摘要
为了探讨古代照明在物理、经济、生理和心理方面的影响,进行了两组实验。首先建造了一个暗室(1.3 x 4.5 m, Ht: 2.7 m)。在实验一中,测量了照度和燃油消耗率。日本经典蜡烛、植物油和动物脂肪在1.0 m距离处的产率分别为1.12、0.30-0.62和0.05勒克斯。照度降低到50%左右,这是民间工艺的照明工具。植物油每天燃烧4小时,燃烧时间约为2周至180毫升。实验二对15名年轻女性在模拟蜡烛照明下的视敏度、报纸的可读性、颜色识别等视觉特性进行了测试。视力在0.16勒克斯下为0.42。它需要超过1.44勒克斯来阅读报纸。在辨色测试中,黄绿色是最困难的,银色或长波范围的颜色是容易的。
Study on illuminance and visual properties of flammable illumination.
In order to investigate the physical, economical, physiological and psychological aspects regarding ancient lighting, two series of experiment were performed. At first a darkroom (1.3 x 4.5 m, Ht: 2.7 m) was constructed. In experiment I, illuminance and consumption rate of fuel were measured. The Japanese classic candle, plant oil and animal fat yield 1.12, 0.30-0.62 and 0.05 lux at 1.0 m distance, respectively. The illuminance was reduced to about 50% by and on which was a lighting tool of folkcraft. The burning duration of plant oil was about two weeks to 180 ml when it burned 4 hours per one day. In experiment II, 15 young females were examined regarding the visual properties such as visual acuity, readability of newspaper and discrimination of color under the simulated illumination of candle. The visual acuity was 0.42 under 0.16 lux. It needed more than 1.44 lux to read a newspaper. In the color discrimination test, yellowish green was most difficult, silver or long wave range colors were easy.
