Description

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

Conventional lighting equipment such as this type of jump rear has a structure in which the lamp is attached to the tip of the arm, but in the past, lighting parts such as a ballast, lamp holder A, and shade were attached to the chassis of the lamp. Since the chassis is attached to the arm, the chassis becomes large, and the chassis must be made of thick material that can withstand the weight of the ballast, increasing the weight of the entire lamp. This method has the disadvantage that installation workability is poor because the tool must be deformed and inserted inward through the opening of the shield to securely attach the shield.

The present invention takes into account the above points, and by attaching a heavy ballast to the arm, a thin material can be used for the chassis, which improves the handling of the lamp and provides a lighting apparatus that can be obtained at low cost. The purpose is to provide

In addition, the present invention uses a thinner material for the chassis and can be made smaller than the case where the lamp holder is attached to the shade of the lamp, making it easier to install the lamp, improving the workability of installing the lamp, and making it cheaper. The purpose of this invention is to provide a lighting device that is easy to package.

The structure of the present invention consists of an IIA main body, an arm attached to the main body, and a lamp attached to the tip of the arm and containing a lamp, and the lamp includes a shade and a ballast for lighting the lamp. It has a lighting component, a chassis, and a lamp holder that meet the ballast, and the ballast is directly attached to the arc.

Furthermore, in the present invention, the ballast is directly attached to the arm, the chassis is attached to the 7-5, and the lamp holder is attached to the shade.

Next is the main event! The configuration of one embodiment of the present invention will be explained with reference to the drawings.

(1) is the main body of the device, which is designed to be suspended from a ceiling or the like. Inside this body (1) is a pull switch (2
) is provided, and the operation of this pull switch (2) It (
3) is placed at 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, (5) is a lamp that is attached to the tip of each of the above 7-^ (4), which includes a chassis (6), a shade (7), a lamp holder (8), a ballast (9), and a lighting tube socket). II, and a lighting section such as a night light socket aυ.

The chassis (6) has a mounting piece part @ for the lighting tube socket (a) and a mounting piece part (a3) for the night light socket (am) integrally protruding from the central part of both sides.

Also, locking pieces a4 are formed at both ends of both side edges of the chassis (6) and are bent upward.

Further, in the center of the chassis (6), an arm abutting portion a is curved in an arc shape.

Further, a shade mounting leg bracket is attached to the lower surface of the chassis (6).

The shade (7) is composed of an upper shade member aη and a lower shade member shaft, and an opening 11 into which the chassis (6) is fitted is formed in the center of the upper shade member &η. The inner diameter is formed to be slightly larger than the outer machine of the chassis (6), and the hook whose upper surface is inclined downward in correspondence with the locking piece 4 of the chassis (6) is a protrusion (2).
is formed, and the dimension between this pull #S protrusion and the chassis (
6) is larger than the dimension between the locking pieces a4.

Also, on the upper surface of this upper surface shade member a, the arm (4
) is formed.

Furthermore, in the center of the lower surface of the lower shade member, there is a mounting screw (2) screwed into the screw hole (2) of the shade mounting leg (2).
An insertion hole is formed.

A lamp holder attachment projection (2) is provided at the center of the shade member aη, and the upper end of a lamp holder (8) formed of an elastic piece is fixed to this projection.

Further, a power supply wire (2) is inserted through the arm (4).

Also on the surface is a lamp socket connected to an annular fluorescent lamp (2).

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

Attach the chassis (6) to the tip of each arm (4) and the lower 1[K stabilizer (9)] of this chassis (6). Fit it into (6), and the catch is Tsuki II! When pushed against the elasticity of AaI, the hook projection (2) is locked by the locking piece a4, and the upper shade member fin is held by the arm (4)K. In this state, the tip of the arm (4) is engaged with the concave portion C1jK.

Then, hold the lamp holder (8) K lamp (to) attached to the shade member an K IIIE, and connect the lamp aIK lamp socket (goods).

Next, combine the lower shade member (■) with the upper part (FII*tlη), and screw the mounting screw (2) inserted into the insertion hole into the screw hole (■) of the shade mounting leg assembly (F). 7) Assemble.

Note that if the arm (4) is made of a material with good thermal conductivity such as a metal pipe, the heat dissipation effect of the ballast (9) can be further enhanced, and there is no need to adopt a structure for heat dissipation in the chassis (6). The chassis (6) can be made thinner.

Also, since the opening of the shade member aη is formed in a size that allows the chassis (6) to be fitted into it, the shade member aη of the first shade member a? ), there is no need to tilt the #4 protrusion (up to)
Fit the chassis (6) against the elasticity of the locking piece a4
Attach it with a lock.

According to this INK, since the ballast of the light fixture attached to the arm is attached to the 7-5, there is no need to consider the weight of the ballast for the chassis (the chassis can be made thinner, and the chassis can be made smaller
First, the spear is easy to handle.

Obtained cheaply.

In addition, since the present invention is equipped with a SeFK lamp holder,
Attaching the shade sometimes does not require deforming the lamp holder, making it easy to attach the shade, making the chassis thinner and smaller, and making it possible to make the chassis smaller when packaging.
＜、Set V can be placed between each arm and packaged in a small size.
Obtained at 11.
