FIG. 1 shows a front view (with a lens and a reflector removed) and a top sectional view of a bicycle lamp. Also,
FIG. 2 shows a front view (a state in which a lens and a reflecting mirror are removed) and a side sectional view of the lamp. FIG. 3 is a front view and a side view of the lamp.

In the figure, a socket holder 8 is inserted into a head case 1 having a side lens 2 fitted on its side surface and fixed with screws or the like. In the socket holder 8, the main light bulb 6 and the sub light bulb 7 are connected to the lamp sockets 6a, 7a.
And a spare bulb storage portion 11 are provided. A control board 9 to which an optical sensor 10 is attached is fixed to the rear portion of the socket holder 8.
Lamp sockets 6a of the main light bulb 6 and the sub light bulb 7,
A dynamo cord 12 and a battery case cord 13 are pulled out from 7a via lead plates 6b and 7b, respectively.

On the front surface of the socket holder 8, the reflecting mirror 5 having the light leakage hole 5a on the side surface is placed, and then the front lens 3 is fitted into the front opening of the head case 1. A reflex reflector (RR) 4 is welded and fixed to the center position of the front lens 3 so that light from the front can be reflected.

Here, the mounting positional relationship between the main light bulb 6 and the sub light bulb 7 is a main feature of the present invention. However, no matter which of the main light bulb and the sub light bulb is turned on, the front irradiation is of course performed. That is, the light leak hole 5a of the reflecting mirror 5 with the light leak hole
Then, the light of the bulb is leaked to the outside through the side lens 2 fixed to the side surface of the head case 1 of the lighting device, and the light of both the main bulb 6 and the sub bulb 7 can be surely irradiated to the side. The main light bulb 6 and the sub light bulb 7 are installed.

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

FIG. 4 shows how the lamp and the battery power source are attached to the front hawk of the 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 mounting screws, washers, and hexagon nuts are attached. After fastening with, the cover 19 covers.

Thereafter, the dynamo cord 12 is used as the dynamo output terminal, and the battery case cord 13 is used as the battery case 1.
5 cord terminals are connected to each other. As shown in FIG. 5, the battery case 15 is composed of a battery case body, 15a, and a battery case lid 15b, and two AA batteries are mounted therein. The operation of the two-lamp type automatic lighting device for a bicycle constructed as described above is as follows.

In the case of a general tilting dynamo, the turning-on / off operation is started by pressing the dynamo into contact with the tire of the bicycle by manual operation, and in the case of a hub dynamo, the dynamo always rotates. However, the light sensor 10 detects the brightness, which causes the hub dynamo to start outputting and the main light bulb 6 to be turned on.

Further, the brightness is detected by the optical sensor 10, the rotation of the wheels is detected, and the sub light bulb is lit for a certain period of time by the battery power source after the vehicle is stopped when the vehicle needs to be lit and when the bicycle is running at a slow speed. It constitutes an automatic lighting device. By using a nickel sphere having a good light-collecting property for the sub-bulb 7, it is possible to secure a front view without a reflecting mirror.

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

Thus, by installing the sub-bulb 7 at a position where light can be emitted, it is possible to emit light to the front and the side during low-speed traveling requiring lighting, after stopping during traveling requiring lighting, or during low-speed traveling. Therefore, the visibility from the front and the sides can be improved. Further, since the reflex reflector (RR) 4 is welded and fixed to the front lens 3, the light from the front can be reflected and the visibility can be further improved.

Next, the operation of the control circuit shown in FIG. 6 will be described by taking as an example a two-lamp type automatic lighting device for a bicycle of a type equipped with a hub dynamo and a battery power source. 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 the control circuit.

The main bulb 6 has a large resistance value when the optical sensor CdS is dark and a small resistance value when the light sensor CdS is bright, so that the negative input of the comparator IC1 is L when it is bright.
(Low), it becomes H (high) when it is dark, and the output of the comparator becomes H when it is bright and L when it is dark. Therefore, the transistor Q2 turns on only when driving in the dark.
Then, a current flows through the phototriac coupler IC2, the triac TR is turned on, and the main bulb 6 is turned on by the power source of the dynamo Dy. And the main bulb 6
Can illuminate the front and pass through the side lens to emit light in the lateral direction. The sub light bulb 7 is lit by the battery power source B only at low speed in darkness or after stopping,
It is set to turn off when driving at high speed.

