Abstract: A lighting strip has a printed circuit board with one or more perforated lines at which the printed circuit board length may be adjusted by breaking off an end portion of the printed circuit board. A first layer has a first set of conductive tracks and a second layer has a second set of conductive tracks corresponding to the first set of conductive tracks. Each conductive track of the second set is vertically aligned and positioned over the corresponding conductive track of the first set. An array of contact terminals is provided on a third layer. A plurality of lighting elements is disposed along the lighting strip, each electrically connected to a respective pair of the contact terminals. The lighting strip further comprises a set of vias connecting each conductive track of the first set to the corresponding conductive track of the second set.

Abstract: :A lighting device comprises multiple modules each having an array of LED chip connection pads. Interconnections between the pads provide groups of connection pads, each group comprising a parallel set of connection pads, and the groups being in series witheach other. An optical unit is provided for shaping the light output from LED chips mounted on the pads. The groups are defined to minimize an overall spacing of the pads within the groups (in combination) to provide a best possible color mixing for the LEDs mounted on the connection pads.

Abstract: A lens plate has an array of lenslets. A first surface comprises a plurality of individual cells, each cell delimiting one side of a respective lenslet of the array. A second opposite surface comprises a set of grooves, each groove delimiting a second, opposite side, of a sub-array of the lenslets of the array of lenslets. The array of lenslets is a circular array comprising a plurality of concentric rings. Each ring comprises a plurality of straight segments, and each segment comprises multiple said lenslets arranged in a row. The lens plate design thus combines grooves on one side which cover multiple lenslets and a cellular lens structure on the opposite side.
