A luminaire includes a lamp barrel having a light source detachably connected with a lens assembly. The lens assembly includes a lens barrel detachably connected with the lamp barrel and a focusing member on the lens barrel. An adjusting assembly includes a rotatable focusing ring, a lens fixing ring and a lens. The focusing ring includes a spiral groove on an inner surface. The lens fixing ring includes a projected rail on an outer surface. The lens barrel includes a bar shaped through hole extending along an axial direction. The projected rail passes through the bar shaped through hole and is mated with the spiral groove by clearance fit. Rotation of the focusing ring acts on the projected rail through the spiral groove and drives the lens fixing ring and the lens forward and backward in the lens barrel to adjust a distance between the lens and the light source.

A beam shading device capable of accurately positioning includes a substrate, a plurality of shading blades mounted on the substrate, and driving mechanisms for driving the shading blades to move. The substrate is provided with a first light-passing hole through which beams pass, the plurality of shading blades are arranged around the periphery of the first light-passing hole, and the driving mechanisms drive the shading blades to move back and forth between blocking and opening the first light-passing hole. Each shading blade is configured with at least two driving mechanisms, and each driving mechanism includes a driving gear and a driving plate. The driving plate is hinged with the shading blade, and the driving plate is provided with a rack that meshes with the driving gear.

A lighting apparatus including a base is provided. The base includes a through-hole. The through-hole is aligned with an optical path of laser light for receiving and transmitting the laser light. A light emitter which, when irradiated with the laser light transmitted through the through-hole, radiates light by converting a wavelength of the laser light. An attachment component is provided on the base for attachment of the light emitter to the base. The light emitter is removable from the base. A light blocker opens the optical path of the laser light by being contacted by the light emitter when the light emitter is attached to the base, and blocks the optical path of the laser light when the light emitter is removed from the base.

A device and the method of installing and adjusting same, which provides reduction of glare from overhead lighting, including but not limited to “can” lighting, also referred to as recessed lighting.

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.

A light output reducing shutter system, having a light system with a shutter barrel assembly, a solid shutter assembly, a first translucent shutter assembly, and a second translucent shutter assembly, wherein the solid shutter assembly, the first translucent shutter assembly, and the second translucent shutter assembly are positioned in a same focal plane when a light is projected from the light system. The first translucent shutter assembly has a first degree of translucency and the second translucent shutter assembly has a second degree of translucency. The shutter barrel assembly has a first set of slots, a second set of slots, and a third set of slots to receive the solid shutter assembly, the first translucent shutter assembly, and the second translucent shutter assembly respectively. The first set of slots, the second set of slots, and the third set of slots each have four slots around the shutter barrel assembly.

A stage light free from damage of sunlight includes a light body and a control assembly, and a light avoiding system. When the light body is in a power-on state, the control assembly controls the light avoiding system not to work; and when the light body is in a power-off state, the control assembly controls the light avoiding system to implement a light avoiding action. According to the present invention, smart light avoiding according to a sunlight status can be achieved by means of a light avoiding system. The light avoiding system has advantages of a high automatic recognition level, a flexible access system, and being cost-effective and easy to implement.

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.
