PURPOSE:To provide a rotary lamp which is made small, and improved in warning effect with the increase of used light flux. CONSTITUTION:The second reflector 4 is arranged inward from the first reflector 3. The first reflector 3 is formed in such a shape that two bell structures 5, 5 are cut off at the tops and joined together, the inside faces of the bell structures 5, 5 being shaped into rotational paraboloid. On the other hand, the second reflector 4 is formed by cutting off a bell structure at the top, the inside face being shaped into rotational paraboloid. The second reflector 4, with the focal point matching to the focal point of the first reflector 3, is isolatedly arranged inside the first reflector 3. In addition, a light source 2 made up with a halide lamp, etc., is arranged at the matching focal point. |
