| 内容記述 | As a result of repeated experiments, it is clear that within the integral calculus globe, it is possible to obtain a homogeneous light which causes the least fatigue. After four persons had read some books for one hour per person inside the integral calculus globe clinic room, their degree of fatigue were measured by using the flicker fatigue-measuring instrument. Preceding this experiment, the four testees were tested three times daily, that is, every morning, daytime and night, by this flicker fatigue-measuring instrument for ten days, in order to know the type of their most efficient working hours, namely: morning-type, night-type etc, before the experiment was commenced. 1) The illuminance within the integral calculus globe clinic room model was 1950～2300lx between 0～40cm. The average illuminance at the position of 30cm was 2180lx. 2) The illuminance within the clinic room was 1720lx when all circuits are on, 1026lx in D_<65>+Daylight source of light, 1310lx in A source of light+Daylight source of light, 1270lx in A source of light+D_<65>. 3) The average standard deviation of flicker values were: Example A 0.99, Example B 0.95, Example C 1.18, Example D 1.38. Within the integral calculus globe clinic room model, there was no difference in fatigue before and after the operation. 4) The flicker value of one-hour reading within the integral calculus globe clinic room when the source of light was all circuit, D_<65>+Daylight, A Light+D_<65>, was +1.0～-1.2. This shows that 〓 difference is -0.3 and proves little degree of fatigue. Compared to this, when reading is done on an office desk with just one source of light, the value is -0.5～-2.5, which means that the average difference is -1.0. This indicates a strong fatigue when reading is done on an office desk. As a result of this, we may well assume that the integral calculus globe clinic room cause less fatigue. | |||||||
