Behind the industrial boom, the quality of LED lighting products is mixed. The reporter visited the lighting market and learned that at present, a 3-watt LED bulb has a minimum of 2 yuan and 3 yuan, and a high one has 50 yuan to 60 yuan. And the price of different brands with the same parameters of the same product will be very different. Many consumers are confused: Is this a buy or not? How to choose? Although LED lights have many advantages such as energy saving and environmental protection, at present, it will take time to really enter thousands of households.
The advantages of LED lights have long appeared
Incandescent lamps and tungsten halogen lamps for general lighting are inexpensive, but have low luminous efficiency, short life, and large maintenance workload. What are the advantages of LED household energy-saving lamps? "The same power consumption, the total amount of LED lamps is 10 times that of incandescent lamps, 1.5 times that of fluorescent lamps. With the continuous improvement of technology, LED luminous efficiency has greatly increased. Space LED lighting life is 10 times that of fluorescent lamps, 100 times that of incandescent lamps, and almost no maintenance." Experts said.
The reporter learned that buying an LED light is equivalent to purchasing 16 incandescent lamps. Buying an energy-saving lamp is equivalent to spending the price of nine incandescent lamps. From the price point of view, buying LED lights is obviously not as cost-effective as energy-saving lamps and incandescent lamps. But taking into account factors such as power consumption and lamp life, the LED lamp lighting life is 15,000 hours, which is equivalent to the sum of 15 incandescent lamps or 3 energy-saving lamps. In terms of power consumption, incandescent lamps need to consume 600 kWh, energy-saving lamps are 115.5 degrees, and LED lamps are only 69 degrees.
In addition to long-term energy saving, the biggest advantage of LED household energy-saving lamps is environmental protection. Ordinary energy-saving lamps are made of glass. One bulb contains about 3-5 milligrams of mercury. Once broken, it can pollute about 1,000 tons of water and 300 cubic meters of air. The LED lamp is an all-solid-state illuminator, which is resistant to impact and is not easy to be broken. Does not produce light pollution and heat radiation, nor ultraviolet radiation.
In addition, the LED is completely encapsulated in epoxy resin, which is stronger than bulbs and fluorescent tubes. There are also no loose parts in the lamp body, which make the LED bulb not easy to damage. Moreover, the LED lamp does not have a stroboscopic effect, which eliminates the harm of vision loss and visual fatigue caused by the stroboscopic light of the conventional light source.
Household popularity is a long way to go
Although LED lights have obvious advantages, they have not fully entered the civilian and household markets. Zhang Jing, who is working on the renovation of the new house, told the reporter that there are 12 energy-saving lamps in large and small homes, and more than half of them use ordinary energy-saving light bulbs, costing about 130 yuan. "I don't know that there are LED home energy-saving lamps. I always thought that LED lights would only be used on large screens." The reporter recently saw at the IKEA Baoshan store that a 7-watt fluorescent energy-saving light bulb is priced at 5.9 yuan. Many consumers have taken several passes.
However, the low market visibility is not the only reason that hinders the entry of LED lights into the civilian market. It is understood that the price of LED household energy-saving lamps is three times higher than ordinary energy-saving lamps, and the service life of up to 50,000 hours cannot be guaranteed. Many consumers are still more inclined to ordinary energy-saving lamps.
Insiders pointed out that LED lighting into the ordinary family should be the general trend, but it will take time. Why is the price of LED lamps high? As the first LED lighting company listed on the New Third Board in Shanghai, Li Jiansheng, chairman of Shanghai Dinghui Technology Co., Ltd. believes that the lack of core patents is the main reason for the high cost of LED lamps. According to relevant information, although the number of domestic LED patent applications has increased significantly, even surpassing the United States ranks second in the world, the lack of core patents has become a major bottleneck restricting the development of the semiconductor lighting industry.
According to reports, if an LED bulb wants to be used normally for a long time, the cost of a 1W material needs to be more than 9 yuan, and the cost of a 3 watt bulb material is not less than 20 yuan. However, in order to break into the civilian market, many companies have begun to fight price wars. Many large companies have also been forced to drive down prices. This kind of behavior that sacrifices quality in order to outperform competitors in price makes LED lighting products unable to win trust. Moreover, it is difficult for general users to distinguish the quality of products, and professional instruments are needed for testing. Some low-end products have glare and glare.
The reporter learned that the price of brand LED household energy-saving lamps in the market is generally around 60 yuan each, and there are some products with uneven prices, which makes many consumers dizzy and discouraged. According to industry insiders, the current price of LED components is still relatively high, which has an impact on the popularity and acceptance of LEDs in the entire lighting market.
