Definitions
- the invention relates to a Lichtlenksy stem according to the preamble of claim 1.
- passive light steering systems In the course of the increased use of solar energy for coping with the energy problems, passive light steering systems have become increasingly important. With such passive systems, for. B. controls the sunlight so that it is transmitted in winter and reflected in summer. As a result, active heating elements in winter and active cooling elements in summer can be dispensed with or can be greatly reduced.
- a device for room lighting with daylight and artificial light in which a first reflector casts daylight and the second reflector artificial light onto the ceiling of a room, so that indirect lighting results in both cases (DE -B-631 798).
- the disadvantage here is that the first reflector projects outward like an extended window potion, while the second reflector is attached to a ceiling in the manner of an upward-reflecting umbrella
- a transparent protective roof made of prism glass is arranged above the shop window, which is opposed by an inclined mirror (DE-B-517 827). The light falling through the canopy is directed to the exhibits in the shop window.
- the mirror reflects both artificial and natural light, the entire lighting device is very complex because it requires an informal canopy
- a method for light distribution in a closed room with at least one window facade is known as a space limitation, in which the window of the window facade is divided horizontally into two unequal parts, and is divided into a translucent upper window and a transparent viewing window (DE -A-37 29 553).
- the light is guided through the upper window approximately horizontally or slightly directed against a reflective ceiling surface, while the light flowing in through the viewing window is deflected upward against the reflective ceiling surface behind this window.
- a disadvantage of this known method is the division into two window parts because this division requires horizontally aligned and projecting beams and slats
- a light collector is provided on the outside of the building in front of the light channel and a band-shaped light distribution device adjoining the light channel for veitdiening and guiding the daylight into the interior of the room.
- This light-emitting device can additionally be provided with an artificial light strip.
- a disadvantage of this device is that the space is reduced by the suspended ceiling and an externally projecting light collector is required.
- the same disadvantage also applies to another known device for illuminating interior space, in which a transparent ceiling is suspended under the building ceiling is (DE-A-3523523).
- both rays generated in the room as well as rays radiated through the window and deflected by reflectors in the direction of the ceiling in the area of the ceiling are pyramids with a triangular base and alternately raised and deepened next to each other Pointed reflectors are mainly deflected backwards into the depth of the room and sideways into the room width.
- the disadvantage here is that the ceiling of the room has to be masked out with prism-like structures.
- optical means are used which are suitable for directing incident light from the ze ⁇ nit towards the workstation by deflection (CH-A-194 867).
- These optical means consist of two reflectors arranged one above the other, with the lower one catching the zenith light and deflecting it towards the upper reflector, which throws it into the work area at the required angle.
- This device is not for directing artificial light that is generated in the room itself suitable
- a device for increasing the lighting with natural light in which a series of completely or partially reflecting blinds or slats are arranged in such a way that they reflect the natural light downwards from their underside (DE-A-34 21 063).
- this device is not suitable for reflecting artificial light into a room in a predetermined manner.
- the object of the invention is to create a light-guiding device which simultaneously directs both daylight and artificial light in such a way that indirect lighting always results This object is achieved in accordance with the features of patent claim 1
- the advantage achieved by the invention is in particular that uniform and indirect illumination of a room is possible both during the day and in the evening and at night without having to use bulky light deflection systems.
- Figure 1 is a perspective view of an interior that has a light-emitting device according to the invention in the upper region of a window wall; 2 shows a section through a roof space with a slightly inclined glass roof, which has a light deflection device according to the invention; 3 shows a section through a roof space with a steeply sloping glass roof, which has a light deflection device according to the invention;
- FIG. 4 shows a section through a light deflecting device according to the invention with several reflector profiles for deflecting artificial light
- 5 shows a section through a light deflection device according to the invention with a special reflector for the artificial light source
- 6 shows a section through a window frame frame construction with an artificial light source
- Fig. 7 shows a cross section through an artificial light source with two fluorescent tubes.
- FIG. 1 shows a section through the interior 1 with a ceiling 2, two first side walls 3, 4 and two second side walls, of which only one side wall 5 is visible and with a floor 6 in the upper region the side wall 4 there is an inventive light-guiding system 7 which has a plurality of reflectors 8 to 13 which are arranged parallel to one another and one above the other and within double glazing with the roofs 14, 15.
- an artificial lighting 16 which has a curved reflector 17 and a linear light source, for.
- B. contains a fluorescent lamp 18
- the reflector 17 is white or reflective on its top. For example, it is made of aluminum with a shiny metallic surface or a comparable material.
- the light from the fluorescent lamp 18 reaches reflector surfaces 19 to 23 of the reflectors 8 to 13 on the room side and is reflected back from there into the room 1, which is indicated by the light beams 24, 25, 26.
- the light 28 coming from the sun 27 is also emitted by the Deflected light control system 7, depending on the angle of incidence either on the ceiling 2 or back out.
