According to Reuters in a hospital ward lighting can help doctors and nurses to medical patients, but too bright lights would not only cause damage to the retina, will also affect the circadian cycle of the patient. The study found that if traditional hospital lighting is replaced with adjustable LED lighting, it will be able to adjust the brightness and darkness to meet the needs of patients, and help to restore.
The Rensselaer Polytechnic Institute has done a series of studies on the impact of lighting on humans. Different types of hospitals and different patient levels in hospital lighting require different lighting solutions. Adjustable LED lighting mimics natural light for a comfortable resting environment.
In 2016, Philip Lighting teamed up with the University of Minnesota Masonic Children's Hospital to install an adjustable LED lighting system in several Intensive Cure Units (ICUs) in the hospital. About 10 LEDs are placed in different positions on the ceiling and walls. The system automatically adjusts the brightness according to the time and the number of people in the room. The patient and the caregiver can manually adjust the lighting of the room through the flat interface.
Patricia Rizzo, senior lighting application designer at Philips Lighting, said: "This adjustable LED lighting system is beneficial to ICU patients who have been hospitalized for a long time, and 80% of patients have acute mental status (delirium), which makes them unconscious. There may also be hallucinations, and the illumination system that mimics natural light makes the patient more conscious of time."
Rizzo also mentioned that the LED lights on the wall can also be transformed into different colors like pink, green and blue. The sick child can change the color by manipulating the tablet while distracting their attention to relieve the pain.
In addition to helping the patient to recover, the device's adjustable LED lighting system allows LEDs to save about 80% of the electricity in each ward, and the hospital can invest the savings in other areas.
