Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light emitting fan provided with a function of a fan and a function of emitting light.

[0002]

2. Description of the Related Art Light emission equipped with a power supply and a small lamp such as an LED in order to obtain beauty when used at night or in a dark place, or display effect in performance of individuals or groups (dance, march, gesture, etc.). Various types of fans have been proposed in the past. Its main structure is as follows. (1) A light guide is made by forming the fan bone with a transparent material,
The light of the light source provided at the important position is made incident on the bone, and the tip of the bone,
Alternatively, the structure is such that light is scattered and emitted from the bone itself. (2) A structure in which LEDs and the like are arranged at several places on the fan surface, and a light source is connected to a power source built in the handle by a wire to emit light. (3) A structure in which light from a light source incorporated in the handle portion is guided to various places on the fan surface using a light guide such as an optical fiber, and the portion emits light.

[0003]

The superiority and inferiority of the above-mentioned respective configurations of the conventionally proposed light-emitting fan will be compared. (1) It is possible to provide the simplest structure and most likely to supply the light-emitting fan at low cost. (2) Since a large number of light sources are used and wiring is performed, the structure becomes complicated, the manufacturing and assembling cost is increased, and the fan surface has irregularities, and it is difficult to obtain the flexibility and smart appearance of the fan surface. Also, the strong light emission of the light source on the fan surface may be felt dazzling. (3) Although the degree of freedom in arranging the light emitting points (bright points) is high, the structure is still complicated and the cost problem is large. This is remarkable as the number of light emitting points increases.

From the above consideration, it was discovered that the conventional example (1) is close to the most preferable structure, but when actually manufactured and used, the following problems occur. 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 the bone is invisible or weakened, and the light effect is reduced. (2) If a transparent sheet is attached to the fan surface, the light emission of the bone can be seen well, but in the daytime or in a bright place, the surface becomes a monotonous fan surface, and the enjoyment in use cannot be obtained. (3) It is possible to draw a pattern that can be seen in the light on the fan surface, but in the dark the pattern becomes a silhouette or color filter, which hinders good visual recognition of the light emission of bones.

The first object of the present invention is to emit light beautifully in a dark place.
And keep manufacturing costs low
It is to provide a luminous fan that can. The second
It is an object of the present invention to provide a light-emitting fan which can display a beautiful pattern or pattern on the fan surface not only in the dark place but also in the light place, and can keep the manufacturing cost low.

(B) is a side view. FIG. 3 is a plan view of the fan plate in the same example.

[0011] 1 in FIG. 1 and FIG. 2 is a skeleton of a fan, is molded transparent material or these acrylic resins, the sharp lateral transformant of the main portion of the thickness of large skeletal base 1a (top view The upper end of the base 1c above it
Therefore, it is composed of a large number of radial bones 1g having a thickness slightly smaller than that (the middle portion thereof is a window portion 1h having no member), and a substantially circular edge member 1f connecting the ends thereof. Skeleton base 1
In the portion a, there are a large number of shallow recesses 1j on both sides,
The middle part of them remains as a pseudo bone 1k. The light incident portion 1b is cut in the vicinity of the radiation center of the radial bone 1g, the pseudo bone 1k, and the concave portion 1j.
An elongated slot 1i for decoration is formed. The skeleton 1 is a main light guide for the light emitted from the light source.

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

A cap 5 is fitted on the lower end of the handle 4. A battery spring 3f, which is a coil spring having a generally 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 that part rotates the cap 5 to a predetermined position, the lower end of the extension lead wire 3d comes into contact with the power supply circuit to close the main switch. LED 3a emits light. The hanging ring portion 5c provided at the lower end of the cap 5 is for hanging a fan on a neck or a wrist through a string or a chain, and if it is provided, it is extremely convenient in use. The pair of internal protrusions 5b formed on the cap 5 engages with the cam groove 4b formed shallowly around the lower end of the handle 4.

The cam groove 4b is formed along the cylindrical surface of the handle 4 in FIG.
Since the internal projection 5b has the shape shown in the developed view of (c) and is pushed downward by the repulsive force of the battery spring 3f, the cam groove 4
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 internal protrusion 5b is first inserted from the point A of the cam groove 4b, and gets over the protrusion of B to settle at the low point C. At 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 to the right, the internal projection 5b gets over the convex point D having slopes on both sides and reaches the point E to settle down. At this position, the lower end of the battery spring 3f contacts the extension lead wire 3d, the circuit is closed, and the LED 3a emits light. Turn the cap backwards to cut the circuit and extinguish.

