The lighting in a hospital ward can help doctors and nurses treat patients, but too bright lights can not only damage the retina but also affect the patient's circadian cycle. The study found that if the traditional hospital lighting is replaced by adjustable LED lighting, it will be able to adjust the light and dark for the patient's needs to help restore.
The Rensselaer Polytechnic Institute has done a series of studies on the effects of lighting on humans. Different types of rooms and different patient levels in hospital lighting will require different lighting solutions. Adjustable LED lighting can imitate natural light and provide a comfortable rest environment for the patient.
In 2016, Philip Lighting worked with the University of Minnesota’s Masonic Children’s Hospital to install adjustable LED lighting systems in several of the hospital’s Intensive Cure Units (ICUs). There are about 10 LED lights in different positions on the ceiling and wall. The system automatically adjusts the light and shade according to the time and the number of people in the room. The patient and nursing staff can manually adjust the lighting of the room through the flat panel interface.
Patricia Rizzo, senior lighting application designer at Philips Lighting, said: “This adjustable LED lighting system has helped many ICU patients who have been hospitalized for long periods of time. 80% of patients have an acute mental status (delirium), causing them to be insane There may also be hallucinations, and the lighting system that mimics natural light makes patients more aware 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 children can change the color by manipulating the tablet while distracting their attention to relieve pain.
In addition to the device-adjustable LED lighting system that can help patients recover, the use of LED lights can save about 80% of the electricity in each ward, and the hospital can also invest the savings in other areas.
