Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention has a light projecting portion having a surrounding light transmitting portion around the front side of a light source, and at least the surrounding light transmitting portion is provided with a colored pattern such as a character having a light transmitting property. The projection illuminating device provided by the present invention is specifically used as, for example, a lighting device for flashlights, advertisement lighting, and a projection device such as a projection toy. The present invention relates to a projection illuminator suitable for carrying and hanging, which can project a silhouette of a predetermined shape.

[0002]

2. Description of the Related Art Conventionally, as a projection type illuminator of this type, for example, a filter having a projection opening formed in the shape of an arrow or the like is provided in front of a light emitting port of a laser device.
There is one that irradiates a light beam of a laser device from the rear of this filter to display a light arrow or the like at a predetermined light projection position in the front.

In particular, as a projection toy, light from a light source is projected to the outside from a plurality of light-transmitting openings on one plane near the light source on the one hand, and on the other hand, a transmissive filter and a reflecting mirror whose design is taken into consideration. In some cases, the light is projected from the other translucent opening in the same direction in the same outside as described above.

[0004]

However, in the former conventional example, since the light intensity of the light beam emitted from the laser device is very high, the arrow of the light beam from the laser device having a strong directivity is careless. If it gets into a person's eyes, it may damage the person's eyes, and since it is a light beam with a strong directivity, it projects light arrows around the wall of the light source, for example, the surrounding wall surface in the room. It is not possible to illuminate with the required brightness together with the light, and the decorativeness around the light source,
Above all, it is not possible to enhance the decorativeness around the room.

On the other hand, also in the latter conventional example, since the light projecting directions are the same, for example, when it is applied to the room, it is possible to exhibit the decorativeness of the light on one wall surface side of the room. However, it is not possible to enhance the overall decorativeness of the interior. In particular, in the case of this conventional example, since the light from the light source is simply projected to the outside in the same direction from the translucent openings on both sides, a considerable part of the light of the light source is the wall surface of the housing around the light source. The structure has a drawback that the light utilization rate is low.

The present invention has been made in view of the above-mentioned problems, and improves the utilization rate of light from a light source, and the surroundings of the light source have a required brightness including a colored or colorless pattern of light such as characters. It is possible to provide a projection lighting device capable of projecting a colored pattern of light such as a character having directivity in another direction by enabling light to be projected by a light source. To aim.

It is characterized in that the bodies 18 and 50 are provided. Further, the surrounding light transmitting portion 41 is characterized in that a light-transmitting character, an animal, a flower, or a desired pattern having various other design characteristics is formed. Alternatively, a transparent film having a light-transmitting character, an animal, a flower, or a desired pattern having various other design characteristics with respect to the surrounding light-transmitting portion 41, or a colored transparent film, or light. It is characterized in that a permeable colored non-transparent film is attached. Further, the reflector 50 of the light projecting section 40 is formed with a projection opening of a required shape having a design property. In addition, a transparent film having a light-transmitting character, an animal, a flower, or a desired pattern having various other design characteristics, or a transparent film having a color property is also provided in the projection openings 54 and 55. It is characterized in that a colored non-transparent film capable of transmitting light is attached. Further, it is characterized in that the light projecting portion 40 can be expanded and contracted with respect to the lighting device main body 10 within a range in which the surrounding light transmitting portion 41 can be housed in the lighting device main body 10 at least.

