The present invention relates to an evacuation induction device that can safely evacuate a person in an emergency such as a fire, and more specifically, evacuation induction lamps are installed in a braille sidewalk block for persons with disabilities installed on large building floors, subway floors, and public building floors. This allows the visually impaired as well as non-visually impaired persons to evacuate safely along the braille walkway block with induction lamp function in the event of a power outage due to a fire. It is to be supplied as usual emergency light and in case of emergency, the microchip flashes the battery power five times per second by the signal of the sensor so that the evacuation direction can be easily and safely evacuated. It relates to a braille block for evacuation guidance lights.

At present, emergency exit induction lamps and visually impaired facilities installed in large buildings, subways, public buildings, etc. in Korea are often installed in a form, and thus there is a problem that the functions cannot be normally operated so that people can be evacuated safely in case of fire.

For example, after the Daegu subway fire occurred, the public authorities and the public voiced their efforts to replace evacuation facilities and fire-hazardous facilities in the subway or public places with strong fires, but due to lack of continuous research and economic reasons. Because of this, the situation is only unpaid.

In other words, in the current evacuation facility installed in the subway, the case where the luminous tape and the luminous paint are installed on the floor or the wall by the evacuation guidance lamp, and the ordinary emergency exit guidance lamp is installed at the bottom or the middle part of the wall. This may be effective as an evacuation induction device to some extent in the dark without fire, but in case of an emergency due to a fire, the hearing of the person is urgent and embarrassing. In addition, the screen door has a significant effect on preventing people from getting hurt when the train enters. In the event that a fire breaks out on a train, all the power supplies have become useless, it is difficult for passengers to open the subway doors manually and then open the screen doors manually. Therefore, when screen doors are installed, research and countermeasures are urgently needed for facilities that allow passengers to evacuate safely in an emergency, just as passengers gather in a tunnel with fire.

In addition, conventionally, induction lamps installed to induce evacuation in case of fire in subways, large buildings, public buildings, etc. are installed on walls, ceilings, doors, and the like, and braille sidewalk blocks are installed on the floor to guide the blind. Looking at this prior art,

The tactile fluid is a luminous pigment formed by mixing 85% glaze and 15% luminous pigment. It is formed by mixing 80% water with 20% mixed glaze, and the tactile surface layer is formed by curing the magnetic braille block coated with the tactile fluid on the entire upper surface at a temperature of 200-1200 ° C. for 2-8 hours. Braille Block ",

Utility model registration No. 297394 of the upper plate and the lower plate formed with air vents formed of the braille projections are formed of a thermoplastic synthetic resin material, the inside of the upper plate and the lower plate to form a plurality of ribs and fastening protrusions and fastening holes corresponding to each other, the upper plate By integrally forming the bottom and bottom plate by ultrasonic welding, it is not easy to be discolored and does not require separate detachment and sorting work during recycling, and it is easy to recycle, and a considerable space is formed inside the braille block to prevent overweight. The production, transportation and construction of the block is efficient, while a plurality of ribs corresponding to the inside of the upper plate and the lower plate are formed to be excellent in durability, and ventilation holes are formed in the lower plate to prevent deformation due to the expansion of the internal air of the braille block. Synthetic braille blocks,

In contrast to the existing Braille blocks of Utility Model Registration No. 351459, which only functioned to help the visually impaired walk, the present invention adds to the basic functions for public or commercial advertisements, announcements, schemes, etc. In addition to the visual effect for the power outage or fire in order to have a safety induction and evacuation function by a fluorescent plate containing a phosphorescent pigment, the braille block is manufactured by separating the bottom plate and the top plate coupled to the bottom plate, and the top plate and the bottom plate Insert a fluorescent plate formed by mixing a fluorescent brightener and a phosphorescent pigment with a resin in between, and install a fluorescent plate, and have an uneven shape around the lower surface of the upper plate and the upper surface of the lower plate to prevent water or dust from flowing through the upper and lower plates. Braille capable of advertising or safety in the form of double coupling protrusions and coupling grooves It is those disclosed on the lock.

