目前公认的观点是，一般照明实践的基本目的是实现视觉任务的执行，但经过检查发现缺乏实质内容。建议根据照明环境的视觉体验重新定义照明的目的，并为此提出了两个标准，这两个标准都与传统实践有很大的不同。第一个根据周围房间表面反射光的密度来评估活动的照明是否充足，第二个涉及灯具光通量如何引导到选定的目标表面。总而言之，这些标准为一般实践的照明装置设计提供了一种全新的方法。
The currently accepted notion that the basic purpose of general lighting practice is to enable performance of visual tasks is examined and found to be lacking in substance. It is proposed that the purpose of lighting should be redefined in terms of the visual experience of illuminated surroundings, and two criteria are proposed for this purpose, both of which represent significant departures from conventional practice. The first assesses the adequacy of illumination for an activity in terms of the density of reflected light from surrounding room surfaces and the second is concerned with how the luminaire luminous flux is directed onto selected target surfaces. Taken together, these criteria offer a quite new approach for designing lighting installations for general practice.
