Description

Traffic sign board using optical fiber and solar cell {The tarffic light display board by using}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a traffic sign using an optical fiber and a solar cell. Specifically, the present invention relates to a light source having a low power consumption and high luminance, and a flexible optical fiber (or optical cable). By using the total reflection principle, cover patterns such as figures, letters, and numbers can be changed to a single color or various colors to improve the monotony of existing signs or signs and use less power than existing traffic signs with low efficiency lighting means. A big traffic sign effect can be obtained.

In general, existing neon signs or traffic signs that require lighting means are expensive and low-efficiency lighting sources, such as light-emitting diodes or neon signs (neon lamps) or fluorescent lamps (or light bulbs) with high power consumption and low brightness. Because of its relatively short lifespan, the replacement cycle is also short, and there is a problem that the labeling effect is monotonous because it is a simple light.

In addition, it uses AC power of 220V or higher, which may cause a short circuit or electric shock, and there is a difference depending on the degree of humidity or snow or rain, but there is a loss of power due to a short circuit and a neon lamp or a fluorescent lamp that is relatively weak to impact. If broken, there is a problem leading to failure.

In addition, since the use of a general commercial power, there is a problem such as using a separate battery boosted by the inverter in the case of a mobile traffic sign has a problem such as complicated configuration and heavy weight.

On the other hand, the optical fiber transmits the incident light efficiently to the desired destination while repeating total reflection or zigzag as is well known, and even though the flexible fiber is bent, there is a characteristic that the light proceeds in the fiber without loss. .

Therefore, the present invention uses the total reflection principle of the optical fiber to express various contents in one light source, make various colors and various changes to improve the monotony of the existing optical display device and improve the luminous power of high brightness with a small number of power consumption. It is an object of the present invention to obtain a large light display effect with less power than a conventional light emitting diode, a neon lamp or a light bulb by using a light source having a light source.

The present invention can dramatically change the existing optical display panel using the optical fiber. In particular, high-brightness LEDs can be used to replace the existing high-cost, low-efficiency neon lamps and lighting devices of various signs, so that the maximum effect can be obtained. Provide traffic signs that can be captivated.

In addition, the present invention uses the total reflection principle of the optical fiber to express the various contents in one light source, to make various color changes to improve the monotony of the traffic sign and to use a small number of light sources to the existing neon signs or signs Compared to this, it is possible to obtain a great effect with less power.

In addition, the present invention has a relatively simple structure.

On the other hand, the physical properties of the optical fiber include a clad of low refractive index on a high refractive index core to gradually reduce the refractive index from the center to the step index type in which the light absorbing jacket is accommodated. There is a graded index (distributed index of refraction) type, which transmits up to about 99.9% of the incident light to the destination while repeating total reflection at the interface between the core and the clad.

In addition, if the cut surface of the optical fiber is uneven, light rays are scattered and it may not have sufficient effect, so it is more effective to cut it evenly with a sharp blade, or to polish the end surface by moistening the cloth with an abrasive for acrylic resin or pressing the end face on the heated glass surface. In order to cut a large amount of optical fiber at once, use a hot knife to even out the cut surface of the optical fiber.

Hereinafter, the preferred technical configuration and operation of the present invention will be described in detail with reference to the accompanying drawings.

The driver's feelings on the highways and national highways during rainy weather and at night may be the heart of a car-racer who raises his eyes and stunts the dark front like a surprised rabbit. The question is, how do you get the driver's watch?

In order to solve this problem, various facilities are installed on the road, and a lot of time and manpower are invested in developing more effective products, and products that incorporate new technologies are showing up.

In general, road lighting requirements

First: Is the luminance uniformity of the road surface appropriate?

Second: Is there enough glare so that there is no disturbance and discomfort of visual information by scattering of light?

Third, it is ideal when it has proper induction.

