Description

  The present invention relates to a bicycle lighting system for ensuring forward visibility from a bicycle user and ensuring visibility of a host vehicle by a vehicle approaching from the side.

  Conventionally, a bicycle is required to be equipped with a bicycle lamp on a front fork and a reflector on a wheel spoke. This is because if you drive with no light at night, you will not be able to see the front, and if you do not inform the bicycle or car that is approaching your vehicle from the side, you may have an accident. It is. Bicycle lamps are generally designed to light a bean bulb (incandescent bulb) and illuminate the light by reflecting it forward with a reflecting mirror, thereby ensuring forward visibility from the user of the bicycle. In order to ensure safety, we inform pedestrians in front of bicycles. Further, the reflecting plate reflects light such as a bicycle headlamp or an automobile headlight that is irradiated from the side to ensure visibility of the vehicle.

  By the way, to turn on the bicycle lamp, there is a method using electric power generated by rolling the dynamo with rotating wheel tires, and a method of turning on / off the power supply from the dry cell to the miniature bulb by operating the switch. Is mainly adopted. The lighting system using the dynamo requires a large amount of human energy to rotate the wheels, and requires about 50% more human power than when the dynamo is not driven to rotate. Therefore, it is a heavy burden especially for women and children, and it is often dangerous to travel without using a bicycle lamp even at night, which is dangerous for traffic safety. On the other hand, in the lighting system that supplies power to the miniature bulb from the dry battery, if the switch is turned on before driving at night, for example, the lamp remains lit while waiting for the signal at the intersection, and it is illuminated like a shopping street The lamp remains lit even when passing through a bright place where no battery is needed, which is uneconomical because dry batteries are consumed quickly.

  Therefore, as known in Patent Document 1 below, the present applicant can turn on the power switch before the bicycle runs at night, and the daylight switch can be used in a bright place such as a shopping street at night. The lamp is automatically turned off by the action, and when the vehicle stops temporarily such as waiting for a signal, it is turned on for a certain time after the stop, for example, for 10 seconds, and then the lamp is automatically turned off to make the battery more efficient. It proposes a dry battery light for bicycles that can be used well.

No. 7-19966

  However, problems to be solved still remain in the above-described bicycle dry battery lights. That is, the bicycle dry battery light can efficiently use the battery as described above, but the lamp that is turned on by power supply from the battery ensures forward visibility from the bicycle user. However, it does not even consider the function of the reflector attached to the wheel. Therefore, the reflector can inform the existence of the vehicle only to a bicycle or a car approaching from the side substantially perpendicular to the traveling direction of the vehicle, and when those vehicles are unlit. However, it cannot be said that it is sufficient in terms of ensuring nighttime traffic safety because the vehicle cannot be informed.

  Therefore, the present invention has been made in view of the above-described conventional problems, and while efficiently using a battery serving as a driving power source of a light bulb for ensuring forward visibility without incurring a complicated structure. An object of the present invention is to provide a bicycle lighting system having a configuration capable of notifying the side of the traveling direction to the side of the traveling direction by the light emitting means only when traveling at night.

  In order to achieve the above object, a bicycle lighting system according to a first aspect of the present invention includes a lighting unit that is disposed on a bicycle body and irradiates light forward in the traveling direction, and is attached to a wheel of the bicycle and emits light laterally. A side-visible light-emitting unit that irradiates, and the side-visible light-emitting unit includes a light source that irradiates light to the side, and a power source battery that powers and turns on the light source, A reed switch that closes each time it faces a magnet provided on the illumination unit in the middle of the power supply circuit from the battery to the light source, and an output when the vibration sensor provided on the side-viewed light emitting unit receives vibration. One of the switching means that is turned on is provided.

