Analysis of ward lighting environment and design of comfortable ward lighting

Abstract

Background: and Purpose. With the continuous improvement of people's health consciousness, the traditional hospital lighting and power supply system can no longer meet the needs of people's treatment. A well-designed hospital lighting and power supply system can enable patients to obtain a safe and comfortable treatment environment, which is more conducive to their recovery. Therefore, it is of far-reaching significance to study and design hospital lighting and power supply systems to provide a more advanced, safer and more reliable treatment environment for the majority of medical patients. Methods: In this paper, on-site measurements combined with computer numerical simulation were used to test and analyze the data of ward lighting, and experimental personnel were invited to evaluate and verify the comfort of the lighting. Results: The retrofitted ward lighting not only improved the illuminance and color temperature required for patient life and healthcare workers' examination and care, but also substantially improved the UGR values for patient perspective and experimenters' comfort assessment. Conclusions: The common ward lighting layout lacks in-depth consideration of patient comfort, and the introduction of patient-centered design of medium color temperature and large shading angle of multi-point light sources can greatly improve the ward lighting environment and enhance the visual comfort of patients.
