Description
Technical field
The utility model relates to the shutter technical field, relates in particular to a kind of louvre blade that has anti-dazzle, prevents overheated and illumination functions.The utility model also relates to a kind of shutter with above-mentioned louvre blade.
Background technology
Shutter is a kind of window that sunshade, indoor and outdoor are ventilated that can be used for, its have attractive in appearance, protect privacy, block advantage such as ultraviolet ray, be widely used in office, household place.
In the prior art, shutter usually because of importing too much direct sunlight, makes to produce dazzle and indoor overheating near the window place near window, and in office the depths because of the light that imports very little, make in the office dark excessively.In order to reduce light and heat near the window place, the direct projection that just must close shutter, keeps the sun off, so just cause in the office dark excessively, thereby keep the normal operation of office at the day of sunlight employing artificial illumination, to cause a large amount of energy to be wasted like this, and reduce people's comfort and operating efficiency.Therefore, how to prevent near the window place produce dazzle and overheated, and can make indoor depths obtain uniform daylight illumination, be to need the difficult problem that overcomes in the present shutter technical development process.
In general, two parts (generally about shutter can be divided into, the boundary of top and lower part is a benchmark with people's height, described boundary generally is set at 1.9m in the European and American areas, described boundary generally is set at 1.8m in the area, Asia), the top of shutter can be relevant with the lower part, also can be independent two parts that are provided with, the lower part is set to anti-dazzle, prevented heat structure, top is set to the light guiding structure, both can satisfy and prevent to produce dazzle near the window place, overheated requirement can be satisfied the requirement that indoor depths obtains even daylight illumination again.
For the shutter that constitutes by the conventional arched louvre blade, solar irradiation will reflect when being incident upon the upper surface of its louvre blade, the part light of reflection exposes to the bottom surface of the louvre blade that is positioned at the top easily, and the bottom surface of the louvre blade above being positioned at is reflected once more, forms dazzle; When especially solar irradiation is incident upon the inside part of louvre blade, because the angle of reverberation and horizontal plane is certain, the easier bottom surface that is incident upon the louvre blade that is positioned at the top of reverberation, the bottom surface of the louvre blade above being positioned at reflects to form dazzle once more.
At this moment, for prevent sunlight inject indoor, prevent that dazzle from producing, usually need to rotate louvre blade, close the incident that whole blinds sunshade light-conducting system comes block sunlight, and whole blinds sunshade light-conducting system is closed and will be caused indoor needs to open artificial illumination, make daylight illumination to be utilized, the while indoor and outdoor does not have the vision interchange and air flows.
Therefore, how to prevent that sunlight from injecting indoor generation dazzle, and do not influence that the indoor and outdoor vision exchanges and air is mobile, become the technical barrier that those skilled in the art need to be resolved hurrily.
The utility model content
First purpose of the present utility model provides a kind of louvre blade, and this louvre blade need not to rotate and just can prevent that sunlight from injecting indoor generation dazzle, does not influence also simultaneously that the indoor and outdoor vision exchanges and air is mobile.Second purpose of the present utility model provides a kind of shutter with above-mentioned louvre blade.
In order to realize above-mentioned first purpose, the utility model provides a kind of louvre blade, comprises the blade body with a plurality of teeth groove, and to interior side direction, the side to light of each described teeth groove and the angle of horizontal plane increase gradually along this louvre blade outside.
Preferably, described teeth groove is the straight-tooth groove.
Preferably, the angle γ of the line of the tooth end of the tooth end of described teeth groove and inboard adjacent sheaves and horizontal plane

In the concrete scheme, blade body 100 can comprise light-reflecting portion 101, light guide section 102, light-reflecting portion 101 is positioned at the outside of blade body 100, the inboard that light guide section 102 is positioned at blade body 100, a plurality of teeth groove form light-reflecting portion 101, light-reflecting portion 101 is f with the separation of light guide section 102, the width of blade body 100 is L, and the width of light-reflecting portion 101 is L
1, the width of light guide section 102 is L
2, in the preferred scheme, the width L of described light guide section 102
2Probably between 0.4L～0.5L; The upper surface of light-reflecting portion 101, light guide section 102 forms reflective areas and light guide zone respectively, and as shown in Figure 4, the light that is incident upon reflective areas will reflect, and reflexes to outdoorly, and the light that is incident upon light guide zone will deflect and be directed into indoor to the ceiling direction.
In order to import indoor to the ceiling direction light that is incident upon light guide zone, the upper surface of light guide zone can be arranged to arc surface, incident light is incident upon arc surface and will reflects along diagonal upward direction, reverberation is with the directive ceiling, and then import indoor, and the soffit of the louvre blade above can not reflexing to can not produce dazzle.
Can only directive ceiling direction and can not be incident upon the soffit of top louvre blade in order to ensure the light that is incident to light guide zone, the action ratio of light guide zone can rationally be set as required, in the preferred scheme, the action ratio of light guide zone can be arranged between 0～16%.
In the scheme, the action of the light guide zone of the louvre blade of shutter lower part ratio can be 16% particularly, and the action ratio of the light guide zone of the louvre blade on top can be 6.7%.
In the foregoing description; blade body 100 has four teeth groove; the louvre blade that the utility model provides is not limited thereto; the utility model does not limit the quantity of the teeth groove of louvre blade reflective areas; can also have one, two, three or more teeth groove,, allly satisfy along the louvre blade outside to interior side direction as Fig. 4, Fig. 5, Fig. 6 and Fig. 8, Fig. 9, shown in Figure 10; the side to light of each teeth groove and the angle of horizontal plane increase gradually, all should be in protection domain of the present utility model.
By background technology as can be known, shutter can be divided into upper and lower two parts usually, and the light import feature is mainly satisfied on top, and anti-dazzle, anti-overheated function are mainly satisfied in the lower part.For the light directive ceiling direction that is incident upon on the louvre blade of lower part can being improved indoor illuminating effect, the action ratio of the light guide zone of the louvre blade of lower part can be made as higher value, shown in Figure 12 a, Figure 12 b; In order to make the shutter on top can import more rays, the action ratio of the light guide zone of the louvre blade on top can be made as smaller value (0～3.9%), so that can import more rays, and can make that the range of exposures that imports light is darker, shown in Figure 12 c, Figure 12 d.
The utility model also provides a kind of shutter, comprises by a plurality of having certain intervals, a horizontally disposed louvre blade, and described louvre blade is above-mentioned louvre blade.Because above-mentioned louvre blade has above-mentioned technique effect, the shutter with this louvre blade also should possess the corresponding techniques effect, no longer is described in detail at this.
The above only is the description of the preferred implementation of utility model; should be understood that; because the finiteness of literal expression; and objectively have unlimited concrete structure; for those skilled in the art; under the prerequisite that does not break away from the utility model principle, can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
