A method of pixel control which reduces the number of DMX control channels required for generation of artistic pixel patterns displayed on a large number of pixel LEDs is described. Further described are a set of control parameters which facilitate the introduction of pixel control and sophisticated pixel pattern generation without a costly DMX controller upgrade. Also described is a device for generating lighting effects. The device may be portable, battery-powered, radio-controlled and small enough to easily hide in most theatrical and film sets, set pieces, props, and practicals. The device may be configured to process DMX data for controlling and generating graphical patterns among pixel LEDs based on the set of one or more control parameters. The method and device relocate the processing of the DMX data from the DMX controller to one or more individual hardware drivers for the pixel LEDS.

A lamp control system includes at least one first lamp network, at least one second lamp network and a lamp control gateway. The first lamp network is configured to emit light and to transmit a first message, and includes a first physical layer. The second lamp network is configured to emit light and to transmit a first message, and includes a second physical layer different from the first physical layer. The lamp control gateway includes a processing module that is configured to receive the first message and the second message and to convert the first message and the second message in such a way that a first converted message and a second converted message comply with a predefined protocol.

The present invention relates to a system, method, and apparatus for powering intelligent lighting networks. The power for the intelligent lighting network is supplied by Power-over-Ethernet (PoE) switches and/or Mid-Spans, which are conditioned by a powered device to distribute power tuned specifically for each, at least one light emitting diode (LED) fixture. The Power-over-Ethernet switch and/or Mid-Span with associated router and wireless access point can be used to communicate with, and power a sensor network that collects data relevant to the intelligent lighting network. Optionally, the Power-over-Ethernet switch and/or Mid-Span can be used to communicate with, and power a network of sensors that collects data relevant to the space the intelligent lighting network is operating in, or can be used to communicate with and power a network of AC wall plugs that can be turned on and off, and various switches, relays, and PLCs, RFID systems, USB hubs, etc.

A remote follow spot system includes a remote controller that has a body movable in pan and tilt directions, and an attached display. Movements of the body in the pan and tilt directions are translated into signals sent to a light to cause the light to move in the same directions as the body. The display receives a video feed from a camera mounted on the controlled light. The display hence shows the field of view where the light is pointing. In this way, an operator of the follow spot can control the light without physically being near the light.

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.

Systems and methods for controlling a light emitting diode (LED) system having a plurality of LED arrays are provided. The lighting system can include a dimmable LED driver circuit configured to provide a driver output suitable for providing a driver current to the LED arrays. A current splitter circuit can be provided between the LED driver circuit and the plurality of LED arrays to control the ratio of current from the driver output provided to each of the plurality of LED arrays. The current splitter circuit can be configured to control the current ratio provided to the plurality of LED arrays independently of the driver output according to a current ratio control curve based at least in part on a variable reference signal provided at the current splitter circuit.

A controller comprising: a first holding location for storing or buffering two or more lighting control frames of a lighting control protocol, for transmission one-after-another in a temporal sequence over a lighting network in order to control at least one lighting device of the lighting network; and a second holding location for storing or buffering at least one status query of a device management protocol, for transmission over the lighting network in order to query a status of at least one lighting device of the lighting network. The controller further comprises an arbitrator configured to automatically detect when one of the lighting control frames is redundant with respect to another of the lighting control frames within a predetermined number of said frames in said sequence, and in response to automatically cause the status query to be transmitted in place of the redundant lighting control frame in said sequence.
