Description

[Detailed Description of the Invention] The present invention relates to a flasher for advertising lighting, and more particularly to a photoelectric flashing device for advertising lighting that creates various flashing patterns by rotating a light-shielding disc.

Conventionally, devices for sequentially blinking the lamps of advertising lights have been used to mechanically open and close a large number of electrical contacts in sequence to make the lamps blink in various patterns. During use, contact failures tend to occur due to contact wear, discharge, etc., which has the disadvantage of causing trouble. In addition, the blinking pattern was a method in which the lamps of the advertising lights were blinked in sequence, and the blinking pattern could only be repeated at a constant rate, and the blinking pattern could not be changed freely.

In view of these drawbacks of the conventional devices, the present invention aims to provide a blinker for advertising lighting that does not cause contact failure due to contact wear or the like. Still another object of the present invention is to provide a flasher for advertising lighting in which the flashing pattern can be freely set and the flashing pattern can be changed at any time.

In order to achieve the above objectives, the inventor of the present invention has conducted extensive research and has completed a photoelectric flasher for advertising lighting that can generate any desired flashing pattern by combining a photoelectric switch and a light-shielding rotating disk. I came to the point.

That is, the gist of the present invention is to provide a circumferential portion or each concentric portion of a light-shielding rotary disk in which a pattern consisting of a light-transmitting portion and a light-shielding portion is applied to the circumferential portion of the disk or each concentric portion divided into concentric circles. Light sources and light receiving parts of a large number of photoelectric switches are arranged side by side in the radial direction and/or radial direction of the disc, and the light reaching the light receiving part from the light source is intermittently transmitted by the light shielding pattern of the light shielding rotary disc. A photoelectric flasher for advertising lighting, characterized in that the photoelectric switch is opened and closed by blocking light, and a large number of lamps of the advertising lighting flash sequentially or independently according to the output signal of the photoelectric switch. .

Next, embodiments of the present invention will be explained in more detail with reference to the drawings. Figure 1 shows an example of the lamp arrangement of the advertising lighting of the present invention, with lamps 1a, 1b, 1c.
... are photoelectric switches 2a, 2b, 2c, respectively.
Blinks when activated. FIGS. 2 and 3 show an example of a light-shielding rotary disk 3 used in the flasher of the present invention, which has a notch 4 around its periphery and is rotated around a motor shaft 6 by a motor 5. FIG. A large number of photoelectric switches 2 are installed around the light-shielding rotary disk 3.
a, 2b, 2c, . The reaching light 9 is intermittently blocked by the rotation of the light-shielding disk 3, and the photoelectric switch 2 is opened and closed by the optical signal received by the light-receiving element 8, and the output signal 10 of the photoelectric switch 2 is used as shown in FIG. The switching element of the AC switch circuit 11 is operated to cause the lamp 1 to blink. In this case, the lamp 1 can be turned on only when the light receiving element 8 receives light, or conversely, the lamp can be turned on only when the light is blocked.

If a large number of photoelectric switches 2 that perform these operations are arranged side by side around the periphery of the light-shielding rotary disk 3, the AC switch circuit 11 is provided corresponding to each photoelectric switch 2, and a lamp 1 is connected to each, When the notches 4 of the light-shielding rotary disk 3 pass through the respective photoelectric switches 2, the individual lamps blink in sequence according to the pattern of the light-shielding rotary disk 3. Also, two or more lamps may be connected to each AC switch circuit and blinked at the same time.

As shown in FIG. 2, the light-shielding rotary disk 3 may be an opaque disk made of metal, synthetic resin, cardboard, or wood with cutouts 4 or light-transmitting windows, or a transparent acrylic resin plate may be used. It is also possible to use a transparent disc made of transparent synthetic resin or glass, on which a light-shielding pattern consisting of a light-transmitting part and a light-shielding part is drawn. Furthermore, as shown in FIG. 4, a transparent disk is divided into concentric circular sections as the light-shielding rotating disk, and each concentric circular section has an independent light-shielding pattern.
As shown in Fig. 5, photoelectric switches 2a, 2
b, 2c, . . . instead of being arranged side by side along the circumference of the light-shielding rotary disk 3, they may be arranged side by side corresponding to each concentric circle section above in the radial direction of the disk. In this case, each photoelectric switch 2a, 2b, 2c, . 1b, 1c, . . . can be made to blink completely independently and arbitrarily.
Furthermore, as shown in FIG. 6, the photoelectric switches 2 may be arranged two-dimensionally in the radial direction and the radial direction of the light-shielding rotary disk. In this case, several sets of lamps each consisting of a plurality of lamps can be blinked independently, and the lamps belonging to each set can be made to blink sequentially.

As the light source of the photoelectric switch 2, a semiconductor light emitting element such as a light emitting diode is preferably used, but a light source such as a filament light bulb or a discharge tube can also be used.
Further, a light source may be provided for each photoelectric switch corresponding to the light receiving element, or all the light receiving elements may be irradiated with one light source.

