Study of Utilization Factor of Highway Tunnel Luminaire
摘要
Abstract
Utilization factor ( UF ) of luminaire is an important parameter in calculating horizontal illuminance of tunnel road surface in the process of tunnel lighting design or parameters optimization of tunnel lighting, increase of UF is conducive to the average illuminance of road surface. However, UF was usually set as a fixed value or get from UF curve of luminaire, which caused calculation errors. An UF model of tunnel lighting luminaire was made to get the real UF in accordance with light distribution data of adopted luminaire and luminaire installation parameters. Based on the model, the relationships between UF and luminaire installation height, crosswise offset distance and elevation angle were analyzed. A simulation example showed that the UF model is correct, when the UF model is applied to optimization of luminaire installation parameters, more accurate optimized parameters and more energy-saving lighting system can be gotten than that of UF set as a fixed value. The UF model is suitable for calculation of UFs of central luminaire distribution, offset-of-vault luminaire distribution, stagger luminaire distribution and symmetric luminaire distribution.关键词
