LED lighting has many advantages, but it has been difficult to carry out the promotion all the time. It has never been able to break through the cost. The high price has made the ordinary people discouraged. Today, low-carbon technology has been greatly promoted, LED lighting has been increasingly applied to the fields of architecture, landscape and municipal engineering. The reason why there is such a large distance from ordinary families is because the core technology of LED is mastered. In the hands of foreigners, the price of domestic LED products remains high. In addition, domestic LED manufacturers mainly aim at market areas such as architectural landscape lighting, large-screen display, traffic signal lights, etc., and are insufficiently developed for ordinary people.
A 1.2-meter-long LED tube has a retail price of nearly 200 yuan. Even if people know that it is energy-saving, environmentally friendly, and has a longer service life, most of them will choose traditional fluorescent tubes that sell for less than 10 yuan. Recently, at the branch of the Lighting Society of the 8th Youth Academic Annual Meeting in Nanjing, relevant experts broke the biggest bottleneck that restricted LEDs from entering the homes of ordinary people. Experts analyze that with the maturity of technology, the cost of LED lighting fixtures will continue to decrease within three to five years, reaching the civilian price acceptable to ordinary consumers, and truly achieving popularity in the home field.
Zhou Ye, general manager of Jiangsu Branch of Zhen Mingli Holdings Co., Ltd., who has been engaged in LED lighting research and development for a long time, revealed that three years ago, the 40-watt LED tube factory price was about 300 yuan, and most of the products are now sold at 140,160 yuan. Although most of the LED core technologies and patents are currently in the hands of foreign companies, domestic companies have not given up on research in this area, and have achieved some results in recent years. Before 2002, domestic LED chips were completely dependent on imports. In 2006, the localization rate reached 44. He is very optimistic that the survey shows that the price of ordinary household LED lamps can be accepted as long as the price drops to 4,060 yuan. By then, LED green lighting will truly replace energy-saving lamps and enter every household.
LED lights have better performance than energy-saving lamps 80, a home 5 watt LED bulb, can replace 1 11 watt energy-saving lamps, and a 90-watt LED street lamp lighting effect is equivalent to 250 watts HPS. Moreover, the LED lamp is completely free of mercury pollution, does not pollute the soil and groundwater, and is highly consistent with the green concept of energy saving and environmental protection.
The cost of LED lights will fall in the next five years. 80% of the securities industry analyst Song Jia said that the cost reduction is the key to the opening of the LED lighting market. At present, China's LED has the lowest cost but not enough cheap, and there are five main ways to reduce costs.
LED is about to usher in the third round of growth cycle, the first round of growth cycle: mobile phone application; the second round of growth cycle: medium and large size LCD backlight; the third round of growth cycle: general lighting. LCD backlighting is the main driving force, and the era of general lighting is coming. The backlight market is 5.6 billion US dollars; the automotive lighting market is 18 billion US dollars; the general lighting market is 70 billion US dollars, 12 times that of the backlight market, and will reach 120 billion US dollars by 2020.
Song Jia believes that cost reduction is the key to opening general lighting. At present, China's LED lighting has the lowest cost, but the cost recovery period is more than 9 years; LED cost recovery period is less than 2 to 3 years is the explosion point of the lighting market.
He said that the cost of LED lighting will fall by 80% in the next five years. The main ways are as follows:
Path 1: Increase luminous efficiency;
Path 2: increase in yield;
Path 3: wafer and equipment upgrades;
Pathway four: package scale and technological innovation;
Path 5: The entire industry chain reduces profit margins.
LED general lighting 2013 outbreak forecast 2015 LED chip cost dropped from the current 20 US dollars / klm to 2.9 US dollars / klm, lighting costs dropped to 15 US dollars / klm;
At the end of 2012, the cost recovery period of cool white LEDs was less than 3 years;
At the end of 2013, the cost recovery period of warm white LEDs was less than 3 years.
The popularity of LED lights also requires the environmental protection of the audience. Now traditional lighting companies have invested in LED development and application, and promote the use of low-energy, high-brightness, low-calorie, environmentally-friendly and durable LED lights in home lighting.
However, from the perspective of the big environment, the overall home market is now in a downturn. Before LED lighting has entered the era of clothing prices, the resistance of LED home lighting should not be underestimated. At present, the rising cost of the industry has greatly affected the quality and credibility of LED lamps, weakened the determination and belief of consumers, and has had a very bad impact on the development of the entire industry. Not only is the small enterprise encountering a quality crisis, but the brand enterprises are also facing Credibility crisis, in the future development of the LED lighting market, we must pay more attention to the high-quality functions of products.
Recently, we learned that while major companies shouted LED new appearances, there are still few businesses in the market that operate LED lights. Only a few of them are engaged in LED light boxes, LED advertising signs and some lighting decoration projects. Very few shops that specialize in LED indoor products. Some big-brand companies have already listed some LED products one after another. However, the price is expensive, which makes LED promotion difficult.
At present, LED lamps for home use mainly include bulb lamps, fluorescent tube lamps, spotlights, table lamps, etc. Among them, bulb lamps are mainly 3W, 5W, 9W and other models. It is understood that the current price of a 5W energy-saving lamp on the market is about 100 yuan, and the price of energy-saving lamps of some big brands is about 30 yuan, which is several times different. I am still waiting for the price in the market to drop to 50 yuan or less. In the interview, a citizen who is purchasing an energy-saving light bulb said. There are still some problems in the mass promotion of indoor lighting, mainly because of the high cost, it is difficult to spread to every household. However, in large supermarkets and enterprises with long lighting time, because of the significant power saving effect, the cost can be recovered within two years, so it is welcomed by many users. An industry source said.
According to some lighting store owners, they understand that this is a sunny industry, but currently it is still relatively exclusive for LED products, which reflects the cost of operating costs, the cost of equal power lamps is 6 to 20 times that of energy-saving lamps, which leads to a If you come to the capital, you don’t dare to stock up. Second, the product has a long service life and fewer repeat customers. The whole industry is the same. When you talk about energy saving, the people are very much in favor; once you quote, you will not be heard immediately.
