Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a lighting device that scatters light on a ceiling or a wall surface in a room, and more particularly to a lighting device that can increase the number of spots of scattered light and complicate movement with a simple structure.

[0002]

[Prior art]

 One of the lighting devices is a lighting device marketed by the applicant as "Music Light AT-747". In this illumination, multiple lenses are arranged on the surface of the hollow shell of the sphere, and the light from the lamp provided inside is emitted through these lenses to the outside to form a large number of beam spots. The beam spot is designed to move by rotating the hollow shell. This causes the beam spot to scatter into the room and move a number of inversions of light to the walls, floor and ceiling of the room. In this lighting system, when the light from the light source is projected as a beam spot, the rotation axis of the hollow shell is rotated by one axis, so the movement of the spot is monotonous, and if you want to complicate the movement of the spot. Requires the rotation axis to be set to 2 or 3 axes.

[0003]

[Problems to be solved by the device]

 By the way, if the rotation axis is two or three axes in order to complicate the spot, not only the mechanism becomes complicated but also the power supply to the light source becomes difficult.

The present invention has been made in view of the circumstances of the prior art as described above, and an object thereof is to provide an illuminating device capable of moving a variety of complex spots with a simple configuration.

[0005]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the present invention provides a lamp that emits light when energized, a shell body having a plurality of lenses for diffusing the light of the lamp to an external space, and a shell body provided in the shell body so that the lamp emits The light reflection means reflects the reflected light and diffuses the light from the lens of the shell body to the external space, and the driving means rotates and drives one of the shell body and the light reflection means.

[0006]

[Action]

 According to the above-mentioned means, in addition to the direct light from the lamp passing through the lens and being scattered as spot light by the rotation of the shell body, the reflected light reflected by the reflecting means such as a reflecting mirror is also made into spot light. Is scattered through. This not only increases the number of spot lights simply by rotating the shell body or the light reflection means, but also makes it possible to diversify the spot light scattered according to the relative position change between the direct light and the reflected light and the shell body. Can be changed to.

【Example】

 An embodiment of the present invention shown in the drawings will be described below. FIG. 1 is a side view showing a part of a lighting device according to this embodiment in cross section, FIG. 2 is a plan view showing a state where the shell body is removed, and FIG. FIG. 4 is a side view showing a cross section of FIG.

In these figures, a lighting device 1 is composed of a base 2 made of a synthetic resin or the like in the shape of a bottomed cylindrical body, and a metal sheet metal attached to the upper portion of the base 2. The mounting base 3, a reflector device 4 attached to the lower part of the center of the attachment base 3, a lamp 5 as a light source located in the reflector device 4, and a base 2 having a hemispherical upper surface. A shell body 6 that is detachably fitted so as to cover the shell 6, a large number of lenses 7 that are fitted over the entire curved surface of the shell body 6, and a drive means 8 that rotationally drives the shell body 6. Is configured.

As shown in FIG. 2, the reflector plate device 4 includes four planar reflector plates 4 a, 4 b, 4 c, which are arranged so as to surround the lamp 5 and are inclined with respect to the mounting base 3. It is composed of 4d.

The drive mechanism 8 is a motor 9 provided above the mounting base 3 in FIG. 2, a worm gear 10 axially attached to the rotation shaft of the motor 9, and a worm wheel meshing with the worm gear 10. Of the intermediate gear 11, the inner toothed ring member 12 having an inner toothed gear that meshes with the intermediate gear 11 on the inner peripheral surface thereof, and the rib 16 erected substantially in the center of the upper surface of the inner toothed ring member 12. Mainly consisting of three auxiliary wheels 13a, 13b, 13c that roll and contact to regulate the vertical movement of the shell body 6 and a pressing arm 14 that presses one of these auxiliary wheels 13a outward in the radial direction. It is configured. A rubber ring 15 is fitted on the outer peripheral portion of each auxiliary vehicle 13a, 13b, 13c, and the rubber ring 15 is in direct contact with the rib 16. The pressing arm 14 is swingably supported with a support shaft 19 as a fulcrum, and is elastically biased by a tension coil spring 17 in a direction to constantly press the auxiliary vehicle 13a against the rib 16, and the remaining two auxiliary vehicles 13b and 13c. The position of the internal tooth ring member 12 is determined by cooperating. As a result, the intermediate gear 11 is used only for driving the inner toothed ring member 12 and does not participate in positioning. The pressing arm 14 also has a function of keeping the amount of meshing between the inner toothed ring member 12 and the intermediate gear 11 constant. The internal tooth ring member 12 can be rotated by the fixtures 18 at three points, but its movement in the vertical direction is restricted.

As shown in FIGS. 1 and 3, the shell body 6 is fixed to the base 2 by fitting the outer peripheral edge of the internal tooth ring member 12 into the lower opening thereof. As a result, the shell body 6 also rotates due to the rotation of the inner tooth ring member 12.

In the illumination device 1 having the above-described structure, when the motor 9 is turned on to rotate the motor 9, the rotational driving force is transmitted from the worm gear 10 to the internal gear ring member 12 via the intermediate gear 11. To be done. As a result, the shell body 6 also rotates. On the other hand, when the motor 9 is turned on, the lamp 5 is also energized and the lamp 5 emits light. Due to the light emission of the lamp 5, the direct light from the lamp 5 is incident on all the lenses 7, and the spot of the direct light is projected to the outside. Further, the light of the lamp 5 is reflected by the four reflectors 4a, 4b, 4c, 4d of the reflector device 4, and these reflected lights are also projected to the outside from the lens 7 located in the reflected light path. The reflected light is three reflections reflected by three reflection plates 4a, 4b, 4c, and 4d, excluding one reflection plate whose back surface faces the corresponding lens 7. Light will be incident at maximum. Therefore, depending on the corresponding lens 7, the direct light and the reflected light from the three reflecting plates are incident at different angles, and four light spots are generated from one lens 7. Further, in the other lenses 7, three or two light spots are projected depending on the angles at which the reflection plates 4a, 4b, 4c and 4d are located. On the other hand, since the shell body 6 rotates as described above, this rotation changes the relative positional relationship between the lens 7 and the lamp 5 and each of the reflectors 4a, 4b, 4c and 4d, so that the incident angle is also changed. It changes according to the relative position change, and further, the emission angle from the lens 7 naturally changes, which makes the movement of the spot scattered in the room very complicated and diversified.

Although the shell body 6 is rotated in the above-described embodiment, the shell body 6 is fixed to the base 2 and the reflecting device 4 is rotatably supported by the mounting base 3 to allow the reflecting device 4 to rotate. May be rotated. If the movement of the spot is desired to be further varied, the shell body 6 and the reflecting device 4 may be rotated. In this case, since it suffices to add a rotation drive mechanism for the reflection plate 4, the mechanism does not become complicated as when introducing a biaxial or triaxial mechanism. Further, the number of spots can be appropriately set by changing the number of the reflection plates 4, and the reflection plates 4 may be provided in multiple stages, the angles of the respective reflection plates 4 may be changed, or curved surfaces may be formed. Variations can be considered.

With a simple structure, it is possible to move complex spots.
