Description

  The present invention relates to a lighting fixture embedded and installed in a ceiling of a building, and particularly to a mounting lighting fixture suitable for a downlight that illuminates a floor below.

  The applicant of the present application previously described in Patent Document 1 below a reflector having a polyhedral mirror surface on the inner surface to diffusely reflect light from a lamp, and a metal halide lamp socket for mounting the reflector on a top plate portion. Also disclosed is a downlight device in which the socket is replaceable with an existing socket so that the reflector and the socket fit inside the fixed reflector of the existing downlight.

This downlight fixture uses the existing downlight body as it is, so there is no need to renovate the ceiling and the image of the interior can be maintained as it is. There is an advantage that power consumption can be reduced, lighting efficiency can be improved, heat generation can be reduced, and air conditioning efficiency in the building can be improved.
JP 2003-151310 A

  The present invention was completed by taking advantage of the reflection plate having a polyhedral mirror surface on the inner surface, and conceiving an application to a fixture for newly attaching a downlight to a ceiling of a building.

  And even if this downlight is newly installed on the ceiling of a building, its mounting position is often located on a high ceiling, so that it is assembled and mounted, and maintenance such as lamp replacement and cleaning after mounting is performed. However, there is a problem that it takes time and effort.

  In addition, the insects easily enter the downlight which is usually mounted at a high position due to the insect collecting action of the halide lamp, and it takes time to remove the invading insects.

  The problem to be solved by the present invention is to provide a lighting fixture that facilitates assembling from the ceiling and maintenance for lamp replacement and cleaning from the ceiling even if the ceiling is high.

  Another object of the present invention is to provide a structure for preventing insects from entering the inside of a glass surface provided on the lower surface, in addition to facilitating assembly and maintenance from above the ceiling.

  The present invention provides a socket member including a socket cover and a top plate that cover a socket of a light source lamp, a reflector plate that diffusely reflects light of the light source lamp attached to a position below the socket cover of the socket member, and the socket member. An attached frame, a lower surface cover attached to the lower end of the frame, and a lighting fixture having respective members of light-transmitting glass disposed inside the lower surface cover, wherein the respective members are: It is characterized by having a support member that is assembled by a detachable attaching means and that supports the light transmitting glass by providing a gap between the inner surface of the lower surface cover and the lower end of the reflection plate.

  The lighting fixture of the present invention is easy to install, can perform all maintenance work from above the ceiling, and can effectively prevent invasion of small insects into the interior.

  Hereinafter, the present invention will be specifically described based on an embodiment shown in the attached drawings in which the present invention is applied to a downlight device.

  In FIG. 1 showing an assembly member of a downlight device according to the present invention, a downlight device 10 according to the present invention is a light source lamp as shown in FIG. 2 showing a cross-sectional structure of the downlight device after assembling the respective members. A socket member 1 for covering a socket 6 (not shown), a reflector plate member 2 attached below the socket member 1, a frame member 3 attached to the outer periphery of the socket member 1, and a frame member And a ring-shaped lower cover 4 provided at the lower end of the lower cover 3.

  Further, the socket member 1 includes a socket cover 11 that covers the socket 6 of the light source lamp (not shown) and a top plate 12.

  The reflecting plate member 2 includes a reflecting plate 21 formed of a cap-shaped octahedron having a regular cross section of an equilateral hexagon, a mounting plate 22 for the reflecting plate 21, and a cylindrical body 23 mounted on an upper surface of the mounting plate 22. And suspended by attaching the cylindrical body 23 to the socket cover 11.

  The material of the reflecting plate 21 is aluminum, and the inner reflecting surface is mirror-finished by coating titanium and silicon on the surface of aluminum.

  The shape of the reflecting plate may be any shape such as a spherical shape and a polyhedral shape. In the case of a polyhedral shape, it is preferable to use an 18- or more polyhedral shape from the viewpoint of improving the reflection efficiency.

  The frame body 3 is for attaching the entire downlight device 10 to the ceiling T and for attaching the lower surface cover 4, and includes an attachment portion 31 of the socket member 1 to the top plate 12, an outer frame 32, and the outer frame. As shown in FIG. 1, the support member 33 has a support member 33 extending outward and a ring 34 attached to a lower end of the outer frame 32.

  Then, the support member 33 developed outward is placed on the back surface of the ceiling T, and the entire downlight device 10 is suspended on the back surface of the ceiling T.

  When the downlight device 10 is suspended from the ceiling, depending on the condition of the ceiling to be mounted, a flange 35 provided on the lower surface of the outer frame 32 is used in combination, and the ceiling is sandwiched between the flange 35 and the support member 33 to downlight the device. Suspension of the whole 10 on the ceiling side can be ensured.

  The lower surface cover 4 is detachably attached to a lower portion of the outer frame 32 of the frame body 3 by an arbitrary attaching means, and a gap through which air can flow between the lower surface cover 4 and the lower end of the reflection plate 21 is provided inside. It supports a translucent wavy glass 5 for reducing glare.

  Specifically, as means for attaching the lower cover 4 to the outer frame 32, as shown in FIGS. 2 and 3, a spring pin 41 is detachably locked to a locking portion 32 a provided on the outer frame 32. Such a pinning means can be used.

  Further, the lower cover 4 is provided with a gap through which air can flow between the lower end of the reflection plate 21 and the translucent rippling glass 5 to partially support the translucent rippling glass 5 inward thereof. The support member 42 is provided in a wavy shape. In this way, insects can be prevented from entering the downlight device 10.

  Except for the attachment of the lower cover 4 and the lower end of the outer frame 32, the downlight device 10 can be easily assembled and attached from behind the ceiling by optionally using screws.

  In addition, because it can be easily disassembled in part, maintenance is simplified, and the inconvenience of insects, which has been the most troublesome in the past, can be prevented, and the number of times of maintenance itself can be reduced. .

  The lighting fixture of the present invention can be applied not only to a downlight fixture mounted on a ceiling but also to a wall surface or a floor surface only by using a fixing member as a mounting member.

3 shows an assembly member of the downlight device according to the present invention. 2 shows a cross-sectional structure of the downlight device after assembling each member. The procedure for attaching the lower surface cover to the frame is shown.
