Daylighting Control System for LED Based Energy-Efficient Lighting Systems

Abstract

The proposed system presents a simulation environment and daylighting control approach to achieve energy-efficient lighting system and providing desired lighting levels at the purpose points. The lighting system procedure is based on a self-tuning multivariable controller, which controls the illuminance levels such as maximum or minimum at user-defined set-points, while reducing the   energy consumption as compared to the traditional lighting system. Now a day saving energy has become one of the most significant points. Particularly, a light account for a great part of the total energy consumption. Now a day market can be introduced various light control systems because the currently installed lighting systems are old and energy-inefficient. However, due to structural limitations, the existing light control systems cannot be successfully involved to home and office buildings. Hence, recommends of new intelligent household LED lighting system considering energy productivity and user comfort. The recommended LED lighting system can autonomously adjust the minimum light intensity value to enhance both energy productivity and user comfort. The recommended LED lighting system decreases total power consumption. The technology of Power over Ethernet can take sufficient electricity to LED lighting system. Depending on the understanding knowledge of the current illumination and the whole persons in a room, the system can automatically distinguish and utilize a predefined brightness. Therefore, it overcomes the limitations of a traditional light control system. At the same time system can transfers DC power and data through Ethernet, reduce the power adapter failure which caused by data network failure and promotes the application of the low power network equipment.
