A known limitation of modern day emittive lighting is that it does not produce a smooth black-body colour spectrum, instead having discrete emission spikes. This can lead to poor colour rendering and Human discomfort.
Moving the emmission source at high speed causes the perceived frequency and therefore
colour of the emitted light to increase or decrease depending if the light source is advancing or receeding.
A large number of emitters are mounted on the edge of a wheel. The wheel is spun at very high speeds. Some of the emittors will be advancing towards the viewer, some away, and some perpendicular to.
This should produce a smeared emission spike.
Two contra-rotating wheels will ensure that there is not red and blue shadows cast from opposite sides of the wheel.
The enclosure needs to be transparent, to allow the light out, but has to be strong enough to contain the disintegration of the wheel which would need to spin at ridiculously high speeds.
Also the design of the electrical connections needs a bit of work.

sp. "emissive"? Or something else entirely? |

To get a 1% frequency change, (assuming a 1m diameter light unit) you need to rotate at about 1,000,000 rev/sec. Surprisingly, that's close to achievable. The (macroscopic) record is for a tiny piece of graphene doing just that.
Rather than rotating the lights themselves, could you spin a mirror (or even a rough/specular surface) to get the scattered light shifting instead? |

I honestly don't know. Could you? Does the mirror count as an emitter for the purpose of doppler frequency and wavelength shifting? I am thinking it probably does. |
