This document proposes a design for an OLED light therapy system that provides full spectrum light in a non-invasive way to help slow cognitive decline. The system would use flexible, transparent OLED panels installed like vinyl stickers. It would have adjustable brightness settings, a timer, and sensors to automatically turn on based on light levels or detect motion. The design aims to make light therapy easier to use while improving mood, wellbeing and independence for those with cognitive impairments like Alzheimer's disease.

1. „UNIVERSAL DESIGN‟
DESIGNING FOR THE REST OF US
Design a product to help those with physical or
cognitive impairments that is also appealing to
the mass market.

2. Named after
Personality/Behavioural changes
German physician
Alois Alzheimer

3. Normal Alzheimer‟s

4. HOW DOES IT START? THERE IS NO CURE
Unknown, but factors include: Make life easier
Hereditary Factors Prolong Independence
Environmental Factors Full Spectrum Light Therapy
(head trauma/educational
level/early life experiences)

5. FULL SPECTRUM
LIGHT THERAPY
Sit/stand stationary
2-3 feet away
1-4 hours a day
In winter and dull periods of summer

6. BRIGHT SUNNY DAY
= 100,000 lux
AVERAGE LIGHTBULB
= 250 – 500 lux
FULL SPECTRUM LIGHT
= 5,000 – 10,000 lux

7. RESETS CIRCADIAN RHYTHM
(light and dark cycle)
• Prevents „Sundown Syndrome‟
• Maintains 24 hour sleeping pattern
• Slows cognitive deterioration
• Decreases symptoms of depression

8. “clunky”
“small buttons”
“unintuitive”

9. DESIGN A NEW WAY OF BRINGING FULL SPECTRUM LIGHT THERAPY INTO THE HOME
AIMS FOR THE DESIGN: HEALTHWISE
• Be Harmonious/Non-invasive • Prolong Independence
• Not be obviously medical • Improve mood and general
• Does not require manual interaction wellbeing
• Easy to use • Take the strain off the NHS and
care homes
35 million people worldwide
5th leading cause of death in people aged 65 or over

10. FULL SPECTRUM OLED PANELS ON FLEXIBLE,
TRANSPARENT PLASTIC SUBSTRATE
INSTALLATION SIMILAR TO VINYL
STICKERS
WATERPROOF PROTECTIVE LAYER
FOR EASY CLEANING
2 LIGHT MATRIXES:
1. FULL SPECTRUM MINUS BLUE
Adjustable brightness
2. BLUE LIGHT – ACTIVATED ON FULL
POWER
The beneficial wavelength
Completes the spectrum

11. Easy to produce (inkjet printers)
Thinner, more flexible, lighter
Can be plastic (LEDs/LCDs have to be glass)
Softer, more diffused light
Brighter – can be multi-layered, glass absorbs light
Brightness controlled by current
Lower power consumption (no backlighting)
Generate own light
Larger field of view (170º)
Can be made in large sheets
Can be transparent and/or flexible

12. How do OLEDS work?
Electrophosphorescence
ELECTRONS
(electrical current)
LIGHT

14. Induction charged
Wireless control unit
Base unit connected to mains
power and OLED window system

15. ON/OFF BUTTON FOR WHOLE LIGHT SYSTEM
TOUCH SENSITIVE DIMMER DIAL
FULL POWER = FULL SPECTRUM
ON/OFF BUTTON FOR FULL SPECTRUM
TIMER SYSTEM
OVERRIDES DIMMER DIAL
CANNOT EXCEED 4 HOURS A DAY
ON/OFF BUTTON FOR AUTOMATED ONE
HOUR ROTATION (10 MINS FULL SPECTRUM)
OVERRIDES MANUAL SETTINGS
FADES IN AND OUT GRADUALLY

16. PHOTOVOLTAIC SENSOR
CAMERA SENSOR
Light automatically turns on
when light levels outside go Lights only stay on when
below a certain level there is a person in the room,
to save energy
If product used as a system in
all rooms of the house, only the
MOTION SENSOR
lights within rooms in use will be on
OLED display on control unit
only glows when a person is
within 1.5m of it

17. UP TO 85% TRANSPARENCY
When light is off
LIGHT TRAVELS IN BOTH DIRECTIONS
Light visible from outside
EXTRA PRIVACY
Inside area not visible from outside
BLOCKS SHADOWS
Another catalyst for „Sundown
Syndrome‟
ECO-FRIENDLY
More energy-efficient than LEDs or
lightbulbs

18. SCIENTIFIC CLAIMS THAT BLUE LIGHT CAN CAUSE RETINAL DAMAGE
Especially in people who already have glaucoma
or other macular degeneration
LIFE SPAN OF BLUE OLEDS
Blue OLEDs = 14,000 hours
(4 hours a day = nearly 10 years)
Green and red OLEDs = 46,000 - 230,000 hours
WATER DAMAGE TO OLEDS

19. DIY KITS FOR SELF-INSTALL
COMMERCIAL APPLICATION
SYSTEM SOLD AS A SERVICE Could be used in carehomes
and hospitals
FULL WINDOW REPLACEMENT
3 TIERS OF EXPENSE
