Definitions
- the invention relates to a daylight lighting device with at least one to the side of the light concave curved reflective slat.
- Such daylight lighting devices are as Known blinds. It is also known to be one Venetian blind in the pane of an insulating glass window to accommodate.
- the reflective slats cause the incoming light to be redirected lead them diagonally upwards into the building. Depending on the height of the sun, the slats can be adjusted so that their angle of inclination changes becomes.
- such blinds take into account not the changing azimuth angle of the sun during of the course of the day.
- DE 44 42 228 C1 discloses a daylight lighting device known from a lamellar design Plate consists of light-conducting material.
- the edge of the plate that faces the incident light has a beam-focusing curve. Thereby the incident radiation inside the Plate is focused and the emerging radiation is bundled or directed.
- the one on the opposite side The face of the plate is wavy Profiling on to direct the light in azimuthal Direction to improve.
- Such a light-guiding Panel structure points in the interior of a window room a significant mass due to absorption heat up and thereby the heat load of the building can increase.
- the invention has for its object a daylight lighting device to create that with simple Average homogeneous room lighting enables azimuth angles at which the sun does not shine perpendicular to the facade.
- the slats are made of thin sheet metal if necessary with a base layer can be, but otherwise only a small thermal Has mass. Light shining on the slat falls, is scattered diagonally upwards, with one Scattering occurs in the azimuth range. The incoming sunlight so it’s not going straight into the room steered into it, but it gets horizontal Diffuse level.
- the lamella is preferably about its longitudinal axis Side of the incidence of light curved concavely. This will achieved that the incident light also in the vertical Level is diffusely scattered.
- the lighting device can be in a facade element, e.g. a window, but it can also like a lightshelf in its own elongated Housing body to be housed, the one Facade is placed.
- the daylight lighting device is particularly installed in skylights. Under a skylight is understood a window or facade area, which is located above the head or eye level is, usually over a viewing window. The Daylight lighting device is then used in the skylight incident solar radiation on the To direct the ceiling area of the room.
- the device shown in Fig. 1 has between two glass panes 10 and 11 form an arrangement a plurality of slats 12 arranged one above the other.
- Each lamella 12 consists of an elongated one Sheet metal strip that is concavely curved, with the hollow side directed upwards and thus facing the sun is.
- incident sunlight 13 according to FIG 1 from the reflective hollow side of the lamella 12 reflected one or more times, the emerging Light 14 is emitted as stray light.
- the lamella 12 is, as in FIGS. 2 and 3 is provided with transverse shafts 15.
- This Waves extend across the entire slat width.
- the waves are 15 sinusoidal. In any case, it is about rounded waves.
- the length of a shaft 15 is smaller than the width of the slat. Through the transverse Waves 15 will scatter light even in azimuthal (horizontal) plane caused, so that luminance concentrations in the room to be illuminated be avoided.
- the slats 12 are arranged in the skylight area, So above the eye level of people. At an angle from above incident sunlight becomes oblique under scatter directed upwards into the room to be illuminated, where the Ceiling area is evenly brightened. This brightening takes place regardless of the daily course of the sun in the azimuthal direction.
- the one under the slat area located window area can be see-through or also be opaque.
- a conventional shading device consisting of slats 23 arranged and another consisting of slats Shading device 24 is located in front of the Viewing window 21.
- This lighting device 25 is provided, which is arranged under the projection 20 so that it is illuminated by the sun.
- This lighting device 25 has an elongated bar-shaped Housing body 26, which has an oval cross section here.
- the bottom wall 27 is with a longitudinal slat 12 covered, the width of which is almost as large as that Width of the case body.
- This lamella 12 is corresponding the shape of the housing is concave and it is additionally provided with transverse shafts 15, such as the slats of the first embodiment.
- the top wall of the housing body 26 is a light entry window 28 and a light exit window 29 are provided and between the two is an opaque one Shading 30.
- the interior of the housing body 26 is sealed against the environment so that no dust can penetrate.
- Light coming through the light entry window 28 occurs is scattered by the lamella 12 and comes out of the light exit window 29 at an angle directed above diffuse. This way it will Skylight 22 supplied with light. Because that Light entry window 28 and the light exit window 29 are convexly curved is a self-cleaning effect given to some extent.
- guer running waves An advantage of the guer running waves is that the slat has an azimuth detection range of approximately Has 180 °. This means that with a north-south orientation the slat almost all day, while the sun moves from east to west, light in the depth of the space behind the slat is sent. Brightening and glare effects effective and avoided with simple means. Furthermore light can be introduced into the building without excessive heating occurs.
