Abstract
An LED-based light for replacing a conventional fluorescent tube in a fixture is provided. The LED-based light includes an elongate light transmitting rod defining a bore and at least one LED positioned at one or both ends of the rod and oriented to produce light longitudinally into a portion of the rod radially outward of the bore. At least one connector is physically coupled to an end of the rod and electrically coupled to the at least one LED. The at least one connector is adapted for physical and electrical connection to the fixture. In operation, the directional light produced by the at least one LED is dispersed by way of reflection, refraction, and/or diffusion while traveling longitudinally through the rod to reduce the appearance of bright spots.
