Abstract
A cooling structure includes a phosphor unit, air-blowing systems that cause cooling air to flow, and a duct structure. The phosphor unit includes a substrate and a phosphor that is formed on the substrate and that emits fluorescent light when irradiated with excitation light. The duct structure guides the cooling air blown from the air-blowing systems to the phosphor unit.
