A good analogy to visualize the intrinsic dichotomy of incandescence and luminescence light production mechanism, would be like a fire oven compared to a microwave oven, one heats from the outside to the inside, while the other from the inside to the outside. In the end both produce heat, but through completely opposite ways, and the same applies to light production. Both incandescent and luminescent light sources do have their unique applications and excel in their own areas. For example incandescence is the unmatched champion for high fidelity colors thanks to its broadband spectrum, but bot luminescence, because it is really just a superposition of a handful of frequencies, that may appear white to the mind, but in reality have real spectral voids where there is literally no light there. However this makes luminescence excels in lumen per watt output since a lot of the spectrum is missing, which is useful for lighting spaces that require inexpensiveness, at the expense of spectral wholeness. Luminescence by is also the ideal digital information transmission medium because its spectrum can be further reduced to just a single frequency like in laser, making possible high-speed data transmission through fiber opric without digital data loss, something indispensable for our modern communications. ²
