Advanced LED Applications Including Lighting By: Austin Walz Abstract: LED or light emitting diodes have been a huge advancement of the 21 st century. They have many benefits and a promising future.
2
Outline Benefits of LED lighting Drawbacks Specs Directional Lighting Examples AC LEDs
3
Benefits of using LED lights Efficiency Lifetime Low Power Consumption Directional Lighting Brightness Don’t create heat Color Fast Start Up
4
Drawbacks of LEDS Heat Cost Change Color with Age
5
Color Rendering Index (CRI) Lights ability to show true color On scale from 0-100 Most LEDs 90+
6
Color Temperature Over 5000K considered “cool” 2700-3000k considered “warm”
7
Lumens Measure of the total quantity of visible light emitted by a source.
8
Directional Lighting
