An optic for aisle lighting includes a portion of an optical material defined by a length and a cross-sectional profile. The cross-sectional profile is characterized by a cavity within the optical material, two upwardly-facing surfaces of the optical material on opposite sides of the cavity from one another, and downwardly-facing surfaces of the optical material. The cavity is bounded by an upward facing aperture, and at least three faces of the optical material that meet at interior angles. Light received through the upward facing aperture is separated at the interior angles, and refracted by the faces of the optical material, into separate light beams equal in number to the faces. The two upwardly-facing surfaces internally reflect the separate light beams downwardly. The downwardly-facing surfaces intercept respective portions of the separate light beams, and refract the portions as they exit the optic.

An improved elevated structure-mounted lighting system is disclosed. The lighting system may be used on drilling rigs, or with other applications, including for drilling, production, refineries, frac sites, construction, and other industrial applications that may use tower/mast type equipment. The improved elevated structure-mounted lighting system may accommodate any style or design of crown section of a drilling rig and may be mounted on a pole or independent mount system.

A user can replace a battery smoothly. A portable lighting apparatus includes a guide pipe, a pole supported on the guide pipe in a manner movable in a vertical direction parallel to a central axis of the guide pipe, at least one light emitter at an upper end of the pole, a collar surrounding the guide pipe, a plurality of legs pivotally connected to the collar, and a battery mount located in an upper part of the guide pipe.

Disclosed are a lamp and a mining lamp The lamp includes a reflector, which is a spherical or bowl-shaped structure, an inner wall of the reflector is provided with a plurality of reflective layers in a honeycomb or scaly shape, each of the plurality of reflective layers includes a row of reflective surfaces arranged in the honeycomb or scaly shape, and all the rows of reflective surfaces are of surface reflection.

A stand light includes a telescoping body having a main center shaft, an extension pole extendable out of the main center shaft, and a sleeve movably supported on the main center shaft. A head assembly is supported by the extension pole and includes a light source. A plurality of legs is pivotally coupled to the body and is movable with the sleeve from a collapsed position to an extended position, in which distal ends of the plurality of legs are moved away from the body. When the plurality of legs is in the collapsed position, side portions of the plurality of legs come together to form a handle configured to be grasped by a user.

A light includes a housing including a front face, a first face, a second face, and a first surface arranged adjacent the first face. A lens is coupled to the front face. A light source is covered by the lens. A power source is configured to provide power to the light source. The first face is angled at a first oblique angle with respect to the front face, the second face is angled at a second oblique angle with respect to the front face, and the first surface is angled at a third oblique angle with respect to the front face. The first face, the second face, and the first surface each define a surface configured to support the light. The first face includes two legs spaced from one another and extending away from the first surface.

A luminaire (1) having a preferably flat light exit region (2) that is surrounded by a rectangular light frame (10), wherein the luminaire frame (10) spans a first plane (E) and has a frame height (H) that is perpendicular to the first plane (E) and, at one of its corners (11), a beveled surface (12) in which a plug contact (30) is arranged, and an electromechanical plug connector for a luminaire of this kind are provided.

A light assembly includes a base, and a first light source supported by the base. The first light source includes a first light emitting diode configured to emit light in a first direction from the base. The light assembly additionally includes a second light source supported by the base, the second light source including a plurality of second light emitting diodes configured to emit light in a second direction from the base. The second light source is obliquely oriented relative to the base. The light assembly additionally includes a diffuser supported by the base, the diffuser extending upwardly from the base to enclose the first light source. The diffuser diffuses light emitted from the first light source to the surrounding area in an upward and outward direction.

An optical projection device for projecting a linear image is disclosed. Light emitted by an array of light emitting diodes arranged along an array axis is focused in at least a direction perpendicular to the array axis and diffused in a direction parallel to the array axis, thereby generating a linear image in which light from adjacent light emitting diodes is spatially overlapped. In some embodiments, the focusing and diffusion of the light is performed by a Fresnel lens and a lenticular lens, respectively. The optical projection device may be employed to virtually mark a surface, such as a floor in an industrial setting. High power light emitting diodes may be employed to generate a linear image having an illuminance of at least 4000 lux that is focused to a distance between 7.5 and 20 feet.
