Research into energy-saving street lighting is of great significance to city sustainable development and economies, especially given that many countries are now in a period of energy shortage. The control system is critical for energy-saving street lighting, due to its capability to directly change output power. Here, we propose a control system with high intelligence and efficiency, by incorporating improved YOLOv5s with terminal embedded devices and designing a new dimming method. The improved YOLOv5s has more balanced performance in both detection accuracy and detection speed compared to other state-of-the-art detection models, and achieved the highest cognition recall of 67.94%, precision of 81.28%, 74.53%AP50, and frames per second (FPS) of 59 in the DAIR-V2X dataset. The proposed method achieves highly complete and intelligent dimming control based on the prediction labels of the improved YOLOv5s, and a high energy-saving efficiency was achieved during a two week-long lighting experiment. Furthermore, this system can also contribute to the construction of the Internet of Things, smart cities, and urban security. The proposed control system here offered a novel, high-performance, adaptable, and economical solution to road lighting.<\/jats:p>","DOI":"10.3390\/computation11030066","type":"journal-article","created":{"date-parts":[[2023,3,21]],"date-time":"2023-03-21T06:56:48Z","timestamp":1679381808000},"page":"66","update-policy":"https:\/\/doi.org\/10.3390\/mdpi_crossmark_policy","source":"Crossref","is-referenced-by-count":7,"title":["An Energy-Saving Road-Lighting Control System Based on Improved YOLOv5s"],"prefix":"10.3390","volume":"11","author":[{"ORCID":"https:\/\/orcid.org\/0000-0003-4965-135X","authenticated-orcid":false,"given":"Ren","family":"Tang","sequence":"first","affiliation":[{"name":"Research Institute of Photonics, Dalian Polytechnic University, Dalian 116039, China"}]},{"given":"Chaoyang","family":"Zhang","sequence":"additional","affiliation":[{"name":"Research Institute of Photonics, Dalian Polytechnic University, Dalian 116039, China"}]},{"given":"Kai","family":"Tang","sequence":"additional","affiliation":[{"name":"School of Mechanical Engineering, Hefei University of Technology, Hefei 230002, China"}]},{"given":"Xiaoyang","family":"He","sequence":"additional","affiliation":[{"name":"Research Institute of Photonics, Dalian Polytechnic University, Dalian 116039, China"}]},{"given":"Qipeng","family":"He","sequence":"additional","affiliation":[{"name":"Guizhou Zhifu Optical Valley Investment Management Co., Ltd., Bijie 551799, China"}]}],"member":"1968","published-online":{"date-parts":[[2023,3,21]]},"reference":[{"key":"ref_1","doi-asserted-by":"crossref","unstructured":"Bachanek, K.H., Tundys, B., Wi\u015bniewski, T., Puzio, E., and Marou\u0161kov\u00e1, A.
