Intensive care and examination rooms

Intensive care is normally the entry point for a critically ill or injured patient into the hospital. Visual examination plays a major role in deciding the right treatment. This demands a high level of general illumination as well as good colour rendering.

Arm mounted examination lights fitted into wall or ceiling brackets, along with strong general lighting and high colour rendering provide the perfect light sources. Ceiling mounted luminaires are the best option in these areas in order to achieve an adequate general lighting level of minimum 500 lux.

Medically certified examination luminaires can be mounted on to the wall, ceiling, table or trolley stand and used as for general examination lighting or for smaller interventions/procedures. Armbased examination lights give light exactly where needed and comes with narrow and wide light distributions.

Lighting requirements in EN 12464-1

*CCT = Colour temperature

In some enclosed places such as offices, education, health care and general areas of entrance, corridors, stairs, etc., the walls and ceiling need to be brighter. In these places it is recommended that the maintained illuminances on the major surfaces should have the following values: Ēm > 75 lx with Uo ≥ 0,10 on the walls and Ēm > 50 lx with Uo ≥ 0,10 on the ceiling. The maintained mean cylindrical illuminance (average vertical plane illuminance) in the activity and interior areas shall be not less than 50 lx with Uo ≥ 0,10, on a horizontal plane at a specified height, for example 1,2 m for sitting people and 1,6 m for standing people above the floor.
In areas, where good visual communication is important, especially in offices, meeting and teaching areas, Ēz should not be less than 150 lx with Uo ≥ 0,10.
For uniform arrangement of luminaires or roof lights a value between 0,30 and 0,60 is an indicator of good modelling.
