20100254134 | Light Fixture - Light fixtures having a plurality of light-emitting diodes that maximize the amount of direct light into an intended area. The light fixture may include a carriage with a first (top) end and a second (bottom) end. A hood may be mounted to the first end of the carriage. At least one light engine comprising a plurality of light sources is mounted to the hood. The light sources emit light downwardly directly onto an intended area. In certain embodiments the second end of the carriage is shaped and sized so that it does not interfere with emission of the light to the intended area. The light fixture thus provides light in a thermally efficient manner, maximizes the amount of direct light, and limits the amount of light pollution. | 10-07-2010 |

In certain embodiments, the light fixture includes a housing, a light source, and a bracket. Set of fins may protrude from the housing, and flanges may protrude from the bracket. In use, the flanges engage ribs on the housing to support the lighting fixture. By altering the engagement between the flanges and ribs, the light fixture may be re-positioned within the bracket in a number of different orientations, creating a number of light distribution options for the light fixture. | 10-07-2010 |
20110310625 | Light Fixtures Comprising Organic Light Emitting Diodes - Light fixtures comprising an organic light emitting diode (OLED) as the light source, and further comprising a housing, at least one hollow, and an optic. The at least one hollow defines an intended area where light is emitted, and includes a reflective surface to reflect light within the intended area. The optic comprises a refractive portion that is defined by two edges. In one embodiment, the OLED is coupled to the two edges of the optic. In another embodiment, the OLED is coupled to and contacts an inner surface of the refractive portion. In either embodiment, the OLED is either sufficiently close to or contacting the refractive portion such that surface area of emitted light is maximized. Additionally, the OLED is placed sufficiently close to (or within) the intended area that reflected light and optical efficiency are maximized. | 12-22-2011 |

20090091271 | Lighting Assemblies for Vending Machines - Display cases having lighting assemblies and methods of illuminating display cases with such lighting assemblies. Embodiments of the lighting assemblies may be used in display cases of any type and particularly in those where the purchaser selects via an external mechanism (e.g., buttons) a product from a variety of products stored inside the display, such as a vending machine. Lighting assemblies are installed within a vending machine, such as on or within the vending machine shelves or product dividers, and their light emission controlled depending on the product being selected from the vending machine. In on embodiment, all light sources within the vending machine except those illuminating the selected product are dimmed. In this way, the product being selected by the purchaser can be emphasized. In other embodiments, color or multi-color LEDs are used to emit light that best compliments the color of products housed within the vending machine. | 04-09-2009 |
20110286214 | LED LIGHT FIXTURE - Light fixtures for illuminating spaces that use light emitting diode-based light sources and that incorporate chip on board technology that enables the light emitting diode to be mounted directly on a portion of the light fixture. In some embodiments, the light fixture includes a reflector assembly onto which the light emitting diode is directly mounted. In other embodiments, the reflector assembly includes an aperture that receives a board having chip on board technology onto which the light emitting diode is directly mounted. In some embodiments, the light fixture also includes a diffuser for diffusing the light emanating from the light emitting diodes. | 11-24-2011 |
20120314430 | MODULAR HEAT SINK - Modular heat sinks formed by a plurality of interlocked modules. The modules include fins that define channels. In some embodiments, the fins and channels extend along an axis that is not parallel to an axis in which the heat sink extends and/or to a plane in which one of the top or bottom walls of at least one module of the heat sink extends. In some embodiments of the heat sink, the channels extend through the thickness of the heat sink to allow air easily to enter the channels from below and pass through and exit the channels from above to facilitate heat dissipation. | 12-13-2012 |
20140029261 | In-Plane Bent Printed Circuit Boards - In certain embodiments there is provided a blank for a printed circuit board and methods pertaining to same. In some embodiments, the blank is provided in a generally straight configuration and is capable of being deformed in-plane into a bent configuration, such as, but not limited to, a generally ring-shaped configuration, a generally square shape, or a generally S-shape. In some embodiments, the PCB is used with a lighting fixture and is populated with light emitting diodes. | 01-30-2014 |
20140055991 | Printed Circuit Boards with Deformations - 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. | 02-27-2014 |
20140264393 | LIGHT ENGINE - A light engine with a heat sink having a curved recessed cavity that receives a flexed or cupped PCB bearing a plurality of LEDs. Once situated within the cavity and released, the PCB has a tendency to return to its flat state, but flanges or other suitable mechanisms at the ends of the cavity restrain the edges of the PCB and prevent the PCB from returning to its flat state. In this way, the PCB is securely retained within and biased against the cavity by its own forces. As the PCB heats, the PCB expands, further biasing the PCB against the cavity of the heat sink and increasing the thermal conductivity between the two components. | 09-18-2014 |

20110006067 | ONE-PIECE WATER METER PIT FRAME - A water meter pit assembly includes a roto-molded frame to be supported by a meter pit column. The meter pit frame comprises a one-piece component having a base portion to be supported on the meter pit column and a top portion to be releasably secured to the frame so that the plastic cover can be detached when needed to provide access to water meter components that are located within the water meter pit. | 01-13-2011 |
20120067753 | SHARPS CONTAINER - A sharps container includes a sub-lid that normally defines an opening into the container that is too small for a hand. Upon closure of the sub-lid, the opening is enlarged so that larger objects can be placed in the container while the closure of the sub-lid continues to prevent a hand from reaching into the container interior. Other embodiments are also disclosed. | 03-22-2012 |

An outer rib projects downward from an outer edge of each of the feet such that the side drag rail of an identical upper tray being stacked on the bakery tray contacts the flanges while the outer ribs of the upper tray are received between the outer side rail and the inner side rail. In another feature, the side walls include handle openings, the handle openings each partially defined by a convex outer wall. In another feature, an upper edge of the front wall includes finger corrugations for accommodating the fingers of a user's hand grasping the tray. | 08-23-2012 |
