Description

The present invention has a function of transmitting and receiving sound and image information necessary for evacuation life outdoors and camping life in the event of a disaster such as an earthquake, flood, typhoon, etc., while in normal life. The present invention relates to a portable lighting lamp that can be used as a TV / radio receiver or an all-night light in a bedroom.

In recent years, typhoons, storms and floods, and urban or large-scale earthquake disasters that frequently occur due to abnormal weather have occurred. There are cases where you live in a situation without gas. In such a disaster, clothing, food and shelter are first secured, and lighting is necessary at night. At the same time, it is essential to acquire information such as the surrounding situation, relief, support, evacuation, and news reports.
It is well known that candles, oil lamps, and portable radios are conventionally used as such disaster response equipment, and have saved many people's anxiety at night.

Simple, safe and portable lighting is a flashlight, but it can not be used due to high light intensity, long-term use due to low electric capacity, and if it is held for a long time due to a disaster that does not know when it will occur, It will deteriorate. Therefore, lighting fixtures that can be used as a power source that can be charged using a secondary battery and can be used in a disaster have been proposed.
Patent Publication 2002-304901 Japanese Patent Laid-Open No. 2005-148593 proposes a device that lights a miniature light bulb in the event of a disaster by charging a battery with power generated by attaching solar cells to four surfaces. It will be a device that returns light to the disaster-stricken area, but this alone will not provide you with information about what is happening around you. Patent Document 2 proposes a device in which an LED lamp is installed in a tunnel, and power is normally supplied through a power line, and in an emergency, lighting or display is performed with power stored in a storage battery.

In the example of the previous literature, the electric power of lighting in an emergency is generated by using a solar cell, and the storage battery is charged and lit and discharged. In the evacuation life at the time of a disaster, the night light secures human behavior and gives a sense of security. The storage batteries used here are well known lead-based, nickel-cadmium, nickel-metal hydride, and lithium-ion batteries, and the output characteristics are improving year by year, while the battery life is present. Although the output power amount vs. cost performance of these secondary batteries does not improve rapidly, the development as a high output storage battery is continued. Even if the output power is equivalent to the cost comparison, a storage battery that is used in a load that is small and has a large output, such as a recent electric vehicle or electronic device, is very expensive.

On the other hand, what is needed in evacuation life is information. It is essential to obtain information such as relief, support, and evacuation as audio, screen, and video information so that a large number of people are worried and feared by a narrative language that is so uneasy at the time of a disaster. Although there are people who always have a portable radio in their daily lives, it is difficult to keep them as well as to secure oil lamps as a countermeasure against disasters. It is known that the effects of images using “eyes”, moving images and sound, such as televisions and mobile phones, are great for information transmission. Naturally, if there is a mobile TV at the time of a disaster, it will be a very effective support for refugees. In addition, it is desired that these power sources have a high capacity and can be easily handled for charging and discharging. However, having a portable lamp or TV for a disaster that doesn't know when will happen is considered a wasteful expense.

A storage battery is used for a device that uses a solar battery to light a lamp at night. Generally, a lead storage battery that is widely used is inexpensive but has a short life and requires maintenance such as replenishment of an electrolyte. In addition, continuing charging during normal energization causes overcharging, damages the storage battery, and may cause an accident with heat generation, so it is a measure to install an excessive current controller and heat dissipation mechanism and cost It takes. Storage batteries with good charge / discharge characteristics such as lithium ion batteries are generally expensive. And since all the storage batteries generate electricity as a result of a chemical reaction between a metal or a compound and an electrolytic solute, all storage batteries produce irreversible compounds due to repeated chemical changes in materials, resulting in a deterioration in storage capacity. In addition, when the battery is stored for a long time without repeated charging / discharging, the chemical reaction proceeds even if it is little by natural discharge, and the life of the storage battery is shortened by exhaustion of the electrode.
This is the reason why a low-cost power storage system that can withstand storage for a long period of time and has little deterioration due to repeated charge and discharge is desired.

Even if it is a device used for night lighting at the time of a disaster, it is desirable that it has a function capable of listening to earthquake information and mobile communication by radio sound or TV image during the daytime. This information device is usually overflowing in the market. However, in a condemned place where the electric power of the lamp is interrupted and there is no generator, in order to cover these electric power with the limited solar power generation and the electric power of the charging system, it is desirable that the lamp is a TV with a reduced power consumption as much as possible. . As a lamp with low power consumption, it is desirable to use an incandescent lamp and a fluorescent lamp or LED. Recently, bright display panels with low power consumption such as solid EL and organic EL have appeared. However, a product of a portable earthquake function lamp incorporating a lamp and a TV has not been put into practical use. This is because the power consumption and the price increase in the equipment that captures both separately.

In contrast to the equipment used in the event of a disaster, most of the normal time is stationary storage (just a figurine). Even if information equipment TVs and radios are always used, the concept of useless items works if they are rarely used normally, and the product is not used by many people. It is desirable that the built-in television can be used even during normal times. None of the conventional disaster lamps satisfy the above requirements.

