  • Patent number: 10321528
    Abstract: 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).

  • Patent number: 9491836
    Abstract: Methods and apparatus for determining the relative electrical positions of lighting units (202a, 202b, 202c, 202d) arranged in a linear configuration along a communication bus (204) are provided. The methods may involve addressing each lighting unit (202a, 202b, 202c, 202d) of the linear configuration once, and counting a number of detected events at the position of each lighting unit. The number of detected events may be unique to each electrical position, thus providing an indication of the relative position of a lighting unit within the linear configuration. The methods may be implemented at least in part by a controller (210) common to multiple lighting units of a lighting system, or may be implemented substantially by the lighting units (202a, 202b, 202c, 202d) themselves.

  • Patent number: 8938468
    Abstract: 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.

  • Patent number: 8736197
    Abstract: A lighting apparatus (100) includes one or more first LEDs (202) for generating a first spectrum of radiation (503), and one or more second LEDs (204) for generating a second different spectrum radiation (505). The first and second LEDs are electrically connected in series between a first node (516A) and a second node (516B), between which a series current (550) flows with the application of an operating voltage (516) across the nodes. A controllable current path (518) is connected in parallel with one or both of the first and second LEDs so as to at least partially divert the series current, such that a first current (552) through the first LED(s) and a second current (554) through the second LED(s) are different. Such current diversion techniques may be employed to compensate for shifts in color or color temperature of generated light during thermal transients, due to different temperature-dependent current-to-flux relationships for different types of LEDs.
