A lighting apparatus comprising a light source which emits light with predetermined light distribution in a fixed direction, and an optical element which is arranged in such a manner that at least part of light emitted from the light source inputs to the optical element, and can perform switching to a transmission state in which the light is transmitted, a first reflection state in which the light is reflected in a first direction, and a second reflection state in which the light is reflected in a second direction different from the first direction.

An illuminated slackline is made of an elongate tube which is formed by a translucent wall. The tube is longitudinally elastic and defines an elongate enclosed space. An elongate light emitting device within the enclosed space emits light which travels through the tube wall and illuminates the slackline. A power cord extends from the device through a slackline terminal securement loop to a power source/lighting power control device which powers and controls the intensity, color and frequency of the emitted light. A friction reducing translucent tube around the device allows the device to slide within the tube elongate enclosed space. A power cord tension relief device in the enclosed space expands to prevent tension on the power cord. Tension in the device and the power cord is thereby prevented as the elongate tube longitudinally expands relative to the device and power cord.

A hanger bar assembly includes a first hanger bar member and a first attachment head coupled to the first hanger bar member by a first coupling segment that is horizontally offset from the first hanger bar member. The hanger bar assembly further includes a second hanger bar member and a second attachment head coupled to the second hanger bar member by a second coupling segment. The first hanger bar member and the second hanger bar member are designed to interlock with each other. An end portion of the first hanger bar member is designed to extend past the second attachment head, and an end portion of the second hanger bar member is designed to extend past the first attachment head through a gap that is between the first hanger bar member and first attachment head.

A disinfection chamber for disinfecting objects placed within an interior space of the disinfection chamber. The chamber includes a plurality of LED fixtures and one or more shelves. The LED fixtures each comprise LED ultraviolet sources and at least one LED visible light source. The ultraviolet sources are configured to emit germicidal ultraviolet light. Each of the shelves comprise a grill frame configured to support and position objects. A first shelf of the one or more shelves is positioned at or near a floor of the interior space. A first LED fixture is positioned upon the first shelf and beneath the grill frame. A second LED fixture is positioned at or near a ceiling of the interior space. The first and second LED fixtures are arranged within the interior space, such that objects placed within the interior space will be disinfected by the ultraviolet sources.

A lighting apparatus equipped with an assembly and support system based on a chain device which allows obtaining the lighting apparatus in various shapes and sizes. The chain device comprises a plurality of links adapted to be together or separated and put on site in an easy and quick manner. Said links may comprise the external protective elements which may be applied to give the link and the chain device a greater strength when assembled to form the lighting apparatus.

An LED lighting array for illuminating an area with the lighting array comprising a plurality of LED devices set in conical or elliptically conical reflectors, each of which is mounted upon a plate, each of which may be set at various angles to one other, and each of which is backed by a series of elements, first a copper support element, then an optional layer of graphite foam, followed by an aluminum plate, and then an arrangement of copper fins operably lined to a thermal mass mate. The copper support element includes support planes that are off-set relative to each adjacent plate and are in at least three different planes relative to each other. The backing plates may efficiently dissipate heat produced by the LEDs. The apparatus can be mounted upon a stand to illuminate an area such as a portion of a car park, building entrance or the like.

A luminaire having a substantially two-piece housing with a first portion and a second portion, for example a cover and a base. The cover receives one or more control components. The base receives a light emitter assembly and the control component assembly is operatively connected to the lighter emitter assembly to control the light output therefrom. A lens assembly can be connected to the bottom of the base 14. Different mounting components can be connected to cover to connect the luminaire 10 to a support.

A flashlight for use with a pistol, the pistol having a trigger guard and a mounting rail. The flashlight includes an elongated housing having a clamping mechanism for mounting to the mounting rail, a light source at one end thereof, and paddle switches at an opposing end.

An optical device includes: a plurality of walls including at least a first wall and a second wall, wherein the plurality of walls are concentrically disposed around a first axis so as to be multi-stepped along the first axis, wherein each of the plurality of walls expands outward in a sector shape around the first axis at a predetermined central angle θ and includes an outer circumferential surface, a reflective curved surface at the outer circumferential surface, a first side end portion, and a second side end portion; a first reflective surface meeting the first side end portions of the walls; and a second reflective surface meeting the second side end portions of the walls. The first reflective surface and the second reflective surface meet each other on the first axis.

Assembly system for attaching a lamp, in particular for attaching an electric cabinet lamp to an electric cabinet, comprising a support structure for the attachment of a lamp, and an attachment device for attaching a lamp to the support structure, wherein the support structure comprises a plurality of shaped elements, wherein the attachment device comprises at least two attaching elements for the connection with at least two shaped elements of the support structure, and wherein at least one of the attaching elements is movable relative to the other attaching element for the tool-free engagement of one of the shaped elements.
