Abstract: A lighting device comprising a carrier board and an array of lighting elements mounted on the carrier board. The carrier board has a generally spiral shape and the carrier board can be tessellated with one or more identical other carrier boards with windings interleaved with each other. This enables multiple carrier boards to be formed from a single substrate with little or no waste of material. Different designs enable two, four or even more different identical carried board shapes to be tessellated together.

Abstract: A lens (1) comprising a centrally extending axis (A) being perpendicular to a lens axis (L) of the lens, the lens being adapted for retracting light rays from a light source positioned off-axis with respect to the centrally extending axis, the lens comprising a first plurality of slits (21, 22, 23, 24) extending entirely in an interior of the lens and comprising a length (l) extending perpendicular to the centrally extending axis, a width (w) extending parallel to the centrally extending axis and a thickness (t) extending perpendicular to both the length and the width, the first plurality of slits being mutually parallel and covering between 40% and 60% of a plane in which both the centrally extending axis (A) and the length (l) and width (w) of the first plurality of slits (21, 22, 23, 24) extend.
