2. Description of the Related Art One of the reasons why diamond is preferred is
It has a unique shine. The brilliance peculiar to this diamond is due to the fact that the light incident from the surface of the diamond is dispersed in the process of internal reflection at each cut surface, and this light returns to the surface of the diamond to appear as a brilliant color of various colors. .

Conventionally, a halogen lamp or the like is 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 colorful colors peculiar to the diamonds. In other words, the brilliant and colorful color shining peculiar to diamond occurs because the intensity and direction of the reflected light from the diamond changes with respect to the observer, and therefore, when the diamond is in place, Unless the direction of looking at the diamond is constantly changing, it does not look like the glittering state as described above.

[0004]

Therefore, in order to generate the above-mentioned brilliance peculiar to diamonds, the diamonds may be mounted on a turntable and displayed, and the turning mechanism used in this case is usually a show. Since the structure is built into the case, there is a drawback that the equipment cost is high. Moreover, only relatively small accessories can be displayed on the turntable, and it is almost impossible to display them in a state in which they are combined with clothes (for example, the costume worn on the mannequin is attached to the accessory). is there.

In view of such conventional problems, the present invention can generate a beautiful sparkle peculiar to a diamond without rotating the diamond itself, and regardless of the size of the jewelry and the display form. It is an object of the present invention to provide a jewelry luminaire that can be used and can be manufactured at low cost.

[0006]

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

[0007]

[Function] When a lamp is illuminated to illuminate a diamond (hereinafter, the case where the object of illumination is a diamond is described) and a motor for driving the rotation of the lamp is driven, a cable body or a shaft body inside the lamp holding arm rotates. Rotate the lamp mount. 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 colorful colors. In addition, by covering the side of the lamp with a lamp shade to hide the lamp that makes a turning motion from the observer's side, the diamond itself appears to emit light that continuously changes, and the display is viewed. It is possible to give a person 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 portion, the lamp mounting portion as the illuminating portion 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.
