摘要：

为评价儿童夜行安全服装的可视性能,更好地发挥安全服装的警示和提醒功能,采用彩色夜光纤维和夜光面料制备4件儿童夜行安全服装样衣,通过测量样衣的发射光谱及余辉亮度,计算得到2°和10°视场样衣的等效亮度,研究实测亮度和等效亮度之间的关系。结果表明:样衣等效亮度均大于实测亮度,条纹面料样衣的可视效率最高,其次为绣花样衣,绒布样衣可视效率最差,多色夜光面料样衣比单色夜光面料样衣的可视效率好;夜光纤维的等效亮度衰减变化趋势与实测亮度相似,等效亮度值随时间逐渐递减,一定时间(800 s)后其值趋于稳定,不再发生明显变化。

Abstract:

In order to evaluate the visibility of children nocturnal safety garments with warning and reminding functions, four children nocturnal safety garments were made of colored luminous fiber and luminous fabrics. By measuring the emission spectrum and the afterglow decay, the equivalent luminance of samples were calculated with the view field of 2°and 10°. Then, the relationship between the equivalent luminance of samples and the measured luminance of samples was studied. The results show that the value of the equivalent luminance of samples are greater than that of the measured luminance. The visual efficiency of the stripe fabric sample is the highest, followed by embroidered garment sample and flannelette fabric sample, and the visual efficiency of samples made of multicolor luminous fiber is better than those made of monochrome luminous fiber. The attenuation trend of equivalent luminance of samples is similar to that of measured luminance of samples. The value of equivalent luminance decreases gradually with time until it tends to be stable and has no significant change in a certain time (about 800 s).

Key words: luminous fiber, safety garment, equivalent luminance, visual efficiency