All of the above prior arts have braille blocks for inducing paths to the visually impaired and have a protrusion on the upper surface, or induce evacuation using fluorescent sheets and fluorescent pigments.

However, the braille sidewalk block of the above configuration can guide the way for the visually impaired to ride the entrance or subway like the usual sidewalk block, but it has a disadvantage in that it does not function at all in the event of a power failure in the event of a fire. .

That is, in the case of using a fluorescent pigment coating or a fluorescent pigment sheet in a braille sidewalk block, if people step on the foot while trying to escape from each other in an emergency, the fluorescent painting becomes useless. In particular, when smoke is generated and toxic gas is generated, soot and dirt are buried in the sidewalk block, so there is a problem in that it cannot be used as an evacuation guide device in an emergency.

The present invention was devised in view of the above problems, and the LEDs, solar panels, sensors, accumulators, and microchips were installed inside the braille sidewalk block made of transparent synthetic resin so that the LEDs flicker in an emergency so that evacuators can easily identify them. By accumulating and storing the lights in the room to receive power in case of emergency, it is possible to supply the power for a long time without using the power input to the building. It is intended to be able to evacuate or hear sound and to evacuate quickly.

The present invention having such a purpose is made of a transparent or semi-transparent synthetic resin panel and forms protrusions and grooves on the top and bottom surfaces, and induces emergency by circuit boards and storage batteries with a plurality of LEDs, solar panels, sensors, and microchips installed in the grooves. By constructing the device, the microchip repeatedly flashes the battery power five times a second in response to the sensor's signal in case of an emergency, providing a braille walking block for both evacuation induction lamps that allows people to easily and easily evacuate. It is.

Hereinafter, an embodiment of the present invention will be described in detail.

In the braille sidewalk block that is installed to guide the way of the blind and visually impaired to guide evacuation in case of fire,

Braille walkway block 10 made of a transparent or translucent synthetic resin panel and the protrusion 11 and the groove 12 is formed on the top and bottom;

An emergency induction device includes a circuit board 17 and a storage battery 18 on which a plurality of LEDs 13, a solar panel 14, a sensor 16, and a microchip 15 are installed at the bottom of the braille sidewalk block 10. do.

In the LED, the recess 12 of the bottom of the braille sidewalk block 10 is installed in the form of a symbol or a letter, and the other recess 12 is provided with a solar panel 14.

One side of the bottom surface of the braille sidewalk block 10 is provided with a sound generating unit 20 is configured to generate a sound stored in the microchip 15 in an emergency.

In addition, the case 19 is installed on the bottom of the braille sidewalk block so that the circuit board and the battery can be embedded. The case may or may not be installed depending on the environment of the braille sidewalk installation site.

The present invention configured as described above usually collects light by the solar panel 14 of the solar cells installed in the bottom recess 12 of the braille sidewalk block 10 made of transparent or translucent panels, and converts the power into a power source for the storage battery 18. While supplying power to the battery.

The LED 13 is arranged in the form of a letter or a symbol in the recess 12 of the bottom surface of the braille sidewalk block 10 to receive the power of the storage battery 18 to maintain the light emitting state.

As described above, the solar panel 14 accumulates power to the battery and emits the LED 13 at the same time as the lamp light installed in the room, and is connected to the microchip 15 when the lamp in the room is turned off during a fire or power failure. As a result of sensing the power failure by the sensor 16 installed on one side of the bottom surface of the braille press block 10, the LED 13 is turned on by the power of the storage battery 18.

At this time, the microchip 15 supplies power to the LED 13 by the signal of the sensor 16. The power of the LED 13 blinks 5 times per second to supply the power, and the light of the LED 13 blinks to evacuate the exit port. Or try to get out.

At this time, the storage battery 18 stores the light of the indoor lighting by the solar panel 14, but when the power is not supplied or fired by the fire lamp, the power to store the power for about 10 hours.

The present invention uses a small amount of power unlike an ordinary fluorescent lamp by using an emergency induction lamp as the LED 13, so that a power source that can use 10 LEDs 13 for 3 hours when the battery is a 3V battery is used.

