What is LEDWhat is LED
Light Emitting DiodeProviding current to LEDs – constant current drivingHigher driving current, higher brightness – but should smaller than its upper boundIF: forward current
[Typ: 1W(350mA), 3W(700mA), 5W(1A)]VF: forward voltage
[Typ: white 3.5V (2.8~4V)]Life > 100,000 hours (degenerate to 50% of initial brightness)Need sufficient heat-sinking, temp.↑, brightness ↓, life ↓

Constant Voltage VS. Constant CurrentConstant Voltage VS. Constant Current
Constant Voltage (C.V.) PSUOutput voltage is a constant value General MW AC/DC PSU (ex. S-100, S-60, RS-25….) Can’t connect to LEDs directly, need the LED driving IC(constant current IC)Suitable for higher wattage LED applications (ex. SP-320, RSP-1500)
Constant Current (C.C.) PSU Output current is a constant valueCLG / PLN / ELN / LPC seriesSuitable for direct connection to LEDsSemi-constant current (50% or 70%): have constraint on series connection number of LEDs (ex. CLG, PLN)

Overview of LED DevelopmentOverview of LED Development
Using LED to replace light-bulb traffic sign can save 80% of energyASP of high-brightness white LED -70% in 5 years (02~07) (now: 1W=1USD)High- brightness white LED represent 66% of total LED market in 2006 Efficiency of high- brightness white LED increase from 35lm/W to around 80lm/WEfficiency of traditional lighting: around 100lm/WLeader in the market: 150lm/W (Japan)Using 100W LED streetlamp to substitute 400Wtraditional mercury streetlamp (Taiwan) – still 3~4 times more expensive, but will get closer soon!
MotivationMotivation
LED moving sign is one of the main application field for MW PSUHigh dust / moisture application Previously: no IP + protection structureUL1310 Class 2 requirementBooming of LED related usage lighting
First product in 2006: CLG/PLN-100, over 20K been soldPrompt expansion: 4 families / 13 seriesMost frequent asked products in Taitronic and electronica Asia in 2007
