Further, even when the signal lamp is viewed from the traveling direction of light, as shown in FIG. 16, although the light is diverged by the globe 23, a light spot 32 corresponding to the LED 25 is formed. In addition, although the central portion of the spot 32 is bright, it is dark as a whole and there is a problem that desired brightness cannot be obtained.

The present invention has been made to solve the above-mentioned problems, and uses a light-emitting element that constitutes an LED as a light source to emit light so that the entire globe becomes bright and to check from all angles. It is an object of the present invention to provide a signal lamp capable of operating.

[0017]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, in the signal light according to claim 1, the signal light is provided with a light source and a globe surrounding the light source, and the light emitted from the light source passes through the globe and diverges. The light source covers the light emitting element on the substrate, a plurality of light emitting elements formed on the surface of the substrate, a circuit network for controlling blinking operation of the plurality of light emitting elements, and the surface of the substrate. And a coating film that diffuses the light emitted from the light emitting element inside and diverges it outside.
