Description

[Detailed Description of the Invention] Industrial Application Field This invention relates to a device for lighting auxiliary lights such as tail lights, side lights, parking lights, security lights, turn signals, and flasher signal lights on bicycles.

Prior Art Due to recent traffic conditions, for safety reasons, bicycles should also be equipped with auxiliary lights that can give clear signals in accordance with traffic rules. However, due to the nature of bicycles, an increase in driving effort should be avoided, and for economical reasons the power source is lightweight and small in capacity, making it impossible to run a large current and emit strong light, especially during the day. It did not work under sunlight. Therefore, an idea has been proposed that uses a xenon arc tube that emits strong light.

Problems the invention aims to solve Xenon arc tubes have long been known in terms of electrical circuits, but since they apply high voltage, they are dangerous to handle in devices that are subject to rainwater damage, such as bicycles, and are not suitable for practical use. It didn't turn out to be. This idea was made in view of this point.

Means to solve the problem Convert the low-voltage DC power supply to AC in the alternating voltage generator, convert it back to DC in the rectifier, and
A thyristor in the continuous blinking control section generates a pulse voltage at the required blinking interval, this pulse voltage is boosted by a trigger coil, and input to the xenon arc tube.
In a bicycle auxiliary light device that flashes a xenon luminous tube at a predetermined interval, the trigger coil and the xenon luminous tube are packed with insulating material, and are separately installed in the machine casing at the auxiliary light mounting point. The pulse voltage is supplied from the thyristor to the machine casing through the car body and a dedicated lead wire, and the lighting switch circuit is connected to the main electrode of the xenon arc tube on the car body ground side, and the pulse voltage is applied to the auxiliary light installation point inside the machine casing. This is an auxiliary bicycle light device that is characterized by emitting light by boosting the voltage.

Function By making the lighting time instantaneous, power consumption is reduced as much as possible to ensure economic efficiency. It is packed with insulating material and boosts the pulse voltage within the same machine casing, eliminating voltage drop loss and the risk of leakage. In addition, power is supplied from the power supply through the car body and a dedicated lead wire, and the switch circuit is made of Xenon. It is connected to the vehicle body ground side of the main electrode of the arc tube, ensuring double handling safety.

Embodiment Hereinafter, this invention will be explained with reference to drawings showing an embodiment of the invention. Reference numeral 1 denotes a power supply section, which is composed of a dry cell battery 2 and a main switch 3, which are mounted on the bicycle. Here, the dry battery 2 can be replaced by a rechargeable battery, a generator, or other power source.

4 is an alternating voltage generating section, which supplies the power of the power supply section 1 to a resistor R1, a transistor TR1, and a capacitor C.
1 and a transformer T generate an alternating voltage, and the secondary winding 5 of the transformer T generates an alternating voltage higher than the primary alternating voltage.

6 is a rectifier which converts the alternating voltage into direct current using a rectifier diode D1 and a rectifier capacitor C2;
And smooth.

7 is a continuous blinking control section, which is a Zener diode.
ZD, resistors R2 and R3, capacitor C3 and resistor R4 are connected as shown in the diagram, the blinking interval is set by the blinking interval adjusting resistor R3 and the simultaneous constant capacitor C3, a pulse voltage is generated, and this is applied to the gate of the thyristor SCR. Enter it and make it work,
Outputs pulse voltage at predetermined intervals. The output of this continuous blinking control unit 7 is connected to the bicycle auxiliary light mounting parts machine casings 11 and 12 through dedicated lead wires 8a and 8b, respectively.
9a, 9b and the vehicle body to supply pulse voltage and lighting current,
2, the pulse voltage is applied to the trigger coil TC1, respectively.
The xenon arc tube Xe1 in the light emitting section is boosted by TC2,
In addition to Xe2, it lights up momentarily.

ON-OFF switches SW2 and SW3 of the xenon arc tubes are connected between one of the main electrodes of the xenon arc tubes Xe1 and Xe2 and the vehicle body, and these are used as hand switches, and multiple safety lights and auxiliary lights such as signal lights are connected. The lights can be turned on and off simultaneously or individually.
Note that R5 is a resistor that limits the flow path current.

This invented auxiliary light device emits flashing light from a xenon arc tube, so it can be operated with a relatively small power supply installed on the bicycle, and the light emitted is instantaneous but powerful. It can fully perform various display and signal functions under sunlight during the day, and can therefore be equipped with auxiliary lights that are useful during the day.

In addition, a power generating section from a power supply section to a continuous blinking control section in the device is housed in one machine casing 10, and the machine casing 11 is installed at a desired position on a bicycle.
Since the 12 xenon light emitting tubes Xe1 and Xe2 are configured separately, even if the number of security lights and signal lights is increased or decreased depending on the type of bicycle or other circumstances, they can be used in common without changing the power generation section. It can be provided at low cost by taking advantage of mass production. In addition, since each trigger coil is installed in the machine casing to which the xenon arc tube is installed, the pulse voltage is boosted to a predetermined high voltage just before being applied to the xenon arc tube, shortening the high voltage electric circuit as much as possible. It is possible to reduce power loss, eliminate electric shock leakage, and make the xenon arc tube emit more powerful light. In addition, since the power generation section is housed in the machine case, and the machine case where each auxiliary light is attached is constructed separately, the xenon arc tube and trigger coil can be easily housed in an insulating material, such as a film package cage. It can be sealed, waterproof and insulated, and has the effect of preventing electric shock to the user in bicycles that are used daily and are exposed to rainwater. Furthermore, since a switch circuit is connected between one of the main poles of the xenon arc tubes installed at each location, which are grounded to the vehicle body, and the vehicle body, each switch circuit is low voltage, and the user There is no risk of being electrocuted and the switch can be operated safely.

Therefore, by equipping a bicycle with an auxiliary light that practically emits light under sunlight during the day, it contributes to traffic safety.

Incidentally, this device may be provided with an alarm generating circuit as shown in FIG. 2, for example, and in this embodiment, the alarm is generated in synchronization with the blinking operation of the auxiliary light. Therefore, route change signals, stop signals, etc. can be displayed in a double manner using light and sound, and the signals can be confirmed and transmitted to each other without error, thereby further improving traffic safety.
