1. The Future of Light
Since the dawn of time, mankind has wanted Artificial Light
Today, we live, work and play under electric light – mostly bulbs and tubes
But the LED Lights are coming

2. The Earth at Night
In a typical home, 1/5th of electricity is used for light
Lighting uses lots of electricity
We waste a lot of light

3. LED Light bulbs – efficient but…
One of the better LED bulbs today
Equivalent to 60W incandescent bulb, but uses only 12 W
Cost is about $40
Philips
L-Prize
Submission
Why does it look so unusual???

4. How do you make a White LED?
Blue LED +
Yellowish Phosphor
Note – we have lots of white LEDs. Each student should have one and they should be able to see the yellow phosphor in the cup.

5. Can we do more with Lighting?

6. Smart Lighting Vision Synthesizing Light for the Benefit of Humanity
Lighting Beyond the Bulb
Better Health
Huge Energy Savings
Data from Light (no RF)

7. New Materials and Methods
Smart Lighting
New Semiconductors
New Materials and Methods
Systems Level Thinking
Creative Problem Solving
Needs wide variety of skills
Growth area – ties to Energy and Sustainability
Flexibility for Artistic Expression
Ties to Health, Architecture, Art, and Healthy Living
Disruptive Technology – New Markets and Opportunities
Global Interest, Global Investment, Huge Opportunities
Chemistry and Physics you can SEE
Lighting and Design with ties to Art, Physiology, Agriculture and Entertainment

8. Engineering Design Process
Collect relevant basic knowledge from math, physics, chemistry, etc.
Develop an ideal model and use the model to predict system behavior (paper and pencil analysis)
Apply simulation tools to predict system behavior based on the ideal model incorporating the characteristics of real components.
Build and test a prototype system (e.g. experiment with an actual circuit)
Develop a practical model and establish its limits of applicability

9. Many Ways to Show This Process
From Mechatronics
Probably too Complex
Other Ideas: Check out the video From Oklahoma State (very good)

10. Simplified Cycle Diagram
Math & Science Info
Ideal Model
Simulation
Experiment
Practical Model

11. Apply to Science Fair Projects?
Hydropower versus wind power
Soil fertility and conductivity

12. The Method is Not so Simple
The process does not follow the simple cycle
There is info shared with every step
There also has to be an output
Math & Science Info
System Model
Simulation
Experiment
