The at least two regions respectively have different optical properties. The light beam has different brightness after respectively passing through the at least two regions.

A luminaire including an LED light source, a plurality of color filters, an optical device, and a control system is provided. In response to receiving an optical device setting value via a data link, the control system moves the optical device according to the setting value, calculates modified positions for one or more of the color filters based on an effect of the optical device on the color of the light beam of the luminaire, and causes the one or more color filters to move to their modified color filter positions, in order to reduce the effect of the optical device on a beam color emitted by the luminaire.

A luminaire includes an elongated housing having a long axis, a plurality of light emitters extending in a direction of the long axis, a first light shield rotatably coupled to a base of the luminaire and configured to rotate about a first axis parallel to the long axis, and a second light shield rotatably coupled to the base of the luminaire and configured to rotate about a second axis parallel to the long axis. The first light shield and the second light shield are configured to physically couple to form a combined light shield that is configured to block light emitted by the plurality of light emitters.

The present invention relates to the technical field of stage light fixtures, in particular to a stage light fixture having a universal support arm, which includes a supporting arm rotatably supported on a bottom base, the supporting arm having a universal frame of an integrally formed structure and an adapter detachably connected to the universal frame and a light head rotatably disposed at the adapter via a rotating shaft, a light source being disposed in the light head. The present invention is advantageous to improve the mounting accuracy and overall structural strength of the movable support of a light head, simplify the assembly process of the movable support of the light head, and contribute to standardize the production of the movable support of the light head.

A manual control device coupled to a Digital Multiplex (DMX) lighting controller and a moving head spotlight is configured to allow the moving head spotlight to be manually controlled by a manual controller or perform original functionality of the moving head spotlight. The manual control device comprises a manual control box, which is further comprised of a manual controller, a control module having a microcontroller, and a bypass switch. The microcontroller processes DMX signals including a pan coarse signal, a pan fine signal, a tilt coarse signal, and a tilt fine signal from the DMX light controller, as well as a pan manual control signal and a tilt control signal from the manual controller. The bypass switch is configured to allow the DMX signals to bypass the microcontroller directly to the moving head spotlight or flow through the microcontroller.

A light head with auxiliary heat dissipation includes a housing having a light outlet and a light-outgoing lens assembly being arranged at the light outlet. A cover plate is provided at the outer side of the housing. A heat-dissipating air passage is formed between the housing and the cover plate along the length direction of the housing, and both ends of the heat-dissipating air passage are respectively provided with a first air vent and a second air vent. A first air blower is further included for blowing the air in the heat-dissipating air passage to flow between the first air vent and the second air vent.

A luminaire includes a light source and a framing shutter system. The light source is configured to emit a light beam. The framing shutter system includes an aperture that is configured to receive the light beam. The framing shutter system further includes a plurality of shutter blades configured to be positioned across the aperture and mask a portion of the light beam. Each of the shutter blades includes a blade substrate material having a front surface that is configured to receive the light beam and a rear surface on an opposite side of the blade substrate material from the front surface. The front surface of each shutter blade includes a first coating that is configured to reflect one or both of light and heat. The rear surface of each shutter blade may include a second coating configured to reduce reflection of light from the rear surface.

An illumination device includes two illumination sections. The first illumination section includes a plurality of illumination elements that are each configured to emit light in a light spectrum, wherein the light spectrum is variable. The second illumination section includes one or several illumination elements that are each configured to emit light in a fixed light spectrum, wherein the fixed light spectrum is white.

A light fixture includes a lens, at least one light source emitting light towards an input side of the lens, a first compartment comprising a sidewall extending circumferentially around the lens, and a deformable membrane extending from the lens to a distal end of the sidewall. The lens is movable relative to the at least one light source. The first compartment is configured to house the at least one light source. The lens and the deformable membrane seal the first compartment from moisture, particles, or contaminants from outside the light fixture.

A portable multi-function lighting device is provided that includes a built-in digital controller configured to be connected wirelessly with one or more other lighting fixtures in a master-slave relationship in order to perform a coordinated light show. The portable multi-function lighting system is configured with a plurality of different types of lighting fixtures for performing different types of effects. The portable multi-function lighting device wirelessly transmits control signals to other fixtures that include a lighting effect or a theatrical or special effect, which fixtures are external to, i.e., not part of, the portable multi-function lighting device to coordinate a show in which like types of effects of the separate fixtures and of the portable multi-function lighting device are coordinated with one another.
