Abstract

PURPOSE:To make such a safety lamp or a signal lamp as being excellent in sightability mountable on a bicycle or the like, by feeding power to a xenon light emitting tube after boosting with a trigger coil and thereby letting the tube emit flashing light. CONSTITUTION:An alternating high tension voltage generating part 4 receives power out of a power source 3 such as a dry battery or the like, making a secondary winding 5 of a transformer T generate the alternating high tension voltage, and this voltage is converted into a high tension direct current with a reactifier diode D1 and rectifier condenser C2 and smoothed. Next, storage of electricity takes place with a condenser C3 of a continuous flashing control part 7, while pulse voltage at the intervals required is generated, and an electromotive current by means of a thyristor SCR is still more boosted with trigger coils TC1 and TC2 for supplementary lamp parts 11 and 12 whereby each of xenon light emitting tubes Xe1 and Xe2 is made to perform flashing radiation. With this constitution, watt consumption can be reduced as compared with an incandescent lamp in which a continuous rating current flows and, what is more, ample sightability is secured even in the daytime.

Description

[Detailed Description of the Invention] The purpose of the present invention is to provide a lighting device for safe security lights, signal lights, and other auxiliary lights with high visibility using a small-capacity power source such as a generator or a dry battery mounted on a bicycle. This was done as a.

In order to be clearly visible to pedestrians and cars under the sun during the day, bicycles need safety lights, such as parking lights and interior lights, as well as generators installed on Shinkei vehicles. , dry cell batteries, etc. have a small capacity due to driving labor and economy, and it is not possible to cause a large amount of current to flow through an incandescent miniature bulb to cause it to emit strong light.

This invented device attempts to make it more powerful by making it less harmful and more powerful.

Hereinafter, the present invention will be explained with reference to the drawings which are an example of implementation. Reference numeral 1 denotes a power supply unit, and power supply 2 is a generator in which a constant voltage DC power supply such as a dry cell battery is driven to generate electricity. If this is the case, since electricity will not be generated while the bicycle is stopped, a separate auxiliary power source will be provided and the bicycle will be configured to supply power for at least the required time.

4 is an alternating high voltage generator, which includes a resistor R1 and a capacitor C.
1. The transistor 1 and the transformer T are connected as shown in the figure.Here, by receiving power from the power supply 2, an alternating high voltage is generated between the secondary winding 5 of the transformer T and the vehicle body ground. 6 is a rectifier which converts the alternating high voltage into high voltage direct current using a rectifier diode D1 and a rectifier capacitor 02, and smoothes it.

7 is a continuous blinking control section, which is a Zener diode ZD.

Connect resistor R2, R3, capacitor C3, and resistance loss as shown in the diagram, store the high voltage DC in capacitor C3, generate pulse voltage at required intervals, and add this to the thyristor in the main circuit to generate starting current. Then, power is supplied to the auxiliary light section using one of the lead wires 8a, 8b, 9a, 9b, and in the auxiliary light section, the voltage is boosted by a trigger coil and the starting voltage is applied to the xenon arc tubes Xel and Xe2 to flash and emit light. . Power is supplied by connecting one of the main electrodes of each of the xenon arc tubes to the lead wires 8a, 9a and grounding the other to the vehicle body.

A handy switch is connected between one of the main electrodes of the xenon light emitting device (IXel, k2) and the grounded vehicle body, and by operating it, the xenon light emitting tubes Xel and Xe2 are turned on and off simultaneously or individually. Therefore, by setting the lighting interval as required, it is possible to significantly reduce power consumption, unlike the light emitted by incandescent miniature bulbs that constantly pass current, and the light emitted is powerful enough to be used for practical purposes during the day. can emit a signal.

It can be installed on vehicles, wheelchairs, and other vehicles, and can be used to drive safely.
