Leading LED manufacturers have recently introduced HBLEDs with over 80 lumens/W, making it possible to replace halogen lamps in light fixtures such as the MR16 spotlights. The migration from conventional halogen light sources to HBLEDs carries the promise of significant A power savings and extended product life. According to the market research firm Strategies Unlimited, growth in the highbrightness LED market in the next 3 to 5 years will be driven by lighting, display backlighting, and automotive applications, and the overall market will reach $9 billion by 2011. LED rEquirEs constant currEnt Home Page Product Training Module Online Ordering Suppliers Catalog The higher lumens needed for lighting applications require the use of high-power HBLEDs. The forward current for these LEDs are in the range of 350 mA to over 1 A. The forward-voltage drop varies from 2.8 to 4.5 V for the white, blue, and green 5 | Project lighting | aPr 08 http://maxim-ic.com/led http://digikey.com/ http://ad.doubleclick.net/clk;198717884;26055153;t http://ad.doubleclick.net/clk;198717989;26055167;e http://ad.doubleclick.net/clk;198717988;26055168;e http://ad.doubleclick.net/clk;198717986;26055170;v http://ad.doubleclick.net/clk;198717985;26055171;v
