Patent ID: 11937679

Abstract:
A hair styling device (S), comprising a luminescent unit (LU) for subjecting hair (H) to optical radiation. Preferably, the luminescent unit (LU) is arranged to translate a first wavelength of light (Li) from a light source (L) into a second wavelength of N escaping light (EL) escaping from the luminescent unit (LU). Preferably, light escapes from the luminescent unit (LU) where hair (H) touches the luminescent unit (LU). Preferably, the luminescent unit (LU) is provided with a scattering element. A refractive index of the luminescent unit (LU) may range from 1.3 to 1.7, preferably 1.3 to 1.42. Preferably, the luminescent unit (LU) provides for a plurality C of treatment compartments. The hair styling device preferably comprises a handle having a light source (L) for coupling light (Li) into the luminescent unit (LU), and may be provided with a plurality of exchangeable luminescent units (LU) each adapted for a respective hair styling type, which exchangeable luminescent units (LU) are insertable into the handle.
