1 LED Lighting / Class 2 / Waterproof Series What is LED Light Emitting Diode Providing current to LEDs constant current driving Higher driving current, higher brightness but should smaller than its upper bound I F : forward current [Typ: 1W(350mA), 3W(700mA), 5W(1A)] F : forward voltage [Typ: white 3.5 (2.8~4)] Life > 100,000 hours (degenerate to 50% of initial brightness) Need sufficient heat-sinking, temp., brightness, life 1.5 f = 3.5 C-1

2 Constant oltage S. Constant Current Constant oltage (C..) PSU Output 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 value CLG / PLN / ELN / LPC series Suitable for direct connection to LEDs Semi-constant current (50% or 70%): have constraint on series connection number of LEDs (ex. CLG, PLN) Typical LED Driving by CC Mode PSU 1.25A 1.25A 0.3A A 0.31A A 0.315A A 0.325A A 1.25A / 4 = A Suggested parallel LED rows: 4 (Mainly for better balance of current sharing) C-2

3 Overview of LED Development Using LED to replace light-bulb traffic sign can save 80% of energy ASP 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/W Efficiency of traditional lighting: around 100lm/W Leader in the market: 150lm/W (Japan) Using 100W LED streetlamp to substitute 400W traditional mercury streetlamp (Taiwan) still 3~4 times more expensive, but will get closer soon!
