Definitions

  • the invention relates to a method and a circuit arrangement for adapting the luminous intensity of the total light according to the preamble of claim 1 and according to claim 6.
  • a light-sensitive sensor part is connected to a control part, which in turn controls a dimmer circuit part.
  • the dimmer circuit part controls light sources arranged in the room, which generate a dimmed light level.
  • the light-sensitive sensor part is arranged so that it cannot detect the dimmed light level of the light sources.
  • the light sources are controlled in accordance with a linear, opposing dependence of the dimmed light level on the sensed sensor signal. The inclination of this function, which defines the dependence, is set by a gradient factor.
  • the setting is made at any time of day when the lighting arrangement is started up.
  • Such a method has the disadvantage that not only the dimmed light level present at the time of the adjustment is changed with the setting of the slope of the linear function, but also the dimmed light levels assigned to all other light intensities of the external light are changed.
  • the invention is based on the object of specifying a method and a circuit arrangement in which there are refined setting options for adapting the light intensity in a room.
  • the invention makes use of the consideration that an individual lighting requirement is not met by specifying a single parameter of the function, for example the slope or the parallel displacement, but that this can only be met by specifying the function individually or in sections.
  • Claim 6 is directed to the adaptation of the structural illumination of a room, which can be not only dependent on the outside light intensity but also dependent on the direction of the daylight. According to the invention, the distribution of the light intensity in the room can be adjusted depending on the daylight, so that a certain, if necessary, uneven light distribution can be realized in the room.
  • An observer present in a room perceives the sum of the luminous intensity of the incident external light E ' i and the artificially generated internal light E k as the total luminous intensity of the total light E i .
  • the person present in the room can now, according to the characterizing part of claim 1, on the one hand at any time of the day and on the other hand at any lighting ratio a corresponding light intensity of the interior light and thus the light intensity of the total light. that is, choose the interior brightness without it (the person) being burdened with the actual function of the dependency itself. According to the invention, this function is determined by selecting individual points.
  • the FR 2.174.679 published in 1973, shows a device and a corresponding method with which the percentage reduction in brightness of a room interior lighting is reduced following a function, thereby cutting the function of the outside brightness function.
  • the brightness signals from photocells arranged on the outside wall are linked by a diode network to select the highest brightness level. Independent brightness control with independent dimmers is therefore not possible.
  • FIG. 1 shows an embodiment of the invention with an outside light sensor 1, a dimmer circuit part 3 and light sources 5, 6, 7 that can be connected to this.
  • the dimmer circuit part 3 has a control circuit part 2, a non-volatile read / write memory 8 and a plurality of dimmers 4, only one of which is shown to explain the mode of operation.
  • Several lighting units can be provided in one room, each of which is controlled by the outside light (common outside light sensor) according to a different function.
  • the different functions are stored in the preferably common read-write memory 8.
  • FIG. 2 shows with curve shape a) a linearly falling light intensity of the interior light with increasing light intensity of the exterior light.
  • a person present in the room can adjust a total luminous intensity E i by adjusting the slope or shifting the function a) in E k or E a direction, which is constant, for example.
  • FIGS. 2, 3 and 6 are drawn continuously and continuously, one point-by-point storage and complete definition would require an infinite number of points. If, according to FIG. 5, a desired dependency ratio is now defined by a finite number of values 11, an interpolation to be determined beforehand specifies how the continuous function course controlling the light intensity is generated.
  • FIG. 6 shows a special case of a light intensity curve E k of the interior light with a constant minimum.
  • a light intensity curve as shown, would already be satisfactorily approachable with five values 12 in the case of linear interpolation.
  • the lamp light intensity is basically controlled (rough setting) as a function of time, ie basic light intensities are assigned to certain times of the day, the fine adjustment in the direction of the double arrows in FIG. 4 is controlled by the light intensity of the outside light.
  • the two dependencies can be interchanged, the basic light intensity is specified depending on the outside light, the fine influence on the light intensity E k takes place depending on the time. This results in a simplified possibility for an operator to influence.
  • the non-volatile read-write memory 8 contains a multiplicity of values 11, 12 which define a plurality of functions c1, c2, c2, c4, c5 which can be changed independently of one another.
  • the control signal which the outside light sensor 1-1 emits and which is supplied to the control circuit part (s) 2, 2-1, 2-2, 2-3, and 2-4 depending on four, the A variety of values 11, 12 defined different functions supplied to the four dimmers 4-1, 4-2, 4-3, 4-4 different predetermined phase control signals.
  • the different functions for the control of the respective dimmer or interior light generator are stored together in the one non-volatile read / write memory 8.
  • a variant of the exemplary embodiment in FIG. 8 is that instead of the one outside light sensor 1-1, a plurality of outside light sensors, in the present case four outside light sensors 1-1, 1-2, 1-3 and 1-4, the four control circuit parts 2-1, Control 2-2, 2-3 or 2-4.