As the light receiving element 8, a semiconductor light receiving element such as a photodiode or a phototransistor is preferably used, and a so-called optical coupling interrupter, which is a combination of a light emitting element and a light receiving element, is preferably used as a photoelectric switch.

As shown in FIGS. 7 and 8, the light-shielding rotary disk 3 is detachably fixed to the motor shaft 6 with a set screw 12 so as to rotate together with the motor shaft. Width 1 of the light-shielding portion at the periphery of the light-shielding rotary disk 3
By changing 3 and the interval 14, the lighting and extinguishing times can be arbitrarily changed without changing the rotation speed of the motor, and the advertising lighting can be made to blink in an arbitrary pattern by changing the pattern of the light shielding part. I can do it.

Also, three or more photoelectric switches 2a, 2b, 2c...
... are arranged at equal intervals along the circumference or concentric circles of a light-shielding rotary disk, and advertising lighting lamps are arranged cyclically in the order of 1a, 1b, 1c, etc., as shown in Fig. 1, and photoelectric switches are installed. 2a by each lamp 1a
If a plurality of lamps corresponding to each photoelectric switch are made to blink, such as each lamp 1b by the photoelectric switch 2b and each lamp 1c by the photoelectric switch 2c, the light-shielding rotary disk can be shaded at equal intervals. By using a pattern and changing the pitch P of the light-shielding pattern, the blinking of the lamp in Fig. 1 can be freely moved in the direction of the arrow in the figure or in the opposite direction without changing the rotation direction and rotation speed of the light-shielding rotating disk. , and its movement speed can be changed freely.

For example, by rotating the light shielding rotary disk shown in FIG. 2 in the direction of the arrow, three photoelectric switches 2a, 2b, 2
When c is arranged at equal intervals (distance W between the centers of adjacent light receiving elements) as shown in the figure, in part A, 1a, 1b, 1
The flashing of the lamp moves in the order of c, and in the B part, the blinking of the lamp moves in the order of 1.
The blinking of the lamp moves in the order of c, 1b, and 1a.
In part C, all lights are on, in part D, the blinking moves in the order of 1a, 1b, 1c at a faster speed than in part A, and in part E
In the part, the blinking moves in the order of 1c, 1b, and 1a at a faster speed than in the B part, and in the F part, all lights are turned off. (If the AC switch circuit is set to turn on when light is received).

In order to make it easier to understand this blinking state, the blinking states of the lamps in portions D and B are illustrated in FIGS. 9 and 10. Time is plotted on the horizontal axis, and lamps 1a, 1b, 1c, 1a, 1b, 1c, . As shown in FIG. 9, the blinking moves in the directions of 1a, 1b, and 1c in the D section, and as shown in FIG.
The blinking appears to move in the order of 1b and 1a.
In this way, by only slightly changing the light-shielding pattern, the direction of movement of the blinking lamp can be reversed without changing the rotation direction of the light-shielding rotary disk.

In general, three or more n photoelectric switches are arranged at equal intervals with a center-to-center distance W along the circumference or concentric circles of a light-shielding rotating disk, and the light-shielding rotating disk with an equally spaced light-shielding pattern is used as the photoelectric switch 2a. , 2b, 2c, and if the pitch of the light-shielding pattern is P, then P=n/mn+1W (1) (where m is an integer of 0, 1, 2, 3,..., and n is When the relationship (integers 3, 4, 5...) is established, the lamp blinks smoothly in the directions 1a, 1b, 1c... Similarly, when the relationship P=n/kn-1W (2) (where k is an integer of 1, 2, 3, etc., and n is the same as above) holds true, the lamp blinks...
...moves smoothly in the directions of 1c, 1b, and 1a.

As the pitch P of the light shielding pattern deviates from the above relational expression, the blinking of the lamp will no longer move smoothly, but if the deviation is within a certain range, it will appear to move in the forward or reverse direction. As the discrepancy becomes large, the lights will start blinking intermittently.
The moving speed of the flashing is proportional to the rotational speed of the light-shielding rotary disk and inversely proportional to the pitch P.

According to the present invention, since a photoelectric switch is used, there is absolutely no risk of contact failure as occurs in conventional flashers using mechanical contact switches, and stable operation can be achieved without failure for a long period of time.

In addition, any blinking pattern can be realized by using a shading pattern, and by using equally spaced shading patterns to move the blinking of a large number of lamps, and changing the pitch of the shading patterns, the speed and movement of the blinking can be adjusted. The direction can be changed and reversed. Moreover, by simply rotating one light-shielding rotary disk in a fixed direction at a fixed speed, the moving direction and speed of blinking of the lamp can be reversed and changed at will.

If a plurality of light-shielding patterns are displayed concentrically on a light-shielding rotary disk and photoelectric switches are arranged in a radial direction, the lamps can be turned on and off completely independently.

Furthermore, by preparing several light-shielding rotary discs with different light-shielding patterns and replacing them as appropriate, there is a very remarkable effect that the flashing pattern can be easily changed at any time.
