Description

  The present invention relates to an installation mechanism of an embedded lighting device installed on a ceiling of a clean room such as a pharmaceutical factory or a cosmetic factory.

  Some clean rooms have a high ceiling with a ceiling height of about 8 m based on the concept of constructing a space in which production equipment can be flexibly moved in the future, such as layout changes.

  In such a high ceiling space, it is difficult to perform lamp replacement of a lighting fixture installed on the ceiling using a stepladder.

  There is also a so-called auto-lifter type lighting fixture that can raise and lower the lighting fixture when replacing the lamp, but such a lighting fixture is difficult to flexibly respond to future layout changes and is expensive. At the same time, there is a problem that dust falls when the lighting apparatus is lowered.

  For this reason, in a clean room, there is a need for a lighting fixture that can perform lamp replacement in the ceiling, can be performed at low cost, and can be safely performed.

Thus, as described in Patent Document 1 and Patent Document 2, for example, various proposals have been made to enable lamp replacement in a ceiling of a clean room or the like.

  In this way, various lighting fixtures that can be replaced in the ceiling in a clean room have been proposed in the past. Is also a big burden.

Further, in the conventional apparatus, when replacing the lamp in the ceiling, it is necessary to remove a heavy part and place it in an appropriate place in the ceiling, and it is not always possible to safely replace the lamp.
The present invention aims to solve such problems.

In order to solve the above-described problems, in the present invention, first, a lighting fixture support member is suspended by a suspension bolt below a ceiling support steel material, and the lighting fixture main body is supported below the lighting fixture support member. In the lighting fixture composed of a lamp, holder, shade and transparent plate, the transparent plate is separated from the shade and supported by a frame to constitute a transparent plate panel. The panel is supported by a suspension bolt below the lighting fixture support member and hermetically integrated with the ceiling plate, and the lighting fixture body composed of a lamp, a holder, and a shade is flexibly suspended below the main body support member. And the tip side of the shade is supported close to the transparent plate, and the interval between the main body supporting member and the transparent plate panel is such that the luminaire main body is attached to the lamp. Possible intervals raised to a height that allows the conversion, in the above body supporting member proposes installing mechanism embedded type lighting apparatus in which a temporary support member which allows supporting the intermediate portion of the flexible suspended member.

  In the present invention, the lighting fixture support member is suspended by the suspension bolt below the ceiling support steel material, and the lighting fixture main body support member is suspended by the suspension bolt below the illumination fixture support member.
