BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sign and a structure for calling attention of a driver by lighting or flashing a plurality of light emitting diodes using a solar cell as a power source.

Signs on the corners of the road The self-illuminating signs, which are installed for the purpose of guiding the appearance of winding roads, are powered by commercial power sources and batteries, especially when used on roads without commercial power facilities. There was a lot of repair work because of the need for replacement.

That is why the self-luminous label using solar cells as a power source was designed.

(See Japanese Patent Application Laid-Open No. 52-95389, Japanese Patent Application Laid-Open No. 52-89081, Japanese Patent Application Laid-Open No. 52-89082)

As the on / off switch of these self-luminous labels, a solar cell is used as a power source for a light emitting diode and at the same time, the device is used to detect ambient light and operate the light emitting diode with the detected signal.

That is, the height of the output voltage of a solar cell is converted into a signal.

For example, when the output voltage of the daytime solar cell is high, the output voltage is charged in the storage battery, and when the output voltage becomes lower than a constant value after sunset, the discharge is performed from the storage battery so that the light emitting diode is turned on or blinks.

(Hereafter, only flashing is taken as an example)

In addition, when the output voltage of the solar cell reaches a certain value or more at sunrise, discharge from the battery is stopped, and at the same time, the output of the solar cell is charged to the battery.

In fact, the place where the self-luminous sign is installed is a place where the road is very winding or a zone where a lot of traffic accidents occur, and the installation is usually installed so that several lines are arranged in a row at regular intervals.

Because of this, only the LEDs of the self-emissive label installed in the shade of obstacles such as trees start flashing early, or even if the individual flashing cycles are constantly installed, if you see several self-emitting labels as a whole, There was a drawback that it could not provide correct traffic information, such as flashing inconsistently over time, causing embarrassment of traffic.

The present invention solves the above-mentioned drawbacks and maintains the maximum effect of using a solar cell as a power source, that is, the flashing of a self-luminous label installed so as to continue several lines in a row while maintaining the degree of freedom of installation (no power supply wiring is required). It is to provide a self-luminous sign that has a relationship to the operation to provide the correct traffic information to the traffic.

The above-described object is provided with a plurality of light emitting diodes freely flickered on the cover surface of the light emitter cover, and a solar cell module covered with the light transmissive cover on the upper surface of the above light emitter. A flashing arrangement having a flashing control signal transmitting device and / or a receiving device is achieved.

Hereinafter, an embodiment of the self-emitting label of the present invention will be described in detail with reference to the drawings.

Figure 5 shows the relationship between the output current of the solar cell module and the passage of time, Figure 5 is the same as Figure 4 showing the relationship between the output current and the change in the illumination of the sun, Figure 6 is the same as Figure 4 showing the rate of increase of the output current Figure 7 is a longitudinal sectional view showing another example of development of a transparent cover covering a solar cell module.

FIG. 8 is an explanatory view showing the function of the example of FIG. 7, FIG. 9 is a longitudinal sectional view showing a power generation embodiment of a light-transmissive cover with a light emitting diode, FIG. 10 is an explanatory view showing the function of the example of FIG. 9, and FIG. The light emitting indicator 1 is composed of a solar cell module 2, a transparent cover (cell case) 3, a light emitting diode 4, and a light emitter (hereinafter referred to as a main body case) 5.

The solar cell module 2 is a power source of the light emitting diode 4, and the material is made of crystalline silicon, amorphous silicon, gallium arsenide, polymer semiconductors, etc., and emits light when a predetermined level or more is emitted.

The translucent cover 3 is formed of a semi-elliptical shape of a translucent resin, and protects the solar cell module 2 from external air and efficiently collects sunlight into the solar cell module 2. It is for light.

The light emitting diode 4 blinks at night or when the amount of sunshine is low due to the operation of the block circuit described below.

The main body case 5 fixes the translucent cover 3, the front cover 6, reflector 7, etc. which are mentioned later, and protects the electronic circuit inside a case, a secondary battery.

In order to protect these, the main body case 5 is made of polycarbonate resin or the like excellent in weather resistance and impact resistance.

The solar cell module 2 is placed on the back of the main body case 5, and transparent resin such as ethyl vinyl acetate, silicone resin, and the like is filled on the module 2, and the module 2 is protected and fixed, and there is a transparent cover thereon. (3) is covered.

