LED道路灯具设计探讨

近年来,随着LED光效的迅速提高,LED凭借与传统光源相比寿命长、显色性好、近似点光源、定向发光、节能环保等诸多优点,使道路照明行业看到了其应用于道路灯具的潜力。但是在LED道路灯具的设计中仍有许多技术难题需要克服和解决,尤其是对二次光学设计、散热设计、驱动电源等关键技术需要进行深入地研究和综合地权衡,这样才能更好地推进LED在道路照明中的应用。

Discussion on the Design of LED Road Lamp

In recent years, LED lamp has shown great potentiality in road illuminating industry with its speedy improvement of luminous efficiency, which predominates with its characters such as long life, good color rendering properties, approximately spotlight, oriented irradiance, energy - saving and environmental protection compared with traditional light sources. However, we are still confronted with lots of technical problems needing to be overcome and solved during the design for LED road lamp, especially some critical technologies, for instance, second optical design, heat dissipation, power drive and so on. We will take a long time to carry out deep study and general identification in a large scope in order to better promote the LED＇s application in road illuminating.
