Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an emergency light mounted on a vehicle or the like, and more particularly to an emergency light for notifying a following vehicle or a road office of information such as an accident or a failure.

[0002]

2. Description of the Related Art At present, vehicles such as passenger cars are obliged to equip a smoke tube as an emergency light for notifying other vehicles of an accident or a failure.

[0003]

However, this smoke tube has the following problems.

(1) Since the explosive is ignited to emit smoke, if gasoline leaks in the event of an accident, there is a risk that the fire of the smoke igniter will ignite the gasoline and cause a fire.

(2) Since the smoke generation time is as short as about 5 minutes, the smoke generation cylinder may disappear before the emergency vehicle arrives, which may delay the discovery of the accident site.

(3) It is necessary to install a new smoke tube after use because it cannot be used again once used, but it is difficult to understand how to purchase the smoke tube, and the smoke tube is left unmounted on the vehicle. Often.

(4) Ignition may become difficult in places with severe wind and rain, and it may become unusable.

(5) If it is used in a large amount in a tunnel, the visibility deteriorates and the emergency light cannot be seen, which may cause a secondary disaster. Also, its use in tunnels is limited due to air pollution.

(6) Due to the heat generated by the combustion of the explosive, the temperature becomes high, and it is difficult to hold it by hand and use it. There is also the risk of burns from flames and heat.

(7) Many people do not know how to use the smoke tube, and it may not be possible to actually utilize it in the event of an accident or breakdown.

Further, even if a trouble such as a flat tire, an engine stall, or a fuel exhaustion occurs on a general road, the trouble is only the problem of the broken vehicle. However, on the highway, these troubles are Since it may cause a serious accident involving the vehicle, it is necessary to notify the following vehicle as soon as possible and contact the road management office by emergency telephone.

Even when the emergency call is made, the emergency calls are provided at intervals of 1 km, but it is not known which direction from the current position to reach the nearest emergency call. In the worst case, the user must walk 900 meters or more, which is dangerous and time consuming.

Therefore, an object of the present invention is to provide a new emergency light which solves various problems of a smoke producing tube. Another object of the present invention is to provide an emergency light capable of immediately reporting the occurrence of a failure or accident.

[0014]

In order to achieve the above-mentioned object, the present invention uses a light emitting element, a blinking control unit for controlling blinking of the light emitting element, and an emergency telephone post provided along a road. A wireless telephone unit capable of communicating with a road management office, a radio unit capable of receiving roadside broadcasting or highway radio broadcasting, a battery, and the operating voltage from the battery, the blinking control unit, the wireless telephone unit, or the A selection switch selectively supplied to the radio unit is housed in the same housing.

[0015]

In normal times, by operating the radio section, it is possible to receive roadside broadcasting or highway radio broadcasting and obtain information useful for driving.

When a breakdown or an accident occurs, the wireless telephone unit is operated to enable communication with the road management office through an emergency telephone post provided along the road, and the failure or the accident is reported. It is possible to contact the details.

After the contact, by operating the blinking control section, the light emitting element starts blinking, and the following vehicle can be alerted.