In the present invention, an electric double layer capacitor (EDLC) is used as a storage battery that is as small as possible and light in price, cheap in price, has a large special electric capacity, has a long repeated use life, does not deteriorate even when left for a long time, and does not pollute the environment when discarded. use. It is also assumed that a simple current / voltage adjustment LSI is inserted to perform optimum charge / discharge regardless of the current / voltage and time variation.
Two methods are used to charge the battery. One is to use power from solar cells attached to the lamp unit body. Regardless of whether it is sunny or rainy in the daytime or in the morning or evening, it generates power by directly receiving sunlight or reflected light indoors, and at night, it generates power although it is weak from the indoor light. In the second method, during normal use, an adapter power supply from the power line is used to connect and charge the electric double layer capacitor in the lamp device.

In order to suppress the power of the lighting and the television, a liquid crystal television using an LED backlight with low power consumption or an organic LE television with low power consumption and light emission is used. Cold-cathode fluorescent lamps are mainly used as backlights for LCD TVs, but recently, LED light is inserted from the end face of the resin light guide plate into a panel, and the light passes through the resin plate in the direction perpendicular to the plate surface. In other words, some emit scattered light in the front direction of the panel surface. The projection for drawing and moving image production is formed by a filter formed on the surface of the light guide plate or a flashing matrix of liquid crystal. In order to use this panel as a lighting fixture, an image forming signal is cut off and set on a pure white screen.
An AM / FM radio is also installed in the equipment body. In addition, in order to use the device main body as a power source for other electric products such as a mobile phone, a connector connected to an electric double layer capacitor is attached. Install switches for lamps, information devices, etc., and adjustment switches for volume control.

Since the electric double layer capacitor used as the lamp power source of the present invention is a physical battery that does not perform a chemical reaction in principle, there is no deterioration of electrodes and electrolytes, and the lifetime is so long as to be infinite. Since the charging time can be dramatically faster than that of a normal secondary battery, even if the battery is inadvertently completely discharged, it can be charged in a short time by using the power line power. The electric double layer capacitor used in the present invention is unstable in brightness, such as sunlight and indoor lighting, and can be efficiently charged even when generating power under weak light. There is no overcharging even during normal continuous charging. When discharging, until there is no charge. In other words, even if the output voltage is used up to zero, there is no effect on the battery performance in the next use, so the battery capacity can be maximized and used. In this way, the battery power supply with a number of features is environmentally friendly and safe because there are no burdens on the earth during disposal because the material elements used are abundant and non-toxic on the earth.

The lamp device according to the present invention can be used not only in the event of a disaster but also in a bedroom in the normal time, etc. by using a panel used in a liquid crystal or an organic EL television as night illumination or as an image information device. Can be used as Use value is increased by making the device usable anytime. Even the portable reception lamp with a reception function used in the event of a disaster will appeal to many people.

The illumination lamp with a portable receiving function of the present invention uses a solar battery panel as a power source to be replenished in the event of a disaster. Considering the type of battery used, crystalline silicon has a high electrical conversion efficiency, but it is expensive, and cheap and lightweight is amorphous silicon, organic (cadmium, indium, gallium, selenium (CIGS), pigment) thin film type is there. Since the thin film type is a flexible film shape, it can be used for deformed containers. For portable lamps, small portable TV sizes are reasonable. Considering the ease of carrying and carrying, bedroom size lamps and TV sets that can be held with one hand are reasonable.
It is desirable to reduce power consumption as much as possible. Some mobile phones are bright and can display moving images. Electric double layer capacitors that serve as chargers have been rapidly developed, and 30 Wh / kg capacity class products have also appeared along with improvements in activated carbon, electrode structures, and electrolytes. Although there are various container shapes, a rectangular shape is easy to use considering the storage efficiency in the device body. A current / voltage control LSI is connected to the electrode opening of the capacitor to perform an optimum operation when connecting to the input power from the solar cell, the lamp panel, and an external device.

FIG. 1 shows the appearance of the portable illumination lamp with a receiving function of this patent, and FIG. 2 shows the arrangement of parts when the lamp is viewed from above.
The appearance of the portable lamp 1 with a receiving function is a rectangular parallelepiped 80 × 180 × depth 50, and it is a container of indigo-colored tone that is settled with a plastic material assuming that it is usually placed in a bedroom. The CIGS solar cell 2 was attached to the entire surface of one of the large areas. Since the effective area is 150 × 80, an electric power of 1.2 W / hr can be obtained during the daytime in fine weather. It was possible to charge 7-8 Wh from morning to night all day. On the other large surface of the lamp main unit, a one-segment mobile phone panel was remodeled as a moving image panel 3. The backlight of this panel uses LEDs, and when used in the illumination lamp mode, the illuminance is made brighter than during normal moving images, and the lighting method is time-sharing control of blinking in 1 KHz to save power. An electric double layer capacitor 4 of 55 × 60 × 100 was fixed in the main unit 1. The capacity was equivalent to 20 Wh, 72,000 F.
TV tuners and operation circuit modules were procured from commercially available portable TV components, and were also installed together with the AM / FM tuner receiving module as module 5 and fixed in main unit 1.

When the illumination lamp with a portable receiving function of the present invention was sufficiently charged from the indoor power line, and only the illumination lamp was turned on and discharged, it could be lit for 2 days and nights (-49 hours). When it is turned on only with the charged power of one day from the solar cell, it can be turned on only for 11 to 13 hours, but if it is turned on only at night, it can be used for one night. If it is charged in advance from the power line, it is possible to use the lamp only at night, charge it with a solar cell during the day, and turn it on for about 5 days only at night. In addition, if you want to continue living outdoors, you can use the solar battery every day for daytime lighting.
