Description

Description: BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a gradual multicolor illuminating device, and its purpose is to simply and gradually spread light, stop and close as one cycle, and perform a movement. Provide a gradual multi-color illuminator with a high production effect that can gradually change the illumination light color, and use this gradual multi-color illuminator in displays for department stores, stores, exhibitions, stage lighting, ceremonies for weddings, etc. It is useful for a wide range of uses such as directing or warning at the time of warning.

(Prior art) Conventionally, displays of department stores, stores, exhibitions, etc.,
Various lighting devices are used for stage lighting, ceremonies such as weddings, and the like, in order to complement or direct products, the stage, the ceremonies, and persons, respectively.

Among the lighting methods used for such a purpose, a lighting method of locally illuminating a product, a person, an object, a stage, or the like using a spotter light or the like is generally widely used.

However, the local illumination method using a spotlight has no change such that the illumination light spreads or narrows, and constantly applies the same illumination light to an object without a color change. It was inadequate from the point of view of directing people to show off.

In addition, recently, at the ceremony venues such as the stage, wedding ceremonies, exhibition halls, exhibition halls, etc., it is possible to change the color of the illumination light by rotating the color filter and changing it to other color filters. Lighting equipment is used.

Further, there is also used an illumination device or the like in which an opening / closing device is provided in the illumination device to adjust the light transmission area so that the size of the illumination light can be freely adjusted by narrowing or expanding the light.

However, these lighting devices alone can only change to various illumination light colors, or can only reduce or expand the illumination light colors, so that they are insufficient from the viewpoint of the rendering effect, and various illumination light colors are insufficient. In order to produce an effect that expects a high effect of changing the color and squeezing or expanding the color of each illumination light, it is absolutely necessary to use a number of illumination devices, which is inefficient.

In addition, these lighting devices are manual and time-consuming, and require large equipment, so it is not only inefficient to use many lighting devices but also practical. In particular, it has not been possible to use the lighting device as a lighting device that is frequently used on a daily basis in a limited narrow space such as a display of a store or a department store, in order to obtain an effect.

(Problems to be Solved by the Invention) In view of the above circumstances, in the industry, it is easy to convert to various illumination light colors, and it is possible to narrow or expand the illumination light colors, so that the effect of highlighting and directing is high, and it is simple and effective. It is desired to create a lighting device that can be used for a wide range of applications.

A gradual multicolor illuminating device according to the present invention is a gradual multicolor illuminating device including a light source, a converging device, a multicolor filter, an eyeless shutter, a driving mechanism, and a light projecting device. The filter has a plurality of disc-shaped light-transmitting holes perforated on the same circumference at equal intervals, and covers each of these holes with a color filter to form a color filter section.The multicolor filter and the eyeless shutter are intermittently driven. The eyeless shutter is connected to a driving device having one cycle of closing, opening, and closing movements, and the intermittent driving device is driven when the eyeless shutter is in a closed state, and the next color filter of the multicolor filter is connected. The eyeless shutter is opened and closed by the drive mechanism. Since the present invention is a gradual multi-color changing illumination device characterized in that the illumination device is configured to reach a closed state through an open state, the above-mentioned problem is completely solved.

(Embodiment) A progressive multicolor changing illumination device according to the present invention will be described with reference to the drawings.

FIG. 1 is a view in which illumination light is projected onto a screen (S) using a progressively multicolored illumination device according to the present invention.

FIGS. 1 (G) to 1 (L) show the second cycle of yellow light (R) following the red (R) illumination light shown in FIGS. 1 (A) to 1 (G). Y) Illumination light over time (along arrow)
It is a figure which shows the yellow light (Y) part projected on a screen (S) at equal time intervals.

Illumination is performed on the periodic movement of the illumination light performed using the gradual multicolor illumination device.

One cycle of the red light (R) illumination light of the first cycle performed by using the progressively multicolored illumination device is such that the illumination light is narrowed down as shown in FIG. (R) It starts from a state where the illumination light is not projected.

Next, as shown in FIG. 1 (B), the illumination light gradually spreads, and the red light (R) portion on the screen (S) gradually increases, and as shown in FIG. 1 (B), about half of the screen (S). It will be large.

Further, the illuminating light gradually spreads, and as shown in FIG. 1 (C), the illuminating light spreads to the maximum and the red light (R) portion of the screen (S) becomes the largest.

