| PHONE: The Power Of Light Lighting the way Forward Old Technology Next Generation Technology Current Technology

| PHONE:  Architectural lighting  Discrete LED lighting  Display case lighting  Electronic signs  Mass transit lighting and signaling  Theatrical lighting  Traffic signals  Under cabinet lighting  Automotive lighting  Indoor/Outdoor lighting  Laptops/portable displays LED Applications

| PHONE: What is Driving the Lighting Market to LED and SSL? Why are LED’s being used in new lighting applications? Rising cost of energy Falling cost of technology LED cost per lumen decreased by 30% over the past year Government regulations RoHs (reduction in mercury content impact CFL devices) Emissions reduction targets Building performance requirements Increase in use of lighting controls Energy efficiency requirements

| PHONE:  LED light output is directly proportional to the forward current  More Power = brighter lights  More Power = more need for capacitors and LOW LEAKAGE circuit protection equipment  A drive/control circuit must be used to control the LED’s current  More ICs = increased component count  LED’s reverse breakdown voltage usually low (5V to 10V)  The designer must be careful to insure protection of the device  LED’s are ESD sensitive  More opportunities for varistor based product LED & Circuit Protection
