The invention provides a light system with a signal shaping module. In view of the problems of signal errors of DMX signals caused by a large number of lights and a long signal transmission distance between lights, an optocoupled isolation module and a signal processing module are arranged to reshape a received DMX signal to effectively filter an interference signal out of the DMX signal and correct the width of the DMX signal to avoid errors caused by the change in data rate to realize error-correction shaping of the transmitted signal, such that the transmission distance of the DMX signal is effectively prolonged, thus improving signal transmission accuracy and stability.

A method for controlling an object space having an associated object environment includes the steps of, defining a target set of coordinates in the object space, recognizing the presence of a predetermined object in the object space, and determining a coordinate location of the recognized predetermined object in the object space. The method further includes determining the spatial relationship between the recognized predetermined object and the target set of coordinates, comparing the spatial relationship with predetermined spatial relationship criteria, and if the determined spatial relationship criteria falls within the predetermined spatial relationship criteria, modifying the object space environment.

A lighting controller includes a microcontroller, a first dimming circuit utilizing a DALI protocol, a second dimming circuit utilizing a non-DALI dimming technology, a DALI bus over which DC power is supplied to the first dimming circuit and that is used by the first dimming circuit to communicate an output dimming signal to the lighting fixture, and a multiplexing circuit (MUX) operable to couple an output of either the first dimming circuit or the second dimming circuit to the controller's dimming output.

The first dimming circuit includes a second set of diodes to isolate the second dimming circuit from the DALI bus when the first dimming circuit is deactivated and the second dimming circuit is activated.

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.
