Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a rotation warning light mounted on an emergency vehicle such as a patrol car, an ambulance or a road work vehicle.

[0002]

2. Description of the Related Art A rotating warning light is mounted on a roof of an emergency vehicle such as a patrol car or a road work vehicle, and circulates a diffused signal to the surroundings to warn other vehicles or pedestrians. .

As such a rotation warning light, for example,
There is a structure shown in FIG. This rotation warning light is a rotation light (2) arranged near the center of a substantially disk-shaped base (1).
Is covered with a transparent globe (3) colored in red, blue, yellow or the like. Here, the revolving light (2)
Is a structure in which a halogen lamp (2b) and the like are arranged at the focal position of a reflecting tube (2a) having a symmetrical shape such as joining two bowl-shaped bodies, and is arranged in the table (1). It is rotated by a driving motor (not shown) that has been driven, and collects the irradiation light of the lamp (2b) on both left and right sides to irradiate a directional light flux in a horizontal direction around the device stand (1).

In addition to this, as a rotation warning light, as shown in FIG.
There is also a so-called diffusing type warning light having a structure as shown in (b).

This rotation warning lamp has a substantially rectangular base (1).
A rotating lamp (2) having the same structure as described above is arranged on both sides of the speaker, and a plurality of reflectors (5) are provided between the rotating lamp (2) and the speaker (4) arranged in the center. The rotary lamp (2) and the reflector (5) are arranged and covered with a translucent globe (3).

As shown in FIG. 5A, when the rotating lamp (2) rotates and reaches the position of the broken line in the figure, the irradiation light emitted from the rotating lamp (2) is on both sides of the rotating lamp (2). The illuminating light radiated toward one side and the inside of which is radiated, is reflected by the reflection plate (5).
The light is reflected forward (downward in the figure a) and backward. Therefore,
In this type of revolving warning light, it is installed on both sides of the stand (1).
Direct light from the revolving light (2) illuminates the front and rear
Direct light from the rotating lamp (2) and reflection from the reflector (5)
Both of the light are emitted.

[0007]

By the way, FIG. 5 (a)
In the rotation warning lamp shown in (b), since the irradiation light of the rotating lamp (2) is irradiated in the horizontal direction, in order to effectively reflect the irradiation light by the reflector (5), The revolving light (2) must be installed at the same height. Therefore, the shape of the rotation warning light is limited to a linear shape parallel to a horizontal plane, and it has been extremely difficult to provide warning lights of various forms. Further, since the direct light and the reflected light are irradiated at the same height, the irradiation range of the irradiation light is narrow especially in the vertical direction, and the visibility from above and below is deteriorated. So, for example, large
If you install this rotation warning light on the roof of
In the case of other vehicles, other vehicles running on the side road or pedestrians work
There were problems such as not being able to recognize the approach of a car.

In view of the above problems, it is an object of the present invention to provide a rotation warning lamp which can secure a wide irradiation range of irradiation light in the vertical direction and can freely select various forms. .

[0009]

In order to achieve the above-mentioned object, the present invention provides a rotating lamp for irradiating irradiation light in a horizontal direction while rotating on a base, and an irradiation light irradiated from the rotating light. In a rotation warning light comprising a reflecting plate reflecting in a predetermined direction, the rotating lamp and the reflecting plate covered with a translucent globe,

A refracting body for refracting the irradiation light emitted from the rotating lamp upward or downward is disposed between the rotating lamp and the reflecting plate, and the reflecting plate refracts the irradiation light refracted by the refracting body effectively. It was decided to place it above or below the revolving light so that it would be possible.

[0011]

The refractor disposed between the rotating lamp and the reflecting plate refracts the irradiation light emitted from the rotating lamp upward or downward. Therefore, the reflecting plate is arranged so that the refracted irradiation light can be effectively reflected. When it is arranged above or below, the positional relationship between the rotating lamp and the reflector plate is inclined. Here, since the positional relationship between the rotating body and the reflector can be freely changed by appropriately changing the refractive index of the refraction lens, the form of the rotation warning lamp can be freely selected. Moreover, since the irradiation heights of the direct light emitted from the rotating lamp and the reflected light reflected by the reflecting plate are different, the irradiation range of the irradiation light can be widened in the vertical direction.

