Remote lighting control system

Claim 2

A remote lighting control system for adjusting a plurality of electrical spotlights in turn comprising: a plurality of controllable means coupled to respective spotlights to control spot size, shape and location; a source of pressurized fluid; a plurality of selector means individually coupled to respective spotlight controllable means for directing said flUid to selected controllable means; and valve means for passing said fluid to each selector means only when said spotlight is energized.

Claim 3

A system in accordance with claim 1 wherein said controllable means include a cylinder having a piston therein, and means for applying force from the piston to adjust said spotlight.

Claim 4

A system in accordance with claim 1 wherein the selector means includes a selector having a plurality of positions for applying pressurized fluid to various ones of the controllable means individually and in turn.

Claim 5

The system of claim 1 wherein the selector means includes pairs of connecting tubes for directing reversible actuation of the controllable means.

Claim 6

A system in accordance with claim 1 wherein said selector means includes means to direct fluid to said spotlight for cooling a lamp in said spotlight during prolonged operation of said spotlight.

Claim 7

A system in accordance with claim 1 wherein a plurality of spotlights are controlled each by a separate selector means, said selector means being driven in unison, each of said spotlights being sequentially adjusted with said fluid being coupled only to the selector means associated with the spotlight being adjusted.

Claim 8

The system of claim 6 wherein the selector means includes a selector having a plurality of positions for applying pressurized fluid to various ones of the controllable means individually and in turn, and wherein is further included remote control means for driving the selector means in unison between selected ones of said positions.

Claim 9

The system of claim 7 further including a remote switch located in a remote unit containing said remote control means for selectively energizing a particular one of said spotlights and its associated valve means.

Claim 10

The system of claim 1 wherein each spotlight lamp and its associated valve means are connected electrically in parallel for coincident actuation by a remote switch.

Claim 11

A remote lighting control system for adjustably controlling a plurality of spotlights in turn from a remote location comprising: a plurality of controllable actuators arranged by groups, each group being coupled to a corresponding spotlight and including means for adjusting spot size, shape and location; a plurality of selectors, one for each group of actuators, coupled to select among its corresponding group; a source of pressurized fluid; a plurality of electrically actuated valves connected to control the application of pressurized fluid from the source to the selectors, each valve being connected electrically in parallel circuit with its corresponding spotlight lamp and fluidically in series with the selector for said spotlight; and a remote control unit having means for controlling the position of all of said selectors together and for energizing the parallel valve and lamp circuit of one or more spotlights, thereby to control the adjustment of the energized spotlights.

Claim 12

A remote lighting control system for adjustably controlling a plurality of spotlights in turn from a remote location comprising: a plurality of controllable actuators arranged by groups, each group being coupled to a corresponding spotlight and including means for adjusting spot size, shape and location; a plurality of selectors, one for each group of actuators, coupled to select among its corresponding group; a source of pressurized fluid; a plurality of electrically actuated valves connected to control the application of pressurized fluid from the source to the selectors, each valve being connected electrically in parallel circuit with its corresponding spotlight lamp and fluidically in series with the selector for said spotlight; and a remote control unit having means for controlling the position of all of said selectors together and for energizing the parallel valve and lamp circuit of one or more spotlights, thereby to control the adjustment of the energized spotlights.

Claim 13

The system of claim 10 further including means for cooling the spotlight lamps; means for connecting said cooling means with a home position in the corresponding selector; and means in the remote control unit for driving the selectors to the home position so that pressurized fluid is directed to the cooling means of the spotlights which are energized.

Claim 14

A remote lighting control system comprising: a plurality of spotlights each having a plurality of framing shutters with each shutter moveable by a handle; moveable means for positioning each spotlight about first and second axes; a plurality of actuator means respectively associated with said shutters and said positioning means; a source of pressurized fluid; selector means driven in unison for each of said spotlights; and remote control means for energizing a given spotlight and controlling the application of pressurized fluid to only one actuator means associated with only the given spotlight at a time.

Claim 15

A remote lighting control system comprising: a plurality of spotlights each having a plurality of framing shutters with each shutter moveable by a handle; moveable means for positioning each spotlight about first and second axes; a plurality of actuator means respectively associated with said shutters and said positioning means; a source of pressurized fluid; selector means driven in unison for each of said spotlights; and remote control means for energizing a given spotlight and controlling the application of pressurized fluid to only one actuator means associated with only the given spotlight at a time.
