Description

  The present invention relates to a lighting fixture installed indoors.

  2. Description of the Related Art Conventionally, there is a lighting fixture that obtains a desired light flux by arranging and connecting LED modules each having a plurality of LED elements mounted on a substrate in a line.

  In the connection method of these LED modules, a connector for supplying power to the LED element is mounted on the LED module, and the connectors of the LED modules adjacent to each other are connected by a lead wire with a relay connector, etc. There is something to do.

For example, some relay connectors that connect LED modules include a main body portion that has a substantially rectangular parallelepiped shape and pin portions that protrude from opposing surfaces of the main body portion.
In this relay connector, the pin portion is connected to the input connector provided in the two LED modules to be coupled, and the main body portion is interposed between the two LED modules and is engaged with the concave portion provided in the LED module, The connection position of the LED module is controlled (for example, Patent Document 1).

  In addition, in an LED module in which a notch is formed on the substrate, the LED module is connected by a relay connector, and the lead wire of the relay connector is hooked on the notch, and the lead wire shields light emitted from the LED module. Some are controlled so as not to be performed (for example, Patent Document 2).

Further, in an LED module on which a plurality of LED elements are mounted, there is an LED module in which LEDs are arranged in a straight line, and input connectors and output connectors are mounted at positions shifted from the LED arrangement.
In this LED module, the input / output connector is mounted at a position deviated from the LED arrangement, so that when the LED module is connected, the connector does not block the light emitted from the LED, and the light continuity is achieved. (For example, patent document 3).

JP 2013-229276 A JP 2012-64390 A JP 2013-251444 A

However, although the relay connector of patent document 1 controls the connection position of the LED module connected, the method of fixing the connected LED module to a lighting fixture is not described.
There are LED module mounting methods that are fixed with screws, but it is necessary to provide an insulation distance between the LED element, wiring pattern, and fixing holes when fixing holes for screwing are provided on the board. The substrate becomes larger.

Further, the LED module of Patent Document 2 is provided with a notch in the substrate, and the lead wire of the relay connector is hooked when the LED module is connected.
However, this is because the lead wire is hooked after the LED module is attached to a mounting member such as a lighting fixture. To hook the lead wire in a state where the LED module and the mounting member are in contact with each other, the board or the lead wire is attached. There is a possibility of deformation and damage.
Further, it is considered that the mounting member needs to be processed such as a notch so that the lead wire is not pressed between the LED module and the mounting member.

Moreover, the LED module of patent document 3 makes the LED module and LED module adjoin without using a relay connector, and connects and connects the connector mounted in the LED module.
However, the LED module is manufactured in a certain size, and it is not possible to easily change the size of the LED module, such as expanding or reducing the size.
Therefore, depending on the lighting fixture to which the LED module is attached, it is necessary to provide a gap between the LED module and connect with a relay connector having a lead wire whose length can be adjusted. I can't keep it.

  Accordingly, the present invention has been made to solve the above-described problems, and an object thereof is to provide a coupling device that holds an LED module and maintains the continuity of light of the LED module.

  The coupling device according to the present invention is a coupling device that couples a light source module that is mounted on a mounted portion and linearly mounts a plurality of light emitting elements on a substrate, and has a facing side that faces the side of the substrate. A connecting and fixing portion attached to the attached portion; a connecting portion provided on the connecting and fixing portion; protruding from the opposite side toward the light source module; and connected to and connected to the light source module; and provided on the connecting and fixing portion. And a light-emitting part that is supplied with power from the light source module through the connection part and is turned on.

  The present invention can provide a connecting device that holds an LED module and maintains the light continuity of the LED module.

Next, the expansion connection unit 800 shown in FIG. 18 will be described.
The expansion connection portion 800 includes an expansion connection substrate portion 810 (also referred to as a connection fixing portion) fixed to the attachment member 600, an expansion connection portion 520 connected to the LED module 221, and an LED module via the expansion connection portion 520. An extended LED 530 that emits light by electric power supplied from 221 is provided.

The extended connection board portion 810 has a substantially rectangular shape, and the C side 811 facing the LED module 211 is restricted to be larger than the short length B (shown in FIG. 8) of the LED module 211, and is substantially perpendicular to the C side 811. The D side 812 positioned in such a relationship is formed to have a dimension that allows a plurality of extended LEDs 530 to be arranged in a straight line.
In addition, a connection portion 222e is arranged to protrude from the extended connection portion 520 to the C side.
In addition, an expansion fixing hole 540 for fixing to the attachment member 600 is formed in the expansion connecting portion 810 at the center of the diagonal of the four expansion LEDs 530 adjacent in the horizontal and vertical directions.
A wiring pattern 820 for supplying power to the expansion LED 530 is formed on both sides of the expansion main body 520, and the wiring pattern 820 is formed so as to maintain an insulation distance between the expansion LED 530 and the expansion fixing hole 540. .

  In the present embodiment, the LED module 221 can be expanded and the lighting area can be increased by connecting the LED module 221 with the expansion coupling unit 500 including the expansion unit 510.

  In the present embodiment, three extended LEDs 530 are mounted in the longitudinal direction. However, the length of the substrate and the number of extended LEDs 530 are appropriately changed depending on the relationship with the length of the mounting member 600 and the like. be able to.