[0012]

Embodiments of the present invention will be described below with reference to FIGS. In this embodiment, the same members as the conventional members are designated by the same reference numerals and the description thereof will be omitted.

FIG. 1 is a so-called diffusing warning light, and includes a base (1), a rotating light (2) disposed at both ends of the base (1), and a rotating light (2). Between the speaker (4)
The refracting body (13) and the reflector (5), which are sequentially arranged from the side of the rotating lamp (2), are used as main components, and the rotating lamp (2), the reflector (5) and the refracting body (13) are transmitted. It is constructed by covering with a glove (3). The revolving light (2) connects two bowl-shaped bodies.
Focus position of the reflector (2a) with symmetrical shape
Is equipped with a halogen lamp (2b), etc.
(1) Drive motor (not shown) placed inside
It is rotationally driven.

The refraction body (13) is made of a translucent material such as glass, and has a sawtooth shape in which a plurality of members having a wedge-shaped cross-section that expand in diameter upward are connected. This refractor (1
3) Keeping the same height as the revolving light (2), the base (1)
By mounting it on the top, the irradiation light is refracted upward when passing through the refraction body (13). On the other hand, the reflector (5) is formed in a mountain shape by joining or bending, and is mounted on the base (1) with its top facing the rotating lamp (2). At this time, the reflection plate (5) is arranged at a position higher than the rotating lamp (2) so that the irradiation light refracted upward by the refraction body (13) is surely applied to the reflection surface.

As described above, in the present invention, the refracting body (13) is arranged between the rotating lamp (2) and the reflecting plate (5), and the irradiation light emitted by the rotating lamp (2) is refracted upward. Therefore, the reflection plate (5) can be arranged above the rotating lamp (2). Therefore, the instrument base (1) can be formed into a trapezoidal shape as shown in the drawing, and it becomes possible to provide a rotation warning lamp having a shape that has not existed in the past. Also, refractor (1

The positional relationship between the reflector and the reflector (5) can be freely changed, whereby the form of the rotation warning light can be freely selected.

By the way, as the illumination light irradiated to the front and rear vessels stand (1), and the light directly emitted directly from the rotating lamp (2), 2 of the reflected beam irradiated by the reflector (5) According to the present invention, there are different types, but since the arrangement heights of the rotating lamp (2) and the reflector (5) are different, the irradiation heights of the above-mentioned two kinds of irradiation light are different. Therefore, it is possible to irradiate the irradiation light in a wider range in the up and down direction, which also improves the visibility from the front or the rear.

Further, as shown in FIG. 5, the refracting body (13) may have a shape in which a plurality of members each having a wedge-shaped cross section which expands downward are connected (reference numeral (13 ')). As a result, the irradiation light is refracted downward when passing through the refraction body (13 '), so that the reflection plate (5) is arranged below the rotating lamp (2) so that the refraction light is surely irradiated. As a result, it becomes possible to manufacture a rotation warning lamp having a shape as illustrated. Also in this case, the irradiation range of the irradiation light can be widened in the vertical direction similarly to the above.

The present invention is based on the above-described instrument base (1).
Not only a rotation warning light of the type having a speaker (4) in the center of the and a rotating light (2) and a reflector (5) at both ends thereof, at least the rotating light (2) and the reflector (5). )
It is applicable to all types of rotation warning lights equipped with. Further, the shape of the refraction body (13) is not limited to the shape shown in FIGS. 4 and 5, and as shown in FIG. 6, the same effect can be obtained even if it has a wedge-shaped cross section that expands upward or downward. It can be obtained (the drawing shows the case where the diameter is increased upward).

[0019]

According to the rotation warning light according to the present invention, it is possible to arrange a reflector above or below the position of the rotating lamp, these positional relationships are to change the refractive index of the refractive member appropriately Can be freely selected. Therefore, the form of the rotation warning light can be freely selected, and it is possible to provide the rotation warning light having various forms according to the needs of the user.
Further, since the irradiating heights of the irradiating light by the rotating lamp and the reflecting plate are different from each other, the irradiating range of the irradiating light becomes wide especially in the vertical direction, and as a result, visibility from the surroundings can be improved.
