Barrier operator with safety lighting

Abstract

An uninterruptible power source (UPS) for supplying power to a barrier operator when mains power has failed is disclosed. The UPS includes a UPS controller for detecting and responding to a mains power failure and capable of generating a plurality of control signals. A backup power source and an up-converter is connected to the UPS controller, wherein the up-converter increases the voltage of the backup power source when needed. A switch is responsive to one of the plurality of control signals of the UPS controller and toggles the operator barrier between the up-converter and the mains power source, and awakens the operator via a standby receiver power line. Another embodiment awakens the operator anytime a UPS receiver receives a preamble of a wireless transmission signal. Auxiliary lighting may also be associated with the UPS and/or photo-electric safety devices.

1 . A barrier operator system with safety lighting, comprising:
 an operator controller and associated linkage which moves a barrier between limit positions;   a photo-electric sensor operatively connected to said operator controller, said photo-electric sensor having a sending unit which projects a light beam to a receiving unit, wherein interruption of said light beam during door movement is communicated to said operator controller;   a light associated with at least one of said sending unit and said receiving unit.   
   
   
       2 . The system according to  claim 1 , wherein operation of said light is controlled by said operator controller and operates on a voltage less than that supplied to said operator controller. 
   
   
       3 . The system according to  claim 1 , wherein said photo-electric sensor communicates with said operator controller with wireless signals. 
   
   
       4 . The system according to  claim 3 , wherein said photo-electric sensor is battery powered. 
   
   
       5 . The system according to  claim 1 , wherein said light is directed downwardly to primarily illuminate a floor. 
   
   
       6 . The system according to  claim 1  wherein said light is movable in any direction with respect to said unit. 
   
   
       7 . The system according to  claim 1  further comprising:
 an ambient light sensor associated with one of said sending and receiving units and sending an ambient light signal to said operator controller which illuminates said light according to other conditions of the system.   
   
   
       8 . The system according to  claim 1 , further comprising:
 an uninterruptible power source which supplies back-up power to said operator controller and associated linkage when mains power is removed from said operator controller, wherein said back-up power is supplied to said light.   
   
   
       9 . The system according to  claim 8 , further comprising:
 an ambient light sensor associated with one of said sending and receiving units and sending an ambient light signal to said operator controller which illuminates said light according to other conditions of the system.   
   
   
       10 . The system according to  claim 1 , wherein said light is battery powered. 
   
   
       11 . The system according to  claim 1  further comprising:
 an ambient light sensor associated with said photo-electric sensor which generates an ambient light signal received by said light for operation thereof.
