In this ceiling light, the sliding member is fixed to the outer cylindrical body, and the sliding member is provided with a protruding portion projecting outward, so that one of a pair of leaf springs abuts on the protruding portion. I have to. Thus, when the outer cylinder is rotated in the lateral direction with respect to the frame, the outer cylinder cannot be rotated more than 360 degrees, that is, more than one rotation.

As a result, the outer cylinder cannot be rotated many times in the same direction with respect to the frame.
If the outer cylinder is rotated 360 degrees in a certain direction, the next rotation of the outer cylinder will be 360 degrees in a direction opposite to the certain direction. In addition, by rotating the electric wiring many times in the same direction, an accident such as breaking a joint between the electric wiring and the socket or cutting off the electric wiring does not occur.

According to a seventh aspect of the present invention, there is provided a ceiling-mounted lamp according to any one of the first to sixth aspects, wherein a heat-dissipating plate is provided at the top of the inner cylinder body. In this ceiling-mounted lamp, since the heat sink is provided at the top of the inner cylinder, the outer cylinder is less likely to become hot.

And a ceiling-mounted lamp that is used to mount an illumination lamp on a socket provided in the inner cylinder, and that is used by embedding the outer cylinder in the ceiling, wherein the inner cylinder is formed inside the outer cylinder. The protrusion provided at a predetermined position on the peripheral side surface is supported by a cantilever structure so as to be rotatable in the vertical direction, and the shape of the inner cylinder is rapidly narrowed down toward the zenith. It is characterized by having a shape.

The ceiling-mounted lamp has a simple structure in which the inner cylinder is provided in a cantilever structure on the inner peripheral side surface of the outer cylinder so as to be rotatable in the vertical direction. As a result, the number of parts can be reduced, so that the manufacturing cost can be reduced and the assembling process can be simplified. Further, when changing the illumination direction, the side of the lower end of the inner cylinder facing the portion where the cantilever structure is provided can be easily pulled out from the outer cylinder.

In addition, in this ceiling-mounted lamp, since the outer cylinder is rotatably provided with respect to the frame, the lower end of the inner cylinder pulled out of the outer cylinder is held by a finger or the like, so that the inner cylinder is held. The body can be easily rotated. Furthermore, in this ceiling recessed light, as the shape of the inner cylinder body moves toward the zenith,
Since the shape is sharply narrowed down, the inner cylinder does not collide with the outer cylinder even if the inner cylinder is swung around the cantilever structure in the outer cylinder.

Thus, the inner cylinder can be swung large. In the ceiling-embedded lamp according to claim 9, a substantially equilateral triangular radiator plate is attached to an upper portion of the frame body, and a vertex of each of the substantially equilateral triangular radiator plates is provided on an outer peripheral side surface of the outer cylindrical body. It is characterized in that three leaf springs are provided so as to be aligned. In this ceiling light, a leaf spring is provided on the outer peripheral side surface of the frame, and the ceiling light is attached to a hole provided in the ceiling by using the elastic force of the leaf spring. The work can be performed very easily.

Further, since the shape of the heat radiating plate is substantially an equilateral triangle, the area of the heat radiating plate can be made large, and the heat in the frame can be increased with a large gap between the frame and the heat radiating plate. Thereby, the heat generated by lighting the illumination lamp can be efficiently released from the heat sink and the gap between the frame and the heat sink. Therefore, in the ceiling recessed lamp, even when the illumination lamp is turned on, the temperature of the frame body does not easily rise.

Also, since the three leaf springs are aligned with the vertices of the substantially equilateral triangular radiator plate, when viewed in plan, the circular pattern formed by the frame and the like and the triangle formed by the radiator plate. Since the pattern and the radiation-like pattern formed by the three leaf springs are fused, the appearance is excellent. A ceiling-mounted lamp according to a tenth aspect is characterized in that the center of the inner cylinder is shifted from the center of the outer cylinder in the ceiling-mounted lamp according to any one of the first to ninth aspects.

In this ceiling-mounted lamp, the center of the inner cylinder is provided at a position (eccentric position) shifted from the center of the outer cylinder. When looking up at the embedded lamp, the lower frame and the like of the inner cylinder are shifted from a plurality of concentric patterns constituted by the lower frame of the frame and the outer cylinder. Since the viewer recognizes this as a change in balance, the ceiling light is excellent in aesthetic appearance.

It should be noted that the center of the inner cylinder is located at the center of the outer cylinder,
When the projection is provided on the far side from the position of the projection provided at a predetermined position on the inner peripheral side surface of the outer cylinder, when the opening of the inner cylinder is oriented in the direction of the projection, the inner cylinder is pulled out of the outer cylinder. Since it is difficult to collide with the body, even when the illumination direction is directed to the projection direction, the inner cylinder can be swung largely.

The inner cylinder 4 is supported by a protrusion p3 provided at a predetermined position on the inner peripheral side surface of the outer cylinder 3 so as to be rotatable in the vertical direction in a cantilever structure. More specifically, the inner cylindrical body 4 has a protrusion p4 on the outer peripheral side surface at a position corresponding to the protrusion p3 provided at a predetermined position on the inner peripheral side surface of the outer cylindrical body 3.

In this example, the projections p3 and p
4 are provided with bolt insertion holes (not shown), bolts v are inserted into these bolt insertion holes (not shown), and then bolts v are screwed into nuts n. In this case, if necessary, a washer (not shown) may be interposed between the bolt v and the projection p3 and / or between the projection p4 and the nut n.

