A lighting device including: at least one light emitter, at least one light source, and at least one light conductor arranged to conduct light from the light source to the light emitter; the light emitter including a translucent body and a first reflector, the first reflector being connected to or integral with the translucent body; the translucent body including a first emitter portion, a first incident portion, and a spherically curved surface, the spherically curved surface defining a first emitter lens of the first emitter portion and a first incident lens of the first incident portion; the first incident portion being arranged to conduct light emitted from an emission surface of the light conductor, via the first incident lens, to the first reflector; the first reflector being arranged to reflect the light emitted from the emission surface of the light conductor to exit the light emitter as a beam of light via the first emitter lens; wherein the light emitter is rotatable with at least two degrees of freedom relative to the light conductor to direct the beam; and wherein the light emitter is spaced apart from the light conductor to define a separation distance between the emission surface and the first incident lens, the separation distance being selected relative to a distance between the light emitter and a target surface so that the first incident lens and first emitter lens form a conjugate imaging system with a target plane at the target surface and an object plane at the emission surface of the light conductor; and wherein either (i) an adjustment means (60, 62) is provided for varying the separation distance, or (ii) a variable focus optical element is arranged between the first incident lens and the object plane at the emission surface; and further including at least one of feature and feature, wherein: in accordance with feature an object is arranged between the light conductor and the light emitter, and the lighting device is arranged to project an image of the object onto the target surface; and in accordance with feature the light conductor has a cross section which defines a cross sectional shape of the beam, and the lighting device is arranged to project a correspondingly shaped, sharply defined pool of light onto the target surface. the light emitter including a translucent body and a first reflector, the first reflector being connected to or integral with the translucent body;
