  The present invention relates to a mounting structure for a panel lighting fixture for mounting a panel lighting fixture for illuminating the inside of a control panel or the like to a panel such as the control panel.

  Control panels for factory equipment, machine tools, etc. are housed in a box-shaped housing. When the housing door is opened, the door switch is turned on, and accompanying this, inside the panel such as a fluorescent lamp installed in the housing In general, lighting fixtures are turned on (see Patent Document 1, etc.).

Japanese Patent Laid-Open No. 8-149233

  However, in the case of the above conventional example, in addition to the luminaire body and door switch, it is necessary to directly fix the fuse for overcurrent protection, the relay terminal block, etc. to the panel of the housing. There is an annoying problem. In addition, when a fluorescent lamp is used as an in-panel lighting fixture, it is difficult to reduce the size and weight of the fixture because it includes a ballast, and there is a problem that the above work becomes more difficult in this respect.

  The present invention was created in view of the above background, and an object of the present invention is to provide a mounting structure for an in-panel lighting fixture that can be easily assembled into a control panel or the like. .

The mounting structure of the in-panel lighting apparatus according to the present invention is an in-panel lighting apparatus mounting structure for mounting the in-panel lighting apparatus for illuminating the inside of the control panel or the like to a panel of a housing such as the control panel, After the LED lighting fixture is used as the in-panel lighting fixture, the LED lighting fixture and its peripheral parts can be attached to a mounting rail fixed to the panel, and the LED lighting fixture has a linear shape. The LED lighting unit main body, and an end plate having a detachable portion that is a member attached to each end of the LED lighting unit main body in the length direction and engages with the flange portion of the mounting rail. In particular, the LED lighting unit main body has a metal base plate, and irregularities are formed as heat radiation fins on the opposite exposed bottom surface of the mounting rail of the metal base plate.

In the case of the above invention, since the LED lighting fixture and its peripheral parts are fixed to the panel of the housing such as the control panel via the mounting rail, it is easy to attach / remove the panel lighting fixture or the like. . Moreover, since LED lighting fixtures are used as the in-panel lighting fixtures, it is easy to reduce the size and weight of the fixtures compared to the prior art. Therefore , it has become possible to easily perform assembling work, maintenance work, and the like for a control panel such as an in-panel lighting fixture. In particular, since the heat generated from the LED lighting unit main body is effectively radiated by the heat radiating fins, the LED lighting unit main body is prevented from becoming high temperature. Since no special heat dissipating means is required, the cost of the in-panel lighting fixture can be reduced.

  In this case, the mounting rail is preferably fixed to the panel by a magnet seal attached to the bottom surface.

  In the case of the above invention, since the mounting rail is attached to the panel with a magnet seal, it is easy to mount / remove the mounting rail. Work and the like can be performed more easily.

  When the LED lighting apparatus of the above example is used, it is preferable to use one that further includes an intermediate block made of a non-translucent material disposed between the LED lighting unit main body and the end plate.

  According to the above invention, since a part of the light output from the LED lighting unit main body is shielded by the intermediate block, unevenness of the light emitting surface boundary of the LED lighting unit main body is suppressed.

  Further, the LED lighting unit main body may be provided with a power input connector.

  In the case of the above invention, since the LED lighting unit main body is configured to be supplied with power via the power input connector, wiring of the power line is facilitated. Assembling work on the body can be performed more easily.

  As an example of the peripheral component, there is a fuse, a relay terminal block and / or a switch unit for overcurrent protection. In this case, the fuse unit includes a unit main body having an attaching / detaching portion that fits with the flange portion of the mounting rail, a fuse holder that is exposed on the surface side of the unit main body, and a fuse that is detachable from the fuse holder. Use what you have.

  According to the above invention, since the fuse holder is exposed and provided on the surface side of the unit body, it is easy to replace the fuse, and in this respect, the maintenance work of the panel lighting fixtures and the like is further facilitated. It became possible.
