Lighting Design for Hospitals

The modern hospital has a good lighting system, which can alleviate the bad mood of patients in a bright and comfortable environment, and ensure that medical workers can complete various tasks efficiently and quickly.

Outpatient department

The diagnosis and treatment department is the center of the hospital, so it is necessary to give full play to its functional role in a comfortable environment. Because this part of the practice is in the daytime, for rooms on the first floor that are only illuminated by artificial light, consideration should be given to the balance of illuminance of natural light entering from the gate.

Public hall

The public hall is the central area with the most frequent personnel movements, and is connected to the consultation room, corridor, and stairs. If the public hall is in the form of a building atrium, the gas discharge lamp should be the main choice. The atrium should handle the smooth conversion of natural light and artificial lighting to prevent the illuminance of the corridor around the atrium from being too low, and the light and dark gap causing the visual discomfort.

The installation of lighting fixtures in the shared lobby space with less natural light should consider the convenience of maintenance and maintenance. Small-scale flood lights are installed on the side wall of the hall corridor. Maintenance personnel can reach the lamps by the side of the corridor, which is convenient for maintenance and convenient. Adjust the angle of the flood light to make the light softly and uniformly illuminate the lobby space. The internal and external lighting of service windows such as registration, charges, and tests must be bright, because medical staff and patients or their families need to view and verify the documents and fees handed over.

Public walkway

The public aisle in the ward is different from the outpatient and emergency medical technology building. Inpatients are suitable for a quiet environment, and the lights should be uniform and soft. Therefore, the illuminance is relatively low, generally around 50lx. Recessed warm light fixtures or small compact fluorescent lamps should be used. There is a foot lamp under the door of each ward in the aisle for nurses to use for night inspections, and general night lighting can be turned off.

Each safety aisle of a public walkway should be installed with “safety exit” sign lights above the doorway leading to the outdoor or safety stairs, evacuation sign lights should be installed at the corners of the longer walkways, and the distance between the evacuation sign lights should be equal to or less than 20m.

Consulting Room

The horizontal illuminance and vertical illuminance of the consulting room must meet the doctor’s requirements for observation and writing, and the illuminance should generally be above 300lx. In addition, venetian blinds should be installed in consultation rooms with better natural lighting. The interior layout should also avoid direct sunlight in the summer and important equipment.

The treatment room uses a cold tone, and the light rendering index should be equal to or higher than 80 for light and spirit. In addition, considering that the patient may lie supine on the bed, the design should avoid direct glare in the field of view of the supine patient. For this reason, a reflective narrow-diameter straight tube fluorescent lamp with a shading plate should be used.

Check room

Examination of body parts can be considered as in a general chemistry laboratory. However, when considering the color rendering of the light source, even if the efficiency is low, it should meet the requirements of light color. It is also important to consider how to make patients feel safe and relaxed in the physiological examination room for patients because of the sense of pressure in the place.

Radiation room

Studios related to radiation do not need too high illumination, but require dimming. X-ray room needs 200lx illumination for mechanical maintenance and adjustment. At the perspective stage, 50lx is required to enter and exit the room. You can adjust the red light from 20lx to zero when you see through.

Ward

The lighting of the ward is generally 100-200lx, and care should be taken to prevent the patient lying upward or horizontal from feeling glare. Single or double wards with lighting fixtures on the bedside wall.

When the beds are arranged in two rows like a six-bed room, the lighting fixtures are mostly set in the center of the room. This requires a full study of the position of the patient’s eyes and the light distribution of the lighting fixtures. General lighting fixtures are expected to be dimmable. In addition to general lighting, a bedside lamp should be installed on the patient’s bedside for reading and cooking.

Operating room

The operation department is a long and intense work in a relatively narrow place without a window. Therefore, the operating room lighting must be considered to reduce the fatigue of related personnel. The range from the operating room to the passage of the preparation room generally requires high illuminance, which requires that the lighting fixture has good diffusivity, a cover, a solid structure and no dust.
