In CASASOLO we believe that hospital lighting plays a fundamental role in the sense of wellbeing of all users, whether they are patients, staff or visitors.
Therefore, we propose every new project as an opportunity for R & D in which we apply the latest innovations and technology in lighting and maximize the amount of natural light in all hospital areas.
As we have seen in previous publications, the correct design of lighting in hospitals can very positively affect the recovery of patients.
Moreover, lighting can also improve staff efficiency. Nowadays, hospitals are genuine technological and medical research centers and the welfare of the researcher and scientific personnel is also a factor to consider for hospital managers.
For this reason, it is necessary to take into account the particularity and the demands of each of the spaces of a hospital because there are many different tasks that require a specific treatment depending on the level of perception that is required to perform them.
A specific lighting for every area of a hospital
Patient rooms lighting
Hospital rooms are where patients spend most of the time, for this reason, the main objective will be to design a nice lighting to help improve their well-being with the intention of creating a healthy environment and to foster a faster recovery.
Moreover, the rooms are also workspaces for staff and therefore require integrated facilities and adequate lighting levels in certain specific moments so they can carry out their work.
In the rooms, a bright and capacious space with 200 lux in most of its surfaces is recommended, avoiding excessive luminance (greater than 750 cd/m2), as these could increase the visual fatigue and stress of the patient.
Glare is another adverse effect in this case derived from a high contrast between two surfaces and to avoid it is advised to opt for indirect lighting.
It is important that the patient has control of the lighting from the bed, with an adjustable and accessible lighting in the headboard to allow a minimum of 300 lux for reading.
In turn, it is essential a good use of natural light and its possible regulation, and the use of luminaires with an attractive aesthetic and warm color temperatures that contribute to a feeling of domesticity.
In times when the hospital staff access to the room to examine the patient, an additional lighting of a minimum of 1000 lux for testing and treatment is required, either by headboard or movable luminaries.
During the night, it is recommended to guarantee a minimum of 5 lux in the room overall to ensure proper movement of nurses and safety, as they can access the room for routine checks.
This diversity of needs that occur in a hospital room during the day can be solved with a good design of the headboard of the bed, as this can integrate direct and indirect lighting, suitable for reading levels, recognition or general lighting and can also integrate other services with a higher technical complexity.
Lighting of recognition and treatment rooms
In the case of patient examination rooms, staff requirements are set in a first place to ensure their maximum performance and efficiency.
It is essential to achieve a high level of color rendering of the light sources so as to avoid creating shadows that could harm the personnel’s visibility.
The level of illuminance required may vary greatly depending on the type of treatment or task, from 5 to 1000 lux, since there are areas where the correct diagnosis requires a lack of lighting and for that a control system will be necessary to provide this versatility.
Lighting of operating rooms
In the operating room it becomes even more relevant the need for optimum lighting conditions which, in this case, can reach levels of up to 100,000 lux illuminance (achieved thanks to the specific lamps).
This is possible due to special lighting for the operating tables. It is also recommended to endow the space with a minimum of 2000 lux around the table and 1000 lux in the room.
Furthermore, the lighting of the adjacent rooms to operating rooms must have at least 500 lux to allow a gradual adaptation and avoid glare problems or disorientation.
Lighting intensive care units
Again, in the rooms of intensive care units the top priority it is to optimize the work of staff and for that different illuminance levels are set.
A minimum of 100 lux is stablished to ensure comfort throughout the room. Around the bed, it is recommended to increase the intensity up to 300 lux for the proper examination of the patient as well as the possibility of increasing this to 1,000 lux illuminance for more rigorous testing or even up to 2000 lux in emergencies.
Regarding the tone, it is a good option to opt for a neutral tone of the light source and to avoid the appearance of reflections in glass screens and monitors.
Lighting rehabilitation and therapy rooms
In this type of rooms in particular a good lighting can significantly contribute to the improvement of the patient’s psychological and greater motivation to perform rehabilitation exercises.
An average illuminance level of 300 lux with neutral tones might help to establish a friendly and convenient environment for such activities.
Lighting service areas
The illuminance level requirements in the areas of hospital services vary by type of activity.
While the laboratories and clinics require 500 lux, kitchens and laundries only need a minimum level of 200 lux.
The office, however, also requires a level of illuminance of 500 lux with neutral tones and low luminance lighting to prevent reflections on computer screens.
