The scientists have knocked off the door of new generation of LED technology

Business News,Current Affairs,Link Popularity
Rensselaer Polytechnic Institute (RensselaerPolytechnicInstitute) smart lighting engineering technology research center had earlier announced that it has succeeded in integrating the LED and power transistors on the same gallium nitride (GaN). The researchers said the innovation will be knocking on the door of the new generation of LED technology, because it's cheaper and more efficient to manufacture, and the new features and applications far beyond the lighting category.

What the core of the current LED lighting system that LED chips is made ??of gallium nitride, but many external components such as inductors, capacitors, silicon interconnect and wiring are all to be installed or integrated into the chip. The large size wafer integrating these essential elements will again increase the complexity of lighting product design. In addition, the assembly process of these complex LED lighting system is quite slow, not only requires a lot of manual operation, but the price is expensive.

A study led by Rensselaer Polytechnic Institute Electronic Computer and Systems Engineering Professor T.PaulChow is trying to develop a wafer that is completely manufactured by GaN to address these challenges. This fully integrated stand-alone LED chips can simplify the manufacture and reduce assembly and the steps required to automate. In addition, due to adopt a single chip, so the rate of parts failure can also be reduced so that the energy efficiency and cost effectiveness and flexibility in lighting design can be improved.

Chow and research teams directly grew GaN LED structure at the top of the GaN high electron mobility transistors (HEMT). They used several kinds of basic techniques to interconnect the two regions, creating the first independent components what they call HEMT and LED integrated on the same GaN chip. The components was grown in stone substrates marked blue, the light output and optical density showed can be compared to standard GaN LED components. Chow said the study for the development of new emission (lightemittingintegratedcircuit, LEIC) Optoelectronics is very important towards the integration circuit.

The successful development of a new generation of LED technology will be applied in large-scale LED lighting, which can effectively solve the high cost of LED lighting and the problem of low light efficiency, , in addition to outside lighting ,LED lighting can be applied to a wider area to bring us the odd and perfect experience, and commercial outdoor decorative lighting and home lighting is currently most widely used, the LED flood light is popularity in outdoor plazas, parks, railway stations, large commercial buildings, airfield lighting open spaces, Lead lighting www.lead- with the latest LED technology and professional R & D team and production technology insists in producing more environmentally friendly and affordable LED lighting,a large number of a variety of indoor and outdoor lighting such as LED floodlights, LED tunnel lights, LED tube products have been exported to Europe and other countries, Lead lighting together us have been making efforts to create green world.
