Patent number: 10104745Abstract: A power handling system of a digitally addressable lighting interface (DALI) system controls switches connected with a bus of the DALI system that powers lower power light sources. A power supply circuit receives energy conducted on the bus to the lower power light sources and conducts at least part of the energy to a capacitor. Electric energy is stored in the capacitor until the capacitor stores at least a designated threshold of input voltage of a controller. The capacitor powers the controller to close one or more switches using at least some of the stored electric energy.Type: GrantFiled: March 18, 2016Date of Patent: October 16, 2018Assignee: General Electric CompanyInventors: Lajos Csibi, Jeno Balazs, Richard Boros, Tamas Daranyi, Gabor Pap

Patent number: 9807846Abstract: Single channel digital addressable lighting interface (DALI) systems can include a dedicated external power supply that operates in a constant voltage/constant current mode to meet requirements of the DALI bus. A lighting controller is powered from the DALI bus. In one embodiment of the inventive subject matter, a lighting system is provided that includes two or more control (e.g., DALI) buses and a multichannel power supply that can be used for powering a controller of the system with constant voltage and to power separate control buses with separate and constant current. In order to protect the controller and buses from overloads caused by miswiring or other erroneous conditions, a protection circuit assembly is provided.Type: GrantFiled: December 4, 2015Date of Patent: October 31, 2017Assignee: GENERAL ELECTRIC COMPANYInventors: Tamás Darányi, Lajos Csibi, Gábor Pap

Patent number: 9119273Abstract: A compact fluorescent lamp (CFL) ballast driver includes first, second and neutral AC voltage terminals, a full wave rectifier between the first AC voltage terminal and the neutral AC input terminal, and a separate branch between the second AC voltage terminal and the neutral AC input terminal. A resonator circuit includes at least two inductors and provides its output voltage to a CFL lamp. The driver includes a first state detector circuit to monitor the first AC voltage terminal, and a second state detector circuit to monitor the second AC voltage terminal. The first and second state detector circuits activate respective first and second switches. The first switch shunts one inductor of the resonator circuit, and the second switch shunts another inductor of the resonator circuit. The driver can be housed in a CFL having a capper, a three-way lamp base adjacent to the capper and an arc tube.Type: GrantFiled: November 25, 2013Date of Patent: August 25, 2015Assignee: GENERAL ELECTRIC COMPANYInventors: Jácint Gergely, Gábor Szabó, Loránd Lehel Tóth, Lajos Csibi, Tamás Vásárhelyi
