微波硫灯光谱和色温的研究

Research on Light Spectrum and Color Temperature of Microwave Sulfur Lamp

微波硫灯是一种新型的绿色光源,与传统光源相比它有很多优良的性能。本文首先阐述了微波硫灯的工作原理和发光机理,然后主要探讨了微波硫灯光谱的特性,详细解释了色温的计算原理和影响色温的因素,进一步由实验数据分析可得到光谱随硫粉量的增加向长波方向移动,氩气的变化对光谱的影响很小,在一定范围内色温随着硫粉量的增加而下降,同时讨论了氩气量的变化对色温的影响很小的原因。

Microwave sulfur lamp is a new generation environment friendly light source and has more advantages over traditional light source. First we described the principles and mechanism, and then spectrum characteristics of microwave sulfur lamp. We also discuss the method how to calculate the color temperature and the factors which influence the color temperature. Experiment find the light spectrum will shift to longer wavelength and the color temperature will be decreased with the increasing of sulfur powder, and the filling argon pressure will not affect the light spectrum and color temperature.
