Novaled reports 35 lm/W and 100,000 hours from white OLED
Based on its proprietary PIN OLED technology and materials, Novaleds device exhibits CIE colour coordinates of x,y = 0,43/0,44 (which is yellowish white) with a colour rendering index CRI of 90.
The OLED device is equipped with a blue fluorescent and red/green phosphorescent emitter materials (hybrid approach). For the stacking layer and transport layer, Novaled proprietary materials have been used. The OLED device is equipped with a standard outcoupling enhancement film.
The measurement was carried out in an integrating sphere taking into account only the full forward emission with substrate edges and backside covered, thus corresponding to a real-life application. At a higher brightness level of 4,000 cd/m 2 , the efficiency was 31 lm /W, with no significant changes in colour and CRI value.
"With this achievement Novaled proves once more the advantages of its technology and associated materials for an OLED device combining high performance and long lifetime", says Jan Birnstock, Novaled VP Technology Transfer. "We are working on enhanced outcoupling solutions and large area devices. When associated with a proper phosphorescent blue, we are confident of reaching 100 lm/W combined with a long lifetime in the near future."
Galvanized Monopole tower
Galvanized monopole Towers are used for a variety of communication applications and are ideal for use when zoning is difficult. Monopoles can also be designed as camouflage poles: pine tree poles, flag poles, palm poles and other stealth towers. Many uses include cellular monopoles, wireless internet monopoles, wifi tower, homeland security monopoles, two-way monopoles, and wind tower monopoles.
1. Based on its shapes, it is generally divided into 5 types: Goblet type, cathead type, cathead type, shaped type and barrel type.
Based on application, it can be divided into: Strain tower, straight line tower, angle tower, transposition tower (tower for transposition of wire phase position), terminal tower and crossing tower, etc.
2. Their structural features are: All kinds of towers are of space truss structures; Bard are mainly composed of single equal angle steel or assembling angle steel; Materials are generally Q235(A3F) and Q345(16Mn); Bars are connected by black bolts with shearing force; Entire tower is composed of angle steels, link plates and bolts; A few components like tower base are assemblies of welded steel plates for convenience of hot galvanizing anti-corrosion, transportation and erection.
3. For steel towers that with height below 60m, shackles are mounted on one of main columns for construction people to climb to work. Our Company is a large scale enterprise specializing in manufacturing of 220KV (330KV) electric power steel tower with advanced manufacturing facility and international top-ranking assembly line.
