"Optrical has developed a new concept for making an LED light panel, which leads to more efficient lighting at lower costs. For producing such light panels today, one has to use slow, serial and expensive methods such as laser machining, mechanical scoring, injection molding or screen printing. Each of these methods have their own issues but the main point is that these are slow and expensive (capital and time extensive). Optrical has, for the first time developed a film that can be adhered to an unpatterned transparent material and it extracts the light coupled of it very efficiently. Such film can be produced on reel to reel basis at very high speeds (upto 40X faster). Using a handmade ""proof of concept"" we have demonstrated that the panel produced by this route can reduce total coupling and absorption losses by upto 1/3 and give upto 12% more lumens. Since the LED lighting manufacturers in Europe/ US today are facing very tough price competition from cheaper Chinese imports, this technology can offer a superior product without having to compete on pricing thus can save a significant number of jobs in UK.In this project we aim to develop the complete process know how for the production of such films and panels leading to a production ready prototype on a reel to reel machine, meeting the commercial specifications. This prototype will fully be tested/ characterized."

“optical已经开发出一种制造LED灯面板的新概念，可以以更低的成本实现更高效的照明。今天，为了生产这样的光板，人们必须使用缓慢、连续和昂贵的方法，如激光加工、机械刻痕、注塑或丝网印刷。每一种方法都有自己的问题，但主要的一点是这些方法都是缓慢和昂贵的（资本和时间的消耗）。光学公司首次开发出了一种薄膜，它可以粘附在无图案的透明材料上，并能非常有效地提取与之耦合的光。这种薄膜可以在卷轴对卷轴的基础上以非常高的速度（高达40倍的速度）生产。通过手工制作的“概念验证”，我们已经证明，通过这种途径生产的面板可以减少高达1/3的总耦合和吸收损失，并提供高达12%的流明。由于欧洲/美国的LED照明制造商今天面临着来自中国进口产品的激烈价格竞争，这项技术可以提供优质的产品，而不必在价格上竞争，因此可以在英国节省大量的工作岗位。在这个项目中，我们的目标是开发生产这种薄膜和面板的完整工艺知识，从而在卷对卷机器上生产出符合商业规格的生产就绪原型。这款原型车将进行全面测试/表征。”
