They proposed the m_DGI as an index to assess the degree of discomfort glare. However, the test lights that cause strong discomfort glare were not examined there. In this study, we conducted a subjective evaluation experiment using seven types of LED streetlights including those of higher luminance in the outer environment similar to the previous study. The results revealed several fi ndings. First, discomfort glare is strongly felt when the positional relationship between the pedestrian and lighting fi xtures is in a certain range; second, light sources with spatially non-uniform luminance distribution cause a strong discomfort glare; third, GR for sports-fi eld lighting is not suited for discomfort glare evaluation of pedestrian zones; and fourth, the relation found in the previous study was confi rmed. In addition, we confi rmed the versatility of m_DGI from weak to strong discomfort glare evaluation. We proposed a new index m_GR calculated using equivalent veiling luminance. Correlation to the discomfort glare evaluation is worse than m_DGI, our data indicate that m_GR is applicable to estimate a degree of discomfort glare in practical situations.","PeriodicalId":35437,"journal":{"name":"Journal of the Illuminating Engineering Institute of Japan (Shomei Gakkai Shi)","volume":"100 1","pages":"449-454"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2150/JIEIJ.100.449","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68757916","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}

However, it can also be a source of light pollution. In wet rice cultivation, light pollution due to exterior illumination results in delayed fl owering (heading), which in turn leads to a reduced yield and to a low-inspection grade at the harvest stage. Therefore, the relationship between a delayed heading period and the light intensity or irradiation period needs to be studied. This study attempts to models the rice growth process in light pollution to propose lighting and cultivation management that will ensure pedestrian safety as much as possible while utilizing countermeasures against light pollution at effective and appropriate times.","PeriodicalId":35437,"journal":{"name":"Journal of the Illuminating Engineering Institute of Japan (Shomei Gakkai Shi)","volume":"100 1","pages":"229-233"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2150/JIEIJ.100.229","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68758205","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}

It is necessary to install appropriate lighting equipment, especially ef fi cient lighting equipment, in tunnels. Light distribution of luminaire is a factor that affects the equipment scale. However, the relationship between light distribution and energy consumption has not yet been clari fi ed. Against this backdrop, we propose a light distribution design method for highly ef fi cient tunnel lighting that reduces energy consumption and a tunnel lighting design method that optimizes the features while ful fi lling lighting performance requirements based on the relationship between the light distribution of tunnel lighting and the illumination characteristics for tunnel luminance (symmetrical lighting method) used as existing tunnel luminance. We evaluated the effects of luminance on the light distribution by simulations in an actual tunnel and con fi rmed the effectiveness of the energy saving.","PeriodicalId":35437,"journal":{"name":"Journal of the Illuminating Engineering Institute of Japan (Shomei Gakkai Shi)","volume":"100 1","pages":"217-223"},"PeriodicalIF":0.0,"publicationDate":"2016-01-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://sci-hub-pdf.com/10.2150/jieij.100.217","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"68757978","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}
