LED Lights: The Future of Lighting. Lowen Okamoto Mentor: Dan O’Connell. Reasons of Interest. Cost of energy is quickly increasing Cut costs on electricity bill Maintain green & sustainable environment. Overview. What is an LED? How do they work? My Project on LED lights
Mentor: Dan O’Connell
Glows when red hot
Much energy is wasted
Light Emitting Diode
Small silicon crystals “doped” with phosphor atoms
Free electrons become excited producing photons
No heat outputHow do they work?
Visible spectrum 400-780 nm
