Publication number: 20090273286Abstract: A ballast having a microprocessor embedded therein is controlled via four inputs. The ballast includes a high-voltage phase-controlled signal provided by a dimmer and an infrared (IR) receiver through which the ballast can receive data signals from an IR transmitter. The ballast can also receive commands from other ballasts or a master control on the serial digital communication link, such as a DALI protocol link. The fourth input is an analog signal, which is simply a DC signal that linearly ranges in value from a predetermined lower limit to a predetermined upper limit, corresponding to the 0% to 100% dimming range of the load. The output stage of the ballast includes one or more FETs, which are used to control the current flow to the lamp. Based on these inputs, the microprocessor makes a decision on the intensity levels of the load and directly drives the FETs in the output stage.Type: ApplicationFiled: July 15, 2009Publication date: November 5, 2009Applicant: LUTRON ELECTRONICS CO., INC.Inventors: Dragan Veskovic, Robert A. Anselmo, Mark Taipale, Matthew Skvoretz, Joel S. Spira

Publication number: 20090184840Abstract: A processing circuit for providing electronic photosensor information over a communication link. The processing circuit comprises a photosensor input circuit adapted to be directly coupled to a photosensor for receiving the electronic photosensor information from the photosensor. Further, a communication port is provided that allows for transmitting and receiving messages over the communication link. Moreover, a processor is provided that is coupled to the photosensor input circuit and the communication port. The processor determines whether the processor is operating in a default configuration, and broadcasts the electronic photosensor information on the communication link if the processor is operating in the default configuration.Type: ApplicationFiled: March 31, 2009Publication date: July 23, 2009Applicant: Lutron Electronics Co., Inc.Inventors: Dragan Veskovic, Robert Anselmo, Audwin W.

Publication number: 20080185977Abstract: A ballast for use in a multi-ballast lighting system wherein the ballasts are coupled together by a digital communication network. The ballast comprises a power circuit portion for providing an electrical current to power a lamp. The ballast further includes a sensor input circuit for receiving at least one sensor input from a sensor device, a processor receiving an input from the sensor input circuit and providing control signals to control the operation of the ballast, and a communication port coupled to the processor and to the communication network for exchanging data. The ballast processor is operative to receive a serial data that has a portion defining whether the message is in a first or a second format, the first format comprising a DALI standard format and the second format comprising a format providing extended functionality. The ballast processor is capable of processing messages in either the first or second formats.Type: ApplicationFiled: April 1, 2008Publication date: August 7, 2008Applicant: LUTRON ELECTRONICS CO., INC.Inventors: Dragan Veskovic, Robert Anselmo, Audwin W.

Patent number: 7142932Abstract: An infrared hand-held remote control for handling a single or plural devices such as lights, shades, drapes and the like contains ergonomically selected and placed control buttons that are self-describing and easy to use. It allows explicit, easy-to-use control of different functions by providing for each function to be controlled vertically disposed discrete buttons that provide “all or nothing” control of some physical feature and similar, vertically disposed and horizontally aligned “adjust” buttons that allow for fine and continuous control of the physical quantities between the extremes or limits of the discrete button functions. Successive groups of buttons provide for the control of different appliances or devices, where each group of buttons is identified by easy to comprehend icon or alphabetic representations. A preset button is also provided for setting and recalling an operational preset value for the device(s) from memory.Type: GrantFiled: December 19, 2003Date of Patent: November 28, 2006Assignee: Lutron Electronics Co., Ltd.Inventors: Joel S.

Publication number: 20040217718Abstract: Systems and methods for providing a load control device, such as a DALI ballast, having an infrared receiver. The load control device resides on a digital communications link and receives infrared commands via a lightpipe. The commands are input to a microprocessor to set an address of the load control device. Addressing the load control device in this manner allows plural control devices residing on a single communications link to be addressed by the same short address. The control devices may be removed and replaced, and the short address and zone assignments of the removed devices may be reassigned to the replacement devices via infrared communication. The load control device may be placed into various modes (e.g., a programming mode or addressing mode) via commands received over the infrared receiver.Type: ApplicationFiled: April 28, 2004Publication date: November 4, 2004Inventors: Russikesh Kumar, Donald Ray Mosebrook, Matthew Skvoretz, Michael A.
