1. An LED module comprising:
a printed circuit board having an upper surface, a lower surface, and a side surface; the printed circuit board comprising a first layer; a second layer; and a plurality of LEDs adapted to output light from the upper surface; and
an optically transmissive cover plate positioned to cover at least one of the plurality of LEDs and having at least one protrusion arranged to cover a portion of an interface between the first layer and the second layer at the side surface of the printed circuit board,
wherein the first layer forms the lower surface of the printed circuit board, and comprises a first layer side surface that is at least partially inwardly inclined.
