  Candles could be ignited, and light bulbs consumed large amounts of electricity, both of which had a short life. Moreover, since it is a light source from one direction, it was an inefficient lighting fixture. In the present invention, it is an object to solve the problems of the prior art.

  LED is used as the illuminant to be attached to the inside of the vessel, and a conical reflector is provided on the inside of the lid, a plurality of the reflectors are overlapped to form a foldable reflection, and a bellows fold is formed in the translucent film. The most important feature is that the light-transmitting film is a bellows cylinder that can be fixed in a deeply bellows-folded state.

  By using LED as the illuminant, the electricity consumption is reduced and the service life is extended, and by providing the reflector, the brightness is doubled. As a result, the whole can be stored in a small size, and the bellows tube can be fixed in a deeply bellows-folded state, so that there is an advantage that the contracted state can be maintained without fitting and fixing the vessel and the lid.

FIG. 1 is a simplified cross-sectional right side view of an essential part of the stretched state. Example 1 FIG. 2 is a simplified cross-sectional right side view of the main part in the contracted state. FIG. 3 is a right side view of the stretched state. FIG. 4 is a front perspective view of the stretched state. FIG. 5 is a reflection continuous perspective view in an extended state.

  We have realized a lantern lantern that can save energy, has a long life, is efficiently bright, and can be stored compactly.

  FIG. 1 is a simplified right side cross-sectional view of an essential part of the stretched state, and a dish-shaped vessel 1 having an outer ring wall 8 whose peripheral edge of the central plane area 12 is raised, and an outer ring wall 8 around the central plane area 12 as described above. And a lid 2 having substantially the same size and shape in a positional relationship with respect to the surface of the ceiling, the container 1 is positioned at the bottom, the lid 2 is positioned at the top, and the outer peripheries of the plane area 12 between the container 1 and the lid 2 The translucent film 3 is provided in a cylindrical shape connecting the two. The translucent film 3 may be formed by winding a flat sheet into a cylindrical shape, but it is desirable that the translucent film 3 has a bellows-folded cylindrical shape in which mountain folds and valley folds are alternately repeated in parallel with the winding direction.

  The light emitter 4 installed inside the container 1 may be a miniature light bulb, but is preferably an LED, and hereinafter the light emitter 4 is an LED. Although the number of the light emitters 4 may be singular, a plurality of them are desirable, and the arrangement is not limited, but it is desirable to arrange them in a circle. The number is not limited, and it may be changed to an arbitrary number to obtain an arbitrary brightness. 6 to 8 are shown as desirable numbers. The light emitters 4 are fixed in a circular pattern on a substrate 9 with wiring on the lower surface. A chamber is provided under the substrate 9 to store a battery 10, and the battery 10 serves as a power source for illuminating the light emitter 4. . A headed pin 11 is provided on the front surface of the outer ring wall 8 of the vessel 1, and the headed pin 11 also serves as an on / off switch for illuminating the light-emitting body 4 in addition to the role of fixing through the hem of the translucent film 3. To do.

  The material of the reflector 5 installed inside the lid 2 is not limited, and any material that reflects light may be used. Among them, a material with metallic luster is desirable, and aluminum or stainless steel is desirable for the metallic luster material. The shape of the reflector 5 may be a flat plate, but it is desirable that the reflector 5 be a cone as a structure that efficiently reflects the light-transmitting film 3 located obliquely below. Although the reflector 5 may be a single body, it is desirable that the reflector 5 be a reflection series 7 that can be expanded and contracted. The structure in which the plurality of reflectors 5 are connected to form the reflection series 7 is not limited. However, if a desirable structure is described, overlapping edges 15 are provided between adjacent edges of the conical reflecting surface 14, and the overlapping edges are formed. Since the fifteen members close each other, the reflectors 5 of the reflecting reed 7 in the stretched state cannot come out and come off. The reflection ream 7 may have a structure that expands and contracts by its own weight, but is preferably a structure that expands and contracts by the auxiliary force of the stretchable body 13 provided in the reflection ream 7. The material and structure of the stretchable body 13 are not limited, but a coil spring is desirable. The fixing of the upper edge of the translucent film 3 is not limited, but it is preferable that the light transmitting film 3 is fixed by being sandwiched by the innermost edge of the lid 2 at the outermost peripheral edge of the reflection ream 7.

  FIG. 2 is a simplified right side cross-sectional view of the main part of the contracted state. The light-transmitting film 3 is contracted by bending the bellows-folded portion 6 of the light-transmitting film 3 deeply into a bellows shape. The lid 2 approaches and the whole is retracted in a small size. The contracted state may be maintained by fitting the outer ring wall 8 between the vessel 1 and the lid 2, but a bellows fold fixing structure in which the bellows fold portion 6 of the translucent film 3 is bent deeply and fixed is desirable. The bellows fold fixing structure is a conventional technique, but the fixed state is maintained by tilting the bending direction of the bellows fold in one direction (inclining in the heaven direction in the drawing).

  The structure in which the reflection series 7 contracts is performed by separating the overlapping edges 15 from each other. Since the light emitters 4 are arranged in a circle, the tip region of the central portion of the reflection ream 7 is housed in the central portion of the circle, and the reflex ream 7 can be contracted while avoiding the light emitter 4 skillfully. The expansion / contraction body 13 is also contracted by the contraction of the reflection ream 7, and the force for the expansion / contraction body 13 to extend is suppressed.

  FIG. 3 is a right side view of the stretched state. When the angle of refraction of the bellows fold portion 6 becomes approximately 90 degrees, the cylindrical light-transmitting film 3 is stretched, and the vessel 1 and the lid 2 are separated. . The front surface of the outer ring wall 8 of the container 1 partially protrudes, and the protruding portion is a storage location for the headed pin 11. It is desirable to provide a handle 16 on the outer ring wall 8 of the lid 2, and a mounting portion of the handle 16 is preferably a rotatable rotating portion 17.

  FIG. 4 is a front perspective view in an extended state. A headed pin 11 is housed in the front portion of the outer ring wall 8 of the vessel 1, and the headed pin 11 functions as a switch for fixing the hem of the translucent film 3 and a switch. Fulfill. The lid 2 is fixed to the translucent film 3 so as to be able to rotate and slide. A tape-like handle 16 is attached to the outer ring wall 8 of the lid 2 in an arched semicircular shape via a rotating portion 17, and one edge of the outer ring wall 8 of the lid 2 protrudes appropriately to form a convex edge 18. The convex edge 18 serves as a blocking edge of the handle 16 accommodated in a state of being tilted horizontally. The plane area 12 which is the central area between the container 1 and the lid 2 is preferably circular.

  FIG. 5 is a perspective view of the extended reflection series, and the reflection series 7 is an assembly in which a plurality of reflectors 5 are continuously connected. The basic shape of the reflector 5 is a cone, and the inclined surface of the cone is a reflecting surface 14, and the region where the edge of the cone is refracted by a metal diaphragm is an overlapping edge 15. Since the overlapping edges 15 are fixed in a blocked state, the reflectors 5 of the reflection series 7 in an extended state are not separated. The number of the reflectors 5 that form the reflection series 7 is not limited, but it is desirable that the number of the reflectors 5 be three to form one reflection series 7.

  Although the present invention is portable, it can also be applied to stationary applications.