This emphasizes that the lighting applied to the road should not be limited to instantaneous visual information, but should be recognized by the driver as visual information with predictable continuity that changes over time. In addition, if you summarize the role of road lighting,

First: not only basic functions as information to reach the destination,

Secondly, information for normal safe driving

Third: information on situations requiring special driving

Fourth: Information to recognize the existence of a risk situation in advance

Fifth, the function can be classified into timely information about an emergency or information to prevent an emergency.

To digest these functions, above all, the development of technology and new materials that can perform delicate display functions are necessary.

Conventional traffic signs play a certain role for the purpose of displaying road conditions such as construction sections, constant speed driving, obstacles, etc., but the location status was relatively short-distance, so there are many problems with the emergency warning function during high-speed driving or at night rainy weather. there was.

The present invention is a technology for making a more stable road conditions with the various functions as described above, and can easily grasp the road situation in preventing and controlling all risks and obstacles occurring on the road, ensuring safe and smooth traffic and inducing the driver's eyes. It is a display device technology developed in order to fundamentally reduce the lives and property from the increasing number of traffic accidents by ensuring a comfortable driving. As such, many problems cannot be enumerated, but the present invention requires a clear marker so that the driver can recognize dangerous situations, guidance signs, and speed conditions even at a long distance. The technology was developed to prevent accidents in advance.

