Lighting for Hospitals

Ward lighting should be designed to avoid glare, especially where patients' vision is restricted to the ceiling and medical staff.

Sufficient lighting for daily activities in wards, using indirect lighting from bed-head, preferably. Illuminance must range between 100-200 lux at bedhead luminaires.

Illumination for reading/working at beds. Illuminance should be between 100-300 lux across the bed's width.

Supplementary light for examination/treatment, if appropriate rooms are not available. Illumination above 1000 lux and suitable colour rendering are required.

Minimum lighting for navigation in dark hours, with 1.0 lux illuminance at ground level. Securely screened to prevent disturbance or discomfort.

Lighting for patient observation at night, 5-20 lux illumination confined to the bed area. Light switch accessible only by staff.

Corridor lighting should match adjacent room lighting, enabling smooth transitions and providing variable night-time light levels.

Luminaire brightness shouldn't exceed 350 cd/m2, both for patients and staff.

Measure of light intensity at a surface.

Heat from lights should be minimized to ensure patient comfort and safety.

Lighting needs vary by hospital area and user (patients, doctors, nurses, etc.), prioritizing medical staff needs in some cases, and patient comfort in others.

Light color, both emitted by the source and reflected, is crucial. Good lighting aids treatment/examination, and contributes toward patient recovery by creating a friendly atmosphere.

Areas with radiation-sensitive electronics need interference-free lighting.

Essential in all internal hospital traffic areas, exits, and areas where lack of lighting endangers safety.

Hospital ward lighting must consider patient reading, handiwork, rest, and movement, as well as medical & cleaning staff needs.

Choosing the correct fluorescent lamp colour is essential in wards, considering the location's climate and the need for medical examinations.

Suitable for wards in colder climates where a more homely atmosphere is desired. (Colour 83)

Suitable for tropical wards where a comforting atmosphere is desired.(Colour 84)

These higher-color-rendering lamps are preferred for wards where medical examinations demand better color visibility. (93 & 94)

Hospital wards must consider patients abilities to read, work, rest and navigate the ward safely at all times.

Corridors should have bright lighting on the wall opposite room entrances to help people adjust their vision when moving between lit and unlit areas.

Lighting along corridors should be arranged unevenly to avoid discomfort for patients being transported on trolleys.

Corridors should have 200-300 lux during the day and reduced to 5-10 lux (open to bed-bays) or 10-50 lux (other corridors) at night.

Examination rooms should have both general lighting (500-1000 lux) and local lighting to accommodate different tasks, with matched colour temperatures.

Operating theatres need a balance between bright, shadow-free lighting on the operating table and general illumination (around 1000 lux) for the rest of the room.

General lighting in the operating theatre should use fluorescent lamps with a color temperature of around 4000 K and good colour rendering.

The lighting in other rooms within the operating theatre suite (changing rooms, scrub room, etc.) should be at least 50% as bright as the general theatre lighting.

Lighting fixtures should be designed to minimize heat output to ensure patient comfort and safety.

Lighting in this room must be adjustable for various tasks, allowing rapid changes for emergencies. General illumination ranges from 300 lux down to nearly zero.

TL' colour 84 or 94 is preferred for intensive care lighting. Supplementary lights are needed for examinations and treatments.

Lighting in this room depends on the type of x-ray exam. Normal x-ray procedures require no special lighting, while image intensifiers or television systems require a dimmer light of 10-30 lux.

Direct observation of the x-ray screen involves having orientation lighting of up to 10 lux, while patient positioning and cleaning require a dimmer-controlled general lighting of 100 lux.

X-ray rooms need localized lighting for tasks such as giving injections.

Adding decorative lighting, such as a wall luminaire, can create a more pleasant and relaxing environment in an x-ray room.

Hospitals have many rooms beyond wards and intensive care, such as laboratories, offices, lecture theatres, and kitchens. Each room type requires appropriate lighting for its function.

Lighting for rooms like laboratories, offices, lecture theatres, and kitchens is the same as for similar spaces in other buildings.

Hospitals also have service and communication areas that require specific lighting.

Lighting design in hospitals should consider patient comfort by creating a similar atmosphere with ward rooms in the intensive care unit.

Lighting requirements in hospitals vary depending on the area and user (patients, doctors, nurses, cleaners). In some areas, medical staff needs are paramount, while in others, patient comfort is prioritized.

Color is essential for hospital lighting, both from the light source and reflected surfaces. Proper color helps with medical treatment and examinations, and can also contribute to a more welcoming atmosphere, promoting patient recovery.

Hospital ward lighting must cater to both patients and staff. Patients need enough light to read, work, rest, and move safely, while staff need suitable lighting for their tasks.

The color of fluorescent lamps in wards is chosen carefully, considering the hospital's climate and the need for medical examinations. Warmer white is ideal for colder climates, while cool-white is better for tropical locations.

For medical examinations, higher color rendering lamps (93 & 94) are preferred as they make colors more accurate, allowing for more precise diagnosis.

Emergency lighting is a vital safety feature in hospitals, installed in all internal traffic areas, exits, and any location where a lack of light would endanger life.

Areas in hospitals with sensitive electronic equipment require lighting that does not interfere with their operation, avoiding disruptions to critical medical devices.

Operating theatres require a balance between bright, shadow-free lighting on the operating table and general illumination (around 1000 lux) for the rest of the room, ensuring a clear, well-lit surgical environment.

Ward lighting aims to provide sufficient illumination for medical procedures and daily activities, while ensuring patient comfort and avoiding glare, especially for patients with limited field of vision.

Provides focused illumination for reading, handiwork, or other tasks at the bed, achieving 100-300 lux.

Night lighting ensures minimal illumination for nurses and patients to navigate safely during dark hours, with 1.0 lux at floor level.

Corridor lighting should match the adjacent room's lighting to create a smooth transition for patients and staff, often requiring reduced illuminance at night.

The brightness of light fixtures should be minimized, not exceeding 350 cd/m2, to prevent discomfort for patients and staff.

Lighting fixtures should be designed to minimize heat output to ensure patient comfort and safety.

Hospital lighting should be designed with patient comfort in mind, allowing for reading, working, resting, and safe movement.

Corridors should have 200-300 lux during the day. At night, this is reduced to 5-10 lux in corridors open to bed-bays and 10-50 lux in other corridors.

The placement of lights in corridors should be uneven to avoid discomfort for patients being transported on trolleys.

Lighting in corridors should help people adjust their vision when moving between lit and unlit areas.

Intensive care rooms require adaptable lighting for various tasks, including emergency situations. The illuminance level should be adjustable between 300 lux and near zero.

In intensive care, light sources with 'TL' color code 84 or 94 are recommended for their good color rendering.

Supplementary lighting fixtures are needed in intensive care to provide focused illumination for medical examinations and treatments.

Lighting in an X-ray room differs based on the type of examination. Some procedures require very dim lighting (10-30 lux), while others need brighter, general illumination (100 lux).

When directly observing the X-ray screen, low-level orientation lighting (less than 10 lux) should be provided to avoid glare.

Adding decorative lighting, such as a wall luminaire, can create a more pleasant and relaxing atmosphere in an X-ray room.

A hospital includes numerous spaces besides wards and intensive care, such as laboratories and kitchens, each requiring appropriate lighting for its specific purpose.

Lighting for many hospital rooms, including labs, offices, and lecture theatres, follows the same principles as similar spaces in other buildings.

Hospitals require specific lighting for service and communication areas, such as corridors and elevators.

Lighting design in hospitals should promote patient comfort and recovery by creating a similar, restful atmosphere in both wards and intensive care units.
