ジャーナル フリーThis paper presents a blind control algorithm taking account of surrounding objects, e.g. surrounding buildings and eaves, which have significant effects on discomfort glare from the window. A subjective experiment was carried out by using windows with automated blinds in the test room. A numerical simulation was carried out to compare the blind control based on PGSV with the conventional one. The results showed a significant effect of the shadow of the surrounding objects on glare sensation. Using this method can reduce the off-set angle (additional slat angle) and encourage the use of daylight.抄録全体を表示PDF形式でダウンロード (2232K) -

ジャーナル フリーWe show the effect of daylighting system and the change in required illuminance on the energy efficiency and quality of indoor lighting environment. Not only the quantity of a daylight illuminant but also the quality should be evaluated to improve daylighting and blind control. The results of experiments show that the further reduction of lighting energy consumption and the reflection of color temperature to the interior light environment can be obtained by lowering the lower limit of modulated light and the required illuminance.抄録全体を表示PDF形式でダウンロード (5240K)

ジャーナル フリーWe developed high-performance electrodes of narrow cold cathode discharge lamp. The discharge characteristics of the electrodes were measured. The electrode used for discharge lamp was a small cylinder type (cup type). The electrode had an inner diameter of 2.6 mm. The MgO film was deposited on the inner wall of the Ni cup by DC sputtering. The cathode voltages of the electrodes both with and without MgO films were simultaneously measured with a high voltage probe connected to a digital oscilloscope when the lamp was operated by a sine-wave power supply under the same discharge condition. The maintained voltage was about 60 % lower for the electrode with the MgO film than the Ni electrode. Furthermore, there was hardly any sputtering in the discharge tube for the electrode with MgO film.抄録全体を表示PDF形式でダウンロード (2039K)
