Definitions

  • the invention relates to a lighting control system according to the preamble of claim 1.
  • Such a lighting control system of the applicant has become known through public prior use. It is a lighting control system, which may have one or more controls in the form of computers.
  • the controller is connected to a variety of lights through a network. To the controller can be connected lights that have only one bulb, but equally also lights that have multiple, different colored bulbs.
  • the bulbs which may also be referred to as light sources, may be LEDs, colored fluorescent lamps or any other type of conventional or future bulbs.
  • the controller which may be formed by a conventional PC or a specially adapted computer, run a software as commercially available from the applicant under the name Light-Studio.
  • the software offers the possibility of making numerous adjustments to the parameters of the individual luminaires via a user interface.
  • an operator may determine by means of an input device, eg a conventional computer mouse, that a certain luminaire should generate a certain mixed color.
  • an input device eg a conventional computer mouse
  • a specific luminaire to be addressed for example a red, a green and a blue light-emitting diode (LED), can be set by selectively addressing the three individual light sources for virtually any mixed color of a total luminous flux.
  • LED light-emitting diode
  • the light emitted by the different light sources is mixed together into a mixed light with the aid of suitable mixing means, such as reflectors, diffuser plates or due to geometrical arrangements of the LEDs, as is well known in the art.
  • suitable mixing means such as reflectors, diffuser plates or due to geometrical arrangements of the LEDs, as is well known in the art.
  • the light leaving the luminaire can be described as the total luminous flux and a total color flux can be assigned to this total luminous flux.
  • the light generates, for example, white light. If only the red LED is addressed while the green and blue LEDs remain off, the lamp generates red light.
  • the invention is therefore based on the object, as a known presumed lighting control system according to the preamble of claim 1 such that it can be used in a particularly variable manner.
  • the invention solves this problem with the features of claim 1, in particular with those of the characterizing part and is accordingly characterized in that the controller has a weighting device, with the adjusted mixed color while maintaining this mixed color, a luminous flux of at least one light source is changeable.
  • the principle of the invention consists essentially in providing a weighting device in a luminaire control system with a color selector. After the user has set a mixed color for a particular luminaire, or for all luminaires connected to the luminaire control system together, a weighting can be carried out below by means of which light sources, or by means of which light fractions, this mixed color is to be generated.
  • a total luminous flux is generated by a plurality of light sources.
  • a lamp has a red, a green and an amber LED.
  • the mixed color of the total luminous flux can now be selected, for example, amber.
  • this mixed color can be generated by turning off the red and green LEDs and only the amber LED is turned on.
  • the amber LED can be switched off and only the red and the green LED, in equal parts, for example, be addressed with 100% or 75% of their maximum power.
  • all three LEDs, ie the red, the green and the amber LED are each driven at 50% of their maximum intensity. As a result, the mixed color of the total luminous flux is practically indistinguishable in all three described driving scenarios.
  • the total luminous flux contains no red or green light components.
  • red or green LED luminous flux components For example, if you want to illuminate a wall amber-colored in the area of a sales area, and if there are red or green goods near the wall that should be emphasized with emphasis on their own natural colors, it may be useful to obtain the amber-colored overall light of red and green LED luminous flux components. This can be done by changing the luminous flux of the red or green light source using the weighting means. At the same time, the weighting device ensures that, despite the change in individual luminous fluxes, individual light sources retain the mixed color.
  • lamps can be constructed in the manner according to the invention, which consist of numerous LEDs or other light sources of different colors, and which may have, for example, five or six LEDs of different colors.
  • a white mixed color can be set and emphasis on certain spectral components an emphasis on colored goods done.
  • the invention relates to building lights intended to be fixedly mounted on a building wall, either for ceiling, wall or floor installation or for attachment to a radiator, e.g. in a power rail.
  • Such lights are used in particular for the illumination of building surfaces in the interior or exterior or for the illumination of goods or objects, such as statues or pictures or conventional merchandise.
  • Inventive luminaire control systems are particularly suitable for the field of shop lighting, but can equally serve to illuminate any other surfaces.
  • passages or areas of a building can be illuminated with an adjustable mixed color, while z. B. architectural details, eg. B. externally visible window sills, a certain, differing from the color of the passages color, can be emphasized by admixing spectral light components of this particular color.
  • each individual light source of each luminaire connected to the luminaire control system is individual approachable.
  • the wording according to which "the light sources can be controlled to set or change their luminous flux to be emitted” also encompasses those luminaires in which several differently colored light sources can only be addressed or controlled in total. It is crucial that by entering a mixed color on the controller, the user can choose which color has the total luminous flux. For this purpose, the individual light sources from the controller, in particular via a signal line, can be addressed.