  In this bicycle lighting system, each time the wheel rotates once, the reed switch of the side-viewed light emitting part passes close to the magnet and closes the contact point. Each time it is closed, the lighting circuit of the light source is closed and the light source is turned on by being fed from the battery. For this reason, the side-viewed light-emitting unit detects the presence of the vehicle by self-light emission when a vehicle approaching the vehicle from the side is unlit or a pedestrian approaching from the side toward the vehicle. It can be surely notified, and the visibility from the side is greatly improved, which is extremely favorable for traffic safety. Also, the side-viewing light-emitting unit only turns on the light source for a short time for each rotation of the wheel only when traveling, so that the visibility from the side is effectively ensured by the blinking of the light source. However, the battery can be used efficiently. In addition, the said side view light-emitting part shall be equipped with the power switch. The combination of the vibration sensor and the switching means that is turned on by the output when the vibration sensor receives vibration also closes the lighting circuit of the light source, and the light source is powered from the battery and lights up.

  In the above, the illuminating unit further includes a light bulb that emits light forward in the traveling direction, a battery of a driving power source that supplies power to the light bulb, and a lighting control that controls lighting and extinguishing by power feeding from the battery of the bulb. A circuit and a light receiving unit that provides rotation information by receiving light for lighting control in the lighting control circuit unit every time it faces the light source on the side-viewed light emitting unit side. it can.

  In the above, the illuminating unit may further include an illuminance sensor, and the lighting control circuit may illuminate the light bulb when the surrounding area is equal to or lower than a predetermined illuminance and in a running state. In addition, the said illumination part shall be provided with the power switch in the electric power feeding circuit to a light bulb.

  According to the bicycle lighting system of the present invention, each time the wheel makes one rotation, the reed switch of the side-viewing light-emitting part passes close to the magnet and closes the contact point. Each time the switch closes the contact, the lighting circuit of the light source is closed, and the light source is powered from the battery and lights up. For this reason, the side-viewed light-emitting unit detects the presence of the vehicle by self-light emission when a vehicle approaching the vehicle from the side is unlit or a pedestrian approaching from the side toward the vehicle. It can be surely notified, and the visibility from the side is greatly improved, which is extremely favorable for traffic safety. Also, the side-viewing light-emitting unit only turns on the light source for a short time for each rotation of the wheel only when traveling, so that the visibility from the side is effectively ensured by the blinking of the light source. However, the battery can be used efficiently. The lighting circuit of the light source is closed, and the light source is turned on by being fed from the battery.

  Hereinafter, preferred embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing a bicycle 1 equipped with a bicycle lighting system according to a first reference example of the present invention. This bicycle illumination system includes a front illumination portion 3A attached to a front fork 2 constituting the main body of the bicycle 1 and a side cover attached to a front spoke 7 of a front wheel 4 and rotating integrally with the front wheel 4. A visibility member 8 is provided.

  FIG. 2 is a block diagram showing the electrical system of the bicycle lighting system. The front illumination unit 3A is configured to light a miniature light bulb 9 as an illumination light source with a battery 10 serving as a driving power source without using a power generation lamp. The lighting control circuit unit 11 of the miniature light bulb 9 includes a monostable circuit 12 and an amplifier circuit 13. The monostable circuit 12 is a monostable multivibrator that can be re-triggered in this embodiment, and can be configured using, for example, a C-MOS IC4528 or 4538, or another IC or transistor.

  The monostable circuit 12 controls lighting of the miniature light bulb 9 based on detection signals respectively output from a known daylight switch (illuminance sensor) 14 and a rotation detection sensor 20. The daylight switch 14 does not output a detection signal for operating the monostable circuit 12 when the received light illuminance is bright, for example, 50 Lx or more, and outputs an illuminance detection signal when the received light illuminance is dark, for example, 50 Lx or less. It functions to activate the monostable circuit 12.

  On the other hand, as shown in FIG. 1, the side visibility member 8 is made of an integrated body in which a magnet 18 is integrated with a reflecting plate 17, and is fixed to the front spoke 7 of the front wheel 4. On the other hand, the reed switch 19 that constitutes the rotation detection sensor 20 together with the magnet 18 is provided in the front illumination unit 3A in an arrangement so as to face the rotation trajectory of the magnet 18 when the front wheel 4 rotates. . The reed switch 19 and the magnet 18 constitute a non-contact type rotation detection sensor 20 that detects whether the bicycle 1 is running or stopped.

