South Korea, Thailand, the Philippines have also taken measures to promote the use of energy-saving light bulbs instead of incandescent bulbs. From October 1 this year, our country will also ban the import and sale of 60 watts and above ordinary incandescent lighting. With the tide of global LED light source to replace pour, LED lighting market, "light" up. It is in good policy and good market prospects, driven in recent years, many domestic enterprises have set foot LED lighting lighting.

Behind the industrial prosperity, LED lighting product quality is good and bad. Reporters visited the market learned lamps on the market a 3 watt LED bulb lowest ever present two yuan, three yuan, there is a high range 50-60 yuan. The same parameters of different brands of the same product prices will not be starker. Many consumers may feel confused: This is to buy or not to buy? How should I choose? Although the LED lamps are energy-saving and environmental protection, and other advantages, but for now, really into millions of households still remains to be seen.

LED lights to show the advantages of long-term

General lighting incandescent and halogen lamps, although cheap, but the low light efficiency, short life, maintenance workload. Household saving lamps LED What are the advantages? "The same power consumption, the total amount of luminous LED lamps is 10 times incandescent, fluorescent 1.5 times. With the continuous improvement of technology, LED luminous efficiency there is still much room for growth. LED lamp life is fluorescent lamp 10 times, 100 times the incandescent lamp, and almost no maintenance. "experts said.

Reporters learned that, buy a LED light, equivalent to the purchase of 16 incandescent, buy an energy-saving lamps, then spent nine incandescent equivalent price. Just from the price point of view, buy LED lights clearly not as cost-effective energy-saving lamps and incandescent lamps. But count factors such as power consumption and lamp life, the LED lighting life of 15,000 hours, equivalent to 15 incandescent or energy-saving lamps and three. On consumption, incandescent need to consume 600 kWh, energy-saving lamps to 115.5 degrees, while LED lights only 69 degrees.

In addition to energy saving long outside, LED energy saving lamp household biggest advantage is environmentally friendly. Ordinary energy-saving lamps made of glass, a light bulb contains about 3-5 mg of mercury, once broken can contaminate about 1,000 tons of water and 300 cubic meter of air, and LED lights for the whole solid light, impact resistance not broken, conducive to recovery and no light pollution and radiation, and no UV radiation.

In addition, LED is completely encapsulated in epoxy, it is stronger than light bulbs and fluorescent tubes. Light body and no loose parts, these features make the LED bulb easily damaged. LED lights do not exist and stroboscopic effect, eliminating the traditional strobe light vision caused by decreased visual fatigue and other hazards.

Universal long way to go home

LED lights though obvious advantages, but are not yet into the civilian and home markets. New homes being renovated Zhang Jing told reporters that the family 12 large and small energy-saving lamps, with more than half of the ordinary energy-saving light bulbs, costing a total of about 130 yuan. "I do not know the home energy-saving LED lights, always thought that only large screen LED lights will be used." Recently, this reporter saw at the IKEA store Baoshan, a 7-watt energy-saving fluorescent light bulbs priced at 5.9 yuan Many consumers have won several passing only.

However, the only reason to enter the civilian market, the market is not high profile does not impede LED lights. It is understood that the price of household energy-saving lamps LED energy saving lamp three times higher than normal, up to 50,000 hours of useful life are not guaranteed, many consumers are still more inclined to ordinary energy-saving lamps.

Insiders pointed out that, LED lighting into ordinary families should be the trend, but will take time. Why LED lamps prices high? As Shanghai's first three new board listed in LED lighting business, Shanghai Science and Technology Co., Ltd., Li Jiansheng CDH that the core patent is caused by lack of the main reason for the high cost of LED lights. According to statistics, the current domestic LED substantial growth in the number of patent applications, though, even more than the United States the world's second column, but the lack of core patents as a constraint to the development of semiconductor lighting industry, a major bottleneck.

According to reports, if you want a normal LED bulbs prolonged use, a 1W material costs Need more than 9 million, three-watt bulb material cost not less than 20 yuan. But in order to enter the civilian market, many companies began to price war, many large companies are forced to lower prices, which is superior to its competitors in terms of price behavior at the expense of quality, the LED lighting products can not win the trust. Moreover, the average user is difficult to distinguish the product quality, professional equipment required for testing, testing found that some low-end products are glare, glare.

