Abstract
A lighting arrangement comprises: a hollow substantially cylindrical optical component; a plurality of light emitting diodes disposed along the axis of the optical component and operable to generate light of a first wavelength range and at least one phosphor operable to absorb at least a portion of the light emitted by the light emitting diodes and to emit light of a different wavelength range, wherein light generated by the arrangement comprises the combined light emitted by the light emitting diodes and at least one phosphor. The at least one phosphor can be provided as a layer on at least a part of the inner and/or outer curved surfaces of the optical component or incorporated within the optical component.
