Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to a composite solar light transmission system that allows sunlight to be transmitted into a building as two types of sunlight: concentrated and non-concentrated.

[Prior Art] Conventionally, when introducing sunlight into a building from some sunlight daylighting devices, as shown in FIG. The condensed light is transmitted into the building 1 via a transmission line 5 in a medium and is emitted. Furthermore, as shown in FIG. 4(B), there is also a device in which the light is transmitted from the plane mirror 3 through an aerial transmission path 6 into a building and then emitted. Furthermore, as shown in FIG. 4(C), sunlight is collected by a condensing device 4 made up of two curved mirrors, and the collected light is transmitted into the building via an aerial transmission line 6 and then emitted. Some have made it so.

[Problem to be solved by the invention] Conventionally, sunlight is transmitted as concentrated light or non-concentrated light, but in all of these transmissions only tfHi, either concentrated or non-concentrated, is transmitted. Only. For this reason, when illuminating with transmitted light, the method of producing illumination is limited by using one type of light, and it is not possible to sufficiently change the illumination to suit various purposes. Furthermore, if you try to install the optical transmission devices shown in Figure 4 (A) and (B) side by side in order to provide two types of illumination, for example, the space for installation will have to be enlarged, and the installation work will be difficult. It's not easy.

Therefore, the present invention provides a condensing device in the aerial transmission line so that a part of the sunlight on the aerial transmission line can be condensed and transmitted by the concentrating device, so that two types of light can be transmitted simultaneously. The aim is to transmit composite light so that different lighting can be applied to multiple locations.

[Means for Solving the Problems] The present invention achieves the above object, and includes sending sunlight collected by a non-concentrating daylighting device to an aerial transmission line,
A condensing device for concentrating part of the daylight is installed in this aerial transmission line, and the condensed light is transmitted in the air or in a medium, and the remaining daylight is transmitted through the aerial transmission line. This is a composite transmission method for sunlight.

When transmitting condensed light using two types of transmission methods, at least two concentrators that condense part of the sunlight are provided on the aerial transmission path of the sunlight, and the condensed light is collected from one condensing device. The light beam is transmitted through the air, and the condensed light from another condensing device is transmitted through a medium.

[Operation] In the above means, sunlight is collected by a part of the non-concentrating daylighting device and made to enter the aerial transmission line. Then, a condensing device is installed on the aerial transmission line to condense some of the sunlight, and the condensed light is transmitted in the air or through a medium, so that the condensed light and the non-condensed light that does not enter the concentrator are separated. Two types of data can be transmitted. Note that, unlike other condensed aerial transmissions and condensed aerial transmissions, non-concentrated aerial transmission can transmit scattered light in addition to direct light, making it possible to produce different types of lighting.

In addition, when at least two light concentrators are installed on the aerial transmission path of the daylight, one of the condensed lights is transmitted in the air, and the other condensed light is transmitted in a medium, the condensed light is further decondensed from the aerial transmission path of the daylight. It can transmit light, making various types of illumination possible. Furthermore, by making each transmission path separate, it can be used for lighting multiple locations.

[Example 1 A first embodiment of the present invention will be described with reference to FIG.

An aerial transmission line 2 is provided in a building 1, and a plane mirror 3 is arranged at an angle opposite to the entrance of the aerial transmission line 2. Direct sunlight is reflected by the plane mirror 3 and enters the aerial transmission line 2. It is designed to be incident. It should be noted that not only the direct light of sunlight (scattered light) also enters the aerial transmission line 2.

A condensing device 4 made of, for example, a convex lens is provided within the aerial transmission line 2 to condense a part of the sunlight within the aerial transmission line 2 . The condensed light condensed by the condensing device 4 is transmitted to a predetermined position through a transmission path 5 in the medium. Also, of the sunlight in the aerial transmission line 2, that which does not enter the condensing device 4 is transmitted along the aerial transmission line 2 as non-condensed light.

Next, a second embodiment of the present invention will be explained with reference to FIG.

In this embodiment, like the first embodiment, non-condensed daylight is made to enter the aerial transmission line 2 through the plane mirror 3. A light condensing device 4 is provided in the aerial transmission line 2, which is made by combining two curved mirrors as shown in FIG. ing. The condensed light from the condensing device 4 is transmitted through an aerial transmission line 6. Note that a plane mirror is provided at a part of the bent corner of the aerial transmission line 6 so that the transmission direction can be changed. Other structural functions are the same as in the first embodiment.

Next, a third embodiment of the present invention will be described with reference to FIG.

In this embodiment, as in the first embodiment, non-condensed daylight is made to enter the aerial transmission line 2 through the plane mirror 3. A condensing device 4a consisting of a convex lens in the aerial transmission path 2,
A condensing device 4b consisting of two curved mirrors is provided, and a part of the daylight in the aerial transmission line 2 is separately condensed by the two condensing devices. The condensed light condensed by the condenser 4a is transmitted through the medium transmission line 5, and the condensed light condensed by the condenser 41) is transmitted through the aerial transmission line 6. It has become.

Further, other non-condensed light that is not focused within the aerial transmission line 2 is transmitted along the aerial transmission line 2 as is. For this reason, the third
In the embodiment, three types of illumination light can be transmitted, and by separating the tributaries of the transmission path, it can be used for illuminating multiple locations.

In the above, two condensing devices are installed in the aerial transmission line 2, but it is also possible to provide three or two condensing devices, and in that case, the condensed light from each concentrating device can be It can be transmitted to any location via a transmission line or an aerial transmission line.

[Effect of the invention 1] In the present invention, a light condensing device is provided in the aerial transmission path of the great sunlight, and a part of the sunlight is focused and transmitted in the air and/or in the medium, so it is not a point light source. Since two types of light sources, a surface light source and a surface light source, can be obtained, and scattered light can also be used, the number of lighting effects can be increased. In addition, since some non-condensing daylighting devices can be used to emit different light sources, the device does not need to be large-sized, which is advantageous in terms of layout space. Furthermore, by changing the transmission paths of various types of light, it is also possible to irradiate multiple locations.
