The light source generating device includes a first light source, an auxiliary light source, a control device, a driver and a current command generator. The first light source generates a first light beam. The auxiliary light source generates an auxiliary light beam corresponding to the first light beam. The control device generates a first driving signal to drive the first light source. The driver generates an auxiliary driving signal to drive the auxiliary light source according to the gate control signal and a current command. The current command generator receives an indication signal, and generates the current command according to the indication signal, wherein the indication signal corresponds to a driving current of the first light source. The invention has an effect of enhancing brightness/chrominance."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Light source generating device, projection apparatus and light source generation method thereof","description":"A light source generating device, a projection apparatus and a light source generation method are provided.
