Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a life-saving light-emitting device, and more particularly, to a life-saving light-emitting device that facilitates finding a victim at night when an accident or disaster occurs.
[0002]
[Prior art]
For example, when a ship sinks and a drowning accident occurs, passengers, passengers, and other victims may wear life jackets and evacuate to a lifeboat. In the worst case, the victims will drift with their life jackets or with their floats waiting for the rescue team to arrive.
[0003]
However, if a water accident occurs during the day, distresses who have been evacuated to lifeboats or drifted are relatively easy to find, but if this occurs at night, It will be quite difficult. For this reason, in such an accident, the rescuer is notified of the position of the distress by using a smoke tube or a rescue signal lamp. However, distress notifications using such smoke cylinders and rescue signal lights are effective when rescue teams are nearby, but they do not withstand long-term use. There is a problem that the notification effect cannot be exerted when it is swept away from the point where it occurred.
[0004]
For this reason, for example, as described in Japanese Patent Application Laid-Open No. 2000-62687, a high-brightness LED and a buoyancy generation unit that floats the light-emitting unit of the high-brightness LED on the water surface are provided. A life-saving light-emitting device in which a light-emitting portion of a high-brightness LED protrudes from the top surface has been proposed. According to this life-saving light-emitting device, the light-emitting part of the high-intensity LED protruding from the top surface of the buoyancy generating part floats on the water surface and emits light. By holding the light emitting device, you can inform the rescue team where you are.
[0005]
[Problems to be solved by the invention]
However, the life-saving light-emitting device described in Japanese Patent Laid-Open No. 2000-62687 has the following problems.
(1) Since a primary battery, that is, a 3V dry battery is used as a power source for the light emitting part of the high-intensity LED of the life-saving light-emitting device, the battery does not emit light when the battery is exhausted. When the time is prolonged, there is a problem that nighttime light emission stops.
(2) For this reason, secondary batteries that can be recharged and used even when the batteries are exhausted, such as lead acid batteries, nickel-cadmium batteries, lithium ion batteries, etc., may be used as these power sources. In the case of a secondary battery, it is necessary to secure voltage and current to continuously cause a chemical reaction because it stores electricity by the movement of electrons (oxidation-reduction reaction) accompanying a chemical reaction. In situations where this is not possible. In response to this, for example, the electricity generated by the solar battery may be stored in the secondary battery to emit light, but in the case of the secondary battery, an unstable state where the solar battery voltage is close to 0V. In the case of cloudy or rainy weather, the current and voltage sufficient to cause a chemical reaction cannot be ensured, and power storage is not easy. For this reason, there is a problem that the power storage is insufficient, the light does not emit at night, and the functions sufficient for the discovery and rescue of the victim cannot be performed.
[0006]
Therefore, an object of the present invention is to provide a life-saving light-emitting device that can continue to emit light at night from the night when an accident occurs regardless of the weather, and can exert a great effect on the discovery and rescue of a victim. It is to provide.
[0007]
[Means for Solving the Problems]
The present invention, in order to achieve the above object, the life-saving light-emitting device including a power supply means for causing the LED to emit light and the LED, the upper Symbol supply means, all-weather that can be used as a rechargeable power supply during all weather The all-weather power supply means includes a solar battery, a charging voltage control means connected to the solar battery via a backflow prevention diode, and a charging voltage. An electric double layer capacitor connected to the control means for storing solar voltage, an illuminance switch connected to the electric double layer capacitor, and a battery voltage stored in the electric double layer capacitor switched and supplied by the illuminance switch to cause the LED to emit light And a constant voltage control circuit that controls the voltage so as to become a constant voltage, and the illuminance switch monitors the illuminance outside the life-saving light emitting device. Performs switching for supplying the battery voltage stored in the power electric double layer capacitor to the LED when a luminance or less, characterized in that for emitting the LED.
[0008]
In the above configuration, it is desirable that the primary power source means is composed of a dry battery and a switch for energizing the LED .
[0010]
According to the present invention, when a distress accident or the like occurs, the primary power source means is used for light emission of the LED at the night of the accident occurrence, and the light stored by the all-weather power storage means is used for light emission of the LED at night after that day. used.
