According to an aspect of the present disclosure, a luminaire comprises a plurality of waveguides, a light source arranged to direct light into the plurality of waveguides, and a plurality of extraction feature patterns. The luminaire contemplated by the present disclosure is arranged with the plurality of waveguides are aligned such that an extraction feature pattern extracts light out of a first waveguide of the plurality of waveguides and a second extraction feature pattern extracts light out of a second waveguide of the plurality of waveguides. Further, in accordance with this aspect, the light extracted out of the first waveguide is directed through the second waveguide to develop an appearance of depth.

The present invention relates to a lighting device including a light transmittable shell, a conductive unit and a light source. The light transmittable shell has an inner space and a mounting opening connected to the inner space. The light source is mounted around the mounting opening such that the LEDs in the light source are arranged along the edge of the mounting opening. The light from the light source transmits through the light transmittable shell from the edge of the mounting opening, leading to a glowing effect of the light transmittable shell, improving the lighting efficiency of the lighting device. Furthermore, the LEDs are distributed along the edge of the mounting opening and have direct contact with the flowing air in open space, so the heat-dissipation of the LEDs is effective enough without extra cooling components.

The present disclosure provides a safety light. The safety light includes a top housing; a printed circuit board assembly coupled to the top housing, the printed circuit board assembly having a top surface and a bottom surface; a plurality of light elements coupled to the bottom surface of the printed circuit board assembly, the printed circuit board assembly programmed to energize the plurality of light elements following depression of a first control button; a lens coupled to the bottom surface of the printed circuit board assembly and the plurality of light elements, the lens having a first angled reflective surface and a plurality of side surfaces; and a bottom housing coupled to the lens.

A trellis lighting system that includes at least one lighting and support assembly. The at least one lighting and support may include a cover, a heat sink, and at least one light emitting diode (LED) strip. The cover permits light to pass there through and includes a body extending a first length. The heat sink is configured to couple to the cover and may include a body extending a second length. The body may include an outer surface, an inner surface defining a lumen that extends through the body, a plurality of outer fins coupled to the outer surface, and a plurality of inner fins coupled to the inner surface. The at least one LED strip may be configured to be coupled to the body of the heat sink along the second length thereof so as to dissipate heat generated by the at least one LED strip.

An illumination system includes a light assembly. The light assembly may include a housing having a first zone and a second zone isolated from the first zone. The housing may be configured to fit generally flush with a ceiling. A movable light source may be positioned within the first zone and is configured to emit a first light. A stationary light source may be positioned within the second zone and is configured to emit a second light.

A luminaire configured to emit light in different directions. The luminaire may include a frame and optical waveguides disposed in the frame and positioned at different angles relative to one another to direct light outward in multiple different directions. At least one LED may be associated with each optical waveguide. A shield may be associated with the frame and configured to reduce the light from being directed in one or more of the different directions.

Pursuant to some embodiments, a high mast luminaire includes a driver housing and a light engine assembly comprising a light engine housing which includes a circumferential wall, the light engine housing comprising an interior space in which a plurality of LED light engines are located, wherein the light engine housing includes a plurality of air flow channels on a radially outer side of the wall, and wherein the air flow channels are separated from the plurality of LED light engines by the circumferential wall.

A light fixture for horticultural applications is provided wherein the fixture has a predetermined patent and nonuniform distribution of LEDs. The nonuniform distribution of LEDs forms at least one light cluster that is strategically positioned on the light fixture to greatly reduce or even eliminate light drop off that might otherwise be experienced by plants that are positioned adjacent to the light fixture in the growing environment.

An illuminator includes an upper shell, a lower shell, an LED array and at least one fan. The upper shell includes a first outlet portion extending downward and inward from an inlet portion. The inlet portion includes at least one entrance. The first outlet portion includes a row of vents. The lower shell is made of thermally conductive metal and includes primary radiator fins extending from an upper face of a substrate. The lower shell is connected to the upper shell to form a tubular structure. The LED array is connected to a lower face of the lower shell and includes light-emitting diodes. The at least one fan is inserted in the tubular structure, connected to the inlet portion, and aligned with the at least one aperture.

The present invention relates to an LED strip, comprising a plurality of LEDs mounted on a LED mounting surface of a flat, flexible substrate, wherein said LED mounting surface is light reflective, wherein said flexible substrate is shaped to form at least one conical structure, and wherein a subset of said plurality of LEDs is located inside at least one of the at least one conical structure.
