LED lights home popularity long way to go

With the rush of replacement of the global LED light source, the LED lighting market has become "bright". It is thanks to favorable policies and good market prospects that many domestic lighting companies have entered the field of LED lighting in recent years.

Behind the prosperity of the industry, the quality of LED lighting products is uneven. The reporter visited the lamp market and learned that the current market has a minimum of 2 yuan and 3 yuan for a 3-watt LED bulb, and a high 50 yuan to 60 yuan. And the same product with the same parameters of different brands of prices will also have a world of difference. Many consumers are confused: Is this a purchase or not? How to choose? Although LED lamps have many advantages such as energy saving and environmental protection, it is still a long time before they really enter into millions of households.

LED lights have long-term advantages

Although incandescent lamps and tungsten halogen lamps for general lighting are inexpensive, they have low luminous efficacy, short life span, and large maintenance workload. What are the advantages of LED home energy-saving lamps? "The same power consumption, the total luminous intensity of LED lamps is 10 times that of incandescent lamps, and 1.5 times that of fluorescent lamps. With the continuous improvement of technology, there is still much room for growth in LED luminous efficiency. The service life of LED lamps is 10 times that of a fluorescent lamp, 100 times that of an incandescent lamp, and almost no maintenance," said the expert.

The reporter learned that buying an LED lamp is equivalent to buying 16 incandescent lamps. Buying an energy-saving lamp is equivalent to the cost of 9 incandescent lamps. From the point of sale price alone, buying LED lights is obviously not as good as energy-saving lamps and incandescent lamps. However, taking into account the power consumption and lamp life and other factors, the LED lamp lighting life is calculated as 15,000 hours, equivalent to 15 incandescent lamps or the sum of 3 energy-saving lamps. In terms of power consumption, incandescent lamps need to consume 600 kWh, energy-saving lamps have 115.5 degrees, and LED lamps only have 69 degrees.

In addition to long-term power saving, the biggest advantage of LED home energy-saving lamps is environmental protection. Ordinary energy-saving lamps made of glass, a light bulb containing about 3-5 mg of mercury, once broken can contaminate about 1,000 tons of water, 300 cubic meters of air, and LED lights are all solid light body, impact resistance is not easy to break, conducive to recycling, and No light pollution and heat radiation, no ultraviolet radiation.

In addition, the LED is completely encapsulated in epoxy resin, which is stronger than light bulbs and fluorescent tubes. There are no loose parts in the lamp body. These features make the LED light bulb not easy to damage. Moreover, the LED lamp does not have a strobe effect, which eliminates the damage caused by the strobe light caused by the traditional light source, visual fatigue, and the like.

Popularization of home long way to go

Although LED lamps have obvious advantages, they have not yet fully entered the civilian and domestic markets. Zhang Jing, who is currently in the process of building a new house, told the reporter that 12 large and small energy-saving lamps were used at home, and more than half used ordinary energy-saving light bulbs, which cost about 130 yuan. "I do not know there are LED home energy-saving lamps, has always thought that only a large screen will use LED lights." The reporter recently saw at the IKEA Baoshan store, a 7-watt fluorescent energy-saving light bulbs are priced at 5.9 yuan , Many consumers have taken several passes.

However, the low market awareness is not the only reason to hinder LED lights from entering the civilian market. It is understood that the price of LED household energy-saving lamps is 3 times higher than that of ordinary energy-saving lamps, and the service life of up to 50,000 hours is not guaranteed. Many consumers prefer the ordinary energy-saving lamps.

Insiders pointed out that LED lighting should enter the general family, but it will take time. Why LED lighting prices are 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 related data, although the number of LED patent applications in the country has increased substantially, and even surpassed the United States as the second largest 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 light bulb is to be used normally for a long time, a material cost of 1W needs more than 9 yuan, and the material cost of a 3 watt bulb is not less than 20 yuan. However, in order to break into the civilian market, many companies began to wage a price war, and many large companies were forced to lower their prices. This kind of behavior that sacrifices quality in order to outperform rivals in price makes LED lighting products unable to win trust. Moreover, it is difficult for the average user to distinguish the product quality and requires professional instruments to perform the inspection. The inspection found that some low-end products have glare and dazzling.

This reporter learned that the market price of branded LED household energy-saving lamps is generally around 60 yuan each, and there are some products with uneven prices, which has made many consumers dizzy and discouraged. According to industry insiders, the current price of LED components is still relatively high, which has affected the popularity and acceptance of LEDs in the entire lighting market.

