Fluorescent tube replacement having longitudinally oriented LEDs
First Claim
1. An LED-based light for replacing a conventional fluorescent tube in a fixture, the LED-based light comprising:
- an elongate light transmitting rod having a first end and an opposing, second end and defining a bore extending at least partially between the first end and the second end, the bore having an outer surface spaced apart from an outer surface of the rod such that a material of the rod fills a portion of the rod between the outer surface of the bore and the outer surface of the rod;
at least one LED positioned at one or both of the first and second ends of the rod and oriented to produce light longitudinally into the portion of the rod radially outward of the outer surface of the bore; and
a connector physically coupled to the first end or the second end of the rod, the connector adapted for physical connection to the fixture.

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.

17. A method of forming an LED-based light for replacing a conventional fluorescent tube in a fixture, the method comprising:
-
providing an elongate light transmitting rod defining a bore, the bore having an outer surface spaced apart from an outer surface of the rod such that a material of the rod fills a portion of the rod between the outer surface of the bore and the outer surface of the rod; positioning at least one LED to produce light longitudinally into the portion of the rod radially outward of the outer surface of the bore; and attaching a pair of bi-pin end caps to opposing ends of the rod, with each of the pair of end caps in physical communication with an opposing mount of the fixture. - View Dependent Claims (18, 19, 20)
