Definitions

  • the invention relates to light directing louvers according to the preamble of the main claim.
  • the functional section with light control of the interior is a concave curved mirror with the disadvantage that in order to achieve the desired anti-glare, steep light deflection inwards, a very large louver height h is required, which allows a reduced viewing of about 70% between the louvers.
  • the ladder cord steps do not lie in the folds, in a form-fitting manner. Forming of a small pack of louvers comprising blinds that have been moved close together is prevented with disadvantages.
  • Fig. 1 1 and Fig. 13 also have a reflector section 120 with a flat daylight redirecting contraption into interior. Redirect the daylight does not take place, however, for Zenith radiation.
  • the disadvantage of the flat daylight redirecting contraption is the glare in the interior due to the flat daylight redirecting contraption of the central flat section. This can occur directly in the eye of the viewer. The louver can, therefore, be used at al all events in the upper area above the eyelevel. Another disadvantage is the requirement of 2 types of louvers in one blind.
  • Figs. 36 to 38 show surface folds in the first part oriented for sunshine, whose folded sides that direct the daylight have an angle of 10° to the horizontal, so that the collected zenith radiation is deflected only to the underside of the upper louver, without illuminating the interior space in depth.
  • the mutually perpendicular folded sides in the first section prevent a light deflection of flat sun in the interior, so that with these louvers that have been developed primarily for sun and light protection, lighting the room with deflected zenith light / sun is not possible.
  • DE 198 285 42 A1 a light-guiding section 97 was specified for the light-deflecting section 91 in Fig. 1 1.
  • the possibility of zenith-light directing - as is desirable, especially for large buildings depths, to save artificial lighting is, however, extremely limited due to the folded structure.
  • the high sun (see Fig. 1 .0) incident on the functional part to redirect the daylight inwards is only minimal, but directed essentially outside. Only a few inward deflected light rays actually fall between the louvers into an interior. A large part applies only to the underside of the upper louver; maximum share is retro- reflected adversely toward the sun incidence.
  • the daylight-directing folded sides have an inclination angle of about 30°, but the angled daylight-deflecting folded sides are so large that only a minimal share of zenith radiation can be deflected inside.
  • the innovation has therefore set itself the task of developing a zenith daylight-directing louver, which is disposed in the skylight of a blind or window and deflects most of the zenith radiation with incidence angles between 40° and 80° in flat angles into the room and shows a deflection for high solar radiation in the lower region of the blinds hanging.
  • the aim is to optimize the following daylight-directing functions:
  • the inclination of the daylight-directing folded sides b 4 in daylight directing section 1 1 , 41 at an angle ⁇ gradually increases from the louver-middle to the louver edge 20.
  • the daylight-directing folded sides b 4 in the first lamellar section are at least configured, partially twice as wide as the angled folded sides.
  • the light-receiving folded sides bi / b 2 in daylight-deflecting louver section 10, 40 are disposed at angles a and ⁇ . a amounts to about 40° to 60°, increasingly from the louver centre to louver edge and ⁇ amounts to approximately 30° to 60°, increasingly towards the louver centre.
  • the folds are configured at angles ⁇ circa 80° to 100° and in the section directing the daylight inward ⁇ > 100° to 160°.
  • the angle will vary depending on the louver spacing and inclination angle of the shadow line S and are, therefore, to be understood as exemplary.
  • Essential to the invention is the functionality.
  • the design features of the main claim ensure the desired physical and photometric characteristics of the light guiding blinds.
  • the features can be represented at least for cross-section parts of the louvers as follows:
  • ⁇ b 4 / ⁇ b 3 > ⁇ bi / ⁇ b 2 as well as ⁇ b 4 / ⁇ b 3 > ⁇ b 2 / ⁇ bi
  • the opening width W is at least partially three times as large as W in the second section. Due to the larger opening widths W 14 , W 15 , W 16 in the section directing the daylight inward against the smaller opening widths W-i to W 13 , W 35 , W 36 in daylight deflecting section and indeed in combination with at least partially larger folded sides b 4 directing the daylight inward, the essential characteristics of the louver contour are defined.
  • a concave shape of folded sides b 4 directing the daylight inward provides a precise light guide.
  • Essential for redirecting the daylight of zenith radiation of > 50% at a shadow line S of 30° is the opening angle ⁇ in the first section. This is > 90°, preferably > 130°.
  • the angles ⁇ of the folded sides directing the daylight inward are formed between 0° and ⁇ 30° - 45°, close to the middle axis 29 in the first section directing the daylight inward.
  • the exact angle at the end point 20 results from the angle of the shadow line S.
  • a tangent incline of 30° results in and for a shadow line S of 45°, there is a tangent incline of 45°.
  • the steeper the shadow line S, the steeper is the tangent angle in louvers endpoint.
