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 or the derrick of a drilling rig and may be mounted on a pole or independent mount system.

A high bay light fixture (100) comprising multiple heat sink structures (102, 104, 106, 108) attached to an electronics housing (110), and light sources (132, 134, 136, 138) attached to the multiple heat sink structures (102, 104, 106, 108). Each heat sink structure (102, 104, 106, 108) includes a bottom wall (202) and side walls (204, 206, 208, 210) that extend up from the bottom wall (202). Each light source (132, 134, 136, 138) is attached to the bottom wall (202) of a respective heat sink structure (102, 104, 106, 108) on a surface of the bottom wall (202) facing away from the electronics housing (110). Each heat sink structure (102, 104, 106, 108) is spaced from other heat sink structures of the multiple heat sink structures (102, 104, 106, 108) that are adjacent to the heat sink structure (102, 104, 106, 108).

A lighting device includes a light housing, a light source coupled to the light housing, and a battery compartment coupled to the light housing and configured to house a battery. The battery compartment defines a central longitudinal axis along which the battery is insertable. The lighting device additionally includes a base coupled to the light housing. The light housing and the battery compartment are rotatable together relative to the base about the central longitudinal axis.

The present invention discloses an intelligent induction miner's lamp. A heat dissipating portion in the miner's lamp includes a substrate, a reflector, and heat sinks; the substrate provided with a first through-hole in the center thereof is arranged on an inner wall of the reflector; an upper surface of the substrate is provided with a plurality of the heat sinks; the substrate, the reflector, and the heat sinks are integrated during casting; the power source cover is provided with a latching switch and is arranged on the reflector; the reflector is provided with a lens whose center is a recessed blind via; the lens is located on a side of a lower surface of the substrate, a ring protrusion is provided around the recessed blind via, and a sensor is arranged in the recessed blind via; the lens, the reflector, and the power source cover form a cavity; a driving power source fixed to the substrate is arranged in the cavity; and the lower surface of the substrate is provided with a light emitting element corresponding to the ring protrusion. In the present invention, the latching switch is arranged on the power source cover. Before the miner's lamp is mounted, whether the miner's lamp has a sensing function can be controlled by using the latching switch. In this way, use of other lamps of the same type is not affected, the costs are low, and mounting, cable layout, and subsequent maintenance are easy.

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.

A handheld clamp work light is disclosed having a light member, a housing member for movement of the light member, a handle member having a handle housing and a clamp member, and the handle housing and the clamp member include feet members which pivot and may be attached to an object.

A light includes a housing having a top face, a bottom face, a first side face, a second side face, and a surface arranged adjacent to the bottom face. The top face, the bottom face, the first side face, the second side face, and the surface are each configured to support the light. The light further includes a head pivotally coupled to the housing. The head includes a lens and a plurality of LEDs configured to emit light through the lens. The light additionally includes a power source configured to provide power to the plurality of LEDs. The head is positioned between the top face, the bottom face, and the first and second side faces in a first position of the head. The surface is obliquely oriented relative to the lens when the head is in the first position.

One or more reduced, same form, light emitting apparatus(es) spaced apart and configured to be mounted at various heights and/or spacing employ the same power consuming light source input that is covered by a symmetrical or asymmetrical redirecting linear lens optics apparatus that is configured for use in a range of mounting heights to uniformly illuminate at least one legal path of egress below.
