碩士 === 實踐大學 === 工業產品設計學系碩士班 === 101 === Ever since the rapid development of technology, the pace of life has been accelerated; consequently, people’s circadian rhythm may have been changed irregularly due to various possible factors. Accordingly, one of the modern civilization sequelae, insomnia disorders, has been introduced to modern life. Cataletto (2012) pointed out approximately seven to ten percent of patients have the Delayed Sleep Phase Syndrome (DSPS) in the United States, based on the solid data that was collected from the people who have sleep disorders in long-term circumstances. The term DSPS, also known as Circadian Rhythm Disorder, has been applied to situations when the biological clock and life clock has diverged. In medical research of light therapy, Czeisler (1987) verified that light was a key to reset the body’s biological clock each day. Thus, this research aims to examine how the design concept of home lighting could have the effect of relieving DSPS. Three main research areas, Insomnia Disorders, Light Therapy, and Light Emitting Diode (LED), will be discussed and analyzed in the literature review, and related questions will be answered in the research method section. For this study, the case study and in-depth interview were used; furthermore, three experts from the fields of Sleep Medicine, Lighting Design, and Light and Health respectively were interviewed. From Case Study 1, hypnosis for curing insomnia disorders is a classic prescription according to an interview with Dr. Lu1; however, the minority of people is still skeptical of hypnosis. Thus, provided that Light Therapy could improve the quality of sleeping, where the market would be. As for Case Study 2, Lighting Design includes three main elements which are the coverage of lighting, users, and situations. Only when the three main elements for light designing can be distinguished clearly, the highest standard of Lighting Design can be achieved, according to an interview with Mr. Pickelein2. With regard to Case Study 3 and the interview with Dr. Wojtysiak3, the research from OSRAM has verified that the effective parameter of light could improve the quality of sleeping. Thus, this research is based on suggestions which are from professional consultants in order to study Home Lighting Design. Moreover, the regulations of using light in daily life are established according to the result of this study. In sum, two main contributions from this study are as follows: (1) Attempts to organize the specification of lighting design and sources for relieving DSPS, and expects to apply these into home environments. (2) Provides two sets of bathroom mirrors with lighting designed as references according to the specification. Moreover, this shows promise for adjusting or adapting people’s circadian rhythm in their daily life without affecting their lifestyle, by using home lighting concepts and improving people’s life quality.