  • the lighting requirements in 1 are to be met by the 1 st section that directs daylight inwards with a contour of daylight directing surfaces 1 1.1 .2, 1 1.2.2, 1 1.3.2 ascending towards the louver edges 20, which in angle ⁇ are characterized by the secant 21 , 22, 23, 33, 36 (see also Fig. 9.1 ).
  • the angles ⁇ to ⁇ 3 are configured for louver edge rising upward.
  • the folded sides 1 1 .1.2, 1 1.2.2, 1 1.3.2 are formed concave. Secants 21 , 22, 23 through these folded sides meet in a zone T. T is shown in Fig. 8, for example, in the louver edge 20.
  • the concave shape of the light-directing folded sides ensures the said advantage of exact, mono-reflective and anti-glare radiation guide and a nearly uniform scatter to the interior ceiling as shown in Fig. 1.0, 2.0 and 15 and in Fig. 4.1 , 8 and 14, without having to impinge the bottom side of the upper louver (mono-reflectivity) and without having to blend at very flat sun in a lower pane.
  • This is achieved, in which foci Z and BZ are formed between two adjacent louvers, as shown in Fig. 1 .1 , 4.1 , 8, Fig. 13 and 14.
  • the contour of the concave part surfaces 1 1 .1.2, 1 1 .2.2, 1 1 .3.2 is obtained approximately from fragmentation and a spatial displacement of a parabola-like curve as shown in Fig. 8.1.
  • Fig. 1 1 The climate technical requirements to 2nd on the louvers' development for passive cooling are, as shown in Fig. 1 1 , achieved by the special folded in light-deflecting sections 10 by making the sunlit folded sides of individual folds in their angles ⁇ 4 to ⁇ 5 increase from the louver edge towards the louver centre ( ⁇ 4 ⁇ ⁇ 5 ).
  • the angled folded sides decrease from the louver edge towards the louver centre in their angles of attack a 5 to a 4 (a 5 ⁇ a 4 ), in order to reflect the flatter sun back into the sky in zenith light-catcher mounting position - as far as possible mono-reflectively.
  • the angles of inclination of individual folded sides a and ⁇ are ideally determined in Fig.
  • the width variations bi are ⁇ 30%.
  • the opening widths W of each fold W-i to W 13 correspond to a maximum of twice the folded height F h in the present example, Fig. 8. In the section where daylight is directed inwards, the opening width W is partly up to 5 times the fold height F h and more. In Fig. 12, the ratio h/W in daylight deflecting section amounts to 1/1.6, in the section where daylight is directed inwards it is 1/9.
  • a micro folded, adapted to the louvers' width can have a folded height of F h 0.1 to 3.0 mm.
  • the folded height can even be smaller than 800 nm, however, can be made larger than the wavelength of light.
  • louvers in zenith light-catcher installation on the upper area of the curtain and the louvers in the turned louvers installation are fitted only at the bottom of a blind, so that it comes to a balance of protection and supply function within a curtain by means of only a few louvers.
  • the louvers in the upper and lower curtain region are arranged essentially parallel to one another.
  • the dim setting of the closed blind in Fig. 10 is particularly well realized by the louver edge ascending toward louver section 1 1 or by the ascending connecting line 14 between folded peaks 16, 17 in Fig. 8.
  • the inner-side louver edge inclines to the underside of the upper louver and closes the gap between the louvers.
  • the elevator belt 30 can be laid down without obstacle between the closed louvers on the folded peaks. Also in zenith section where daylight is directed inwards in the upper area of the curtain blind in Fig. 9 shows a good sealing.
  • the curtain strung in a ladder-cord fold into a small pack of louvers without having to insert the ladder cord webs into the folds upon moving.
  • a blind threaded in the ladder cords with large folds forms larger louvers' sets, because the ladder cord webs are not joined into the fold in a form-fit manner.
  • the ladder cord webs should be substantially wider than the louvers themselves, which leads to inaccurate positioning of the louvers in the open curtain. This problem is not there any longer due to the miniaturized fold formation at folded height ⁇ 2 mm.

  • Fig. 1 shows a louver of the prior art with the light guide for solar incidence angle of 60°. Only 30% of the incident zenith radiation is deflected into the interior. The incident occurs at angles of 30°, without illuminating the interior throughout the room. There is a lack of horizontal light entry. Approximately 75% of the incident zenith radiation is undesirably reflected back into sky.
  • Fig. 1 .1 shows an embodiment of innovative, asymmetrical flat louver for a solar incidence angle of 60°.
  • the louver shows the improved light guide on the section 1 1 directing the daylight in the interior by 65% and only a minimal light deflection.
