I might be mistaken. I thought he sad a single light wave could be thought of as an infinite number of rays and propergates through space as a wave.

This is not what most people would interpret as the duality of light.
The photoelectric effect shows that light must have mass and momentum just as a particle.
The interference shows that it must be a wave.
These are the dual properties of light.
Huygens principle applies to all waves, not just light and it is a property of a pure wave.

de Broglie, in 1923, came up with the idea that matter might have a wave-particle duality.
He combined Einstein's energy-mass relationship (E = mc²) with Planck's equation for photon energy (E = hf) ...
E= hf = hc/λ
hc/λ = mc²
λ = h/mc .......... by analogy de Broglie proposed that any particle with mass (m) moving with a velocity (v) moves in some ways like a wave ... with a wavelength λ = h/mv.

No - Huygens idea was that light is a wave - and contradicted Newton's idea that light is a particle - which held up his theory somewhat - only when Young obtained interfernce with his double slit experiment were light waves accepted. It took Planck, Einstein and de Broglie amongst others to show that light could act as both a wave and a particle - ( so Huygens and Newton were both right!)
