Abstract: Linear lighting using light-emitting diode (LED) light engines is disclosed. The linear lighting includes a printed circuit board (PCB) with a number of LED light engines disposed on it. A light guide is disposed on the PCB adjacent to the LED light engines. The light guide accepts the light from the LED light engines in a first location and is arranged to emit the light at a desired position that is spaced from the first location. By lengthening the optical path, the light guide may spread the emitted light and provide a more uniform appearance for the linear lighting.

Abstract: Linear LED lighting is disclosed. The linear LED lighting includes a flexible PCB on which a number of LED light engines are disposed, typically at a regular pitch. The PCB is surrounded by a flexible, translucent covering, which may be a plastic, such as poly(vinyl chloride) (PVC). The coating may include an additive that diffuses the light, or have a coating with that additive that does so. Exemplary additives include beads, microspheres, fibers, or other particles of glass and silica, as well as plastics like poly(methyl methacrylate), polycarbonate, and poly(ethylene terephthalate).

Abstract: A strip of linear lighting with distributed power conversion is disclosed. The linear lighting includes a flexible PCB. The flexible PCB is divided into repeating blocks, which are arranged electrically in parallel with one another between power and ground. Each repeating block includes power conversion and conditioning circuits. A plurality of LED light engines are connected to the outputs of the power conversion and conditioning circuits, electrically in series with one another. The power conversion and conditioning circuits typically include at least a full-bridge rectifier, and a filter may be connected to each of the LED light engines. A pair of conductors run the length of the PCB adjacent to it and are connected to each of the repeating blocks. A flexible, transparent covering surrounds the PCB and pair of conductors.

Abstract: Linear LED lighting is disclosed. The linear LED lighting includes a flexible PCB on which a number of LED light engines are disposed, typically at a regular pitch. The PCB is surrounded by a flexible, translucent covering, which may be a plastic, such as poly(vinyl chloride) (PVC). The covering has a light modifying property or effect, typically lensing, diffusion, or a combination of the two. For example, the covering may form a plano-convex or plano-concave lens, or it may form a prism. Additionally or alternatively, the coating may include an additive that diffuses the light, or have a coating with that additive that does so. Exemplary additives include beads, microspheres, fibers, or other particles of glass and silica, as well as plastics like poly(methyl methacrylate), polycarbonate, and poly(ethylene terephthalate). In some embodiments, the covering may be mechanically modified to diffuse light, e.g., by an impressed pattern or by abrasion.
