An LED-based tube light suitable for replacing a conventional 48-inch fluorescent tube light includes LEDs connected into a complete illumination circuit that runs exclusively through connectors at one end of the light. In an alternative embodiment, two LED groups are used, each group being connected exclusively to its own set of end connectors.
1. An LED-based tube light for replacing a conventional fluorescent tube light in a fixture designed to receive a conventional tube with bi-pin connectors at each end comprising: a tubular body having opposite ends;a first group of LEDs disposed within said body and connected into a first circuit;a
1. An LED-based tube light for replacing a conventional fluorescent tube light in a fixture designed to receive a conventional tube with bi-pin connectors at each end comprising: a tubular body having opposite ends;a first group of LEDs disposed within said body and connected into a first circuit;a first set of connector pins at one of said opposite ends and connected exclusively into said first circuit;a second group of LEDs disposed within said body and connected into a second circuit; anda second set of connector pins at the other of said opposite ends and connected exclusively into said second circuit;wherein said first and second circuits are electrically isolated from one another. 2. A light as defined in claim 1 wherein said body includes a translucent envelope. 3. A light as defined in claim 1 wherein each of said first and second circuits includes a PWM regulator. 4. A light as defined in claim 1 wherein each of said first and second circuits includes a switch. 5. A light as defined in claim 1 wherein said body is approximately 48 inches long.
