2. Description of the Related Art As a lamp using the light emitting diode as described above, for example, utility model registration No. 3035678.
A lamp for a lantern described in Japanese Patent Publication is known. Conventionally, an incandescent light bulb has been used as a lamp for a lantern. However, when using an incandescent light bulb, there are problems such as causing a problem of heat generation due to long-term use and a short life of the light bulb. Therefore, by adopting a light emitting diode as a light source, safety and life can be significantly improved as compared with an incandescent light bulb.

By the way, generally, in a space where a serious atmosphere such as a religious ceremony is emphasized, it is extremely important to determine the suitability of the light source color of the lamp. However, since the light-emitting diodes that make up the lamps described in the above publications have only one color, they are often too bright or have an unnatural color depending on the application, and a light source color suitable for the application is obtained. It was often difficult.

[0004]

In view of the above-mentioned conventional circumstances, the object of the present invention is to provide a safe and long service life, and
It is to provide a lamp having a light source color suitable for the intended use.

[0005]

In order to achieve the above object, the lamp according to the present invention is characterized by a plurality of light emitting diodes, a substrate on which these light emitting diodes are arranged, and a periphery of these light emitting diodes. And a translucent cover that is translucent or milky white. Further, these light emitting diodes are composed of at least two colors, and two or more second color light emitting diodes are arranged so as to surround the first color light emitting diode.

It is desirable that the light emitting color of the second color light emitting diode is closer to the orange system than the light emitting color of the first color light emitting diode.

By fixing the substrate to a screw type base, it can be used as a substitute for an existing incandescent lamp. Further, a light scatterer may be provided between the cover and the light emitting diode.

It is desirable that the light-scattering body is in the form of a film and that a saliva portion is provided between the substrate and the light-scattering body.

By the way, when the lamp is provided with a screw base, when the lamp is turned on in a lantern or the like, a shadow of the base portion may be formed to impair the appearance. In such a case, it is preferable that a mounting tool is provided for sandwiching and mounting the board together with the cover, and an electric wire for supplying electric power to the board is pulled out through the mounting tool. Thereby, the light can be turned on without worrying about the shadow of the base portion.

In addition, the side portion of the fixture may be configured so that the light from the light emitting diode is emitted in the plane direction of the substrate, and is particularly suitable for a lantern.

A lamp having any of the above features is particularly suitable for use in religious ceremonies such as Buddhist altars, altars, lanterns, temples and churches.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Next, referring to the attached drawings,
The present invention will be described in more detail. In the first embodiment shown in FIGS. 1 to 3, a lamp 10 for a lantern 1 which is suspended from a Buddhist altar and used will be described. This lantern 1 is roughly composed of a lantern cover 2, a hanging pipe 3 for hanging the lantern cover 2 on the ceiling of a Buddhist altar, a socket 4 provided at an end of the hanging pipe 3, and an inside of the lantern cover 2. And a lamp 10 suspended from and supported by the socket 4.
It has and. Then, an electric wire penetrates into the cavity 3a formed inside the suspension pipe 3, and a current stepped down by a transformer from a commercial power source is supplied to the lamp 10 through the electric wire.

The lamp 10, as shown in FIG.
The base 11, the diameter-expanding member 12, the substrate 13, the light-emitting diode 14, the light-scattering body 15, and the cover 16 are provided, and as a whole imitates an incandescent light bulb that emits light by heating a filament. The outer surface of the base 11 is formed into a screw-shaped portion 11a. By screwing the base 11 into the socket 4, the lamp 10 is fixedly arranged inside the lantern cover 2 and necessary for lighting the light emitting diode 14. Supply current.

The diameter-expanding member 12 has a substrate 13 on the base of the base 11.
And is provided with a fitting portion 12a for fitting with the mouthpiece 11, an enlarged diameter portion 12b, and a saliva portion 12c. Then, the substrate 13 on which a plurality of light emitting diodes 14 serving as light sources are attached is arranged on the expanded diameter portion 12b, and the substrate 13 and the light emitting diode 14 are surrounded by the saliva portion 12c. In FIG. 3, the internal circuit is not shown, and a voltage is applied between the lower electrode 11b and the periphery of the base 11.

In the present embodiment, the light emitting diode 14 is
It is composed of two colors, a green diode 14a that emits G as the three primary colors and an orange diode 14b that emits orange, and a light source color such as candle light suitable for a lantern is obtained by additive color mixing. In particular, the green diode 14a is arranged in the central portion of the substrate 13, and the four orange diodes 14b are arranged in a rectangular shape in plan view so as to uniformly surround the periphery of the green diode 14a. With this arrangement, the green light emitted from the orange diode 14b is prevented from being directly viewed by itself from the outside, and a color mixture suitable for a Buddhist altar is obtained.

The light scatterer 15 is for mixing and diffusing the light emitted from the green diode 14a and the orange diode 14b. As a material of the light scatterer 15,
Although a milky white and translucent material is used, the light may be diffused in a two-dimensional direction by fine irregularities. The disk-shaped light scatterer 15 is placed on the upper surface of the saliva portion 12c and completely covers the opening of the diameter expanding member 12.

A fitting portion 16a of the cover 16 is fitted to the outer periphery of the saliva portion 12c, and holds and fixes the light scatterer 15 between the step 16b and the upper surface of the saliva portion 12c. This cover 16
Is made of milky white translucent resin and further diffuses and mixes the light of the light emitting diode 14.