In addition, the present invention is a technology that applied the optical fiber to the road traffic sign, in particular, the light emitting diode (8,000 ~ 20,000mcd) having a high brightness of the light emitting power and low power consumption by the solar cell combined with the "regulation", It is a display device technology developed so that the driver can recognize the sudden curve, dangerous danger, and speed of the road effectively during rainy or night driving by applying to the indication and caution signs. . In addition, the present invention is a safety sign (speed regulation, danger sign during construction) that is applied in order to prevent accidents that may occur in advance by notifying drivers and pedestrians of dangers that may occur in various road construction and road danger areas in advance. It is possible to protect construction equipment and human life and property caused by accident by incorporating new materials and technology on the gull sign, etc.) To this end, the output of the oscillator circuit amplifies the signal of great power and emits high luminance on the light emitting part. The device uses LEDs, and the light emitting part and the signage use the optical fiber which has almost no loss to connect and transmit the blinking light, so that the driver can easily recognize the road situation even at a long distance and have a great effect on safe driving and accident prevention. It is also a technology that maximizes the unique function of the safety signboard. 1 is a configuration diagram of the present invention, a solar cell (SE) that receives sunlight (SL) incident from the sun during the day and converts it into electromotive force, and charges the electromotive force generated from the solar cell and the circuit and light emission Storage battery (charger) (B) to supply to the device, reverse current prevention diode (D) to prevent the electromotive force of the battery from flowing back to the solar cell, and to detect the ambient illuminance to activate the circuit when dark and stop the operation when bright Solar light detecting control unit A, which is an illuminance switch, an oscillating unit C having a flashing circuit, an amplifying unit Q for amplifying the oscillating signal with greater power, and high brightness (8,000 to 20,000 mcd) for easy identification ) Is largely composed of a light emitting portion L composed of a plurality of color light emitting elements, and an optical fiber PC for transmitting the flashing light of the light emitting portion L to the sign F. In addition, it is possible to use a distribution line instead of a fiber optic (PC), but not only is there a lot of power loss due to internal resistance, but also a large capacity distribution line (a large diameter distribution line) is required as the power consumption of the load increases, and the light emitting element is directly displayed. There are some problems, such as the need for a large amount of light emitting elements to be attached to, but in the case of using the optical fiber as in the present invention, all the flickering light generated from the light emitting part (L) is transmitted to the sign F without loss. It is not limited to the (light quantity), and there is an advantage that the signs of complex contents can be freely expressed with a small number of light emitting elements. The solar cell (SE) used in the present invention converts solar energy received from the sun into electromotive force, which prevents power loss and also has a large amount of trouble. Use a solar cell that can be used as. In addition, the storage battery B accumulates electromotive force from the solar cell SE, and serves to send electromotive force to the oscillation unit C according to the signal of the solar detection control unit A, and the backflow prevention diode D is a storage battery. (B) serves to send the electromotive force. The tandem light detecting control unit (A) detects the ambient illumination (ambient brightness) and judges day and night and controls the circuit to operate with a constant signal when it is dark, and the oscillator (C) has a flashing circuit It serves to blink and the amplification unit (Q) serves to amplify the oscillation signal even more. In addition, the light emitting unit L is composed of a plurality of high-brightness red light emitting elements (light emitting LEDs having a brightness of 8000 to 20,000 mcd) for easy identification, and emits strong light, and the optical fiber PC is formed of the light emitting unit L. It serves to deliver the flashing light to the sign (F), the sign (F) serves to deliver a message to the driver or people according to the purpose and purpose of the flashing light transmitted from the optical fiber (PC). FIG. 2 is a detailed circuit diagram of an embodiment, where SE is a solar cell, D is a backflow prevention diode, A is a solar detection control unit, B is a storage battery, SB is a spare battery, C is an oscillation unit, and Q is an amplification unit. , L is light emitting part, PC is fiber optic, F is sign, RI is current limiting resistor, R2 is resistor, R3 is bias resistor, R4 is current limit resistor, R5 is bias resistor, R6 VR is variable resistor, Q1 is transistor, C1 is a bias capacitor, C2 is a capacitor, CV is a voltage regulating terminal, IC is an oscillating IC, FQ is a FET transistor (FET-field effect), and TG is a trigger terminal. On the other hand, solar cell (SC) that receives sunlight incident during the day and converts it into electromotive force, storage battery (B) that charges the electromotive force generated from the solar cell and supplies it to the circuit and the light emitting element, and the electromotive force of the storage battery flows back to the solar cell The reverse current prevention diode D is connected. On the other hand, when the solar light is not incident for a long time, such as the rainy season, the battery (B) is completely dust-proof, the operation of the meeting can be stopped, so the spare battery (SB) in parallel to the battery (B) in parallel to the rainy season It can work smoothly even in the rainy season. When the peripheral road (ambient brightness) is detected and darkened, the oscillator L is connected to the output of the solar detection control unit A, which operates the circuit to make the light emitter blink, through the current limiting resistor RI. The oscillation section connects the base of the switching transistor Q1 to the current limiting resistor RI, the bias resistor R3 to the collector of the transistor Q1, and the operating power supply to the editor of the transistor Q1. In addition, a variable resistor (VR), a pull-up resistor (R2), and a bias capacitor (for connecting the reset terminal of the oscillation IC to the collector of the transistor Q1 and varying the oscillation period to the trigger terminal TG of the oscillation IC) C1 capacitor), the capacitor resistor C2 is connected to the voltage adjusting terminal CV of the oscillation IC, and the residual limiting resistor R4 and the bias resistor R5 are connected to the output terminal Q of the oscillation IC. The high efficiency FET (field effect) transistor FQ is connected to the residual limiting resistor R4, and the light emitting portion L is connected to the output of the FET transistor FQ. The light emitting part is connected to a plurality of LEDs of red high brightness (8,000 ~ 20,000mcd), which can be easily identified from a distance of 2Km ~ 3Km, and the blinking light from the LED is connected by optical fiber to secure the driver's watch. Give it. The solar light detecting control unit (A), which is composed of an illuminance switch, uses only the voltage difference generated when light is incident to enable charging only by not operating the lighting circuit during the day when there is photovoltaic power, and at night without photovoltaic power. By operating the lighting circuit using the charged power, it is possible to control the charging state and the lighting state. The lighting circuit unit C enables the transistor TR to control the operation of the unstable multivibrator by the solar detection control unit and receive the impossible signal. That is, during the day, when the output of the solar detector A is "H", since the switching transistor Q1 is turned on, the oscillation of the oscillation IC is stopped. When the output of the solar detector A is "L" at night, Since the switching transistor is turned off, the oscillation IC is reset and oscillates. The oscillation signal is inputted to the field effect transistor (FQ) and amplified by a signal of greater power, and emits a high brightness light emitting device, and the flashing light generated at this time is transmitted to the sign F through the optical fiber without attenuation, so 2Km-3Km By clearly delivering the contents of the sign to the driver at a long distance, it is possible to instill awareness in rainy weather and at night driving, thereby significantly reducing traffic accidents. In the present invention, the variable resistance (VR), resistance (R2), cone The oscillation period of a certain width and period is determined by the specified number of the tensors C1. When the transistor TR stops, the oscillation is automatically started by the reset terminal. A 50% duty wave is oscillated in the oscillation IC while adjusting the voltage and current, and the ON / OFF is determined by the duty ratio to continuously blink. 3 and 4 is a circuit configuration diagram of the central control unit (CPU) associated with the circuit of the present invention to precisely control each part of the circuit and numerical input (data) is possible according to the user's purpose of use. (B) When the voltage continues to rise during charging, a temporary voltage drop occurs at 2.9 V (full charge) (charging stops at the capture point when falling down). Battery B breakdown occurs, and the battery B operates normally at 2.1V. In addition, the proper capacity of the LED can be supplied from the CPU, that is, constant voltage and current can be supplied, and the maintenance of the lighting voltage is turned on when the solar voltage is 1V or less, and is turned off when it is 1.1V or more. Meanwhile, an optical fiber or an optical cable, which is an element of the present invention, transmits incident light efficiently to a desired destination while repeating total reflection or zigzag, as is well known, and a flexible fiber is bent. Even though there is a characteristic that the light goes through the fiber without loss. In addition, the optical sign 2 of the present invention using an optical fiber or an optical cable has a light source array 6 in which one or more light sources 4 are installed as shown in FIG. 3, and a light source fixture 8 in which the light source array 6 is fixed. And a binding ring 12 for coupling the plurality of strands 10a of the optical fiber 10 into one bundle, and a holder 14 for coupling the light source 4 and the binding ring 12 to face each other. The light emitted from the light source 4 is fixed to the cover patterns 18 of the various signs 16 by fixing the ends of the optical fiber 10 at appropriate intervals to the cover patterns 18 such as various letters, figures, and numbers. It is configured to be transmitted to the optical fiber cut surface 10b protruded out of the sign 16 by being fitted to the () part.

