October 1, 2009[Ideas For Design] High Power-Factor LED Driver Converts AC Input To Power Halogen Replacement
HIGH-BRIGHTNESS LEDS ARE AN inexpensive, robust, and green replacement for halogen light bulbs. LEDs offer a much longer lifetime and eliminate the safety hazards of the inert gas, the expense of the UV filter encasement, and the handling sensitivity of halogens. Since halogen bulbs typically are driven with 12 or 24 V due to their excellent efficacy at those voltages, buildings have been wired with 12- and 24-V ac transformers for halogen...
June 23, 2005[Ideas For Design] Wide Input-Voltage SEPIC Drives High-Power White LEDs
Recently, white LEDs have made sizable performance gains by squeezing extreme luminous density into ultra-compact packages. The latest white LEDs hold numerous advantages over more conventional lighting, including improved spectral characteristics, shorter response time, greater luminescence, greater durability, longer life, and decreased size. The Lumileds Luxeon V, for instance, boasts up to 50 times the flux, and at least 20 times the luminous density, of a standard...
