J6 / 02). However, Japanese Patent Application Laid-Open
The device described in Japanese Patent Publication No. 77774 is a single lamp type and does not have a side reflection function. For this reason, the main light bulb is used after the vehicle is stopped for the required lighting and when the bicycle is slightly moved by the battery power source for a certain period of time, so that the load on the battery power source is large and the battery is significantly consumed. In addition, since it does not have a side reflection function, it can irradiate only the front, but the visibility from the side of the bicycle is poor and the alertness to pedestrians or other vehicles is low,
There was a problem in driving safety.

The vehicle disclosed in Japanese Utility Model Publication No. 4-54069 is a one-light type, although it has a side reflection function, and is not a type that uses both a dynamo and a power battery. It does not have a function to turn on for a certain period of time after stopping, so it was not possible to maintain the alertness to pedestrians or other vehicles even during pauses such as waiting for traffic lights, and bicycles because there is no afterglow even in dark bicycle parking lots There was inconvenience in putting in and out. Similarly, when the bicycle is running at a low speed, there is a problem that the forward irradiation is not sufficient due to a decrease in the output of the dynamo.

[0005]

SUMMARY OF THE INVENTION The present invention has been made in order to solve the above-mentioned problems, and uses a bicycle dynamo and a power battery together or a hub dynamo having a generator built in a bicycle hub and a power battery. The main light bulb is turned on by a dynamo or a hub dynamo when driving is required, and the sub-bulb is turned on by the battery power supply when driving at low speed. Irrespective of which of the light bulbs is lit, the light is emitted forward through the light leak hole of the reflector with light leak hole and the side lens fixed to the side of the head case of the lighting device, as well as forward irradiating. , A two-light automatic lighting system for a bicycle with a main light bulb and a sub light bulb installed at a position where both the main light bulb and the sub light bulb can be illuminated sideways.

When the main bulb and the sub-bulb are lit, the lamp is illuminated forward, as well as the light leakage hole of the reflector with the light leakage hole and the side fixed to the side of the head case of the lighting device. By setting the main bulb and sub-bulb in a positional relationship that allows the light from the bulb to leak to the outside through the lens and ensure that both the main bulb and sub-bulb are illuminated laterally, the bicycle must be turned on. At low speeds, it compensates for the decrease in irradiation light due to the decrease in dynamo output, and can alert pedestrians or other vehicles even during pauses such as waiting for traffic lights. In addition, by providing a reliable side reflection function, it is possible to increase visibility to pedestrians or other vehicles by ensuring visibility from the side of the bicycle, as well as illuminating the front, and improve driving safety.

At the center position of the front lens 3, a reflex reflector (RR) 4 is welded and fixed so that light from the front can be reflected.

Here, the mounting positional relationship between the main bulb 6 and the sub-bulb 7 is also a main feature of the present invention. However, regardless of whether the main bulb or the sub-bulb is turned on, it is needless to say that forward irradiation is performed. The light leak hole 5a of the reflector 5 with the light leak hole

A main light bulb 6 and a sub light bulb 7 are provided.

The head case 1 of the lamp is fastened with rivets integrally with the lamp holder 14. The control board 9 includes a circuit for detecting the rotation of the wheel by a dynamo, an optical sensor 10 for detecting the brightness, and a circuit for controlling the turning on and off of the lamp by the optical sensor 10. Also,
The device of the present invention is provided with a battery power supply in addition to the dynamo.

FIG. 4 shows how a lamp and a battery power supply are attached to a front fork of a bicycle. In the figure, the mounting holes of the lamp holder 14 and the mounting bracket 18 of the battery case 15 are aligned with the mounting holes of the front fork welding bracket 17 fixed to the front fork 16 of the bicycle, and the mounting screws, washers, and hexagon nuts are provided. After fastening, the cover 19 is used.

Thereafter, the dynamo cord 12 is connected to the dynamo output terminal, and the battery case cord 13 is connected to the battery case 1.
5 are connected to the respective code terminals. As shown in FIG. 5, the battery case 15 includes a battery case main body, a battery case 15a, and a battery case cover 15b, and two AA batteries are mounted. The operation of the thus-configured two-light automatic lighting device for a bicycle is as follows.

In the turning on / off operation, when the vehicle needs to be turned on, the output is started by bringing the dynamo into contact with the bicycle tire by a manual operation in the case of a general falling dynamo, and the dynamo is always rotated in the case of the hub dynamo. However, the brightness is detected by the optical sensor 10, whereby the output of the hub dynamo is started, and the main bulb 6 is turned on.

Further, the brightness of the bicycle is detected by the optical sensor 10, the rotation of the wheels is detected, and the sub-bulb is turned on by the battery power supply for a certain period of time after stopping at the time of driving required and at a low speed of the bicycle. An automatic lighting device is configured. By using a nipple sphere having a good light-collecting property for the sub-bulb 7, a front view can be secured without a reflector.

According to the mounting positional relationship between the main bulb 6 and the sub-bulb 7 according to the present invention, the light of the main bulb 6 illuminates the front as shown by the solid line, and the main bulb 6 is made of transparent glass. Light from the bulb 6 is transmitted and the light leakage hole 5
Light can also be emitted from side a through the side lens 2 and in the lateral direction, thereby improving visibility. Also, the light from the sub-bulb 7 can illuminate the front similarly to the main bulb 6 and emit light to the side as shown by the broken line.

