Gobo projection targeting devices have a light source, a lens assembly associated with the light source, the lens assembly having a first element, a second element, and an aiming figure, the first element being closer to the light source, and the second element having a smaller diameter than the first element, such that a first portion of light emitted by the light source and transmitted by the first element will bypass the second element and a second portion of light emitted by the light source and transmitted by the first element will not bypass the second element. The first and second elements may each be converging lenses. The second element may be adapted to generate an image of the aiming figure away from the illuminator. The first portion of light may be a field illumination pattern lacking a focused image. The lens assembly may be movable.

A system for illuminating a surface has at least one lighting means and a housing. At least one lens is disposed within the housing. The at least one lens is supplied with light rays from the lighting means. The at least one lens for illuminating the surface is exchangeable.

In an aspect, a lighting system (1) comprises a lighting unit (11) with a light source (31) and a dichroic light exiting surface (15), wherein the lighting unit (11) is configured for emitting dichroic light from the dichroic light exiting surface (15). The emitted dichroic light includes a directional light portion (37) of direct light (17) and a diffused light portion (39) of diffused light (19) with a another larger correlated color temperature. The lighting system further comprises an appearance affecting optical system (13) with a plurality of structural elements (40, 91, 93, 101, 105) that comprise surfaces that delimit a plurality of diffused light passages (14, 103, 107), and comprise direct light illuminated surface regions (25), which are subject to the illumination with direct light (17) from respectively associated affected direct light providing areas (81) of the dichroic light exiting surface (15). Moreover, the affected direct light providing areas (81) cover at least 70% of the dichroic light exiting surface (15), and the direct light (17) from at least one affected direct light providing area (81) and diffused light (19) propagate within at least one of the diffused light passages (14, 103, 107).

An LED light fixture is disclosed with an elongated housing that forms a open lower light channel and an upper light channel that is juxtaposed to the open lower light channel with electronics cavity or conduit positioned there between. The LED light fixture preferably has an elongated reflective insert that extends through the open lower light channel and creates a reflection channel from which the indirect and reflected light is emitted and a detachable cover structure that includes a diffusion lens and a removable baffle structure that attaches to side walls of the upper light channel.

The invention provides a ceiling mounting structure, comprising a hanging board, at least one connector and at least one guide rail of which the quantity corresponds to that of the connector, wherein one end of the hanging board is articulated with one end of the connector, and the other end of the hanging board is provided with first clamping hooks; the guide rail has one end provided with rail-type clamping hooks and the other end is provided with second clamping hooks; the connector has hook grooves; the hanging board is fixed on a ceiling; the hook grooves and the rail-type clamping hooks form rail-type sliding and are connected with in a hooking way; and the first clamping hooks and the second clamping hooks are connected in a snap-fit way.

Firearm aiming illuminators have a frame, a light source, a lens assembly associated with the light source, the lens assembly operable to generate a broad illumination field and to project an aiming point on a target, and the lens assembly having an aiming facility adjustably connecting the lens assembly to the frame and operable to adjust the position of the aiming point relative to the frame. The adjustment facility may include a ball and socket mechanism with the ball on the lens assembly and the frame defining a socket. The adjustment facility may include a pair of first and set screws connected to the frame and operably contacting the lens assembly, each set screw associated with a different aiming axis. The set screws may each define a respective rotation axis, and the rotation axes may be parallel to each other.
