[0106] Example: In the eye health impact assessment method for indoor office environments, the measured indoor illuminance E is 358Lx, the visual comfort level Z is calculated by the formula to be 0.12, and the visual comfort level ZL=0.12 is obtained through dimensionless standardization. Measured minimum illuminance value E m 282Lx and average illuminance value It is 358Lx, the illuminance uniformity F calculated according to the formula is 0.80, and the illuminance uniformity level FL is 0.34 through dimensionless standardization. The maximum luminous flux A measured in the indoor lighting environment is 360Lm / m 2 And the minimum luminous flux B is 269.94Lm / m 2 , the calculated flicker percentage PF is 0.14, and the stroboscopic level PFL is 0.86 after dimensionless normalization. Measured ambient brightness L b 67.32cd / m 2 And the brightness L of the working surface is 85.46cd / m 2 , the calculated brightness distribution LD is 0.79, and further, the dimensionless no...

Abstract

The invention relates to an assessing method for an influence of an office scene illuminating environment on vision health. The method comprises the following steps: measuring present working surface luminance, brightness, color temperature, lamp position, working environment area and illuminating power; adopting seven indexes, including vision comfort level, uniformity of luminance, strobe, brightness distribution, glare, color temperature and lighting power density; calculating the data of the seven indexes by repeatedly measuring the data of the practical illuminating scene; adopting an entropy weight method and confirming an index weight; and lastly, acquiring a comprehensive score. The invention provides the assessing method which is perfect in index system, easy in operation and capable of assessing the vision health for the office scene illuminating environment.

Description

technical field [0001] The invention relates to the field of comprehensive evaluation of office scene lighting environment, in particular to a method for evaluating the impact of office scene lighting environment on visual health by using the entropy weight method. Background technique [0002] With the prosperity of my country's economy and the development of urbanization, lighting equipment has changed from traditional kerosene lamps to more convenient tools such as candles and light bulbs. While lighting tools bring light, they also have an impact on life. Excessive light can also endanger human health. In modern society, most people do production work in office settings, such as classrooms, offices, conference rooms, etc., and the average time for work is relatively longer than before. However, working in an uncoordinated and unhealthy lighting environment for a long time is very harmful to human health, especially visual health, which is most directly affected. With t...
