[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a top light, and more particularly to a structure of a top light formed in an upper part of a room where a ceiling surface is stuck below a roof surface through a ceiling space. is there.

[0002]

2. Description of the Related Art A toplight is provided with a light-transmitting portion communicating between a roof surface and a room, and a light-transmitting plate made of transparent glass or the like is fitted into the light-receiving portion, or a light-transmitting portion is provided in the light-receiving portion. There is a so-called skylight in which a window in which an optical material is fitted is arranged.
The amount of light collected from the top light into the room is three times as large as the amount of light collected from a window disposed on the wall surface, and has an effect of reducing photothermal costs. Further, even in a building having a large floor area, by arranging the top light, it is possible to take in natural light to the center of the floor where natural light does not normally reach.

[0003]

However, the top light having the above structure has the following problems. That is, the above-mentioned top light is provided in a lighting part that connects the roof surface and the room. However, on a roof surface such as a rooftop, equipment and the like are arranged, and there are restrictions on a position where a lighting part is formed due to a structural problem of a building or the like. Therefore, the daylighting unit cannot always be provided on the roof surface above the room that needs daylighting. For this reason, the arrangement position of the top light is also limited.

Therefore, the present invention solves the above problems,
It is an object of the present invention to provide a top light capable of lighting at any place inside a building.

It is a sign.

[0006]

[Function] Immediately below the first lighting part provided on the roof surface,
Multiple first reflectors are placed back to back with each other
From the first daylighting section,
The light reflected by the first reflector is directed in different directions
Is reflected. And these first reflectors are
The light incident from one lighting part is reflected to the upper side of the second lighting part.
Each second lighting section is directly above each second lighting section.
Light reflected by one reflector is reflected to each of the second lighting units
Since each of the second reflectors is arranged,
The light incident from the first lighting unit provided at one location
It is divided into multiple directions by reflecting on the reflector of
Light will be collected from the second lighting units provided at multiple locations.
Because

DESCRIPTION OF THE PREFERRED EMBODIMENTS Embodiments of the present invention will be described below with reference to the drawings. FIG. 1 is a diagram illustrating a structure of a top light according to an embodiment of the present invention. In the figure, 1 is the roof surface of the building,
A ceiling surface 2 is attached below the roof surface 1. A ceiling space 3 is provided between the roof surface 1 and the ceiling surface 2, and an interior space 4 is provided below the ceiling surface 2.

On the roof surface 1, a first daylighting portion 1a is formed. The first daylighting unit 1a may be located at any position as long as it does not hinder the structure of the building or the arrangement of the equipment. Further, a translucent plate member 1b is disposed so as to cover the first light-receiving portion 1a.

The ceiling surface 2 has a second lighting part 2
a is drilled. The second lighting unit 2a in the upper position you want to daylight in a room space 4 below, and its multiple position shifted from just below the first lighting unit 1a
Each is provided. That is, the ceiling surface 2
The second daylighting unit 2a is provided. Further, a translucent plate member 2b is provided so as to cover these first light-receiving portions 2a.

In the ceiling space 3, a plurality of sets of two reflectors, a first reflector A and a second reflector B, each of which has a surface for reflecting light on one side of a flat plate, are arranged. I have. Sand
The ceiling space 3 includes a plurality of first reflectors A and a first reflector A.
And the same number of second reflectors B as
It is. Each of the first reflectors A is provided directly below the first daylighting unit 1a and back to back with each other , and is arranged at a predetermined arrangement angle θa with its respective reflection surfaces facing upward. In addition, each of the second reflectors B
Are provided immediately above the respective second daylighting units 2a, and are installed with the reflecting surface inclined downward at a predetermined arrangement angle θb. Further, the set of the first reflector A and the second reflector B is arranged with their respective reflecting surfaces facing each other. With this arrangement,
One reflecting plate A controls light incident from the first lighting part 1a.
Upper side of the second lighting part 2a (that is, the second reflector B)
And the second reflector B is
The light reflected by the reflector A of the second direction to the second lighting part 2a
It becomes reflective.

The respective arrangement angles θa and θb of the first reflector A and the second reflector B are determined by the incident angle of the light collected from the first light collector 1a and the angle of the second light collector 2a. It is determined by the lighting angle of the indoor space 4 and the like. For example,
When the light incident at an incident angle of 90 degrees is desired to be collected in the indoor space 4 at a lighting angle of 90 degrees, the arrangement angles θa and θb of the first reflector A and the second reflector B are set to the ceiling surface 2. Install at an angle of 45 degrees.

Light is collected from the top light having the above structure into the indoor space 4 as follows. First, the light that has entered the first lighting unit 1a at an incident angle of 90 degrees is reflected by the reflecting surface of each first reflecting plate A disposed below the first lighting unit 1a. These first reflectors A are installed at an arrangement angle θa = 45 degrees, and are inserted into each first reflector A.
The emitted light is horizontal to the ceiling surface 2 and each
Are reflected in the direction in which the reflection surface of the first reflection plate A faces . Also, the first reflector A and the second reflector B
Are arranged so that the respective reflection surfaces face each other, so that the light reflected by each first reflection plate A enters each of the second reflection plates B. Since this second reflector B is installed at an arrangement angle θb = 45 degrees, each second reflector
The light incident on B is reflected perpendicularly to the ceiling surface 2. Since each of the second reflectors B is disposed immediately above each of the second lighting units 2a, the light reflected by each of the second reflectors B passes through each of the second lighting units 2a and is indoors. It is lit in space 4. In other words, the first
The light incident on the daylighting unit 1a is
Since the light is taken from the second lighting part 2a at the place
is there.

In the above-mentioned top light, more lighting can be obtained by changing the arrangement angle θa of the first reflector A in accordance with, for example, the irradiation angle of direct solar radiation. In addition, by changing the arrangement angle θb of the second reflector B, the angle at which light is collected into the indoor space 1 changes.

FIG . 2 shows, as another embodiment, three first sheets.
In which the reflectors A are arranged in a triangular pyramid shape. This place
In this case, three second reflectors B are also arranged, and the second lighting part 1b is provided.
Are also provided in three places. For each of the first reflectors A
Arrangement of these second reflector B and second lighting part 1b
The state is the same as in the above embodiment. With this configuration
In such a case, the first lighting section provided in one place of the roof surface 1
1a is incident on three places provided on the ceiling surface 2.
The second daylighting unit 2a starts lighting.

[0015]

[Effect of the invention] As explained above, the top
According to the light source, a plurality of sets of the first reflector and the second reflector
The first lighting section provided in one place
The second daylighting unit that splits the light incident from the
From the room.
