论文主要研究无症状高原反应区低气压环境下影响视觉舒适度的3个因素:照度水平、光源的相关色温及压力变化。实验中采用3个压力工况分别为1.0 MPa、0.9 MPa、0.8 MPa,所涉及的压力环境属无高原反应症状区域;采用120lx、600 lx和1 000 lx3个照度水平;采用两种光源相关色温分别为3 200 K(暖光)和6 400 K(冷光),有24名在校大学生参与本实验问卷调查。论文通过对参与者在实验过程中所做的各项主观评价,确定在不同压力下照度和相关色温对评价指标中的照明水平、光的明暗比和颜色真实性有显著性影响;并通过拟合回归确定照度与视觉舒适度在不同压力和不同色温下的表达式。
The paper mainly studies three factors affecting visual comfort under low pressure environment of asymptomatic plateau reaction zone: illumination level, correlated color temperature of light source and pressure changes. Three pressure conditions were 1.0 MPa, 0.9 MPa and 0.8 MPa respectively in the experiment. The pressure environment involved was free from the symptoms of altitude sickness. 120 lx, 600 lx and 1000 lx3 illuminance levels were used. The relative color temperature Respectively, 3 200 K (warm light) and 6 400 K (cold light), 24 college students participated in the questionnaire survey. Through the subjective evaluation of the participants during the experiment, the paper determines that the illuminance and the correlated color temperature under different pressures have a significant influence on the illumination level, light-dark ratio and color authenticity of the evaluation index. Return to determine the illumination and visual comfort at different pressures and different color temperature expression.
