【摘要】 本文以 Kubelka- Munk理论为基础 ,对紧凑型荧光灯荧光粉层 -氧化铝保护膜层的光学特性进行了分析。在一定的粒度下 ,计算出了最佳的荧光粉层及保护膜层的厚度。采用保护膜层后 ,只要用较薄的荧光粉层就可得到相同的光输出。理论计算结果和实验数据相符。更多还原

【Abstract】 Based on the theory of Kubelka Munk, the optical properties of phosphor alumina protective layer of compact fluorescent lamp is discussed, and the effect of these two layers’ thickness on the lumen output of lamps is presented. Also the optimum thickness of phosphor layer and protective layer is calculated.更多还原