  • the weighting means may be in the form of one or more controllers, e.g. Sliders or knobs, as one knows this, for example, from equalizers, be trained.
  • the regulators can be assigned to the colors of the different illuminants.
  • a controller for adjusting the luminous flux of the green-colored a controller for adjusting the red-colored and a controller for adjusting the amber LED can be provided. If the user has set the mixed color amber in the aforementioned example of a luminaire with three LEDs, and he wants to emphasize the proportion of green light to emphasize green goods, he can generate a maximum possible green luminous flux by pressing the controller associated with the green LED.
  • the weighting device is preferably assigned an arithmetic unit, which automatically ensures that when the controller for the green LED, the controller for the red LED mitfoli in the same extent and at the same time goes back the controller for the amber LED. An automatically calculated movement of the controllers takes place in order to maintain the set mixed color.
  • the controller may have a display direction that indicates or represents the spectral composition of the total luminous flux - corresponding to the respective current setting of the weighting device - or the spectral composition of the partial luminous fluxes emitted by the individual light sources.
  • the three differently colored LEDs having light for example, the three LEDs in a coordinate system whose x-axis represents the wavelength can be displayed and the corresponding intensity gradients, depending on the current position of the controller, are displayed.
  • the total current or total luminous flux thus the spectral distribution of the light emitted by the lamp as a whole, can be displayed in this way.
  • the controller may cause a real-time change in the luminous fluxes emitted by the individual light sources as a result of the color selector or weighting device being actuated by the user.
  • the invention may be a light control system which communicates signals according to the DALI protocol.
  • the lighting control system according to the invention relates in particular to a network of luminaires, in which a plurality of luminaires are connected via a signal line to one or more controllers.
  • the control system according to the invention can also be part of a single luminaire and, for example, for this purpose have a color selection device and weighting device attached directly to a housing on the lamp.
  • the lighting control system 10 is for controlling a plurality of lights. Based Fig. 1 will first be exemplified that a lamp 11 may be attached, for example, to a ceiling 12 of a sales room of a building and the illumination of a wall surface 13, possibly also a bottom surface 14, and in particular of goods 16 may serve, for example, on a shelf 15th are arranged in front of the wall 13.
  • a luminaire 11 of a luminaire control system according to the invention can likewise be used for wall-side or bottom-side installation or for illuminating exterior surfaces.
  • a luminaire 11 as part of a luminaire control system 10 according to the invention is initially based on Fig. 2 to explain. Accordingly, a plurality of differently colored light sources on a support plate T, in the embodiment of the Fig. 2 a red LED 18, a green LED 19 and an amber LED 20 are arranged. From each of the light sources is a partial luminous flux 21a, 21 b, 21c, which is indicated only schematically by arrows.
  • Fig. 2 the lamp 11 is connected via a signal or control line 24 to a controller 25.
  • the controller 25 may be, for example, a conventional computer or a specially adapted controller.
  • To the controller 25 first belongs a color selector 26, which in Fig. 2 only very schematically indicated as a color wheel.
  • a color wheel 26 In the color wheel 26 are described with the letters b, g, r blue, green and red areas of the entire, can be generated with the lamp 11 color spectrum.
  • the color wheel 26 also includes different shades of white and mixed tones.
  • a in Fig. 2 not shown cursor or the like position indicator can be positioned within the color wheel 26 and by selection, for example by clicking with a mouse button, a mixed color of the total luminous flux 17 can be set.
  • the controller 25 has a weighting device 27 which, in the exemplary embodiment, consists of three individual controllers 28a, 28b. 28c exists.
  • the controllers are designed in the manner of sliding controls with control buttons K, which can be moved along the indicated double arrows.
  • a display unit 31 Above the three regulators, a display unit 31 is shown, which displays a spectral profile 32 of the luminous fluxes generated by the luminaire 11 as a function of the choice of the mixed color and the setting of the weighting device.
  • the controller 25 is also associated with an only indicated arithmetic unit, which can be provided for example by a conventional computer. By addressing the regulators 28a, 28b, 28c. For example, the spectral composition of the luminous flux 25 can be changed without the previously set mixed color undergoing a change. This will be explained below with reference to FIG. 3 to FIG. 5 be explained:
  • the Fig. 3 to 5 refer to the embodiment of a lamp 11 according to Fig. 2 in which a green, an amber and a red light source, z. B. in the form of light emitting diodes or fluorescent lamps are provided.
