1. A lens plate for an LED device, the lens plate comprising:
a plurality of lens elements each having an optical axis, said plurality of lens elements being arranged in a plane perpendicular to the optical axes; and
a flexible connection between a further plurality of two consecutive lens elements of the plurality of lens elements so that a distance and an angle between each of said two lens elements can be adjusted in said plane, and the flexible connection comprising two V-shaped members such that a pitch of said two lens elements is increasable by up to 40%, each of the V-shaped members having first and second arms joined together at a pointed end of each arm to form the V-shape, and each of the V-shaped members being joined between the further plurality of two consecutive lens elements only at a flared end of a corresponding first or second arm, each of the flared ends being opposite the corresponding pointed end on the corresponding first or second arm of each of the V-shaped members;
wherein each of said two lens elements and the flexible connection are made of the same material, and the flexible connection is molded together with the two lens elements.
