1. A flashlight, comprising:
a lens assembly including an adjusting element; and
a light source assembly arranged at a side of the lens assembly, the light source assembly including a first light source, a second light source, an excitation element, and a light-path adjusting element,
wherein the first light source and the excitation element are located at one side of the light-path adjusting element and the second light source is located at another side of the light-path adjusting element, light beams emitted by the first light source are incident onto the excitation element to generate first excitation light, and light beams emitted by the second light source pass through the light-path adjusting element and then are incident onto the excitation element to generate second excitation light, and beams of the first and second excitation lights are outputted simultaneously after passing through the light-path adjusting element and the adjusting element in sequence.
