DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting window which is installed near a doorway of a building such as a house and has a suitable lighting function.

[0002]

2. Description of the Related Art In many cases, a space for lighting is provided on a door such as an entrance or a doorway of a house. The reason is that in the daytime, natural light is taken in from the outside through this space to illuminate the inside of the entrance or the entrance. On the other hand, lighting equipment is indispensable in the entrance and the entrance of the entrance and the exterior to illuminate the feet at night. Therefore, in the related art, lighting fixtures are provided on the outside and inside together with the lighting space.

[0003]

Conventionally, as mentioned above, a space for lighting is provided on the entrance or the entrance, and the outdoor and indoor sides of the entrance or the entrance are illuminated at night. Lighting equipment is provided. For this reason, the lighting fixtures must be installed outside and inside in addition to the installation space between the columns, and furthermore, the installation locations must be secured, so that the cost is high and the design is troublesome. In addition, even if there is a window for lighting at the top of the stairs, lighting equipment for illuminating the stairs must be separately installed at night, so in such a case, the installation location of the lighting equipment must be considered, Housing design is cumbersome.

[0004] It is an object of the present invention to add a lighting function in which a window for daylight takes in natural light indoors during the day without being blocked by a built-in lighting device, and radiates the illumination light both indoors and outdoors at night. It is an object of the present invention to provide a lighting window having a lighting function having both functions as a lighting device and two lighting devices.

[0005]

According to the present invention, a window frame for forming a skylight, a light transmissive panel fitted outside the window frame, and an inner peripheral surface of the window frame are arranged. A lighting window having a lighting function is constituted by the lighting fixture and a light-transmitting cover that shields the lighting fixture from the space on the indoor side.

According to the lighting window having the lighting function of the present invention, since the built-in lighting fixtures are arranged along the four-periphery frame, the lighting window does not block light.
Therefore, in the daytime, natural light can be taken indoors from outside. Also, by illuminating the lighting equipment at night, both the indoor and the outdoor can be illuminated. Therefore, when installed above the door of the entrance or the entrance, both the inside and the outside of the entrance or the entrance can be illuminated. Therefore, there is obtained an advantage that it is not necessary to provide a lighting device on both the inside and the outside, and an advantage that cost of construction cost can be reduced is obtained.

[0007]

1 and 2 show an embodiment of the present invention. In the figure, reference numeral 10 denotes a skylight having a lighting function according to the present invention. A lighting window 10 having a lighting function according to the present invention is used by being fitted into an opening formed in a frame 20 of a building. In the example shown in FIGS. 1 and 2, FIG.
As will be apparent from FIG. The window frame 11 is formed in a ring shape.
2 is fitted. As the light transmissive panel 12, for example, ground glass can be used, and the light transmissive panel 12 is sealed and held on the window frame 11 by an airtight material 12A.

A lighting fixture 13 is mounted along the inner peripheral surface 11A of the window frame 11. In this example, a case where a round fluorescent tube is used as the lighting fixture 13 is shown. A light transmissive cover 14 is mounted on the indoor side surface of the window frame 11. Light transmissive cover 14
Can be constituted by, for example, a milky white light-transmitting plate 14A and a ring-shaped frame 14B attached to the periphery of the light-transmitting plate 14A. In the ring-shaped frame 14B,
In this example, a case is shown in which a flange 14C is formed to project from the outer periphery, and a screw 14D is screwed into a hole formed in the flange 14C to mount the light-transmitting cover 14 on the window frame 11. Therefore, by removing the screw 14D, the light transmissive cover 14 can be removed from the window frame 11, and the replacement or maintenance and inspection of the lighting fixture 13 can be performed.

As shown in FIG. 1, the light-transmitting cover 14 is mounted on the window frame 11 as a structure.
Instead of using C, a structure in which the frame 14B is held down by a holding metal fitting is also conceivable. In this case, the screw for holding down the holding member may be a screw with a knob, and the holding member may be held down by rotating and holding the knob without using a tool. In addition, the opening and closing structure may be formed by a hinge type, and may not necessarily be detachable.

FIGS. 3 and 4 show a modified embodiment of the present invention. This embodiment is the same as the embodiment of FIGS. 1 and 2 in that it has a round window structure and a structure in which the light transmissive panel 12 is fitted on the outdoor side, but the embodiment of FIGS. The difference from the example is the structure of the light transmissive cover 14 fitted on the indoor side. The light transmissive cover 14 shown in FIGS. 3 and 4 has a structure in which a light transmissive resin plate is formed in a ring shape, the outer peripheral surface of the ring shape is concave, and the lighting fixture 13 is stored in the concave surface. . Further, the light transmissive cover 14 is engaged with the engaging portions 11B and 11C provided on the window frame 11, and the light transmissive cover 14 is detachably supported on the window frame 20 by this engagement. The reason for providing the light transmissive cover 14 is as follows.
This is for preventing dust and the like from the indoor side from adhering to the lighting fixture 13. Therefore, even the configuration of the light-transmitting cover shown in FIGS. 3 and 4 can sufficiently achieve the object.

FIGS. 5 and 6 show still another embodiment of the present invention. In this embodiment, a case of a square window structure is shown. Therefore, in this embodiment, the lighting fixture 13 uses a linear fluorescent tube. The cross-sectional shape of the window frame 11 is substantially the same as that of FIG. 1, but the shape of the frame is rectangular as shown in FIG.

[0012]

As described above, according to the lighting window having the lighting function according to the present invention, the light transmissive panel 12 is fitted on the outdoor side, and the light transmissive cover 14 is also fitted on the indoor side. In the daytime, natural light can be taken in from outside. Therefore, the interior of the entrance or the entrance can be illuminated with natural light. Also, when installed on the top of a stair or the like, the stairs can be illuminated by natural light in the daytime.

Further, by illuminating the lighting equipment 13 at night, it is possible to illuminate the outdoors and indoors. Therefore, the feet can be illuminated without specially providing a lighting device outside and inside the entrance or the entrance. In addition, even when the lighting device is installed above the stairs, the stairs can be illuminated without separately installing a lighting device, and the lighting device can be used as both a lighting device and a lighting device. Further, since it is not necessary to install the lighting equipment inside and outside the entrance or inside and outside the entrance, there is an advantage that the installation cost of the lighting equipment can be reduced.
