一、前言对高压钠灯进行的研究表明,高压钠灯的效率与放电管的管壁温度有密切关系,而在对灯用材料的研究中发现,管壁温度是引起氧化铝升华、玻壳发黑从而影响钠灯寿命的一个重要因素。在高压钠灯机理的研究中,为了计算辐射转移和热导,壁温也是一个不可缺少的输入参量。因此,找到一种有效而简捷的壁温测试方法,对高压钠灯的改进、研制和推广都有着重要的实际意义。本文采用光谱方法测量高压钠灯的壁温,
I. Introduction The research on HPS lamp shows that the efficiency of HPS lamp is closely related to the tube wall temperature of the discharge tube. However, in the study of lamp materials, it is found that the tube wall temperature is caused by the sublimation of alumina, Thus affecting the life of sodium lamp is an important factor. In the study of the mechanism of high-pressure sodium lamp, the wall temperature is also an indispensable input parameter in order to calculate the radiation transfer and heat conduction. Therefore, finding an effective and simple wall temperature test method is of great practical significance for the improvement, development and popularization of HPS lamps. In this paper, the spectral method to measure the high pressure sodium lamp wall temperature,
