1. A light emitting device, comprising:

  • at least one light emitter; and

    an encapsulant arranged such that substantially all light that is emitted from said at least one emitter passes through said encapsulant, said encapsulant having light scattering properties that vary spatially in relation to the emission angle of light propagating through said encapsulant.
