Claim of US Patent No. 9,583,683

11. A light emitting device having a stack of layers including semiconductor layers comprising an active region, said device
comprising:
a transparent optical element bonded to a surface of the stack by a bonding layer, wherein the bonding layer includes luminescent
material,

wherein a smallest ratio of a length of a base of said optical element to a length of said surface is greater than one, and
wherein the transparent optical element does not extend over sides of the stack of layers.