  Next, the operation of the bicycle lighting system will be described. When traveling at night, first, the power switch 21 of the front illumination unit 3A is turned on. When the bicycle 1 is run, the magnetic flux of the magnet 18 of the laterally visible member 8 crosses the reed switch 19 of the front illumination unit 3A every time the front wheel 4 makes one rotation. Are magnetized so that they are attracted to each other to close the contacts, and a pulse as a rotation detection signal is input from the reed switch 19 to the monostable circuit 12 each time. The monostable circuit 12 keeps the output at a high level when one or more of the next pulses are input within 10 seconds each time a pulse is input, and the output is at a high level for 10 seconds. The output changes to low level when 10 seconds have passed without the next pulse being input since the pulse was input.

  Therefore, when the bicycle 1 continues to run, the output of the monostable circuit 12 maintains a high level, the high level signal is amplified by the amplifier circuit 13, and the miniature light bulb 9 is turned on. When the light bulb 9 is turned on and enters a shopping district or the like, the operation of the monostable circuit 12 is stopped by the daylight switch 14 when the light receiving illuminance from the outside becomes 50Lx or more, Immediately the mini bulb 9 goes out. When the bicycle 1 is temporarily stopped in a relatively dark place such as waiting for a signal, the daylight switch 14 keeps the monostable circuit 12 in an operating state. The bean bulb 9 is turned on only during the period from when the pulse is input until 10 seconds have passed without the next pulse being input, and then the bean bulb 9 is automatically turned off.

  Therefore, in this bicycle lighting system, the side visible member 8 made of a single member in which the magnet 18 is integrated with the reflecting plate 17 is simply configured to be attached to the front wheel 4, but it travels in a dark place. The bean bulb 9 is automatically turned on only when necessary for a short period of time after a temporary stop, and automatically turned off when no longer needed, so the battery 10 is used very efficiently. be able to. In addition, the side visibility member 8 does not have a self-luminous function, but reflects the light of the headlamps and headlights of a car approaching from the side as in the prior art by the reflector 17. These vehicles can be informed of the existence of the vehicle.

  Since the bicycle lighting system includes the daylight switch 14, even if the power switch 21 is always turned on, the miniature light bulb 9 is not automatically turned on unless the received light illuminance becomes darker than 50Lx. Can be reliably prevented. However, in a parking lot or the like, it is preferable to turn off the power switch 21, thereby preventing the battery 10 from being consumed due to careless movement of the bicycle at night.

  FIG. 3 is a block diagram showing the electrical system of the bicycle lighting system according to the first embodiment of the present invention. In FIG. 3, the same or equivalent parts as those in FIG. The description is omitted, and only the configuration different from that in FIG. 2 will be described. In this bicycle lighting system, the magnet 18 is attached to the front illumination unit 3B and the reed switch 19 is attached to the side-viewed light emitting unit 22A, contrary to the arrangement of the rotation detection sensor 20 of the first embodiment. A first rotation detection sensor 25 is configured. Moreover, instead of the lateral visibility member 8 in the first embodiment, a laterally visible light emitting portion 22A is attached to the front spoke 7 of the front wheel 4.

  The side-visible light-emitting portion 22A is provided with light-emitting diodes 23 and 24 that self-emit visible light on both sides, and a lighting control circuit for both the diodes 23 and 24 is a battery of a driving power source. 27, an amplifier circuit 28, a power switch 29, and a reed switch 19 of the first rotation detection sensor 25. On the other hand, the second rotation detection sensor 26 for inputting a pulse to the monostable circuit 12 in the front illumination unit 3B every time the front wheel 4 makes one rotation by detecting the traveling state of the bicycle 1 includes two light emitting diodes. 23 and 24, the light emitting diode 24 that emits light toward the side-visible light emitting portion 22A side, and the photoelectric conversion disposed in the position and the direction in which the light emitted from the light emitting diode 24 can be received in the front illumination portion 3B. It is comprised with the element 30. FIG. Although the phototransistor is illustrated as the photoelectric conversion element 30 in this embodiment, any photoelectric conversion element 30 may be used as long as it can convert light such as a photocell or a photodiode into an electric signal.

