Light tube and power supply circuit
First Claim
1. A light fixture comprising:
- a socket;
a first bracket configured to receive a light emitting diode (LED) replacement light tube and secure the LED replacement light tube with respect to the socket; and
a first inductive transmitter configured to receive electrical power from a power source and transmit at least a portion of the electrical power inductively to a first inductive receiver of the LED replacement light tube.

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.
