Driving a High Lumen LED cost effectively

desai_amogh

Hi, Can we drive this kind of High Lumen LEDs without a Voltage Booster IC?? http://in.rsdelivers.com/product/osram-opto-semiconductors/gw-p9lrs1em-pqps-40s7/duris-s8-led-white-4000k-7-step/7916924.aspx For example directly through mains (230v) using a DC regulated power supply ?? Its Forward Voltage is 26.6  and Forward current  10mA to 240mA I am actually trying to find a cheaper way to drive High lumen LEDs. I'd welcome other ideas or circuit diagram for this ! Thanks -Amogh

most people , Amogh jee, <br /> are using this schematic.<br /> i had bought few bulbs and saw internal sch .<br /> http://www.circuitstoday.com/wp-content/uploads/2010/06/mains-optd-led.jpg

Higher lumen means more bright lights

LED bulbs are the in light for most of the cars. But for road safety rules are that one would use the halogen lights. Many LED lights are banned. However, the big and huge SUV cars can have them.

What you are referning to are called HID projector lights.
