大功率LED道路照明光源调光方案的研究

摘要

照明级大功率LED技术的飞速发展，为第四代道路照明带来了前所未有的机遇，成为具有广泛应用前景、性能优良的道路照明光源。在实际使用中，人们不仅对LED道路照明的现场环境、照明舒适度以及照明节能的要求越来越高，而且对道路照明光源的光输出特性、大小等要求也不同。为此，需要对不同照明要求下的LED道路照明光源的调光方案进行深入的研究。%Based on rapid development about the technology of lighting level high power LED, it may bring an unprecedented opportunity for the fourth generation roadway lighting. It will become an excellent performance of roadway lighting with wide application prospect. In practical use, people not only demand highly for the roadway lighting environment, lighting comfort level and lighting energy saving, but also has different requirments for the LED light output characteristics of roadway lighting and lighting intensity. Therefore, we need to do research on the dimmer schemes deeply for the different requests of LED light source of roadway lighting.
