LED LAMP WITH VARIABLE INPUT POWER SUPPLY

摘要

There is provided a light emitting diode apparatus for operation with varying input electrical sources. The apparatus comprises an array of light emitting diodes to produce light, and a variable input power supply adapted to provide an electrical supply of predetermined value to the light emitting diodes from a varying electric signal provided by varying input electrical sources. In one embodiment, the light emitting diode apparatus is for use as a replacement of a fluorescent tube in an existing fluorescent fixture. In another embodiment, the light emitting diode apparatus is for use with connection to conventional AC voltage sources used throughout the world.