Although the light source 4 uses a high-performance light emitting diode having a high luminance of 8,000 to 20,000 candelas (mcd) and the like despite the low power consumption of several tens of mA to hundreds of mA, the cover pattern 18 has sufficient brightness (brightness). To emit light.

On the bottom surface of the holder 14 to which the light source 4 and the binding ring 12 are coupled. Forming a protrusion 20 protruding to the rear side to be firmly fixed to the specific portion of the label 16 or a separate support means with an adhesive, the light source 4 is coupled to both sides of the body portion of the holder 14 The insertion hole 22 and the binding ring 12 to form an insertion hole 24 is coupled to each.

The insertion holes 22 and 24 are formed with a stepped portion 26 as shown in FIG. 6 so that the binding ring 12 and the insertion hole 24 form a larger inner diameter than the light source 4 insertion hole 22 and bind. Preventing excessive insertion of the ring 12 and blocking light due to the thickness of the binding ring 12 is prevented.

7 is a cross-sectional view of another embodiment of the insertion hole 24a of the present invention. In the case where the number of optical fibers 10 is large or the outer diameter of the binding ring 12 is large while the outer diameter of the light source 4 is small, the binding ring insertion hole ( A light source insertion hole 22a having an enlarged inclined surface 28 in the 24) direction is formed to extend the number of uses of the optical fiber 10 or the unit size of the optical fiber.

In the present invention, the light source 4 and the insertion holes 22, 24, and 24a installed in the light source array 6 are illustrated in six, but the number of the light sources 4 and the insertion holes 22, 24, and 24a is greater than or equal to each other depending on the expression capacity or the luminous power. It can be formed and of course only one can be installed.

