Description

  The present invention relates to a lighting fixture in which a rotating part is rotatably provided at an upper part of a frame base, an arm is attached to the frame base or a press plate, and a terminal block is provided at the tip of the arm.

In a conventional embedded lighting fixture, a rotating part is provided at the upper part of a frame base so as to be rotatable in a horizontal direction by a presser plate, and a lamp is provided at the rotating part. Therefore, the lamp is supported so as to be rotatable in the horizontal direction via the rotating portion.
In this luminaire, an arm made of a leaf spring is extended in the lateral direction from the frame base, and a terminal block is provided at the tip of the arm.

When installing the lighting fixture on the ceiling, first, the horizontal (horizontal) arm is elastically deformed to stand up vertically.
Next, a lighting fixture is inserted into the mounting opening of the ceiling, and then the arm is returned to the horizontal (horizontal) position by a spring force. After returning the arm to the side, connect the external wire connected to the terminal block to another device.

  However, since the arm is formed of a leaf spring, if the external electric wire connected to the terminal block is pulled when connecting to another device, the arm elastically deforms and the external electric wire approaches the high temperature part of the lamp. There were also problems such as obstructing the rotation of the lamp with an elastically deformed arm.

As a lighting fixture that solves this problem, a lighting device in which an arm is formed of a steel plate is known.
By forming the arm with a steel plate, it is possible to prevent the arm from being elastically deformed by being pulled by the external electric wire when the external electric wire connected to the terminal block is connected to another instrument.
Therefore, it can prevent that an external electric wire adjoins to the high temperature part of a lamp, or obstructs rotation of a lamp with the arm which carried out elastic deformation.

Here, since the lighting fixture has the arm formed of a steel plate, when the lighting fixture is attached to the ceiling, the lighting fixture is first inclined and the arm is inserted into the mounting opening of the ceiling.
Next, it is necessary to return the lighting fixture to a vertical position and insert the frame into the ceiling mounting opening (see, for example, Patent Document 1).

The arm is mounted so that it can stand up, and a terminal block is provided at the tip of the arm, and the rotating part is provided with a recess in which the arm is accommodated when the arm is raised, and the arm is stood up and stored in the recess during construction. After the construction, the arm falls horizontally and falls out of the recess, and in this state, the rotating portion is rotated to shift the position of the recess, thereby preventing the arm from standing up. It is characterized by that.

The arm is attached to the frame base or presser plate via a support shaft so that the arm can stand up, and a terminal block is provided at the tip of the arm. In addition, the rotating part is provided with a recess in which the standing arm is accommodated.
Then, during the construction, the arm was erected and stored in the recess, and after the construction, the arm fell down horizontally due to its own weight and pulled out of the recess.
Further, the rotating part is rotated to shift the position of the recessed part while the arm is pulled out from the recessed part, so that the arm is prevented from standing up.

Therefore, at the time of construction, the frame base and the arm can be constructed in an integrated state by raising the sideways (horizontal) arm and storing it in the recess.
Thereby, the construction which attaches a lighting fixture can be performed easily.

Further, by rotating the rotating portion and shifting the position of the concave portion, the horizontal (horizontal) arm is prevented from standing up.
Therefore, when connecting the external electric wire connected to the terminal block to another instrument, it is possible to prevent the arm from being pulled up and standing by the external electric wire.
Thereby, it is possible to hold the terminal block in a predetermined position after the completion of the construction and prevent the external electric wire from approaching the high temperature part of the lamp or hindering the rotation of the lamp by the standing arm.

  Further, the present invention is characterized in that a mark for confirming the position of the concave portion is provided.
