Claims

[Scope of utility model registration request]

In a self-luminous indicator light in which a transparent or semi-transparent indicator tube 4 is provided at the upper end of a support column 1 that includes a built-in power source 2, and a light emitting section 3 is provided within the indicator tube 4, the light emitting section 3 is mounted on a substantially horizontal substrate. A plurality of light emitting diodes 6, 6... are arranged on the substrate 5 at predetermined intervals at least in the circumferential direction of the substrate 5, and each light emitting diode 6, 6... is oriented in a substantially vertical direction and blinks. A cone-shaped reflecting plate 7 is placed above the light emitting diodes 6, 6... with its top facing downward and facing approximately the center of the substrate 5, and the reflecting surface 71 of the reflecting plate 7 is inwardly shaped like a paraboloid. A self-luminous indicator light that is curved into a planar shape and has a large number of unevenness 41, 41, . . . provided on the inner circumferential surface of an indicator tube 4.
