This warning light required a large power source because it was equipped with a high-power incandescent bulb and a rotating reflector.

Additionally, the applicant has already filed an application for a warning light in which a plurality of luminous bulbs are arranged in a ring at the center inside a concave mirror without using a rotating light (see Utility Model Application No. 1981-9281). (c) Problems to be solved by the invention The above-mentioned warning light equipped with a rotating light requires a large power source, so a commercial power source and a large battery must be prepared, and it cannot be used in remote mountainous areas. It was not suitable for

In addition, a warning light that does not use a rotating light but has multiple luminous bulbs arranged in a ring at the center inside a concave mirror does not have a rotating reflector, so power consumption is reduced by using a rotating light. It costs less than that. However, this warning light is not equipped with a reflector that has a reflective surface with many minute irregularities, and when the luminous bulb is off, there is no warning effect at all, and in some cases In some cases, there was even the possibility that they could become dangerous.

The present invention was made in view of the problems of the conventional technology, and aims to realize a safe warning light that consumes less power and has a high warning effect. (d) To solve the problems. The present invention is a warning light, and includes a reflecting mirror having a reflecting surface in which a large number of minute unevennesses are formed on the inner center of the concave mirror, the uneven reflecting surface facing the reflecting surface of the concave mirror. The device is characterized in that the light emitting bulb is fixed to the uneven reflecting surface.

(E) Effect In the present invention, a reflecting mirror having a reflecting surface on which a large number of minute unevennesses are formed is attached to the inner center of the concave mirror so that the uneven reflecting surface faces the reflecting surface of the concave mirror. , a luminous bulb is fixed to the uneven reflective surface. Therefore, a part of the light rays emitted from the luminescent sphere is reflected by the concave mirror and irradiated forward, and the rest is diffusely reflected by the uneven reflecting surface, and then reflected by the concave mirror and irradiated forward. .

Further, when the luminous bulb is off, the light rays emitted from the headlights of a car or the like are reflected by the concave mirror, further reflected by the uneven reflecting surface, and reflected again by the concave mirror, Irradiates cars, etc.

An on/off switch 11, a rotary switch 12, and a timer switch 13 that repeatedly turns on and off at a fixed time are connected in parallel between the cathode side of the DC power supply 10 and the cathode side of the DC power supply 10. Note that a mode selection switch 14 is also provided for controlling each of these switches.

When the on/off switch 11 is turned on by operating the mode selection switch 14, all the light emitting diodes 7 are turned on and are permanently lit. Also, while the on/off switch 11 is in the OFF state, the timer switch 13 is turned off.
When operated, all the light emitting diodes 7 repeatedly blink and turn into blinking lights. Further, when the rotary switch 12 is operated while the on/off switch 11 is kept in the off state, the light emitting diodes 7 repeat blinking one by one and become a rotating light.
