Light tube and power supply circuit
First Claim
1. A method for providing a light tube for mounting within a conventional fluorescent light tube socket, the method comprising:
- disposing the plurality of light emitting diodes on a rigid support structure, the rigid support structure comprising spaced-apart sidewalls forming a channel and a planar portion having a first surface extending in the channel formed by the sidewalls, the light emitting diodes being disposed on the first surface;
disposing the support structure and plurality of light emitting diodes within a tubular housing comprising a transmissive cover for the light emitting diodes, wherein at least a portion of the sidewalls contact an interior surface of the tubular housing; and
disposing a pair of end caps at opposite ends of the tubular housing, each end cap configured to fit with the conventional fluorescent light tube socket.

Abstract
A replacement light tube for replacing a fluorescent light tube includes a bulb portion extending between a first end and a second end, the bulb portion comprising a support structure, a plurality of white light emitting diodes (LEDs) and an elongate light-transmissive cover. The support structure has a first surface extending between the first end and the second end. The plurality of LEDs are supported by the first surface and arranged between the first end and the second end. The elongate light-transmissive cover extends between the first end and the second end and over the first surface of the support structure. A first end cap and a second end cap are disposed on the first end and the second end, respectively, each configured to fit with a socket for a fluorescent light tube. A power supply circuit is configured to provide power to the plurality of LEDs. The plurality of LEDs are arranged to emit light through the elongate light-transmissive cover and at least a portion of the power supply circuit is packaged inside at least one of the end caps.
