ABSTRACT:
LED-based light bulbs having one or more white LEDs, for replacing/retrofitting conventional light bulbs. An exemplary bulb includes at least one first white LED and at least one power connection having a form configured to engage mechanically and electrically with one of a conventional Edison-mount (screw-type) light bulb socket, a conventional fluorescent tube coupler arrangement, and a conventional halogen MR-16 socket arrangement. The bulb further includes at least one voltage transformation device configured to electrically transform a first voltage applied to the at least one power connection (via the corresponding conventional socket/coupler) to a second voltage that provides operating power to at least the white LED(s). The LED-based light bulb substantially corresponds in shape to a corresponding one of a conventional Edison-mount screw-type light bulb, a conventional fluorescent tube, and a conventional halogen MR-16 light bulb, based on the form of the at least one power connection.