  Next, the operation of the bicycle lighting system will be described. When traveling at night, the power switch 21 of the front illumination unit 3B and the power switch 29 of the side-viewed light-emitting unit 22A are turned on. When the bicycle 1 is run, every time the front wheel 4 makes one turn, the reed switch of the side-viewed light emitting portion 22A passes through the proximity position of the magnet 18 and the reed switch 19 crosses the magnetic flux of the magnet 18. Therefore, the pair of leads of the reed switch 19 closes the contacts. In the side-viewed light-emitting portion 22A, each time the reed switch 19 closes the contact point, the lighting control circuit for both the light-emitting diodes 23 and 24 is closed, and both the light-emitting diodes 23 and 24 are supplied with power from the battery 27 and are lit together. . That is, both the light emitting diodes 23 and 24 blink once per rotation of the front wheel 4.

  As described above, the side-viewed light-emitting portion 22A that is attached to the front wheel 4 and rotates together with the front-wheel 4 repeats the lighting of the light-emitting diodes 23 and 24 every time the front wheel 4 makes one rotation, and the two light-emitting diodes 23 and 24 are designed to irradiate light to different sides, so that when a vehicle approaching the vehicle from the side is unlit or a pedestrian approaching from the side toward the vehicle Unlike the passive reflector 17, the presence of the vehicle can be surely notified by self-light emission, and visibility from both sides is greatly improved, which is extremely favorable for traffic safety.

  Since the side-viewed light-emitting portion 22A only lights the light-emitting diodes 23 and 24 only for a short time for each rotation of the front wheel 4 only during traveling, the battery 27 can be used efficiently. For this reason, as the light source of the side-viewed light-emitting portion 22A, the power-saving light-emitting diodes 23 and 24 are used in this embodiment. It can be used for a relatively long time.

  Further, the light emission of one light emitting diode 24 in the side visually recognizable light emitting portion 22 </ b> A is received by the photoelectric conversion element 30 every rotation of the front wheel 4. Thereby, since a pulse is input to the monostable circuit 12 every rotation of the front wheel 4 from the photoelectric conversion element 30, the front illumination unit 3B is similar to the front illumination unit 3A in the first embodiment. Operate. That is, when the bicycle 1 continues to run, the output of the monostable circuit 12 is maintained at a high level and the light bulb 9 is turned on. The daylight switch 14 stops the operation of the monostable circuit 12 and the miniature light bulb 9 is immediately turned off. When the bicycle 1 is temporarily stopped in a relatively dark place, the bean bulb 9 is turned on only until 10 seconds elapse, and then the bean bulb 9 is automatically turned off. Therefore, the front illumination part 3B can use the battery 10 very efficiently by the simplified configuration using the self-light emission by the side-viewed light-emitting part 22A.

  FIG. 4 is a schematic plan view showing a bicycle lighting system according to a second embodiment of the present invention, partially cut away. In FIG. 5, the front illumination unit 3B having the same electrical system configuration as that of the second embodiment will be described in detail later with reference to FIG. 5, so only the members related to the side-viewed light-emitting unit 22B are illustrated. It is shown. That is, the front illumination unit 3B of FIG. 4 shows a state in which a case lid, which will be described later, is removed, and the reflecting mirror 33 is placed on the circuit board 32 disposed on the front side (lower side in the figure) inside the outer case 31. The light receiving part 34 including the above-mentioned photoelectric conversion element 30 is disposed and attached in such a direction as to receive light emitted from the light emitting diode 24 of the side visually recognized light emitting part 22B. A miniature light bulb 9 as a light source is disposed in the center of the reflecting mirror 33, and a lens cap 37 is fitted and fixed to the front portion of the reflecting mirror 33. Further, the magnet 18 is fixed to the vicinity of the light receiving unit 34 in an arrangement so as to be close to and opposed to the laterally visible light emitting unit 22B. Therefore, the front illumination unit 3B of the first embodiment whose electrical system is illustrated in FIG. 3 has the same configuration as described above.

