Human-centric lighting

: a lighting concept which influences our well-being : exploring the relationship between awareness and willingness to pay for health-conscious consumers

Abstract

The results of scientific research in recent years clearly show that light not only helps people to see but also has a great influence on their well-being (Stephan & Heike, 2016). Lighting concepts are usually set to a specific light level with constant luminous intensity and correlated colour temperatures, which is not compatible with people's circadian rhythms. If people are not regularly exposed to dynamic lighting, this can lead to a disruption of the circadian rhythm and thus to health problems. Lighting concepts that focus on the well-being of people are referred to as Human-Centric-Lighting (HCL). These concepts offer the possibility to design lighting holistically and to better adapt it to the circadian rhythm of people. The aim of this scientific work is to understand consumers' awareness and willingness to pay for HCL concepts, as well as their perception of how these products can influence their well-being.In doing so, prerequisites for well-being in connection with the HCL lighting concept are to be identified to support companies and end consumers with recommendations for action.The study follows a mixed-methods approach, consisting of 6 in-depth interviews and an online questionnaire, which yielded 99 valid responses.From the analysis, it can be concluded that socio-demographic factors such as age play a central role in the willingness to pay for Human-Centric Lighting. However, health-oriented people also have a positive attitude towards the lighting concept for promoting well-being, provided they are aware of this lighting concept.
