Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention uses this device to give continuous color changes to the irradiated light. Then,
The present invention relates to a decorative lighting device for giving a color effect to a screen.

[Prior Art] Conventionally, as a decorative lighting device to bring a color effect to a screen, a plurality of cams each having cam ridges with different phase shapes arranged around the circumference are arranged in series on the same axis and tightened together. A mechanical structure in which a series of spring-type relays are integrated into a cam crest and has the function of a relay switch is used, and this is already known. However, such devices are prone to contact failure due to spring deformation, cam mount wear, loosening, etc., making maintenance and inspection before and after use a hassle, and causing uneven color changes. There were flaws. Furthermore, when using multiple units, it is inconvenient to operate, and problems arise in terms of weight and space.

[Problems to be solved by the invention] Conventional lighting devices with a mechanical structure have many of the drawbacks mentioned above and are difficult to obtain color effects. The aim is to propose a lighting device that can produce color effects that have not been previously available.

[Means for solving the problems] Means for solving the problems described above will be explained below based on the attached drawings corresponding to the embodiments.

The rotary plate 1 includes a motor 3 having a predetermined rotation speed and a rotary plate 1 that is rotatably supported by the motor. a control unit having a main timing circuit that detects the passage of the motor with a photo sensor 4 and transmits a synchronization signal to the drive unit; a motor 13 and a rotary plate 11 whose rotating surface supported by the motor 13 has a different color. The rotary plate 11 has a slit B in a part of the light shielding part 12 formed on the periphery, and this slit B is detected by the photo sensor 14 to stop the motor 13 and respond to the synchronization signal. and a light source section provided for a light emitting means by an optical fiber, one end of which is disposed facing the rotary plate 11 of the drive section. In the lighting device, the photo sensor 4 detects passage of the control section through the slit A, and the main timing circuit transmits a synchronization signal to the drive section. In the driving section, the slit B is detected by the photo sensor 14 and the motor 13 is stopped, and the motor 13 is rotationally driven by the sub-timing circuit in response to the synchronization signal. Since such operations are continuously repeated, technical measures are taken to enable continuous illumination of color-changing light to the front surface of the rotating plate 11 using the light source section.

As a result, the irradiation light can provide illumination with a continuous color change to the screen having the light emitting part using the light emitting means using the optical fiber.

[Function] When the input power source is connected, the motor 3 of the control section constantly rotates. The input power to the main timing circuit is cut off while the light shielding part 2 of the rotary plate 1 of the control section is at the photo sensor 4, but when the slit A passes the photo sensor 4, the input power is input to the sub timing circuit of the drive section. Power is supplied and a synchronization signal is formed.

The sub-timing circuit is different from the main timing circuit, and when the slit B passes the photo sensor 14, the power to its own sub-timing circuit is cut off and the motor 13 is stopped. Thereafter, the motor 13 that has stopped rotates again in response to a synchronization signal from the main timing circuit, and the slit B is connected to the photo sensor 1.
After passing through 4, it rotates using the power supply of the sub-timing circuit.

As described above, by continuously and repeatedly driving the motor 13, it is possible to obtain illumination that transmits through the rotary plate 11 and exhibits a color effect as irradiated light with continuous color changes.

[Embodiments] (1) Structure of the embodiments The present invention will be described below based on the attached drawings, which are shown as preferred embodiments of the present invention.

First, in the control unit shown in FIG. 1, numeral 1 is a transparent rotary plate, and a light-shielding part 2 having a constant width is formed on the periphery of the plate, and a part of the light-shielding part 2 is cut out with an appropriate gap. Equipped with slit A.

Reference numeral 3 denotes a motor having a predetermined rotation speed, which is screwed onto the upper ends of two columns fixed upright to the base plate 7, and the rotary plate 1 is pivotally supported. Reference numeral 4 denotes a transmission type photo sensor, and an angle member is installed near the outer periphery of the rotary plate 1 using a motor mounting post at a position where the light shielding part 2 can pass through the gap between the photo sensors 4 while rotating without contacting the photo sensor 4. It is attached through.
5 shows the main timing circuit panel, including silicon bridges, capacitors, miniature relays,
Small components such as silicon diodes, carbon resistors and transistors are electrically connected and mounted on the panel 5 to form part of the main timing circuit shown in FIG. 6 is a transformer that steps down the input power and supplies it to the circuit.