The electromotive force from the solar cell module 2 is connected to the control electronic circuit and the secondary battery via lead wires (not shown).

A plurality of light emitting diodes 4 are installed on the circuit board of only the main body case 5, and are installed so as to protrude at intervals in an annular shape on one surface of the main body case 5, and on the surface of the main body case 5. The transparent front cover 6 is provided by covering the above-mentioned light emitting diode 4 so as to be in close contact.

As a result, moisture or the like that enters from the protruding portions of the light emitting diode 4 and the main body case 5 is completely blocked.

In addition, in the center of the light emitting diodes 4, which are spaced apart from each other in an annular shape so that the self-luminous label 1 is conspicuous and easy to recognize, the reflector 7 which receives and reflects light back has the same center. It is installed.

Here, this reflector 7 is comprised from the molded article of the translucent resin using a prism lens, etc. (refer FIG. 7 and FIG. 8). The light from the light emitting source reflects this and returns to the light emitting source, that is, the structure for retroreflecting.

Therefore, when the night light is dark, the reflector 7 reflects the light from the outside of the headlights of the automobile, and the driver again draws attention by the blinking operation of the light emitting diode 4.

However, in order to prevent the external light from being reflected by the reflector 7 so that light emission of the light emitting diode 4 becomes inconspicuous, the reflector 7 is disposed inward of the array of the light emitting diodes 4 so that the influence of the external light is reduced. It is configured not to. 10 is a mounting member for attaching the main body case 5 to the support rod 11 with fixing devices 12 such as screws, for example.

And the outer surface of the main body case (5) and the transmitting device 8 for generating a control signal to flash at the same time to the other self-illuminating label (1) installed closest to the cover and for example adjacent self-illuminating signs ( A receiving device 9 for receiving the control signal of the blinking synchronously from 1) is provided.

Here, the transmitting and receiving apparatuses 8 and 9 include, for example, an assembly of an optical sensor such as an infrared "LED" and a photodiode, a transmitting antenna and a receiving antenna by FM waves, and the like.

FIG. 3 shows a structure in which such self-luminescent signs 1 are arranged at regular intervals along the guide rails of several roads.

3 is an example in which the guardrail G arranged along the curved roadside of the highway R is arranged so that the marker 1 is arranged in the same polar shape as the roadside at a predetermined interval.

In the figure, 1 'is a marker that becomes a key station (hereinafter referred to as a key station), and this key station 1' generates a signal that is automatically flashed on the light emitting diode 4 and is synchronized, delayed or reversed.

Here, when the key station 1 'generates a synchronizing signal, the blinking timing of the other indicia becomes approximately equal to the blinking timing of the key station 1'.

In addition, when the delay signal is generated at the key station 1 ', the other signs are delayed in sequence in order to be flashed, and when the inverted signal is generated, the indicator group having the same blink timing as the key station 1' and other indicator groups flash alternately.

1 'is a relay for receiving the outgoing signal from the key station 1' and causing the light emitting diode 4 to flash and transmitting the same frequency signal as the outgoing signal of the key station 1 'to the adjacent indicia (hereinafter referred to as a repeater). to be.

1 ″ 'is a label disposed at the end (hereinafter, referred to as an end group), and receives only the signal of the repeater 1 ″ or the key station 1' and blinks only the light emitting diode 4.

However, when the key station 1 'transmits to the terminal group 1 "', it is a case where the structure which does not have a repeater is expected, and a case where the pick-up label is two of a total of the key station 1 'and the terminal group 1"'.

Next, a block circuit diagram of the self-luminescence label will be described with reference to FIG.

FIG. 2A is a block circuit diagram of the key station 1 ', which is a block circuit diagram of the repeater 1 ".

The block circuit diagram of the end group 1 "'is almost the same as that of the repeater 1", but there is no transmission means 8 or the like since there is no sign to transmit a signal.

In addition, the common part in 2a and (b) has attached | subjected the same code | symbol.

First, a circuit common to both block diagrams will be described.

The solar cell module 2 mounted on the upper part of the main body case 5 is connected to a secondary battery 14 such as a Ni-Cd battery housed in the pole 11 via the backflow diode 13.

Here, the secondary battery 14 accumulates the generated electric power of the solar cell module 2 and also serves as a reserve when the light emission disable state is continued for one day.