First, when the vehicle is running when it is bright, the output of the comparator IC1 becomes H, and the transistors Q4 and Q5 are O.
Since it is FF, the transistor Q6 for driving the sub light bulb is turned off, and the sub light bulb 7 is not turned on.

During high speed running in darkness, the hub dynamo power supply voltage is detected by resistors R10 and R11, and the base potential of the transistor Q3 is H at high speed and L at low speed.
Since the base potential of the transistor Q3 is H at high speed, the transistor Q3 is turned on. As a result, the base potential of the transistor Q4 becomes L, the transistors Q4 and Q5 are turned off, and the sub bulb is not turned on.

When driving at low speed in the dark, the transistor Q3
Since the base potential of the transistor becomes L, the transistor Q3 becomes O
It becomes FF. D3, D2, R from constant voltage circuit by running
Since the base potential of the transistor Q4 becomes H via H and the transistor Q4 becomes ON, the base potential of the transistor Q5 becomes L and the transistor Q5 turns 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 light bulb 7 is turned on by the battery power source B. And the light of the sub-bulb 7
Together with the light from the main bulb 6, it is possible to illuminate the front and also to emit light in the lateral direction through the side lens. At this time, the capacitor C3 is simultaneously charged. 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 charge stored in the capacitor C3 even when the bicycle is stopped.

Even at low speeds, the output of the hub dynamo is low and the base potential of the transistor Q4 is L and the transistor Q4 is OFF, so the base potential of the transistor Q5 is H and the transistor Q5 is OFF. ,
Due to the discharge of the electric charge stored in the capacitor C3 until then, the transistor Q6 is turned on for a certain time, and the sub light bulb 7
Keeps lighting for a certain period of time. Therefore, the main light bulb and the sub light bulb do not light up when the vehicle is running in a bright state.

During high speed running in the dark, the main light bulb 6 is turned on, the sub light bulb 7 is not turned on, and during low speed running in the dark,
The main bulb and the sub bulb are lit. In addition, the sub bulb 7 continues to light for a certain period of time when the vehicle is running at a slow speed in the dark or when the bicycle is stopped.

In the above description of the circuit, an example in which the main light bulb is turned on by the output power of the hub dynamo has been shown, but the same applies to not only the hub dynamo but also a general tilting dynamo. . In that case, lighting of the main light bulb is started by pushing down the dynamo and pressingly contacting the tire with the action of a person, but the function of the sensor for detecting the brightness can be used together with the speed detecting means. By having a sensor that detects the brightness, the sub bulb can be turned on when it is bright, and unnecessary consumption of battery power can be prevented.

Further, as the speed detecting means, the electromotive force of the dynamo is used in the above embodiment, but as another means, for example, the speed is detected by a combination of a magnet attached to the rotating part and a reed switch. You may do it.

[0031]

As described above, the two-lamp type automatic lighting system for a bicycle according to the present invention has the above-mentioned configuration, in which the main light bulb is lit by the dynamo or the hub dynamo when the vehicle is required to be lit and is required when the vehicle is lit at a low speed. Lighting The sub-bulb is lit for a certain period of time after the vehicle has stopped during running or when the bicycle is running at a slow speed, and the frontal irradiation is performed regardless of whether the main bulb or sub-bulb is lit, regardless of the positional relationship between the main bulb and the sub-bulb. Of course, through the light leak hole of the reflector with a light leak hole and the side lens fixed to the side surface of the head case of the lighting device, the light of the light bulb is leaked to the outside laterally, and the light of both the main light bulb and the sub light bulb is secured. By installing the main bulb and the sub-bulb in a position that can be laterally illuminated, not only the illumination of the front, but also during running and during a temporary stop such as waiting for a signal, 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, when the bicycle is traveling at a low speed while the vehicle needs to be lit, it is possible to compensate for the reduction in the irradiation light due to the reduction in the output of the dynamo. Further, even in a dark bicycle parking lot, the sub bulb is lit for a certain period of time, and the afterglow makes it easier to put in and take out the bicycle.
