Abstract: Retention members for securing LED boards to substrates while permitting light from the LEDs to be emitted unobstructed. The present retention members may be in the form of clips that are designed to span an LED board and attach to a substrate so as to trap the LED board between a retention member and the substrate. The retention members described herein may include one or more retention features that may interface with a corresponding mounting feature formed on the substrate to secure the retention member and thus the LED board to a substrate.

Abstract: A shield for a light emitting diode (LED) luminaire includes a frame mountable to the LED luminaire such that the shield is removable therefrom. A plurality of rows of shield surfaces contact the frame and have a first side that faces a row of LEDs located on the LED luminaire and an opposite second side. The first side has a fully or partially reflective surface. The plurality of rows of shield surfaces prevent light from the LEDs from reflecting toward the back of the LED luminaire. The shield may include notches for allowing removal of one or more of the plurality of rows of shield surfaces or a portion thereof from the frame and for customization of light distribution from the LED luminaire. The shield may also be cut lengthwise such that each of the plurality of rows of shield surfaces includes a partial shield surface and shields only a portion of a row of LEDs located on the LED luminaire.

Abstract: Light engines for inclusion in luminaires. Some embodiments of the light engine include a heat sink, a reflector, and light emitting diodes. Some embodiments of the heat sink include perforations. The reflector includes a reflective surface that extends around at least a portion of the light emitting diodes. In some embodiments, a portion of the reflector is sandwiched between the light emitting diodes and the heat sink. In some embodiments, an end of the reflector terminates above the light emitting diodes to reduce the concentration of light directly above the light emitting diodes but rather distribute the light outwardly from the luminaire.

Abstract: A metal core printed circuit board that is mechanically deformed so as to improve the mechanical properties (e.g., improved section modulus or stiffness) of the board. The board is configured to be self-retaining such that it retains the deformation(s) without the help of other support structure. More specifically, the metal layer in the board is plastically (and permanently) deformed so as to retain the deformation(s) in the board.