The state of FIG. 1 (C) where the red light (R) portion on the screen (S) is the largest is maintained until FIG. 1 (D).

Then, the illumination light is gradually reduced, and the red light (R) portion on the screen (S) is screen (S) as shown in FIG.
Is about half the size of

Further, the illumination light is gradually stopped down, as shown in FIG. 1 (F), so that the screen (S) is not projected with red (R) illumination light again.

Between FIG. 1 (F) and FIG. 1 (G), the state where the illumination light is not projected on the screen (S) continues, and during this time, the color of the illumination light changes from red light (R) to yellow light. One cycle of the red light (R) illumination light ends after being converted into the color (Y).

That is, FIGS. 1A to 1G show one cycle of the red (R) illumination light projected from the progressively multicolored illumination device.

FIGS. 1 (G) to 1 (L) converted into the yellow light (Y) illumination light of the second cycle in this manner also have the above-described FIGS. 1 (A) to 1 (G). 3 shows a projection having the same shape as the projection shown by the cycle of the red (R) illumination light.

Furthermore, the yellow light (Y) illumination light of the second cycle is also gradually converted to the next illumination light color after one cycle ends, and the next illumination light color has the same cycle as the yellow light (Y) illumination light. The movement is performed, and a projection having the same shape as the yellow (Y) illumination light is projected on the screen (S).

In this way, the gradual multicolor illuminating device spreads the red light (R) illuminating light, performs a movement with one cycle of squeezing and closing, and when this one period of movement is completed, the next yellow (Y) illuminating light The movement is performed with one cycle consisting of the expansion, aperture, and closing, and the illumination light color is further gradually converted and expanded, followed by the one-period movement similar to the aperture, closing.

The emission converging device part (a) of the gradual multicolor changing illumination device (1) comprises a light source (2) and a reflecting mirror (3).

The reflecting mirror (3) is a converging device used to converge a light beam generated from the light source (2) and gradually send the light beam to the eyeless shutter opening / closing section (8) of the multicolor changing device portion (b).

In this embodiment, the reflecting mirror (3) is used as a converging device. However, in the present invention, the converging device converges the light beam generated from the light source (2) and sends it to the multicolor changing device portion (b). A convex lens, a concave lens, a combination thereof, and the like can be preferably used.

The gradual multicolor changing device portion (b) of this embodiment includes a multicolor filter (4), an eyeless shutter (7) and a Geneva gear follower (9), a Geneva gear original vehicle (10), a drive rod (11), and a drive gear. (12), a drive mechanism including a motor (13), a driven gear (14), and the like.

The gradual multicolor changing device portion (b) expands the convergent light beam sent from the light emission converging device portion (a), performs a one-cycle motion of closing and closing, and a gradual color change that can be performed in each one-cycle. This is a device portion for converting the light beam into a multicolor light beam and sending the light gradually to the light projecting device portion (c), which will be described later in detail with reference to FIG.

The multicolor filter (4) of the gradual multicolor changing illumination device (1) has five disc-shaped light-transmitting holes (5) formed at equal intervals on the same circumference.

The position where the multicolor filter (4) is provided is a position where the same circumference where the disk-shaped light-transmitting hole (5) is provided passes over the center of the eyeless shutter opening / closing portion (8), more specifically, the disk-shaped light-transmitting hole. It is preferable to be provided on the same circumference where the center of (5) exists.

The reason is that when each disc-shaped light transmitting hole (5) rotates, it is sent to the eyeless shutter opening / closing portion (8),
This is for positioning on the eyeless shutter opening / closing portion (8).

It is desirable that the size of the disc-shaped light transmitting hole (5) is slightly larger than that of the eyeless shutter opening / closing portion (8).

The reason for this is that when the disc-shaped translucent hole (5) is located on the eyeless shutter opening / closing part (8), the disc-shaped translucent hole (5)
Is too small than the eyeless shutter opening / closing part (8), the outer periphery of the light projected to the outside becomes indistinct light and the effect cannot be sufficiently expected. Even if the light emitting hole (5) is too large, the light transmitted to the eyeless shutter opening / closing portion (8) is inefficient because only a part of the disk-shaped light transmitting hole (5) is used as transmitted light. It is.

The reason why the disc-shaped translucent holes (5) are formed at equal intervals on the same circumference is that the multicolor filter (4) is rotated to gradually form the disc-shaped translucent holes (5). This is in order to periodically feed the eyeless shutter opening and closing part (8) at exactly the same position.
