Healthy Lighting: Spotlight on Patient Rooms

  1. Lighting Design Approach
    • The lighting must be developed as part of a holistic approach to the design of the patient’s room. The lighting design strategy, hardware, and controls must work with all of the other systems to optimize the level of care and the comfort of the patient.
    • Developing this lighting design approach becomes akin to building a kit of parts which can be developed across a hospital or healthcare facility as a whole, thereby reducing maintenance needs and providing a consistent light quality.
  1. Lighting Response to Specific Types of Patient Rooms
    • Typical Patient Room
      • Indirect ambient lighting with low glare light fixtures.
      • Focused reading lights located behind the patient’s head.
      • Low illuminance nightlight to illuminate path to bathroom.
      • Low illumination observation lighting to be provided on either side of the patient bed where electronic recorded keeping takes place.
      • Wet rated, non-conductive, vandal resistant shower lighting to be provided.
    • Examination Rooms
      • Fully adjustable recessed lighting should be provided to be able to examine a full range of patient needs. Fully recessed wipe-down lights are recommended for reducing the spread of bacteria and germs.
      • Provide recessed downlighting:
        • Prevents the light source being seen from normal lines of sight (cutoff angle between 40° and 50° from horizontal).
        • Greatly reduces the possibility of hazards.
        • Makes maintenance and cleaning of fixture easier.
        • Has a high value because it provides high efficiency at a lower cost.
      • Lighting must be provided with a level of redundancy in case of problems or emergency.
    • Clean Rooms
      • Surfaces of light fixtures should be fully recessed with minimal protrusion into room.
      • Light fixtures must be provided with anti microbial finishes.
      • Lighting fixtures must be rated for a clean room environment.
  1. Lighting Technology Needs
    • Provide a fully resilient design that it prepared for extreme events.
    • Lighting to be provided with sustainable light sources such as LED and CFL to maximize energy efficiency and provide cost savings.
    • Provide lighting solutions that increase the user’s connection with nature. Therefore improving the end users mental health; reduce stress and overall improvement of their well-being.
    • High Color Rendering Index (CRI) to be provided to ensure the healthcare physician can accurately evaluate the patient.
    • All lighting to be provided with minimal source brightness. Glare control accessories to be provided where required.
  1. Lighting Control Needs
    • All Lighting to be provided with dimming control that can smoothly dim the lighting to permit low light levels at night to minimize eye adaptation.
    • Patient to be provided with illuminated switches to control certain lighting:
      • Ambient lighting with a recommended lighting level of 10 footcandles (fc)
      • Reading lights with a recommended lighting level of 50 fc
      • Shower lighting with a recommended lighting level of 30-50 fc
    • Doctors/Nurses to control certain lighting
      • Examination lighting with a recommended lighting level of 100-300 fc
      • Nightlight to be on switch or photocell with a recommended lighting level of 3 fc
      • Observation lighting to be provided with dim red amber light switched at the door.
