20110035404 | METHODS AND APPARATUS FOR FACILITATING DESIGN, SELECTION AND/OR CUSTOMIZATION OF LIGHTING EFFECTS OR LIGHTING SHOWS - Methods and apparatus for facilitating a process of designing, selecting, and/or customizing lighting effects or lighting shows. A library of indexed (tagged) predefined lighting effects or shows is searched by a search engine, based upon information provided by a user/designer, to identify a set of effects or shows having attributes that are in some way related to the information provided by the user. The user is then presented with search results, i.e., a manageable subset of intelligently chosen lighting effects or shows, which may be ranked in terms of relevance, any one or more of which may be readily selected by the user. The user may select one or more effects or shows from the search results “as is” for execution by a lighting system, may combine one or more effects or shows from the search results, or may modify one or more effects or shows from the search results to refine some aspect of the effect(s)/show(s) in accordance with user preferences. In one exemplary implementation, the library of lighting effects/shows and/or the search engine may be hosted by a web site and accessible via the Internet. | 02-10-2011 |
20130169159 | Solid-State Lighting Apparatus and Methods Using Parallel-Connected Segment Bypass Circuits - A lighting apparatus includes a plurality of light emitting diode (LED) sets coupled in series. The apparatus further includes a bypass circuit coupled in parallel with one of the LED sets and configured to sense and control a bypass current when the one of the LED sets is in a first bias state and to attenuate the bypass current responsive to a transition of the one of the LED sets to a second bias state. The first bias state may be substantially non-conducting and the second bias state may be conducting. The apparatus may include a plurality of such bypass circuits, respective ones of which are coupled in parallel with respective ones of the LED sets such that the bypass circuits are coupled in series. | 07-04-2013 |
20140084801 | ACTIVE CURRENT LIMITING FOR LIGHTING APPARATUS - A lighting apparatus, such as an LED lighting apparatus, includes at least one light-emitting device, a rectifier circuit having an input configured to be coupled to an AC source, and a driver circuit coupled to an output of the rectifier circuit and to the at least one light emitting device. The apparatus further includes an active current limiter circuit coupled to the output of the rectifier circuit and configured to limit a current provided to the driver circuit, such as a current drawn by an EMI filter of the driver circuit, which may cause erratic operation of a dimmer controlling the lighting apparatus. | 03-27-2014 |
20140265886 | LIGHTING APPARATUS AND METHODS USING SWITCHED ENERGY STORAGE - A lighting apparatus includes a string of serially-connected light-emitting devices including at least a first segment and a second segment and a control circuit configured to control a relationship of light outputs of the first segment and the second segment by diverting current from a node of the string to at least one energy storage device and subsequently transferring energy from the at least one energy storage device to at least the first segment. The control circuit may be configured to divert the current responsive to a control input, such as a temperature and/or a dimming level. The at least one energy storage device may include at least one inductor. In some embodiments, the control circuit may control at least one color characteristic of light produced by the string. | 09-18-2014 |

20100231133 | APPARATUS FOR CONTROLLING SERIES-CONNECTED LIGHT EMITTING DIODES - An apparatus for controlling an LED-based lighting system includes a comparison circuit configured to compare at least one signal representative of a supply voltage with at least one other signal representative of a series voltage drop over at least some of a plurality of LEDs connected electrically in series. The apparatus includes a controller, connected to the comparison circuit; and a power section connected to the controller. The power section is configured to operate at least one switch such that the number of LEDs operated in series may be changed in response to the comparison circuit. | 09-16-2010 |

20120310703 | TARGETED CONTENT DELIVERY USING OUTDOOR LIGHTING NETWORKS (OLNs) - This invention describes a system and method to provide a service to advertisers and businesses that enables adaptation of advertising priorities using information collected by a lighting infrastructure. The system uses outdoor lighting networks to manage/control data sensors connected to a network, e.g. hosted at lighting units. This invention enables new business scenarios where operators and/or owners of the city's lighting infrastructure can provide a value added service or generate revenue from ad providers and local businesses by leveraging the data acquired through the lighting and adjacent infrastructure (e.g. sensors) to help the businesses to increase their advertising performance/targets; particularly, with respect to Location Based Services (LBS). | 12-06-2012 |
20140192527 | INTEGRATED LED-BASED LUMINAIRE FOR GENERAL LIGHTING - Lighting apparatus and methods employing LED light sources are described. The LED light sources are integrated with other components in the form of a luminaire or other general purpose lighting structure. Some of the lighting structures are formed as Parabolic Aluminum Reflector (PAR) luminaires, allowing them to be inserted into conventional sockets. The lighting structures display beneficial operating characteristics, such as efficient operation, high thermal dissipation, high output, and good color mixing. | 07-10-2014 |

20100222002 | RADIO-COMMUNICATION MODULE COMPRISING EMISSION MEANS CONTROLLED BY INTERFERENCE DETECTION MEANS AND CORRESPONDING DEVICE AND USE - A radiocommunication module is provided, which includes a transmitter with a first mode of communication in at least one first frequency band. The module also includes: an interference detector for emitting a warning signal if interference is detected; and a controller for controlling the transmitter in such a way that it is able to switch between the first mode of communication and a second mode of communication which is different from the first mode, if the interference detector emits the warning signal. | 09-02-2010 |
20120170754 | METHOD FOR DETECTING THE SCRAMBLING OF A RADIOCOMMUNICATION NETWORK, AND CORRESPONDING STORAGE MEANS AND CIRCUIT - A method is provided for detecting scrambling of a radiocommunication network. The method is applied by a radiocommunication circuit capable of being connected to the network by being synchronized on a radiocommunication channel. The method includes a final detection phase, having the following steps: detection of verification of the following final condition: there are N radiocommunication channels on which the radiocommunication circuit cannot be synchronized despite detection of a power level normally sufficient for being synchronized, where N>2; and if the final condition is verified, generation of a final scrambling signal with a probability of scrambling equal to 100%. The method also includes at least one intermediate detection phase, having the following steps: detection of verification of at least one intermediate condition; and if the at least one intermediate condition is verified, generation of an intermediate scrambling signal with a probability of scrambling of less than 100%. | 07-05-2012 |
