Abstract
A light modifier for an LED producing light about a central axis is provided. The light modifier includes a lens defining an indentation. The indentation is angled relative to the central axis by an amount less than a complementary angle of a critical angle of the lens along the indentation. The lens can reduce the appearance of a bright spot created by the LED.

13. A replacement light for a fluorescent tube usable in a fluorescent fixture comprising:
-
a support structure having a longitudinal axis; at least one LED connected to the support structure, the LED producing light about respective central axes; at least one lens positioned along the central axis of the at least one LED, the lens defining an indentation angled relative to the central axis less than a complementary angle of a critical angle of the lens along the indentation; and at least one electrical connector at a longitudinal end of the support structure in electrical communication with the at least one LED. - View Dependent Claims (14, 15, 16, 17, 18, 19, 20, 21, 22, 23, 24, 25, 26, 27, 28, 29)

30. A method of forming a lens for an LED producing light about a central axis, the lens defining an indentation angled relative to the central axis less than a complementary angle of a critical angle of the lens along the indentation, the method comprising:
-
extruding material in an extrusion direction to form a sheet of greater width than the lens, the sheet having a same profile as the lens; and sectioning the sheet to form the lens. - View Dependent Claims (31)

32. A replacement light for a fluorescent tube usable in a fluorescent fixture comprising:
-
a support structure having a longitudinal axis; multiple LEDs connected to the support structure, the LEDs producing light about respective central axes; at least one light pipe positioned along the central axis of one of the LEDs, the light pipe having a reflector positioned over at least a portion of the LED such that the light initially emitted from the LED strikes the reflector; and at least one electrical connector at a longitudinal end of the support structure in electrical communication with the multiple LEDs.
