2. Problem & Approach Problem: (1) Poor lighting in the emergency treatment room hinders healthcare staff from providing quality care. (2) Lighting system does not provide a healing environment for the patient. Solution: An integrated lighting system, the Balek System, that would provide clear and bright lights for working and provide ambient, diffuse lighting for patients while in waiting. Poor quality lighting for workingLack of healing environment for patients 8/19/20152To & Bessaad HS8803 ED Design

3. Design Considerations  Physician & nurses must be able to acquire working lights in an expedited manner  No complicated & complex lighting system.  Focal lighting must be clear, bright, white lights  No impurities in light properties. This prevents the light from obscuring any important facts during physical medical exams.  Patient must be provided with ambient lighting, and the patient must have control over the environment  Remote controlled lighting system.  There must also be general, diffuse lighting that allows for staff to provide room maintenance. Also, patients may not want the option of ambient lighting and prefer general white light instead.  The integrated lighting system should not be cost prohibitive  allow for economical and financially sound investment.

4. Balek Prototype Function & Design DESIGN: 1.Spot lights: The spot lights are located on three different panels: Panel A: provide lights for the patient’s head and neck region. Panel B: provide lights for the thorax and abdomen region. Panel C: provide lights for the legs. Note: Lights on each panel can be activated independently from other panels. 2. Full-spectrum lights: These lights are independently controlled from the spot lights and LED lights. 3. Multi-color LED lights: These lights cannot be turned on when the spot lights are in used and vice versa. This prevents distraction to the working staff, nurses, and doctors. The LED can change into seven different colors. They can be remotely controlled and have 3 modes: single color change, automatic discrete color change, and continuous color change. KEY Spot lights Full-spectrum lights Multi-color LED lights Blueprint of the Balek Lighting System FUNCTION: To provide lighting for: 1.Nurses & doctors: spot lights provide focal, clear, and intense lights for bedside procedures that require high visual acuity. 2.Staff: Full-spectrum lights provide general diffuse lights for various clinical procedures and room maintenance. 3.Patient: Multi-color LED lights create a more relaxing environment and provide positive distractions while in waiting. 2’9” 2’ 1’ 3’ Panel A Panel B Panel C LEDSpot light On/Off Spot light A On/Off Spot light B On/Off Spot light C On/Off LED On/Off Full-spec lights Light Controller Switch Box 8/19/20154To & Bessaad HS8803 ED Design
