<p>An electromagnetic radiation emitting bulb (120), comprising a housing (190); one or more power input terminals (130.140) disposed on the housing (190); a voltage converter (110) disposed within the housing (190) where the voltage converter (110) is electrically connected to the one or more power input terminals (130,140); and one or more electromagnetic radiation emitting devices (120) disposed within the housing (190) where those one or more electromagnetic radiation emitting devices (120) are electrically connected to the voltage converter (110). A method to emit electromagnetic radiation from a hand-carried device (100) comprising an electromagnetic radiation emitting bulb (120) and one or more battery cells. The method supplies first DC power having a first voltage from the one or more battery cells to the bulb (120), converts within the bulb the first DC power to second DC power having a second voltage, supplies within the bulb the second DC power to one or more electromagnetic radiation emitting devices (120), and emits electromagnetic radiation.</p> |
