Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a diffusive warning light mounted on a roof of a vehicle and used as a warning signal to emit a rotating flash, a siren sound or the like for the purpose of alerting or guiding a passerby. It is a thing.

[0002]

2. Description of the Related Art A conventional diffusing type warning light emits a rotating flash light and a reflected light projection all around the circumference. Among them, various proposals have been made that are characterized by strong emission in the front, rear, front and rear, or oblique directions.

However, depending on the usage of the diffused type warning light, there are cases where strong emission of warning light is unnecessary or weak emission of warning light is desired. For example, the situation of an emergency vehicle equipped with a diffused warning light is, for example, during traveling in a residential area at midnight or when the vehicle is stopped after arriving at the accident site. In particular, there is a dazzling effect on the driver of a vehicle traveling from the rear of an emergency vehicle, and the warning light due to the powerful emission of the diffuser type warning light is maintained and the antiglare to the rear is not a solution for driving safety. It was a problem that must not be met.

[0004] Therefore, as a means for solving the above problems, the applicant has previously filed a utility model application publication No. 50705 in 1991.
As shown in No. 5, the vehicle has a light-transmitting property in the direction opposite to the traveling direction of a vehicle equipped with a diffuser type warning light, and an anti-glare filter with a predetermined light transmittance is locked to form an anti-glare structure behind the vehicle. Means have been proposed.

[0005] Similarly, 1991 Utility Model Publication No. 1320
No. 04, which has a filter for dimming or dimming the irradiation light in a predetermined direction, or a light-shielding plate or dimming plate behind the rotating lamp, as in Utility Model Application Publication No. 21448 of 1983. There is something that can be attached and removed freely.

In addition, as shown in FIG. 9, paint or the like is applied to the inner or outer surface of the rear side of the globe 91 of the diffuser type warning light to make it 92, thereby blocking the rearward light emission of the rotating light 93. There were diffused type warning lights with an anti-glare structure.

[0007]

However, in the structure in which a filter, a light-shielding plate or a dimming plate is attached to the diffuser type warning light as in the former conventional example, there is an antiglare effect on the rear side, but there is no light quantity on the front side. There were drawbacks that were not considered.

As with the former conventional example, no consideration has been given to the amount of light to the front of the structure of the latter conventional example in which the gloves are painted. Further, in this structure, since it is necessary to dry the coating after coating, unevenness may occur between a dark portion and a thin portion. Further, there is a drawback that the coating may peel off with the passage of time.

[0009]

SUMMARY OF THE INVENTION Therefore, the present invention is to solve the above-mentioned problems, and the rotation emission of the rotating lamp and the reflection of the reflecting plate are provided between the rotating lamp and the globe. An anti-glare reflector is provided which blocks the emitted light in a predetermined direction and reflects the light in the opposite direction. With the above-described configuration, the rotation light emission of the rotating lamp and the reflection light emission of the reflector are shielded in a predetermined direction in which antiglare is desired, and are reflected in the opposite direction.

According to a second aspect of the present invention, there is provided a diffuser type warning light in which the anti-glare reflector is appropriately engaged with a spacer panel from the side of the glove so that the anti-glare reflector is locked to ribs provided above and below the inner surface of the glove. The feature is that they are inserted and arranged in combination. With the above configuration, it becomes possible to easily attach the antiglare reflector to the diffuser type warning light,
The rotating light emitted from the rotating lamp and the reflected light emitted from the reflector are partially blocked in a predetermined direction in which antiglare is desired, and are reflected in the opposite direction to the predetermined direction.

According to a third aspect of the present invention, there is provided a diffusing type of warning light in which the anti-glare reflector is provided with a mirror-finished reflecting surface and has a large number of openings having a predetermined aperture ratio. To do. With the above configuration, the rotary light emitted from the rotating lamp and the reflected light emitted from the reflector are partially blocked in a predetermined direction in which antiglare is desired, and reflected in the opposite direction.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention will be described below with reference to the drawings. FIG. 1, FIG. 2, and FIG. 3 are a front view, a plan view, and a side view showing the entire diffuser type warning light.

Reference numeral 1 denotes a base having a horizontally long plate shape,
Each component is placed on the base, which is usually formed by aluminum extrusion. Reference numeral 2 is a glove, which is mounted on the base 1 to cover the respective constituent elements and to project warning light in a colored manner. It has an elliptic cylindrical shape with a lower surface cut out and is made of a translucent material. The optical element parts are covered from both sides of the base 1.

Reference numeral 3 denotes a revolving light, and the light source 3 of the revolving light 3
1. A reflector 32 for reflecting and emitting the rotating light emitted from the rotating lamp 3 to the surroundings and a rotating mechanism (not shown). 4 is an antiglare reflector. A transparent acrylic plate having a horizontally long rectangular shape and usually formed by vacuum vapor deposition is used, but another forming method may be used as long as it can provide a mirror surface that reflects light. It is installed in the longitudinal direction of the diffused warning light.

