And holding (Group) Co. Ltd. (Tokyo Chiyoda outside Kanda 4 chome 14 times 1, registered capital: 36 billion 400 million yen Chairman: Yamada Jeonwoong) subsidiary and Electronic Technology Co. Ltd. (address with registered capital: 1 billion yen Chairman: Otsuka Aki), the successful development of the center wavelength of the 310nm band, reached up to 90mW the output power level of the world's leading 1mm * 1mm deep UV LED chip. Deep ultraviolet (UVB) in the 310nm band is widely used in the fields of resin coating hardening and skin treatment. With the change of traditional light sources such as mercury lamp and excimer lamp to LED, the future may be non mercury, the direction of the development of portable equipment. And, because of the advantages of long life, power saving and so on, we are looking forward to the breakthrough in more applications.                         ♦ 310nm band deep UV LED chip With the combination of Tonghe Electronic Technology Co., Ltd. and the

FAIZ RAHMAN of the University of Ohio, Ohio, believes switching from LEDs to lasers for phosphor-pumped white light sources increases efficiency, extends lifetime and produces highly collimated beams. Currently, laser sources are based on semi-polar GaN laser diodes and incorporate advanced phosphor technology. As the laser focuses on a tiny spot on the phosphor that emits light and converts it to white light, the light source can output safe and highly collimated white light. Laser-based methods, whose properties include a much higher temperature rise than LEDs. Laser pumping is also practical because devices that emit in the near ultraviolet are readily available and can function effectively. The process of moving from LED to laser does not happen overnight. In contrast, LED-based luminaires will remain the primary means of generating white light for the foreseeable future. However, laser diode-based solid-state lighting systems have found application in high-brightness lighting

Outdoor lighting is one of the first few types of lighting that turns to LEDs earlier, and the energy efficiency benefits, albeit highly, have given rise to new challenges that will keep outdoor lighting designers on standby. The following are the top 10 challenges in the new year. Glare This problem will not disappear. People are increasingly realizing that too many poorly-controlled lamps are installed when the LED is beginning to popularize. And in some places, low-color lighting is also popular with residents dislike. 2. The end of private initiative financing (PFI) Large-scale private financing LED era is coming to an end. But when the dust settles, authorities in some places are still wondering whether these items are worth the money, at the expense of lighting quality. 3 electric car charging The general government believes that its street lamp network can provide the perfect charging solution for the coming era of electric vehicles. However, this is not the case, t

Japan's Yomiuri Shimbun reported that Japanese researchers, lawmakers and business people all hope that LED products can be made from rare earth metals in the deep sea off the coast of Japan and applied to Japan's Olympic and Paralympic Games in 2020. Rare earth metals are highly concentrated in the outer seas of Minami Torishima, Japan's easternmost island of Ogasawara. Rare earths in the seabed 5,000 meters deep are estimated to be enough for 200 years in Japan. Yasuhiro Kato, a professor at the University of Tokyo in Japan, and his research team succeeded in extracting (Yttrium) and (Cerium) from rare earth metals in the sea out of South Island as LED luminescent materials. Several Liberal Democrats have proposed to the government that they hope to use the LEDs for the Olympic Games in Japan. The government is also considering commercializing the LEDs for use in Olympic venues to show foreign guests the richness of Japan's marine resources. If large-scale ex

Optical performance (light distribution) The optical properties of LED lamps mainly relate to the performance requirements in terms of luminosity, spectrum and colorimetry. According to the industry standard "semiconductor light-emitting diode test method", there are luminous peak wavelength, spectral radiation bandwidth, axial luminous intensity angle, luminous flux, radiant flux, luminous efficiency, chromaticity coordinates, correlated color temperature, color purity and dominant wavelength Color index and other parameters. LED lamp commonly used white LED, color temperature, color rendering index and illumination is particularly important, it is an important indicator of lighting atmosphere and the effect, and the color purity and the main wavelength is generally not required.     Thermal properties (structure) Lighting LED lighting efficiency and power supply is one of the key LED industry, at the same time, LED PN junction temperature and the case of the cool
