Description

[Detailed Description of the Invention] The present invention relates to a portable signal light that is equipped with a retroreflector around the outside of the signal light that flashes a white bulb via a switch.

In order to control traffic at night, it is desirable to make the signal lights that guide cars visible to drivers as soon as possible.

Therefore, in general, a red lens is placed around the tip of the signal light to emit red light to make it visible.
Alternatively, there is a similar device with a reflective tape wrapped around the bottom so that it can be seen by both irradiated and reflected light.

However, in the former, the irradiation surface is small, and in the latter, the irradiation surface is almost sufficient for both irradiation and reflected light, but in terms of reflection function, it is several minutes smaller than that of a right triangular pyramid. In addition, there are other drawbacks such as the tape peeling off during use, resulting in reduced functionality.

In view of this, the present proposal aims to provide a strong portable signal light with a large illumination surface, a higher reflector than conventional reflective tapes, and a stronger portable signal light.

To explain the embodiment in detail below with reference to the drawings, 1 is a cylindrical lamp body that contains a power source 2 such as a dry battery and a white bulb 3, and the white bulb 3 is a switch 4 equipped on the lamp body 1. It is designed to be able to blink.

A colored, for example, red irradiation lens 5 is attached to the tip of the lamp body 1 and covers the white bulb 3.

A reflector 6 made of synthetic resin such as acrylic resin is attached around the outside of the lamp body 1.
is equipped with a group of reflective elements in the form of an equilateral triangular pyramid on the back side.

When attaching this reflector to the lamp body, it is preferable to arrange a plurality of reflectors in succession in the circumferential direction of the lamp body 1 to form a polygonal surface as shown in the figure. In contrast, when the lamp body 1 has a polygonal surface, it exhibits a planar reflection pattern, which has the advantage of increasing the reflection effect. If you are using the above method, make several stages (three stages in the drawing).
By arranging the reflectors in different colors and using different colors of the reflectors for each stage, it is possible to create visibility due to different colored light rays upon reflection.

8 in the figure is a transparent lens 9 fixed to the tip of the irradiation lens 5
is a fixture for fixing the reflector 6.

When traffic control is performed at night in this manner, the light from the light source is irradiated to the outside through the irradiation lens 5, and the headlight beams projected onto each reflector are retroreflected and made visible to drivers and the like.

As mentioned above, since the crystal is equipped with a so-called prism-type reflector made of synthetic resin material on the outer circumference of the lamp body 1, it has a higher reflection efficiency than conventional reflective tape, and can easily distinguish between self-projected rays and reflected rays. Since the reflector is not visible to the driver, it has a high visibility effect, and since the reflector is made of synthetic resin, there is no risk of damage and it functions semi-permanently.

Note that the irradiation lens 5 may be a commonly used knurled lens, but if the reflector 6 described in this proposal is used, the irradiation lens will also have a reflection effect, increasing its light power. .
