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.

The disclosure relates to modular LED imaging projector and optical systems and apparatuses. A light-emitting diode (LED) engine module emits a light beam that is homogenized and focused through a predetermined focal point. The LED engine module is detachably attached to a posterior connection point of a base body assembly. A collimating lens within the base body assembly refocuses the light beam to reduce divergence.

The present invention belongs to the technical field of light tracking devices, and is specifically an automatic focus following, dimming and light tracking device comprising a Z-axis rotating focus following mechanism, an X-axis rotating focus following mechanism, and a Y-axis translational focusing mechanism. The Z-axis rotating focus following mechanism comprises a pedestal and a surface shell rotating about a Z-axis. A tracking and positioning module is provided in front of the surface shell. A lamp holder body rotating about an X-axis is provided on the top surface of the surface shell. A lens, a distance measuring unit and an illuminance measuring unit are provided on the front end of the lamp holder body. The lamp holder body is provided internally with a lamp holder assembly to reciprocate linearly along a Y-axis. The lamp holder assembly is provided relative to the lens. During use, manual intervention is not required.

A debubbler system includes a hollow enclosure and a vent assembly. The hollow enclosure includes comprising an inlet configured to receive coolant into the hollow enclosure and an outlet configured to direct coolant out of the hollow enclosure. The vent assembly includes a vent member configured to rotate about two or more axes within the hollow enclosure. Additionally, the vent member includes an open end configured to remain above a coolant level within the hollow enclosure as the vent member rotates about the two or more axes and a tube configured to flow air, coolant, or both, from the open end of the vent member out of the hollow enclosure.

A light source for a spotlight (100) for illuminating a film, studio, stage event and/or theatre environment comprises a carrier (10), which is designed at least in part as a single-layer circuit board, a plurality of LEDs (12) with N>2 different colour types and a current line system (14) with a plurality of lines (141, 142) with N line types for supplying the LEDs (12) being arranged on the carrier (10).

The present invention relates to a lighting device for creating a light beam comprising a light source and an optical element positioned along an optical axis (80) between said light source and an outlet for said light beam wherein said optical element comprises an at least partially transparent or translucent effects wheel (1), said effects wheel (1) being movable between a first active position in which the effects wheel (1) is positioned along said optical axis (80) and a second inactive position, in which the effects wheel (1) is positioned outside said optical axis (80), and actuation means suitable for moving the effects wheel (1) in a back-and-forth movement between its first active position and its second inactive position.

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.

The present disclosure provides a photography lamp. The photography lamp includes a housing, an ejector rod, and a bracket. The housing includes a front housing and a mid-frame, an accessory slot is arranged on a side of the front housing, the bracket is arranged on another side of the front housing away from the accessory slot and slidably connected to the front housing; the bracket includes a connecting rod and a pushing rod connected at an included angle. The space occupied by the bracket is reduced, and the structure of the photography lamp is more compact and smaller.

A flat-type effect module includes a first flat motor and an effect wheel assembly. The first flat motor has a first stator to generate a magnetic field when energized, and a first rotor arranged outside the first stator in a sleeving mode. The effect wheel assembly is fixed to the first rotor, and the effect wheel assembly includes a wheel body for generating a light effect which is provided with effect areas for intercepting a light beam to change the color and/or shape thereof. According to the present invention, no rotating shaft, such as the traditional rotating shaft motor has, exists on the first flat motor, the effect wheel assembly in the present invention is directly fixed to the first rotor, so that the height of the rotating shaft can be reduced and more effect elements can be arranged.

A light-recycling light system (LRLS) that, in some embodiments, uses a transparent solid body (also called a lens) with some surfaces having total-internal-reflection (TIR) characteristics, optionally having no reflective coatings, making the system easy to make and low cost. In some embodiments, the lens includes an input face, an output face, and a curved (elliptical or parabolic) side surface that exhibits TIR, wherein the curved side surface defines a first focus at the input face and a second focus at the output face, so recirculating light entering at the first focus and reflecting at one side of the curved surface by TIR toward the second focus, hen reflects at the second focus toward the opposite side of the curved surface, and then reflects at the second side of the curved side surface by TIR toward the first focus. A light source emits light at the first focus.