  • An outside light sensor, for example 1-2 controls a control shading part, for example 2-2.
  • Such a multidimensional arrangement can also be implemented by means of several different dimmer circuit parts 3-1, 3-2, 3-3 or 3-4. Then a dimmer circuit part, for example 3-1, is controlled by an outside light sensor, for example 1-1. In such an arrangement it is possible not only to vary the interior light depending on the outside brightness, but also depending on the outside light direction, i.e. depending on the cardinal direction or the steepness of the external light striking the external light sensors.
  • FIGS. 9 and 10 each show the same room, which has windows F1, F2 and F3, through which outside light E a can fall into said room E i '. At the same time, cardinal points are shown. Windows F1 and F2 are on the east side, window F3 is on the south side.
  • six interior light generators (artificial light generators) 6-5, 6-6, 6-7, 6-8, 6-9 and 6-10 are attached to the ceiling in a symmetrical arrangement.
  • a pair of sensors 1-5 and 1-6 is arranged in the southeast corner in FIG. 9, by means of which both the outside light intensity E a and its direction can be detected.
  • FIG. 8 An x / y coordinate system is shown in the southwest corner, which illustrates the spatial dependence in space and corresponds to the x / y coordinate system of FIG. 11.
  • six independently controllable dimmer circuit parts 4-5, 4-6, .... 4-10 are therefore to be provided.
  • two independent outdoor light sensors 1-5, 1-6 the first of which is in the east direction and the last one direction south oriented in, is provided, so a common control circuit part 2 can be provided, which from the outside direction of light and the external light luminance E a brightness values E k depending from the memory 8 individually supplies the six dimmer circuit parts for the six dimmer circuit parts. 4
  • EDG electronic ballasts
  • an additional interior light illumination (artificial light) E k (x, y) can now be generated in the room depending on the light intensity and the direction of the light direction in amplitude E k and location dependence x, y is chosen such that it complements the respective incident light E i ' forms.
  • the light 6-6 and the lamp 6-9 would have to be switched on or the brightness increased in the case of the incident light, the remaining four lamps could be switched off or dimmed down to a lower brightness value.
  • This enables uniform daytime and season-independent room lighting E i (x, y) and saves energy at the same time.
  • FIG. 11 shows the spatial dependence of the room brightness E i '(x, y).
  • the cardinal direction drawn in this way forms the orientation such that the maximum of the interior light intensity E i 'is at the window F3 and this light intensity drops to the inside of the room both to the side and to the depth of the room.
  • Figure 11 shows the location-dependent interior light intensity as a curved characteristic surface. If one wishes the aforementioned constant room brightness E i (x, y), which is essentially independent of location and thus guarantees an equal light level at every location in the room, the interior light generator arranged in the room, the location-dependent difference between E i (x, y) and E i ′ (x, y) are applied. This can be imagined with reference to FIG.
  • the artificial light intensity distribution E k (x, y) required to supplement the incident outside light can be determined by specifying it in points.
  • function values 11 which, as explained in FIG. 5, can also define control characteristic curves (functions), define control surfaces (characteristic surfaces) in two dimensions in the present case and can be changed as desired.
  • Each dimmer circuit part 4-5, 4-6, ??, 4-10 which controls one of the interior light generators shown, receives its (light intensity) command variable individually from a control circuit part 2.
  • This can also be a phase angle ⁇ if light bulbs with upstream dimmers are used.
  • the respective individual reference variable is shown, for example, from the incident light on the two Outdoor light sensors 1-5 and 1-6 calculated.
  • sensors can also be used. When using several outside light sensors, each outside light sensor is assigned a limited angular range within which it detects the light intensity (depending on the direction of the outside light). The respective recorded angle ranges per sensor directly or slightly overlap each other, so that a 270 ° detection (only north) is obtained.
  • the elevation angle can also be included with the detected azimuth angle ranges, this corresponds to the steepness of the incidence of light depending on the season. In the case of complete window fronts, the depth of the incident light changes, this can be compensated for by the control according to FIG. 8.
  • each of these interior light generators is assigned an individual control characteristic area (artificial light intensity distribution) E k (x, y).
  • E k artificial light intensity distribution
  • amplitude values 11 for each interior light generator.
  • a light intensity value for each interior light generator is determined individually on the basis of its characteristic characteristic surface and transmitted to the respective dimmer circuit part 4 as a phase angle, frequency value or desired luminous intensity value.
  • the respective individual characteristic surfaces thus form two-dimensional (curved) luminous intensity distributions, which can be adapted to room conditions and window sizes or number of windows by changing their base values 11.
  • a few interpolation points 11 are sufficient for the definition of a two-dimensional characteristic surface if the interpolation between the discrete interpolation points explained at the beginning is used.
  • the two external light sensors 1-5 and 1-6 shown in FIG. 9 are only arranged there by way of example in the southeast corner of the building or room, other attachment options and joint mounting on a roof of a building can also be used for the invention.
