Definitions
- the invention relates to a method and exn designed for lighting system for operating a multi-channel LED module.
- Such methods and dedicated lighting systems are used to control multi-channel LED modules. These are in particular modules with differently colored LEDs such as RGBW (red-green-blue-white) and RGBA (red-green-blue-amber) modules. Due to the different colors, especially red-green-blue, different shades can be achieved by mixing. For this purpose, the channels can be controlled individually.
- RGBW red-green-blue-white
- RGBA red-green-blue-amber
- US 6 552 495 B1 shows a control system and method for generating a desired light through a plurality of red, green and blue LEDs.
- This includes a color sensor that measures the generated light color in a first coordinate system, ie in RGB.
- the signal is transformed by a module into another color coordinate system, which is an xLy coordinate system.
- a second module converts a reference color specified in XYZ coordinates also into xLy coordinates.
- An adder now calculates the difference between the measurement and the reference and passes the result to a controller that uses a driver to control the LEDs so that the difference is compensated.
- the controller is preferably a PI (Proportional Integration) controller.
- US 2008/01 69770 A1 shows a method and system for translating a three-component color signal, preferably given in a CIE scale, to a color signal formed from n primary colors, where n is an integer with n greater than or equal to 4.
- n is an integer with n greater than or equal to 4.
- a CIE standard color chart is used, which consists of 2 color dimensions, which represents 2 of the 3 components of the color signal.
- the n primary colors are formed by n LEDs with different wavelengths.
- points Pl to Pn are entered in the procedure on the CIE standard table as points Pl to Pn.
- at least one point P0 is formed by linear combination of the points P1 to Pn, which is preferably at or in the vicinity of the blackbody curve. Since the point PO is between the points Pl to Pn, triangles can now be formed, each triangle consisting of lines between PO and two adjacent points from Pl to Pn.
- the color signal is entered as point Px and determined by a control unit, in which triangle it is located. It follows, which two points from Pl to Pn next to PO are closest to Px. By means of these three points can now be determined by the control unit, a linear combination whose solution corresponds to the point Px.
- the optimal linear combination for PO is chosen by the control unit to achieve a maximum CRI value and a maximum luminous efficiency, whereby different linear combinations are available in a memory.
- the brightness of the linear combination of the 3 points must be adjusted so that it corresponds to the third component of the color signal.
- the present invention deals with a method of controlling a multi-channel LED module wherein the light emitted from the multi-channel LED module is adjusted to a predetermined color by independently driving the individual channels and the actual emitted light color is returned for control purposes.
- a coarse regulation takes place in which only the channels of a subgroup, in particular two channels, are adjusted independently of each other until the total radiated light color lies within a predetermined tolerance range.
- a fine-tuning takes place in which all channels are adapted.
- Another aspect of the present invention relates to a method of controlling a multi-channel LED module wherein the light emitted from the multi-channel LED module is adjusted to a predetermined color by independently driving the individual channels and the actual emitted light color is returned for regulatory purposes.
- the setting of the predetermined color at the beginning is done exclusively by the independent adaptation of individual channels of a subgroup.
- Each channel of the subgroup is adjusted independently of the others until the parameters set with it exceed a permitted maximum value or fall below a permitted minimum value.
- other non-subgroup channels are adapted for control.
- the predetermined color is preferably given m x, y coordinates in an ICC standard color chart.
- the multi-channel LED module may be a four-channel LED module, in particular an RGBW (red-green-blue-white) or RGBA (red-green-blue-amber) LED module. At least one LED is connected to each channel.
- RGBW red-green-blue-white
- RGBA red-green-blue-amber
- the white channel can be realized by an RGB module. Alternatively, however, it can also be realized by at least one blue LED, wherein in the emission region of the blue LED is a wavelength conversion means which converts at least the wavelength of a part of the leaked radiation into another wavelength.
- the Amber channel is preferably a white channel in which an amber color supplement is added at the exit angle of the light of the connected LED's / LEDs.
- the individual channels can be controlled via PWM (Pulse Width Modulation). This results in the advantage that no control by the drive current is necessary. Therefore, the driving current can be set to a constant value.
