Abstract
A wavelength conversion component includes a substrate, a reflection layer, and a phosphor layer. The reflection layer is disposed on the substrate and extends along a first direction. The reflection layer has a top surface that is away from the substrate. The top surface has a height variation on a second direction that is perpendicular to the first direction along the first direction. The phosphor layer is disposed on the reflection layer. The phosphor layer has a thickness variation on the second direction along the first direction. A ratio of the height of the top surface and the thickness of the phosphor layer increases and decreases reciprocally along the first direction.
