ABSTRACT

Current standards for light environments are based on technical requirements, e.g. luminance, uniformity, and illuminance, and do not necessarily describe all parts of the light experience to ensure visual comfort from a user perspective. Including experience-related requirements would most likely yield better lighting comfort. To do that, new methods for specifying and measuring the user experience are needed. This paper describes a pilot study exploring a new method to analytically assess perceived lighting properties by using a trained human panel and thus make human assessments more objective. The methodology is built on established sensory methods, where the human senses are used in product assessments, traditionally applied within e.g. the food, packaging, and car industries. An analytical panel comprising eight persons fulfilling specific selection criteria were recruited and trained to assess lighting products in a multi-sensory laboratory. The results show that the panelists were able to assess lighting by distinguishing between attributes and products. Significant differences were identified between the different luminaires, both in terms of sensory and physical properties, e.g. readability and glare. Conclusively, analytical sensory methods can be applied to lighting to assess luminaires in a non-subjective way. Physical and sensory attributes do not, however, always co-vary, which shows that data from physical and sensory measuring methods provide complementary information about light quality. This knowledge may in turn be applied in tools supporting the communication between different professions in lighting design and procurement to promote light environments that are both energy efficient and desirable from an end-user perspective.

摘要

当前的光环境标准基于技术要求，例如亮度、均匀性和照度，并不一定描述光体验的所有部分，以确保从用户角度来看视觉舒适度。包括与体验相关的要求很可能会产生更好的照明舒适度。为此，需要用于指定和衡量用户体验的新方法。本文介绍了一项试点研究，该研究探索了一种新方法，通过使用受过训练的人类面板来分析评估感知的照明特性，从而使人类评估更加客观。该方法论建立在既定的感官方法之上，其中人类感官用于产品评估，传统上应用于食品、包装和汽车行业。一个由符合特定选择标准的八人组成的分析小组被招募和培训，以评估多感官实验室中的照明产品。结果表明，小组成员能够通过区分属性和产品来评估照明。不同灯具在感官和物理特性（例如可读性和眩光）方面存在显着差异。最后，分析感官方法可以应用于照明，以非主观方式评估灯具。然而，物理和感官属性并不总是共同变化，这表明来自物理和感官测量方法的数据提供了关于光质量的补充信息。