As described above, by arranging the sub-bulb 7 at a position where light can be emitted, light can be emitted to the front and side at the time of low-speed driving required, after stopping at the time of required driving, or at the time of low-speed driving. As a result, visibility from the front and side can be improved. Further, since the reflex reflector (RR) 4 is welded and fixed to the front lens 3, light from the front can be reflected, and visibility can be further improved.

Next, the operation of the control circuit shown in FIG. 6 will be described with reference to an example of a two-light type automatic lighting device for a bicycle of a type equipped with a hub dynamo and a battery power supply. Dy is a dynamo (in this case, a hub dynamo), D1 is a rectifying diode, C1 is a smoothing capacitor, and a resistor R1, a transistor Q1, and a Zener diode ZD1 constitute a constant voltage circuit for protecting a control circuit.

The resistance of the main light bulb 6 is high when the light sensor CdS is dark and low when the light sensor CdS is bright.
(Low), H (high) when dark, and the output of the comparator is H when bright and L when dark. Therefore, the transistor Q2 is ON only when the vehicle is traveling in darkness.
Then, a current flows through the phototriac coupler IC2, the triac TR is turned on, and the main light bulb 6 is turned on by the power supply of the dynamo Dy. And the main light bulb 6
Can illuminate the front and emit light in the lateral direction through the side lens. The sub-bulb 7 is turned on by the battery power source B only at low speed in dark or after stopping,
It is set to turn off when driving at high speed.

First, when the vehicle is running in a bright state, the output of the comparator IC1 becomes H, and the transistors Q4 and Q5 are turned off.
Because of the FF, the sub-bulb drive transistor Q6 is turned off and the sub-bulb 7 does not light.

In a high-speed running in the dark, the hub dynamo power supply voltage is detected by the resistors R10 and R11, and the base potential of the transistor Q3 is H at a high speed and L at a low speed.
Therefore, at a high speed, the base potential of the transistor Q3 is turned on because it is H. As a result, the base potential of the transistor Q4 becomes L, the transistors Q4 and Q5 are turned off, and the sub-bulb does not light.

When the vehicle is running at a low speed in the dark, the transistor Q3
Since the base potential of the transistor Q becomes L, the transistor Q3
It becomes FF. D3, D2, R from constant voltage circuit by running
7, the base potential of the transistor Q4 becomes H and the transistor Q4 is turned on. Therefore, the base potential of the transistor Q5 becomes L and the transistor Q5 is turned on. As a result, a current flows through the base of the transistor Q6 and the transistor Q6 is turned on, so that the sub-bulb 7 is turned on by the battery power supply B. And the light of sub-bulb 7
Along with the light from the main bulb 6, it is possible to illuminate the front and emit light in the lateral direction through the side lens. At this time, the capacitor C3 is charged at the same time. Since the capacitor C3 uses an electric double-layer capacitor, the transistor Q6 can be turned on for about 10 to 15 seconds by discharging the electric charge stored in the capacitor C3 even when the bicycle is stopped.

[0027] Even at a low speed, the output of the hub dynamo is low and the base potential of the transistor Q4 becomes L and the transistor Q4 is turned off. Therefore, the base potential of the transistor Q5 becomes H and the transistor Q5 is turned off. ,
The transistor Q6 is turned on for a certain time due to the release of the electric charge stored in the capacitor C3, and the sub-light bulb 7
Keeps lighting for a certain period of time. Therefore, the main bulb and the sub-bulb do not light up when the vehicle travels in a bright state.

In high-speed driving in darkness, the main light bulb 6 is turned on and the sub-bulb 7 is not turned on.
The main bulb and the sub-bulb light up. In addition, when traveling at a low speed in the dark and when the bicycle is stopped, the sub-bulb 7 continues to be lit for a certain period of time.

In the above description of the circuit, an example in which the main light bulb is lit by the output power of the hub dynamo is shown. However, the same can be said not only for the hub dynamo but also when a general upside down dynamo is applied. . In this case, the lighting of the main light bulb is started by defeating the dynamo by the action of a person and bringing the tire into pressure contact with the tire. However, the function of the sensor for detecting the brightness can be used together with the speed detecting means. By having the sensor for detecting the brightness, the sub-bulb is turned on when it is bright, so that unnecessary consumption of the battery power can be prevented.

Further, in the above embodiment, the electromotive force of the dynamo is used as the speed detecting means. However, as another means, the speed is detected by a combination of a magnet mounted on a rotating part and a reed switch. You may do so.

[0031]

As described above, the bicycle two-lamp automatic lighting apparatus of the present invention has the above-described configuration, and turns on the main light bulb by the dynamo or the hub dynamo at the time of driving required. The sub-bulb is lit for a certain period of time by the battery power after stopping at the time of running and when the bicycle is running at a low speed, and the forward relationship is irrespective of the positional relationship between the main bulb and the sub-bulb, regardless of whether the main or sub-bulb is lit. Needless to say, the light from the main bulb and the sub-bulb are leaked to the outside through the light leak hole of the reflector with light leak hole and the side lens fixed to the side of the head case of the lighting device. By installing the main bulb and sub-bulb in a position where it can be illuminated laterally, it is possible to illuminate not only forward, but also during running and during pauses such as waiting for traffic lights. To secure the visibility from the side of the rolling wheel enhance reminder force to pedestrians or other vehicles, it is possible to keep the running safety. Further, it is possible to compensate for a decrease in irradiation light due to a decrease in the output of the dynamo when the bicycle travels at a low speed when the vehicle needs to be turned on. Furthermore, even in a dark bicycle parking lot, the sub-bulb lights up for a certain period of time, so that the afterglow makes it easier to put the bicycle in and out.
