Abstract

Interior spaces are majorly shaped by lighting, affecting not only the way in which a space is visually perceived but also the occupant’s well-being. The concept of lighting design and user experience in the context of the built environment has increasingly been a focus in modern interior architecture. Psychological comfort, physiological reactions and perception of space are all influenced by natural and artificial lighting conditions. Natural light is associated with regulation of circadian rhythms, better mood and higher productivity, whereas artificial light can have a positive or negative impact on these outcomes, and this is primarily dependent on the quality of light. Light intensity, colour temperature, distribution, and control systems are just a few examples of the factors that impact how users experience and engage with indoor spaces. A study of the existing research, together with particular cases, allows you to analyse the lighting approach in home, commercial, and institutional interiors. It also covers human-centric lighting systems that dynamically adjust based on user needs. Good lighting design is visually comfortable and spatially enhance interior environments. Lighting and interior finishes, such as materials, colours, and textures, are related to the creation of atmosphere, influence perception and behaviour within a space. Practical guidance on achieving balanced and energy efficient lighting in different environments is to enhance user comfort, spatial quality and sustainable interior design practices. Generally speaking, lighting should not be considered as simply a functional requirement but as a key design tool through which more engaging interior environments can be created. Its integration thoughtfully in the interior can greatly improve the user experience in contemporary design.
