The circuit board is disposed under the upper cover, and connected with the upper cover. The light-emitting elements are mounted on the circuit board. One of the light-emitting elements is electrically connected to a power source to illuminate. The base includes a receptacle for accommodating the upper cover and the circuit board. By rotating the upper cover and the circuit board with respect to the base, another of the light-emitting elements is electrically connected to the power source to illuminate."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Rotatable light source device","description":"A rotatable light source device includes an upper cover, a circuit board, plural light-emitting elements and a base.
