Subjective Comprehensive Evaluation of LED Light Environment in Confined Space

Based on the research results of the subjective influence of existing lighting environment on people, this paper establishes an experimental model of LED light environment in confined space and determines the subjective evaluation index of LED light environment affecting confined space as pleasant, spacious, privacy, glare uncomfortable, clear, relaxed, spatial lighting coordination, color authenticity, three-dimensional shape, light and dark contrast. From the weight of these 10 subjective evaluation indicators, the senses of pleasure and relaxation have a greater impact on the overall satisfaction of the lighting environment. The extensional theory is used to determine the subjective comprehensive evaluation function, and its feasibility is verified. It lays a foundation for the subsequent establishment of a comprehensive evaluation method for LED light environment quality in confined space and creates conditions.