The positive electrode of the secondary battery 14 is connected to the P type terminal of the light emitting diode 4 via the light emission control circuit 15, and the negative electrode of the secondary battery 14 is connected to the N type terminal of the light emitting diode 4. do.

In this way, the forward bias voltage is applied to the light emitting diode 4.

The light emission control circuit 15 starts to operate by inputting two signals, a signal from the clock circuit 16 or the demodulation circuit 17 and a signal from the lighting discrimination circuit 18, which will be described later. A multivibrator, a switching transistor current control resistor, and the like, in the present invention, a light emitting diode having a very high brightness that is lit by a red or orange light is turned on at a frequency of 40-120 times / min.

In FIG. 2A, in the solar cell module 2, the voltage signal a by the generated electric power is input to the lighting discrimination circuit 18. In FIG.

The lighting discrimination circuit 18 compares the voltage signal with the reference voltage in the circuit and selects a switching signal b 'for operating the clock circuit 16 when the voltage signal a is equal to or less than a predetermined reference voltage. 19) outputs a switching signal b "

That is, when the environment becomes dark, such as in the evening or on a cloudy day, or when the power generation voltage of the solar cell module 2 decreases, the voltage signal a becomes less than the reference voltage, so that the lighting determination circuit 18 switches the switching signal b '. ) And (b ") are generated in the circuit, respectively.

In addition, instead of detecting the generated voltage of the solar cell module 2 like this lighting discrimination circuit, you may use the photodetecting sensor comprised from cds etc. which are not shown in figure.

The switching signal b 'is input to the clock circuit 16, which outputs block signals c' and cc which transmit at 40-120 times / min.

Here, the block signal c 'is input to the light emission control circuit 15, and the block signal c "is input to the modulation signal generation circuit 19.

Accordingly, the light emission control circuit 15 causes the light emitting diode 4 to flash in synchronization with the clock signal c '.

On the other hand, the modulation signal generation circuit 19 to which the switching signal b "and the clock signal c" are input is a circuit which generates the modulation signal d synchronized with the clock signal c ", and the modulation signal ( d) is a signal in synchronization with the blinking of the light emitting diode 4, a delayed signal or a signal inverting the blinking operation of the light emitting diode.

In response to the modulation signal d, the infrared LED serving as the transmitting means 8 emits light, and the signal is cut by the repeater 1 "or the terminal 1" '.

The modulated signal d generated as the infrared LED, which is the transmitting means 8 of the key station 1 ', emits light is received by the receiving means 9 made of an optical sensor or other light receiving element in the block diagram shown in FIG. .

Subsequently, the received modulated signal d is removed through a high pass filter in the demodulation circuit 17 or the like so as to remove noise components so as not to cause malfunctions with light of commercial frequency from natural light or other lighting. e)

Here, the demodulation circuit 17 detects a frequency within a predetermined time of the input signal d, for example, and is the modulation signal d a synchronous signal which emits light in synchronization with the light emitting diode of the key station 1, It is determined whether the signal is a delay signal or an inverted signal.

That is, in the key station 1 ', for example, only the time T2 (where T1> T2) is transmitted at a time interval of T1, so that the modulation signal d at a predetermined frequency is transmitted. ) And count the type of modulation signal d from the magnitude of this frequency.

In addition, the modulation signal d is inputted according to the magnitude of this frequency, and it is determined how long the light emitting diode 4 is to be emitted.

In this case, when the modulation signal d is an inverted signal, information indicating that the light emission timing is delayed by, for example, Tl / 2 from one label to another is sequentially transmitted, and the label group flashes at the same timing as the key station 1 'and the other. Marker group flashes alternately.

For simplicity, the modulation signal d will be described as a synchronization signal.

Subsequently, the demodulation signal e and the switching signal b '(provided from the lighting discrimination circuit 18 only when the power generation voltage of the solar cell module 2 falls below a predetermined value) are respectively emitted from the light emission control circuit. When inputted to (15), the light emission control circuit 15 flashes the light emitting diode 4 in synchronization with the demodulation signal e.

As a result, the light emitting diode 4 of the key station 1 'and the light emitting diode 4 of the repeater 1 "are synchronized.

Here, when the power generation voltage of the solar cell module 2 is greater than a predetermined value, only the demodulation signal e is input to the light emission control circuit 15, so that the light emitting diode 4 does not blink.

