Abstract
An optical wavelength conversion module including a substrate, a driving device, and a first phosphor material layer is provided. The first phosphor material layer is disposed on a first optical region of the substrate. A conversion beam generated by the first phosphor material layer is a yellowish green beam when a phosphor temperature of the first phosphor material layer is close to or equal to an ambient temperature. The conversion beam generated by the first phosphor material layer is a yellow beam when the phosphor temperature of the first phosphor material layer is close to or exceeds a preset temperature. The driving device is connected to the substrate. The driving device is adapted to drive the substrate to act when the optical wavelength conversion module is in an operating state, so that the yellow beam is emitted from the first optical region. An illumination module is also provided.