- the function of the light steering system 7 is thus, for. B. to shade a window workplace and the light - regardless of whether artificial or daylight - to the ceiling 2 or in the depth of the room. Due to the double function of the light-steering system 7, constant lighting can also be produced. For this purpose, only the artificial light source 18 needs to be controlled depending on the outside brightness. As daylight becomes stronger or weaker, artificial light can become weaker or stronger. Instead of regulating a single tube, which is simple in the case of filament tubes, but difficult in the case of fluorescent lamps, it is also possible to switch on several tubes in steps. Regardless of the daylight intensity, the daylight state can thus be maintained without having to immediately switch to a nighttime situation which uses more energy than is actually necessary for illumination during the day.
- the daylight-dependent regulation can be carried out manually. However, it makes sense to use a photocell 29 which, for. B. is arranged in the interior at the deepest point
- An essential feature of the invention consists in the close spatial-optical connection between the artificial lighting 16 and the window zone with the light directing system 7.
- window surfaces viewed from the interior, are regarded as black surfaces, ie they are considered to be Reflectors are practically ineffective because the light striking them is lost to the outside.
- the window surface is illuminated from below with artificial light. The illumination takes place at the smallest possible angle, so that no artificial light penetrates outside
- FIG. 2 shows a vertical section through the roof space 30, of which three walls 31, 32, 33 and a light guiding system 34 can be seen as a sloping roof.
- the light guide system 34 is in turn installed between two panes 35, 36 and contains a plurality of reflectors 37 to 51, which are designed as reflector profiles with at least one outwardly directed reflector surface 52 and one inwardly directed reflector surface 53.
- an artificial lighting 54 is arranged below the light steering system 34, at a distance of at most one meter, which consists of a lamp 55 and a reflector 56 in the manner of a reflection screen.
- the artificial lighting 54 radiates again from below or obliquely onto the lighting steering system 34.
- FIG. 3 shows a section through an interior 57 in which a lighting system 58 is constructed in such a way that it is transparent to the high sky rays 59, 60.
- the artificial lighting 61 is installed at the top; H.
- the artificial light is radiated obliquely from above onto the light steering system 58 and from there is reflected into the interior 57, which is indicated by the light rays 62 to 64.
- the oblique action of the light steering system 58 thus takes place from a direction from which the sky or the exterior are not visible.
- the lighting systems in the figures always consist of individual reflective profiles. These are completely or partially mirrored, depending on whether diffuse light scattering or exact light deflection takes place.
- the reflector parts directly impacted by the sun 27 are expediently designed to be reflective, in order to be able to exercise exact control over the passage of light, while the reflector parts 53 impacted by the artificial light z.
- B. can be white reflective, whereby a diffuse light distribution to the interior is achieved.
- prisms could also be provided in the light steering system, but at least the prism side exposed to the artificial light must be designed to be reflective. Prism rods or prism plates could preferably serve as prisms.
- a prismatic plate consists of a translucent plate that has prismatic shapes on at least one south Under certain circumstances, it is unavoidable that small amounts of artificial light escape to the outside, since the angle of the artificial light exposure from the inside changes with the distance of the individual reflectors of the light steering system from the artificial light source. However, it is sufficient if the largest part of the artificial light is in the interior is reflected back.
- This light steering system 65 again consists of several reflectors 68 to 78, which essentially consist of three reflector lanes 79, 80, 81.
- the reflector part 79 is parabolically curved and extends from the inner wall of the glass bowl 66 to the inner wall of the glass bowl 67.
- the reflector part 80 adjoins one end of the reflector part 79 and is approximately half the size of the reflector reflector part 79. It runs at an angle of approximately 25 degrees downwards and is connected at its end to the third reflector door 81, which is perpendicular to the reflector part 79.
- a fluorescent tube 82 which is flanked on both sides by a respective reflector 83, 84, which is as flared as the reflectors 68 to 78.
- a respective reflector 83, 84 which is as flared as the reflectors 68 to 78.
- reflector 84 To the right of that Reflector 84 and approximately at the same height there are two further reflectors 85, 86, which are constructed in the same way.
- the lamp 82 is an arbitrary emitter such.
- the spotlight can consist of a large number of individual light sources or, in the case of a neon tube, also of an elongated spotlight. It would also be conceivable to arrange several light sources side by side or one above the other.
- the reflectors 83 to 86 have at least one reflecting surface 87 to 90, which is in optical connection with the lamp 82.
- the reflecting surfaces 87 to 90 are positioned such that the light of the lamp 82 striking them is either directed onto the light steering system 65 and / or is reflected or reflected on a ceiling 91.
- the reflectors 83 to 86 have a thin profile shape and also serve to deflect certain rays 92 through the reflector system 65 onto the ground level.
- the reflector door 79 of the light steering system 65 are mirrors which do not reflect low-level sun radiation 93 into the interior and high-level sun radiation 94 into the interior.
- the reflector parts 80 are also mirrored, but aligned with the interior so that they reflect the rays 95 to 100 coming from the lamp 82 back into the interior.
- the reflected rays 101 to 103, 92, 104 can strike the ceiling or the floor level in the interior, for example.
- the reflectors 68 to 78 of the light steering system 65 are all shown identically in terms of their shape and orientation in FIG. 4. However, it would also be quite conceivable to shape the reflectors differently and / or to orient them differently in order to achieve further lighting effects.
