Abstract

PURPOSE: To prevent the cutoff of light and use a material excellent in light resistance and strength for a pedestal by providing linear support members supporting a fluorescent lamp to pinch it and the pedestal inserted with the linear support members. CONSTITUTION: A lamp holder is constituted of a pedestal 1 and linear support members 4. The pedestal 1 is constituted of a fitting section 1a for fitting the pedestal 1 to a luminaire cover and an insertion section 1b for inserting the linear support members 4. U-shaped grooves 3 are provided on the back face and side face of the fluorescent lamp arrangement side face of the pedestal 1. The U-shaped portions of the linear support members 4 are inserted into the grooves 3. When the linear support members 4 are to be inserted into the pedestal 1, the linear support members 4 are inserted from the back face sections of the grooves 3 of the pedestal 1. Since a fluorescent lamp is supported by the linear support members 4, the cutoff of light does not occur, and a material excellent in light resistance control and strength can be used for the pedestal 1.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lamp holder for supporting a fluorescent lamp so as to sandwich it.

[0002]

2. Description of the Related Art Conventionally, as a lamp holder, FIG.
A lamp holder made of metal such as stainless steel as shown in FIG. 8A and a lamp holder made of transparent resin such as polycarbonate as shown in FIG. 8B have been used. The lamp holder is attached by screwing it at the opening at the bottom thereof.

[0003]

However, as shown in FIG.
The metal lamp holder (a) is resistant to heat and excellent in light resistance, but the lamp holder portion blocks the light emitted from the fluorescent lamp, so that the light is cut off. on the other hand,
Since the transparent resin lamp holder of FIG. 8B has a light-transmitting property, light is not cut off, but it is weak in light resistance and may be broken when a strong force is applied.

[0004]

The lamp holder of the present invention comprises a linear support member for supporting the fluorescent lamp so as to sandwich it, and a pedestal into which the linear support member is fitted.

[0005]

According to the lamp holder of the present invention, the fluorescent lamp is formed by separating the linear supporting member for supporting the fluorescent lamp so as to be sandwiched and the pedestal into which the linear supporting member is fitted, and constructing the lamp holder. It is possible to prevent the breakage of light by supporting it with a supporting member having a shape of a circle, and to make the pedestal from a material having excellent light resistance and strength.

If grooves are provided on the back surface and side surfaces of the pedestal with respect to the surface on the fluorescent lamp arrangement side, and the linear support members are fitted into the grooves, the linear support members can be pulled out toward the fluorescent lamp arrangement side. It is possible to support a stable fluorescent lamp.

If the thickness of the portion of the pedestal into which the linear support member is fitted is made thicker than the other portions, the pedestal can more stably support the linear support member.

Further, if the pedestal is formed into a disc shape partially cut into an arc shape, the pedestal is rotated and the end portion is bent inward in a "U" shape. The pedestal can be fitted to.

[0009]

Embodiments of the present invention will be described in detail below with reference to the drawings.

FIG. 1A is a perspective view showing a pedestal of an embodiment of the lamp holder of the present invention, and FIG. 1B is a perspective view showing a state of the lamp holder having a linear support member attached to the pedestal. Is. 2 and 3 are views showing a method of attaching the linear support member to the pedestal.

As shown in FIG. 1B, the lamp holder is composed of a pedestal 1 and a linear support member 4, and the pedestal 1 is shown in FIG.
As shown in (a), it comprises a mounting portion 1a for mounting the pedestal 1 to the lighting equipment cover, and a fitting portion 1b for fitting the linear support member 4 therein. A groove 3 is provided on the back surface and side surface of the pedestal 1 with respect to the surface on the side where the fluorescent lamp is arranged, and the groove 3 is provided in a "U" shape. Is fitted. The linear support member 4 is fitted into the pedestal 1 as shown in FIG.
This is performed by inserting the linear support member 4 from the back surface into the U-shaped groove 3 provided in the pedestal 1. FIG. 3 is a view showing a state in which the linear support member 4 is fitted in the pedestal. In addition, here, a part of the linear support member (fitting portion) is bent into a “U” shape (C in FIG. 2), and correspondingly, a “U” -shaped groove is provided on the pedestal. However, the shape of the fitting portion of the linear support member is not limited to the U-shape, but may be an arc shape, a triangular shape or the like as long as the linear support member can be stably fitted and fixed to the pedestal. The shape of the groove may be defined in accordance with the above.

To attach the lamp holder to the lighting fixture cover, as shown in FIG. 6, the linear support member 4 is attached to the lighting fixture cover 5 whose end portion is bent inward in a U shape. Place the lamp holder in the fitted state, and move the lamp holder in the X direction so that the A part (shown in FIG. 6) of the lamp holder is inserted and fitted into the bent portion in the U shape. The lamp holder of this embodiment is attached to the lighting equipment cover by rotating 90 degrees. The lamp holder can be rotated and attached because the disk-shaped attachment portion 1a of the pedestal 1 is cut into an arc shape, so that the lamp holder can be arranged in the lighting fixture cover 5, and the lamp holder can be attached in the X direction. When rotated, as shown in Figs. 6 and 7, the lamp holder A
This is because the convex portion of the portion is inserted and fitted and fixed to the portion B of the lighting equipment cover 5.

According to such a mounting method, the lamp holder can be fixed to the lighting fixture cover without a set screw, and the lamp holder can be easily attached to and detached from the lighting fixture cover.
Needless to say, it can be more firmly fixed by fixing it to the lighting equipment cover 5 through the opening 2 provided in the pedestal 1 with a set screw or the like.

As a material for the linear support member 4, a metal such as stainless steel can be used. As the material of the pedestal 1, a metal such as stainless steel or a synthetic resin such as ABS (alkylbenzene sulfonic acid) resin can be used.
Any material may be used as long as it can sufficiently support the linear support member that supports the fluorescent lamp.

FIG. 4 (a) is a view showing the pedestal 1 in a third corner projection method, and FIG. 4 (b) is a rear view thereof. The shape of the pedestal is not particularly limited to the shape shown in this embodiment, as long as the linear support member is attached and it can be attached to the lighting equipment cover. If the linear support member can be supported, the pedestal may have a flat plate shape as shown in FIG.

[0016]

As described above, according to the present invention,
Since the fluorescent lamp is supported by the linear support member, light is not cut off, and a material having excellent light resistance and strength can be used for the pedestal.

If a groove is provided on the back surface and side surface of the pedestal with respect to the surface on the fluorescent lamp arrangement side, and the linear support member is fitted into this groove, the linear support member can be pulled out toward the fluorescent lamp arrangement side. It is possible to support a stable fluorescent lamp.

Further, if the thickness of the portion of the pedestal into which the linear support member is fitted is made thicker than the other portions, the support of the linear support member by the pedestal becomes more stable.

In addition, if the pedestal is shaped like a disc with an arcuate part cut, the pedestal is rotated and the end of the pedestal is bent inward in a U-shape. Can be fitted to the part.
