Novel LED modules with advanced nano power ICs

由于其更高的效率，安全性和可靠性，发光二极管（led）目前正在取代市场上的其他类型的灯，如白炽灯和紧凑型荧光灯（cfl）。日常照明大大增加了电网的负担。因此，led的效率将在未来的节能中发挥至关重要的作用。在不久的将来，led将因其优越的效率而主导照明市场。由于市场营销和广告的扩张，数字LED标牌行业发展非常迅速。在北美，每年安装超过300万个数字标牌显示器，该行业最近的总收入增长超过60亿美元。因此，高效节能的数字LED标牌不仅可以为经济带来可观的收入，还可以节省能源，创造更清洁的环境。数字LED标牌显示器目前利用单独的电源转换器和LED驱动器为LED提供电力。这种结构效率很低，体积大，重量大，而且会产生大量的热量。该研究计划的主要目标是为未来的数字标牌提供一种全新的电源架构。新架构基于沿LED标牌显示分布的集成解决方案。集成解决方案利用了高频电力电子转换器和纳米技术的最新进展，为该应用提供了高效紧凑的解决方案。这种方法有几个优点，如：更高的效率，紧凑，更少的布线，更简单的散热。这种新颖的架构使未来的数字LED标牌显示能够为每个LED实现最佳性能，从而产生高效的最终产品。这项研究旨在提供“下一代”数字LED标牌，该标牌将利用纳米技术和电力电子技术的最新进展，以更低的成本实现非常高的性能。该研究项目将通过为标识行业提供节能LED电源模块，直接使加拿大能源部门受益。

Due to their higher efficiency, safety, and reliability, Light-Emitting Diodes (LEDs) are currently replacingother kinds of lights on the market, such as incandescent lights and Compact Fluorescent Lamps (CFLs). Everyday lighting significantly contributes to the burden on the power grid. Thus, the efficiency of LEDs will play acrucial role in future energy savings. In the near future, LEDs will dominate the lighting market because oftheir superior efficiency. The digital LED signage industry has been growing very quickly due to the expansionof marketing and advertising. In North America, more than 3 million digital signage displays are installedannually and the industry has recently experienced an overall revenue growth of more than $6 billion. Thus,energy efficient digital LED signage can not only generate substantial revenue for the economy, but will alsosave energy and result in a cleaner environment.Digital LED signage displays currently utilise separate power converters along with LED drivers to provideelectricity for LEDs. This architecture is very inefficient, bulky, heavy and produce a lot of heat. The mainobjective of the proposed research program is to provide an entirely new power architecture for future digitalLED signage. The new architecture is based on an integrated solution distributed along the LED signagedisplay. The integrated solution takes advantage of recent advances in high frequency power electronicconverters, and nano-technology in order to offer a highly efficient and compact solution for this application.This approach has several advantages such as: higher efficiency, compactness, less wiring, and simpler heatremoval. The novel architecture enables future digital LED signage displays to achieve optimal performancefor each individual LED, leading to a highly efficient final product. This research aims to deliver "nextgeneration" digital LED signage that will utilize the new advancements in nano-technology and powerelectronics in order to achieve very high performance at a lower cost. The research program will directlybenefit the Canadian energy sector by providing energy-efficient LED power modules for the signage industry.
