Abstract: Techniques are disclosed for projecting visible cues to assist with light-based communication (LCom), the visible cues referred to herein as visual hotspots. The visual hotspots can be projected, for example, using a luminaire that may be LCom-enabled. The visual hotspots may be projected onto the floor of an area including an LCom system. The visual hotspots can be used for numerous benefits, including alerting a potential user that LCom is available, educating the user about LCom technology, and assisting the user in using the LCom signals available in the area. The visual hotspots may include images, symbols, cues, characters (e.g., letters, words, numbers, etc.), indicators, logos, or any other suitable content. In some cases, the visual hotspots may be interactive, such that a user can scan the hotspot to cause an action to occur (e.g., launch an application or website).

Abstract: Techniques are disclosed for enhancing indoor navigation using light-based communication (LCom). In some cases, an LCom-enabled luminaire configured as described herein may acquire user data from a local computing device and relay it to a server that tracks and analyzes the data to assess statistics for the luminaire's local spatial environment. The disclosed luminaire may receive from a local computing device a request for indoor navigation to a target of interest, such as a remote computing device. The luminaire may relay that request to a downstream luminaire, which delivers the request to the target. The target may respond with data that allows for tracking of its location and indoor navigation thereto, regardless of whether that target is moving or stationary. In a network of such luminaires, data distribution via inter-luminaire communication may be provided, for example, via an optical interface or other wired or wireless communication.

Abstract: Active proximity based wireless network commissioning is provided. Routers and end devices are placed in a default mode before commissioning such that the devices are communicative but do not transmit join requests. A commissioning device is positioned at a selected location and transmits a wireless beacon request that is received by devices within a limited range. Routers, end devices and coordinator devices within range send response beacons. The response beacons are used by the commissioning device to discover devices and select network parameters for the discovered devices. The commissioning device uses the parameters to prompt the coordinator device to form a network and prompt the qualified device to enter a pending mode and join the network.

Abstract: Techniques are disclosed for providing an adaptive and scalable output drive current by a lighting driver, which helps mitigate issues related to binning of solid state light sources. The disclosed techniques may be implemented, for example, with the use of header pins and one or more jumpers or so-called shunt connectors. This allows for a given driver with a constant current output to provide any number of desired output drive currents on demand, by switching and/or adding and/or removing one or more shunt connectors across the appropriate header pins. The header may include any number of pin-pairs, with each pin-pair capable of receiving a shunt connector. Any number of driver topologies may be implemented with the header, such as flyback, buck, boost, buck-boost, and variants thereof.

Abstract: Techniques for supplying auxiliary power to AC powered lighting devices are disclosed. An auxiliary power supply can be used, for example, to provide auxiliary power to lighting control circuitry, an LED driver, or any other electronic lighting device. In some example embodiments, the linear regulator is connected to a switch that is controlled by a control circuit such that the linear regulator operates only when the instantaneous line input voltage is in a certain range where the linear regulator has a somewhat good efficiency. In such cases, when the linear regulator is operating, energy is stored with an auxiliary capacitor connected to the output of the linear regulator. In some embodiments, the linear regulator is configured to operate only when the line voltage is between a determined upper and lower voltage threshold; while in other cases the linear regulator is configured to operate only when the line voltage is increasing through the predetermined voltage threshold values.

Abstract: Solid state lighting systems are disclosed for providing uniform brightness of LEDs serially connected in a string. In some embodiments, the LEDs can be powered directly from the mains such that no switch-mode power supply or the output storage elements associated therewith are needed. In some such cases, a linear regulator and switches can be used to control the current through the LEDs to provide uniform brightness. Other embodiments can be used with a switch-mode based driver topology and/or storage elements coupled in parallel with clusters of the LEDs. In any such cases, control logic (e.g., microcontroller or other suitable controller) can be used to control the switches accordingly to provide uniform brightness, and in some cases, to mitigate the implications of having no SMPS output storage element. In some embodiments, the switching pattern provided by the control logic is random, although other switching patterns can be used.