[0011]
DETAILED DESCRIPTION OF THE INVENTION
Hereinafter, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
FIG. 1 is a view showing a life-saving light emitting device according to an embodiment of the present invention, FIG. 1 (a) is an external view thereof, and FIG. 1 (b) is an internal structural view thereof. As shown in FIG. 1 (a), the life-saving light emitting device 1 has a cylindrical shape, and as shown in FIG. 1 (b), a power source unit 10 and a light emitting unit 20 are integrated. It is.
[0012]
In this configuration, the power supply unit 10 contains a dry battery 11 that is a primary battery, an electric double layer capacitor 12 that can be rapidly charged, and an electronic circuit board 13 on which these are mounted. The LED 21 that emits light by the electric power of the dry cell 11 and the electric double layer capacitor 12 and the solar cell 22 that receives sunlight and supplies the battery voltage to the electric double layer capacitor 12 are housed.
[0013]
FIG. 2 is a diagram showing a circuit configuration of the life-saving light emitting device 1. As shown in the figure, it is composed of an all-weather power supply system side circuit 100 and a primary battery side circuit 200. The all-weather power supply system side circuit 100 includes a solar cell 11, an electric double layer capacitor 12, a charging voltage control circuit 110 that controls the charging voltage of the solar cell 22 supplied to the electric double layer capacitor 12, and the illuminance outside the apparatus. The illuminance switch 120 that performs switching to supply the battery voltage stored in the electric double layer capacitor 12 to the LED 21 when the illuminance is less than or equal to a predetermined illuminance is switched from the electric double layer capacitor 12 by the illuminance switch 120. And a constant voltage control circuit 130 that controls the battery voltage to be a constant voltage for causing the LED 21 to emit light. In addition, a backflow prevention diode 140 for preventing a backflow of the battery voltage of the electric double layer capacitor 12 due to the switching operation of the illuminance switch 120 is provided in the previous stage of the charging voltage control circuit 110.
[0014]
With this configuration, the battery voltage supplied from the solar battery 22 is controlled by the charging voltage control circuit 110, supplied to the electric double layer capacitor 12, and stored in the electric double layer capacitor 12. The illuminance switch 120 monitors the illuminance outside the apparatus, and performs switching to supply the battery voltage stored in the electric double layer capacitor 12 to the LED 21 when the illuminance is lower than a predetermined illuminance. The battery voltage switched and supplied from the electric double layer capacitor 12 by the illuminance switch 120 is controlled by the constant voltage control circuit 130 so as to be a constant voltage for causing the LED 21 to emit light.
[0015]
On the other hand, the primary battery side circuit 200 includes the above-described dry battery 11 and the battery side switch 210 that turns ON / OFF the power supply to the LED 21 by the dry battery.
[0016]
A method of using the life-saving light-emitting device 1 according to the present embodiment having the above configuration will be described. First, since the dry battery 11 as a primary battery cannot be charged when the battery is exhausted, for example, when a distress accident occurs, it is used at least for light emission of the LED 21 at the night of the accident occurrence. On the next day, electricity generated by the solar cell 22 by daytime sunlight of the day is stored in the electric double layer capacitor 12, and the electric power stored in the electric double layer capacitor 12 is used for light emission of the LED 21 at night after that day. . Thereby, LED21 can be light-emitted at night continuously from the night when an accident generate | occur | produces.
[0017]
In the present embodiment, the electric double layer capacitor 12 is used as the power storage means for the following reason. That is, the electric double layer capacitor is smaller in terms of electric capacity than a secondary battery such as a lithium ion battery, but can be rapidly charged (approximately several seconds). In the case of a secondary battery, it is necessary to secure voltage and current to continuously cause a chemical reaction because it stores electricity by the movement of electrons (oxidation-reduction reaction) accompanying a chemical reaction. In this case, charges are accumulated without moving electrons due to a chemical reaction, and the terminal voltage rises according to the amount of charge current. Since the voltage is 0 V in the case of complete discharge, the charging mode is entered if a voltage is applied or there is a current amount. For example, the difference in charging characteristics between a secondary battery and an electric double layer capacitor when a solar battery is taken as an example can be said as follows.
