Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a jewelery luminaire, particularly a jewelery luminaire suitable for illuminating diamonds. Note that the gemstones referred to in the present application include not only so-called bare stone gems but also gems attached to jewelry such as rings, necklaces, and broaches.

[0002]

[Prior art]

 One of the reasons diamonds are favored is their unique brilliance. The brilliance peculiar to this diamond is due to the fact that the light incident from the diamond surface is dispersed in the process of internal reflection at each cut surface, and this light returns to the diamond surface to appear as a brilliant color of various colors. is there.

Conventionally, a halogen lamp or the like has been used for illuminating diamonds displayed and sold in a store in order to effectively show the brilliance of the diamonds. However, simply illuminating the diamonds in the showcase cannot effectively show the glittering and colorful colors that are typical of diamonds. In other words, the brilliant and colorful color that is unique to diamonds is caused by the change in the intensity and direction of the reflected light from the diamond, and therefore when the diamond is in place, Unless the observer's direction of looking at the diamond is constantly changing, it does not look like the glittering state as described above.

[0004]

[Problems to be solved by the device]

 Therefore, in order to produce the above-mentioned brilliance peculiar to diamonds, a diamond may be placed on a turntable for display, but the turning mechanism used in this case is usually a structure built into a showcase. Therefore, there is a drawback that the equipment cost is high. In addition, only small items of jewelry can be displayed on the rotating table, let alone exhibits in combination with clothing (for example, clothes worn on a mannequin with the jewelry attached). It is possible.

In view of such conventional problems, the present invention can generate a beautiful sparkle that is peculiar to diamond without rotating the diamond itself, and is related to the size of the accessory and the display form. The present invention aims to provide a jewelry lighting fixture that can be used without any cost and can be manufactured at low cost.

[0006]

[Means for Solving the Problems]

 In order to achieve such an object, the luminaire of the present invention comprises a base part having a motor for rotating a lamp, a lamp holding arm extending from the base part, and a lamp holding arm. A lamp mounting portion rotatably held at the tip of the lamp, one or more lamps mounted at a position eccentric from the rotation center of the lamp mounting portion, and along the longitudinal direction inside the lamp holding arm. A cable body or a shaft body for power transmission, one end of which is connected to the drive shaft of a reduction mechanism attached to the motor or the motor and the other end of which is connected to the lamp mounting portion. It is a luminaire for jewelry such as diamonds.

[0007]

[Action]

 Illuminating a diamond (hereinafter, the case where the object of illumination is a diamond) with a lit lamp and driving the motor for driving the lamp rotation causes the cable body or shaft inside the lamp holding arm to rotate and the lamp to rotate. Rotate the mounting part. Due to the rotation of the lamp mounting portion, the lamp mounted at a position eccentric from the center of rotation rotates. The direction of the light that hits the diamond changes continuously due to the turning motion of this lamp. Therefore, when observed from a fixed position, the direction and intensity of the light reflected from the diamond changes continuously, which is characteristic of diamond. You can observe the glitter of various colors. In addition, by covering the sides of the lamp with a lamp shade to make the lamp invisible to the observer from the observer's side, the diamond itself appears to emit light that continuously changes, and the display is It can give the viewer a very impressive visual effect.

Further, in the device of the present invention, since the motor for driving the rotation of the lamp is provided in the base part, the lamp mounting part which is the illumination part is not bulky, and it is possible to have a small, lightweight and smart structure. Therefore, when used for a display, the illumination section is not conspicuous, and the above visual effect can be further enhanced in this respect as well.

【Example】

 FIG. 1 shows an embodiment in which the present invention is applied to a stand-type lighting fixture. Reference numeral 1 is a base portion provided with a motor for rotating a lamp, and 2 is an extension from the base portion. Lamp holding arm, 3 is a lamp mounting portion rotatably supported at the tip of the lamp holding arm, 4 is a lamp mounted on the lamp mounting portion, and 5 is power transmission provided in the lamp holding arm. It is a cable body for.

The base portion 1 constitutes a seat portion of a stand, and a motor 6 is housed inside thereof. The lamp holding arm 2 is composed of a flexible hollow tube made of metal or the like (for example, a bellows metal tube), and one end of the lamp holding arm 2 is connected to the base 1. A mounting base portion 9 for holding the lamp mounting portion is fixed to the other end thereof. A through hole 16 is provided in the center of the mounting base 9.

A shaft body 10 is provided at the center of the rear surface of the lamp mounting portion 3, and the shaft body 10 is rotatably fitted into the through hole 16 of the mounting base portion 9 to allow the front surface of the mounting base portion 9 to be attached. It is arranged to be freely rotatable. Two lamp sockets 13 are provided on the front surface of the lamp mounting portion 3, and the lamps 4 are mounted on the respective sockets 13. Each lamp 4 is located at a position eccentric from the rotation center of the lamp mounting portion 3. Further, an annular electrode rail 12 is provided on the back surface of the lamp mounting portion 3, and a current collecting brush 11 that is in contact with the electrode rail 12 by being biased by a spring is provided on the mounting base portion 9. Electricity is supplied to the orbiting lamp 4 by the electrode rail 12 and the current collecting brush 11.

The cable body 5 is rotatably arranged in a sheath tube 7 provided along the longitudinal direction inside the lamp holding arm 2, and one end thereof is attached to a drive shaft 61 of the motor 6 (or a motor). The drive shaft of the reduced speed mechanism) and the other end is connected to the shaft 10 of the lamp mounting portion 3. In the other drawings, 14 and 15 are lamp shades.

FIG. 2 shows another embodiment of the present invention, in which one lamp 4 is provided at a position eccentric from the rotation center of the lamp mounting portion 3. Since the other structures are the same as those of the embodiment shown in FIG. 1, the same reference numerals are given and the description thereof is omitted.

FIG. 3 shows an embodiment in which the present invention is applied to a hanging type lighting device. The base 1 is fixed to an appropriate fixed portion such as a ceiling, and the lamp mounting portion 3 is provided. And the lamp 4 are suspended and held via the lamp holding arm 2. Since the other structures are the same as those of the embodiment shown in FIG. 1, the same reference numerals are given and the description thereof is omitted. As shown in FIG. 3, when the lamp holding arm 2 is used only in a straight pipe state, the lamp holding arm 2 is a rigid pipe, and a shaft body for power transmission can be used instead of the cable body 5. .

Next, the operation of the apparatus of the above embodiment will be described with reference to FIG. 1, in which the lamp holding arm 2 is appropriately bent and the lit lamp 4 is directed toward the diamond to be illuminated. When the motor 6 in the base part 1 is driven, the cable body 5 for power transmission rotates inside the lamp holding arm 2 and the lamp mounting part 3 supported at the tip of the lamp holding arm 2 rotates. . As a result, each lamp 4 pivots around the rotation center of the lamp mounting portion 3. The direction of the light striking the diamond changes continuously due to the turning motion of this lamp. Therefore, when observing the diamond from a fixed position, the direction and intensity of the reflected light from the diamond changes continuously, and You can observe the brilliance of various glittering colors.