In addition, in the repeater 1 ", the switching signal b" output from the lighting discrimination circuit 18 and the demodulation signal e output from the demodulation circuit 17 are simultaneously modulated signal generation circuit 19 at the same time as the start of the flashing. ) Is entered. The modulated signal generating circuit 19 generates a modulated signal f and emits an infrared LED which is the transmitting means 8 of the modulated signal f toward the adjacent repeater 1 "or the end group 1" '. It emits light.

In addition, in the terminal group 1 "', if the receiver 9, the demodulation circuit 17, and the light emission control circuit 15 are provided, they are synchronized or delayed with the light emitting diodes of the key station 1' and the repeater 1". Black can be inverted and flashed so no demodulation circuit or infrared LED is required.

In the repeater 1 "and the end group 1" ', the power generation voltage signal a of the solar cell module 2 and the lighting discrimination circuit 18 are abbreviate | omitted, and the demodulation in the demodulation circuit 17 is carried out. The light emitting diode 4 may be flickered only by the signal e or the modulation signal generating circuit 19 may be operated.

In addition, in the above-described block circuit diagram, an infrared LED and an optical sensor are used as the transmitting means and the receiving means. The antenna may be used as the receiving means, and each marker may be flickered while receiving FM waves of a predetermined frequency.

Further, a plurality of infrared LEDs having high directivity may be used as the transmitting means in the key station 1 'so that all other indicators receive the flashing signal generated by the transmitting means.

However, in the case where the FM wave is used or when the transmitting means is provided only in the key station 1 ', the above-described repeater 1 "does not need to have a transmitting means, and only the receiving means needs to be provided.

If the signal from the transmitting means is a delayed or inverted signal, information on the timing of blinking according to the frequency of the signal (for example, information on how long the delay is to start blinking after reception) is previously displayed for each marker. It must be set.

Also, as described above, there may be a structure of two marks in total, such as a key station 1 'and a terminal group 1 "' provided only with the receiving means, depending on the length of the mark line.

When the present invention self-emitting signs configured as described above are installed so as to continue in a row, centered on the self-illuminated signs of the key station, they may be alternately blinked and the road is in a tortuous state due to regular flashing. Correct traffic information such as sudden curves can be viewed and confirmed to passers-by.

In addition, even when self-illuminating signs other than the key station 1 'installed at sunset are shaded by trees or road buildings, the key station 1' is kept at a higher voltage than the operating voltage by solar radiation. Therefore, the other self-luminous label cannot obtain a modulated signal from the key station 1 'and does not start blinking.

In this manner, as in the prior art, the solar sensor having the self-illuminating label has a wrong operation, thereby preventing the problem of blinking the self-illuminating label having a shade.

As described above, the present invention can provide a series of linkages to the flashing operation by providing a device for transmitting and / or receiving a signal for controlling the period of lighting or flashing of the light emitting diode on the self-emitting label installed in several ways. In this way, the right traffic information can be given to passengers.

In addition, several self-luminous labels can be lit and blinked at the same time, making it easier to recognize.

Next, the developmental embodiment of the label structure of the present invention will be described.

(I) Translucent cover 3 covering the solar cell module: (a) The shape is almost semi-elliptical (first degree) or approximately hemispherical, and the solar cell module 2 is turned on ( When the surface is attached to the upper surface of 1) in a substantially flat shape, the cover can be installed anywhere without considering the direction of the sun's incidence or the altitude of the cover 1, At the same time a high output voltage is always obtained.

In order to confirm this benefit, the following three test results are added.

The solar cell module 2 is installed horizontally on the upper surface of the lighter 5 of the cover 1, and the translucent cover 3 of the semi-elliptic shape of which the light receiving surface is round (R = 25mm) (silicone resin or The comparison was carried out between the solar cell module A provided with ethyl vinyl acetate) and the solar cell module B provided with the solar cell module 2 horizontally without a cover.

In addition, the solar cell module ^{2 having} a light receiving area of about 30 cm ² at the center of the top surface of the cover was about 50 cm ² .

) 호남지방에서 측정한 것이다.All the data shown in FIGS. 4 through 6 are Japanese Shiga (껜) on a clear day near March 21 (

) Measured in Honam province.

4 shows a change in the output current of the solar cell module A provided with the transparent cover 3 and the solar cell B provided only in a planar shape.

The horizontal axis represents time change, that is, from sunrise to sunset, and the vertical axis represents output current.

