高效LED筒灯配光、散热一体化设计及能效评价
|
摘要
近年来,各国政府、科技工作者和企事业单位,均在LED(发光二极管)方面作了大量部署和投入,半导体照明受到自问世以来前所未有的重视。随着照明行业对LED技术研发投入的增加,其在生产工艺和性能方面不断提高。于是,LED在照明领域的应用也越来越广泛：从最初的背光源,指示灯发展到了如今LED已基本可替代其他任何类型的电光源,从小功率(1W以下)的LED灯泡到100W以上的LED路灯。其超长寿命及环保等优势让越来越多的照明业界人士选择使用LED作为光源并根据其自身特点开发相应的灯具。
本文首先介绍了一种高效LED筒灯,即将LED作为光源替代传统光源(如卤素灯,荧光灯)设计开发出的新型筒灯,从二次光学设计、散热管理和驱动电路分析选择三方面着手,通过理论计算、软件模拟和测试分析设计开发出一种光,电,热性能均较为理想且在这三方面匹配良好的照明产品。其次,整合热、光,电三方面设计的匹配,对已有部件进行测试分析,验证设计中采用的模拟和计算的合理性与正确性。然后,将高效LED筒灯的测试性能指标与其他光源筒灯进行横向比较,并放入试验场作照明效果的模拟比较。最后,加入经济,成本因素综合分析高效LED筒灯与其他类型光源的性价比,得出最后的结论。
In the past few years, LED(Light Emitting Diode) is becoming more and more noticeable in the lighting industry. Government, scientists and lighting corporations pay more attention on LED lighting than ever before. Consequently, LED has been very competitive in performance for general lighting compared with other main light sources such as fluorescent and halogen lamp.
On the basis of the competence of LED itself, the application is extending from backlight, signal lighting to replacement for all types of light sources. Now more and more lighting experts and designers are tend to select LED as the light sources for lighting fixture development because of its remarkable advantages such as super long lifetime and environment-friendly.
The thesis introduces one type of high-efficiency LED directional lamp, which could be the replacement for current directional lamp having CFL or Halogen as light source. The thesis contains the thermal management and optics design for the LED directional lamp with the theoretical arithmetic and software simulation, then the analysis and selection of driver used. At the end of the article, there will be the evaluation for the designed lamp and comparison with CFL directional lamp in technical and economical fields.