  On the other hand, the outer case 38 of the laterally visible light emitting portion 22B has a structure in which a case main body 39 and a case lid 40 are combined in a watertight manner with a packing (not shown) interposed therebetween. In the outer case 38, the case main body 39 is fixed to the front spoke 7 on one side of the front wheel 4 in FIG. 1 by the mounting member 41, and the case lid 40 is separated from the case main body 39 by the adjustment screws 42 on both ends. It is urged in the direction and is pressed and fixed to the front spoke 7 on the other side.

  Inside the outer case 38, an iron core 43 around which a winding 44 is wound is fixed to the inner surface of the case lid 40 so as to be able to pass while approaching the magnet 18 of the front illumination unit 3B. In addition, two light emitting diodes 23 and 24 are attached to a circuit board 48 provided inside the outer case 38 in such a manner that light can be emitted toward different sides. The light emitting diodes 23 and 24 are individually provided. The diffusion cases 49 and 50 are covered. The case main body 39 and the case lid 40 are provided with light emission windows 51 and 52 at locations corresponding to the diffusion cases 49 and 50, respectively.

  FIG. 5 is an exploded perspective view showing the front illumination unit 3B. The outer case 31 shown in FIG. 4 is formed by a case main body 31a and a case lid 31b. FIG. 4 shows a state where the case lid 31b is removed. A battery lid 53 provided behind the outer case 31 is attached to the outer case 31 by a resin bolt 54. When replacing a battery (not shown) accommodated in the case main body 31a, the resin bolt 54 is replaced. Is performed by removing the battery lid 53.

  The lens cap 37 and the reflecting mirror 33 are attached to the front side of the outer case 31 by a detachable fitting structure, and the miniature light bulb 9 is fitted into the bulb receiver 57 held at the center position of the reflecting mirror 33. When 37 is pulled out from the outer case 31, the reflecting mirror 33 can be removed in addition to the lens cap 37, and the miniature light bulb 9 can be replaced in this state. Further, in the case main body 31a, a circuit board 32 constituting a control circuit, an oscillation circuit, and the like, and a board protection plate 58 for protecting the front of the circuit board 32 are provided, and a battery is relayed behind the circuit board 32. In addition, a light bulb spring 59 which is a power supply means to the miniature light bulb 9, an insulating plate 60 for fixing the light bulb receiver 57, the above-described daylight switch 14 which protects the built-in daylight switch 14, and the above-described magnet. 18 and a power switch 62 are disposed.

  FIG. 6 is a block diagram showing the electrical system of the bicycle lighting system of the second reference example. In the figure, the same or equivalent parts as those in FIGS. 1 to 5 are designated by the same reference numerals, and the description thereof is omitted. The front illumination unit 3B has the same electric circuit configuration as the front illumination unit 3B in the bicycle illumination system of the first embodiment shown in FIG. On the other hand, the lighting control circuit for the light-emitting diodes 23 and 24 in the side-viewed light-emitting portion 22B charges the winding 44 wound around the iron core 43, the backflow prevention diode 63, and the induced electromotive force generated in the winding 44. An electrolytic capacitor 64, a power switch 62, and a load resistor 68 are included. The magnet 18 of the front illumination unit 3B and the iron core 43 and the winding 44 of the side-viewed light emitting unit 22B constitute a power generation mechanism unit 35. The power generation mechanism unit 35 also serves as a rotation detection sensor. Further, the rotation detection sensor 26 is the same as the second rotation detection sensor 26 of FIG. 3, and is configured by the light emitting diode 24 of the side-viewed light emitting unit 22B and the photoelectric conversion element 30 of the front illumination unit 3B. Has been.

