LED lights will light up thousands of lights

(Summary description) From October 1, 2012, my country will prohibit the import and sale of general lighting incandescent lamps above 100 watts, which is undoubtedly a good news for LED to enter the civilian market. At the Guangzhou Lighting Exhibition in June, the pace of research and development of LED civilian products suddenly accelerated, forming more abundant product applications. Although most of the scene is still dominated by commercial lighting, many companies have also launched a series of household LED products. These new products have their own emphasis on functions, including cold light and warm light, and some can even adjust the color of the light. Different from the relatively high-end products built in the past, this year, manufacturers began to realize that products that are close to life can be widely used. For example, LED bulbs that can adjust the illumination range, this type of bulbs can adjust the illumination range and angle according to their needs; there are also LED panel lights that can control the color temperature to meet the needs of different scene spaces; there are also very dazzling colors. Decorative effect 64 pixel full color mirror light. It is the general trend of LED lighting to enter the civilian market, and international lighting giants are optimistic about this future market. At this exhibition, the world's second largest optoelectronic semiconductor manufacturer Osram displayed LED products characterized by high quality, flexibility and easy installation. Among them, the newly launched PrevaLED light engine has a color rendering index of up to 90. Through the active color temperature control technology, the light color between the modules is kept highly consistent, and the color cast of LED lighting is solved. Philips' booth design is like a "theater of light". The transparent pyramid on the scene projects 3D images such as "small waist". The most interesting thing is that it launched two LED bulbs suitable for mass consumption this year: the Xpress series has Candle bulbs and spotlights have unique designs and bright brilliance, suitable for decorating an elegant and warm family atmosphere; Huixin series has 6W and 9W bulbs, which are bright, soft and not dazzling, especially suitable for incandescent lamps and energy-saving lamps. replace. The GEInfusionLED module launched by GE this year adopts the smallest screw-in design, which can replace the light source without replacing the entire lamp, which is very convenient to operate. At present, my country's lighting industry is in a period of revolutionary upgrading, incandescent lamps are about to be eliminated, energy-saving lamps are in full swing, and LEDs are in the ascendant. LED lamp is a technological revolution in the lighting industry. An LED lamp can generally save 70% to 80% of electricity than energy-saving lamps, and its life is 4 times that of energy-saving lamps, but the price is 3-4 times that of energy-saving lamps. The high price has become a household LED. barriers to popularization. In this exhibition, Shangshun Lighting has made a new breakthrough in LED civil lighting, a 7W bulb for 3 specials is only 100 yuan. It is equivalent to the price of 33 yuan per bulb. Although it is not cheap compared to traditional incandescent lamps, the price gap has been greatly reduced for mainstream brands of energy-saving lamps. New breakthroughs have been made in key technical bottlenecks In the past few years, although the development prospect of LED is very rapid, the process of household popularization is very slow. "It's not just about 'price' and 'mass production', but in addition to consumer recognition, there are still some technical bottlenecks that have not been broken through." According to Wang Jinsui, chairman of the China Lighting Society, this has led to the emergence of LED bean galls on the market. Compared with traditional lighting, lamps, LED downlights, and LED fluorescent lamps are still far from being as good as claimed. At present, the domestic market is dominated by three-in-one LED products, of which three key elements are: light source, driving power supply, and heat dissipation. The light source is the core part of the whole product. The chip technology is mastered by Europe, America and Japan. Most domestic enterprises adopt the method of purchasing and assembling. Therefore, although the threshold for LED lighting is not high, two key problems must be solved in order to do well - heat dissipation and driving power. In contrast, the challenges of driving power mainly focus on the climatic environment of outdoor lighting, and heat dissipation is a major obstacle for household LEDs to move towards high-power lighting. According to industry insiders, there are many LED assemblers in Zhongshan Guzhen and other places. They simply assemble LED light sources into traditional lamps. The heat dissipation, light decay, secondary optical design, etc. are not satisfactory, and the service life is not long

New breakthroughs have been made in key technical bottlenecks

In the past few years, although the development prospect of LED is very rapid, the process of household popularization is very slow. "It's not just about 'price' and 'mass production', but in addition to consumer recognition, there are still some technical bottlenecks that have not been broken through." According to Wang Jinsui, chairman of the China Lighting Society, this has led to the emergence of LED bean galls on the market. Compared with traditional lighting, lamps, LED downlights, and LED fluorescent lamps are still far from being as good as claimed.