  • the embodiment of the Fig. 3 to 5 will be described as being a lamp with a red, a green and an amber LED, although the ones below to be explained in the Fig. 3 to 5 spectral characteristics are significantly wider than in currently commercially available LED's, in contrast, have narrow band spectra.
  • the description of Fig. 3 to 5 is intended only to assist the understanding of the invention, it being understood by those skilled in the art that any suitable light source may be used.
  • Fig. 3 shows the spectral intensity profile, which is generated with set mixed color Amber, if only the amber light source, eg. B. LED, is controlled and the red and the green LED are turned off.
  • the resulting spectral curve is in Fig. 3 denoted by 33.
  • the green LED associated controller 28a of the weighting device 27 can be actuated, and, based on the Fig. 2 , for example, be shifted upwards. As a result, the green LED is first turned on and then increasingly switched on, approximately until the in Fig. 4 denoted by 34 a, dashed curve of the generated by the green LED 19 luminous flux 21 b is reached.
  • the green LED is switched on, the red LED is automatically switched on, and the amber colored one LED switched off.
  • the total spectral characteristic 33 resulting from the summation of the individual partial light streams 34a, 34b should remain essentially unchanged. This ensures that the set color (Amber) can be maintained.
  • the total spectral characteristic 33 resulting from the summation of the individual partial light streams 34a, 34b does not substantially change.
  • the overall spectral response may well change without the mixed color changing. This is determined by the dominant wavelength perceived by the human eye.
  • the luminaire controller according to the invention leaves the mixed color of the total luminous flux 17 unchanged, while it can change the spectral components.
  • the composition of the mixed light is thus changeable.
  • certain objects or surfaces of a particular color can be emphasized or emphasized.
  • the aim of a change in the color of the mixture may be to avoid a certain color emphasis.
  • Certain architectural details or other, color-different areas or passages of surfaces to be illuminated can thus remain unattended or get into the background. Alternate emphasis and understatement may also be desired as part of a scenographic lighting.
  • a luminaire according to the invention will have five or more light sources, in particular LEDs, of different color.
  • it is envisaged to provide at least one red, one green, one blue, one yellow, one cyan, one amber and one white LED.
  • this makes it possible to generate white-colored total light 17 by a luminaire 11, and still highlight objects or surfaces of a particular color by emphasizing certain spectral color components.
  • the schematically indicated computing unit 30 can automatically calculate within which limits spectral components of specific light sources can be replaced by other spectral components. For example, it may be conceivable for a particular selected mixed color that a certain spectral component may not be taken out without the mixed color changing. Accordingly, a corresponding, associated with this LED controller could also be blocked, or not be responsive. On the other hand, in a preferred embodiment of the invention, it is conceivable that a controller allows the connection or dimming of a specific light color only to a certain extent. Thus, in the embodiment of the Fig. 4 clearly that the green LED can only contribute a maximum luminous flux according to the dashed curve 34a. If the luminous flux of the green LED further increased, the respect Fig. 4 left portion of the dashed curve 34a beyond the curve 33 shown in solid lines and thus possibly change the mixed color.
  • Fig. 5 apparent spectral intensity distributions 34a, 34b and 34c of the individual Illuminants, namely the green, the amber and the red LED, have an exaggerated there shown, very broad, substantially bell-shaped, almost gaussian spectral distribution. This also applies to the spectral distributions denoted 34a, 34b in FIG Fig. 4 and the total spectral luminous flux distribution indicated at 33. It should be noted that such, in the form of wide bells pronounced spectral distributions in the currently commercially available on the market bulbs may fluorescent lamps, but not be attributed to LED's. LED's emit light with a spectral intensity curve that turns out to be much narrower than in the 4 and 5 shown.
  • Fig. 7 shows the light of the Fig. 6 with the red and green LEDs turned off and the amber LED turned on.
  • the spectral profile of the partial luminous flux emitted by the amber LED is denoted by 34c.
  • the mixed color of the total luminous flux according to Fig. 7 corresponds to that of Total luminous flux of the luminaire in a switching state according to Fig. 6 ,
  • the spectral intensity distributions are as out Fig. 6 seen in LED's so narrow formed that no overlap occurs.
  • the principle according to the invention can equally be used.
  • very narrowband green, amber and red LEDs due to spectral sensitivity or sensitivity of the human eye, which includes only red, green and blue color receptors, there is a corresponding spectral overlap in the human eye.
  • red and green light generated in each case by an LED, generates, and thus finds in the range of wavelength at about 583 nm (corresponding to the color amber) practically no beyond the background noise intensity of the luminous flux, the human eye takes the sum the green and the red light are true as amber light.
