5 years warranty led street light

Three alumni of the 5 years warranty led street light have jointly developed a feasible solution that can not only improve the brightness of LED lights, but also effectively control the heat generated by LED lights., Ltd. Japan has developed FED technology lighting devices., Ltd. Tohoku University and Dowa will be at the lighting exhibition '

LIGHTINGJAPAN2013' On , the research results related to the device were exhibited at the Ariake International Convention and Exhibition Center in Tokyo. However, the widespread application of LED lighting is still hindered by technical issues such as heat dissipation design, materials, electrical accessories, and driving power. The FEDfiELdemissiondisplay, which was previously developed mainly for display applications, is transferred to the field emission display technology for lighting applications. At the same time, the mercury pollution of energy-saving lamps was concerned by the general public.

American scientists have developed new materials for warm white LED lamps., Ltd. Japan’s Tohoku University Graduate School of Environmental Sciences and Dowa Holdings, Dowa Holdings, announced on January 9, 2013 that they have jointly developed a cold cathode field electron emission surface luminescence using carbon nanotubes. and its subsidiary Lightwave Co. Not only has the light-emitting principle changed, but also the lighting sources have become more energy-saving, environmentally friendly and green