In addition, unlike the fluorescent lamp, the LED 13 does not affect the shortening of the life of the LED 13 even if the power is supplied to blink about five times per second.

 The present invention forms a sidewalk block made of transparent or translucent synthetic resin, so that the light is well visible, making it easier for people to identify, and a protrusion 11 is formed on the upper surface to guide the visually impaired. It is.

1 is a cross-sectional view of the evacuation induction lamp is installed in the interior of the braille walkway block of the present invention, forming a braille walkway block 10 made of transparent or translucent synthetic resin, but forming a plurality of protrusions 11 on the upper side of the braille walkway block Install with flooring to guide the blind.

In other words, subways, large buildings, public buildings, etc. are obliged to install emergency exit guidance lamps to evacuate in case of fire, and facilities for persons with disabilities should be installed so that all persons with disabilities, including the visually impaired, can enter and exit.

However, since the emergency exit induction lamp installed in the present building and the road guidance device for the disabled are separately installed, the emergency exit induction lamp and the visually impaired person have to be used in consideration of the inconvenience of the work, construction cost, and excessive administrative cost. Invented to use the road guidance facilities together, LED (13) instead of the existing fluorescent light and power is supplied to the power source by using solar light or indoor lighting instead of the power supplied to the building It is possible to supply power in case of emergency.

The light emitting diode (LED) used in the present invention refers to a semiconductor device in which electrons move from a high energy level to a low energy level through electric electricity and emit light of a specific wavelength.

 Unlike conventional light bulbs, LEDs consume very little power at a level of 1/12, and their lifetime is over 100 times faster than light bulbs and 1000 times faster than electricity. It is also in the spotlight for displays such as electronic displays.

In other words, the luminescence phenomena that occur when a voltage is applied to a semiconductor is called electric luminescence (electroluminescence), and it is derived from the observation of luminescence of silicon carbide crystals in 1923. In 1923, a high luminescence efficiency at a gallium arsenide pn junction was observed. Since the discovery, the research has been actively conducted. By the end of the 1960s they were put into practical use.

Suitable materials for the light emitting diode include ① light emission wavelength in the visible or near-infrared region, ② high luminous efficiency, and ③ production of pn junctions. Groups 3B and 5B, mainly gallium arsenide GaAs, gallium phosphide GaP, gallium-arsenide-phosphorus GaAs1-x Px, gallium-aluminum-arsenic Ga1-xAlxAs, indium phosphide InP, indium-gallium-phosphorus ln1-xGaxP Elemental or ternary compound semiconductors are used, and research is also being conducted on 2B, 6B, 4A, and 4B groups.

LEDs have different colors depending on which compound semiconductors (GaP, GaAs) are used. LEDs that emit red or green light were developed decades ago and are widely used in various industrial and household appliances.

Humans can see the color of light when the wavelength of the light is in the visible range between 400 and 700 nm (nanometer: 1 billionth of a meter). In the case of red, 700nm and green are seen at relatively long wavelengths of 565nm, but in the case of blue, they are seen at short wavelengths of 400-450nm.

LEDs were developed in the order of red-green-blue because shorter wavelengths make it difficult to develop compound semiconductors that produce light.

The world's major research institutes have succeeded in developing long wavelength green-blue devices of more than 500nm using selenium (Se) or silicon carbide (SiC) to produce blue, but have not succeeded in developing high-brightness blue LEDs below 450nm. Eventually, after a number of research institutes, Nakamura's research team at Nichia Corporation in Japan succeeded in developing a high-brightness blue LED with a short wavelength of less than 450 nm using gallium nitride (GaN).

Until blue LEDs were developed, they did not achieve full color. This is because three colors, red, green, and blue, are needed to make full color. So if you look at the display boards before the blue LED comes out, you can see yellow or red color because it is made with only red and green LEDs.

Since the development of blue LEDs, however, the use of RGB (Red / Green / Blue: used for TVs or monitors), which can produce all colored lights, allows the user to see a perfect color sign.

