Abstract

A method for producing synchronous or/and simultaneous periodic light in light signal systems consisting of several flashers. Each one of the flashers has its own electronics unit, these units being connected in series in such manner that the first unit in the series controls the rest so that all flashers will flash simultaneously or consecutively from flasher to flasher in a running fashion.

Description

METHOD FOR PRODUCING SYNCHRONOUS OR/AND SIMULTANEOUS PERIODIC LIGHT IN LIGHT SIGNAL SYSTEMS, AND AN APPARATUS FOR IMPLEMENTING THE METHOD
The present invention relates to a method and apparatus for producing synchronous or/and simultaneous periodic light in light signal systems consisting of several flashers. A dis¬ advantage with known signal devices of this kind, in which the flashers are connected in series and produce a running light beam, is- that if a malfunction occurs in one of the flashers or if the battery of a flasher is exhausted, then the series circuit is broken and the whole signal system goes off. Also, if the flashers are connected to a common electronics and battery/accumulator unit, the whole signal system goes off if a malfunction occurs in the electronics unit or the battery/accumulator.
The object of the present invention is to eliminate the drawbacks mentioned and create a new method. The method of the invention is characterized in that each one of the flashers has its own electronics unit, these units being connected in series in such manner that the first unit in the series circuit thus formed controls the rest of the units so that all flashers will flash simultaneously or consecutively from flasher to flasher in a running fashion. If a fault arises or the battery/accumulator is exhausted in any one of the units, the other flashers will not be affected because each flasher has its own electronics. In this case the remaining flasher units connected in series constitute two separate light signal devices.
The invention also relates to a flasher designed for imple¬ menting the method, consisting of a battery/accumulator, an electronics unit and a lamp. The flasher of the invention is characterized in that the electronics unit contains a timing circuit which is activated without an external control impulse and functions independently, controlling the next flasher in the series. Consequently, a safe and reliable light signal system can be formed, which will continue working even if a malfunction occurs one of the series-connected flashers.
A preferred embodiment of the invention is characterized in that the accumulators of all the series-connected flashers can be recharged using a common charger connected to the same series. This makes it unnecessary to disconnect individual flashers or remove the batteries for charging.
In the following, the invention is described by the aid of an example with reference to the drawings attached, wherein:
Fig. 1 presents two light signal systems placed on a road.
Fig. 2 presents a light signal system arranged in the form of an arrow.
Fig. 3 shows a circuit diagram representing the electronics unit of a flasher.
Fig. 4 shows a number of flashers connected in series.
In Fig. 1 , the flashers in group 1 can be so connected that they flash simultaneously. The flashers in group 2 are so connected that they produce a running light with the flashes proceeding in the direction indicated by the arrows. The light signal system may also be arranged as shown in Fig. 2, in which the lights are running except for those in the last unit forming an arrow head, which flashes continuously. The circuit represented by the diagram in Fig. 3 consists of a daylight and battery monitoring cir¬ cuit 3, an oscillator 4, a pulse width modulator 5, a lamp 6 and a counter 7. The flashers are connected to each other in such manner that the input is at point 8, the output controlling the flashers in simultaneous flashing mode is at point 9, and the output controlling the flashers in synchronous consecutive flashing mode is at point 10. Since each flasher has its own electronics unit and its own battery/accumulator, it is possible to form a series of any desired number of flashers. The light signal apparatus of the invention is very reliable in operation expressly for the reason that it is able to continue operating even if a malfunction should occur in one of the units.
