Abstract
Abstract A radio-controlled TV or movie studio spotlight or general purpose illumination instrument; two joy sticks, one for the pan or tilt, the other one for the dim or iris adjustments and settings, respectively, are installed on a panel of a 4-channel radio transmitter accessible for manual actuation to provide the respective commands for a four-channel radio receiver and thereby for the remote control of the lighting equipment functions.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
167 words
A remotely controlled illumination equipment having a rotatable and tiltable spotlight with variable opening and variable light output, structural members and electrical wiring, comprising: a radio-frequency receiver mounted on a said structural member of said illumination equipment, having a plurality of operating channels adapted to receive signals providing power source outputs, a plurality of servomotors each capable of operating a specific illumination equipment element, each said servomotor mounted in the proximity of the to be operated illumination equipment unit, a radio-frequency transmitter, positioned remotely from said radio-frequency receiver, having a plurality of operating channels compatible with those of said radio-frequency receiver, a plurality of multi-throw joy sticks connected with said radio-frequency transmitter, each said joy stick throw, when manually actuated, causing a specific command signal for transmission through a specific channel to the corresponding channel of said radio-frequency receiver, the availability of a specific power source output energizing a said servomotor for the duration of a said command signal transmission and thereby the execution of said command.
Claim 2
Dependent Claim
167 words
A remotely controlled illumination equipment having a rotatable and tiltable spotlight with variable opening and variable light output, structural members and electrical wiring, comprising: a radio-frequency receiver mounted on a said structural member of said illumination equipment, having a plurality of operating channels adapted to receive signals providing power source outputs, a plurality of servomotors each capable of operating a specific illumination equipment element, each said servomotor mounted in the proximity of the to be operated illumination equipment unit, a radio-frequency transmitter, positioned remotely from said radio-frequency receiver, having a plurality of operating channels compatible with those of said radio-frequency receiver, a plurality of multi-throw joy sticks connected with said radio-frequency transmitter, each said joy stick throw, when manually actuated, causing a specific command signal for transmission through a specific channel to the corresponding channel of said radio-frequency receiver, the availability of a specific power source output energizing a said servomotor for the duration of a said command signal transmission and thereby the execution of said command.
Claim 3
Dependent Claim
24 words
A remotely controlled illumination equipment as defined in claim 1, wherein a first servomotor operates the panning movement of the spotlight of said equipment.
Claim 4
Dependent Claim
24 words
A remotely controlled illumination equipment as defined in claim 1, wherein a second servomotor operates the tilting movement of the spotlight of said equipment.
Claim 5
Dependent Claim
18 words
A remotely controlled illumination equipment as defined in claim 1, wherein a third servomotor operates a spotlight-dimming potentiometer.
Claim 6
Dependent Claim
25 words
A remotely controlled illumination equipment as defined in claim 1, wherein a fourth servomotor adjusts the iris opening of the spotlight of the illumination equipment.
Claim 7
Dependent Claim
47 words
A remotely controlled illumination equipment as defined in claim 1, wherein the output speed of each servomotor shaft is reduced from the rotor speed by means of a single-thread worm and spur gear transmission imparting a self-locking feature on the movable members when the servo is de-energized.
Claim 8
Dependent Claim
55 words
A remotely controlled illumination equipment as defined in claim 1, wherein each mechanical coupling between a movable instrument member and a servomotor shaft is equipped with a friction clutch calibrated so as to allow for manual over-riding of a sald element for adjustment correction and for manual movement in case of a power outage, respectively.
