Abstract
A composite lens arrangement for use with a light emitting source directed along an optical axis includes a collimator lens, a beam former lens, a first optical structure, and a member. The collimator lens includes a light collection surface axially opposed to the light emitting source, and an opposite facing light emitting surface. The beam former lens is spaced axially from the light emitting surface, and includes a light collection face axially opposed to the light emitting surface and an opposite light emitting face. The first optical structure is integral to one of the light emitting surface and the light collection face. The member is radially spaced from the optical axis, and extends between, and is attached to, the light emitting surface and the light collection face.
