Patent number: 8866405Abstract: A lighting device has a direct-current power generation circuit, a rectangular-wave generation circuit, a pulse generating circuit, lamp-voltage detection means, and pulse-generation command means. The direct-current power generation circuit generates direct-current power from external power. The rectangular-wave generation circuit converts the direct-current power to rectangular-wave alternating-current power. The pulse generating circuit superposes high-voltage pulses on the rectangular-wave power output from the rectangular-wave generation circuit and starts a discharge lamp. The lamp-voltage detection means detects, in digital form, a lamp voltage supplied to the discharge lamp. The pulse-generation command means issues a pulse generation command to the pulse generating circuit when the value detected by the lamp-voltage detection means reaches a predetermined no-load-voltage determination level.Type: GrantFiled: August 24, 2012Date of Patent: October 21, 2014Assignee: Eye Lighting Systems CorporationInventors: Yoshihisa Umezawa, Kensuke Kaneko, Tomokazu Osato

Patent number: 8836227Abstract: A lighting device has a power-factor correction circuit 6, a step-down chopper circuit 8, a full-bridge circuit 10, control ICs for these circuits and a driving-voltage supply circuit 14. The supply circuit 14 supplies a driving voltage to the control ICs. The control IC outputs the on/off driving voltage to a switching element of the corresponding circuit 6 to 10. The lighting device also has a detector 16 and judgment equipment 18. The detector 16 detects the driving voltage supplied from the supply circuit 14. The judgment equipment 18 instructs the control ICs to start outputting the on/off driving voltages in the order from the control IC close to the power source 2 to the control IC close to the discharge lamp 4 when the driving voltage detected by the detector 16 reaches a predetermined value during the time when the driving voltage supplied from the supply circuit 14 rises.Type: GrantFiled: August 23, 2012Date of Patent: September 16, 2014Assignee: Eye Lighting Systems CorporationInventors: Yoshihisa Umezawa, Kensuke Kaneko

Patent number: 8593264Abstract: A remote lighting control system is for remote lighting control of a plurality of discharge lamps. This system has the installed electronic ballasts of each discharge lamp. Each electronic ballast has a transceiver and a controller, the transceiver exchanges control information with the controller. The control command contains the identifiable information to specify one of a plurality of electronic ballasts. When the transmitter is received the control command, the transceiver transfers the received control command to other electronic ballasts further. Moreover, if the control command is the one that the identifiable information specifies own ballasts, the control information based on the received control command is send to own controller, and the controller control the discharge lamp. According to this system, when a lot of lamps was arranged the factory etc. comparatively widely, the user's remote control is not limited to the narrow scope.Type: GrantFiled: March 3, 2010Date of Patent: November 26, 2013Assignees: Eye Lighting Systems Corporation, Nippon Antenna Co., Ltd.Inventors: Yoshihisa Umezawa, Ichirou Terayama, Masakazu Ikeda, Yusuke Tainaka
