Abstract

An optical-wavelength converting wheel component comprises a motor (1) and an optical-wavelength converting wheel (2). The optical-wavelength converting wheel (2) comprises an optical-wavelength converting material layer (21) and at least one functional layer adjacent to the optical-wavelength converting material layer (21), particularly the optical-wavelength converting wheel (2) further comprises at least one spacing layer (26), which is a thin gap spaced between the location of the optical-wavelength converting material on the optical wavelength converting material layer (21) and the functional layer, arranged between the optical-wavelength converting material layer (21) and the functional layer. Brightening can be realized in low cost by means of adopting a light source comprising the optical-wavelength converting wheel component.
