Title        Test of the parameters for Artificial Light Source                    

Abstract

With the worsening of human living environment, people's awareness of health and environmental protection is gradually being strengthened, light pollution has become an important problem to be solved. Frequency of blinking some characteristics of various lighting source is widely used currently exist in varying degrees of health vision system, which seriously harm people. This paper studies the characteristics of common artificial light source and luminous mechanism, analyzed the reasons and the effects of light pollution. For the most serious strobe light pollution, made a detailed introduction and analysis. At the same time selects different types of lighting, testing and analysis of the scintillation characteristics parameters of the frequency, stroboscopic quantitative test data so that the light source, in order to facilitate the selection of lighting model is suitable for the luminescence mechanism and indoor lighting, provide the experimental basis for the research and development of energy-saving green light source. This paper not only presents methods of testing strobe, and control to solve the problem of light pollution strobe and also put forward some solutions, finally introduces two kinds of green energy-saving light source model.

1．1 人眼视觉特性

人眼对480~640nm区间色光的色调分辨力较高，其中，对500nm和600nm两个波长来说，只要波长变化1nm，便可分辨出色调的变化。而从655nm的红色到可见光谱长波末端，以及从430nm的紫色到可见光谱短波末端，人眼几乎感觉不到差别。