As a result, it can be seen that the solar cell module A provided with the translucent cover 2 obtains a high output current by the excellent light condensing ability regardless of the sun position and altitude.

5 shows the output current of each of the solar cells A and B in the change in the illuminance of the sun.

The horizontal axis represents the illuminance of the sun, and the vertical axis represents the output current.

As a result, it can be seen that the output current of the solar cell module A is always 15 mA-25 mA higher than the output current of the solar cell module B, regardless of the illuminance of the sun.

FIG. 6 shows the change of the increase rate of the output current of the solar cell module A provided with the light-transmissive cover 3 with respect to the output current of the solar cell module B provided only in planar shape according to the illumination of the sun.

The horizontal axis represents the illuminance of the sun, and the vertical axis represents the increase rate of the output current of the solar cell module A with respect to the solar cell module B, respectively.

As a result, it has been found that the solar cell module A has excellent output characteristics in low illumination, such as when the sun is low, when the weather is impure, or where it is difficult to receive direct sunlight due to obstacles.

As can be seen from FIG. 4 to FIG. 6, the incident direction of the sun is provided on the limited back surface of the cover 1 by installing the solar cell module 2 covered with the translucent cover 3 of the semi-elliptic shape with rounded light receiving surface. In addition, it is possible to always obtain a higher output current than in the prior art without considering the altitude, and in particular, it is possible to obtain a very excellent output current even in low illumination of the sun, such as when the solar altitude is low or when the weather is cloudy.

(b) As shown in FIG. 7, the front portion of the transparent cover 3 extends over the cover surface to form a translucent stretched portion 20, and the light reflecting layer 21 is formed on the top of the stretched portion 20. The solar cell module 2 can also be operated even when snow or dust accumulates on the cover 3.

That is, the surrounding solar light γ incident from the outer surface of the portion 20 extending as shown in FIG. 8 is formed on the rear surface of the portion 20 extending through the thick portion of the portion 20 extending therethrough. ) Is a total reflection. Moreover, it reflects again to the surface interface of the part 20 which extended straight through the thick inside.

That is, the light is incident on the thick inner side of the extended portion 20, and eventually the sunlight incident from the outer surface of the extended portion 20 is conducted into the transparent cover 3.

As a result, for example, the snow (or dust) S is thickly accumulated on the light receiving surface of the transparent cover 3 of the solar cell module 2 and is incident from the outer surface of the extended portion 20 even if sunlight does not enter. The solar cell module 2 obtains an output voltage by conducting the light from the portion 20 from which the sunlight extends into the transparent cover 3.

(II) Translucent cover 6 covering the light emitting diode 4: Among the translucent covers 6 covering the light emitting diode 4 as shown in FIG. 9, the upper and lower portions of the light emitting part 40 of the diode 4 and the adjacent portion thereof. If the reflective layer 22 of the light is formed by leaving the area of the light emitting portion 40 described above on the back side between the light emitting portions 40, the cover surface can be effectively utilized by using the light of the light emitting diode with low current consumption but narrow optical directivity. Since the front or main part seems to be emitting light, it is easier to recognize as a sign, thereby preventing traffic accidents.

That is, in the case of the above-described configuration, when a current flows in the light emitting diode 4 as shown in FIG. 10, the lighting light is emitted from the chip (light emitting point) of the light emitting part 40 protruding in the above-mentioned light-transmitting cover 3. do.

For example, the lighting light γ ₀ emitted from the front of the chip goes straight inside the cover 6, and at the surface interface of the cover 6, a part of the lighting light γ ₀ transmits outwardly (transmission light γ ₁ ) and the rest of the lighting light γ ₀ . Is reflected, and the primary reflected light γ _{1 which} is again traveling straight into the cover 6 is totally reflected in the reflective layer 22 installed on the back of the cover 6, and the totally reflected secondary reflected light γ ₂ is again inside the cover 6. Proceeding straight, surface interface transmission (transmitted light γ ₃ ) and reflection (third reflected light γ ₃ ) of the cover 6 occur.

That is, the lighting light in all directions emitted from the chip of the light emitting part 40 diffusely reflects at least in the thick of the cover 6 covering the area between the upper part of the light emitting part 40 and the adjacent light emitting part 40. As a result, the cover 6 of the cover surface appears to emit light over the entire surface.

This greatly improves the driver's visibility.

The development form of the above label can thus be preferably applied to the label of the present invention and the label structure of the present invention.
