Hospital lighting has high functionality, cleanliness and precision. When designing lighting, we should understand its working nature and lighting requirements, and adopt various measures to meet the requirements of medical departments. I know that the buildings of the hospital include ward, outpatient, medical technology and various medical service facilities, and the requirements for lighting are also different.

       Lighting lamps are selected according to the different functions of various departments in the hospital. In many cases, medical staff must observe and judge the skin color and appearance of patients for correct diagnosis. Therefore, in addition to ensuring 24-hour normal lighting, the lighting of examination room should meet the requirements of low color temperature and high color rendering. For example, the foyer lighting uses simple daylight lighting lamps to promote the patient‘s safe mood; At the same time, we should pay full attention to the color rendering of the light source and meet the needs of local small surgery lighting. At the same time, hospitals should pay special attention to limiting glare in any situation.

       In fact, color plays an important role in psychological treatment of patients. The ingenious combination of light source and architectural decoration and the rational use of natural light will help to create an atmosphere and environment for patients to recover. The color is more important for medical staff. As mentioned above, the light source needs to correctly reflect the skin color of patients and meet the requirements of surgery and treatment. The medical departments with different functions also have different requirements for lighting. For the diagnosis and treatment room, instrument examination room, operating room, ICU (monitoring center) and other departments, the color rendering of light source must be considered, and the light source with high color rendering should be selected. In addition, different areas of the hospital environment lighting, the requirements of light source color temperature are also different, the cold climate of the hospital should use warm white (low color temperature) light source, can bring a warm feeling to the environment. The hospitals in tropical areas should use cold white (high color temperature) light source, which can bring cool feeling to the environment. The lighting source should be of high efficiency, energy saving, high luminous efficiency and good color rendering.

       How to deal with the design of hospital lighting? The purpose of hospital lighting is to give full play to the function of the hospital, directly or indirectly to the medical service, so we must understand the function of each part of the hospital lighting.

       About the design of hospital lighting:

In the design of hospital lighting, we should consider the differences of other building lighting.

1. A hospital is a comprehensive place where different groups of people move in different places according to different purposes, and the requirements for lighting are different. For example, the hospital lobby operating in a clean and sterile environment requires 300 lux of illumination, and the hospital corridor at night only needs one lux.

2. Hospital is not only a place for medical staff to work, but also a place for patients to play, rest and live. Therefore, the lighting design should consider not only the needs of medical staff, but also the needs of patients. For the ward of ward department, the rest room of reception, relatively speaking, the choice of spacious and comfortable atmosphere is the key of lighting design.

3. Many places in the hospital, such as reception room and toilet, work 24 hours continuously. Especially in the reception room, we should adapt to different people working in different periods within 24 hours. According to the needs of life, lighting design should be considered according to different situations.

4. Modern hospital has a large number of special places, such as security department and modern equipment. The selection of lighting equipment should meet the lighting requirements of these special areas.
