Intensive care lighting

People who are seriously ill need rest and subdued lighting; constant monitoring and emergency treatment require a higher lighting level. So recovery rooms, intensive care units and intermediate wards need a flexible lighting system permitting different levels of brightness:

predominantly indirect lighting providing 100 lux illuminance for the lighting comfort needed to promote convalescence;

supplementary direct lighting producing 300 lux illuminance for simple bedside examinations and treatment. This can also be used by the patient for reading. To avoid disturbing others in the room, the use of a portable reading luminaire is recommended.

1,000 lux illuminance for emergencies. This ensures that every detail can be clearly and reliably made out by doctors and nursing staff.

Emergency lighting is realised either by activating more luminaires or by switching on all the lamps in three-lamp luminaires instead of just one lamp for 300 lux.

The most suitable light colour is neutral white, with a colour temperature between 3,800 and 5,300 degrees Kelvin. Lamps need to have a colour rendering index of Ra ≥ 90.( from www.greendyled.com)
