#$%^&*AU2017101659A420180118.pdf#####Australia Patents Act 1990 Redundancy Controller Invention Innovation patent Application Date: 28th November 2017 Revision 1 ABSTRACT The redundancy controller is a device that is placed between a primary and a secondary control gear and selects the secondary control gear upon failure of the primary control gear. Failure of the primary control gear is deemed to be an output failure, where it is unable to supply the LED source with the necessary signals, voltage and current, to operate it successfully. The method of switching between control gear and ensuring that each control gear element is completely isolated when not in use can be achieved using mechanical relays, requiring 4 Pole, Double Throw, contacts or possibly with two series connected 2 Pole, Double Throw, relays or even with four series connected 1 Pole, Double Throw contact relays. The use of other electronic switching devices may also be utilised with a trade off on cost and reliability, such as solid state relays. Mechanical relays have long-life switching cycles in the order of over 100,000 operations and are not prone to damage due to electrical surge. The implementation of a redundancy device must be such that the MTBF is far greater than that of the control gear it is switching.Australia Innovation Patent Redundancy Controller Invention Innovation Patent application Date: 28th November 2017 Revision 1 DRAWINGS The redundancy controller is a device that is placed between a primary and a secondary control gear and selects the secondary control gear upon failure of the primary control gear.