With the above structure, the lamp 10 is viewed from above T.
Then, the green diode 1 is formed by the light scatterer 15 and the cover 16.
The light of 4a and the orange diode 14b are sufficiently mixed. Further, since the light emitting diode 14 is covered by the saliva portion 12c and the light scatterer 15 and the green diode 14a is surrounded by the plurality of orange diodes 14b, the monochromatic light of the green diode 14a is also seen in the side view S of the lamp 10. The light of the orange diode 14b is mixed or covered with the light of the orange diode 14b without leaking to the outside.

Next, a second embodiment according to the present invention will be described with reference to FIGS. Note that members having the same meaning as in the previous embodiment are denoted by the same reference numerals, and mainly different points from the above embodiment will be described. As shown in FIG. 4, the present embodiment relates to a lamp 10 used in a candle-shaped electric lamp 5 used by being arranged in a Buddhist altar.
The electric lamp 5 includes a Japanese candle-shaped stand 6 and a lamp 10 having a cover 17 that is screwed onto the stand 6 and imitates a flame.

As shown in FIGS. 5 and 6, the lamp 10 is generally provided with a base 11, a substrate 13, a light emitting diode 14, a light scatterer 15, and a cover 17. In the present embodiment, the cover 17 is modeled as a candle flame, so that the diameter of each member is formed to be smaller than that in the previous embodiment. Further, in the present embodiment, the fitting portion 17a of the cover 17 is provided on the upper portion of the base 11.
Is fitted inside, and the base 1 is attached to the step 17b formed in the fitting portion 17a.
The projecting portion 11c formed on the inner surface of the opening 1 is locked to couple the both. The substrate 13, the light emitting diode 14, and the light scatterer 15 are arranged in the base 11, and the base 11 prevents the green diode 14a from leaking to the outside as monochromatic light like the saliva portion 12c. In order to reduce the diameter of the substrate 13, one green diode 14a is sandwiched between two orange diodes 14b so that the green diode 1
4a and orange diodes 14b are arranged in a line.

Next, a third embodiment of the present invention will be described with reference to FIGS. In this embodiment,
As shown in FIG. 7, as in the first embodiment, the present invention relates to a lamp 10 for a lantern 1 that is hung from a Buddhist altar and used. This is different from the first embodiment in which the base 11 is screwed into the socket 4 in that the electric wire (cord) is directly drawn out from the substrate.

The lamp 10, as shown in FIG.
The mounting fixture 20, the substrate 13, the light emitting diode 14, the light scatterer 15, and the cover 16 are provided, and the model as a whole imitates an incandescent light bulb that emits light by heating the filament. In addition, the pair of tips of the cord 21 are directly soldered to the substrate 13, and the lead-out hole 2 provided in the fixture 20 is provided.
It is pulled out from 0a. The lamp 10 is pulled up above the inside of the cover 2 by a cord 21 penetrating the suspension pipe 3 so as to be close to the support plate 2a. Then, the connector 22, which is the tip of the cord 21, is connected to the external power supply.

As shown in FIG. 9, the fixture 20 is a substrate 1
An opening 2 for attaching the light-scattering body 15 and the cover 16 to 3 and having an extraction hole 20a for extracting all the cords connected to the substrate 13 in a bundled state.
The shape is almost the same as the diameter expansion member 12 in the first embodiment except that it has 0b. According to this structure, since there is no socket above the substrate 13, a shadow is less likely to be formed and an excellent appearance is exhibited as compared with the case where a conventional socket is provided when lighted.

Further, the opening 20 which constitutes the fixture 20.
b, the flat surface portion 20c and the side portion 20d are all made of a translucent or milky white translucent material. as a result,
The light emitted from the diode 14 is also emitted in the plane direction of the substrate 13. The light in the plane direction of the substrate 13 may not be sufficiently mixed with orange and green. However, since the lamp 10 is close to the support plate 2a, the amount of light that leaks is small, and because the cover 2 is covered with Japanese paper or a milky white plate, the color mixture of orange and green is less noticeable.

Finally, still another embodiment of the present invention will be described. In each of the above embodiments, the lamp according to the present invention is used for a lantern of a Buddhist altar or for a lamp stand simulating a candle. However, the lamp is not limited to these, and may be used as a lamp for religious ceremonies such as altars, temples, and churches. Also, it is suitable not only for religious purposes but also for places where the atmosphere of the space is important, such as theme parks and restaurants.

In the above embodiment, when the light emitting diode 14 is arranged on the substrate 13, one green diode 1
Although the two or four orange diodes 14b are arranged around 4a, the three orange diodes 14b are arranged in an equilateral triangle, or five or more orange diodes 14 are arranged.
b may be evenly arranged around the green diode 14a. Alternatively, a plurality of green diodes 14a may be provided and these may be surrounded by the orange diode 14b.

In general, when simulating a flame or a bulb light, it is unnatural that the green (G) of the green diode 14a leaks in a single color, so it is desirable to surround the green diode 14a with an orange diode 14b of orange. . Further, a plurality of diodes of at least two colors may be combined and used according to the purpose of use. Even when a light emitting diode other than orange or green is used, the light emitting color of the second color surrounding light emitting diode is closer to the orange system than the light emitting color of the first color light emitting diode located in the center. It is desirable, but not limited to this, if the lighting does not destroy the atmosphere.

[0028]

As described above, according to the features of the lamp according to the present invention, by combining the diodes of two or more colors, it is possible to obtain a light source color which is safe and has a long life and which is suitable for the intended use. it can. Moreover, by surrounding the light emitting diode of the first color with the light emitting diode of the second color, it is possible to obtain light in a good atmosphere without leaking monochromatic light.
