The lighting unit of the present invention is installed in an office, a factory, a house, or the like, and is implemented as an illumination facility in an arbitrary space inside the building.

(Example 1)

First, the configuration of the lighting unit of the first embodiment will be described with reference to Fig.

The mining unit (1) comprises a mining projecting body (10) projecting upward from the roof surface, an irradiation mechanism (20) for emitting the light received from the mining projecting body to an arbitrary space inside the building, A light guide mechanism 30 for connecting the light source unit and the irradiation mechanism while suppressing the decline of light, and a ventilation mechanism 40 for suppressing the temperature rise inside the light unit (FIG. 1).

The mining projecting body 10 includes a top surface and a rectangular top surface mining glass 11 disposed on the top surface and inclined at an angle of 45 degrees with respect to the mounting base, A side surface 12 of the protruding body that cuts a part of the side surface of the protruding body, and a side lighting glass 13 that cuts a part of the side surface of the protruding body (FIG. 1).

The angle of inclination of the surface-side mining glass 11 is inclined at an angle of 45 degrees with respect to the installation pedestal, but it can be arbitrarily changed if the brightness of the arbitrary space inside the building can be maintained within a certain level. It is assumed that it is possible to maintain the brightness of the arbitrary space inside the building at a certain level or more if the brightness is within the range of 30 degrees to 60 degrees.

Although the shape of the above-mentioned topsheet mining glass 11 is rectangular in consideration of the processing cost of the glass, it is also acceptable to change it to a circular shape if necessary.

In addition, the size of the above-mentioned surface-side mining glass 11 can receive more sunlight than a larger size, but is preferably at least larger than the diameter of the light guide mechanism 30.

Since the side lighting glass 13 is installed in order to mainly receive the low-altitude solar light at the early morning or at the sunset when it is difficult to receive or receive only a small amount of light in the above-mentioned topslight glass 11, When the above-mentioned mining projecting body 10, which is capable of receiving most of the direct sun beams from the east azimuth in which the sun of the sun exists, and the west azimuth in which the sun exists at the sunset, It is required to be provided at the side surface 12 which is the eastward and westward directions.

In the present embodiment, a side window glass 13 such as a window having a trapezoidal shape is provided in a certain area on both sides of the light projecting body 10. However, if the brightness of an arbitrary space inside the building is within a range , It can be designed and changed in other ways. For example, it is also possible to allow a side surface minuter to be provided on the entire surface area, all the side surfaces, or the entire circumferential surface of both side surfaces.

Although a low-reflection coating for suppressing the reflection of light is applied by applying a low-reflection coating to the outer surface (outer surface of the building) of the side lighting glass 13, if the same operation and effect are generated, Reflective coating may be applied to the surface of the substrate (not shown).

Although the light reflection coating is applied to the inner side of the inner side of the side lighting glass 13 to reflect light from one direction but to reflect or block the light from the other direction by applying a light reflection coating, It may be carried out by applying a light reflection coating to the outer surface.

Instead of applying the low-reflection coating and applying the light reflection coating, it is also possible to use a sheet-like material and a material which generate the same action effect as the low reflection processing and the light reflection processing (Material or material that reflects or blocks light) is adhered to one side of the side glass, so that low-reflection processing and light reflection processing can be performed.

Although a flat and transparent net glass is used for the side lighting glass 13, it can be changed into another glass if the brightness of an arbitrary space inside the building can be maintained at a certain level or more. In addition, we can accept design change with materials other than glass.

It is preferable that the irradiation mechanism 20 be provided with a function of suppressing the focus of light at the lower side of the light guide mechanism and irradiating homogeneous light so as to keep the brightness of the arbitrary space inside the building at a predetermined level or higher And more preferably an illuminance adjusting mechanism for adjusting the position or amount of reflected light reaching the ceiling face cover.

The light guiding mechanism 30 is a cylindrical light guiding body 32 of a cylindrical shape without a seam whose inner circumferential surface is mirror-finished and in which the distal end portion 31 is inclined at an angle of 45 degrees with respect to a mounting base, (See Fig. 1).

