Medical lighting: 3. Lighting creates a pleasant and pleasant visit, working environment

Physiologically, warm light stimulates the endocrine function of the accessory kidney gland/thymus/thyroid, excitatory nerves, suitable for rehabilitation patients; while cool color light can stimulate the pituitary gland, calming the nerves, and calming chronic patients. Color plays an important psychological treatment role for the patient. The light source and the architectural decoration are skillfully matched, and the rational use of natural light will help create an atmosphere and environment that promotes the recovery of the patient. The environmental lighting of hospitals in different regions also has different requirements for the color temperature of light sources. Hospitals with colder climates should adopt warm white (low color temperature) light sources to bring warmth to the environment. Hospitals in the tropics should use a cool white (high color temperature) light source to give the environment a cool feeling. Therefore, the visual environment is both a physiological and a psychological requirement, and it must be judged before the correct lighting design can be carried out.

The comfortable lighting environment can also alleviate the mental and physical fatigue caused by long-term, high-intensity work, improve work efficiency and work quality, and thus better serve the hospital. Lighting should give a bright, clean light environment. Indirect lighting can be used in areas with ceilings to avoid direct lighting. The overall space uses a high color temperature and high illumination environment. For those who often write at the desk, it is best to have a desk lamp on the desk as a local lighting desk lamp. In addition, night work lights should be placed on the upper or side wall of the nursing workbench.

The lighting system of the ward must comprehensively consider the lighting requirements of different people in different time periods, and at the same time take into account the principle that the lighting layout is as simple and economic as possible. Nurses, doctors, and logistics service personnel need different lighting in their respective work in the ward. The patient must be undisturbed, and the patient also needs his own life lighting. In lighting applications, remember that the patient's normal field of vision is mainly concentrated on the ceiling. The ward lighting is a hybrid lighting, which is general lighting, reading lighting, detecting lighting and An organic combination of night lighting.

(3) Set the local reading lighting, the way should be one bed and one light, the lamp is generally installed above the bedside of the patient. If there is a bed-to-bed phenomenon in the ward, it is not advisable to use an adjustable bedside lamp, or the angle of the bedside lamp must be strictly limited to prevent the patient from seeing the light source of the bed and generating glare.

(4) The ambient light of the hospital should not be installed directly above the hospital bed to avoid glare to the patient.

(5) Lamps for pediatrics and elderly wards should be selected for lamps that are suitable for children's psychological characteristics, and the illumination should be appropriately higher.

A good environment for visiting, a comfortable, pleasant and warm atmosphere is the focus of lighting. The use of high color rendering light fixtures can make the patient's look look healthier. Based on the particularity of the ward, the visiting environment should emphasize vertical illumination, and the overall spatial illumination is relatively high. Conversely, lower illumination will easily make the patient depressed. It is used for reading the bedside local illumination.
