4. History of LED

5. Mistake #1 – Not evaluating LED
By the end of this presentation, I hope you’ll all be convinced you are a candidate for LED and ready to get an assessment.
It’s too expensive
We can’t afford it
It wouldn’t be worth it
Special applications

6. History of LED Luminescence of carborundum crystal discovered in 1907
Scientist at General Electric made the first useable LED in the visible spectrum in 1962
Prices of LEDs came down in the 1970s - Early uses were in Screen displays, TV remotes, calculators and watches
Early 2010’s – LED starts to gain commercial / residential viability as an expensive but efficient competitor to fluorescent

7. How it Works
Direct current
Luminescence

8. How it works Like a solar panel in reverse.
A P-N junction can convert absorbed light energy into a proportional electric current. The same process is reversed here (i.e. the P-N junction emits light when electrical energy is applied to it).

9. How it Works - Drivers
LEDs are designed to run on low voltage (12-24V), direct current electricity. However, most places supply higher voltage ( V), alternating current electricity. An LED driver’s main purpose is to rectify higher voltage, alternating current to low voltage, direct current.

10. Advantages of LED Lower energy consumption Longer lifetime
Improved physical robustness
Smaller size
Faster switching

11. Disadvantages of LED Sensitivity to heat Maintenance factors
Fit into existing fixtures / applications
Easy to overlight

12. Mistake #2 – Over- & Under-Lighting
By the end of this presentation, I hope you’ll all be convinced you are a candidate for LED and ready to get an assessment.
The more light the better
Same fixture throughout the building
Glare and Shielding

13. Light Pollution
Light of the Living Dead

14. Lighting Projects
Visibility, color rendering and safety

15. Safety

16. Focus

17. Color Rendering Index

18. Energy Projects

19. Mistake #3 – Not considering other savings or value from LED
Cows produce more milk,
Increased productivity
Safety
Maintenance
Industry Specific

20. Rebates

21. Bureaucracy in Lighting Fraud, watered down standards, knock-offs

22. Mistake #4 – Not evaluating controls
Cows produce more milk,
Conservation vs Efficiency
Maximize rebates
Maximize savings

23. The Price is Light

24. Energy Savings Examples
