项目摘要

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.

由于发光二极管 (LED) 具有更高的效率、安全性和可靠性，目前正在取代市场上的其他类型的灯，例如白炽灯和紧凑型荧光灯 (CFL)。日常照明极大地增加了电网的负担。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 将因其卓越的效率而主导照明市场。由于营销和广告的扩张，数字 LED 标牌行业一直在快速增长。在北美，每年安装的数字标牌显示器超过 300 万台，该行业最近的总体收入增长超过 60 亿美元。因此，节能的数字 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创造更清洁的环境。数字 LED 标牌显示器目前使用单独的电源转换器和 LED 驱动器来为 LED 提供电力。这种架构效率非常低、体积大、重并且产生大量热量。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。新架构基于 LED 标牌显示屏分布的集成解决方案。该集成解决方案利用高频电力电子转换器和纳米技术的最新进展，为该应用提供高效、紧凑的解决方案。这种方法具有多种优点，例如：效率更高、结构紧凑、接线更少、更简单除热。这种新颖的架构使未来的数字 LED 标牌显示器能够实现每个 LED 的最佳性能，从而实现高效的最终产品。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学的新进步，以较低的成本实现非常高的性能。该研究计划将为标牌行业提供节能的 LED 电源模块，从而使加拿大能源行业直接受益。
