An Implementation of a User Location-based Lighting Collaboration System
Background/Objectives: This study proposes a user location-based lighting collaboration system that guarantees the target illuminance and uniformity at local position of the user in an indoor space and minimizes energy consumption. Methods/Statistical Analysis: The proposed system is divided into the dynamic cell positioning process and lighting collaboration process. The dynamic cell positioning process finds the specific location of a user based on the RSSI signal intensity of the BLE beacon and smartphone that the user carries. The lighting collaboration process calculates each output of the surrounding lights in consideration of the target illuminance at the user position and then performs dimming control accordingly. Findings: To evaluate the performance of the proposed system, this study includes two control groups - two similar systems - and compares the target illuminance, uniformity, and lighting energy consumption. Control Group A is a system that comprehensively controls all light/light fixture installed in that space while Control Group B divides the space to sub-zones and groups lightings in each zone for controlling. The system performance evaluation result shows that the lighting energy consumption of the proposed system was 1,804W while those of Control Group A and Control Group B were 2,644W and 2,511W, which indicates a savings of as much as 31% and 28%, respectively. In addition, the proposed system satisfied a uniformity requirement as high as 0.8 while maintaining the target illuminance. Application/Improvements: The result indicates that the proposed system had energy saving effect as much as 31% compared to Control Group A and 28% compared to Control Group B.
