A method for example of irradiating a light-curable material, may comprise irradiating light about a first axis from an array of light-emitting elements towards a light-curable surface, directing the irradiated light through an optical element interposed between the array of light-emitting elements and the light-curable surface, wherein a central axis of the optical element is offset from the first axis, and deflecting the irradiated light directed through the optical element asymmetrically away from the first axis towards the light-curable surface.

A retrofit LED lamp assembly and retrofitting method for use in a vending machine. The retrofit LED assembly having a plurality of light emitting diodes (LEDs) and a power connector adapted to connect to a source of power within a vending machine. A power regulating circuit adjustably controls the amount of power provided to the LEDs in response to control signals received by a communication circuit in the lamp assembly.

A flap mechanism (2) has a housing (10), a flap aperture (21) formed on the housing (10), and a flap element (20) that at least partially closes the flap aperture (21) in a closed position and can be transferred from the closed position to an open position for at least partially freeing the flap aperture. The flap element (20), in the open position, protrudes at least with an end portion (200) from the housing (10). At least one light element (22) is arranged on the flap element (20) and generates a gleam of light on the end portion (200) of the flap element (20) at least in the open position of the flap element (20).

An illuminating device for indoor lighting comprising a visible panel, through which light can be transmitted. The visible panel includes a portion having transparent material, and a panel retaining device. The retaining device has a retaining means for retaining the visible panel and a fixing means for mounting the visible panel on a ceiling or on a wall. The retaining device has at least three interconnected retaining arms which are arranged in the shape of a star and which retain at least two visible panel parts at the inner faces of the visible panel parts, the inner faces of the visible panel parts bordering each other such that said visible panel parts together form a substantially continuous visible panel surface. The visible panel parts have free outer faces which are not retained by the retaining arms and which together from the outer circumference of the visible panel.

A light tower assembly for the high density illumination of an indoor or outdoor area by a portable power plant or a stationary power source includes at least one vertical support shaft, at least one cross member attached to the vertical support shaft and at least on omnidirectional heavy duty LED light bracket attached to the cross member, providing support to a high lumen LED light, with the heavy duty LED light bracket being moveably aimed within a range of 360 degrees from a pivotal mounting point on the cross member.

A lighting system for a drilling rig including a lighting frame attached to a crown of the drilling rig, wherein the lighting frame includes an adjustable frame portion attached to the crown of the drilling rig and a light bearing frame portion supported by the adjustable frame portion. Also provided is at least one light support post attached to the light bearing frame portion for holding a lighting fixture and at least one lighting fixture attached to each light support post.

A system that can include a crown deck with a handrail positioned along an outer perimeter, a support structure mounted to the crown deck, where the support structure can horizontal supports rigidly attached to vertical supports, the horizontal supports being supported at a vertical elevation above the crown deck by the vertical supports, which are welded to a top surface of the crown deck, with light fixture assemblies mounted to the horizontal supports, with each one of the light fixture assemblies being rotatable, relative to the horizontal supports, between a stowed position and a deployed position, where the stowed position locates a respective one of the light fixture assemblies radially spaced away from the outer perimeter of the crown deck and toward a center of the crown deck.

A housing assembly for an electronic device, including a connection side on which at least one connection is provided, a first longitudinal side, a second longitudinal side, a first front side, and a second front side. The sides each have at least one housing wall. The housing assembly has at least two indicator lights having one luminous area. The luminous areas are arranged so as to be distributed along the housing assembly such that in an activated state, the luminous areas together emit light signals at least into a hemispherical region around the housing assembly. An electronic device is furthermore described.

A system that can include a crown deck with a handrail positioned along an outer perimeter, a support structure mounted to the crown deck, where the support structure can horizontal supports rigidly attached to vertical supports, the horizontal supports being supported at a vertical elevation above the crown deck by the vertical supports, which are welded to a top surface of the crown deck, with light fixture assemblies mounted to the horizontal supports, with each one of the light fixture assemblies being rotatable, relative to the horizontal supports, between a stowed position and a deployed position, where the stowed position locates a respective one of the light fixture assemblies radially spaced away from the outer perimeter of the crown deck and toward a center of the crown deck.

A caulk nozzle lighting system for lighting a nozzle of a caulk cartridge and an adjacent work area includes a caulk gun which has a cartridge holder with a front wall, a back wall, and a perimeter wall. The perimeter wall is coupled to and extends between the front wall and the back wall. The cartridge holder defines a bay for accommodating the caulk cartridge surrounded by the front wall, the back wall, and the perimeter wall. A lighting assembly is mounted to the front wall of the cartridge holder of the caulk gun and is configured to emit light forwardly with respect to the front wall.
