Lighting component

The present invention relates to a lighting technology Saueleaent with a light drop shaft and an at least partially light-permeable cover element arranged on this.

The use of τοπ skylights for improvement the lighting conditions in rooms with low, The incidence of daylight from the side is a fact that has long been known in structural engineering. Such skylights are preferably installed in the ceilings of large work, living and hall rooms. With a well-known Embodiment consists of the Oberlieht from an ¥ ertikal

• ·

in the ceiling arranged hollow cylinder, whose ins Free protruding end face is covered with a domed glass dome.

A skylight does its job, of course, the better the more it is controlled Daylight there for as large a fraction as possible during the day can fall into the room to be illuminated. But now the sun is moving on our latitude as is well known, between the so-called winter solstice and the summer solstice from a daily high to change. The highest level that can be reached on our latitude in summer (i.e. on June 15, 12 a.m.) is including approx. 66. In the case of an essentially horizontal dome, therefore, the entire Dome surface can be illuminated by the sun. The sun's rays only hit a fraction on the surface of the dome and after being wrung into the vertical position below the dome Tube, depending on the length of the latter, reflected one or more times (see Fig. 1) · - These are widely used today The type of skylight is therefore relatively poor in efficiency.

The skylight forming the subject of the present invention avoids the disadvantages mentioned.

Is is characterized according to the invention in that the plane of incidence of light of the cover element with respect to

• # * ι

a horizontal plane is inclined,

Thanks to the inclination of the cover element is the incident on the same and then into the The amount of light reaching the room is no longer left to chance, as was previously the case ·; both the overall orientation of the Cover element as well as its angle of inclination can can now be selected in such a way that, on the one hand, the illuminance and light distribution required inside the room or light leveling or light concentration is achieved, but that on the other hand also very different optical effectiveness of the structures, squares, lakes, etc. surrounding the building is taken into account.

The lighting conditions acting on a building from outside are not only dependent on unchangeable factors (adjacent buildings, reflecting water surfaces, etc.), but also on the interplay of the position of the sun, the cloud cover and the surface of the earth (snow cover, etc.), which changes with the respective time of day and season. ). In order to also be able to take these constant fluctuations into account, the light incidence shaft is expediently designed to be rotatable. This allows both the total amount of light falling into the interior and its distribution to be controlled at will.

660349

The light entry shaft is expediently designed in the form of a truncated cone or pyramid, however, it is by no means limited to these forms.

"Light shaft" is used in the above Description and in the claims a provided in the roof or in a side wall of a building, ) Understood the light transmission certain component, which on the one hand at will as well as outside as well as within the roof or wall plane, but on the other hand only in the form of a flat, the light incident opening surrounding frame can be executed.

On the accompanying drawing, 15 executive examples of the subject matter of the invention are shown vividly. Show it:

Fig. 2 shows a section through a skylight.

whose light incidence shaft essentially has the shape of an irregular truncated cone, 3 shows a schematic front view

of the skylight according to Fig. 2,

4 shows a further sectional illustration of the Skylight shown in Fig. 2 to illustrate: the occurring angles,

5 and 6 and 6a a further embodiment and

7 shows an application of a lighting construction

element on the roof and on the side wall of one 3-storey building.

The skylight shown in Fig. 2 has a Liehteinfallschacht 1, which approximately

; Shape of an irregular, i.e. not symmetrical Riegelels tumpf it has and protrudes through a schematically indicated, horizontal roof 2. The shaft 1 is designed as a metallic hollow body. The upper opening of the truncated cone opening into the open is inclined to a, left to the horizontal and with a cover element 3, for example a protective glass, covered.

Instead of the protective glass 3, a completely or partially transparent one can of course also be used

1d plastic can be used. The cover element can be either flat or curved inwards or outwards. The use of a flat glass plate offers among other things the advantage that water and snow run off well, which ensures perfect self-cleaning.

The inclination of the inner walls of the shaft 1 now causes a, for example Beam 4 incident at 45 ° is deflected into the room to be illuminated after a one-time partial explosion.