The positional relationship between the rotating lamp 3 and the antiglare reflection plate 4 is as follows. That is, a plurality of rotating lights 3, 3 are arranged on the center line in the longitudinal direction of the diffuser type warning light. Reflecting plates 32, 32, ─ are arranged between the rotating lights 3, 3, ─ in a "V" shape or an inverted "U" shape so that the rotating lights 3, 3, ─ rotate and emit light. It reflects and emits light to the surroundings. Anti-glare reflection plates 4, 4, ... are appropriately arranged in front of or behind the rotating lights 3, 3 ,.

Reference numeral 5 is a bracket for mounting the diffused warning light on the vehicle. Three pieces are provided on the lower surface of the base 1 and fixed to the vehicle.

A light diffusing type warning light is constructed by the above respective components, and an optical machine in which a base, which is a support body, a rotating light on the base, and a reflecting plate are covered with a globe, is roughly provided. It is composed of a combination of element parts.

Next, FIG. 4 shows a mounting state of the antiglare reflection plate 4 according to the present invention. Although the angle 41 is fixed to the rear part of the base 1 by the screw 43 in the forward direction, and the antiglare reflection plate 4 is swaged at two places by the rivets 42 and attached to the L-shaped long part of the angle, the other method is shown. It depends on the method.

Further, FIG. 5 shows a path diagram of the warning light according to the present invention. Ray a emitted backward from the rotating light 3
Is reflected by the anti-glare reflection plate 4 to become a light beam b and returns back to the light source portion of the rotating lamp 3. Therefore, the light beam c emitted to the front overlaps with the light beam c to block the light to the rear and increase the amount of light to the front. . Regarding the rate of increase in the amount of light, the diffused warning light with the anti-glare reflector 4 installed and the diffused warning light without the anti-glare reflector 4 operated for a certain period of time in a dark room Was measured and the calculated amounts of light were compared, and the rate of increase was about 30%.

The above description is based on the assumption that the diffused warning light is mounted on the roof of the vehicle and used to increase the amount of light in the forward direction.

In addition, as shown in FIG. 6, by using the diffuser type warning light according to the present invention installed rearward at the rear of a vehicle such as an accident handling vehicle or a road construction vehicle, the amount of light emitted to the rear can be increased. Can be used to prevent accidents such as a rear-end collision of a succeeding vehicle especially in bad weather such as fog or snowstorm. In this case, there is also an advantage that the driver does not see the flash of the rotating lamp directly or indirectly through a rearview mirror or the like, so that the driver is not dazzled.

With the above structure, an antiglare structure for a diffused type warning light is provided. Here, the diffused type warning light has a structure of a combination of rotating lights, but it is more preferable to adopt a rotating light having a rotation stop and blinking function. The present invention can be used not only in the diffused warning light shown in the embodiment but also in other diffused warning lights such as those with a speaker and general rotating lights.

FIG. 7 shows an antiglare reflector 4 showing a second embodiment.

21 are provided so as to oppose the upper and lower sides of the inner surface of the globe 2, and the antiglare reflection plates 44, 44 and the spacer panels 45, 45 are inserted and arranged from the side surface side of the globe 2 in an appropriate combination.

As described above, the mounting of the antiglare reflectors 44, 44 becomes easier and the spacer panels 45, 45 are provided.
Has a predetermined light emission rate, so that it is possible to obtain an effect that the rotation light emission and the reflection light emission are reflected in the opposite direction to the predetermined direction without being completely blocked while maintaining the antiglare effect in the predetermined direction. It is necessary for the diffused warning light installed on the vehicle for road maintenance work vehicle to be able to confirm the lighting from a distance of 150m around (this is because the safety standard for road transport vehicles is Article 49-2). In addition, it is effective to have a structure in which the anti-glare effect is maintained in a predetermined direction while not completely blocking.

FIG. 8 is a front view of an antiglare reflection plate showing a third embodiment. It has a mirror-finished anti-slope 46 and has a large number of openings 47, 47, ... With a predetermined aperture ratio. As the openings 47, 47 having a predetermined aperture ratio, FIG.
There are slits shown in FIG. 8A and small holes shown in FIG. 8B, but the slits are not limited to these.

The aperture ratio is preferably around 10% to 40% in the case of the embodiment shown in FIG. 6, and around 40% to 70% in the case of normal use in other vehicles. In any case, since it is possible to provide a dazzling reflector having a desired aperture ratio according to the intended use, it is possible to obtain antiglare according to the usage situation.

Apertures 47, 47 having such a predetermined aperture ratio,
Since it has a large number of-, it is possible to obtain an effect that the rotation light emission and the reflection light emission are reflected in the opposite direction to the predetermined direction without being completely blocked while maintaining the antiglare effect in the predetermined direction. Therefore, it is also effective for a diffused type warning light mounted on the vehicle for a road maintenance work vehicle.
