1. A light emitter component comprising:

  • a submount comprising a first side having a planar surface area;

    at least first and second electrical contacts disposed on the first side of the submount, wherein a combined surface area of the at least first and second electrical contacts comprises an electrical contact area;

    at least one light emitter chip disposed on the first side of the submount and electrically connected to each of the at least first and second electrical contacts, wherein the at least first and second electrical contacts are disposed on one side of the at least one light emitter chip; and

    an optical element disposed over the at least one light emitter chip, wherein the optical element comprises a first portion that is at an acute angle with respect to the planar surface area of the submount and wherein the at least first and second electrical contacts are positioned below the first portion of the optical element;

    wherein the electrical contact area is less than half of the planar surface area of the first side of the submount; and

    wherein the submount comprises a central axis that divides the submount into a first sectional portion and a second sectional portion, the electrical contact area being fully disposed on either the first sectional portion or the second sectional portion.