- Another advantageous aspect of the invention is the fact that the adjustment of the emitted light of the multi-channel LED module to the predetermined color can be done exclusively by bit comparisons.
- the light color attributed to control purposes can be given in RGB coordinates.
- the RGB coordinates of the recirculated light color can be transformed into x, y coordinates of the ICC standard color chart and a parameter for the brightness for comparison with the predetermined color.
- the coarse regulation preferably takes place via a subgroup of the channels, it being possible for the subgroup to be the red and the green channel.
- the predetermined tolerance range which represents the threshold between the coarse and the fine control, is preferably a multiple of an allowable error value.
- the fine control takes place until the emitted light corresponds as far as the predetermined color that the error, so the deviation is not greater than the allowable error value.
- Control of the blue and white / amber channels can then be done when the set PWM duty cycles of the red and green Channels are above an allowable maximum value or below an allowable minimum value.
- the invention also relates to a lighting system comprising a multi-channel LED module, a control unit and a sensor device.
- the control unit sets the light emitted by the multi-channel LED module light to a predetermined color by independently controlling the individual channels.
- the sensor device returns the actually emitted light color to the control unit.
- a coarse regulation takes place, in which only the channels of a subgroup, in particular two channels, are adapted independently of each other until the total radiated light color lies within a predetermined tolerance range.
- a fine adjustment takes place, in which all channels are adapted.
- the invention also relates to a lighting system comprising a multi-channel LED module, a control unit and a sensor device.
- the control unit sets the light emitted by the multi-channel LED module light to a predetermined color by independently controlling the individual channels.
- the sensor device returns the actually emitted light color to the control unit.
- the setting of the predetermined color is initially performed solely by independently adjusting individual channels of a subgroup. Each channel of the subgroup is adjusted independently of the others until the parameters set with it exceed a permitted maximum value or fall below a permitted minimum value. Instead of the channel with the unauthorized high or low parameter values, other non-subgroup channels are adapted for control.
- the lighting system has a memory.
- the rule may be designed to only perform bit comparisons.
- the sensor device may be an RGB color sensor.
- Fig. 1 is a simplified representation of the erfmdungsgeschreiben method using an ICC standard color chart
- Fig. 2 is a vector diagram that the
- FIG. 3 shows a preferred embodiment of a flowchart of the inventive method
- FIG. 4 shows a schematic exemplary embodiment of the illumination system according to the invention
- Fig. 1 is a simplified representation of the erfmdungsgespecializeden method is shown. The procedure is explained using an ICC standard color chart.
- the ICC standard color chart is rendered in x-y coordinates.
- a color space is shown that has the shape of a triangle.
- this triangle are all human-visible colors defined by an X, Y, Z space. Due to better visualization, this 3-dimensional X, Y, Z space was limited to a 2-dimensional x, y space. This is made possible by omitting the parameter for brightness.
- the ICC standard color chart from Fig.l does not indicate brightness differences. This parameter should therefore be considered separately. Only a color intensity is given, with the border representing the "pure" colors with the highest saturation. Within the triangle are mixed colors.
- the white points are at different color temperatures.
- the edge of the triangle is defined, as already explained, by primary colors that consist exclusively of one wavelength. Some of these are shown in Fig.l. Roughly speaking, at the upper end of the triangle, the color green is at a wavelength of about 520 nm. The right corner is at about 650nm as red defined, bottom left at about 470nm is blue.
- Em channel controls a certain color, whereby more than one LED can be connected to one channel. This means that, for example, several blue LEDs can be connected to the blue channel. In addition, it is also conceivable that additional channels can be realized. This can be achieved by connecting different colored LEDs to one channel. For example, let yourself be Achieve magenta channel by connecting at least one blue and at least one red LED.
- a mixture of the individual luminous colors is achieved by suitable means, preferably by a mixing disk.
- a light color corresponding to a color at point A is initially generated by a four-channel RGBA LED module.
- the predetermined target color corresponds to that at point C.
- a coarse regulation is therefore first carried out until the emitted light color lies within a certain tolerance range. This is represented here by the circle around point C.
