PROBLEM TO BE SOLVED: To provide a lifesaving light to contribute to the discovery of a person who falls down in the water by automatic lighting when being put in the water. SOLUTION: A red luminous LED 4 and a power circuit 5 to light this LED 4 are built in an underwater lifesaving light main body 1. And a water sensor switch 6 is attached at the position that is in a part of the main body 1 and is submerged. When the device is prepared in that way described above, the water sensor switch is turned ON in the water and the LED 4 lights. Accordingly, a person who falls down in the water can be discovered quickly and can be saved.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an underwater life-saving light capable of detecting a fallen person immediately when a fisherman, a passenger or the like falls into the water and quickly rescuing the person.

[0002]

2. Description of the Related Art In the dark, when a fisherman falls into the sea or river at night, it may take time to find a faller and rescue may be delayed. Even in bright daylight, discovery can be similarly delayed if the water is dirty, sinks deep in the water, or is hidden behind rocks.

[0003]

As a result, a serious accident involving life and death may occur. Therefore, in the event of an accident, there is a need for a proposal of a life-saving light that can be used to detect a fallen person. I was

[0004] The present invention has been proposed in view of the above point, and an object of the present invention is to provide a life-saving lamp that automatically lights up when falling into water and contributes to finding a fallen person.

[0005]

According to a first aspect of the present invention, there is provided an underwater lifelamp, wherein a light emitter and a power supply circuit for lighting the light emitter are provided in a floating body. The power circuit of the light emitter is turned on and off at a position where the light emitter is submerged in a part of the main body.
A water sensor switch for F is attached.

Further, in the invention according to claim 2,
The invention according to claim 1 is characterized in that a day / night detection sensor is inserted in the power supply circuit, and the light emitter emits light when the water sensor switch is turned on when the day / night detection sensor is turned on. .

Further, in the invention according to claim 3,
In the invention according to claim 1 or 2, the light-emitting body is an LED.
Characterized by the following.

Further, in the invention according to claim 4,
The invention according to claim 1, 2 or 3, wherein a voice or signal transmission circuit is incorporated in the power supply circuit so as to notify the position of the fallen person by voice or signal in addition to light emission. is there.

[0009]

[Action] A life-saving light is tied to a part of the body or a piece of clothing using a string or the like, and acts so that it does not separate from the body when it falls. If it falls into the water, the water sensor switch is turned on, the power supply circuit of the light emitter is closed, and the light emitter emits light. As a result, the position of the fallen person can be immediately recognized, and rescue can be quickly performed. The luminous body may emit light regardless of day or night, but in order to emit light only at night, insert a day / night detection sensor in the power supply circuit and emit light only at night (constant darkness). You may.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block diagram showing an embodiment of the present invention; FIG. In FIG. 1, reference numeral 1 denotes a main body of an underwater life-saving light in which a lower portion 2 is made heavy and an upper portion 3 is formed light so as to stand upright in a floating shape in water.
The lower part 2 and the upper part 3 are openably and closably connected by screws, and the upper part 3 is formed of a transparent body, into which a red light emitting LED 4 is incorporated. The lower part 2 has the L
A power supply circuit (control circuit) 5 for causing the ED 4 to emit light is incorporated.
Is a part of the lower part 2 and is exposed at a position submerged in the water. When the electrodes 6a and 6b submerge in the water, electricity flows between the electrodes 6a and 6b due to the conductive action of water, and the power supply circuit 5 is closed. Is what it does.

Reference numeral 7 denotes a day / night detection sensor attached to a part of the main body 1. The day / night detection sensor 7 sends a signal to the power supply circuit 5 when the surroundings are at night or under a constant darkness due to underwater. When the water sensor switch 6 is ON, the LED 4 emits light. However, the day / night detection sensor 7 is not always necessary, and regardless of day / night, the LED 4
This is not necessary when emitting light.

In addition to the above embodiment, by incorporating a circuit for generating a sound or a signal when the power supply circuit 5 is closed, a person who has fallen underwater can be found not only by light but also by sound or instruments. You may comprise. Also, the LED 4 is a blinking type, and the color is advantageous because red is easy to find,
It may be a light bulb or the like.

[0013]

As described above, according to the present invention, a luminous body which emits light by a water sensor switch is incorporated in a float-shaped main body, and this luminous body emits light when a person falls into water.
The following effects are obtained. 1. When an angler falls into the sea or river, the position can be found immediately. 2. Because of the float shape, it does not sink in water, and the luminous body part floats on the water surface, so it is easy to notice and easy to find. Of course, since it emits light even in water, there is no problem even if it sinks with a fallen person. 3. In lifeboats, sightseeing boats, etc., handing out this life-saving light when boarding and returning it when disembarking is useful for life-saving activities in the event of an accident. 4. In addition, the present invention may be used not only for underwater life-saving lamps, but also for example, by incorporating an electrode part into a diaper for the elderly so that a third party can understand urination.