Next, the operation of this bicycle lighting system will be described. When traveling at night, the power switch 21 of the front illumination unit 3B and the power switch 62 of the side-viewed light emitting unit 22B are turned on. When the bicycle 1 is run, every time the front wheel 4 makes one turn, the iron core 43 of the side-viewed light emitting portion 22B and the winding 44 wound around the light pass through the proximity position of the magnet 18. Therefore, an induced electromotive force is generated in the winding 44 according to Faraday's law of electromagnetic induction. As shown in FIG. 7, the induced electromotive force E _O has a much higher voltage than the forward voltage V _F of the light emitting diodes 23 and 24, this voltage charges the electrolytic capacitor 64. The charged charge of the electrolytic capacitor 64 is discharged when the side-viewed light-emitting portion 22B moves away from the magnet 18 as the front wheel 4 rotates, and is supplied to both the light-emitting diodes 23 and 24 through the load resistor 68. The light emitting diodes 23 and 24 are automatically turned on. Light emitted from the light emitting diodes 23 and 24 is diffused by the diffusing cases 49 and 50 and irradiated to the surroundings.

  As described above, the side-viewed light-emitting portion 22B attached to the front wheel 4 and rotating integrally has the light-emitting diodes 23 and 24 at the timing of each rotation of the front wheel 4 as in the second embodiment. Since the lighting is repeated and the two light emitting diodes 23 and 24 are irradiated to different sides, unlike the passive reflector 17, the vehicle approaches the vehicle from the side without light. A pedestrian approaching from the vehicle or the side toward the vehicle can be surely informed of the presence of the vehicle by self-emission, and the light emitted from the light-emitting diodes 23 and 24 can be emitted by the diffusion cases 49 and 50. Since the diffuse irradiation is performed, the visibility of not only both sides of the vehicle but also almost the entire periphery is remarkably improved, which is extremely preferable for traffic safety.

  The side-viewed light-emitting portion 22B turns on the light-emitting diodes 23 and 24 by the generator action of the iron core 43, the winding 44, and the magnet 18, so that a battery as a driving power source is unnecessary and can be used economically over a long period of time. it can. In addition, the generator action is different from the conventional method in which the power is generated by the dynamo rolling by the front wheel, and the front wheel 4 in which the side-visible light-emitting portion 22B is simply fixed is rotated manually. Thus, energy conversion from a mechanical system to an electrical system is performed, and no large human energy is required to rotate the wheel as in the case of a dynamo. In this embodiment, the light-emitting diodes 23 and 24 of the side-viewed light-emitting portion 22B are turned on by the generator action. Therefore, even if the power switch 62 is always on, the battery as in the second embodiment However, it is preferable to turn on the power switch 62 only during night driving in order to prevent unnecessary lighting and extend the life of each member.

  Moreover, since the magnet 18, the iron core 43, the winding 44, and the like constituting the power generation mechanism unit 35 light the light-emitting diodes 23 and 24 with low power consumption, they are compared with a dynamo for lighting a conventional miniature light bulb. And the shape can be reduced. In actual measurement, when 3.0 V is applied to the light emitting diodes 23 and 24 to light them, the required effective magnetic flux of the magnet 18 is 715 (maxwell), and if the leakage magnetic flux is 30%, the magnetic flux of the magnet 18 1800 (maxwell) is required, but in the case of a dynamo of 6 W and 3 W, a magnetic flux of 4800 (maxwell) is required. Therefore, the magnet 18 having a size of about 1/4 compared to the above dynamo. The winding 44 whose number of turns is determined by a temporal change in the number of magnetic flux linkages may be about ½ the size of the dynamo. Further, if a magnet 18 having a large magnetic flux such as anisotropy is used, the winding 44 can be easily downsized to about 1/3 to 1/4 compared to the above dynamo. The outer case 31 to be accommodated can be reduced in size and can be attached to the front spoke 7 or the like without any trouble.

  Further, in the rotation detection sensor 26, the light emission of one light emitting diode 24 of the side visually recognized light emitting unit 22 </ b> B is received by the photoelectric conversion element 30 of the front illumination unit 3 </ b> B through the light receiving unit 34 every one rotation of the front wheel 4. Thereby, since a pulse is input to the monostable circuit 12 every rotation of the front wheel 4 from the photoelectric conversion element 30, the front illumination unit 3 </ b> B includes the front illumination unit 3 </ b> A in the first and second embodiments. Works as well.

