An artificial stick and an edge member are arranged to increase the light emitting points, and these members are linearly arranged. A beautiful appearance is obtained in a bright place by using a hologram sheet for the fan face plate. A glare-proof means, a suspending ring, and an emitting light control mechanism can be included.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting fan having a function of emitting light as well as a function of the fan.

[0002]

2. Description of the Related Art A light source equipped with a power supply and a small lamp such as an LED has been developed in order to obtain a beautiful display when used at night or in a dark place, or a display effect in an individual or group performance (dance, march, gesture, etc.). A wide variety of round fans have been proposed. The main configuration is as follows. (1) The fan bone is made of a transparent material to form a light guide,
The light of the light source provided at the required position is incident on the bone, and the tip of the bone,
Or a configuration in which light is scattered from the bone itself. (2) A configuration in which LEDs and the like are arranged at several places on the fan surface and connected to a power supply built in the handle portion by wiring to emit light. (3) A configuration in which light from a light source incorporated in a pattern portion is guided to various portions of a fan surface using a light guide such as an optical fiber, and the portion emits light.

[0003]

A comparison will be made between the above-described structures of the conventionally proposed luminous fan. (1) The simplest structure can be obtained, and the possibility of supplying light-emitting fans at low cost is the highest. (2) Since a large number of light sources are used and wiring is performed, the structure is complicated, the cost of manufacturing and assembling is increased, and the fan surface has irregularities, and it is difficult to obtain a flexible and smart appearance of the fan surface. In addition, the strong light emission of the fan-side light source may be felt dazzling. (3) Although the degree of freedom in the arrangement of the light emitting points (bright points) is high, the structure is still complicated and the cost problem is great. This is severe as the number of light emitting points increases.

[0004] From the above considerations, it is found that the conventional example (1) is close to the most preferable configuration, but has the following problems when actually manufactured and used. That is, (1) paper or the like must be attached to the fan surface, but if the material is opaque or has low light transmittance, light emission from bones is invisible or weakened, and the light effect is reduced. (2) If a transparent sheet is stuck on the fan surface, the light emission of the bones can be seen well. However, in the daytime or in a bright place, the fan surface becomes completely monotonous and the enjoyment of use cannot be obtained. (3) A pattern that can be seen in a bright place can be drawn on the fan surface, but in a dark place, the pattern becomes a silhouette or a color filter, which hinders good visibility of light emission of bones.

SUMMARY OF THE INVENTION It is an object of the present invention to provide a beautiful light emission effect in a dark place and an excellent light effect, and to display a beautiful pattern or pattern on a fan surface even in a bright place, and to reduce the manufacturing cost. It is to provide a luminous fan.

[0006]

In order to achieve the above object, the light emitting fan of the present invention has the following features. (1) A handle accommodating a power supply therein, a skeleton of a fan made of a transparent material joined to one end of the handle, and one of the handles so that a light beam enters the inside of the skeleton. Consisting of at least one LED light source disposed near the end and a fan plate adhered to the surface of the skeleton, the fan plate is substantially transparent on the entire surface or most of the surface, and is visible by external light. Have a pattern or design.

[0007] The light emitting fan of the present invention may further have at least one of the following features. (2) The pattern or design of the fan plate can be visually recognized by light interference. (3) The fan plate is a hologram sheet that is almost colorless and highly transmissive to transmitted light, but allows a pattern or pattern colored by reflected light to be seen.

(4) The skeleton has radial bones or pseudo bones arranged radially, and the radial bones or pseudo bones are arranged in a direction toward a light emitting point of the LED light source. (5) The skeleton has a plurality of cross-section changing portions in a process of moving away from the light emitting point of the LED light source, and each of the cross-section changing portions is arranged on a curve or a straight line.

(6) At least one end of the handle is formed of an opaque material or a material having a light attenuating effect, and the LED light source is covered by one end of the handle to emit light of the LED light source. That glare is suppressed. (7) At the other end of the handle, a hanging ring through which a string or the like can be passed is provided. (8) The light emitting fan is connected to the L
Other control means for controlling light emission of the ED light source is provided.

[0010]

FIG. 1 shows a light-emitting fan as an example of an embodiment of the present invention, wherein (a) is a plan view, (b) is a side view, and (c) is a developed view of a cam groove. . FIG. 2 shows a skeleton of a light-emitting fan in the same example, (a) is a plan view,
(B) is a side view. FIG. 3 is a plan view of a fan plate in the same example.

