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
