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.

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关键作用。在不久的将来，LED将主导照明市场，因为它们的上级效率。数字LED广告牌行业由于营销和广告的扩展而增长非常迅速。在北美，每年安装超过300万台数字标牌显示器，该行业最近经历了超过60亿美元的整体收入增长。因此，高能效的数字LED标牌不仅可以为经济带来可观的收入，而且还可以节省能源并产生更清洁的环境。数字LED标牌显示器目前利用单独的电源转换器沿着LED驱动器来为LED提供电力。这种架构非常低效，体积庞大，沉重，并产生大量热量。拟议研究计划的主要目标是为未来的数字LED标牌提供全新的电源架构。新的架构是基于一个集成的解决方案分布沿着LED signagepisode。该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。这种方法具有以下几个优点：效率更高，结构紧凑，布线更少，散热更简单。新颖的架构使未来的数字LED标牌显示器能够为每个单独的LED实现最佳的性能，从而产生高效的最终产品。这项研究的目的是提供“下一代”数字LED显示屏，将利用纳米技术和电力电子学的新进展，以实现以较低的成本非常高的性能。该研究计划将通过为标牌行业提供节能的LED电源模块，直接使加拿大能源部门受益。