In addition, the demand for blue LEDs is exploding in the industrial field by applying various LEDs such as optical memory devices or home appliances requiring short and stable wavelengths.

Looking at the prospects of such LED industry, the development of LED has led to the development of new applications such as full-color LED signs using red, green, and blue or LED signals that are clearer and have less reflection than existing signals.

In particular, incandescent bulbs, which are existing light fixtures, consume 90% of the electrical energy and 70% of the fluorescent energy as thermal energy, which consumes a lot of energy.However, in the case of light emitting diodes, almost 100% of the electrical energy can be converted into light energy. Emerging as a new luminaire to replace an existing light bulb

The light emitting mechanism is largely divided by recombination of free carriers and recombination at an impurity emission center. By recombination of free carriers, the emission wavelength is approximately ch / Eg (c is the luminous flux, h is Planck's constant, and Eg is the energy width of the forbidden band), and in the case of gallium arsenide, it becomes near infrared light of about 900 nm. In gallium-arsenic-phosphorus, Eg increases with increasing phosphorus content, making it a visible light emitting diode.

The light emitting diode is smaller in size than the conventional light source, has a long lifetime, and has low power and good efficiency since electrical energy is directly converted into light energy.

In addition, it is used in display devices of automotive instrumentation, display lamps of various electronic devices such as optical communication light sources, numeric display devices, and card readers of calculators. In addition, the implantable semiconductor laser is a kind of light emitting diode having a very high implantation density, and an inverted distribution can be generated to generate coherent light.

The present invention focuses on the advantages of these LEDs, allowing them to evacuate more easily and quickly in emergencies while prolonging their lifespan, while the smoke rises to the top in the event of a fire, while people bend their backs to avoid the smoke. We applied it to the sidewalk block considering the posture.

Therefore, the existing blind guided braille sidewalk blocks installed on the subway floor are installed every two or three, so that they can be used as road guide blocks for the blind and usually used as evacuation guides for emergencies.

The present invention as described above forms a protrusion 11 on the upper surface of the braille footpath block made of transparent or translucent synthetic resin so that the visually impaired can use it as a road guide braille, and the inner bottom has a plurality of portions corresponding to the upper protrusion 11. To form the groove 12 of the LED 13 and the solar panel 14 to receive light and convert it into a current to be used as a solar cell is installed.

The LED 13 and the solar panel 14 are installed and connected to the lower circuit board 17, and the control thereof is such that a command can be transmitted by the microchip 15 installed at one side of the circuit board 17. The plurality of LEDs 13 and the solar panel 14 are installed on the circuit board to be electrically and electronically operated by the conventional connection configuration.

In addition, the sensor 16 is connected to the microchip 15 to detect that there is no light in case of power failure, and sends a signal to the microchip 15, and the microchip 15 again supplies power of the battery 18 to the LED 13. The microchip 15 controls the power supply method so that the power supply is turned off and then supplied 5 times per second so that the LED 13 blinks so that evacuators can easily identify the power supply.

It is connected so that each device can be controlled.

Particularly, the storage battery 18 stores power by storing the power by the solar panel 14 and simultaneously supplies current to the LED 13 to emit light.

At this time, the LED 13 does not flash and maintains a lit state, and the sensor does not operate while the lamp is turned on.

In addition, the solar panel 14 plays a role of converting the illumination light of the room into the current, which is a state that is applied to the conventional technology or the emergency induction of the room has no state.

In addition, because the solar panel 14 is installed in the recess 12 of the bottom of the braille sidewalk block is small and installed in order to maximize the efficiency of the current.

The battery used in the present invention uses 3V, and the stored 3V becomes a capacity capable of lighting one braille sidewalk block for 10 hours.

When the signal is applied to the microchip 15, the microchip 15 supplies the current in a blinking state to the LED 13 side and simultaneously outputs a signal to the sound generator 20 so that sound is generated. To evacuate following sound and LED lights.

The sound of the sound generator 20 selectively stores human voice, melody, warning sound, and the like, so that the sound is generated by the signal of the sensor 16.
