When it comes to LEDs, many people think of LCD TVs or display screens in front of mall galleries. As an LED light source that is widely used in industrial and outdoor lighting, as the technology continues to mature, it has begun to extend to the field of indoor lighting. So, what is the current development status of LED home lighting? When can we enter our family? Recently, at the Qingdao International Lighting and LED Exhibition held at the Qingdao International Convention and Exhibition Center, the reporter interviewed the person in charge of the participating companies.
LED green lighting advantage is nowadays, small to all kinds of holiday lights, street lights, notebooks and TV backlighting, large to the opening ceremony of the Shanghai World Expo that piece of 300 meters long and 30 meters high, the world's largest outdoor LED display, LED products have entered Everyone lives in every aspect.
At this year's Qingdao International Lighting & LED Exhibition, a group of well-designed lighting fixtures attracted the attention of many participants. It is understood that this group of South Korean imports of LED multi-function lights not only soft and beautiful appearance, but also can change the color, with aroma and clean air function.
Yu Fengxian, Sales Department of Qingdao Xiejin Electronics Co., Ltd. told reporters that LED lamps have the advantages of low power consumption and long life compared with traditional energy-saving lamps. “The Korean original LED lamp we sell has a semi-permanent life, that is to say it is no problem to use it for more than ten years. Although the price is still somewhat high, but the LED lamp replaces the traditional energy-saving lamp for home lighting, only time problem."
According to the relevant personages of the exhibition, as a crystallization of high technology, compared to traditional lighting products, LED light source has the advantages of small size, low power consumption, long life, high brightness, low heat, low carbon environmental protection, and durability. The LED industry as the country's newly fostered upstart industry is showing its huge market potential and rapid growth. At present, some companies have begun to introduce LED lamps for home lighting, and launched a new trend of green low-carbon home lighting.
Disadvantages hinder the development of the industry Although the prospect of LED applications in the field of home lighting is promising, LED lights sold in the current market have affected consumers to a large extent due to high prices, backward processes, and market confusion. Confidence in such products.
LED lights have no competitive advantage in terms of price because of their own cost. Although LED lamps meet the concept of low-carbon consumer green consumption, the price of hundreds of yuan still makes many customers discourage. In response to this phenomenon, Yu Fengxian calculated another account for the reporter:
"A lot of people think that the price of LED lights is too high to be acceptable, but if considered from a long-term perspective, LED lights will save more money and energy than traditional light bulbs. We can calculate that ordinary incandescent lamps will not exceed 2,000 hours of service life. On the spiral energy-saving lamps up to no more than 8000 hours.Compared to these, LED lamps can theoretically use 1000000 hours, almost no replacement.And from a power-saving point of view, the LED light source in the same lighting effect than the traditional light source energy saving 80% Above, these add up to a calculation, in fact, it is more appropriate to buy LED lights."
At present, most of the domestic high-end LED lighting product manufacturers use chips produced by overseas manufacturers. "The domestic chip manufacturing companies lack core technology, and the domestic chips do not meet the standards in quality and have to import chips. This is one of the reasons for the high price of LED lighting products." Participated in the lighting exhibition in Guangzhou, New York Desheng Optoelectronics Technology Co., Ltd. Sales Engineer Huang Shaoqian introduced.
Many people who bought LED lights often complained on the Internet that they had just started to use the lights they had bought. However, after less than half a year, the lights dizzy and dizzy, and they failed to achieve the lighting effect. They had to replace them. . There are also many complaints that LED products have poor heat dissipation, which is no different from ordinary light bulbs.
In response to this phenomenon, Huang Shaoqian explained to the reporter, “Some companies have caused light fades because of the problems of design and manufacturing standards, which affects the lifespan of LEDs. The heat dissipation is always a problem for LED products. Every manufacturer is trying The method reduces the thermal resistance of the LED light source, but so far it has not been well resolved due to technical reasons."
In addition, due to the non-standard market and the lack of specific industry standards, many domestic manufacturers competed indiscriminately and competed with their counterparties at a low price for the sake of reducing the quality of their products. Therefore, many people bought “short-lived†and “hotâ€. LED lights.
Core technologies and standards are the key Although there are many problems with LED indoor light source products on the market today, the trend of replacing traditional light sources is already unstoppable.
It is understood that with the increase in the number of processes and quantities of LED chips, a larger wafer fabrication process will be used to reduce costs, and in recent years it has been reduced by 20% each year. The cost of LED lighting is mainly in the LED chip. As long as the price of the chip is reduced, the LED lamp can be reduced to the energy-saving lamp at the current stage, and indoor lighting will naturally bloom everywhere.
At present, China’s government departments are increasing the research and development of independent LED chip technology, and a large number of chip R&D and production enterprises have emerged, such as Sanan Optoelectronics and Shanghai Blue Ray. The quality of domestic chips is continuously improving. Problems such as too much light failure and poor heat dissipation are also expected to be well resolved.
"Using a nitride wafer as a substrate material for LED lighting equipment, the luminous efficiency can be doubled and the lifetime can be greatly extended. Within three years, our gallium nitride substrate material is expected to become industrialized. Our goal is to replace Some sapphire and other substrate materials really change the LED's industrial chain,†said Tsao Dejin, founder of Qingdao Aluminum Aluminum Opto Semiconductor Co., Ltd.
The lack of standards has always been a bottleneck in the development of the LED industry. To overcome this obstacle and regulate the LED product market, the Ministry of Industry and Information Technology approved the release of nine industries covering LED materials, chips, devices, and related inspection and test methods at the beginning of last year. standard. Then, the National Standardization Management Committee also issued an announcement: Prior to this, the six draft LED-related standards submitted by the National Lighting Standardization Technical Committee passed the examination and approval and became the national standard. Together with the two mandatory national standards that were introduced before, a total of eight items were issued. The eight standards have been gradually implemented and will gradually strengthen the supervision and regulation of the LED industry.
The industry believes that the development of independent chip technology, to create their own advantage of the lighting brand is the continuing development of the lighting industry, lighting companies to deal with the important issues of competition. It is believed that in the near future, green low-carbon LED light sources will illuminate the good life of millions of households.
