A Study of Lightings for Elder with Dementia

I This study sought to obtain empirical evidence for the impact of through the auxiliary healthy light, delaying disease Senile Dementia and change periodicity of the disease. Through the research, we designed 10 groups of healthy light sources to find out the best parameter formula. The data were elicited using physiological measurement (including sleep actigraphs monitoring at night, body temperature and Oral Fluid Test. Eight subjects (4 males and 4 females) used a quasi-experimental which had been design to assess the effects of were used as indicators to explore the non-subjective assessment of lighting sources on the index, and The center for experimental studies expression scale (CES-D) was used as the subjective assessment of the subjects. The results of this study showed that sleep actigraphs users among Efficiency, Latency and the Number of Awakenings had been attained the best formulation performance at 5000k/6000lx. Besides, (CES-D) is displayed in the oral fluid test high illumination and high correlated color temperature(CCT) even better performance.
