    Abstract: A reflective laser activated remote phosphor (LARP) package comprising: a phosphor platelet oriented in a first plane defined by an x-y plane; a laser diode (LD) positioned to be offset along the x-axis from the phosphor platelet and above the first plane along a z-axis perpendicular to the x-y plane, the LD comprising: an output facet configured for emitting a laser beam (LB), the LB comprising: a slow axis oriented in a first direction along which the LB diverges at a first angle; and a fast axis oriented in a second direction along which the LB diverges at a second angle greater than the first angle; wherein the LD is oriented such that: the LB is bisected by the phosphor platelet such that the slow axis of the LB lies in an x-z plane and the fast axis of the LB is perpendicular to an x-z plane.

    Abstract: A rectifying circuit is provided, which includes a first channel circuit, a comparator circuit, and a second channel circuit. The first channel circuit rectifies a first input signal using a transistor that is coupled between an input of the first channel circuit and a node. The comparator circuit is coupled with the transistor and controls it based on a difference between a representative voltage of the first input signal and a representative voltage of the node. The second channel circuit rectifies a second input signal using a diode coupled between an input of the second channel circuit and the node. The transistor may be a first MOSFET and the comparator circuit may be coupled with the first MOSFET by way of a second MOSFET. The second MOSFET controls the first MOSFET and is itself controlled by the comparator circuit.

    Abstract: A network power distribution system includes a plurality of networked digitally controlled lighting devices and a network powered network controller. Each of the digitally controlled lighting devices includes a device driver that coupled to the network. The device driver is selectively transitionable between a first operating mode in which the device driver provides a first voltage and a first current to the network and a second operating mode where the driver does not provide a voltage or current to the network. The network controller autonomously determines a number of device drivers that, in the first operating mode, at least meet the current draw of the network controller. The network controller then transitions the determined number of device drivers to the first operating mode. The network controller monitors the device drivers for faults and autonomously swaps device drivers to maintain network power.

    Abstract: A light weight lighting module and devices including the same are disclosed. The module includes a printed circuit board with a first side and a second side, each including a conductive layer disposed thereon. The printed circuit board also includes thermal vias disposed therein, in thermal contact with the conductive layers on the first and second sides. One or more light sources are attached to the first side of the printed circuit board, such as high power light emitting diodes or laser light sources. A heat sink is attached to the second side of the printed circuit board. The light source(s) and heat sink are in thermal contact with the thermal vias of the printed circuit board so that thermal energy from the light source(s) can be transferred to the heat sink. The thermally-conductive layers and heat sink remain electrically isolated from the light source(s).
