▎ 摘　　要

NOVELTY - A wavelength conversion device (1) comprises a wavelength conversion plate (10) comprising a lateral edge, a surface and a conversion region to receive a light beam and convert a wavelength of the light beam, a reflective layer (20) arranged on surface of the wavelength conversion plate, a driving component (30) arranged proximal to the lateral edge of the wavelength conversion plate and to displace the wavelength conversion plate, and a thermal conductive layer arranged on the surface of the wavelength conversion plate and directly connected to the conversion region for conducting a heat generated at the conversion region during a wavelength conversion. USE - Wavelength conversion device used for fields of illumination sources, and projection displays. ADVANTAGE - The wavelength conversion device has excellent thermal conductive efficiency. DESCRIPTION OF DRAWING(S) - The drawing shows a cross-sectional view illustrating a wavelength conversion device. Wavelength conversion device (1) Wavelength conversion plate (10) Surfaces (11, 12) Reflective layer (20) Driving component (30)
