A light emitting apparatus includes a light source, a unitary formed heat sink with a plurality of heat dissipating fins, a lensed enclosure that retains a light source and at least one power consuming device other than the light source. The lensed enclosure includes a recessed opening having at least a first wall that terminates at a substantially perpendicular second wall. The plurality of heat dissipating fins are disposed on at least one adjacent exterior side of the walled enclosure, the fins extending outwardly. At least one fin coupled to the heat sink extends beyond the light source, and the heat generated by the light source travels by conduction laterally through the heat sink to the at least one coupled fin.

A light source includes a plurality of light emitting diodes, with at least some light emitting diodes sized between 30 microns and 500 microns. A plurality of micro-optics are associated with a light guide plate and sized less than 1 millimeter, with each micro-optic positioned over at least one of the plurality of light emitting diodes. At least some of the combinations of light emitting diode and micro-optics associated with the light guide plate are positioned within a distance to each other sufficient to provide a substantially uniform light beam.

Embodiments may utilize a series of exposed fins, which increase the surface area of the heat sink creating additional air flow. As hotter air rises within the system, cooler is drawn into the heatsink. The fins may be exposed on both sides of the longitudinal axis, allowing cooler air to be drawn towards the longitudinal axis above the heatsink and flow upward. This process may cool the fins. Additionally, the spacing between the fins may have to be wide enough to allow for air to freely enter the heatsink.

A rail nut spacer is shown and described, and may have a body and one or more threaded inserts positioned along a width of the body. Threaded inserts may be retained within the rail nut spacer by surface characteristics on each insert to prevent movement thereof with respect to the rail nut spacer. The rail nut spacer may be inserted in a first direction into a slot extending through a width of a housing, such that the slot prevents movement of the rail nut spacer in a second direction. Fasteners may extend through a bezel, through the slot, and/or through the threaded inserts to secure the bezel to the rail nut spacer. The bezel may exert a force on a media to secure the media to the housing. The bezel, media, and/or housing may be sealed together by a gasket to protect an interior of the housing from contaminants.

A lighting fixture is provided. The lighting fixture includes a lamp body, a light source component and an optical element; the lamp body and the optical element form a closed cavity, the light source component is accommodated in the closed cavity; the light source component includes a light source substrate and a light emitting unit located on a front surface of the light source substrate, and the optical element is located in a light emission direction of the light emitting unit; the light source substrate includes a back surface facing away from the front surface, the lamp body is formed with a heat dissipation structure, and the heat dissipation structure is in contact with the back surface of the light source substrate. The lighting fixture provided by the present disclosure has good heat dissipation performance.
