Description

DETAILED DESCRIPTION OF THE INVENTION Field of the Invention The present invention relates to a decorative lighting device in which a decorative cylinder is rotated by a motor.

Conventional structure and problems When rotating a decorative tube using a motor in a conventional decorative lighting device, maintenance and inspection is difficult because one end of the decorative tube is simply connected to the rotating shaft of the motor. If a large force is applied to the decorative tube during this process, there is a risk of damaging the motor's rotating shaft.

OBJECTS OF THE INVENTION Accordingly, an object of the present invention is to provide a decorative lighting device that is extremely unlikely to damage the rotating shaft of the motor.

Structure of the Invention To achieve this object, the present invention includes a chassis, a motor attached to the chassis, a transparent decorative tube with one end attached to the rotating shaft of the motor, and a decorative tube attached to the chassis. a socket located in the hole at the other end of the tube;
This constitutes a decorative lighting device characterized by comprising a lamp attached to the socket.

Description of examples Next, embodiments of the present invention will be described with reference to the drawings.

The decorative lighting device according to this embodiment, the appearance of which is shown in FIG. 1, is suitable for mounting on a wall, and has a cover 1 made of, for example, milky white synthetic resin, with a notch 2 formed at the rear edge of the upper and lower center of the cover 1. It is. This decorative lighting device is powered by a cord 4 which includes an intermediate switch 3. 6 is a plug. FIG. 2 is a cross-sectional view taken along the line 1 in FIG.

The decorative tube 9 has a cylindrical transparent tube 91L and end caps 9b and 90 fitted to both ends thereof. Translucent tube 91
For example, the inner surface of L is made of transparent synthetic resin and is screen printed in black except for the star-shaped transparent part 9d, and the transparent part 9dK is screen printed with translucent colors such as red, blue, green, etc. It is alms. The end caps sb and 9c are made of aluminum, for example. One end of the decorative tube 9, that is, the end cap 9C is connected to the rotating shaft 8 of the motor 8 via the joint 10.
attached to a. Socket 11 is attached to chassis 6 with mounting piece 1
2, and is located at the other end of the decorative tube 9, that is, within the hole 13 of the end cap 9b. and,
Lamp 14 is attached to socket 11. Both sides of the cover 1 are each attached to mounting pieces 7.12 by means of thumbscrews 16. When the motor 8 is powered on, the decorative tube 9 rotates relatively gently as the rotating shaft 8a rotates. The top of the lamp 14 is colored through the star-shaped transparent portion 9d, and is projected onto the cover 1 as an enlarged star-shaped pattern, which moves slowly. A star-shaped pattern is directly projected onto the wall surface from the notch 2 of the cover 1, and the pattern also moves slowly (see the dotted line in FIG. 1).

To replace the lamp 14, remove the thumb screw 16, remove the cover 1, remove the nut 16, and then the mounting piece 12 can be removed with the socket 11 and lamp 14 still attached, making it convenient to replace the lamp 14. It is. Generally, during maintenance and inspection, even if force is inadvertently applied to the decorative tube 9, the inner edge of the hole 13 and the socket 11 will come into contact and the displacement of the decorative tube 9 will be kept to a minimum. By preventing force from being applied, damage to the rotating shaft 8a can be prevented. A speed reduction mechanism is built into the motor 8 to allow the decorative tube 9 to rotate slowly, but since this speed reduction mechanism is usually composed of synthetic resin gears, it is structurally weak, and the other end of the decorative tube 9 has a socket. 11 is very useful.

Effects of the Invention As is clear from the above description, the decorative lighting device of the present invention has one end attached to the rotating shaft of the motor and the other end of the decorative tube having its displacement regulated by the socket.
Even if force is inadvertently applied to the decorative tube during maintenance and inspection, there is extremely little risk of damage to the rotating shaft of the motor, which is advantageous in handling.
