Description

[Detailed description of the invention] (a) Field of industrial application The present invention relates to a lantern lighting fixture with a built-in circular fluorescent lamp.

(b) Conventional technology Conventionally, when lanterns were used as lighting equipment, incandescent light bulbs were built into the lanterns.

(c) Problems that the invention aims to solve However, these days, circular fluorescent lamps, which are brighter than incandescent bulbs and consume less power, have become widespread.
There is a demand for a lantern lighting device with a built-in circular fluorescent lamp, but for spherical or ellipsoidal lanterns, a circular opening with an inner diameter large enough to insert a circular fluorescent lamp with a large outer diameter is required. If the hole is formed in the upper or lower part, the inner diameter of the circular hole will be too large compared to the overall size of the lantern, and this will inevitably hinder the appearance of the lantern as a whole. In the case of lanterns that are originally spherical or ellipsoidal, the current situation is that the dimensions of the circular openings in the upper or lower part of the lantern have a fixed ratio and are standardized. For example, in the case of a spherical lantern with a diameter of 48 cm, which is the most appropriate size, it is common to have a circular hole with an inner diameter of 18 cm at the top and a circular hole at the bottom with an inner diameter of 9 cm. In this case, although it is intended to incorporate a standard circular fluorescent lamp with an outer diameter of 22 cm into a spherical lantern of such dimensions, there is no opening large enough to insert the circular fluorescent lamp. For this reason, it has not been possible to manufacture a spherical or ellipsoidal lantern lighting fixture with a built-in circular fluorescent light.

The present invention was devised to solve the above-mentioned problems, and its purpose is to manufacture and provide a spherical or ellipsoidal lantern lighting device with a built-in circular fluorescent light.

(d) Means for solving the problems The present invention is based on forming the peripheral frame of a circular hole in a lantern of a spherical or ellipsoidal shape using a material that can be deformed by pressure, such as wire, and A circular fluorescent lamp having an outer diameter larger than the inner diameter is inserted vertically into the lantern by pressing and deforming the peripheral frame to make the circular hole elongated, and then inserting the circular fluorescent lamp vertically into the lantern, which has an outer diameter larger than the inner diameter of the circular hole. This lantern is characterized by a fluorescent light built into the lantern.

To explain this invention with reference to the drawings, 1 is split bamboo 2
It is a lantern made of a spherical or ellipsoidal lantern with a frame and paper 3 stretched over it, with a circular hole 4 formed in the upper part, and a peripheral frame 5 forming the periphery of the hole pressed and deformed with wire or the like. Formed from possible materials. Such a circular opening 4
When inserting a circular fluorescent lamp 6 having an outer diameter larger than the inner diameter of the circular aperture 4 into the lantern 1,
The circumferential frame 5 is once pressed and deformed to make the circular opening 4 oblong. A circular fluorescent lamp 6 is inserted vertically into the oval circular hole 4, and the circular fluorescent lamp 6 having an outer diameter larger than the inner diameter of the circular hole 4 is built into the lantern 1. .

In the figure, 7 is a cord stopper that is detachably engaged with the peripheral frame 5 of the circular opening 4, 8 is a support device for the circular fluorescent lamp 6, 9 is an electric cord, 10 is a rubber stopper ring,
Reference numeral 11 indicates a circular hole opened at the bottom of the lantern 1.

(E) Function To give an example of the dimensions of the lantern 1, the diameter is about 48 cm, the upper circular hole 4 has an inner diameter of 18 cm, and the lower circular hole 11 has an inner diameter of 9 cm. Now, when the circumferential frame 5 of the circular aperture 4 with an inner diameter of 18 cm is pressed from both sides, the circumferential frame 5 is made of a material that can be deformed by pressure, such as wire, so it deforms and the circular aperture 4 forms two points in FIG. As shown by the chain line, the original shape is broken and the shape becomes oval. When the circular hole 4 is elliptical, its long axis l dimension is 22
cm or more, so that a circular fluorescent lamp 6, which is a general standard product and has an outer diameter of about 22 cm, can be inserted vertically into the lantern 1 as shown in FIG. At the step where the circular fluorescent lamp 6 has been inserted into the lantern 1, the deformation of the peripheral frame 5 is corrected to restore the circular opening 4 to its original shape, and then the cord stopper 7 is engaged and passed to the peripheral frame 5. Thereby, the circular fluorescent lamp 6 having an outer diameter larger than the inner diameter of the circular aperture 4 can be built into the lantern 1.

(f) Effects As explained above, the present invention allows the circular fluorescent lamp 6 having an outer diameter larger than the inner diameter of the circular opening 4 to be built into the lantern 1, which was recognized as something that could not be produced conventionally. A lantern lighting fixture with a built-in circular fluorescent lamp can be easily manufactured and provided.
Moreover, since the circular fluorescent lamp 6, which is larger in size than the circular aperture 4, is built into the lantern 1, it also has the effect of arousing mysterious interest at first glance.
