Reading desk lamp evaluation method based on ergonomic experiment

Abstract

The invention relates to a reading desk lamp evaluation method based on an ergonomic experiment. The reading desk lamp evaluation method comprises the steps of performance evaluation of average illumination and correlated color temperature, comfort level evaluation of average illumination and correlated color temperature, illumination uniformity evaluation, reflected glare evaluation, direct glare evaluation and color rendering property evaluation; an evaluation system is formed by outputs of respective evaluation scores of the six aspects and the weighted average of the evaluation scores; the establishment of performance evaluation of average illumination and correlated color temperature is based on a visual performance experiment; the establishment of comfort level evaluation of average illumination and correlated color temperature is based on a Christopher illumination-color temperature comfort curve; the establishment of illumination uniformity evaluation is based on a national standard; the establishment of reflected glare evaluation is based on a veiling reflected glare reception evaluation experiment; the establishment of direct glare evaluation is based on a national standard; and the establishment of color rendering property evaluation is based on quality factor (QF) indexes in a color quality grade drafted by American national standard institute. By adopting the reading desk lamp evaluation method, the relation between physical parameters and vision quality is established, a quality evaluation result can be output only by measuring the physical parameters of the reading desk lamp, the assessment routine is simplified, and the objectivity and the accuracy are higher.

Description

technical field [0001] The invention belongs to the field of lighting technology, and aims to provide an evaluation method for reading desk lamps based on ergonomics experiments, so as to realize the comprehensive evaluation of the performances of the reading desk lamps in terms of functionality, visual comfort and the like. Background technique [0002] Reading desk lamps, also known as reading and writing desk lamps, have a wide variety of light source types, optical designs and even appearances in the lighting market. With people's attention to eye hygiene, many so-called "eye protection lamps" have appeared on the market, all advertised to protect eyesight and relieve visual fatigue. However, according to the survey, my country's current standards for reading desk lamps only have regulations on illuminance and illuminance uniformity in terms of photometry, and there is no testing standard for "eye protection lamps" that really involves visual comfort. Has blindness. [...
