A lighting fixture includes a housing, light source, reflector, tandem lens array, shutter blade, and condenser. The housing includes an outlet. An optical axis extends centrally through the outlet. The light source includes an array of light-emitting diodes. The reflector has an input end positioned along the optical axis between the light source and the outlet. The reflector has an output end positioned along the optical axis between the input end and the outlet. The light source emits light from the input end through the output end. The tandem lens array is positioned along the optical axis between the output end and the outlet. The shutter blade is positioned along the optical axis between the tandem lens array and the outlet. The shutter blade is disposed at least partially within the housing. The condenser, including a lens, is positioned along the optical axis between the shutter blade and the outlet.

A sliding lamp includes a base having an electric conductive unit, a driving mechanism disposed on the base, and a slider having a light source and a light emitting area for emitting light out. The slider is disposed on the base in a way that the driving mechanism is capable of driving the slider to slide between a closed position and a wide-open position. When the slider is at the closed position, the light emitting area is completely covered and the light source is electrically disconnected from the electric conductive unit. In the process that the slider slides from the closed position to the wide-open position, the light source is electrically connected with the electric conductive unit and the light emitting area is gradually exposed. Therefore, the sliding lamp is turned on/off or adjusted in brightness by sliding and thereby changed in shape thereof at the same time.

A flashlight includes a light assembly at a first end of the flashlight. The light assembly includes an LED light generating module. The flashlight also includes a power assembly having a power management module body member which houses a charging input port, a USB output port, a LED power indicator, or a power indicator button. A selectively movable sleeve covers the charging input port, the USB output port, the LED power indicator, or the power indicator button when they are not in use, wherein the sleeve moves relative to the power management module body member in linear and rotational directions. The flashlight also includes a central body member between the light assembly and the power assembly.

The invention discloses a spot adjustment subassembly for projection lamp, comprising a light shielding plate located at an light exit end of the light source assembly to block light, and a positioning member for limiting a deflection of the light shielding plate, the positioning member is disposed on the light exit end surface of the light source assembly or on the light incident end surface of the lens imaging assembly, abuts the light shielding plate and applies pressure to the light shielding plate toward the direction of the light incident end surface of the lens imaging assembly or the light exit end surface of the light source assembly. The invention has the advantages of improving the adjustment range of light spot, changing imaging shape and clear imaging.

Disclosed is an LED light source automated luminaire with a multi sided elongated light collimator/mixer/integrator with receiving lens and output lens both with spill shields and where the receiving spill shield is nesting in the output spill shield. The elongated integrator has a square input cross-section and a hexagon or octagon output cross section and is tapered so that the input cross section is smaller than the output cross section.

An arrangement (10) for generating a light effect (26) includes an obscuration sheet material (11) and a divergence sheet material (12) arranged in spaced apart relation to a rear side (23) of an effect sheet material (13). The obscuration sheet material (11) has at least one transmission region (17) and at least one shielding region (18). On the light entry side (15), which faces away from the effect sheet material (13), light (L) impinges on the obscuration sheet material (11) and is severely reduced or completely shielded in shielding region (18), while light (L) passes through the at least one transmission region (17). By means of the divergence sheet material (12), divergent light rays (LD) are produced at the corresponding transmission region (17), which divergent light rays impinge on the rear side (23) of the effect sheet material (13) and generate a light effect (26) for a viewer (25) looking at the viewing side (24).

A lamp, including: a plate, material thereof being optically transparent, the plate including two parallel surfaces and at least one rough width surface for illuminating outside the lamp; a plurality of illuminating sources disposed adjacent and along at least another width surface of the plate; and a user-movable shutter, for covering any of the plurality of illuminating sources, thereby the at least one rough width surface is uniformly illuminated, and thereby moving of the shutter adjusts intensity of the uniform illumination.

A luminaire includes a mixing chamber having an array of apertures in one wall, a light source to supply light into the mixing chamber, and an array of optics outside the mixing chamber, each positioned to cooperate with a respective one of the apertures to emit light from the mixing chamber as a beam. The shape, size, and/or direction of the output light beam are controllably varied by controlling the shape, size, and/or position of each aperture relative to its associated optic.

A lighting fixture comprising a light source, an exit lens and an XY beam manipulating system is disclosed. The XY beam manipulating system is arranged along an optical axis of the lighting fixture between the light source and an outer surface of the exit lens. The XY beam manipulating system is configured to perform movements within a plane and with two degrees of freedom, thereby causing an exiting light beam of the lighting fixture to move in accordance with a selected movement pattern.
