| Title: |
Conventionally-Shaped Light Bulbs Employing White LEDs |
| 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.
