国家游泳中心冰壶场地光环境提升与照明节能关键技术研究

Study on Key Technology of Lighting Environment Improvement and Lighting Energy-saving for the Curling Venue of National Aquatics Center

国家游泳中心将作为冬奥会冰壶比赛场地,实现从“水立方”到“冰立方”的转变。本文以国家游泳中心为研究对象,利用计算机模拟与现场实验相结合的研究方法,通过多方案优化比选,并严格控制直接和反射眩光,采用智能控制与恒流明等技术,在满足超高清转播对光环境要求的前提下,实现了冰壶场地光环境与能效的双提升。通过优化,最终方案采用290套大功率LED灯具,满足了冰水双模式的使用需求。实测表明,在满足各项光环境指标的同时,照明节能率达到60%以上。对于冬奥场馆等高级别赛事的体育照明设计及应用具有重要的指导意义。

The National Aquatics Center(NAC) will be used as a curling venue for the Winter Olympics, transforming from a "water Cube" to an "ice cube". This paper, with NAC as the research object, and combining computer simulation and field experiment, conducted multi-scheme optimization, and strictly controlled direct and reflected glare. Through intelligent control and constant lumen technology, both the light environment and energy efficiency were improved while meeting the requirements for Ultra-high-definition broadcasting. Through optimization, the final solution used 290 sets of high-power LED lamps, meeting the requirements for both ice and water sports venues. The test results show that the lighting energy saving rate can reach over 60% while satisfying the various light environment indexes. The result of this paper is of great guiding significance to the design and application of sports lighting for venues of Winter Olympics and other high-level events.
