Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a lighting device, such as a chandelier, in which a lighting device is attached to the tip of an arm.

Conventional lighting equipment such as this type of chandelier has a structure in which the lamp is attached to the end of the arm, but in the past, lighting parts such as a ballast, lamp holder, and shade were attached to the chassis of the lamp, and this chassis was attached to the arm. In order to attach the ballast to the ballast, the chassis becomes large, and the chassis must be made of a material thick enough to withstand the weight of the ballast, increasing the weight of the entire lamp and causing deformation of the lamp holder attached to the chassis. The shade has to be installed by inserting it inward through the opening of the shade, which has the disadvantage of poor installation workability.

The present invention has been made in view of the above points, and it is possible to use a thin material for the chassis by attaching the mounting surface of the heavy stabilizer to the outer surface of the arm on the axis of the arm, facing the arm, and through the chassis. The object of the present invention is to provide a lighting fixture that can be easily handled, and can be obtained at low cost.

Furthermore, by attaching the shade of the lamp holder to the lamp holder, the chassis can be made of a thin material and can be made compact, the lamp can be easily installed, the lamp installation workability is good, it can be obtained at low cost, and it is easy to package. The purpose is to provide good lighting equipment.

The structure of the present invention consists of a device body, an arm attached to the device body, and a lamp attached to the tip of the arm and containing a lamp, and the lamp is a lighting component including a shade and a ballast for lighting the lamp. a chassis and a lamp holder, the mounting surface of the ballast is placed on the outer surface of the arm on the axis line facing the arm, the ballast is attached via the chassis, and the chassis is attached to the arm. It is something.

Further, in the present invention, the mounting surface of the ballast is mounted on the outer surface on the axis of the arm so as to face the arm, the chassis is mounted on the arm, and the lamp holder is mounted on the shade.

Next, the configuration of an embodiment of the present invention will be explained with reference to the drawings.

1 is the main body of the device, which is suspended and supported from a ceiling or the like. A pull switch 2 is provided inside this main body 1, and an operating string 3 of this pull switch 2 is provided.
is suspended from the bottom of the main body 1.

Further, the base ends of a plurality of arms 4 molded from metal pipes or synthetic resin are fixed to the outer periphery of the main body 1, and each arm 4 projects radially.

Next, reference numeral 5 denotes a lamp attached to the tip of each arm 4, including a chassis 6, a shade 7, and a lamp holder 8.
It is also comprised of lighting parts such as a ballast 9, a lighting tube socket 10, and a night light socket 11.

The chassis 6 has a mounting piece 12 for the lighting tube socket 10 and a mounting piece 13 for the night light socket 11 integrally protruding from the center on both sides.

Further, locking pieces 14 are formed on both ends of both side edges of the chassis 6 and are bent upward.

An arm abutting part 15 is curved in an arc shape in the center of the chassis 6, and the mounting surface of the stabilizer 9 is aligned with the outer surface on the axis of the arm 4 on the lower surface. It is attached opposite to 4.

Furthermore, shade mounting legs 16 are provided on the underside of the chassis 6.
is attached.

The shade 7 is composed of an upper shade member 17 and a lower shade member 18, and an opening 19 into which the chassis 6 is fitted is formed in the center of the upper shade member 17. A hooking protrusion 20 is formed which is slightly larger than the outer diameter of the chassis 6 and whose upper surface is inclined downward in correspondence with the locking piece 14 of the chassis 6. Locking piece 14
It is formed larger than the size in between.

Further, a recessed portion 21 is formed on the upper surface of this upper surface shade member 17 to engage the arm 4 .

Furthermore, an insertion hole 24 for a mounting screw 23 to be screwed into the threaded hole 22 of the shade mounting leg 16 is formed in the center of the lower surface of the lower shade member 18 .

Further, a lamp holder attachment projection 25 is projected from the inner surface of the upper surface shade member 17, and the upper end of the lamp holder 8 formed of an elastic piece is fixed to this projection 25.

Further, a power supply wire 26 is inserted through the arm 4.

Further, 27 is a lamp socket connected to an annular fluorescent lamp 28.

Next, a method of assembling this embodiment will be explained.

A chassis 6 is attached to the tip of each arm 4, and a stabilizer 9 is attached to the lower surface of the chassis 6 with screws 29. Next, when the opening 19 of the upper shade member 17 is fitted into the chassis 6 and pushed in against the elasticity of the hooking protrusion 20, the hooking protrusion 20 is engaged with the locking piece 14, and the shade member 17 is attached to the arm. 4. In this state, the tip of the arm 4 is engaged with the recess 21.

Then, the lamp 28 is held in the lamp holder 8 attached to the upper shade member 17, and the lamp 28 is held.
Connect the lamp socket 27 to 8.

Next, the lower surface shade member 18 is attached to the upper surface shade member 1.
7 and inserted into the insertion hole 24
are screwed into the screw holes 22 of the shade mounting legs 16 to assemble the shade 7.

Note that the heat dissipation effect of the ballast 9 can be enhanced by using a material with good thermal conductivity, such as a metal pipe, for the arm 4.

The chassis 6 is fixed to the tip of the arm 4 having high rigidity and to the lower surface of the outer periphery of the arm 4 so as to face this arm, and on the back side, along the outer surface on the axis of the arm 4, there is a mounting surface for a heavy stabilizer. Therefore, the load on the stabilizer 9, which replaces the chassis 6, can be reduced, and the chassis 6 can be made thinner.

Further, since the opening 19 of the upper surface shade member 17 is formed in a size that allows the chassis 6 to fit therein, there is no need to tilt the upper surface shade member 17, and the chassis 6 can be fitted against the elasticity of the hook projection 20. The locking piece portion 14 can be locked.

According to the present invention, since the mounting surface of the ballast of the lamp attached to the arm is opposed to the outer surface on the axis of the arm and is attached via the chassis, the chassis can be reinforced, and the chassis can reduce the weight of the ballast. There is no need to consider this, and the chassis can be made thinner.

Further, in the present invention, since the lamp holder is attached to the shade, there is no need to deform the lamp holder when attaching the shade, and the shade can be easily attached.
The chassis can be made thin and compact, and when it is packaged, the chassis is small and a shade is disposed between each arm so that it can be packaged compactly and can be obtained at low cost.
