DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diffused warning light which is mounted on a roof of a vehicle and emits a rotating flash or a siren as a warning signal and is used for alerting or guiding pedestrians. Things.

[0002]

2. Description of the Related Art A conventional diffused warning light emits a rotating flash and a reflected light over the entire circumference. Among them, various types have been proposed that feature strong light emission in the forward, rearward, front-rearward, or oblique directions.

[0003] However, depending on the use of the diffused warning light, there is a case where emission of strong warning light is unnecessary or emission of weak warning light is desired. For example, the situation of an emergency vehicle equipped with a diffused warning light may be during driving in a residential area at midnight or when stopping after arriving at the accident site. In particular, there is a glare to the driver of the vehicle traveling from behind the emergency vehicle, maintaining the warning light by the strong emission of the diffused warning light and the anti-glare to the rear has not been resolved on driving safety. It was an inevitable task.

[0004] As a means for solving the above-mentioned problem, the applicant has previously filed a utility model application published in 1991 in Japanese Patent Application No. 50705.
As shown in the figure above, it has translucency in the direction opposite to the direction of travel of the vehicle with diffused warning light, locks the anti-glare filter with predetermined light transmittance, and forms an anti-glare structure behind the mounted vehicle Means have been proposed to do so.

Similarly, Japanese Utility Model Publication No. 1320
No. 04, a filter with a filter for dimming or dimming the irradiation light in a predetermined direction, or a light shielding plate or a dimming plate behind a rotating lamp, as in Utility Model Application Publication No. 21448, 1983. Some are detachably mounted.

[0009] As shown in FIG. 9, paint or the like is applied to the inner surface or the outer surface of the rear side of the globe 91 of the diffused warning light 92, and the emission behind the rotating light 93 is blocked. There were diffused warning lights with an anti-glare structure.

[0007]

However, in a structure in which a filter, a light-shielding plate, or a dimming plate is attached to a diffused warning light as in the former conventional example, there is an anti-glare effect on the rear side, but the light amount on the front side is not at all. There were drawbacks that were not taken into account.

In the case of the structure in which the glove is painted as in the latter conventional example, no consideration is given to the amount of light to the front as in the former conventional example. Further, in this structure, it is necessary to dry the coating after the coating, so that unevenness may occur between a dark portion and a light portion. Further, there is a disadvantage that the coating may come off with the passage of time. According to the conventional anti-glare structure,
Rotational emission and reflection emission to other than
Because it is blocked, lighting can be confirmed around 150 m
Difficult warning lights for road maintenance work vehicles, etc.
Had the disadvantage that it could not be used.

[0009]
