Household LED lamps
Household LED lamps Replacement for existing lighting LED lamps are made of arrays of SMD modules that replace incandescent or compact fluorescent lamps, mostly replacing incandescent lamps rated from 5 to 60 watts. Such lamps are made with standard lamp connections and shapes, such as an Edison screw base, an MR16 shape with a bi-pin base, or a GU5.3 (bi-pin cap) or GU10 (bayonet fitting) and are made compatible with the voltage supplied to the sockets. They include driver circuitry to rectify the AC power and convert the voltage to an appropriate value, usually a switched-mode power supply.Lamp sizes and bases As of 2010 some LED lamps replaced higher wattage bulbs; for example, one manufacturer claimed a 16-watt LED lamp was as bright as a 150 W halogen lamp A standard general-purpose incandescent bulb emits light at an efficiency of about 14 to 17 lumens/W depending on its size an...
