Empirical research of using digital addressing LED energy-saving lighting control system — The case of underground parking lot: Preparation of papers in two-column format for ISNE 2016

A conventional lamp may tend to be of high power consumption because aging and the lamp cover discolors. According to the study, after the conventional lamp is replaced by the proposed lamp, the proposed lamp can save about 65% of the power consumption. On the other hand, the study finds out the best luminous efficiency of the main body by the addressable lamp control method, and we calculate the possible illumination intensity via the lighting simulation software so as to check whether the proposed lamp conforms to the illumination standards and the safety illumination standards. After the whole simulation is finished, we actually replace the conventional lamp by the proposed lamp, and then practically test the total power consumption efficiency during two weeks. Afterward, we find that the power saving rate can be up to 77.5%. In other words, in addition to the original saved efficiency by using proposed lamps, the control system can further create 12.5% power saving rate, and provide an environment with good light quality and safe usage site. The study adopts the currently available T5 lamp with high luminous efficiency for users to conveniently replace the lamp by themselves, which can solve the matching problem that the lighting control systems have. Therefore, the study provides a best solution for public constructions of lamp replacement.
