Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to mounting a louver for a lighting fixture.

[0002]

[Prior art]

 3 and 4 show the attachment of a plurality of conventional louvers for lighting equipment. The configuration is such that a plurality of lighting fixture louvers 10 and 20 located below a light source (not shown) for controlling light from the light source and the bottom end portions of the plurality of lighting fixture louvers 10 and 20 are provided. It is composed of connecting portions 60, 70 which are connected to each other, and fastening portions 30, 40, 50 which fix the connecting portions 60, 70 to form the louver 10, 20 for the lighting fixture. Here, a fluorescent lamp is generally often used as a light source. Further, the fastening portions 30, 40, 50 include a fastening piece 30 provided at the end of the louver 10 for one lighting fixture and a fastening piece 40 provided at the end of the louver 20 for the other lighting fixture. Are fixed by screws 50 to form luminaire louvers 10 and 20 that are integrated with each other.

[0003]

[Problems to be solved by the device]

 The problem to be solved by the present invention is that it is difficult to bring the connecting parts into close contact with each other even if they are fixed by the fastening parts, a gap is generated in the connecting parts, light from the light source leaks, and The light distribution performance is not obtained, and the appearance is poor due to the leakage of light, and the purpose of the present invention is to prevent multiple light louvers from leaking light from the light source. Another object of the present invention is to provide a lighting fixture that is difficult to integrate.

[0004]

[Means for Solving the Problems]

 According to the present invention, a plurality of lighting fixture louvers that are located below a light source and control light from the light source, a connecting portion that connects between lower end portions of the plurality of lighting fixture louvers, and the connecting portion are fixed. And a joint for joining the plurality of louvers for lighting fixtures by this fastening, and the positions of the joint and the joint are horizontally shifted. It is characterized by being configured.

Further, the fastening portion may be provided near the joint portion.

[0006]

[Action]

 According to the present invention, since the positions of the connecting portion and the connecting portion of the plurality of louvers for lighting fixtures are horizontally shifted, it is difficult for the light from the light source to leak and the desired light distribution performance is obtained. In addition, it has the effect of preventing light from leaking and improving the appearance.

Further, since the fastening portion is provided in the vicinity of the joint portion, there is an effect that the joint portions of the plurality of lighting device louvers can be joined more reliably.

[0008]

【Example】

 FIG. 1 shows an embodiment of the present invention. The configuration is such that a plurality of lighting fixture louvers 1 and 2 located below a light source (not shown) for controlling the light from the light source and the lower end portions of the plurality of lighting fixture louvers 1 and 2 are arranged. The connecting portions 60, 70 which are connected to each other, and the fastening portions 3, 4, 5 which are provided in the vicinity of the connecting portions 6, 7 which fix the connecting portions 60, 70 to form the louvers 1 and 2 for the lighting fixture, which are integrated with each other. The joining parts 6 and 7 to which the plurality of louvers 1 and 2 for lighting fixtures are joined by this fastening are provided, and the positions of the connecting parts 60 and 70 and the joining parts 6 and 7 are horizontally shifted. It consists of

Here, the fastening portions 3, 4, 5 are provided on the fastening piece 3 provided at one end of the lighting fixture louver 1 and at the other end of the other lighting fixture louver 2. The fastening piece 4 and the fastening piece 4 are fixed by a screw 5 to form an integrated louver 1 and 2 for a lighting fixture.

The difference from the conventional example is that the joining portions 6 and 7 are formed by cutting a part of the lighting fixture louver 2 and adding it to the lighting fixture louver 1, that is, the connecting portions 60 and 70. They are formed by horizontally shifting the positions of the joints 6, 7 and forming the fastening parts 3, 4, 5 near the joints 6, 7.

As described above, since the positions of the connecting portions 60, 70 and the joint portions 6, 7 of the plurality of louvers 1 and 2 for lighting fixtures are horizontally shifted, it is difficult for the light from the light source to leak. In addition to providing the desired light distribution performance for the first time, the appearance also makes it difficult to leak light, and the appearance is good.Because the joints are provided near the joints, the joints of multiple louvers for lighting equipment can be more accurately Can be joined.

[0012]

[Effect of device]

 According to the present invention, a plurality of lighting fixture louvers that are located below a light source and control light from the light source, a connecting portion that connects between lower end portions of the plurality of lighting fixture louvers, and the connecting portion are fixed. And a joint for joining the plurality of louvers for lighting fixtures by this fastening, and the positions of the joint and the joint are horizontally shifted. Since it is configured, the light from the light source does not easily leak, the desired light distribution performance is obtained, and the appearance has a remarkable effect in that the light does not leak easily.

Further, since the fastening portion is provided in the vicinity of the joint portion, there is a remarkable effect that the joint portions of the plurality of lighting fixture louvers can be joined more reliably.
