Abstract: An LED lamp includes an elongated at least partially optically transmissive enclosure. The LEDs are mounted on an LED board. The enclosure has a support structure for supporting the LED board. The support structure is formed as one-piece with the enclosure and of an optical material. A pair of end caps are secured to the ends of the enclosure using a snap-fit connection. The end caps retain pins for connecting to a light fixture.

Abstract: A LED lamp includes an elongated at least partially optically transmissive enclosure having a first end and a second end. LEDs are in the enclosure and are operable to emit light through the enclosure when energized through an electrical path. A first pin is mounted to the first end of the enclosure and a second pin mounted to the second end of the enclosure, the first pin and the second pin are in the electrical path. The LEDs are mounted on an LED board. A plurality of discrete braces are spaced along the length of the LED board and are mounted to the LED board. The braces support and position the LED board in the enclosure.

Abstract: An LES is a surface from which light emanates from a lighting fixture. The present disclosure relates to a providing a lighting fixture that has an actual light emitting surface (A-LES), which is substantially smaller than the maximum potential LES (M-LES) for the lighting fixture. The M-LES is defined as the theoretical maximum LES for the mounting structure of the lighting fixture, and the A-LES is defined as the actual LES of the lighting fixture, as dictated by the lens or optical structures of the lighting fixture. The A-LES may provide an LES that is not only smaller, but also shaped differently, from the M-LES, to help control the light output of the lighting fixture based on the lighting application.

Abstract: The present disclosure relates to a lighting fixture that is configured to transfer heat that is generated by a light source and any associated electronics toward the front of the lighting fixture. The lighting fixture includes a heat spreading cup that is formed from a material that efficiently conducts heat and a light source that is coupled inside the heat spreading cup. The heat spreading cup has a bottom panel, a rim, and at least one sidewall extending between the bottom panel and the rim. The light source is coupled inside the heat spreading cup to the bottom panel and configured to emit light in a forward direction through an opening formed by the rim. Heat generated by the light source during operation is transferred radially outward along the bottom panel and in a forward direction along the at least one sidewall toward the rim of the heat spreading cup.

Abstract: An enclosure is divided into first and second portions by a theoretical plane defined by a horizontal line. LEDs are mounted on an LED board in the enclosure and are operable to emit light when energized through an electrical path. A first pin is mounted to a first end of the enclosure and a second pin mounted to a second end of the enclosure, both pins being in the electrical path. Braces support the LED board and comprise first and second legs. The first leg and second leg extend to a first point and a second point of intersection of the plane and the internal surface of the enclosure, respectively. A first conductor connects the first pin to the LED board and a second conductor connects the second pin to the LED board. The first conductor and first pin and the second conductor and the second pin are one-piece.
