娱乐模式下平均水平照度值不达标,估计设计不足(实际功率未达到标定功率或光效、光衰等不达标)
摘要 体育场馆照明设计需要综合斟酌诸多影响要素,比方说照度(包括水平照度和垂直照度)和平均性、频闪、炫光和光源色温及显色指数等,以匹配多种模式下(如彩电转播模式、一般比赛模式等)的照明需求。如照度值和照度均匀性不达标会致使场地明暗不均,影响运动连续性,导致运动员和裁判员判断错误,对观众观察球的连续运动轨迹不利,带来包括摄像不清等问题;频闪不达标则不能满足运动员长时间比赛舒适度要求和慢动作镜头要求,现场检测有明显的50HZ波动,容易造成慢动作图像的明暗抖动;炫光严重时运动员则可能出现短暂性失明;而显色指数与色温不达标会影响观众现场体验感。本课题提出采用现代光测量技术对舟山黄龙体育场馆照明进行实地测量,对其照明效果进行评估。根据测试结果,发现场馆色温与显色指数均满足要求。根据照度,频闪,眩光指数,存在的问题,为体育场馆照明维护和改善提供有益建议。

Testing and Evaluation of Sports Venues lighting
Abstract Many factors should be considered in the design of sports venues, such as illumination (including horizontal illuminance and vertical illuminance) and uniformity, glare and stroboscopic, color temperature and color rendering index, to meet a variety of modes (such as TV retransmission mode, match mode etc.) of lighting needs. The dissatisfaction of illumination intensity and illumination uniformity will lead to uneven ground shade, impact the continuity of the ball’s movement, resulting in athletes and referees’ errors in judgment and continuous motion observation disadvantage, such as unclear photography, to the audience. Meanwhile,the underachievement of stroboscopic can not meet the athletes’ requirements of comfort and slow motion segments in long and continuous matches. It can easily cause the shading of the slow motion image if the field detection has obvious 50HZ fluctuation. Athletes may have temporary blindness under serious glare and non-conformity color temperature and color rendering index can affect live experience. This project proposes the use of modern optical measurement technology to measure the stadium lighting and evaluate its lighting effect. According to the data, we find that the color temperature and color rendering index meet the requirement. Meanwhile, we analyze the data of illuminance, stroboscopic and glare to provide some useful suggestions for lighting maintenance and improvement of gymnasium.

1 绪论
当代体育在人类日常生活中的主要职能和效益愈来愈被人们所认同与正视。体育的内涵是丰富的,体育就包含:“更高、更快、更强”奥林匹克精神的竞技体育,有观赏性且能创造票房价值的市场体育,以及健身强体的群众体育,这三部分组成的体育产业在目前整个经济社会中商机无限。而所有的体育运动及其产业,都与体育建筑息息相关。
