An integrated light engine including flexible optics and a flexible light source, and lighting devices including the same, are provided. The integrated light engine includes a flexible light source configured to emit light, and flexible optics coupled to the flexible light source. The flexible optics beam shapes light emitted by the flexible light source. The integrated light engine is capable of entering a set of states, such that a portion of beam shaped light emitted by the integrated light engine in a first state is aimed in a first direction and a portion of beam shaped light emitted by the integrated light engine in a second state is aimed in a second direction. Different combinations of the flexible optics with the flexible light source result in the integrated light engine being able to enter a number of flexed states or being held in a substantially flat, substantially stiff state.

Techniques are disclosed for attaching SMDs to a flexible substrate using conductive epoxy bond pads. Each bond pad includes a set of elongated strips of conductive epoxy that are applied and cured onto the flexible substrate in an adjacent and parallel fashion. The bond pads are used to attach SMDs to the flexible substrate and also provide the conductive contacts for a printed circuit. A circuit may be printed on the flexible substrate using conductive ink that partially covers the bond pads, leaving a portion of the pads exposed. A second layer or strip of conductive epoxy may be applied over and across the exposed portions of the bond pad strips in order to attach an SMD. The number, size, and orientation of the epoxy bond pad strips may be determined by the amount of bending the flexible substrate is expected to withstand and/or the orientation of the bend.


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 luminaires 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.

An accent lamp (10) having a solid state light source (4), such as LEDs, is attachable to a rear surface of an automotive headlamp (40) opposite the light-generating capsule (44). Accent lamp (10) has first retaining member (20), such as a clamp, formed above printed circuit board (8) on which LED (4) is mounted. Headlamp base (60) defines light passageway (45), formed as a light guide (42), extending from outermost peripheral surface (63) to an upper surface (61) on which lamp capsule (44) is retained. Accent lamp (10) is readily detachably mounted to headlamp (40), preferably by resilient first and second retaining members (20, 24), and, when mounted, can be biased to promote optical coupling of light source (4) to light guide (42).

Fault protection circuitry and methodologies for isolated power supply topologies are provided. The circuitry is configured to shut down the primary side of the supply in case of a system fault, while keeping the secondary side circuit running, thus offering flexibility for restarting upon clearing of the fault. A lighting driver thus configured with safety isolation and a secondary side microcontroller or other control circuitry, is configured so that the circuit can shut down the primary side in response to system fault detection, while keeping the secondary microcontroller running from an energy storage circuit (e.g., bulk capacitor in parallel with load). The driver operation can resume with a controlled timing if the fault is cleared. The number of restarts may be limited, and/ or a timer may be used to space restarts. The driver may be used with loads other than lighting-based loads, as will be appreciated.
