A bicycle headlight having a side reflection function is disclosed in Japanese Utility Model Publication No. 4-54069 (B62).
J6 / 02). However, the above-mentioned JP-A-5
The one described in Japanese Patent No. 1777774 is a one-lamp type and does not have a side reflection function. Therefore, since the main light bulb is used after the vehicle is stopped when the vehicle needs to be lit, and when the bicycle is slightly moved for a certain period of time when the bicycle is slightly moving, the load on the battery power source is large and the battery is significantly consumed. In addition, since it does not have a side-reflective function, it can illuminate 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.

Further, the one described in Japanese Utility Model Publication No. 4-54069 mentioned above is a one-lamp type although it has a side reflection function, and it is not a type that uses both a dynamo and a power supply battery, so it is necessary to drive with lighting. Since it does not have the function of turning on for a certain period of time after stopping, it was not possible to maintain the power of alerting pedestrians or other vehicles even during a temporary stop such as waiting for a signal, and there was no afterglow even in a dark bicycle parking lot. There was inconvenience to put in and take out Similarly, when the bicycle is traveling at a low speed, there is a problem that the front irradiation is not sufficient due to the output reduction of the dynamo.

Further, the main light bulb is turned on by the dynamo or the hub dynamo when the vehicle needs to be lit, and the sub-bulb is kept for a certain period of time by the battery power source when the vehicle is traveling at a low speed which requires the illumination, after stopping at the time when the vehicle requires the illumination, and when the bicycle is traveling at a slow speed. When the main bulb or the sub bulb is turned on, the front light is emitted as well as the light leak hole of the reflector with a light leak hole and the side fixed to the side surface of the head case of the lighting device. By installing the main bulb and the sub bulb in such a positional relationship that the bulb light is leaked to the outside through the lens and both the main bulb and the sub bulb can be surely radiated to the side, the bicycle when the vehicle needs to be lit When driving at a very low speed, it compensates for the decrease in illumination light due to the decrease in output of the dynamo, and can alert pedestrians or other vehicles even during a temporary stop such as waiting for a signal. In addition, by providing a reliable side reflection function, it is possible to secure visibility not only from the front of the vehicle but also from the side of the bicycle to increase the alertness to pedestrians and other vehicles and improve running safety. It is an object of the present invention to provide a two-light type automatic lighting device for a bicycle that can be maintained.

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.

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.

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.

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.

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.