  That is, when the bicycle 1 continues to run, the output of the monostable circuit 12 is maintained at a high level and the light bulb 9 is turned on. In such a case, the daylight switch 14 stops the operation of the monostable circuit 12 and the miniature light bulb 9 is immediately turned off. When the bicycle 1 is temporarily stopped in a relatively dark place, the bean bulb 9 is turned on only until 10 seconds elapse, and then the bean bulb 9 is automatically turned off. Therefore, also in this bicycle lighting system, the battery 10 of the front lighting unit 3B can be used very efficiently by the simplified configuration using the light emission of the light emitting diodes 23 and 24 of the side-viewed light emitting unit 22B.

  FIG. 8 is a block diagram showing an electrical system of a bicycle lighting system according to a third reference example of the present invention. In the figure, the same or equivalent parts as those in FIGS. 1 to 7 are designated by the same reference numerals and the description thereof is omitted. This bicycle illumination system is a modification of the bicycle illumination system of the second reference example, and differs from FIG. 6 in that the first embodiment shown in FIG. 2 is used instead of the rotation detection sensor 26 of FIG. As in the reference example, only the rotation detection sensor 20 including the magnet 18 of the side-viewed light-emitting portion 22C and the reed switch 19 of the front illumination portion 3C is provided.

  Therefore, in this bicycle lighting system, the power generation mechanism 35 detects the traveling of the bicycle, and the light emitting diodes 23 and 24 are automatically turned on by the induced electromotive force generated in the winding 44 of the power generation mechanism 35. Aside from the action of detecting the traveling of the bicycle by the power generation mechanism 35 and generating the light emitting diodes 23 and 24 by itself, the rotation detection sensor 20 is operated each time the front wheel 4 makes one rotation as the bicycle 1 travels. The magnetic flux of the magnet 18 of the side-viewing light emitting unit 22C crosses the reed switch 19 of the front illumination unit 3C, and the contact of the reed switch 19 is closed each time, and a pulse is input to the monostable circuit 12. The output of the monostable circuit 12 keeps the output at a high level as long as the bicycle 1 continues to run in a dark place and lights the bean bulb 9. The bean bulb 9 is turned on 10 seconds after the bicycle 1 stops. Is automatically turned off.

  In the bicycle lighting system of this embodiment, the same effect as that of the third embodiment can be obtained. In addition, when the rotation detection sensor 26 in the third embodiment is attached, the light emitting diode 24 emits light. There is an advantage that adjustment of optical axis alignment with the photoelectric conversion element 30 in the light receiving unit 34 is unnecessary.

  FIG. 9 is a block diagram showing an electrical system of a bicycle lighting system according to a fourth reference example of the present invention. In the figure, the same or equivalent parts as those in FIGS. 1 to 8 are designated by the same reference numerals, and the description thereof is omitted. The bicycle lighting system of this embodiment is different from the lighting system of FIG. 8 in that the lighting control circuit of the light emitting diodes 23 and 24 of the side-viewed light emitting unit 22D is used instead of the rotation detection sensor 20 of FIG. Only with a configuration in which a rotation detection transmission unit 69 including an interpolated wireless transmission unit 70 and a wireless reception unit 71 for outputting an operation pulse to the monostable circuit 12 of the front illumination unit 3D is provided. is there.

  In this bicycle lighting system, as in the lighting system of FIG. 8, the traveling of the bicycle 1 is detected by the power generation mechanism unit 35, and the electrolytic capacitor 64 is connected by the induced electromotive force generated in the winding 44 of the power generation mechanism unit 35. After charging, the light emitting diodes 23 and 24 are automatically turned on by the discharge charge of the electrolytic capacitor 64. The wireless transmission unit 70 inserted and connected to the lighting control circuit for the light emitting diodes 23 and 24 intermittently transmits a predetermined wireless signal that is supplied with power every time the light emitting diodes 23 and 24 are turned on. In the front illumination unit 3 </ b> D, a pulse is output to the monostable circuit 12 every time the wireless reception unit 71 receives a wireless signal from the wireless transmission unit 70. The output of the monostable circuit 12 keeps the output at a high level as long as the bicycle 1 continues to run in a dark place and lights the bean bulb 9, and after 10 seconds have elapsed since the bicycle stopped, Turn off automatically.

