きる。 As shown in the figure, this sunlight lighting device 1 is composed of a solar tracking reflector 2 and a light distribution reflector 3 installed outdoors. The solar tracking reflector 2 is a plane mirror having an appropriate shape and size, and the solar tracking reflector 2 is a plane mirror having an appropriate shape and size.
The light distribution reflector 3 reflects the sunlight L that is exposed to sunlight for the longest time, such as on the roof, and as described below.
be installed in a place where it can be incident on the Further, on the reflecting surface 21 of the sun tracking reflector 2, a plurality of infrared reflecting plates 4, 4, . The infrared reflecting plates 4, 4, . . . are made by attaching a film that reflects infrared rays, so-called heat rays, well to a glass plate, and almost all other wavelengths of light are transmitted therethrough. In other words, by transmitting sunlight L through the infrared reflecting plates 4, 4...
Most of the heat rays contained in sunlight L can be removed.
一方、配光反射鏡３は適宜な形状と大きさを有

窓Ｗから室内Ｒのできるだけ広い範囲に反射光を
入射し得る位置に設置される。この配光反射鏡３
には偏向角自動制御装置Ｔが備えられている。 On the other hand, the light distribution reflector 3 is a plane mirror having an appropriate shape and size, and is attached to a supporting member 5 such as a wall or a specially provided column, and can be turned as described later to cover as much of the room R as possible from the window W. It is installed in a position where reflected light can be incident over a wide range. This light distribution reflector 3
is equipped with an automatic deflection angle control device T.

に太陽光を取入れることができる。 With the above configuration, the solar tracking reflector 2 is automatically deflected by the solar automatic tracking device S according to the direction and altitude of the sun, and the reflected sunlight L is always made to enter the light distribution reflector 3. The light distribution reflector 3 is automatically deflected by the automatic deflection control device T.
The sunlight L from the sun tracking reflector 2 is reflected again and made to enter a preset range of the room R through the window W. That is, irrespective of the direction and altitude of the sun, in other words, irrespective of the season or time, the direction of the light distribution reflector 3 can be controlled by the automatic deflection angle control device T to appropriately introduce sunlight into the room R. .
次に、第２図に示した太陽追尾反射鏡２の部分
側断面概略図により赤外線反射板４，４…の機能
を説明する。 Next, the functions of the infrared reflectors 4, 4, . . . will be explained with reference to a partial side cross-sectional schematic diagram of the sun tracking reflector 2 shown in FIG.
図で示す様に太陽の高度が高く、太陽光Ｌが大

陽光L1，L1が反射の前か後かに各赤外線反射板
４，４を透過したことになる。即ち太陽光L1，
L1には前述の如く熱線が殆ど含まれない。 As shown in the figure, when the altitude of the sun is high and sunlight L forms a large angle and enters the solar tracking reflector 2 and is reflected, sunlight L 1 , This means that L 1 is transmitted through each infrared reflecting plate 4, 4 either before or after reflection. That is, sunlight L 1 ,
As mentioned above, L 1 contains almost no heat rays.
又、太陽の高度が低く、太陽光Ｌが小さな角度
を成して太陽追尾反射鏡２へ入射し反射される場
合には、図中縦線を施した狭い範囲の太陽光L2，
L2が熱線を殆ど含まないことになる。 In addition, when the altitude of the sun is low and the sunlight L forms a small angle and enters the solar tracking reflector 2 and is reflected, the sunlight L 2 ,
This means that L 2 contains almost no heat rays.
従つて太陽追尾反射鏡２の反射面２１に赤外線
反射板４，４…を突設することにより、南中時の
太陽高度が高い夏期ほど熱線を殆ど含まない太陽
光Ｌを室内Ｒへ取入れることが可能となる。 Therefore, by protruding infrared reflectors 4, 4, etc. on the reflective surface 21 of the sun tracking reflector 2, sunlight L, which contains almost no heat rays, can be taken into the room R in the summer when the sun's altitude is high at mid-sunset. becomes possible.

は36％となる。 The proportion of heat rays removed from the sunlight L, that is, the proportion of sunlight L that passes through the infrared reflectors 4, 4, etc. when entering and reflecting on the sun tracking reflector 2, is the same under conditions such as the angle of incidence and reflection. If so, it is determined by the ratio of the protrusion amount a of the infrared reflectors 4, 4, . . . and the mutual spacing d.
For example, the sun tracking reflector 2 reflects sunlight L from the sun at an altitude of 76 degrees (sunlight intensity at midsummer on the summer solstice in Sapporo) to the light distribution reflector 3 located 20 degrees below the horizontal plane. It is also assumed that the infrared reflectors 4, 4, . . . can reflect and remove 80% of the heat rays. Under such conditions, the infrared reflectors 4, 4
If the ratio a to d of ... is 1 to 2, the proportion of sunlight L that passes through the infrared reflectors 4, 4 ... is 100%,
The percentage of heat rays removed is 80%. Furthermore, when the ratio of a to d is 1:3, the ratio of heat rays removed is 58%, when the ratio is 1:4, it is 45%, and when the ratio is 1:5, it is 36%.

能である。 If the ratio of heat rays to be removed is set to a large value, the ratio of heat rays to be removed will increase accordingly even in winter when the solar altitude is low, when heat rays should not be removed. Taking this into consideration, the protrusion amount a of the infrared reflecting plates 4, 4... and the mutual distance d are set appropriately. However, by rotating the sun tracking reflector 2 within its reflecting surface and controlling the orientation of the infrared reflectors 4, 4... with respect to the sunlight L incident and reflecting surface of the sun tracking reflector 2, the infrared reflectors 4, 4... It is also possible to change the proportion of sunlight L that passes through 4, 4, .

きる。<Effects of the invention> As described above, according to the solar lighting device of the invention, it can be used regardless of the direction and altitude of the sun, not only when sunlight is not incident due to obstacles, but even when sunlight is incident. In other words, sunlight can be brought into the room as appropriate regardless of the season or time of day. Moreover, since the ratio of heat rays included in the sunlight to be taken in can be set appropriately, a more comfortable sunlight environment can be created.