This year the industry will accelerate the reshuffle

The personage inside course of study estimates, the LED lighting market follows from the early, the blind expansion, until now the enterprise begins to appear the practice, bows the research and development, the LED industry will usher in the big reshuffle.

“In the past few years, we have been rushing to engage in LED, especially some non-professionals have too high expectations of LED, leading to everyone's different understanding of LED, resulting in their own different quality positioning. Industry really has LED lighting design and R & D capabilities The number of companies is small, many are profit-oriented manufacturers, it will inevitably lead to a mixed bag of the entire market." Li Jiansheng frankly, they have gone through detours.

As early as 2000, CDH's LED products were mainly sold to display manufacturers. At that time, the market was just beginning to sprout. Although there is a large market demand, the vast majority of “stray” companies are generally not scaled and lack of continuity in production. As a result, CDH Technology’s short-term projections on risk are inadequate, and bad debts are commonplace, and companies often fall into the financial crisis. In 2004, CDH Technology began to specialize in the LED lighting industry. In 2006, the company applied to the LED packaging project of the 863 Program of the Ministry of Science and Technology. Since then, the product has been selected by the 2008 Beijing Olympic Games. Today, LED lighting products from CDH are used in landmarks such as the Shanghai City God Temple, the World Expo Theme Pavilion, Yan'an Road Elevated, Nanpu Bridge, and 10 bridges along the Suzhou River.

Despite the word of mouth being made, CDH found that because the company did not have the channel advantage of downstream lighting, the profit was not obvious. To this end, CDH focuses its research, development, production, and sales of resources on the advantages of packaging in the middle reaches of the industrial chain, transforms itself into an LED supplier, focuses on the LED packaging industry, works hard on the quality of products and technologies, and creates independent brands. Hui card. In fact, the mid-stream packaging epitaxial epitaxial chip, followed by lighting applications, as the most important part of the entire LED industry chain, the packaging company's survival, product quality plays an important role in the entire 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 Dinghui Technology has achieved success and will be produced at the beginning of this year. The LED light source using this technology can be matched with various shapes of lamps. At present, 60%-80% of the packaging companies have chosen to transition to COB technology, which has also become a new trend of domestic LED lighting.

"In the next 3-5 years, LED lighting products will gradually become standardized and standardized, and will become a regular product. This time will also usher in a major reshuffle of the LED industry. By then, companies with brand, technology, and capital strength will Will be based on, and some low-end, no-name companies can only survive in the slit." Li Jiansheng believes that when the development of LED lighting industry to form a positive interaction, LED lighting products can be reduced with the cost, technology upgrades, the terminal consumer market price will be Lower, the people can afford it and can afford it.

Extend reading a few steps to pick the ideal LED fixture

At present, there are many LED lamps that are not of high quality on the market, and it has become a difficult problem for many consumers to purchase the ideal LED lamps. How can I choose the ideal LED lamp?

First, consider the principle of "simple" products. Lighting in the room should be the finishing touch. Overly complex shapes and overly complex designs are not suitable for designing simple rooms.

Secondly, to purchase LED lamps that are easy to install in advance, most people have experienced the change of ceiling bulbs: stepping on a desk, stepping on a chair, heading a 90-degree angle, raising their arms to a height of 2.5 meters or even higher . Be sure to consider replacing the light bulb when choosing a light fixture.

Moreover, LED energy-saving lamps not only save electricity, lighting and good, do not emit heat, apply multi-head lamps. It should be noted that most of the energy-saving light bulbs are standard screw-type, and the chandeliers have two kinds of calibers, one of which is standard and can use energy-saving light bulbs; the other is non-standard and cannot use energy-saving light bulbs.

In addition, we must consider the issue of product safety, we must choose the regular manufacturers of LED lamps. Regular products are marked with total load. Based on the total load, the number of wattage bulbs used can be determined, especially for multi-head pendants, ie the number of heads × watts per bulb = total load. In addition, waterproof rooms should use waterproof lamps.

Finally, there is the issue of coordination. The overall style of the lighting and the room should be coordinated, while the multi-purpose lamps in the same room should maintain color coordination or style coordination. Such as wooden walls, wooden cabinets, wooden top rectangular balconies, suitable for a rectangular wooden lamp.
