Patent number: 11384931Abstract: A combined lighting and speaker device having a central longitudinal axis defining a forward and a rearward direction and a radially outward and a radially inward direction is provided. The device comprises a tweeter; a tweeter horn positioned radially outwardly of the tweeter; a speaker positioned rearward of the tweeter horn; and a light emitting diode, LED, assembly positioned radially outwardly of the tweeter. The LED assembly comprises one or more light emitting diodes, LEDs, and a lens having a forward surface. The tweeter horn has an inner edge in communication with an outer edge of the tweeter, so that the tweeter horn forms a guide to direct sound produced by the tweeter away from the speaker when in use. At least part of the tweeter horn is provided by the forward surface of the lens.Type: GrantFiled: April 16, 2019Date of Patent: July 12, 2022Assignee: Zuma Array LimitedInventors: Morten Warren, Fong Ming, Laurence Dickie, Philip John Rimmer, John Daniell Hebert, Ed Rose

Patent number: 10433379Abstract: Several aspects of power distribution systems are described. One aspect relates to apparatus for providing a direct current to a load comprising one or more light emitting diodes. The apparatus comprises: a rectifier operatively connectable to a secondary winding of a transformer whose primary winding is for carrying a high-frequency alternating current; a first capacitor operatively connectable to the secondary winding; and a second capacitor operatively connectable, at least partly via the rectifier, to the secondary winding. The first and second capacitors together provide a reactance referred to the primary winding which substantially compensates for the reactance of the primary winding.Type: GrantFiled: May 12, 2018Date of Patent: October 1, 2019Assignee: Greengage Lighting LimitedInventor: Philip John Rimmer

Patent number: 7436675Abstract: A flexible cable is provided for a lighting system having a power supply that includes a power supply input to receive a first signal having a first frequency and a circuit for converting the first signal to a second signal, and at least one luminaire coupled to a lamp driver. The cable comprises a first leg of wires for carrying the second signal. The first wire electrically connects a loop output of the power supply to an input of the lamp driver and a second wire electrically connects an output of the lamp driver to a loop return of the power supply. The cable further comprises a second leg of wires electrically connected to a ground of the power supply and the ground of the lamp driver. The second signal has a substantially constant current and a second frequency distinctly higher than the first frequency. The flexible cable further comprises a modular connector.Type: GrantFiled: March 20, 2006Date of Patent: October 14, 2008Assignee: Juno Manufacturing, Inc.Inventors: Philip John Rimmer, Carole Frances Sherrington
