An optical device including a support mounted on a rotational-drive motor, and a reflective optical component, the support including at least one sleeve coaxial with the rotational-drive axis, of which sleeve one end defines an inlet orifice and which sleeve in its wall includes an opening defining an outlet orifice, and inside which sleeve the reflective optical component is housed in such a way that a beam of light entering via the inlet orifice is reflected by the reflective optical component to exit via the outlet orifice. An optical component mounted and retained in the sleeve as a result of cooperation of shape between it and the wall of said sleeve is also discussed.

Practical lighting is the technique of using light sources that are seen within the frame of a shot. Apparatus 10 and 10A is a lightweight, magnetically mounted, light diffusing housing for LED ribbon which is designed to look like a standard fluorescent tube when used as practical lighting. Control wires can be easily and repeatedly removed via screwed terminal housings (10) or connected via industry standard phoenix receptacle (10A) housed discreetly one of its two end caps, providing a solderless connection with either apparatus. The magnets internally installed adhere the apparatus to standard metal fluorescent housings without damage to the installed fixture negating the need of additional mounting rigging hardware.

A waterproof light head structure of a stage light fixture includes a main bracket, a front cover and a rear cover respectively disposed at the front side and the rear side of the main bracket, and a light outgoing lens assembly disposed above the main bracket. The main bracket includes an upper support and a lower support, the upper support is mounted above the lower support and is in sealed and detachable connection with the lower support. The upper support is at least used for mounting an optical lens assembly, and the lower support is at least used for mounting an effect assembly. The main bracket is disposed in a cavity formed by joining the front cover with the rear cover, and the front cover and the rear cover are in sealed connection with the light outgoing lens assembly and the main bracket along the edges thereof.

An illumination device includes a plurality of light sources arranged in at least a first group of light sources having one or more light sources and a second group of light sources having one or more light sources and further includes one or more light collectors, each being arranged for collecting light from one or more light sources from the first group of light sources and for converting the collected light into one or more light beams. The first and second groups of light sources are each individually controllable. The first and second groups of light sources are both arranged for emitting light from a space on one side of the one or more light collectors. The illumination device is arranged so that light emitted from the second group of light sources through the one or more light collectors defines a pattern comprising one or more elongated elements.

A small-sized aperture assembly includes a base plate, an optical shutter fixed to the base plate, a motor providing a driving force, a linkage mechanism with one end connected to the motor, and a transition gear located between the linkage mechanism and the optical shutter. A periphery of the optical shutter is provided with a sawtooth segment meshed with the transition gear, and the other end of the linkage mechanism is hinged to the transition gear, so that the linkage mechanism drives the transition gear to move under the driving of the motor, and enables the optical shutter to switch between a closed state and an open state.

A waterproof base convenient to maintain includes a bottom frame which is integrally die-cast formed, and an upper cover with a pivoting hole covering the bottom frame. The upper cover includes a first cover body and a second cover body which are spliced to each other. The pivoting hole is formed by jointly splicing the first cover body and the second cover body, and an oil seal for sealing the outer side of a pivoting shaft penetrated the pivoting hole is disposed at the pivoting hole. The oil seal is mounted and fixed by a mounting plate. A first sealing strip seals the first cover body, the second cover body and the mounting plate with respect to each other, the first cover body and the second cover body abut against the bottom frame, and second sealing strips are disposed at abutting positions.

A lighting device for professional illumination. The device includes a main housing having a front opening, a first light source, a first reflector configured to receive at least a portion of light emitted by the first light source and to reflect at least a portion thereof, and a second reflector configured to receive at least a portion of light reflected by the first reflector and to reflect at least a portion thereof. The lighting device is configured to emit at least a portion of light reflected by the second reflector out of the lighting device through the front opening. The lighting device further includes an actuator configured to move the first reflector or the second reflector in relation to each other in response to a predetermined control signal.

A LED module (24) for a blinder (10) having several LEDs (30) of the color warm white, one LED or several LEDs (30) of the color red, and one LED or several LEDs (30) of the color amber.

A method and an apparatus and system for producing light using LED lighting with output within a predetermined desired color temperature range for commercial lighting uses. A preferred embodiment includes a first and second group of LEDs arranged in an alternating matrix configuration, each group of LEDs configured to produce light in a predetermined color temperature range. In a preferred embodiment, an LED light system includes a tubular LED lamp having substantially the same size and dimensions as a traditional fluorescent lamp tube and a control box for controlling power input and power gain to the first, second, or both groups of LEDs.
