Lighting in hospital wards can help doctors and nurses diagnose and treat patients, but overlighting can damage not only the retina, but also the circadian rhythm of patients. The study found that if the traditional hospital lighting is replaced by adjustable LED lighting, it will be able to adjust the brightness and darkness according to the needs of patients, which will help to restore.
Rensselaer Polytechnic Institute has done a series of studies on the impact of lighting on human beings. In hospital lighting, different types of rooms, different levels of patients will require different lighting schemes. Adjustable LED lighting can imitate natural light, so that patients can have a comfortable rest environment.
In 2016, Philip Lighting and the University of Minnesota Masonic Children's Hospital collaborated to install adjustable LED lighting systems in several of the hospital's pediatric intensive care units (ICUs). About 10 LED lights are set at different locations on the ceiling and walls. The system automatically adjusts the light and shade according to the time and number of people in the room. Patients and nurses can manually adjust the light in the room through the flat panel interface.
Patricia Rizzo, senior lighting application designer at Philips Lighting, said: "This adjustable LED lighting system is good for long-term hospitalization in ICU patients, 80% of patients have acute mental illness (delirium), leading them to confusion and may also produce hallucinations, mimicking natural light systems so that patients on time More conscious. "
Rizzo also notes that LED lights on the walls can also change colors like pink, green and blue, and that sick children can change colors by manipulating the panel, while distracting them from pain.
Apart from helping patients recover, the use of LED lights can save about 80% of the electricity in each ward, and hospitals can invest the savings in other areas.