  In the bicycle lighting system of this reference example, in addition to obtaining the same effects as those of the second and third reference examples, the rotation detection transmission unit 69 transmits the rotation detection of the bicycle by transmitting and receiving radio signals. Since it is a structure, the radio | wireless transmission part 70 and the radio | wireless receiving part 71 can be attached, without aligning mutually. Therefore, in particular, the front illumination unit 3D having the wireless reception unit 71 has a greatly improved degree of freedom in its mounting position. For example, the front illumination unit 3D can be attached to a front basket to improve fashionability, or can be attached to a steering wheel while traveling. The power switch 21 can be easily operated. Furthermore, the same configuration as the front illumination unit 3D can be used as a backlight device for a tail lamp or a speedometer.

  In the third and fourth reference examples, the light emitting diodes 23 and 24 are illustrated as being lit by the induced electromotive force generated by the power generation mechanism unit 35 that also serves as the rotation detection sensor of the front wheel 4. Instead of the unit 35, the same rotation detection sensor 25 as shown in FIG. 3 may be used to detect the rotation of the front wheel 4, that is, the travel of the bicycle 1, and supply power from the battery 27 to the light emitting diodes 23 and 24. Good.

  FIG. 10 is a block diagram showing a bicycle lighting system according to the second embodiment of the present invention. In the figure, the same or equivalent parts as those in FIGS. 1 to 9 are denoted by the same reference numerals, and the description thereof is omitted. This bicycle lighting system is a modification of the bicycle lighting system according to the first embodiment shown in FIG. 3, and is different from the configuration shown in FIG. 3 in that a rotation including a magnet 18 and a reed switch 19 shown in FIG. In place of the detection sensor 25, a vibration sensor 72 that detects that the bicycle 1 is in a running state based on the vibration of the front wheel 4 is provided in the side-viewed light-emitting portion 22E, and the battery 27 in the side-viewed light-emitting portion 22E. The switching control means 73 that is turned on in response to the detection signal from the vibration sensor 72 is inserted and connected to the lighting control circuit of the light emitting diodes 23 and 24 that are lit by the power supply, and the magnet 18 is omitted from the front illumination unit 3E. is there. The vibration sensor 72 may be any sensor that can detect the vibration associated with the rotation of the front wheel 4. For example, a sensor having a structure in which a coil is displaced by vibration in a uniform magnetic field having a concentric circular gap is used. Can do.

  Therefore, in this bicycle lighting system, when the bicycle is run, the vibration sensor 72 detects the rotation of the front wheel 4 and turns on the switching means 73, whereby the lighting control circuits of the light emitting diodes 23 and 24 are closed. The light emitting diodes 23 and 24 are powered by the battery 27 and are lit. On the other hand, in the front illumination unit 3E, the photoelectric conversion element 30 of the rotation detection sensor 26 receives the light emitted from the light emitting diode 24 and outputs a pulse to the monostable circuit 12, so that the output of the monostable circuit 12 is dark. When driving, the level is always high, and the light bulb 9 is automatically turned on.

  In this embodiment, only when the bicycle 1 is traveling, the light-emitting diodes 23 and 24 of the side-viewed light-emitting portion 22E and the miniature light bulb 9 of the front illumination portion 3E are both fed from the individual batteries 10 and 27 and automatically. Since it is not necessary to provide the magnet 18 in the front illumination unit 3E as compared with the second embodiment, the front illumination unit 3E and the side-visible light emitting unit 22E are There is an advantage that the photoelectric conversion element 30 and the light emitting diode 24 can be attached in a relative positional relationship that is just aligned.

  While efficiently using the battery that is the driving power source of the light bulb to ensure forward visibility without complicating the structure, the light emitting means can be used to drive the vehicle sideways with respect to the driving direction only during night driving. It can inform the existence.
