Abstract: A lighting fixture includes a first housing portion and a second housing portion. The first housing portion includes a base and a wall extending outwardly from substantially the perimeter of the base. A top portion of the wall includes one or more hinges extending outwardly therefrom. The second housing portion includes a front panel and a side panel extending outwardly from substantially the perimeter of the front panel. A top portion of the front panel includes at least one slot. The second housing is coupled to the first housing in an open position when the hinge is inserted into the slot and the front panel is disposed elevationally above the base. The second housing is coupled to the first housing in an operational position when the hinge is inserted into the slot and the front panel covers the base.

Abstract: A shrouded impeller and a method of additively manufacturing the same are provided. In one example aspect, the shrouded impeller includes a hub and a shroud spaced from the hub. The shrouded impeller also includes a plurality of vanes extending between and connecting the hub and the shroud. The vanes are spaced circumferentially apart from one another. Flow passages are defined between adjacent vanes. In some implementations, the shrouded impeller is additively manufactured. During printing, one or more support structures are formed within and fill a portion of one or more of the flow passages to support the unsupported walls of the shrouded impeller, e.g., the shroud. Further, the support structures are removable from the shrouded impeller, e.g., after the shrouded impeller has been printed.

Abstract: A lighting fixture structure for a suspended lighting fixture includes an electronics housing for containing lighting electronics. The lighting fixture structure further includes a thermal barrier positioned around a portion of the electronics housing. The lighting fixture structure also includes a heat sink. The electronics housing is separated from the thermal barrier by a first air gap, and the thermal barrier is separated from the heat sink by a second air gap.

Abstract: A modular lighting system may include a support structure, a plurality of heat sink modules physically supported by the support structure, and one or more light source modules coupled to the plurality of heat sink modules. The plurality of heat sink modules may be arranged in a modular manner such that the number of heat sink modules in the modular lighting system is variable, and each heat sink module may be an integral molded structure defining at least one opening or passageway.

Abstract: A light fixture assembly includes a light fixture and one or more reflectors having a curved cross-sectional profile. The light fixture includes a housing that is configured to house one or more electrical components of the light fixture. Further, the light fixture includes a heat sink that is coupled to the housing, and a plurality of light sources coupled to a bottom surface of the heat sink such that they emit light in a first direction. At least one of the one or more reflectors is coupled to the heat sink and disposed in the first direction of at least a portion of the plurality LEDs such that the light emitted by the portion of the plurality of LEDs is reflected by a substantially concave shaped inner surface of the respective reflector towards a second direction that is substantially opposite to the first direction.
