In the same field of endeavor, Leung teaches wherein a proximal surface (Convex lower surface; 19B; Fig 17B; ¶[0100]) of the lumiphoric material layer (Luminescent conversion element; 19; Fig 17B; ¶[0100]) is arranged between an opposing, parallel distal surface (Convex upper surface; 19A; Fig 17B; ¶[0100]; Note: The upper surface 19A has a portion parallel to lower surface 19B) of the lumiphoric material layer and the outer surface (Outer surface of LED 103a) of the at least one LED (LED; 103a; Figs 2/17B; ¶[0003]),
and wherein the proximal surface of the lumiphoric material layer has a greater width (Greater width on the parallel portions of 19B than 19A; Fig 17B) than the distal surface; and
wherein a central portion (Central portion of 19; Fig 17B) of the lumiphoric material layer is arranged over the entirety of the outer surface of the at least one LED,
and an average thickness of a peripheral portion (Vertical thickness of outer portions of 19; Fig 17B) of the lumiphoric material is less than an average thickness (Vertical thickness of central portions of 19; Fig 17B) of the central portion of the lumiphoric material.
wherein the lumiphoric material layer overlaps a portion of the fill material layer (Encapsulant material; 14; Fig 17B; ¶[0079]) proximate to a perimeter (Perimeter of LED 103a; Figs 2/17B) of the outer surface of the at least one LED,
with the peripheral portion of the lumiphoric material layer being arranged over a portion (Portion of encapsulant 14 surrounding LED 103a; Figs 2/17B) of the fill material in a region around a perimeter (Region around perimeter of LED 103a; Fig 17B) of the outer surface of the at least one LED.
and wherein the scattering material layer (Third encapsulant material; 17; Fig 17B; ¶[0105]) conforms to lateral boundaries of the peripheral portion (Side surfaces of peripheral portion of luminescent conversion element 19; Fig 17B) of the lumiphoric material layer,
with a portion (Portions of encapsulant 17 on periphery of luminescent conversion element 19; Fig 17B) of the scattering material layer overlapping the peripheral portion of the lumiphoric material layer.
It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Light Emitting Device as disclosed by Camras by using a lumiphoric material layer comprising of a proximal portion having a greater width than a parallel to a distal portion of the lumiphoric material layer, a central portion of the lumiphoric material layer to be arranged over the entirety of the outer surface of the at least one LED, and an average thickness of a peripheral portion of the lumiphoric material is less than an average thickness of the central portion of the lumiphoric material, wherein the lumiphoric material layer overlaps a portion of the fill material layer proximate to a perimeter of the outer surface of the at least one LED, with the peripheral portion of the lumiphoric material layer being arranged over a portion of the fill material in a region around a perimeter of the outer surface of the at least one LED; and wherein the scattering material layer conforms to lateral boundaries of the peripheral portion of the lumiphoric material layer, with a portion of the scattering material layer overlapping the peripheral portion of the lumiphoric material layer, as disclosed by Leung.
One of ordinary skill in the art would have been motivated to make this modification such that substantially all emissions of at least one LED may be absorbed by one or more lumiphoric materials, due to the shape and thickness of the lumiphoric material having a design such that all emissions are captured and a desired perceived color is obtained.
Further, the light travelling through the lumiphoric material which has a proximal surface of greater width than the distal surface would take much shorter time passing through the material by being refracted in a direction closer to the normal of the tangent line along the surface, as suggested by Leung (¶[0093]).
Further, the efficiently coupling the light emitted from the LED to the scattering material layer, it is possible to improve the utilization efficiency of the light emitted from the LED.
Finally, the luminescent conversion element 19 may be chosen or altered to offset and control the path length difference of light rays emitted from the LED which travels through first encapsulant material 14, and the luminescent conversion element 19 must be disposed over the fill material layer proximate to the outer surface of the LED, as the fill material layer defines the lower sidewall 6 of reflector 4 that encompasses the first encapsulant material transmitting the light rays from the LED, as suggested by Leung (¶[0108]).
However, Camras in view of Leung does not teach the lumiphoric material layer being in contact with the outer surface of the at least one LED.

It would have been obvious for one of ordinary skill in the art before the effective filing date of the claimed invention to have modified the Light Emitting Device as disclosed by Camras in view of Leung and Watanabe by making a lens in contact with at least a portion of the scattering material layer, as disclosed by Sano. One of ordinary skill in the art would have been motivated to make this modification such that covering member 40 reflects the light of the sealing member 80 on the surface of the covering member 40 to the outside. Furthermore, by efficiently taking out the light and making the surface of the covering member 40 on the light emitting side a concave surface inclined from the side surface of the light transmitting member 20 toward the substrate 50, the light is diffused and the emitted light of the light emitting device can be oriented in a wide range, as suggested by Sano (¶[0062]).

A shortened statutory period for reply to this final action is set to expire THREE MONTHS from the mailing date of this action. In the event a first reply is filed within TWO MONTHS of the mailing date of this final action and the advisory action is not mailed until after the end of the THREE-MONTH shortened statutory period, then the shortened statutory period will expire on the date the advisory action is mailed, and any nonprovisional extension fee (37 CFR 1.17(a)) pursuant to 37 CFR 1.136(a) will be calculated from the mailing date of the advisory action. In no event, however, will the statutory period for reply expire later than SIX MONTHS from the mailing date of this final action.