In addition, the upper part of the insertion hole 24 of the holder is formed by coupling the binding ring 12, which is formed by forming a piece hole 30, respectively, with a piece 32 to process the flow, separation and separation of the binding ring 12. The screw holes 34 are formed on both sides of the holders 14 and 14a, and through holes 36 are formed on both sides of the light source fixture 8, and the pieces 38 are used to form the light source fixture 8 and the holder. (14) (14a) to be fixed.

Meanwhile, as shown in FIGS. 3 and 4, the light source array 6 sandwiches a plurality of light sources 4 on the insulating substrate 40 at the same interval as the insertion hole 22, thereby providing two terminals 42 of the light source 4. Protruding the 44 to the rear surface of the insulating substrate 40 and then connecting them in parallel to the power supply lines 46 and 48 constitutes a light source fixture 8 in which a plurality of light sources 4 are simultaneously turned on or off. do.

The handle portion 50 protruding from the upper center portion of the light source fixture 8 separates the light source fixture 8 from the holders 4 and 4a. It is formed to be easy to grip when coupled, and reference numeral 54 is a space for wiring of the light source.

On the other hand, in the pattern (18) (18b) portion of the protective cap (10c) to protect the optical fiber 10, the hole 52 is formed at a predetermined interval to insert the protective cap (10c) and then the protective cap (10c) The end portion 10b of the optical fiber 10 is inserted into the central through hole to be fixed by an adhesive or the like, or to be fixed using a separate inserting or pressing means.

In the present invention, the number of protective caps 10c fitted into the holes 52 can be adjusted from 1 to 10 depending on the size of the cover patterns 18 and 18b and the illumination intensity required, and the number of optical fibers 10 In addition, dot light emission can be achieved in 10 or more if necessary.

In addition, the optical fiber cut surface 10b is inserted into the protective cap 10c protruding outwardly from the cover patterns 18 and 18b as shown in FIG. 5 so that the protective cap 10c protects the end of the optical fiber 10. (4) has no effect, so there is nothing wrong with the transmission of light.

In the present invention, the distal end 10b of the optical fiber 10 as shown in FIG. 8 is inserted into a protective cap 10c installed around the edge of the cover pattern 18 to cover the entire portion of the cover pattern 18b as shown in FIG. It is possible to increase the illuminance by densely installing at even intervals, and in some cases, lighting signs may be achieved by installing one or two lines at even intervals along the center line of the cover pattern.

In the present invention, the holders 14 and 14a may be made of a synthetic resin that is easy to mold, or may be made of a metal material such as light aluminum. The inner circumferential surfaces of the insertion holes 24 and 24a may be mirror-processed or board-shaped to reflect the reflectance. It is desirable to enhance or improve the reflectivity by applying a material having a good reflectance.

In addition, a lens 56 such as a concave lens, a convex lens, or a crown lens is inserted and installed between the incidence side cutting surface 10a of the optical fiber 10 and the light source 4, thereby increasing the light condensing ability and specially. It is possible to add an effect, and it is preferable to eliminate chromatic aberration using a crown lens, but in some cases, an illumination effect by chromatic aberration may be expected.

In the present invention, the light source 4 using the high-brightness light emitting diode or the like is satisfied when the driving power is 2V before and after, so when using a commercial AC power source (AC 220V) as shown in FIG. The power supply unit 58 to be supplied, the rectifying unit 60 for stepping down and rectifying the power supply to the driving power level before and after 2V required by the light source 4, and the light source 4 emitting light with high luminance by the rectified DC power supply 4 And the optical fiber 10 for transmitting the light of the light source 4 to the cover patterns 18 and 18b of the label 16.

In addition to the above, the labeling effect 18 or 18b is sequentially or non-sequentially flickered by providing a sequential or non-sequential blinking portion 62 between the light source 4 and the rectifying portion 60 to further increase the labeling effect. Can be promoted.

