As a place dedicated to saving lives and helping the wounded, the hospital needs to create a spacious and comfortable atmosphere, a clean and quiet environment, so as to give full play to the functions of the hospital, which will directly or indirectly affect medical health.
Therefore, hospital lighting design should not only meet the requirements of medical technology, give full play to the function of hospital medical equipment, and effectively provide medical services, but also consider creating a quiet and harmonious lighting environment for patients, which is beneficial to the treatment and rehabilitation of patients.
Since the hospital must ensure 24-hour normal lighting, there are no holidays throughout the year, and the lighting requirements are extremely high, the LED side is easy to meet the almost demanding lighting requirements of the hospital, and its energy-saving transformation potential is quite huge.
Hospital lighting is highly functional, clean and precise. Lighting design should understand the nature of its work and lighting requirements, and adopt various measures to meet the requirements of the medical sector. I know that hospital buildings include patient rooms, outpatient clinics, medical technology and various medical service facilities, and the lighting requirements are also different.
Lighting fixtures are selected according to the different functions of various departments of the hospital, medical staff in many cases must observe and judge the skin color appearance of patients to make correct diagnosis, therefore, in addition to ensuring 24-hour normal lighting, examination room lighting should meet the requirements of low color temperature and high color rendering.
For example, hallway lighting uses easy-to-use daylight fixtures to promote a safe mood for patients: emergency room lighting is basically the same as the requirements of the examination room, while paying full attention to the color rendering of the light source and meeting the needs of local minor surgical lighting. At the same time, in any occasion, the hospital should pay special attention to limit glare.
In fact, color plays an important psychotherapeutic role for patients, light sources and architectural decoration skillfully coordinated, rational use of natural light, will help to create an atmosphere and environment that promotes the recovery of patients.
Color is more important for medical staff, as mentioned earlier, the light source needs to correctly reflect the patient’s skin color, and meet the requirements of surgery and treatment.
The medical departments with different functions also have different requirements for lighting, and the departments such as treatment rooms, instrument examination rooms, operating rooms, CU (monitoring centers) must consider the color rendering of the light source, and should choose a light source with high color rendering.
In addition, hospital environmental lighting in different regions, the requirements for the color temperature of the light source are also different, hospitals in colder climates should use warm white (low color temperature) light source, which can bring a warm feeling to the environment. Hospitals in the tropics should use a cool white (high color temperature) light source to bring a cool feeling to the environment. The lighting source should choose a light source with high efficiency and energy saving, high light efficiency and good color rendering.
How should the design of hospital lighting be handled? The purpose of hospital lighting is to give full play to the function of the hospital, directly or indirectly to the medical service, so it is necessary to understand the function of each part of the hospital lighting.
What distinguishes hospital lighting from other architectural lighting
This article says that when designing hospital lighting, the differences in other architectural lighting should be considered.
1.the hospital is a comprehensive place for different groups of people to 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 300x illumination, and the hospital corridor in the middle of the night only needs a lux.
2.The hospital is not only a place for medical staff to work, but also a place for patients to play, rest and live. Therefore, lighting design should consider both the needs of medical personnel and the needs of patients. For the ward department, the reception lounge, and relatively speaking, the choice of spacious and comfortable atmosphere is the first choice for lighting design.
3.Many places in the hospital, such as: reception rooms, toilets, etc., are 24-hour continuous work. Especially the reception room, which should be adapted to different groups of people working in different periods of time within 24 hours. The needs of life, lighting design should be considered according to different situations.
4.Modern hospitals have a large number of special places, such as: security departments, modern equipment, lighting equipment selection should be able to meet the lighting requirements of these special areas.
About the design process of hospital lighting
Usually hospital lighting design is carried out according to the following flow chart:
- 1.Function analysis
- 2.Determine the beadness of each lighting device according to the environment
- 3.Determine the lighting method
- 4.Determine the lighting standard
- 5.Determine the lighting quality
- 6.Light source selection
- 7.Lamp selection
- 8.Illuminance calculation
- 10.Determine the electrical control switch mode
Lighting methods used in hospitals
Different places in hospitals have different requirements for lighting, and the lighting requirements of the same place are different in different time periods, even if in the same place, in the same time period due to the use requirements of different people, the way of lighting will still be different.