Reporters learned that the home market brand LED energy-saving lamps prices generally around 60 yuan each, there are some uneven product prices, so many consumers confused and disoriented, prohibitive. Insiders said that the current price of LED elements are still relatively high, this popularity and acceptance of LED lighting market in the whole impact.

This year the industry will accelerate reshuffle

Industry insiders estimate that, LED lighting market from the early follow, blind expansion, are now beginning to show up to practice, bow development, LED industry will usher in a major reshuffle.

"A few years ago we rush to engage in LED, especially for non-professionals expect some LED's are too high, resulting in different LED everyone to understand, resulting in their different quality positioning. Really have LED lighting design and R & D capabilities in the industry one of the few companies, many of which are profit-based manufacturers, will inevitably lead to the entire market was mixed. "Li Jiansheng, frankly, they have made a detour.

Back in 2000, CDH technology LED display products are mainly sold to manufacturers, wound up the market started to germinate. Although the market demand, but the vast majority of "skirmish" type companies generally do not scale, lack of continuity of production, making the line near CDH technology inadequate risk estimates bad debts are commonplace, companies repeatedly into a funding crisis. In 2004, the CDH technology specializing in LED lighting industry began aggressively. In 2006, the company applied to the Ministry of Science 863 LED packaging project, after which the product has been chosen in 2008 Beijing Olympic Games. Now, in the Shanghai Temple, Theme Pavilion, Yan'an Elevated Road, Nanpu Bridge and ten bridges along Suzhou Creek and other landmarks, have adopted CDH LED lighting products.

Although word of mouth to do it, but CDH Technology found that, because the company does not have the advantage of downstream channels lamps, profitability is not obvious. To this end, CDH technology focused research and development, production and sales resources, to play the advantages of the industrial chain in the middle of the package, the transition to LED supplier, specializing in the field of LED package, in terms of quality of products and technology efforts, and the creation of its own brand tripod Hui cards. In fact, bearing on the middle reaches of the epitaxial chip package, then under lighting applications, LED industry chain as a whole, the most important aspect of survival, quality of product packaging companies play an important impact on the entire industry. Currently, midstream packaging accounted for about 25% -30% of the whole industry chain. Li Jiansheng said CDH focuses on the development of science and technology-based integrated COB LED light source module light source technology has been successfully staged the mass production early this year. Using this technology, LED light source, can be used with a variety of shapes lamps. Currently, there are 60% -80% of companies have chosen to transition to COB packaging technology, which has become a new trend in the domestic LED lighting.

"The next 3-5 years, LED lighting products will gradually standardization, become conventional products. And this time it will usher in a major reshuffle LED industry. By then, there are brands, technology, capital strength of enterprises will will be based, and some low-end, brand-name companies can only survive in the slits. "Li Jiansheng think, when the LED lighting industry a positive interaction, LED lighting products in order to decrease costs as technology improved, the price will end consumer market less people can afford, affordable.

A short walk to pick the ideal LED lamps

Exist currently on the market with a lot of quality LED lamps, however hard, for how to buy the perfect LED lighting, has become a problem of many consumers. How can I buy into the desired LED lamps?

First, we must consider the "simple" products for the principle. Lighting in the room should play a finishing touch. Overly complex shape, too complicated colors are not suitable for simple design room.

Second, to facilitate the purchase of pre-installed LED lamps, most people have experienced the embarrassment of replacement bulbs Ceiling: stepping on the table, marching chair, head 90 degrees, lift the arms too far to 2.5 meters or even higher ceiling . Be sure to consider when choosing fixtures easy lamp replacement.

Moreover, LED energy saving both energy-saving lamps, lighting, sound, do not emit heat for long lamps. It should be noted that the energy-saving light bulbs are mostly standard screw, but there are two caliber chandelier, one is the standard, you can use the energy-saving light bulbs; one is non-standard, you can not use energy-saving light bulbs.
