The lights are controlled by a mobile application. Physicians can control and fine tune all the lighting systems, modifying them based on patient needs by using the application from anywhere in the hospital. Patients can control the ambiance lighting and reading lights through the application.This application will come preset with default settings for circadian lighting, but will be customizable to best fit the patient’s needs if necessary.Intense, sudden light is not comfortable for a patient residing in a dim room. To avoid the lights suddenly being turned on, the app will have a button for staff to press a little bit before entering the room. This will make the lights gradually become brighter, making for a more comfortable patient experience. Importance was given to ease of use by patients. The overall system consists of four components along with the application:
The Day/Night Simulator will mimic the natural day and night cycle. These tunable lights will produce a wide range of white light, and can be adjusted to a wake time and sleep time by the physician as per patient needs. Wake time and Sleep time settings will alter the amount of blue light emitted, in order to promote sleep.
The Ambiance LED lights around the edges of the room will help enhance the mood and visual experience, improving the patient’s sense of wellbeing by providing a wide range of colored light. Patients will be given a wide range of ambience presets (Eg: Afternoon, Mountain, Rainy Day, Summer Beach) to choose from.
Controllable reading lights with low blue light emissions allow for reading without impacting the patient’s sleep cycle. These lights can be adjusted with different brightness setups as well as at different angles in which light falls. This light is placed close to the patient bed.
Examination lights, which can be remotely activated, will assist in caregiving. Staff can notify these lights in advance during routine checkups. Once notified, the light will gradually increase its brightness within 5 minutes. This avoids sudden bursts of light that cause sleep interruptions during patient checkups.