In the projection illuminator according to the present invention having the above-described structure, when the light source 16 is caused to emit light, the light is reflected by the pair of reflectors 18 and 50, and the surrounding light transmitting portion 41. The brightness of the inside is increased, and the increased light is transmitted through the entire circumference of the surrounding light transmitting part and is projected to the outside world, giving the object around the outside environment decorative light. . In addition, the light having a light-transmitting character, animal, flower, or other desired design having various design characteristics applied to the envelope-shaped light-transmitting portion 41 is also projected on the external object. From this point as well, it gives a unique light decorative property to the external object. In addition, the surrounding light-transmitting portion 41 has a light-transmitting character, an animal, a flower, or a transparent, colored transparent, or light-transmittable material having a desired pattern having various other design characteristics. Even when a colored non-transparent film 49 or the like is attached to deal with it, similar to the above, a unique light decorative property is given to the external object. Further, since the light corresponding to the design is emitted from the projection opening having the design of the reflector 50 of the light projecting portion 40 to the outside with a certain directivity, for example, the light is projected from the enclosed light transmitting portion 41. Projects a pattern of the required shape with designability on the external object in the direction perpendicular to the projected direction of the emitted light,
It is possible to impart a unique light decoration property to the object in the orthogonal direction. In addition, a transparent, colored transparent, or light-transmissible color having a desired pattern having a light-transmitting character, animal, flower, or other various design characteristics is formed in the projection openings 54, 55. When a non-transparent film having a transparent property is attached to deal with the above, it is possible to give a more colorful and unique peculiar decorative property to the above-mentioned right-angled object. Further, the lighting device body 1
On the other hand, when the light-projecting section 40 is at least reduced and the enclosed light-transmitting section 41 is reduced and moved within a range in which it can be housed in the lighting apparatus main body 10, it is easily miniaturized, for example, as a flashlight only. Although it can be used, it can be used as a flashlight while brightening the surroundings of the user even when it is extended and moved.

An annular depth forming wall surface 51 is provided which is sandwiched and fixed between the lowermost portion (that is, the same direction as above) of 1 and the upper surface (inner surface) of the projecting frame 63 which annularly projects horizontally inward. There is. A flange 52, the outer diameter of which is at least approximately equal to the inner diameter of the inner surface of the annular side wall 61 of the design ring 60, is provided on the outermost lower side of the depth forming wall surface 51, and the surrounding light transmitting portion 41 and the design ring 60 are provided. It is more secure to. The depth forming wall surface 51 is formed as an inclined annular wall surface whose inner diameter becomes gradually smaller as it goes toward the light bulb 16, and from this viewpoint as well, consideration is given to the designability of the projection lighting apparatus. ing.

On the center side of the reflector 50, there is a cylindrical portion projecting downward (that is, in the same direction as described above) in an annular shape with a relatively small size, and it projects inward in a horizontal inward direction on the inner side of its tip side. A light projecting annular projection 53 is provided, and a circular light projecting opening (projection opening) is provided on the inner circumference of the light projecting annular projection 53 to project the light of the light bulb 16 to the outside with a certain directivity. ) 54 are formed.

The mask body 56 and, above all, the notched portion 55 for projecting a light are also provided with a colored or colorless pattern of the above-mentioned light-transmitting character or the like on the entire surface or at least a part thereof regardless of the front and back surfaces. Alternatively, a completely transparent, colored semi-transparent or transparent, or light-transmittable colored non-transparent film (not shown) may be attached.

It should be noted that, instead of the structure of the annular projection 53 for projecting light, a structure of one planar part having a notched part (projection opening) of a required pattern shape of the above character or the like may be adopted. In the example, in consideration of efficiently producing a plurality of types of projection illuminating devices according to the present invention having different projection aperture shapes, a replaceable mask body 56 is adopted at a low cost, which makes it possible to easily produce a plurality of types. It is possible to continue to cope with the needs of the market at a low cost in the production or production change of projection apertures.

The depth forming wall surface 5 of the reflector 50
Between 1 and the cylindrical portion (the light-projecting annular projection 53 side) projecting in an annular shape with a relatively small size below the center side, there is a so-called semi-doughnut shape (horizontal cut) as a whole. A ring-shaped curved surface that curves toward the outside of the ring (the side that faces the opposite direction from the light bulb 16) is configured. The curved surface of the reflector 50 reflects the light of the bulb 16 to the center side and the outside in the bulb 16 side direction and the reflector 18 side direction. Both reflectors 18 and 50 make more effective use of the light emitted from the light bulb 16 to enhance the intensity of light projected from the surrounding light transmitting portion 41 and the light-projecting pattern cutout portion (projection opening) 55 to the outside. The brightness can be improved.

On the other hand, as described above, the design ring 60

It is equipped with. A concave groove 62 is formed on the inner wall surface side of the side wall 61 for receiving the second locking projection 48 of the surrounding light transmitting portion 41, and the reflector 50 is formed on the innermost side of the lowermost side wall 61. The protrusion frame 63 is formed to have a size that is, for example, slightly larger than the size that allows the depth forming wall surface 51 to be completely accommodated, and that protrudes annularly inward horizontally. Transparent glass, resin, or the like may be mounted on the circular opening side formed on the inner circumference of the protrusion frame 63.

