Many studies on the effects of LED on living organisms have been performed recently thanks to the ease and precision with which the power and wavelength of the LED can be regulated. To investigate the effects of LED irradiation on Drosophila activity, we monitored the locomotive activity of Drosophila for six days continuously. The data showed that wild-type flies behave similarly under fluorescent light, incandescent bulb, and white LED irradiation, which is equivalent to the intensity of an incandescent bulb. We next investigated the effects of red, blue, and yellow-green LED irradiation under same intensity as white LED on the locomotive activity of a wild-type fly and a Drosophila model of autism spectrum disorder (ASD). The results showed that the amount of locomotive activity in the wild-type flies with red LED irradiation was significantly increased throughout the day (excluding morning peaks) while that with blue LED irradiation was decreased in evening peaks and at nighttime. Yellow-green LED irradiation increased the locomotive activity during the midday siesta but decreased the activity of the morning and evening peaks.It is known that the rugose (rg) mutant, the Drosophila homolog of human Neurobeachin, shows locomotive hyperactivity. In our study, the red LED irradiation did not affect the locomotive activity of the rg mutant at all. Taken together with the effects of red LED irradiation to the wild-type, it seems that red LED irradiation enhances the neural circuit to positively regulate the locomotive activity, and rg functions in the neuronal cells by negatively regulating the neural circuit enhanced by red LED irradiation. Thus, the neuronal cells expressing the rg gene appear to play an important role for the regulation of activity during the midday siesta and while sleeping at night. In contrast, irradiation with yellow-green and blue LED to the rg mutant had similar effects to those of the wild-type. This demonstrates that irradiation with yellow-green and blue LED negatively regulates the locomotive activity through the neural circuit not related to rg, or downstream of the neural circuit actively regulated by red LED irradiation.

The Division of Illumination Promotion took over the lighting promotion activities previously conducted by the Illumination Promoting Division of the IEIJ. Its main responsibilities are presenting the Lighting Promotion Award, carrying out joint events for "Akari No Hi (Day of Illumination)" and issuing of various publications such as the "New Lighting Classroom Series". In the future, in addition to coordination with branches, we want to consider activities connected with other divisions and sub-committees.

In the saury fishing, incandescent lamps are usually used for a fishing light. However, there are problems of the conventional fishing lights using incandescent lamps . First, electric power consumption is large. And the incandescent lamps are very inefficient, because much infrared light is included. Furthermore, life time is short and there is a problem of a lot of heat generation. Therefore, we attempted the development of highly efficient fishing lights using LEDs for saury fishing. We designed the combination of various LEDs for a fishing light, based on the spectral luminous efficacy of a Pacific saury. We performed the saury-fishing experiments by using the LED fishing lights, and comparable catch of Pacific saury was achieved by approximately 55% electric power by using both LED poles and incandescent lamp poles. Moreover, we attempted the development of LED fishing lights for squid, and it was found that comparable catch was achieved by lower electric power than that of conventional fishing lights.

網膜の視細胞には蛋白の他多量の類脂肪, 殊に燐脂體が多量に含まれて居り, 光の作用で減少する. 網膜から光によつて燐酸や稍複雑な含窒素化合物やヒヨリン等が遊離する. 是等の現象は盲にした網膜では起こらない. 從て視質は感光性の強い燐脂體の一種ではないかと考へられる.視紅は分解してビタミンAを出すから一種のカロチノイド系の色素と思はれ, 視質に結合して増感作用を營むものと思はれる. 是等の物質の光分解後, それを再生せしむるためのエネルギーは, 網膜内で特に旺盛な解糖作用によつて供給せられるやうである.

NIIGATA MONOLITH is a comprehensive bridal facility newly built in Niigata prefecture. The ceiling of the banquet room has an inclination of CH:5,700mm to CH:7,300mm, and approximately one thousand transparent acrylic tubes are laid on the ceiling. The challenge was to reduce the running costs including maintenance fees while keeping the ceiling high. HIMEJI MONOLITH is a comprehensive bridal facility built based on an about 80 year-old house by renovating the interior as a guest house. The minimum LED spotlights are used to illuminate the exterior of the building, which received a designation of the Important Building for Landscape of Himeji-shi, Hyogo prefecture.
