This article mainly studies the effects of different spectrum, wavelength and time changes in the light source that adjust the exposure during sleep on the quality of sleep, and then obtains a useful formula for sleep. Since the previous experiment mainly focused on the prototype of the light source, it is not easy to use. Therefore, this research aims to expand the convenience of future use and confirm whether the backplane light source of the smart mobile device can match the results of the previous long-term research. Develop an APP(Application) that uses dynamic sleep light to apply to smart mobile devices. This study mainly uses the dynamic light color temperature and time change of the previous long-term research as the experimental parameter settings, and the results of a small sample trend study found that the effect of the previous experiment is highly correlated with each other, so the number of samples in this experiment is still increasing. The team judges that the future results should be highly consistent with the previous results.","PeriodicalId":405944,"journal":{"name":"2020 Fifth Junior Conference on Lighting (Lighting)","volume":"7 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"130004661","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Both events are “in phase” – the higher sun irradiation, the higher the power consumption. That fact makes implementation of photovoltaic generators very efficient and eliminates the need of power storage. Direct power generation is just one of the components that can increase the energy efficiency of road tunnels. The paper discusses a complex of measures causing significant reduction of power consumption and overall expenses of road tunnels.","PeriodicalId":405944,"journal":{"name":"2020 Fifth Junior Conference on Lighting (Lighting)","volume":"27 1","pages":"0"},"PeriodicalIF":0.0,"publicationDate":"2020-09-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"114184031","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