1 and 2, reference numeral 1 denotes a skeleton of a fan, which is made of a transparent material such as an acrylic resin or molded, and whose main part is a skeleton base 1a having a large thickness (the shape in the plan view is sharp on the left and right sides). The upper end of the base 1c
Therefore, it is composed of a number of radial bones 1g slightly thinner than that (the middle is a window portion 1h without any member), and a substantially circular edge member 1f connecting the ends thereof. Skeleton base 1
The portion a has a large number of shallow concave portions 1j on both surfaces thereof.
The middle part remains as a pseudo bone 1k. The light incident portion 1b is cut in the vicinity of the radiation center of the radiation bone 1g, the pseudo bone 1k, and the concave portion 1j, and the mounting portions 1d,
An ornamental long hole 1i is formed. The skeleton 1 is a main light guide for light emitted from the light source.

In FIG. 1, a fan handle 4 is composed of two members sandwiching a fan surface and assembled with a skeleton sandwiched therebetween.
The lower part of the figure is assembled in a cylindrical shape, and accommodates a battery 3e such as a AAA battery serving as a power supply therein. The connecting portion 4a having an enormous shape in the upper right and left directions is firmly connected to the skeleton 1 by fitting a pin-like projection (not shown) therein to a fixing hole 1e of the mounting portion 1d of the skeleton 1. In the internal space of the coupling portion 4a, an LED 3a serving as a light source, a resistor 3b connected to one terminal of the LED 3a and serving as a part of a light emitting circuit, a positive electrode plate 3c connected thereto and in contact with a positive electrode of a battery 3e are supported. You. Also, an extension lead wire 3 connected to the other terminal of the LED 3a.
d is extended and held inside the handle to its lower end.

A cap 5 is fitted into the lower end of the handle 4. A battery spring 3f, which is a coil spring wound in a conical shape, is fixed to the spring pedestal 5a therein. The upper end of the battery spring 3f pushes up the negative electrode of the battery 3e. A part of the lower end of the battery spring 3f protrudes in the radial direction, and only when the part rotates the cap 5 to a predetermined position, it comes into contact with the lower end of the extension lead wire 3d to close the power supply circuit (becomes a main switch). ), The LED 3a emits light. The suspension ring 5c provided at the lower end of the cap 5 is used for hanging a round fan on a neck or a wrist through a string or a chain, so that the convenience is greatly improved in use. A pair of internal projections 5 b formed on the cap 5 are engaged with a cam groove 4 b formed shallow around the lower end of the handle 4.

The cam groove 4b is formed along the cylindrical surface of the handle 4 as shown in FIG.
Since the internal projection 5b is pressed downward due to the repulsive force of the battery spring 3f, the cam groove 4 is formed.
The lower edge of b is the main cam surface. When the cap 5 is pushed into the handle 4 while being twisted to the right, the inner projection 5b is first inserted from the point A of the cam groove 4b, gets over the projection B, and settles at the lower point C. In this position, the protrusion of B prevents the cap 5 from coming off, and the light emitting circuit is not yet closed. When the cap 5 is further turned clockwise, the inner projection 5b gets over the point D having the slopes on both sides, reaches the point E, and calms down. In this position, the lower end of the battery spring 3f contacts the extension lead wire 3d to close the circuit, and the LED 3a emits light. The circuit is cut off by turning the cap backwards and extinguished.

The light emitting portion of the light source LED 3a is located at the center of the thickness of the skeleton base 1a at the light incident portion 1b, and the light beam enters the inside of the skeleton 1 and spreads radially over the entire fan surface. In the process, if there is a portion of the skeleton 1 where the cross-section changes, particularly a portion where the cross-section shrinks and changes rapidly, it radiates to the outside and shines. Each luminescent spot in FIG. 1 indicates a cross-section reduction site that is a main light emitting point. The bright spot 6a is at the lower end of the recess 1j, and the bright spot 6b is at the upper end 1 of the base.
The bright spot 6c is where the light is transferred from the edge member 1 to the radiating bone 1g.
This is the portion that has reached the outer end of f.

In the present embodiment, a number of main light emitting points are closely arranged on several arcs, and in a dark place, these bright points are extremely beautiful in a curved line. It should be noted that some light is emitted also from other parts and uneven portions on the surface of the skeleton. The fan plate 2 also diffuses light emission. These look beautiful like an aura. Even if the transverse bone is provided, the number of light emitting points can be increased. It is advantageous in terms of light emission and fan strength that the cross-sectional thickness and width of the skeleton 1 gradually decrease from the skeleton base 1a toward the edge member 1f.