When the inner cylinder 4 supported by the cantilever structure is moved in the vertical direction on the side opposite to the position where the projection p3 is provided, the outer cylinder 3 Notched so that it does not hit body 3. More specifically, in this example, as shown in FIGS. 2 and 5, from the side where the projection p3 of the outer cylinder body 3 is provided, to the side facing the side where the projection p3 of the outer cylinder body is provided, The outer cylinder 3 is cut off diagonally downward.

In this example, taking advantage of this advantage, a hemispherical lamp having a reflecting mirror in the lamp L and having a large tip eL is attached as the illumination lamp L as shown in FIG. This eliminates the need for the reflecting cylinder 107 provided in the conventional ceiling embedded lamp 101 and the like shown in FIG. Further, in the ceiling-embedded lamp 1, as shown in FIG. 5, when the inner cylinder 4 faces directly below, the distal end e4a of the inner cylinder operation section 4c of the inner cylinder 4 is formed.
Is accommodated inside the lower end of the frame 2, so that when the inner cylinder 4 faces directly below, the tip e <b> 4 a of the inner cylinder operating section 4 c of the inner cylinder 4 is Does not protrude from the lower end of the.

As a result, the ceiling embedded lamp 1 is excellent in aesthetic appearance when the inner cylinder body 4 is facing directly below. Further, in the ceiling embedded lamp 1, since the sliding member 7 is provided between the outer cylinder 3 and the frame 2,
The outer cylinder 3 can be smoothly and laterally rotated.

Further, in the ceiling embedded lamp 1, the leaf springs 5a and 5b are provided on the outer peripheral side surface of the outer cylindrical body 3, and the holes provided in the ceiling are provided by using the elastic force of the leaf springs 5a and 5b. Since the recessed lamp can be mounted, the work of mounting on the ceiling can be performed extremely easily. Furthermore, in this ceiling embedded lamp 1, one of the sliding members 7
a is fixed to the outer cylindrical body 3, and the sliding member 7a is provided with a protruding portion p7 protruding outward, and one of a pair of leaf springs 5a, 5b abuts on the protruding portion p7. I have.

Thus, when the outer cylinder 3 is rotated in the horizontal direction with respect to the frame 2, it cannot be rotated by more than 360 degrees. As a result, the outer cylinder 3 cannot be rotated many times in the same direction with respect to the frame 2, and if the outer cylinder 3 is first rotated 360 degrees in a certain direction, Rotation of the outer cylinder 3 is performed in a direction opposite to a certain direction.
For example, when the electrical wiring W is provided on the socket S, the electrical wiring W is rotated many times in the same direction, for example, when the electrical wiring W is provided on the socket S, so that the electrical connection between the electrical wiring W and the socket S is performed. An accident such as breaking (not shown) or cutting off the electric wiring W does not occur.

The pattern is shifted from the concentric pattern.

Looking up at the conventional ceiling embedded lamp, the user is familiar with a plurality of concentric patterns in which the lower frame and the like of the inner cylinder 4 are constituted by the lower frame of the frame 2 and the outer cylinder 3 and the like. Since the viewer recognizes this as a change in the balance, the ceiling embedded lamp 1 is excellent in aesthetic appearance. Further, since the center c4 of the inner cylinder 4 is provided farther from the center c3 of the outer cylinder 3 to the position of the projection p3 provided at a predetermined position on the inner peripheral side surface of the outer cylinder 3, The opening 4a of the inner cylinder 4 is
When turning in the direction, the inner cylinder 4 hardly collides with the outer cylinder 3.

Thus, even when the illumination direction is directed to the direction of the projection p3, the inner cylinder 4 can be swung largely. In addition, since the outer cylinder 3 is cut off, the heat from the inner cylinder 4 can be smoothly radiated. Therefore, even if the illumination lamp L is turned on, the temperature of the ceiling recessed lamp 1 increases. Difficult to do.

In order to prevent the inner cylinder from hitting the outer cylinder, the inner cylinder is cut out so that the inner cylinder can be swung around the cantilevered structure inside the outer cylinder. The inner cylinder does not collide with the outer cylinder.

Thus, the inner cylinder can be swung large. In addition, since the outer cylindrical body has a cut-out shape, heat can be smoothly radiated from the inner cylindrical body. Therefore, even when the illumination lamp is turned on, the ceiling hardly rises in temperature.

If the outer cylinder is rotated 360 degrees in a certain direction, the next rotation of the outer cylinder will be 360 degrees in a direction opposite to the certain direction. In addition, by rotating the electric wiring many times in the same direction, an accident such as breaking a joint between the electric wiring and the socket or cutting off the electric wiring does not occur.

In the ceiling-mounted lamp according to the seventh aspect, since the heat sink is provided at the top of the inner cylinder, the outer cylinder is less likely to be heated. The ceiling-mounted lamp according to claim 8 has a simple structure in which the inner cylinder is provided in a cantilever structure on the inner peripheral side surface of the outer cylinder so as to be rotatable in the vertical direction. As a result, the number of parts can be reduced, so that the manufacturing cost can be reduced and the assembling process can be simplified.

When the illumination direction is changed, the side of the lower end of the inner cylinder facing the portion where the cantilever structure is provided can be easily pulled out from the outer cylinder. In addition, in this ceiling-mounted lamp, the outer cylinder is provided rotatably with respect to the frame, so that the inner cylinder can be easily held by holding the lower end of the inner cylinder with a finger or the like pulled out from the outer cylinder. Can be rotated. As a result, the illumination direction can be easily changed.

Further, in this ceiling-mounted lamp, since the shape of the inner cylinder is sharply narrowed down toward the zenith, the inner cylinder is provided with a cantilever structure in the outer cylinder.
