The motor 61 is stopped at a fixed position where the sensor 69 detects the detection unit 67 of the sensor wheel 66.

Next, the operation of the present embodiment will be described.

First, the case where the straight tube lamp 1 is mounted on a lighting fixture will be described.

The center of the tube 2 of the straight tube lamp 1 is rotated by a rotating mechanism.
The tube holder 2 is attached to the lamp holding portion 55 of the 41 by engaging the vicinity of both ends of the tube 2 with the holder 71 of the lamp supporting portion 15 from above. When the center of the tube 2 of the straight tube type lamp 1 is engaged with the lamp holding portion 55 of the rotating mechanism 41, since the interval between the pair of rollers 43 and 44 is smaller than the diameter of the tube 2, the spring 54 is attached. While the lever body 51 swings outward against the force, the tube 2 is engaged between the pair of rollers 43 and 44 via the belt 45, and in the engaged state, the tube 2 comes from the lower surface of the tube 2 While being in contact with the belt 45 on both sides, a pair of rollers 43 and 44 are contacted via the belt 45 slightly above both sides of the tube 2, and the tube 2 of the straight tube type lamp 1 is held by the lamp holding portion 55 ( Pinched).

Therefore, the straight tube lamp 1 is rotated by the rotating mechanism 41.
Of the lamp holder 55 and the lamp holder 15 on both sides
It is securely held at three locations 71. At this time, the pair of pins 4 at each end of the straight tube lamp 1 are arranged vertically. If the position of the pin 4 is shifted by the initialization operation by turning on the power switch 23 of the operation unit 22, the correction is made.

Then, the straight tube lamp 1 having the support portion 12 is provided.
5A, the pins 4 at both ends of the straight tube lamp 1 are engaged with the slits 8 of the pin receiving portion 9 through the attachment / detachment grooves 7 of the socket 5 as shown in FIG.

In this state, the constant rotation switch 24 of the operation unit 22
Is operated once. As a result, the motor 61 rotates, and the driving force from this motor 61 is transmitted to the roller 42,
The belt 45 rotates together with the belt 42, and the straight tube lamp 1 rotates together with the belt 45.

The roller 42 rotates 90 ° and the sensor wheel
When the detection unit 67 of 66 is detected by the sensor 69, the motor 61 stops automatically.

At this time, if no slippage occurs between the belt 45 and the straight tube lamp 1, the straight tube lamp 1 is also moved to 9
It turns by 0 ° and stops in the fully mounted state. Therefore, as shown in FIG. 5 (b), the pin 4 of the straight tube type lamp 1 is rotated by 90 ° together with the pin receiving portion 9 of the socket 5 to be mechanically held, and at the same time, It is electrically connected to the terminal.

When a slippage occurs between the belt 45 and the straight tube lamp 1 and the straight tube lamp 1 does not rotate up to 90 °, the jogging switch 35 of the operation unit 22 is operated. As a result, the straight tube lamp 1 rotates by a small angle only while the inching switch 35 is operated, so that the straight tube lamp 1 is adjusted to a completely mounted state in which the lamp 1 rotates 90 °.

When the straight tube lamp 1 is securely mounted in the socket 5, the support portion 12 is pulled downward, and the straight tube lamp 1 is pulled from the lamp holder 55 of the rotating mechanism 41 and the lamp support portions 15 on both sides. Remove three places of the holder 71.

Next, a case where the straight tube type lamp 1 is removed will be described.

With the support 12, the lamp holder 55 of the rotating mechanism 41 and the holder 71 of the lamp support 15 on both sides are engaged with the straight tube lamp 1 mounted on the socket 5.

In this state, the constant rotation switch 24 of the operation unit 22
Is operated once, the motor 61 rotates as described above, and the driving force from the motor 61 is transmitted to the roller 42, and the belt 45 rotates together with the roller 42, and the belt 45 rotates directly together with the belt 45. The tube lamp 1 rotates. After the roller 42 rotates by 90 °, the motor 61 stops automatically.

At this time, if no slippage occurs between the belt 45 and the straight tube lamp 1, the straight tube lamp 1 is also moved to 9
It rotates by 0 ° and stops in a completely detachable state.

When a slippage occurs between the belt 45 and the straight tube lamp 1 and the straight tube lamp 1 does not rotate up to 90 °, the jogging switch 25 of the operation unit 22 is operated. As a result, the straight tube lamp 1 rotates by a small angle only while the inching switch 25 is operated, so that the straight tube lamp 1 is adjusted to a completely detachable state in which the straight tube lamp 1 rotates 90 °.

When the straight tube lamp 1 becomes detachable from the socket 5, the support 12 is moved downward, and the straight tube lamp 1 is removed from the socket 5.

As described above, the straight tube type lamp 1 is
The straight tube type lamp 1 can be attached to and detached from the lighting fixture through the rod-shaped support portion 12 while being held by the rotating mechanism 41.
By operating the operation unit 22 of the support unit 12, the straight tube lamp 1 can be rotated by the rotation mechanism 41 by the driving of the motor 61 of the operation unit 14 and can be attached to and detached from the lighting fixture. Even if it is installed at a high place, the work of attaching and detaching the straight tube lamp 1 can be easily performed.

Also, with a single operation of the constant rotation switch 24 of the operation unit 22, the straight tube lamp 1 can be rotated by an angle required for mounting and dismounting the straight tube lamp 1. 1 can improve the workability of attachment and detachment.

Further, since the straight tube lamp 1 can be turned while the inching switch 25 of the operation section 22 is operated, the turning amount of the straight tube lamp 1 can be finely adjusted.

Further, the cover 16 arranged along the lower side of the straight tube lamp 1 held by the operation section 14 can protect the straight tube lamp 1 at the time of attaching and detaching work. Further, it is possible to prevent falling objects such as dust from being scattered by receiving the objects during the attaching / detaching operation.

Further, since the battery 26, which is the power supply of the motor 61, is removably disposed on the support portion 12, it can be used in a portable manner and the battery can be easily replaced.

Although the rotating mechanism 41 uses the belt 45 as a rotating body, the rotating mechanism 41 may be configured so that the straight tube-type lamp 1 is rotated by a plurality of (for example, three) rollers. .

The motor of the operating section 14 is not limited to the motor 61, but may be a solenoid or the like.

A commercial power supply may be used as the power supply.
