The context of the current global energy shortage concerns rise again, energy conservation is important issue facing our future, is attracting the world’s attention in the lighting field, the application of LED light products, LED as a new kind of green light source products. must be the development trend of the future, the 21st century will enter the LED is the new lighting source era.
Recalling the lighting industry, with the development of science and technology, the illumination light source to the fourth generation of the new green energy from incandescent, fluorescent, HID LED led lights for sale development, which is not only light-emitting principle change, and become more energy-saving, environmental protection, green lighting source. In the global energy crisis, in October 2012 the phase-out of incandescent on the agenda, at the same time, the energy-saving lamps mercury pollution by the majority of the public concern. LED lighting application promotion by countries, governments and enterprises attach importance to this case. However, the wide application of LED lighting is also hindered by the thermal design, materials, electrical accessories, drive power and other technical issues.
The world’s first: the birth of 36 volt lighting products Heyuan
After years of research, a world’s first safer, more energy efficient and more environmentally-friendly lighting products – “36 volt LED lighting led lights for sale system in Heyuan successfully developed and mass production, its inventors the Lianping Motoyoshi town center elementary school teacher LIU Dong-xing, led a research team. It is reported that the 36 volt LED lighting system is composed of two parts of the “220 volts AC-to-DC 36 volt” safety energy-saving switch and 36 volt LED lighting. A big advantage of this invention is that the user does not produce an electric shock hazard. The key does not produce an electric shock hazard in the safety switch. Single invention, had to apply for the 18 national patents and utility model patents.
University of Toronto has developed solutions to control LED lamp heat
LED lights have energy saving, longevity, but its brightness is also far less than a 100-watt incandescent light that comes out of the brightness and LED lights fever life shortened problems also occur with increasing brightness. However, recently, the University of Toronto’s three alumni come together, develop both increase the brightness of the LED lights, LED lights led lights for sale can effectively control the feasibility of solutions of the heat.
The program is actually a specially designed lamp named NanoLight shape similar to the classic 100W bulb, on the surface thereof is covered with a layer of electrically conductive circuit board, and are evenly distributed a certain number of LED lamps, which can be a wide range to provide illumination and to increase the brightness.
U.S. scientists have developed a warm white LED light new materials
As we all know, LED light-emitting diode lights energy efficient and longer life expectancy, but in light blue Designed mainly due to the LED lights, which hindered its popularity in the field of indoor lighting. Developed by scientists at the University of Georgia, USA Today, is said to be the world’s first single phosphor and a single light-emitting unit warm white LED lights. The paper details about this material is published in the latest issue of Optical Science and Applications journal Nature Publishing Group.
Japan developed the the FED technology lighting devices
Tohoku University Graduate School of Environmental Sciences, with the same holding company DowaHoldings announced on January 9, 2013, the two sides jointly develop a cold cathode field electron emission type surface light emitting devices using carbon nanotubes CNT. It was mainly developed for display purposes FEDfiELdemissiondisplay, field emission display technology diverted lighting purposes. Tohoku University, Japan, and the same and the lighting in the exhibition “LIGHTINGJAPAN2013 January 16 ~ 18, 2013, Tokyo Big Sight International Exhibition Center on display at the device related research.
Tamura Seisakusho develop a white LED using gallium oxide
Tamura Seisakusho and its subsidiaries lightwave company exhibited its development of the use of gallium oxide β in January 2013 16 to 18 at the Tokyo Big Sight International Exhibition Center held “Japan 3rd LED and organic EL lighting exhibition -Ga2O3 white LED. The LED by a combination of a blue LED chip on β type-a2O3 substrate produced by the GaN-based semiconductor using a phosphor. The different point is that, when compared to the production and use on a sapphire substrate ordinary blue LED chip, easy to improve the characteristics of the optical output power.
Building large ultra-thin aluminum film to crack deep UV LED problem
Xiamen University by a research team in the the high alumina component nitride deep ultraviolet light-emitting diode surface covered with ultra-thin aluminum film to crack the key challenges restricting the light-emitting devices can be more widely used “light extraction efficiency for the future such devices in industrial applications in areas such as health care, environmental protection, military open to new methods and ideas.
Building Physics and Electrical Engineering Professor 64 and 128 atom supercells the geometric study group’s research team after several years of research, the research team associate professor Huang Kai and doctoral high Na borrow an ultra-thin aluminum film to crack the puzzle. When in a deep ultraviolet light-emitting diode surface coated with a layer of only 5 nm ultra-thin aluminum film layer aluminum film not only does not like a traditional mirror as the device emitted light reflected back, instead cleverly devices to side emitted light is collected through an aluminum film layer, is emitted from the front, to achieve improvement of light extraction efficiency.
