Abstract:
A lighting fixture, including a bus printed circuit board that receives power from an external source, may be configured with programmable drivers. The bus printed circuit board has mechanical features for receiving the programmable drivers to mechanically mount the programmable driver to the bus printed circuit board. Each programmable driver may have a set of spring contacts positioned to engage exposed pads of the bus printed circuit board when the programmable driver is mounted to the bus printed circuit board, to supply power to the programmable driver. The lighting fixture further includes one or more light sources driven by the programmable drivers.

A top surface of the first base forms a fillister connecting to outside, the first conductor is clamped on the first base and electrically connects the first circuit board to outside. The second circuit module includes a second circuit board and a second connecting housing, the second connecting housing includes a second base connected to a side of the second circuit board and at least one second conductor. A protruding part protrudes from an outer side of the second base, the second conductor is clamped on the second base and electrically connects the second circuit board to outside.
Abstract:
A light emitting module includes a circuit board having a plurality of reflective portions arranged in one direction and connection portions connecting the plurality of reflective portions, light emitting devices mounted on the plurality of reflective portions, and lens units disposed to cover the light emitting devices within boundaries of surfaces, of the plurality of reflective portions, on which the light emitting devices are mounted. A width of each of the connection portions in the other direction, perpendicular to the one direction thereof, is smaller than a diameter of each of the lens units, thus reducing a generation of a dark portion.
Abstract:
A multilayer circuit board assembly includes one or more radio frequency (RF) interconnects between different circuit layers on different circuit boards which make up the circuit board assembly. The RF interconnects can include one or more RF matching pads which provide a mechanism for matching impedance characteristics of RF stubs to provide the RF interconnects having desired insertion loss and impedance characteristics over a desired RF operating frequency band. The RF matching pads allow the manufacture of circuit boards having RF interconnects without the need to perform any back drill and back fill operation to remove stub portions of the RF interconnects in the multilayer circuit board assembly.
Abstract:
A light engine with a heat sink having a curved recessed cavity that receives a flexed or cupped PCB bearing a plurality of LEDs. Once situated within the cavity and released, the PCB has a tendency to return to its flat state, but flanges or other suitable mechanisms at the ends of the cavity restrain the edges of the PCB and prevent the PCB from returning to its flat state. In this way, the PCB is securely retained within and biased against the cavity by its own forces. As the PCB heats, the PCB expands, further biasing the PCB against the cavity of the heat sink and increasing the thermal conductivity between the two components.
Abstract:
Devices comprising multiple flexible substrates bearing OLEDs are provided. The flexible substrates are interconnected, and the properties of the substrates and the interconnections provide the shape of the device.
Abstract:
Disclosed are a method and system to reduce impedance of printed circuit boards through an interconnecting of printed circuit boards using a square wave pattern of plated-through holes. A method of connecting a first printed circuit board to a second printed circuit board comprises forming a square wave pattern of the first printed circuit board and the second printed circuit board and adjoining the first printed circuit board and the second printed circuit board. The method also involves producing plated-through holes along the square wave pattern, a top section, and/or a bottom section of the adjoined first printed circuit board and second printed circuit board. The method further involves securing the top section and the bottom section using a first metal clip and a second metal clip, respectively, and connecting the first printed circuit board to the second printed circuit board by a wave soldering process.
