A lighting control system includes a control card for an illumination device. The control card receives an input signal from a controller electronic device, identifies a type of the illumination device, and uses the identified type to identify an output signal protocol corresponding to the illumination device. If the input signal uses a protocol that differs from that of the output signal protocol, the control card will convert the input signal to the output signal protocol. The controller device may be programmed to enable a user to display and/or control various parameters of various lighting devices.

A system and method for discovering at least one dimming control protocol installed in a plurality of lighting devices and for controlling a plurality of dimming levels of the plurality of lighting devices are disclosed. The system may include at least one gateway that connects to at least one plurality of luminaires and/or LED's, at least one sensor subsystem and at least one power meter. The system and method may exchange information between a plurality of light devices and a self-organized, self-discovering gateway device. The gateway may use one or more known control protocols as an input and is able to handle multiple light devices that support different control protocols. This ability makes the gateway a universal lighting control gateway.

A method of controlling light beam angles of light beams provided by a light fixture includes obtaining a narrowest and a widest beam angle values of a beam angle of a first light beam provided by a first cluster of LED-optics units and obtaining a narrowest and a widest beam angle values of a beam angle of a second light beam provided by a second cluster of LED-optics units. The method also includes controlling the first and second clusters of LED-optics units such that the beam angles of the first light beam and the second light beam are bound by a smaller one of the narrowest beam angle values of the beam angles of the first light beam and the second light beam and by a smaller one of the widest beam angle values of the beam angles of the first light beam and the second light beam.

According to the disclosed embodiments, a three-dimensional (3D) reference environment having one or more environmental lighting reference (ELR) sources is determined by a controller. Also, characteristics of the one or more ELR sources are tracked by the controller. Then, a lighting environment generated by the one or more ELR sources in the 3D reference environment is replicated by the controller by dynamically and automatically controlling one or more physical light sources that illuminate a physical subject according to the characteristics of the one or more ELR sources.

An energy-efficient, compact and cost-effective solution for driving a number of high-power LED groups for lighting applications includes using a single switching power supply together with LEDs connected in series and/or in parallel and pulse width-controlled switches in parallel across the individually controllable LED groups. If the switch of an LED group is ON, the LED group will not light up. If the switch is in the OFF position, the full current of the power supply will pass through the corresponding LED group.

In some examples, automatic light fixture address technology includes methods and apparatuses. In other examples, the method includes receiving a disable forward control command to disable data forwarding through the light fixture; receiving an enable forward control command to enable data forwarding through the light fixture; transmitting address data for the light fixture based on the enable forward control command; and forwarding one or more additional enable forward control commands based on the enable forward control command.

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.

The invention relates to a lighting system comprising at least one light module (3), preferably a plurality of light modules (3), which can be installed in e.g. pool walls of swimming baths or footpaths and have at least one LED (4), wherein the light modules are each connected by means of at least one system cable (2) to a common central and bus-capable controller (1) and can be controlled thereby, wherein the system cable (2) is provided for power supply to the light modules (3) and for control of the respective light modules (3) from the controller (1), and wherein in each case a light module (3) which can be positioned by means of an associated system cable (2) remote from the controller (1) has a housing, which is in particular watertight, in which driver means are disposed for supplying power to the LED (4).

The present invention relates to a dual function light controller for a lighting system comprising a number of light emitting devices. The dual function light controller acts in a stand-alone mode of operation as an independent light controller controlling the lighting system and acts in a peripheral mode of operation act as a peripheral device which at least partially is controlled by a main controller controlling the lighting system. The dual function light controller comprises user switching means enabling a user to switch between the stand-alone mode of operation and the peripheral mode of operation. The present invention relates also to a lighting system comprising such dual function light control device.

A remote follow spot system includes a remote controller that has separately movable parts that are movable in two orthogonal directions, and a display attached to one of said two separately movable parts. The display receives a video feed from a controlled light, that is controlled to move in the same directions as remote controller. 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.
