A light puck that attaches to a wire rope tension grid has a top cover with a plurality of slots to receive wire ropes therein and a corresponding bottom cover. There is also a light fixture having a plurality of LEDs disposed between the top cover and the bottom cover, the light fixture aligned with an opening in the bottom cover. A biasing plate is positioned between the light fixture and the top cover and has adjustment screw associated therewith to bias the biasing plate relative to the top cover.

A spotlight system for illuminating a film or stage environment comprises a spotlight for generating light; and at least one optical component couplable to the spotlight for producing at least one spatial light distribution, wherein the optical component and/or the spotlight has/have a memory in which information on the spatial light distribution producible by the optical component is stored.

A stage light with electronically adjustable lighting effects comprises a light box with a heat dissipation mechanism, a heat dissipation hole formed on a rear side communicating with the mechanism, and a light panel disposed on a front side; a dimmable glass disposed on the light panel, comprising an outer glass layer and liquid crystal molecules; and a control box disposed on the light box and having a control circuit electrically connected to the glass, the control circuit comprises a central processing unit, a voltage regulating unit and a signal receiving unit, the signal receiving unit receives a digital multiplexing signal and transmits it to the central processing unit that generates a voltage adjustment command through the signal and transmits the command to the voltage regulating unit, the voltage regulating unit controls arrangement of the liquid crystal molecules through the command to change a light transmittance of the glass.

The present disclosure provides a photography lamp. The photography lamp includes a front housing, an ejector rod, a bracket, and a limiting structure. An accessory slot with a through-hole is arranged on a side of the front housing, the ejector rod is movably arranged into the through-hole, the bracket is arranged on another side of the front housing away from the accessory slot The photography lamp provided by the present disclosure can be operated conveniently. When the accessory is installed on the video lamp, the bracket is not susceptible to interference from the accessory of the photography lamp.

An innovative light fixture for use with acoustical shells is disclosed. The fixture incorporates a dome gimbal to allow rotation front-to-back and left-right around a horizontal axis and a third axis of rotation around a vertical axis. The dome configuration allows for a low profile and toolless adjustment allows stage side aiming by hand.

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.

A simple light-blocking and air-exhausting device includes a ventilation plate and a light-blocking plate arranged oppositely and spaced apart from each other. The ventilation plate is provided with an air vent formed by die-cutting the ventilation plate, and vertical projection of the light-blocking plate on the ventilation plate overlaps the air vent. The vertical projection of the light-blocking plate on the ventilation plate overlaps the air vents on the ventilation plate, so that the light-blocking plate can prevent light from leaking out of the air vents, while air flow can flow out from a gap between the light-blocking plate and the ventilation plate.

The disclosure relates to a light board and a spotlight. The light board comprises a circuit board having multiple mounting positions, and lamp beads mounted in the mounting positions, which comprise multiple cool color lamp beads and multiple warm color lamp beads, the cool and warm color lamp beads are configured to form multiple lamp bead rows, which are arranged along a first direction. Each lamp bead row comprises both the cool and warm color lamp beads, a difference between the number of the cool and warm color lamp beads does not exceed 2, a difference between the number of the cool and warm color lamp beads in two adjacent lamp bead rows does not exceed 3, and a total number of cool color lamp beads is equal to that of warm color lamp beads. The technical solution of the disclosure is beneficial to improve lighting effects of lights.

A luminaire includes a luminaire mechanism, a stepper motor, an absolute multi-turn rotational position sensing system, and a control system. The stepper motor moves the luminaire mechanism. The absolute multi-turn rotational position sensing system includes absolute rotational sensors that detect absolute positions of a cam indexer on the motor shaft and an indexer wheel coupled to the cam indexer. The indexer wheel rotates by a predetermined amount in response to one full rotation of the cam indexer. The control system determines an absolute position of the luminaire mechanism based on information from the absolute rotational sensors relating to the positions of the cam indexer and the indexer wheel. The control system receives a commanded position for the luminaire mechanism and causes the stepper motor to move the luminaire mechanism to the commanded position based on the absolute position of the luminaire mechanism.
