Abstract
A dense array of semiconductor devices having an array of micro-reflectors, the micro-reflectors having characteristics that enhance dense packing of the array in balance with collection and collimation of the array's radiant output.
Claims20
A dense array of light emitting semiconductor devices, the array providing radiant output directed to a work piece, the array comprising:
- a plurality of first micro-reflector elements, each such element having an upper portion, a lower portion and a transition portion disposed between the upper and lower portions, each such element including a packing edge disposed in the upper portion, the packing edge having a perimeter shape, each such element having a basic volumetric form, the cross-section of which volumetric form has a outline that differs from the perimeter shape of the packing edge and wherein, in the transition portion, the cross-section of the volumetric form transitions to provide for the perimeter shape.
A photoreactive system, the system providing radiant output directed to a work piece in association with a photoreaction, the system comprising:
- a light emitting subsystem, the light emitting subsystem including a dense array of light emitting semiconductor devices, the array having a plurality of micro-reflector elements, each such element having an upper portion, a lower portion and a transition portion disposed between the upper and lower portions, each such element including a packing edge disposed in the upper portion, the packing edge having a perimeter shape, each such element having a basic volumetric form, the cross-section of which volumetric form has a outline that differs from the perimeter shape of the packing edge and wherein, in the transition portion, the cross-section of the volumetric form transitions to provide for the perimeter shape.
