Description

[Detailed description of the invention] This invention relates to a lighting equipment that has a lighting equipment body and a plurality of lighting bodies radially outward from the lighting equipment body, especially a jump rear, and particularly relates to a mechanism between the lighting equipment body and the lighting equipment. This relates to improvements in physical and electrical connection mechanisms.

Conventionally, in multi-light lighting fixtures in which an arm with a lamp body at one end is attached to the fixture body in a radial manner, the fixture body and the arm are often attached with screws or the like, and the electrical connection between the two is difficult. For example, the lead wire on the lamp body side was passed through the arm part and crimped inside the device body, or the lead wire led out from the main body was connected to the socket of the lamp body by soldering or screwing.

With such a structure, the device body and the lamp body cannot be easily separated and packaged separately, resulting in a large package size.
Packaging costs, transportation costs, and storage management costs increased, and assembly work was troublesome, and disassembly for repair was also complicated.

Therefore, a downward protrusion and a groove are formed on the end of the arm, and a hole is provided inward from the periphery of the instrument body through the separation part, so that the protrusion is inserted into the hole and the groove is inserted into the separation part. A mechanical connection is made in which the side wall of the arm is brought into close contact with the circumferential surface of the instrument body, and an electrical connection is provided at the tip of the protrusion and in the hole, for example, as disclosed in Japanese Utility Model Publication No. 52-
It can be seen in Publication No. 50603.

However, in such a configuration, in order to cope with the downward load of the lamp, the side wall of the arm must be in contact with the peripheral surface of the fixture body over a certain length and area in the vertical direction. The shape of the arm was limited, limiting the degree of freedom in design, and there was a significant lack of stability when upward force was applied to the lamp body.

Further, since the electrical connection body on the lamp body side is fixed to the lamp body, it is difficult to clean the lamp body by washing with water or the like.

This idea was created in view of the above drawbacks, and improved the attachment part between the arm with the lamp body and the main body of the lighting fixture in order to solve the above problems such as reducing the size of the packaging. The present invention provides a lighting fixture with improved stability against downward loads and upward forces.

An embodiment of this invention will be described below with reference to FIGS. 1 to 5.

In the figure, 1 is a main body case equipped with electrical parts such as a switch in the center of the lower surface, 2 is a first arm part that protrudes radially from the main body case 1 at regular intervals and has a U-shaped cross section with an open bottom surface, and 3 is a A locking screw hole provided on the upper surface of the first arm part, 4 is a first electrical connection body attached to the tip 2a of the first arm part 2, and one end is a switch etc. provided in the main body case 1. connected to electrical components.

5 is a stabilizer storage case fixed to the upper surface of the main body case 1; 6 is a main body cover integrally molded to cover the lower side of the main body case 1 and attached to the main body case 1; 7 is a first main body cover; This is a main body cover arm portion that closes the lower side of the arm portion 2, and is molded integrally with the main body cover 6.

The inner walls 7a and 7b of the main body cover arm section 7 are attached to the first arm section 2 so as to maintain gaps 8a and 8b.

Numeral 9 is a lamp body equipped with a light source such as a fluorescent lamp inside, 10 is a part of the lamp body 9, one end of which fits inside the lamp body, and is fixed to the lamp body 9 with a screw or the like, and a second end is attached to the other end. 1 Inner wall of arm part 2 and main body cover arm part 7? a, 7b, a second arm 1 having a rectangular cylindrical insertion portion 10a circumscribing the first arm portion 2, which is inserted laterally into the gaps 8a, 8b between the second arm 1;
0b is a protrusion provided on the upper surface of the lamp body 9 side of the insertion portion 10a so as to protrude downward; when attached to the first arm portion 2, the first
The electrical connection body 4 is brought into contact with the tip 2a of the first arm portion 2 so as to be restricted to a certain position inside the lamp body 9.

10c is a through hole provided in the second arm 10 corresponding to the screw hole 3 of the first arm 2 when the protruding portion 10b comes into contact with the tip 2a of the first arm 2; 11 is a through hole provided in the second arm 10; a protruding engagement portion 11a molded from an elastic resin or the like and fitting into the locking portion 4a of the first electrical connection body 4; and the protrusion 11a;
A second electrical connector 12 is a lead wire led out from the second electrical connector, the other end of which is connected to a light source.

Reference numeral 13 designates a wire clip molded from an elastic resin that detachably holds the lead wire 12 and locks into the hole 10d of the second arm inside the lamp body.

Assembling the multi-lamp lighting fixture with such a configuration is performed by opening one end from the lateral direction so as to surround the first arm portion 2 of the main body of the main body case 1 to which the ballast storage case 5, the main body cover 6, and the main body cover arm portion 7 are fixed. The insertion part of the second arm 10 equipped with the lamp body 9 is inserted into the hole 10c of the second arm 10, and the screw hole 3 of the first arm part 2 is secured with a thumbscrew to make the first electrical connection. body 4 and second electrical connection body 11
All you have to do is connect it.

In addition, when removing the lamp body 9, the above procedure may be performed in reverse.

In this way, this multi-light lighting fixture can be attached and detached without using tools, and the second arm 10 circumscribes the second arm part 2 and is supported by the cover arm, so that As shown, the upper part of the tip of the first arm part 2 and the lower part of the tip of the second arm part 10 can support the load of the lamp body 9, and the load of the lamp body 9 can be supported by the upper part of the tip of the first arm part 2 and the lower part of the tip of the second arm part 10. Since the receiver supports the force at the lower end of the arm portion 2 and the upper end of the second arm 10, it can sufficiently withstand these loads.

Note that the lower side of the bag-shaped insertion part does not need to be connected, and the locking part does not need to be a screw.

As mentioned above, this idea consists of a main body case equipped with electrical parts such as switches in the center of the lower surface, and a cross-sectional component that protrudes radially from the main case at approximately intervals, is integrally formed with the main case, and has an open bottom surface. The main body cover is attached to the main body case so as to close the lower side of the main body case, and is formed integrally with the main body cover, leaving a gap on the outside of the first arm portion. a main body cover arm portion that is positioned and closes the lower side of the first arm portion;
A first electrical connection body is attached to the tip of the arm part and electrically connected to the above-mentioned electrical components provided in the main body case, a lamp body is fixed to one end, and the first arm part is attached to the other end. A second arm has a rectangular tube-shaped insertion portion circumscribing the second arm, and is disposed inside the lamp body facing the rectangular tube-shaped insertion portion of the second arm, and is connected to a light source provided inside the lamp body. a second electrical connection body that is electrically connected to the first electrical connection body when the insertion part is inserted into the first arm part; Since it is a multi-light lighting fixture characterized by being removably inserted into the first arm part,
To obtain a multi-lamp lighting fixture in which the fixture body and the lamp body can be easily attached and detached, and can sufficiently withstand the downward force and upward force caused by the load of the lamp body.
