Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lighting device provided near a window of a building.

[0002]

2. Description of the Related Art Even if the windows of a building reach the area stipulated by the Building Standards Law, there are light-blocking objects such as other buildings near the windows, and there are balconies and common passages in apartment buildings outside the windows. When there is such a large corridor or the like, or in the case of a room facing north, the amount of light incident on the room is insufficient, the room is dark, and illumination is required even in daytime.

For this reason, conventionally, a roof window or a roof is provided with a skylight, or a light collector is provided, and daylight is drawn into the room with an optical fiber to replenish the amount of incident light, but all of them are expensive. Moreover, in the latter case, the structure is complicated.
It is to be noted that the light amount is adjusted by a louver, but this is for adjusting the amount of incident light, and cannot be increased.

[0004]

The first object of the present invention is as follows.
The invention of the present invention easily incorporates a large amount of daylight over a wide area of the room to increase the brightness of the room, and has a simple structure,
It is an object to be able to provide at low cost.

Another object of the present invention is to make it possible to retrofit an existing object located in front of a window in addition to the object of the first aspect of the present invention.

A third object of the present invention is to make it possible to take in daylight in a desired direction in a room in addition to the objects of the first or second invention.

[0007]

According to a first aspect of the present invention, in order to solve the above-mentioned problems, a horizontally long reflecting member is attached to an object located in front of a window so as to face the window. It is a feature. The reflection in the specification of the present application means the reflection of light.

[0008] Daylight is reflected by a reflecting member attached to an object to be mounted located in front of a window such as a balcony or a garden, and enters the room through a window glass or a window opening. For this reason, even if there are the above-mentioned shades, balconies, large corridors, etc., it is possible to take in daylight into the room, and even in a room facing north, take in skylight that does not include direct sunlight during daylight. And the amount of incident light can be replenished, and the room brightness increases. When the reflecting member is a point mirror like a hand mirror, the amount of incident light is small, and when the reflecting member is vertically long, daylight cannot be widely incident. The amount of light is large, and the light can be widely entered into the room. By the way, the brightness of artificial lighting in the room is usually 500-1,000 lux, while daylight has a brightness of 5,000-50,000 lux even on a cloudy day, and part of it is used. Just alone is very effective.

According to the first aspect of the present invention, there is no limitation as to whether the reflecting member is directly or indirectly attached to the object to be mounted. It is preferable to attach to an object to be attached via a member. In this way, there is no need to form a dedicated mounting object provided with mounting means in advance, and it is sufficient to mount a mounting member on an existing mounting object and mount a reflection member on this.
Existing attachments can be used.

In the first or second aspect of the present invention, it is not limited whether or not the mounting angle of the reflecting member is constant. However, as in the third aspect of the present invention, the reflecting member can adjust the inclination angle freely. Preferably, there is.

According to the third aspect of the invention, by adjusting the inclination angle of the reflecting member, daylight can be introduced in a desired direction, for example, only at the window or in the interior of the room.

That is, as shown in FIG. 12, the reflection member 4 composed of a reflection plate is formed in a mountain-shaped cross section, and is formed in a horizontally long shape, specifically, in a horizontally long band shape. Specifically, as shown in FIG. 31, the longitudinal distance L2 of the reflecting member 4 made of a reflecting plate is set to be equal to or approximately equal to the width W of the window 1, and as shown in FIGS. A plurality of reinforcing plates 40, 40 on the back
Are fixed at intervals and the lower edge 4 of each reinforcing plate 40 is fixed.
0a is formed in a concave arc shape in contact with the convex arc face plate 60, and a pair of bolt insertion holes 41 and 42 are formed on the left and right sides of the reflection member 4, and near the top and on the inclined portion. 13 and 14, a symbol a indicates a partition plate from an adjacent balcony in an apartment house, and the reflecting member 4 formed of the reflecting plate of the fifth embodiment in FIGS. 29 and 31 is indicated by a one-dot chain line. is there.

Then, rubber packings 65 'and 65' are applied to the left and right outer surfaces of the handrail 23, respectively.
The bottom of the concave portion 62 of each reinforcing plate 61 is in contact with the upper surface of the handrail 23, and each bolt 57 is screwed so that the pressing piece 65 is strongly pressed against the inner surface of the handrail 23. Subsequently, for example, the solid line in FIG.
As shown by the two-dot chain line, the reflecting member 4 is inclined at a desired angle, the lower end edge 40a of each reinforcing plate 40 is attached to the convex arc face plate 60, the bolt 55 is inserted into each bolt insertion hole 41, and the screw hole 39c is inserted. , 39d, and 39e, and a bolt 56 is inserted into each of the bolt insertion holes 42, and is screwed into a screw hole corresponding to the bolt 56 among the screw holes 39f, 39g, and 39h. Since the distance between the bolts 55 and 56 inserted into the bolt insertion holes 41 and 42 is constant, the screw holes 39c and 39f, 39d and 39g,
The intervals between 39e and 39h are made constant so as to correspond to the bolts 55 and 56. Thus, screw hole 3
The tilt angle of the reflecting member 4 is adjusted by screwing the bolts 55 and 56 to any of 9c to 39h. The third
Unlike the embodiment, the second row of preliminary screw holes 39c
In this embodiment, the bolt insertion hole 4 is not provided due to the presence of the vertical rod as in the third embodiment.
No mismatch occurs between the bolt insertion holes 41 and 42 and the screw holes 39c to 39h.