Since the light source LED 3a emits light intensely, it may be glare when viewed directly. Pattern 4 is LED3a
Since both sides are covered, the difficulty can be overcome by selecting the light transmittance of the material. Ie LED
An opaque material may be used as the material of the member (the joining portion 4a in this example) covering the 3a, but glare is appropriately suppressed by molding with a light-attenuating, that is, transparent, but dark resin material, In addition, it is possible to add the further aesthetic effect by clearly indicating the existence of the light source.

The fan-shaped plate 2 in the form of a thin film or sheet is attached to both sides of the radial bone 1g and the edge member 1f, and has a pattern 2a on the surface. This is not only the surface of the wind fan fan, but also the aesthetic effect of the fan in the light,
Also, in a dark place, it has a role of preventing light emission from the fan surface as much as possible.
As a result of various studies, the present inventor has determined that a transparent hologram sheet (which may be referred to as a film) will be optimal.

The hologram sheet is a colorless, transparent and flexible P
ET, PVC, OPP, etc., the surface of the resin film, such as visible light wavelength level fine irregularities or stripes embossing that can interfere with the reflected light, aluminum, etc. is thinly deposited on the embossed surface and the hologram surface It has a very beautiful rainbow-like color when illuminated. The illumination light has a strong aesthetic effect whether it is sunlight or artificial light. The color changes depending on the arrangement direction of the fine irregularities, the illumination, and the viewing angle. In addition, a free contour pattern or pattern can be formed.

Moreover, when viewed from the transmitted light, it is colorless (does not color the transmitted light), is quite transparent like frosted glass of a weak degree, and can be adhered to the fan surface (by the adhesive coated on the back of the fan plate). Radiant bones are visible, and fingers close to the fan panel are clearly visible. Therefore, light emission from the skeleton near the inner surface or the edge of the fan 2 is not hindered at all. Conversely, the luminous flux passing through the skeleton illuminates the hologram sheet from the back,
Since the incident angle was too close to the plane, the hologram pattern was not visually recognized even in a dark place, which was extremely convenient for the use of this example.

The embodiment of the present invention is, of course, not limited to the example described above. For example, the shape of the whole fan, the shape of each part, the direction of the light guiding member such as the radiating bone, and the way of giving a change in cross section are arbitrary. The emission color of the LED can be arbitrarily selected. The light emitting points can be arranged linearly. Since there are various types of holograms, it is possible to select a hologram that is acceptable for the purpose. In addition, if there is a member (thin paper or the like) that can be displayed by external light with a certain degree of translucency by means other than the hologram, it can be used. The displayed patterns and designs are completely arbitrary, and may be characters or marks. In addition, two or three light sources can be provided, and a group of light emitting points can be divided into light sources of different colors or mixed at light emitting points to achieve a more complicated light effect.

In addition to the continuous on / off operation of the light emission by the main switch, the addition of a further light emission control means has an effect of changing the light emission irregularly. Examples of further control means include a push switch that can be controlled by the thumb or the like of the hand holding the handle, a microcomputer and a semiconductor switch that rhythmically change the light emission timing and intensity, or a swing switch or an acceleration sensor that moves the fan. There may be a means for detecting light with a rotation angle speed sensor or the like and controlling light emission according to the direction, intensity, or pattern of the movement. These means allow users or groups to transmit information and messages at a high level, and are highly effective in performing performance.

[0023]

According to the present invention, a pattern or a pattern can be displayed by external light, and since a substantially transparent fan plate is used, light emission from the skeleton and diffused light of the fan plate itself can be visually recognized well, and even in a light place or a dark place. However, there is an effect that a beautiful luminous fan with a high light effect is obtained. Also, when a member or a hologram sheet that displays a pattern or pattern on the fan panel by light interference, particularly a nearly colorless hologram sheet, does not disturb the light emission from the skeleton and does not change the color. Great effect. In the present invention, the structure of the light emitting mechanism is simple, the manufacture of the light emitting fan is easy, the manufacturing cost can be sufficiently suppressed, and the supply can be performed at low cost.

The following further effects can be obtained by adding another structure. The structure in which the main part of the transparent skeleton is directed to the light source allows light to be efficiently used to emit light. In addition, by arranging a large number of cross-section changing portions into a plurality of groups and arranging them on a simple curve, the bright spots can be arranged beautifully. Further, by using an opaque or light-attenuating material for a part of the handle, glare caused by direct light from the light source can be avoided. In addition, the provision of the suspension ring allows the luminous fan to be hung on, for example, the neck, so that both hands are free and can be used much more conveniently. Further, by providing a light emission control means other than the main switch, the light effect can be further diversified.