9 is a circuit block diagram that can be used for a mobile sign or a portable sign, a solar cell 64 for converting sunlight and ambient light into electromotive force, a control unit 66 having a charging unit and an illuminance switch function, and a solar cell ( Rechargeable battery 68 for charging the electromotive force generated from 64, the light source 4 emitting light with the storage power of the rechargeable battery 68, and the light emitted from the light source 4 to the cover pattern (18) (18b) It consists of an optical fiber 10 that transmits and displays without loss.

The solar cell 64 is installed on the upper surface of the label 16 that is the most incident of sunlight as shown in Figure 2, the control unit 66 with a charging circuit and the illumination switch is built in the case of the label 16 In this case, the holders 14 and 14a, to which the light source 4 and the optical fiber 10 are coupled, the rechargeable battery 68 and the on / off switch 70 may be installed at appropriate positions, respectively.

In the above daytime, the brightness is changed according to the ambient brightness of charge generated by the solar cell 64. That is, when the surroundings of the solar cell 64 are bright, a large amount of charges are generated to increase the electromotive force. On the contrary, when the surroundings of the solar cell 64 are dark, a small amount of electric charge is generated and the output electromotive force is lowered. Therefore, in the present invention to utilize the advantage as an illuminance switch.

That is, in the control unit 66 having the charging device, the ambient brightness of the label 16 is darkened below a certain level so that the electromotive force (or electromotive current) of the solar cell 64 at the point where illumination is required is referred to as the reference voltage (or reference current). Although the reference electromotive force (or electromotive current) input from the solar cell 64 and the reference voltage (or reference current) set in the controller 66 are compared, the input electromotive force (or electromotive current) becomes the reference voltage (or reference current). If less than), it is possible to achieve the automatic illumination according to the ambient brightness of the label 16 by allowing the power storage of the storage battery 68 is supplied to the light source (4).

In the present invention, the light emitting diode used as an example of the light source 4 may use a single color light emitting diode or a multicolor light emitting diode to express the cover patterns 18 and 18b in various colors.

In addition, by providing a flashing portion 72 of the sequential or non-sequential manner between the light source 4 and the control unit 66 so that the cover patterns 18, 18b blink sequentially or out of sequence to further enhance the labeling effect. Can be.

Of course, in the present invention, a combination of FIGS. 8 and 9 may be used by a commercial AC power supply (AC 220V) and a solar cell 64.

The cover patterns such as figures and numbers are illuminated in various colors in a single color or in various colors, thereby improving the monotony of existing neon signs or various signs and at a high cost. Compared to the conventional neon signs or various signs having low efficiency lighting means, a large sign recognition effect can be obtained with less power consumption.

In addition, since the end portion of the optical fiber connected to the light source is installed directly on the cover pattern, there is no fear that the light source may be damaged from an external impact, and the life is semi-permanent. In addition, since it uses low power and uses an optical fiber (or an optical cable), there is no fear of electric leakage or electric shock even in high humidity or rain, and it can be used in a humid environment. In addition, in the case of a fluorescent lamp (or a light bulb) or a neon lamp, if it is broken, it immediately leads to failure, but since the bottom of the optical fiber, which is a light emitting part, is separated from the light source, even if the end of the optical fiber is damaged, there is no effect of causing any abnormality in the light transmission. In addition, the fluorescent lamp (or light bulb) has a predetermined lifetime and is weak against impact, but the light source according to the present invention is strong in impact and semi-permanent because the semiconductor light emitting part is molded and is not exposed to the outside. In addition, in the case of a portable or mobile, the solar cell and the power storage means and the illuminance switch are provided so that they can be used at night or in an area without electricity, and the energy saving and efficient use can be expected. In addition, since light is transmitted only to the necessary portion of the optical fiber, there is almost no loss of light, thereby having a high performance and excellent energy efficiency. In addition, it can be used in areas without electricity, unmanned areas, etc., it is a useful invention that is not only simple in configuration but also effective in light weight and volume.