At present, the domestic market is dominated by three-in-one LED products, of which three key elements are: light source, driving power supply, and heat dissipation. The light source is the core part of the whole product. The chip technology is mastered by Europe, America and Japan. Most domestic enterprises adopt the method of purchasing and assembling. Therefore, although the threshold for LED lighting is not high, two key problems must be solved in order to do well - heat dissipation and driving power. In contrast, the challenges of driving power mainly focus on the climatic environment of outdoor lighting, and heat dissipation is a major obstacle for household LEDs to move towards high-power lighting. According to industry insiders, there are many LED assemblers in Zhongshan Guzhen and other places. They simply assemble LED light sources into traditional lamps. The heat dissipation, light decay, secondary optical design, etc. are not satisfactory, and the service life is not long enough. to the ideal value.

The heat dissipation of the LED is not good, which will cause light decay and greatly reduce the lifespan. In this exhibition, the reporter found that there has been a new breakthrough in this technical problem. Youyicheng from Shenzhen has completely overturned the heat dissipation method of ordinary LEDs, and launched the latest fin-type LED indoor lighting series for the first time, including ceiling lights, downlights, flood lights, etc. According to its general manager Shi Yan, it can save more than 40% of aluminum, and its weight is only 1/3 of that of traditional lamps. Through higher efficiency heat conduction and heat dissipation, it can meet the reliability and lifespan requirements of household LEDs. In response to the problem of high-power LED heat dissipation of several hundred watts, the Institute of Engineering Thermophysics of the Chinese Academy of Sciences exhibited a latest research result of the "National 863" plan - the micro-groove group composite phase change cooling technology, which became one of the exhibitions this year. Highlight the highlights. At the scene, the reporter saw this light weight, small size and low cost high-efficiency radiator, its maximum heat dissipation power can be as high as 1KW. Hu Xuegong, the developer of the technology and an expert from the National Natural Science Foundation of China, told reporters that despite its simple and compact shape, its cooling capacity is super strong. times. "It fundamentally solves the technical bottleneck problem of insufficient heat extraction capacity and total heat dissipation power of existing LED radiators."

However, whether LED can enter thousands of households, the key depends on whether the price can be lowered? At present, the chips for the production of LED lamps account for 60% of the total price. With the improvement of luminous efficiency and the expansion of production capacity, the price of chips has dropped by 30% to 40% this year, but there is still considerable space to work hard.

future lighting

Will subvert the concept of lights

On the eve of entering ordinary families, many people are very curious: what will the future LED lights look like? The U.S. Department of Energy has stated that solid-state lighting is the most disruptive innovation in lighting in 50 years. Many people in the industry agree with this, and believe that LED is a subversive product, and it is born to change the life of traditional lighting. At this exhibition, the stunning appearance of some innovative LED products seems to herald a trend: the future of lighting may rewrite the definition of light.

For example, GE launched the thin and stylish Lumination series LED ceiling lights this year. The design is very forward-looking. It uses ultra-thin light guide plates and edge-mounted LED technology to maximize LED efficiency. Compared with fluorescent lamps, it has a longer Longer service life, thinner appearance, more creative shape, stronger dimming ability and design sense, and can also be customized for lighting designers and end users. Incorporating personality and creativity into home lighting decoration, Osram also launched the first OLED lighting product to the market - PirOLED, which uses five detachable ORBEOS flat-panel reflection light sources, and interlace them in the double-spiral lamp holder. Creates great visual effects and also emits nice diffused light.

"Now we see that most of the LED tubes and LED bulbs are basically similar in shape to our traditional fluorescent lamps and bulbs," said Wang Jian, general manager of LED products in GE Lighting Asia Pacific. At the beginning of the application of LED lighting, the main mission was to replace traditional lighting. The main consideration in the design of similar shapes is the idea of ​​​​convenient to replace traditional lights and easy to be accepted by consumers. According to Wu Shengbo, President of Osram Asia Pacific, in fact, LED replacement lamps simply made according to the shape of traditional lighting lamps cannot reflect the best performance and characteristics of LED itself. Everyone.

LED's small size, low power consumption, and strong controllability make it more free to unleash designers' imaginations than traditional lighting. For example, the latest LED lamps series designed by Parisian designer Neil Poulton for Artemide brand, the light halo is equipped with a powerful magnet, which can be attached to the metal lamp bracket, which is very flexible; and QisDesign launched an LED table lamp called "AURELIA" , using a fully transparent material, it looks like an underwater creature-moon jellyfish, which can change into a variety of fascinating light and shadow effects. There is also the "LED Symphony Vase" launched by Philips. With just a touch, the water will be filled with colorful lights, directing and performing a gorgeous and dreamy magic show. With the accumulation of technology and the continuous upgrading of products, intelligent control and innovative design will increase, and the available lighting will not only be lamps!