Next, an example of assembling and using the projection lighting device according to the present embodiment having the above-described structure will be described. As shown in FIG. 2, first, the lighting device main body 1
On the 0 side, wiring-related connections of the electric system are performed, the switch 15 and the socket 17 are assembled, and the bulb 17 is held in the socket 17. On the other hand, the reflector 18 is shown, for example, between the periphery of the reflector 18 and the inner circumference of the surrounding light transmitting portion 41 with respect to the inner side of the tip side of the surrounding light transmitting portion 41 on the first annular locking projection 43 side. Do not engage by engaging projections, screw-like screwing, or using press-fitting and adhesives, or any other known attachment method for a dedicated attachment member, and
The reflecting body 50 to which the mask body 56 is attached is housed in the annular projection 44 and the annular wall body 45 of the surrounding light transmitting portion 41, and the annular wall is outside the annular wall body 45 of the surrounding light transmitting portion 41.

After each of the second locking projections 48 is engaged in each of the recessed grooves 62, the triangular key-shaped portion of each of the second locking projections 48 is located on the upper surface of each of the recessed grooves 62. Since the engagement is continued, the design ring 60 cannot be pulled out from the surrounding light transmitting portion 41, and the assembling of both 41 and 60 is strongly maintained, and the assembling of the reflector 50 is also stable. It is possible to maintain. Thus, the assembling of the light projecting section 40 is completed by the above assembling.

In this state, the first annular locking projections 43 of the surrounding light transmitting portion 41 are connected to the annular projections 33 of the fixing ring 30.
The first annular locking projections 43 are housed in the step on the front end open side of the lighting device body 10 while being locked to each other, and the locking projections 32 of the fixing ring 30 are engaged with the engaged parts of the lighting device body 10. By engaging with the illuminating device 22, it is possible to maintain the assembling of the light projecting portion 40, that is, the enclosed light transmitting portion 41, with respect to the lighting device body 10. Then, the handle 21 is rotatably assembled to the two rotary shafts 20, 20 of the lighting device main body 10 and arranged in the battery accommodating portion 14 in accordance with a predetermined connection standard. When the battery 13 is housed and the battery housing 14 is closed by the battery lid 12, the assembly of the projection lighting device according to the present embodiment is completed.

Since the present invention is configured as described above, it is possible to increase the effective utilization rate of the light of the light source 16 and increase the brightness, and at the same time, to increase the brightness of the light around the light source 16. It is possible to project an object 71, 72 or the like in the outside world, including a colored or colorless pattern 74 of light such as a character, to enhance the decorativeness of the light around the light source 16 and in another direction in the outside world. Also, it is possible to enhance the decorative property of double light by projecting a colored or colorless pattern 75 of light such as a character having directivity to some extent.

That is, in the present invention, firstly, the surrounding light transmitting portion 41 surrounding the radial periphery of the light source 16 on the illumination device body 10 side and the periphery of the front of the light source 16 mounted on the illumination device body 10. This is because a pair of reflectors 18 and 50 are provided on both sides of the front end of the light projecting section 40 having the above-mentioned structure. This increases the brightness in the enclosed light transmitting section 41, and the increased light is surrounded by the enclosed light. Light can be projected from the transmissive portion 41 to the surroundings of the outside world, and as a result, the decoration of light can be given to the objects 71, 72 and the like in the outside world by this projection of light.

The surrounding light transmitting portion 41 has a required colored or colorless pattern 4 having a light transmitting character, animal, flower, or other various design characteristics.
Since 9a is applied, it is possible to project a colored or colorless pattern 74 of light that reflects the colored or colorless pattern 49a or the like to the surroundings of the external world, and from this point as well, it can be an object of the external world. A unique light decoration can be given.

In addition, a transparent or chromatic character is formed by forming a desired colored or colorless pattern 49a or the like having a light-transmitting character, animal, flower, or other various design characteristics with respect to the surrounding light-transmitting portion 41. Even when a transparent or light-transmitting colored non-transparent film 49 or the like is attached to deal with it, similar to the above, it is possible to impart a unique light decorative property to the external object.