Even the rays arriving horizontally at sunrise or sunset, which when using The cylindrical light incidence tubes that are prevalent today cannot be used at all, are at the Inner shaft wall downwards and thus into the interior of the room ι guided, (see beam 5)

In order to achieve a scattering effect, the inner walls of the light incidence shaft 1 with a Scatter coating 6, for example, be lined with highly polished aluminum foil. The skylight works in this case like a uniform, strong light source.

In Fig. 3 the skylight is seen from the front, i.e. from the midday position of the sun. At the bottom Part of the light incidence shaft 1 can be attached a dust glass 7, which provides an additional protection against the wrestling of dust offers.

Fig. 4 shows the angles to be observed in the construction of a top light. The hint which the Inclination of the cover surface 8 relative to a vertical one, the surface Intersecting straight line 9 indicates at the same time the angle between the horizontal plane and that on the surface

8 vertically incident sunbeam. This angle is preferably set to a mean position of the sun, for example 45 °. The apex angles cc and / 3 are of course unequal if the cone is asymmetrical, whereby the most favorable angle combination can be selected depending on the local conditions, ie the position in relation to adjacent structures, aem degree of latitude, the desired lighting, etc. If, for example, the lunch stand and its adjoining parts of the sky are covered by a tall building, the angles and the overall orientation of the shaft 1 will be chosen differently than in a completely free-standing area. It would also be possible to make the light incidence shaft 1 rotatable with respect to the roof 2, in which case the most favorable orientation in each case can be selected depending on the time of day and the associated position of the sun.

The one from roof 2 down into the room

protruding part of the light incidence canopy Measured as desired or omitted entirely.

In the embodiment shown in FIG. 5, the one used primarily for incidence of light The opening is shown hatched for the sake of clarity.

The tongue-shaped opening 14 in this case is arranged so that there is a correction of the light intensity occurring during the day, in particular that Morning and evening light through the light opening 14 is recorded and directed into the interior of the room, whereas to shield or weaken the intense midday rays a completely or partially opaque plate 15 is provided.

It is obvious that the person skilled in the art will readily recognize any such variants of the concept of the invention without leaving the scope of protection of the invention defined in the claim.

6 shows an embodiment of a lighting component in which the Y-angle was chosen to be relatively steep. V.'ird the cover 3 is now "ri ^ h north orientier :, zz is the room interior constantly jesjhützt of direct 3onnen3instrahlun_., As an incoming at the highest position of the sun Sunbeam 5 can not penetrate through the. '. Ichteinfaiischacht first Such shielding of direct sunlight, which still allows the passage of a maximum amount of indirect light

is guaranteed, for example, for hospitals, museums, Workshops for the treatment of light-sensitive products, artist studios etc. of great importance. Here, too, the lighting conditions can be varied as desired by rotating the shaft.

One possible application of the above-described lighting component is illustrated in FIG. 7. Here, both on the roof 10 and on the side wall 11, one is designated in its entirety by "L" Building several aer described lighting elements 13 attached. The overall orientation and inclination the cover elements can be selected so that both the constant factors (adjacent building walls, trees, highly reflective surfaces etc.) as well as the drawbar Appearances (position of the sun, cloud cover, snow cover etc.) are given due consideration.

The level to be achieved within the building

The lighting effect can also be influenced by the shape of the cover element general circular or oval shapes are preferred, all possible for special purposes Shapes such as heart shape, lemniscate shape, polygonal cross-sections, etc. come into question.

Through a combination of the mentioned design features, i.e. the inclination and shape of the Cover element, the rotatability of the light entry shaft and the attachment of a reflective coating can be Control the lighting conditions prevailing in a seam to a previously unknown extent. A steady one Leveling the light without any contrast effect can be achieved in the same way as a concentration of directly incident light rays on very specific parts of the tree.

The shaft 1 can, for example, be a hollow body similar to a truncated cone or a truncated pyramid be executed. Of course there are also any other symmetrical or asymmetrical ones Shapes such as tetrahedra, hollow bodies bounded by Eaum curves, etc. are in question.

An artificial light source can be installed at any point within the shaft 1, whose maintenance could be done very easily from the roof through the upper eye opening.

The light incidence shaft can be made of "any suitable material. In particular Manufacture from metal and / or plastic can be used, depending on the material chosen Certain lighting functions, reflection, scattering, etc. can also be assigned depending on requirements.
