WAVELENGTH CONVERSION MEMBER AND LIGHT SOURCE MODULE

A wavelength conversion member includes a substrate, a phosphor layer, and a non-ventilated blade. The substrate is configured to rotate based on an axis. The phosphor layer is disposed on the substrate. The non-ventilated blade has a roughness between 5 μm and 1.25 mm, or a specific surface area of...

Summary:A wavelength conversion member includes a substrate, a phosphor layer, and a non-ventilated blade. The substrate is configured to rotate based on an axis. The phosphor layer is disposed on the substrate. The non-ventilated blade has a roughness between 5 μm and 1.25 mm, or a specific surface area of the non-ventilated blade exceeds a geometric area of the non-ventilated blade by more than 10%.
