Abstract: An assembly and a method is provided where the LED module includes a plurality of module units interconnected between common connection lines in a sequential order with increasing distances towards a connection terminal of the LED module. The circuit assembly includes an output terminal having a first output terminal portion and a second output terminal portion, a main power supply for supplying an operation voltage potential to a first output terminal portion, a control device for generating a pulse width modulation signal, and an electronic switch coupled to the control device and configured to obtain the pulse width modulation signal and arranged to connect and disconnect a second output terminal portion to/from a reference potential in accordance with the pulse width modulation signal, such as to supply a pulse width modulated voltage to the output terminal. A pulse shaping unit is coupled to the control device.

Abstract: Lighting devices, and methods of manufacturing the same, are provided. A lighting device includes a cover through which emitted light passes and a formed flexible light engine. The formed flexible light engine is placed within a housing, or serves as the housing itself. An interface couples to cover to the housing or the formed flexible light engine. The formed flexible light engine includes a flexible substrate and a plurality of solid state light sources located thereon. The plurality of solid state light sources are configured to emit light through the cover. The formed light engine has a defined shape created during the forming process. This enables placement on the housing within the lighting device, or contributes to the overall shape of the lighting device.
