Description

[Detailed description of the invention]

[0001]

The present invention relates to a support position in which each of a plurality of support members that enter the lower surface of the reflector through a through hole formed in the reflector is located in the lower surface of the reflector.
A biasing member is provided movably along a movement path extending from a lower surface side of the reflection plate to a support release position, and a biasing member for moving and biasing each of the support members toward the support position is provided. In a series of pressing operations of pressing the support member moving to the support position side upward on the back side of the reflection plate, the support member moves to the support release position against an urging force, and The present invention relates to a lighting fixture in which the support member moves to the support position as the movement path of the support member enters the through hole, and the reflector plate is supported on the fixture body side.

[0002]

2. Description of the Related Art In a lighting apparatus, the reflector is moved toward the fixture body by a series of pressing operations in which the support member is pressed upward on the back side of the reflector without previously operating the support member of the reflector. Although it can be easily mounted, in a conventional lighting fixture, a support member for supporting the reflector is provided integrally with the tip of a leaf spring fixed to the fixture body side, and the support member is moved to the support position side by the elastic force of the leaf spring. The reflecting plate is placed and supported by the support member, and the peripheral edge of the through hole of the reflecting plate is pressed by the biasing force of the leaf spring, thereby moving the reflecting plate both vertically and horizontally. Are supported on the instrument body side in a state where each support member individually regulates (for example, actual 3-
No. 10567).

[0003]

For this reason, due to the distortion of the fixing member for fixing the leaf spring, the shape error of the leaf spring, and the like,
If the leaf spring is fixed in a posture different from the predetermined posture with respect to the instrument body, the relative position of the support position of the support member with respect to the instrument body side is deviated, and each support member moves in the vertical direction of the reflection plate. When the reflector is supported at its supporting position in a state where the movement in both the horizontal direction and the horizontal direction is individually regulated, the reflector may be distorted such as twisting or bending depending on the degree of deviation. There is. The present invention has been made in view of the above circumstances, and by devising the support structure of the support member, even if the relative position of the support position of the support member with respect to the appliance body side is deviated, the reflection plate is distorted. It is an object of the present invention to be able to support the reflection plate on the instrument body side in a state where the occurrence of the reflection hardly occurs.

[0004]

A feature of the present invention to achieve the above object is a lighting apparatus according to the first aspect, wherein the reflector is placed and supported so as to be movable in a horizontal direction with respect to the support member. The present invention is characterized in that a restricting portion for restricting the horizontal movement of the reflection plate by contact with the reflection plate placed and supported on the support member is provided separately from the support member.

[0005]

The reflecting plate is mounted and supported on the supporting member so as to be movable in the horizontal direction, and the restricting portion provided separately from the supporting member regulates the horizontal movement of the reflecting plate. Even if the support position deviates from the relative position with respect to the instrument main body, each support member supports the reflector in a state of being shifted from the support member by an amount corresponding to the deviation.

[0006]

Therefore, the position of the reflector in the horizontal direction is not restricted by the support member, and even if the support position of the support member is misaligned with respect to the appliance body, the reflector is less likely to be distorted. In this state, the reflector can be supported on the instrument body side.
