摘　　要：灯具距高比是室内一般照明用灯具的1个基础性光度学参数。对照明设计师来说,没有距高比的数据就缺少了灯具光度特性的1个关键参数,难以估算室内照明的灯具数量和安装间距。安装距离过小或过大,将造成灯具数量过多、照度太高的浪费,或照度太低、不能得到均匀的照明。室内一般照明用的灯具,如筒灯、格栅灯具、平板灯具等,应提供灯具距高比参数值。Luminaire spacing-to-mounting-height ratio is the basic photometric characteristic for interior generallighting luminaries. It is difficult to calculate amount of luminaries and mounting spacing if illumination designers don＇t get spacing-to-mounting-height ratio of luminaries that is the key photometric parameter. Too small or too big mounting spacing will induce too many luminaries to be laid and illuminance waste, or too low illuminace and non- uniformly illumination. Manufacturers of interior general-lighting luminaires such as downlights, troffer lights and panel lights, should give the spacing-to-mounting-height ratio.