- the light radiation 105 penetrating through the light-guiding system 65 is collected by a reflector 84 of the artificial light 106 and redirected to the light-guiding system 65 or to the ceiling 91.
- the advantage of this construction is that the light radiation does not penetrate to the work place and thus also no disturbing glare effects can cause.
- the optical coupling of the lighting system 65 with the reflectors 83 to 86 of the artificial lighting 106 allows the reflectors 68 to 78 of the lighting system to be arranged at a greater distance from one another in order to have a better view outside, but without having to accept undesired glare effects.
- the reflectors 83 to 86 of the artificial light 106 thus become part of the light control system 65. It is therefore also important that the reflectors 83 to 86 may be extended beyond the lamp 82 and lie in front of the light control system 65 as a band to be able to perform this double function.
- FIG. 5 shows a device according to the invention, in which a light steering system 107 serves as a skylight window zone.
- the light steering system 107 in turn has a number of reflectors 108 to 112, which are located between two glass panes 113, 114.
- the entire system 107 is fitted into a window frame 115, 116 which abuts a stop 117.
- An artificial light source 218 is flanged to the frame 116 and consists of a reflector 119 and a lamp 120.
- a conventional insulating glazing 121 is provided below the stop 117.
- the reflector 119 which is part of the light 123, 124 directs the lamp 120 onto the light-guiding system 107.
- the light is therefore deliberately blasted into the daylight-emitting opening - a process that is usually avoided as far as possible.
- Another part 125, 126 of the light is radiated directly into the interior in the direction of the ceiling 118
- the artificial light source 218 is shown in more detail with a window frame 129.
- a window wing 130 with a conventional insulating glazing 131 abuts on the window frame 129 and a window wing 132 on the upper side, which carries the light system 107.
- the artificial light source 218 is flanged onto a projection 133 of the window frame 129 by means of the box 134.
- the reflector 119 of the artificial light source 218 is placed as an involute / involute 135 around the lamp 120 and then extends to a point 136 first reflector fitting 137 is extended by a second reflector fitting 138, which is flat.
- This fitting 138 could, depending on requirements, also be designed in the form of a circular arc or parabolic. Due to the formation of the first piece of tea as an involute or involute, the light 139, 140 of the lamp 120 is radiated to the window, while the floor level is shaded.
- a ballast 141 for controlling the lamp 120 is also accommodated in the box 134, insofar as it is a fluorescent lamp
- FIG. 6 clearly shows the advantages of the reflection system according to the invention.
- the plastic light source 218 can be made so flat that it can be screwed onto the projection 133, so that it is possible to open and close the upper and / or lower window sash 132, 130.
- the height of the box 134 is less than 5.5 cm, d. H. the plastic light source 218 can be screwed onto any conventional frame bar construction.
- a portion 142, 143, 144 of the light is radiated directly into the room by the reflector 119
- FIG. 7 A further embodiment of an artificial light source 145 is shown in FIG. 7.
- a twin tube 146, 147 is encased by a reflector fitting 148 which extends from the twin tube 146, 147 to a point 149.
- This reflector portion 148 is not an involute or involute constructed, but still has an invo- luten or involute-like shape.
- a second reflector fitting 150 which extends from point 149 to end point 151, is shaped like a parabola
- the reflector elements are used mathematically as an involute, i.e. H. a projective bending of a cluster of points, straight lines, planes or hyperplanes in itself, or as an evolve, d. H. as a flat curve which is obtained when the tangents are constructed in all points of a given curve and the length of the arc from the point of contact to the certain fixed point of the curve can be designated on them.
- the light steering system according to the invention is not limited to specific dimensions. However, if it is used for conventional living or office rooms, its dimensions are determined by the usual room size. In this case it is advantageous to place the artificial light source at a distance of less than 0.5 m from the window area (Fig. 1) or less than 1 m in the roof area (Fig. 2, Fig. 3).
- the light-reflecting elements are always shown as rigidly arranged profiles which form a solid structural unit with two glass panes.
- this embodiment is particularly advantageous - cf. for example the production of such profiles according to German patent application P 40 01 471.1 - the invention is nevertheless not restricted to this. Rather, controllable lamellae are also detected, the relative angular control of which, for. B. can be changed by Seüyak or the like. It is only important here that the lamellae can be brought into such an angular position that they reflect the illuminating artifacts into the room without simultaneously blocking the daylight.
- the light-reflecting elements it is also not absolutely necessary for the light-reflecting elements to be arranged in a vertical axis which runs parallel to two flat glass panes. Rather, it would also be possible to have the axis of the light-reflecting elements run at an angle to the flat glass panes. In this case, the individual elements would be arranged one above the other like roof tiles, however, in contrast to the conventional roof tiles, an intermediate space between the elements would be provided, which Allow natural outside light to pass through. Due to the lateral offset in the parallel plane, each element would have a dome above the element underneath. This dome could radiate artificial light shining vertically from the bottom upwards into the interior, ie it would be possible to Kunsüichtqudle itself to be built into the space built through the two glass panes.