In other words, in the case of a secondary battery, a weak current in cloudy or rainy weather where the solar cell voltage is in an unstable state close to 0 V cannot be said to be a state in which sufficient current or voltage is secured to cause a chemical reaction. Power storage is not easy. In chemical reactions, voltage represents the ease of reaction, and current represents the reaction rate. During cloudy weather or rainy weather, chemical reactions are less likely to occur conditionally, and therefore the speed is slow. Accordingly, there is a case where the LED does not emit light at night because of insufficient power storage when it is cloudy or rainy. On the other hand, in the case of an electric double layer capacitor, charging is performed while gradually increasing the terminal voltage while charging a weak current even in cloudy or rainy weather when the solar cell voltage is in an unstable state near 0V. In this way, unlike the secondary battery, the electric double layer capacitor can be charged immediately if there is some voltage. Therefore, the LED can emit light every night regardless of the weather.
[0018]
In addition, a life-saving light-emitting device in which only a solar cell and an electric double layer capacitor are combined, that is, a life-light-emitting device without a dry battery as a primary battery is conceivable, but in that case, the storage method is limited. This is not desirable. That is, if the life-saving light-emitting device can be stored by a storage method in which sunlight always hits the solar cell portion, it is possible to use a life-time light-emitting device in which such a solar cell and an electric double layer capacitor are combined. However, such life-saving light emitting devices are usually stored indoors or other places where there is no sunlight. After an accident occurs, a solar cell is immediately generated and stored in an electric double layer capacitor. Because it is difficult. This is especially true if the accident occurs at night.
[0019]
3-6 is a figure for demonstrating the example of arrangement | positioning of the life-saving light-emitting device 1 which has the above structure. FIG. 3 shows an example of arrangement on a relatively small lifebuoy 300, FIG. 3 (a) is a plan view, and FIG. 3 (b) is a front view thereof. FIG. 4 shows an example of arrangement on a relatively large lifebuoy ring 400, FIG. 4 (a) is a plan view, and FIG. 4 (b) is a front view thereof. 5 shows an example of arrangement on the lifeboat 500, and FIG. 6 shows an example of arrangement on the life jacket 600. As shown in FIG. The life buoys 300 and 400 and the lifeboat 500 shown in FIGS. 3 to 5 are mainly effective in a seawater accident, etc. In the case of the life jacket 600 shown in FIG. It is also used effectively in the event of a mountain accident.
[0020]
As shown in FIG. 3, the relatively small lifebuoy ring 300 has a small surface area, so that the direction of the emitted light from the LED 21 is upward on the upper surface portion of the floating portion 310 of the lifebuoy ring 300. A plurality (four in the figure) of life-saving light emitting devices 1 are arranged so as to be. The relatively large life buoy ring 400 has a large surface area, so that there are a plurality of the life buoy rings 400 on the side surface as well as the upper surface of the life buoy ring 400 (four on the upper surface in FIG. 4), and the direction of the light emitted from the LED 21 is not only upward but also lateral or diagonally upward.
Further, as shown in FIG. 5, even in the lifeboat 500, the lifeboat 500 has a plurality of floating portions 510 on the upper surface portion and side surface portions (four in the upper surface portion, side surface portions in the drawing), like the lifebuoy ring 400. 4), and the direction of the light emitted from the LED 21 is the upper direction and the horizontal direction or the diagonally upward direction.
Further, as shown in FIG. 6, since the surface area of the life jacket 600 is small, there are a plurality of jacket parts 610 and pocket parts 620 of the life jacket 600 (two in the jacket part 610 and two in the pocket part in the figure). 2) so that the direction of light emitted from the LED 21 is upward.
[0021]
Thus, by arranging the direction of the light emitted from the LED 21 in the upward direction, the upward direction, and the lateral direction or in the obliquely upward direction, discovery from an airplane or a ship becomes easy.

In this method, the light emitting device 1 is embedded and fixed by silicon 710. In this fixing method, since a fixing hole 700 is provided in the lifesaving device in advance, it becomes a lifesaving device dedicated to implantation.
[0024]
