Description

[Detailed explanation of the idea]

(Field of Industrial Application) The present invention relates to the field of illumination devices that emit light randomly. (Prior Art) Conventionally, a flash discharge lamp device that sequentially shifts a plurality of flash discharge lamps to flash fluidly has been developed.
Known as number 38800. (Problems to be solved by the invention) However, the above-mentioned conventional technology is related to emergency guide lights, and is for guiding the line of sight in one direction. It was not intended to attract public attention or be used as a toy to enhance the entertainment effect. Further, if the intermittent signal generation circuit of the prior art is driven in a non-fluid manner with a delay, it is possible to randomly flash the light, but this requires a complicated intermittent signal generation circuit. (Means for solving the problem) The present invention was made in view of the above-mentioned circumstances, and consists of a plurality of light emitting circuits each having a main capacitor with different charging characteristics connected in parallel to a power supply circuit. The problem was solved by connecting the light emitting circuit and causing the light emitting circuit to emit light using a trigger signal that is continuously sent out. (Example) Hereinafter, the present invention will be explained using an example shown in the drawings. FIG. 1 is a circuit diagram showing an embodiment of the present invention. The power supply circuit 1 is composed of an AC/DC or DC/DC converter, a stacked battery, or the like, and has output ends of a positive bus 2 and a negative bus 3. Light emitting circuit 4
9 are connected in parallel to the power supply circuit 1 between the positive bus 2 and the negative bus 3. The trigger signal generation circuit 10 continuously sends a trigger signal to the trigger terminal of each light emitting circuit through an output line 11. FIG. 2 shows the light emitting circuit 4. FIG. The anode of the diode 12 is connected to the positive bus 2 and the cathode to the line 13. The anode of the flash discharge lamp 14 is wire 13
The cathode is connected to the negative bus 3, and the trigger electrode is connected to the secondary side of the trigger coil 15. A resistor 16 and a trigger capacitor 13 are connected between the wire 13 and the primary side of the trigger coil, the anode of the thyristor 18 is connected to the connection point between the resistor 16 and the trigger capacitor 17, the cathode is connected to the negative bus 3, and the gate is connected to the output. It is connected to line 11. A main capacitor 19 is connected between the line 13 and the negative bus 3. The light emitting circuit 5 and below have the same configuration as the light emitting circuit 4 except that main capacitors having larger capacitances are used in order. Next, the operation of the present invention will be explained. In FIG. 2, the main capacitor 1 of the light emitting circuit 4
9 is empty, the main capacitor is charged from the positive bus 2 via the diode 12. Main capacitor 1
When capacitor 9 is charged with enough charge to cause flash discharge lamp 14 to emit light, approximately the same voltage is applied to capacitor 1.
7 is also charged. At this time, when a positive pulse is sent from the trigger signal generation circuit 10, the thyristor 18 becomes conductive, and the charge in the trigger capacitor 17 flows to the primary coil of the trigger coil, inducing a high voltage in the secondary coil. , the flash discharge lamp 14 discharges and emits light, and the charge in the main capacitor 19 becomes empty. When the main capacitor 19 becomes empty, it will be charged again via the positive bus 2 and the diode 12. Now, convert the time required for the main capacitor of each light emitting circuit to be charged to a voltage capable of emitting light to the pulse period of the continuous pulse signal sent from the trigger signal generation circuit 10 and set it as shown in the table below. Then, the light emission timing of each of the light emitting circuits 4 to 9 becomes as shown in FIG.

【table】

[Table] That is, the light emitting circuit 4 emits light at the rising edge of the 3rd cycle of the trigger pulse, the light emitting circuit 5 emits light at the rising edge of the 4th cycle, and the light emitting circuits 4 and 6 emit light at the rising edge of the 5th cycle, completing the 6th cycle. The light emitting circuit 7 emits light at the rising edge of the eye, the light emitting circuits 4, 5, and 8 emit light at the rising edge of the 7th cycle, and the light emitting circuit 9 emits light at the rising edge of the 8th cycle. Hereinafter, as can be seen from FIG. 3, the light emission timings of the plurality of light emitting circuits are shifted, the light emitting circuits emit light at different light emission intervals, and the plurality of light emitting circuits emit light at random. (Effects of the Present Invention) As described above, it is possible to provide a random illumination device with a simple configuration.
