Patent ID: 7863642

Claim:
A light source which is electrically accessible after combining with a lens, the light source comprising: a) a light emitting die in the form of a light emitting diode (LED) chip having a light out-coupling side with a contact pad; b) a functional element mounted with an inner surface on said light out-coupling side and comprising a provision for electrically contacting the contact pad, said provision being selected from the group consisting of: a slit-shaped opening extending from a point substantially centrally located over said light out-coupling side to an outer edge of said functional element, and an opening formed at a point substantially centrally located over said light out-coupling side between at least two parts of the functional element joined together over said light out-coupling side forming said provision due to a mating open area in said functional element when said at least two parts are joined together, wherein a first amount of unconverted light from said light out-coupling is mixed with a second amount of converted light coming through said functional element; and c) a contact wire running through the provision of the functional element and connected to the contact pad; wherein said provision for electrically contacting the contact pad of said light emitting die is accessible by exposure of said contact pad of said light emitting die through said functional element after combinational mounting of said functional element to said light emitting die on said light out-coupling side.
