Summer Research Internship Final Project Presentation July 30, 2015 Exploring Innovative OLED Luminaire i Design Kasia Kozak Rochester Institute of Technology Mentor: Yiting Zhu.
Project Goal 5 The goal of this project was to explore the unique characteristics of OLEDs through luminaire design.
Method 6 I. Identify the distinguishing characteristics of OLEDs that make them desirable in developing lighting markets II. Identify the best areas for lighting applications for current OLED technology III. Develop and test concepts for an OLED luminaire IV. Create a working gprototype of luminaire using OLED panels V. Install luminaire in the LRC s modular DC-grid concept room
Claimed Features of OLEDs 7 Physical Qualities Thin Flexible Variety of shapes Transparent Minimal thermal management Light Qualities Low glare Diffusive light Large area light source General LED Qualities Dimmable Color tunable Energy saving 100% recyclable Photo: http://www.oldhouseweb.com/blog/aerelight the trendiest desk lamp on earth/
Lighting Background 8 Goals of lighting: Functional Decorative Emotional How are these goals achieved? Layering light Ambient Accent Task http://wholehomefurniture.com/wp content/uploads/2014/03/interior design lighting 238.jpg
Design Opportunities for OLEDs 9 The designed luminaire will be integrated into the LRC's modular DC-grid concept room; therefore, the focus will be on ceilingand wall-mounted fixtures. OLED Light Output Diffuse Low glare Low luminance Opp portunit ty Design Conditions Wall or ceiling mounted Ambient or task
Design Intent 10 Design a decorative wall or ceiling-mounted fixture that t showcases the unique features of OLEDs. http://www.acuitybrands.com/oled/ /media/images/acuity/oled/why%20oled/curved%20oled%20panel%20in%20hand.jpg
Initial Concept Sketches 11
Digital Modeling 12 Digital rendering allows for visualization of material a and color options.
Prototyping 13 Prototypes allow exploration of the physical form in full scale and help to evolve the design. Requirement: Americans with Disabilities Act requires outward extension of no more than 4" if luminaire is mounted below 6' 8" above floor. All of the designs have an arc of 4" or less from the wall.
Design Details 14 F. A. B. C. D. E. A. Sconce with rotating OLED panels B. OLED panels embedded in solid material C. OLED panels on track D. Square OLED panels E. Crossover task light/sconce F. Ceiling-mounted wave form with circular panels
Survey 15 A small-group survey: To understand user preference (Vote for favorite fixture) Queried specific features movability, modularity, shape
Survey Results 16 Majority winner Ceiling-mounted wave When polled, subjects responded nearly equally to circles and squares in this design. Squares were chosen based on timely availability of OLEDs. The survey also revealed that modularity is a desirable feature in a light fixture. How can modularity be incorporated into the design?
Modular Design 17 Modular system of concave and convex fixtures used to create a light and fluid waveform.
Final Design 18
Luminaire in Context 19
Modularity 20 Can be combined in different ways Concave only Convex only Waveform can be elongated indefinitely
Materials & Construction 21 Aluminum Tubing Driver Electronics 3D Printed ABS Plastic Magnetic connector 100mm x 100mm LG Chem OLED Panels
Luminaire Performance 22 Performance: Total input power*: 10 W Total light output: 507 lm Efficacy: 49 lm/w Luminance: 2928 cd/m 2 CCT: 3572 K CRI= 89 and GAI = 67 Avg. illuminance = 71 lx Max. illuminance = 93 lx Min. illuminance = 38 lx 54 *Input power to panels
Demonstration 23 The product is demonstrated at the LRC s modular DC grid concept room. A survey was conducted to evaluate project success.
Post Evaluation 24 Were the Project Goals Achieved? Strongly Disagree Disagree Neutral Agree Strongly Agree Exhibits thin qualities. Exhibits diffuse light qualities. Successful use of modularity. Overall impression of design. Fixture is functional. Fixture is decorative.
Customizing the Luminaire 25 Adding personality to the fixture: Customizable / swappable cover and frame Cutting edge manufacturing: 3D Printing Add patterns Change colors Made possible due to easy thermal management requirements
Summary 26 Survey results: - Luminaire demonstrates thin, low glare, and diffuse light qualities - Decorative goal can be achieved by OLEDs - Functionality can be improved by: - Increasing the OLED s light output - Installing the fixture closer to the task area
