    LED industry, "price war" is becoming increasingly fierce, how to find a way out of business? This forces us to do some technical thinking. Summary of 12 kinds of new LED technology and application to see which is your food?
    Can be completely covered with the visible wavelength "standard LED"
Japan Industrial Technology Research Institute announced that with the Nichia Chemical Industry jointly developed to cover the entire visible light range of LED light source. The two agencies use a plurality of LED elements with different center wavelengths and a variety of fluorescent materials to develop a light source with sufficient light intensity over the entire visible range (380nm ~ 720nm). Since this light source can be used as a standard light source for evaluating solid element lighting fixtures, the results of this development are named "standard LEDs". It was revealed that there was no standard light source that could be used for high-precision spectroscopic measurements of solid element lighting fixtures and covered the entire visible range.

     In view of the use of the "standard LED" in the manufacture and development of LEDs, high-precision features of solid-state lighting fixtures can be evaluated and are expected to contribute to accelerating product development and improving performance. In this regard, Nichia Chemical Industry said that since then will promote the "standard LED" production ready. Japan Industrial Research Institute, said it will further improve the "standard LED" in the development of the spectrum of precision measurement technology used to study the development of surface light source and ultraviolet light and infrared light range of light source evaluation technology.
Single layered columnar LEDs produce a single pixel white light
    Production of white LED, not the use of white phosphor (phosphor) coating coated with monochrome LED, is the red, green and blue LED mixed together? Researchers at the University of Taiwan do not think that they are developing a technology that produces a single pixel (pix) of white light from a single tiered-column LED. The basic concept is that quantumwells are embedded in gallium nitride (GaN) and indium gallium nitride (In GaN) nano-rods that grow on the same substrate.

     According to the researchers, those LED arrays are based on organometallic chemical vapor deposition (MOCVD) pulse growth method, can achieve better than the use of traditional process technology luminescence performance. They have grown in multi-section nanocolumns with different cross-sectional sizes to develop a wider range of emission spectra compared to single nanocolumns, Exempt white light from the phosphor. At the same time, the research team is also developing the surface plasma to enhance the luminous, improve efficiency and avoid the damping effect (droopeffect), and by increasing the bandwidth of the transmission of visible high-speed communication.
     Newly designed polymer OLED lighting products

     Xiu Mi is a mobile content production and publishing platform, providing a wealth of templates and easy to use experience, so you quickly create a very innovative content, to impress your crowd.
     UV LED technology solar charging water purification device
     Lund University Water Resources Engineering Professor Kenneth? "At present, 750 million people worldwide are unable to obtain clean water and provide a huge challenge for safe drinking water and one of the most important goals of mankind." In view of this, he was co-founded with an engineer in 2013 Of the environmental company Watersprint, and developed a use of solar charging and UV LED technology, water purification equipment, the equipment provided by the clean water far more than the smart grid can cover the area.

    It is understood that the technology is through UV LED technology and intelligent software and Wi-Fi combination to purify water quality. The 12 volt system is very effective and can be run in a single solar panel. Solar cells can also be self-charging, so the portable device can also be used in rural areas without electricity. This compact and portable solar cell station has been housed in rural areas of Bangladesh. Last year in October has installed the first water purification device, there are nine water purification equipment has been delivered to the Bangladesh project.
    Apple VR head or will use micro LED display
    Last May, Apple acquired the mini-LED display technology industry leader in the LuxVue company, the outside world generally believe that LuxVue will achieve a breakthrough in the display technology. Apple will be how to use this technology has become a topic of public relish, but the current position is no clue. Apple has previously announced that the 2017 iPhone screen supply chain will be replaced by OLED, AppleWatch screen also changed to the use of OLED. Micro LED display in the Apple Empire's territory where, no doubt even more complicated and confusing.

    It is speculated that the micro-LED technology is likely to be used for "direct-type display", including applications in the field of enhanced reality and virtual reality, such as head show. EXALOS CEO said that for the next generation of display, micro-LED will be to improve the performance and brightness of the key components. LED micro-display is ideal for use is to wear systems, because the LED mini-display has a small footprint, low energy consumption, high contrast and high brightness characteristics. Although the current advanced technology into the fans, but in the near future, will appear in a consumer version and professional version of the product.
     Ski suit with 7,000 Philips LED decorative lights
     In a recent video, a team of skiers dressed in 7,000 LED lights decorated clothing, from the color spotlight under the slope of the slide, it was directed, this is the high-tech lighting to the gorgeous skiing. It is reported that this 12-minute micro-film shot in British Columbia and Alaska Golden Alps resort. In order to illuminate the entire huge mountain slope, the staff used eight 4000-watt headlamps and other small lights. Using unmanned aerial vehicles and fixed camera photographed the skiers slide down from the scene.

    In fact, this is a micro-film to promote Philips Ambilight TV. Among them, each piece of golf shoes on the ski dress are sewn thousands of LED lights, this fabric is waterproof material and connect the candy-sized battery. The film's film took five weeks, costing £ 9,000, at minus 15 degrees Fahrenheit. Although the cost is not small, but Philips hopes in this way to promote its overflow color stream TV lighting technology superiority, and to show the world how to completely change the human experience.
     Silicon Substrate Project won the National Technology Invention Award
It is understood that the current international LED lighting technology line a total of three: sapphire substrate, silicon carbide substrate and silicon substrate gallium nitride-based LED technology ("silicon substrate LED technology") line. The first two routes are called the industry's mainstream technical route and the "nobility" route, the core invention patents were Japan, the United States monopoly. Silicon substrate LED technology is the meaning of the birth of a new path, so that China has the third international LED lighting technology line to a new light source of the posture breakthrough barriers to get rid of patent disputes.
    Preparation of high light efficiency on the silicon gan-based LED, has always been the goal of academic efforts. However, due to silicon and gan huge lattice mismatch and thermal mismatch caused by the epitaxial film cracking, poor crystal quality, and substrate opacity caused by low efficiency of light and other issues have long been resolved, the silicon substrate gan-based LED route Almost sentenced to "death". In fact, as early as 30 years ago, the United States IBM in the development of silicon substrate LED technology, but "halfway" announced to give up. Chinese researchers are in this situation to the technology "pick up". After thousands of experiments, continuous technical research, since 2003, the R & D team has finally made a breakthrough, thus developing a silicon substrate gallium nitride-based LED materials and device technology.
