ABSTRACT:
A lighting arrangement comprising: a light reflective enclosure; at least one radiation source housed within the enclosure and operable to generate excitation light of a first wavelength range; a substantially spherical optical component mounted over the enclosure opening and at least one phosphor operable to absorb at least a portion of the excitation light and to emit light of a second wavelength range, wherein light generated by the arrangement comprises the combined light of the first and second wavelength ranges and wherein the at least one phosphor material is provided as a layer on at least a part of the surface of the optical component that is enclosed within the volume of the enclosure when the component is mounted to the enclosure.
