Patent number: 11239691Abstract: An emergency LED lighting system maintains power to an LED lighting source based on measured voltages and currents provided to the LED lighting source; rolls back or decreases power provided to an LED lighting source over time in order to increase the amount of time the battery can power the LED lighting source; executes a soft start procedure, such that the power provided to the LED lighting source is gradually ramped up during activation of the LED lighting sources; identifies a type of battery coupled to the emergency LED lighting system; cycles the emergency LED lighting system between charging mode and standby mode to reduce power consumption over a window of time; detects AC power or an absence of AC power; and/or uses a status LED to communicate information about the emergency LED lighting system with a remote device.Type: GrantFiled: February 25, 2020Date of Patent: February 1, 2022Assignee: ABL IP Holding LLCInventors: James Clarence Johnson, Dean W. Mavis, Antonio Marques, Gunjan P Patel, Ray Altenburger

Patent number: 9030115Abstract: An LED driver may use a DIAC oscillator circuit to controls a semiconductor switch in a switching circuit. The DIAC oscillator circuit uses rectified line power and so it does not require a separate power source. An LED driver may uses a zero crossing circuit to provide low level dimming. The zero crossing circuit includes a linear circuit or a constant current circuit that keeps a TRIAC dimmer on and stable during low current levels.Type: GrantFiled: March 14, 2013Date of Patent: May 12, 2015Assignee: ABL IP Holding LLCInventor: James Clarence Johnson

Patent number: 8723427Abstract: Board level conditions associated with the operation of multiple LEDs are sensed and used to control a driver that powers the LEDs. The driver is controlled via a 0-10V control interface. The board-level conditions include, but are not limited to, temperature, ambient light, light intensity, operating time, time of day, current, and voltage. An on-board intelligent (OBI) controller processes the 0-10V control signal before it is provided to the driver to better control the LEDs. In some systems the OBI controller works in conjunction with a separate 0-10V controller that controls one or more luminaires.Type: GrantFiled: April 5, 2012Date of Patent: May 13, 2014Assignee: ABL IP Holding LLCInventors: Patrick Collins, Antonio Marques, James Clarence Johnson
