Low-power illumination system and associated barrier operator
First Claim
1. A low-power illumination system usable in the event of a mains power source failure comprising:
- an illumination unit comprising;
a unit controller;
a unit backup power supply coupled to said controller to provide backup power thereto;
a low-power light element coupled to said controller, wherein said unit controller energizes said light element so as to generate light via said backup power supply when the mains power source fails, and said controller de-energizes said light element when the mains power source is operational; and
a unit receiver coupled to said controller; and
a remote transmitter configured to communicate with said unit receiver, wherein in response to a command sent by said remote transmitter, said controller toggles said light element between on and off states.

Abstract
A low-power illumination system for use with an associated barrier operator, or independently, comprises at least one illumination unit adapted to be operable via mains power and a backup power supply, such as a battery. Accordingly, if mains power fails, a low-power light element maintained by the illumination unit may be responsively powered by the backup power supply to provide backup lighting. Alternatively, the barrier operator may be configured to detect a mains power failure, such that when such failure is detected, an illumination command signal also needs sent to the at least one associated illumination unit causing for it to be illuminated.

12. A barrier operator and low-power illumination system comprising:
-
a barrier operator comprising; an operator controller adapted to be coupled to a mains power source; an operator transceiver coupled to said operator controller; and an operator backup power supply coupled to said operator controller to provide backup power thereto; a low-power illumination unit comprising; a unit controller adapted to receive mains power; a unit backup power supply coupled to said controller to provide backup power thereto; a unit receiver coupled to said unit controller; and a low-power light element coupled to said unit controller; wherein when said operator controller detects a failure of said mains power source, said operator controller remains operational via said unit operator backup power supply and said operator transceiver sends an illumination command to said unit receiver, wherein said unit controller responsively energizes said low-power light element via said unit backup power supply. - View Dependent Claims (13, 14, 15, 16)
