Description

[Detailed description of the invention] (a) Industrial application field The present invention relates to a blinking display device that can arbitrarily change the radiation direction and color of light rays.

(b) Prior art There are various types of blinking display devices in which a reflecting mirror is fixed in the radiation path of the light beam from the rotating light and changes the direction of radiation of the light beam from the rotating light (for example, Jikkosho's
No. 59-1255, Jitko No. 59-4481, Jitko No. 57-
This is what is described in Publication No. 58648. ).

However, in both cases, the reflecting mirror is fixed to a base or the like, so it is not possible to arbitrarily select its mounting angle, etc.

Also, a marker light has been proposed in which a rotatable reflecting mirror is provided in front of a fixed sealed beam light bulb (see, for example, Japanese Patent Application Laid-Open No. 49-40699 and Publication of Utility Model Publication No. 56-61902).

However, the sealed beam light bulbs described in these publications are fixed and do not rotate. Therefore, the light is only emitted in a certain direction and does not blink.

On the other hand, since flashing display devices are installed in locations with various conditions such as construction sites and accident sites, it would be possible to adapt the radiation direction and color of the light beam to the specific conditions of the installation site. It's convenient.

For example, on straight roads such as expressways, it is necessary for light rays to reach as far as possible, but on roads with curves, such as mountain roads, if the light rays reach far away, the light rays will deviate from the road and cause light pollution. There is a risk that this will cause However, as mentioned above, conventional devices were not able to do this, and the display function was not fully demonstrated.

(C) Purpose of the invention The present invention has been made in view of the drawbacks of the above-mentioned prior art, and includes a rotatable light control plate provided in the radiation path of the light beam from the rotating lamp.
The present invention aims to realize a flashing display device that can be used at a construction site or the like to select the light emission conditions that suit the site.

(d) Structure of the invention The invention is based on a rotating light whose radiation direction of light rays rotates, a holder for the rotating light, and a symmetrical position on the radiation path of the light around the rotating light. At least two light beam controllers are provided, each having a rotational axis substantially parallel to the rotational axis of the rotating light near one side edge, and which is rotatable about the rotational axis and provided on the holding base. It is a flashing display device consisting of a plate, and by rotating the light beam control plate, the direction and color of the light beam from the rotating light can be arbitrarily controlled.