In order to receive more sunlight with respect to the inclination angle of the front end portion 31 of the cylindrical light conductor, the angle is set at 45 degrees with respect to the installation pedestal like the above-mentioned surface-side mining glass 11. However, Is within a range in which the brightness of the light source can be maintained at a predetermined level or higher.

The cylindrical light pipe 32 may be a cylinder formed by mirror-finishing one side of the flexible plate member and joining both end portions without gap to each other.

Of the constitution of the cylindrical light conductor 32, a part for receiving sunlight from the side lightening glass 13 is of course machined such as cutting so as not to block the incidence of light.

The ventilation mechanism 40 is equipped with an outer periphery of the light guide mechanism (a position which becomes a northward orientation when the light projection body is provided) so that ventilation air flows through the narrow- (Inside the building) to the roof (outside the building), thereby suppressing the temperature rise inside the lighting unit. In addition, a non-return damper is provided to prevent the air from entering the room from the roof due to a storm or the like (Fig. 1).

Next, a description will be given with reference to Fig. 2 with respect to a state in which sunlight at an early morning, sunset, and lunch is received from a projecting body for mining, with the right side being the east side, the front side being the south side, and the left side being the emotion side.

In the early morning when the sun began to rise in the east bearing, a direct sun beam S1 was incident from the side lighting glass 13 installed on the side of the east bearing of the light projecting body (FIG. 2).

Most of the direct sunlight S1 reaching the side lighting glass 13 installed on the side of the east bearing passes through the side lighting glass and is received by the light guide mechanism (Fig. 2). By applying a low-reflection coating to the outer surface of the side glass-mining glass, the direct sunlight L1 which reflects and blasts out of the building is suppressed, and the light-blowing is promoted. In addition, since the light reflection coating is applied to the inner side surface of the side lightening glass 13 in the west orientation, the light L2 received by the light guide mechanism is blocked out (FIG. 2).

The direct sunlight S2 is incident from the side lighting glass 13 installed at the westward azimuth of the sun before the sun is set to the west direction and most of the direct sunlight S2 is transmitted through the side lighting glass and is received by the light guide mechanism (Fig. 2).

In addition, since the direct sunlight falls from the front of the slope-mounted mining glass 11 at the time of the lunch where the sun is located in the south bearing, much sunlight is received by the light guide mechanism.

(Example 2)

The second embodiment differs from the first embodiment only in the light-guiding mechanism in that the structure of the light-guiding mechanism is different from that of the first embodiment, with reference to Figs. 3 to 6 only.

The light guiding mechanism 30 has a cylindrical first light guide 33A having a flange at an angle of 15 degrees at only one end or a cylindrical second light guide 33B having flanges with both ends inclined at 15 degrees ) (Figs. 3 to 6).

When it is not necessary to distinguish between the flange-attached cylindrical first light guide 33A and the flange-attached cylindrical second light guide 33B, the flange-attached cylindrical light guide 33 is used .

It is assumed that the flange-attached cylindrical light conductor 33 is connected to the cylindrical light conductor 32 at a certain position so as to constitute the light guide mechanism 30. Also, with respect to the light guide with the flange, the inner circumferential surface is mirror-finished similarly to the cylindrical light guide.

Is equal to the inner circumferential length of the ellipse of the elliptical cut surface when the cylindrical light conductor 32 is obliquely cut with respect to the inner circumferential length of the cylindrical light conductor 33 with the flange. This is also considered in connection with the cylindrical light pipe.

In addition, if the light guide mechanism (constituted only by the cylindrical light guide body) that does not require bending at the beginning is sufficient, the cylindrical light guide body 33 to which the flange is attached is unnecessary, but in many cases it is not. Therefore, although the straight cylindrical light guide 32 is cut obliquely to connect the cut surfaces, the cut surface of the obliquely cut cylindrical light guide is elliptical, so that the light is not leaked and is connected in any direction The work was annoying and also difficult.

(Circular) flanges are connected to each other by configuring the light guide mechanism including the cylindrical light conductor with the flange, so that the light guide mechanism can be freely connected in any direction at 360 degrees, . In addition, even if connection is made in any direction, light leakage can be prevented, and the decline of light in the light guide mechanism can be suppressed, so that the brightness of the room can be used to maintain the brightness at a certain level or higher.
