Complete agreement:
•
LED will affect Incan, HID & CFL first
•
Impact of LED on LFL comes later:
– Shipments: ~2015
– Installed Base: 2020+
•
Significantly longer LED lifetime causes
lighting market to shrink $$$ by 2020

Advantages Of LED Arrays Over Discrete LEDs
LED Arrays
•
Discrete LEDs
Lower material cost
– Eliminates PCB cost and placement costs entirely
– Eliminates diffuser necessary to eliminate pixelation
•
Lower design cost
– One or two LED packages enable many different beam angles & lumens
– No PCB layout required
•
No reflow soldering
– Easier assembly limits the need for outsourcing
•
One light source instead of many
– Emulates the look of traditional lights
– Prevents multiple shadows in light beam
