Light is a fundamental part of life. Light gives us the natural rhythm of day and night, determines how we see things, and brings our world to life. Accordingly, it has a major impact on our sense of well-being, our emotions and our functioning. The notion that a well-balanced and attractive environment is of major importance to patients’ health is not new. This research comes in an attempt to study the lighting design for hospitals and its impact on patients’ well-being (visual, biological and psychological) which can promote patient recovery. The research also seeks to study the impact of illuminance level, correlated color temperature (CT), color render index (CRI) and lighting control on lighting design. In addition, the research display the lighting design in Al Shifa hospital patients’ room in surgery, internal medicine and heart care departments. In this context, the research assumes that the natural and artificial lighting have a significant impact on patients’ well-being and the illuminance level, color temperature (CT), color render index (CRI) and lighting control are the most important characteristics of light to be considered. The research is carried out using Post-Occupancy Evaluation (POE) tool, which used mixed method that depend on quantitative and qualitative data. Questionnaire was used to collect qualitative data and analyze it, and the number of participants who fill the questionnaire were 30 inpatient, amd those participants are distributed on 21 patients' room, during the application of the questionnaire measurements of lighting intensity inside patients room were taken by using iPad app called Luxmeter. The results indicate that type of existed lighting (Fluorescent) in surgery, internal medicine and heart care departments in Al-shifa’ hospital was suitable, whereas Ra= 74, and color of lighting is daylight which fits with patients room, but there is a problem in lighting design, which is represented in the absence of variety in colors of lighting and controlling method in colors of lighting. In addition, it indicate that good design includes the availability of dimmed lights during sleeping time, which increases public satisfaction level about lighting and increases the biological effects on patients’ well-being inside the rooms during sleeping, healthy sleeping can help to improve the patients’ well-being by helping to secrete the human body melatonin hormone in darkness. Good design according to design consideration, which includes design quality that is specialized in lighting intensity, color temperature, color render index (CRI) and control system lead to improve the well-being of patients, which increases the level of public satisfaction, visual comfort, improves the feeling of the place, mood, and psychological comfort. Therefore, the research recommends using high quality lighting types with high Ra, coloring temperature (CT) of lighting similar to daylight such as neutral white. In addition, use lighting that include automatic control in healthcare facilities. In addition, use several illumination for the patients’ that serve every patient individually, and must provide bedside lighting fixtures, high intensity lighting above patients’ beds, and patient control of these lighting. Moreover, providing dimmed lights for patients’ at sleeping time.
