At least one luminescent material is provided on each of the two sides of the two-sided luminescent-material wheel, thus both on the front side and on the opposite back side. The luminescent materials on both sides are excited sequentially in time. For this purpose, at least one transmissive region is provided in the rotating luminescent-material wheel, through which transmissive region the excitation radiation can radiate, which excitation radiation can be deflected onto the luminescent material on the back side by means of an optical unit."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Lighting device having phosphor wheel and excitation radiation source","description":"Various embodiments may relate to a lighting device, including an excitation radiation source and a two-sided luminescent-material wheel.
