The phosphor wheel has a first side on which a phosphor layer is formed. The circulation fan blows an air flow to the phosphor layer. The motor rotatably drives the phosphor wheel. The casing unit houses the phosphor wheel, the circulation fan, and the motor. In the casing unit, a circulation path of the air flow created by the circulation fan is formed. The heat absorber is in the shape of a cylinder. The heat absorber includes a fin structure including a plurality of fins arranged along a radial direction of the casing unit and provided so as to extend in a height direction of the cylinder. The air flow is supplied to the heat absorber to cool the air flow that has absorbed heat generated at the phosphor layer."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light conversion device and projection display apparatus including same","description":"A light conversion device includes a phosphor wheel, a circulation fan, a motor, a casing unit, and a heat absorber.