Next, in the driving section shown in FIG. 2, reference numeral 11 denotes a transparent rotary plate, and like the rotary plate 1, a light shielding part 12 having a constant width is formed on the periphery, and a slit is formed in a part of the light shielding part 12 having a constant width. It has B. In addition, rotating plate 1
1 has different colors applied in a fan shape.
The motor 13 has a predetermined number of rotations, and is screwed onto the base plate 17 via a housing frame in which a light source section is provided, and the rotary plate 11 is pivotally supported on this frame. A transmission type photo sensor 14 is mounted on the right side of the upper plate of the housing frame, and the positional relationship between the photo sensor 14 and the light shielding part 12 is the same as that in the control part. Reference numeral 15 designates a sub-timing circuit panel, in which small components similar to those in the main timing circuit panel 5 of the control section are electrically connected and mounted to form part of the sub-timing circuit shown in FIG. There is. 16 is a transformer that steps down the input power and supplies it to the circuit.

In addition to the above, on the base plate 17, on the back side of the rotating plate 11, the light source of the halogen lamp 18 is located directly below the center of the rotating plate radius, and a reflecting mirror 19 is placed on the base plate 17.
A light source unit is provided. As a result, the reflected light from the halogen lamp passes through the glass plate 20 and colored illumination light is emitted from the upper surface of the rotary plate 11.

(2) Operation of the embodiment In the above configuration, when the input power source is connected, the motor 3 of the control section constantly rotates. At the same time, the rotating plate 1 rotates. While the light shielding section 2 passes through the photo sensor 4, the photo sensor 4 is shielded from light, and the contacts of the miniature relay RL ₁ on the panel 5 of the main timing circuit are in the ON state.
Input power is cut off. Furthermore, when the motor 3 continues to rotate and the slit A passes the photo sensor 4, the contacts of the miniature relay RL ₁ turn off, and the input power is supplied to the sub-timing circuit of the drive section, causing the motor 13 to rotate. .

Next, in the sub-timing circuit of the drive section, unlike the case where the motor 2 of the control section is always rotating when the input power is connected, the motor 1 is rotated in this way.
3 rotates, the rotating plate 11 also rotates, and when the slit B passes the photo sensor 14, the contacts of the miniature relay RL ₁₁ are turned on, cutting off the input power, and as a result, the motor 13 is stopped. Next, the stopped motor 13 receives a synchronization signal from the main timing circuit of the control section and starts rotating again, and then the slit B is connected to the photo sensor 14.
At the point when the miniature relay RL 11 passes through, the contacts of the miniature relay RL ₁₁ are turned on, and the miniature relay RL 11 is rotated by the sub-timing circuit of its own drive section.

As described above, in response to the synchronization signal from the main timing circuit of the control section, the motor 13 of the sub-timing circuit of the drive section is driven to repeatedly rotate and stop. Note that the synchronization time of this synchronization signal is determined by the width of the gap between the slits A.

Next, the halogen lamp 18 is turned on by the power voltage lowered by the transformer 16, reflected by the reflecting mirror 19, transmitted through the transparent glass 20, and irradiates the front surface of the rotary plate 11 with colored light.

Therefore, while the rotary plate 11 is rotating, by applying this irradiation light to the light emitting means of the optical fiber, a continuous color effect that follows the color applied to the rotary plate 11 is produced on the screen having the light emitting part. It will be demonstrated.

In the above embodiment, one drive unit is used for one control unit, but by connecting a plurality of drive units to one control unit, a color effect with further diversified color changes can be obtained.

[Effects of the Invention] According to the present invention, this device uses an optical fiber for the irradiation light so that the color of the screen having the light emitting section can be continuously and smoothly changed. For example, like a landscape painting on a screen, by using colors that take advantage of the characteristics of each season, it is possible to provide lighting with a color effect that creates the scene and atmosphere of the season and attracts the interest and attention of the viewer. Further, since the lighting device according to the present invention is an electrical device instead of a mechanical structure, it is lightweight and compact, and does not require special inspection and adjustment.