  • Sunlight is, according to the object, mono-reflectively redirected by the concave folded sides 1 1.1 , 1 1.2, 1 1 .3 in a scattering angle of 0° to 45° into the room. Thanks to the folded sides rising at the folded edge 1 1.1.2, 1 1.2.2, 1 1 .3.2 and the greater width b 4 as a result of larger opening widths W 14 , W 15 , W 16 in Figs. 8 and 12, the flat steering of daylight is allowed for illuminating the room depth.
  • Fig. 4.1 shows the optical behaviour of the said louver of Fig. 1 .1 at a sunlight incidence angle of 30°, but in a position flipped by 180°.
  • the section 1 1 directing the sunlight is turned inward and the light-deflecting section 10 is turned for guiding the sunlight outward.
  • the light-deflecting section 10 mono-reflectively deflects sun up to a sunlight incidence angle corresponding to the angle of the shadow line S.
  • the section 1 1 directing the sunlight inward steers the flat winter sun mono-reflectively and indeed at angles ⁇ 30° to ensure an anti-glare for the user.
  • louver height h amounts to ⁇ 2 mm in a louver width of 60 mm. It results in a viewing up to 90%, while in the prior art in Figure 1 , the viewing is only 83% - even at steeper inclination of the shadow line of 35°.
  • the curves a' show the light transmission between the louvers and the curves bi/b 2 , the inwardly deflected radiation components for the zenith light-catcher position of the louvers in Fig. 5.0 and Fig. 5.1 , and for the turned louvers position in Fig. 6.0 and Fig. 6.1.
  • Figs. 7 and 7.1 show, in the curves c', an addition of light transmission of the inwardly deflected radiation b-T + b 2 ' from Fig. 5 and Fig. 6 or Fig. 5.1 and 6.1.
  • a comparison of curves c' in Figs. 5 and 5.1 shows the great advantage of the innovation:
  • This also shows a comparison of the shaded area below the curved sections c' in the diagrams of Fig. 7.1 and 7.
  • the new design guidelines give rise to an approximately 3-fold higher incidence of light in a Lambertian radiation range (diffuse sky light).
  • louvers Due to the innovative design of the louvers, it is also possible to redirect the flat sun in winter onto the section directing the daylight inward into the room. This is clear from a comparison of Figs. 6 and 6.1 for the incidence angle up to 15°, marked by dashed line.
  • Fig. 8 shows details of the louver contour development, by means of which the above functions are achieved.
  • the construction of the louver tops takes place according to rules, which cannot be derived from the prior art.
  • the peaks 60, 61 in Fig. 8.1 or 50, 51 in Fig. 13.1 lie on a line at an angle of 0°, unlike the prior art in Fig. 03.1 .
  • the section 1 1 in Fig. 9 has wider folded sides b 4 that direct the sunlight inward.
  • the angled folds b 5 are at least partially narrow, so that ⁇ b 4 > ⁇ b 5 results in.
  • the folded sides bi and b 2 In section 10 with light being directed back in the direction of sunlight incidence, the folded sides bi and b 2 have, as compared to the prior art, approximately the same width and consistently smaller folded angles ⁇ and opening widths W.
  • section 1 1 with daylight directing inward, it results in at least partially folded angle > 130°, wherein the folded sides b 4 are disposed at angles ⁇ to ⁇ 3 turning inward, which increase towards the louver edge. These angles can be between 0° and 45°.
  • the tangent angle at the folded sides b 4 can be near the louvers' centre 29 0° to 5°, and at the lamellar edges 20 to 25°, e.g. 45°, preferably 30°, thus corresponding to the angle of the shadow line.
  • Fig. 18 shows the light deflection of flat sun in reverse mounting position of the louvers with the first section oriented inward.
  • Flat sun in incidence angles ⁇ 10° is deflected antiglare inward at angles > 20°.
  • This is achieved, in which the angled folded sides b 3 provide shades to the very flat inclined sections c with tangent angles ⁇ 5° of the folded sides b4, so that the light bending inward occurs at least at angles > 20°.
  • Fig. 13 shows the flat steering of daylight inward in voluminous spaces and the scattering of light at the concave folded sides that direct the daylight inward for angles of incidence of 50° and 65°. It manages a uniform light scatter, independent of the sun incidence angle, in the interior depth.
  • Fig. 13.1 shows an alternative to the V-shape of the folds in U-shape.

  • Fig. 1 1 shows the ideal structure for the folded angle of the daylight deflecting section of the louver. Deviations from this result in folded peaks and valleys alone by the manufacturing tolerances and fillets. Therefore, the innovation applies primarily to construction guidelines. Production-related deviations such as rounding at the edges are always negligible. Solar radiation in incidence angle greater than the angle of the shadow lines is essentially redirected mono-reflectively in the sky - a particular advantage of the design.
  • a louver of Figs. 9 and 12 can be manufactured in widths of 2.5 cm to 10 cm.
