Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention mainly relates to a lifesaving light emitting device which is provided as a fitting in a life jacket or a lifeboat for marine accidents and which emits a flash for notifying a searcher of a position in case of a disaster.

[0002]

2. Description of the Related Art Conventionally, as shown in FIG. 4, a light emitting device of this type has been developed in which a light transmitting portion 2 is provided on the top of a casing 1 and a rod-shaped light emitting tube 3 is installed in the light transmitting portion. The electric current is intermittently supplied by the electronic circuit and the battery provided in the casing 1 so that the arc tube 3 emits a flash of light.

The arc tube 3 is used to emit light by applying a high voltage between the electrodes at both ends to discharge the voltage. The arc tube is charged with a voltage charged in a capacitor by a booster provided in an electronic circuit. 3 is applied to both electrodes, and another high voltage is instantaneously applied to the trigger electrode of the arc tube 3 so that a strong flash light is emitted.

[0004]

In the conventional life-saving light emitting device as described above, since the light emitting tube is installed horizontally in the light transmitting portion, the axial direction of both ends of the light emitting tube is shaded by the electrodes. However, there is a problem that the farther away the shadow is, the larger the area that the light cannot reach becomes.

In view of the above conventional problems, the present invention has been made for the purpose of providing a life-saving light-emitting device which emits light in the entire 360 ° range in the horizontal direction and in all directions above the hemisphere.

[0006]

The features of the present invention for solving the above-mentioned conventional problems and achieving the intended purpose are as follows.
The casing has a casing having a translucent portion, and the casing is provided with an elongated arc tube, and an electronic circuit and a battery for intermittently supplying a current to the arc tube are housed in the casing. In the life-saving light emitting device, a bottom wall of the translucent portion is provided with a partition wall that partitions the interior of the casing below the light transmissive portion, and a light reflecting plate is installed upward on the upper surface of the partition wall and above the reflecting plate. The arc tube is installed in an obliquely raised position.

[0007]

In the lifesaving light emitting device of the present invention, since the light emitting tube is arranged obliquely upright, it is 360 ° in the horizontal direction.
There is nothing other than the conductive wire that blocks light in the range of, and since it can be made sufficiently thin compared to the arc tube, light is emitted in all horizontal directions.

On the other hand, the extension direction of the upper end side of the arc tube is shaded due to the electrode, but the light reflected from the reflection plate reaches that direction, and the light is emitted in all hemispherical directions. Becomes

EXAMPLE An example of the present invention will be described with reference to FIGS.

In the figure, 11a is a bottomed cylindrical casing body, 11b is a lid body which is watertightly closed at the opening of the casing body 11a, and the casing is constituted by the body 11a and the lid body 11b. are doing.

The lid 11b is formed of a transparent material, has a hollow hemispherical portion 12 formed on the top, a male screw 13 is formed on the outer periphery of the lower end, and a flange 14 is integrally formed on the upper side thereof. The male screw 13 is screwed into a female screw on the inner peripheral surface of the opening of the casing body 11a, and an O-ring 15 for stopping water is interposed between the flange 14 and the upper surface of the body to maintain watertightness.

A partition plate 16 is fitted in the lower end of the lid 11b, and a reflection plate 17 is fixed on the partition plate 16. An arc tube 17 is installed above the reflection plate 17 while being supported by the partition plate 16.

The arc tube 18 is an elongated hollow glass tube in which discharge electrodes 18a, 18c and a trigger electrode 18b are enclosed at both ends. A booster provided in an electronic circuit charges a capacitor and a voltage is applied to both discharge electrodes. 18a, 18c
By applying another high voltage to the trigger electrode 18b for a short time, a strong flash light is emitted.

Then, a hard wire is used for one of the conducting wires 19 for supplying a current to the arc tube 18, and this is made into a gate shape to stand up on the partition plate 16, and one electrode 18a is soldered to this. By soldering the other electrodes 18b and 18c to the other conductor wire 20 near the surface of the partition plate 16, the arc tube 18 is fixed in a state in which it is raised obliquely upward at an angle of approximately 45 °.

An electronic circuit box 21 is housed in the casing body 11a, and a switch 22 is provided above the electronic circuit box 21. As shown in FIG. 3, the switch 22 includes an insulating plate 2 between a pair of contact spring pieces 22a and 22b.
3 is inserted and configured. The insulating plate 23 is integrally formed with the body of the casing main body 11a at the tip of the operation rod 24 that penetrates the peripheral wall and projects outward. In the figure, 25 is a packing for stopping water.

Then, by pulling the pulling string 26 having one end fixed to the operating rod 24 and pulling out the insulating plate 23 at the tip of the operating rod 24, both contact spring pieces 22a and 22b elastically contact each other, and the switch 22 operates. It is supposed to be turned on.

In the figure, 27 is a battery for power supply, 28 is a capacitor, and switch 21 is O.
As a result, the battery 27 is used as a power source, the current charged in the capacitor 28 is intermittently discharged, the voltage is boosted and supplied to the arc tube 17, and the flash light is intermittently emitted.

[0018]

As described above, in the lifesaving light emitting device of the present invention, the reflecting plate is placed at the bottom in the light transmitting part of the casing, and the arc tube is installed so as to be obliquely raised above the reflecting plate, so that the horizontal direction is achieved. The only thing that blocks the light of is a thin conducting wire, and light will be emitted in the entire circumferential direction,
Not only is the light emitted directly from the launch tube upward, but the light reflected by the reflector is also emitted, so the light reflected by the reflector in the direction along the central axis of the arc tube where the direct light is blocked is also emitted. Is emitted, light is emitted in all directions of the hemisphere, and the blind spot where the light is blocked has completely disappeared.