The light emitting portion of the light source LED 3a is located at the center of the thickness of the skeleton base portion 1a in the light incident portion 1b portion, and the light flux 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 with a change in cross section, particularly a portion with a sharp change in cross section, it is emitted to the outside and shines. Each bright spot in FIG. 1 represents a cross-section reduced portion which is a main light emitting spot. The bright spot 6a is the lower end of the recess 1j, and the bright spot 6b is the base upper end 1.
Light is emitted from the edge member 1 at the bright spot 6c, which is the portion from c to the radial bone 1g.
This is the portion that has reached the outer end of f.

In the present example, a large number of main light emitting points are closely arranged on several arcs, and in a dark place, these bright points are connected in a curved line and are very beautiful. In addition, some light is emitted from other parts and uneven portions on the surface of the skeleton. The fan plate 2 also diffuses the light emission. These look beautiful like an aura. Also, it is possible to increase the number of light emitting points by providing a horizontal bone. In addition, it is convenient 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 emission of the light source LED 3a is strong, glare may be felt when directly viewed. Handle 4 is LED3a
Since it wraps both sides of the, it can overcome the difficulty by selecting the light transmittance of the material. Ie LED
An opaque member may be used as the material for covering 3a (coupling portion 4a in this example), but when molded with a light-attenuating, that is, transparent but dark resin material, glare is appropriately suppressed, Moreover, the presence of a light source can be clearly specified to add a further aesthetic effect.

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 the wind-up surface caused by the fan's fanning action, and also exhibits the aesthetic effect of the fan in the light.
In a dark place, it has a role of not hindering the light emission of the fan surface as much as possible.
As a result of various studies, the present inventor determined that a transparent hologram sheet (may be referred to as a film) would be most suitable.

The hologram sheet is a transparent, colorless and flexible P sheet.
The bottom surface of a resin film such as ET, PVC, OPP, etc. is subjected to fine unevenness or striped embossing at the wavelength level of visible light that can interfere with reflected light, and thin aluminum etc. is vapor-deposited on the embossed surface to form a hologram surface. It has a very beautiful color like a rainbow 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 unevenness, the illumination and the viewing angle. In addition, free contour patterns and designs can be formed.

Moreover, it is colorless when viewed in terms of transmitted light (does not color transmitted light), and is quite transparent like frosted glass with a weak degree, and even when it is attached to the fan surface (due to the adhesive coated on the back surface of the fan face plate). You can see the radiating bones, and you can see the fingers close to the fan plate. Therefore, light emission from the skeleton near the inner surface or the edge of the fan body 2 is not impeded at all. On the contrary, the light flux passing through the skeleton illuminates the hologram sheet from the back side,
Since the incident angle was so close to parallel to the surface that the hologram pattern was not visible even in a dark place, it was extremely convenient for the application of this example.

It goes without saying that the embodiment of the present invention is not limited to the example described above. For example, the shape of the entire fan, the shape of each part, the direction of the light guide member such as the radiating bone, and how to change the cross section are arbitrary. The emission color of the LED can be arbitrarily selected. The light emitting points can be arranged linearly. Also, since there are various types of holograms, it is possible to select one that is acceptable for the purpose. Further, a member (thin paper or the like) capable of displaying by external light with a certain degree of translucency by means other than the hologram can be used. Further, the displayed pattern or pattern is completely arbitrary, and may be a character or a mark. It is also possible to provide two or three light sources, divide the group of light emitting points into light sources of different colors, or mix colors at the light emitting points to achieve a more complex light effect.

Further, not only the light emission is continuously turned on / off by the main switch, but by adding a further light emission control means, the light emission can be changed non-steadily. Further examples of the control means include a push switch that can be controlled by the thumb of a hand holding a handle, a microcomputer and a semiconductor switch that rhythmically change the light emission timing and intensity, or a swing switch and an acceleration sensor that move the movement of a fan. There may be a means for controlling light emission according to the direction of movement, intensity, or pattern, etc. These means allow individual users or groups to highly transmit information and messages, and are highly effective in performance performance.
