The lighting unit 1 is provided with the lighting protrusion 10 protruding above the ridge surface, and the irradiation unit 20 releases the light taken in from the lighting protrusion to an arbitrary space inside the building; the light guiding mechanism 30 The lighting projection is connected to the irradiation unit to suppress attenuation of light, and the ventilation mechanism 40 is configured to suppress an increase in temperature inside the lighting unit (FIG. 1).

The above-mentioned lighting protrusion 10 is disposed on the top surface to: skylighting The glass 11 has a flat shape and a rectangular shape, and is disposed obliquely with respect to the pedestal at an angle of 45 degrees; the side surface 12 of the protrusion surrounds and supports the circumference of the illuminating glass; and the side glazing glass 13 cuts the protrusion A part of the side is provided to constitute (Fig. 1).

The tilt angle of the aforementioned skylighting glass 11 is relative to the setting The pedestal is inclined at an angle of 45 degrees, but it can be arbitrarily changed as long as the brightness of any space inside the building can be kept constant or more. Although there is a variation due to the installation environment or the required brightness, it is estimated that the brightness of any space inside the building can be kept constant or longer within a range of about 30 to 60 degrees.

The shape of the aforementioned skylighting glass 11 is considered to be the addition of glass. The work cost is a rectangular shape, but it can be changed to a circular shape or the like according to the demand.

Moreover, the larger the size of the above-mentioned skylighting glass 11 is, the more it can be taken in. A lot of sunlight, but preferably at least as large as the diameter of the aforementioned light guiding mechanism 30.

The front side lighting glass 13 is the aforementioned sky surface lighting glass 11 It is difficult to get in, or mainly for taking in the morning light at a small amount or at a low altitude in the evening, so you can take the sun from the morning and the sun at dusk. The position in which the position is located, that is, the direct sunlight of the western position is taken in. When the above-described lighting projection 10 is provided, the position of the side 12 which is the east and west of the above-mentioned lighting projection is included.

In this embodiment, on both sides of the aforementioned lighting projections 10 The side surface lighting glass 13 having a trapezoidal window shape is provided in a certain area, but the design can be changed to other aspects as long as the brightness of any space inside the building can be kept within a certain range or more. For example, it is possible to allow the side surface lighting portion to be provided on the entire surface area or all the side surfaces of the both side surfaces, or the entire circumference surface.

By the outer surface of the aforementioned side lighting glass 13 (outside the building) The side surface is coated with a low-reflection coating layer and subjected to low-reflection processing for suppressing light reflection. However, as long as the same effect can be produced, it can also be applied by coating a low-reflection coating on the inner back surface (the inner surface of the building).

By applying the light back to the inner back surface of the side lighting glass 13 The coating layer is subjected to light reflection processing for transmitting light from one direction and reflecting or blocking light from the other direction, but as long as the same effect can be produced, The outer surface is coated with a light reflective coating for application.

Moreover, it is also allowed to: change the coating of the aforementioned low-reflection coating and The coating of the light-reflecting coating is produced by the film-like raw material having the same effect as the low-reflection processing and the light-reflecting processing described above. A material (a material or a material that transmits light from one direction and reflects or blocks light from another direction) is attached to one side of the side lighting glass, and is subjected to low reflection processing and light reflection processing.

The aforementioned side lighting glass 13 is flat and mesh transparent. Glass, but it can be designed and changed to other glass as long as it can keep the brightness of any space inside the building within a certain range. Also Allow the design to be changed to a material other than glass.

The cylindrical light guide body 32 has a mirror-finished inner peripheral surface. A slit cylinder, but a cylinder formed by mirror-finishing one of the flexible sheets and joining the both end portions without a gap can also be used.

Further, in the configuration of the cylindrical light guide body 32, the aforementioned side surface The portion where the sunlight glass 13 takes in the sunlight is naturally subjected to cutting or the like so as not to block the incidence of light.

The ventilation mechanism 40 is provided by: being disposed in the light guiding mechanism In the outer circumference, the ventilation air is exhausted from the inside of the room (inside the building) to the roof (outside of the building) through the narrow space of the light guiding means, thereby suppressing the lighting. The temperature inside the unit rises. Moreover, due to a storm or the like, a backstop damper is installed so as not to flow into the room from the roof (Fig. 1).

Then, according to Figure 2, the right side is Zhengdong, and the front is right south, left The side is the west, indicating that the sunlight in the morning, the evening, and the daytime is taken in from the lighting projections.

When the sun began to rise in the morning of the East, from the setting The side lighting glass 13 on the side of the east side of the light projection is incident on the direct sunlight S1 (Fig. 2).

Arriving at the aforementioned side lighting glass set on the side of the Oriental position The direct sunlight S1 of 13 is mostly taken into the light guiding mechanism through the side lighting glass (Fig. 2). By applying a low-reflection coating on the outer surface of the side glazing glass, the direct sunlight L1 that reflects the light to the outside of the building is suppressed, and the light is taken in. Further, since the light-emitting coating is applied to the back surface of the side surface lighting glass 13 in the west, it is possible to prevent the light taken in the light guiding means from transmitting to the outside L2 (FIG. 2).

Also, at the end of the sun before the end of the sun sinking in the West, The side lighting glass 13 placed in the west position is incident on the direct sunlight S2, and most of the light passing through the side lighting glass is taken into the light guiding mechanism (Fig. 2).

Incidentally, due to the daytime time when the sun is in the south, Since the front surface of the above-mentioned sky surface lighting glass 11 is obliquely incident, direct sunlight is incident, so that most of the sunlight can be taken in the light guiding means.

[Second Embodiment]

It is not necessary to distinguish the aforementioned flanged cylinder first light guide 33A or before When the flanged cylinder second light guide 33B is attached, the flanged cylindrical light guide 33 is collectively attached, and the following description will be made.

The aforementioned flanged cylindrical light guide body 33 can be connected to the cylindrical light guide body 32 The light guiding mechanism 30 is configured to be connected anywhere. Further, the flanged light guide body is also the same as the cylindrical light guide body, and the inner peripheral surface is mirror-finished.

The inner circumference of the flanged cylindrical light guide 33 is set to: The elliptical cut surface of the cylindrical light guide 32 when the cylindrical light guide 32 is cut obliquely has the same inner circumference of the ellipse. This is considered to be also connected to the aforementioned cylindrical light guide.

Moreover, the original light guiding mechanism (constituted only by the cylindrical light guide body) does not If it is necessary to bend, it is not necessary to attach the flanged cylindrical light guide 33, but this is not the case in most cases. Therefore, the linear cylindrical light guide 32 is cut obliquely to connect between the cut surfaces, but the cut surface of the cylindrical light guide that is cut obliquely is elliptical, so that light does not leak. And the work that was previously connected in any direction is cumbersome and difficult.

The light guide is constructed by including the flanged cylindrical light guide body The structure is such that the cylindrical (circular) flanges are connected to each other, so that the connection can be freely performed in any direction of 360 degrees, and the construction of the light guiding mechanism becomes extremely easy. Moreover, even if the connection is made in any direction, leakage of light can be prevented, and attenuation of light in the light guiding means can be suppressed, so that it can be utilized for the brightness of the room. Keep it above a certain level.