This year the industry will accelerate the reshuffle
The industry expects that the LED lighting market will start from the early stage, blindly expand, and now the company began to practice and low-end research and development, LED industry will usher in a major reshuffle.
"In the past few years, everyone has been rushing to engage in LEDs, especially the expectations of some non-professionals on LEDs are too high, leading to different understanding of LEDs, resulting in different quality positioning. The industry has real LED lighting design and research and development strength. There are not many companies, many of which are profit-seeking manufacturers, which inevitably lead to a mixed market. Li Jiansheng admits that they have also gone through detours.
As early as 2000, the LED products of CDH Technology were mainly sold to display manufacturers. At that time, the market was just beginning to sprout. Although the market demand is large, the vast majority of “divergence†enterprises generally do not have scale, and production lacks continuity. Therefore, the company’s short-term Dinghui technology has insufficient risk estimation, and bad debts are commonplace, and enterprises have repeatedly fallen into a capital crisis. In 2004, CDH Technology began to focus on the LED lighting industry. In 2006, the company applied for the LED packaging project of the 863 Program of the Ministry of Science and Technology. Since then, the products have been selected by the 2008 Beijing Olympic Games. Today, Dinghui's LED lighting products are used in Shanghai Chenghuang Temple, Expo Theme Pavilion, Yan'an Road Elevated, Nanpu Bridge and 10 bridges along the Suzhou River.
Despite the word-of-mouth, Dinghui Technology found that because the company does not have the channel advantages of downstream lamps, the profit is not obvious. To this end, CDH Technology focuses on R&D, production and sales of resources, and exerts its packaging advantages in the mid-stream of the industry chain, transforming into LED suppliers, focusing on the field of LED packaging, working hard on the quality of products and technologies, and creating a self-owned brand. Hui brand. In fact, the mid-stream package carries the epitaxial chip and the lighting application. As the most important part of the entire LED industry chain, the survival of the packaging enterprise and the quality of the product play an important role in the whole industry. At present, midstream packaging has accounted for about 25%-30% of the entire industrial chain. Li Jiansheng said that the LED light source module based on COB integrated light source technology developed by CDH Technology has achieved stage success and will be mass-produced at the beginning of this year. LED light sources using this technology can be used with lamps of various shapes. At present, 60%-80% of packaging companies have chosen to transform to COB technology, which has become a new trend in domestic LED lighting.
"In the next 3-5 years, LED lighting products will gradually be standardized and standardized, and become a regular product. This period will also usher in the reshuffle of the LED industry. By then, companies with brands, technology and capital strength will Will be based, and some low-end, miscellaneous companies can only survive in the slit." Li Jiansheng believes that when the development of LED lighting industry forms a benign interaction, LED lighting products can only reduce costs, technology, the price of the terminal consumer market will Lower, ordinary people can afford and afford.

Take a few steps to choose the ideal LED lamp
At present, there are a lot of quality LED lamps on the market. How to purchase the ideal LED lamps has become a problem for many consumers. How can I choose the ideal LED fixture?
First of all, we must consider the principle of "simple" products. Lighting should play a finishing touch in the room. Overly complicated shapes and overly complicated colors are not suitable for designing simple rooms.
Secondly, to buy pre-installed LED lamps, most people have experienced the replacement of the ceiling light bulbs: stepping on the table, stepping on the chair, heading 90 degrees, raising the arms over the head to 2.5 meters high or even higher ceiling . When choosing a luminaire, you must consider the convenience of replacing the lamp.
Moreover, LED energy-saving lamps are both energy-saving, good lighting, and do not emit heat, suitable for multi-head lamps. It should be noted that the energy-saving bulbs are mostly standard screws, and the chandeliers have two calibers, one is standard, and the energy-saving bulb can be used; the other is non-standard, and the energy-saving bulb cannot be used.
In addition, we must consider the safety principle of the product, we must choose the LED lamps of the regular manufacturers. Regular products are marked with total load. Depending on the total load, it is possible to determine how many wattages to use, especially for multi-head chandeliers, ie the number of heads × the number of watts per bulb = total load. In addition, rooms with large moisture should be waterproof.
Finally, the coordination problem, the lighting and the overall style of the room should be coordinated, and the multi-lamps in the same room should maintain color coordination or style coordination. Rectangular balconies such as wooden walls, wooden cabinets and wooden ceilings are suitable for a rectangular wooden lamp.2V Lead Acid Battery,Rechargeable Lead Acid Battery,12V 60Ah Lead Acid Battery,Lead Acid Battery For Railway
