PROBLEM TO BE SOLVED: To provide an indicator which can improve a visibility function and a minimum temperature rise. SOLUTION: This indicator 1 is constituted by disposing a high-intensity light source 4 consisting of a xenon flash lamp capable of flashing inside a case body 2, and providing a luminous material 5 of permeability at the inner surface of an irradiation surface 3 consisting of a transparent member. The light source 4 is formed to be capable of continuous flashing and intermittent flashing at intervals of fixed time as a result of a driving circuit 9 being operated, which is formed to a substrate 8 using a driving power source from a base 11 having lamp-base thread 10. In order to the improve illumination function of the permeable luminous material 5, an impermeable luminous material 7 may be formed at a partition inner surface 6a, and a protective hood involving a lens function may be formed at the irradiation surface 3. For the permeable luminous material 5, in order to obtain an artificial color, a coloring filter consisting a concentric and centrifugal alternate layer or a mesh layer in its combination layout or a fluorescent material may be combined in its irradiating surface direction. |