- red and green are varied. Blue and Amber (amber) remain constant.
- red and green roughly corresponds to a change of the total emitted light in the y-direction.
- red roughly corresponds to a change in the total emitted light in the x direction. This means that by independent rules of red and green independent dimensions in the color space are varied.
- red LED means a shift in the x direction.
- a gain of the amber LED is a shift against that of a gain of the blue LED, with the blue portion of the y being less.
- the coarse control is then replaced by a fine control when the total generated light color has arrived at point B, following the white arrow, which is on the circle around the target point C.
- a fine control a smaller step size is used to change.
- all channels are varied independently. An approximation can now be achieved by shifting in four different directions, the four directions are shown in Figure 2.
- the regulation is then terminated when the shortcut is not greater than a legal error value.
- Fig. 3 shows a preferred embodiment of a flowchart of the inventive method.
- step A an initialization takes place.
- the essential parameters of the erfmdungsgedorfen method are set.
- the step by step adjustment is set to coarse (fastStep). This means that a coarse regulation takes place at least in the first pass of the flowchart.
- step B it is checked whether a further adaptation is necessary. In this case, it is determined whether the inaccuracy of the actual value (x, y) to the target value (Targetx, Targety) is within an allowable error value (error). If this is the case, then the process is completed.
- step C If, in step C, all four channels (RGBW) are less than half of the maximum allowable PWM value, then it is determined for each channel if the channel is off.
- step D1 the channels are set with the respective PWM pulse widths.
- the RGB actual values are transformed into (X, Y, Z) coordinates. These are then converted into x, y, z coordinates. This results in the x-actual (x) and y-actual (y) values.
- step E an adjustment of the actual x value is performed by changing the red channel and the y actual value by changing the green channel.
- first x-actual (x) is compared with x-target (targetx) in El. If X-Is is too small, red in E2 is increased by a fastStep.
- the specified tolerance range is a multiple K of the permitted error value "error”.
- K can represent a variable which becomes smaller as the actual value approaches the setpoint as the actual value increases. This reduction of K is done each time a new approach has been reached. When reaching a new approximation level, of course, the change increment of a color is reduced to a smaller one.
- steps Ell to E15 an analogous procedure is carried out in the event that the actual x value is too large.
- steps E21 to E35 a procedure analogous to E1 to E15 is carried out for a comparison between the actual y value and the y setpoint with corresponding adaptation of green.
- steps F to I is now checked whether the PWM pulse width of the red and / or the green channel xn is an illicit high or low range. If this is the case, then the blue instead of the red one, or the white and the blue channel instead of the green channel, is regulated.
- step F it is thus checked whether the pulse width set with red lies above a maximally permitted value. If this is the case, the X actual value and the Y actual value are adjusted by adjusting the blue channel.
- m Fl is the PWM pulse width of red above a maximum permissible value
- this is set to the maximum permissible value.
- a comparison of the actual value of the x and the actual value of the y which proceeds analogously to E1 to E35, follows whether these values are below or above the desired values. However, not the red or the green channel is adjusted, but the blue channel. Again, there is a decision as to whether the pace should be set from blue to faststep or finestep. This decision is made again depending on whether the x actual value and y actual value are within a K fold of the tolerance range "error".
- step G it is checked whether red is below a minimum allowed value UL. If this is the case, an adjustment of the x actual value and the y
- step Gl If, in step Gl, the PWM pulse width of red is below the UL
- step G2 the step speed of red is set to 1.
- the PWM pulse width of Red is less than 1, then it is set to the value 0 in G4. Again, a comparison of x-actual and y-actual analogous to FIl to F45 follows, whether these values are below or above the nominal values. In each case, the blue channel is adjusted again.
- step H it is checked whether the pulse width of green is above a maximum permissible pulse width. If this is the case, then the actual x value and the y actual value are changed by changing the pulse width of blue and white customized. It is determined in H1 whether the PWM pulse width of green is above the maximum permissible PWM value. If this is the case, the value in H2 is set to the maximum permissible PWM value. Again, an adaptation to the type described in steps FIl to F45 is made, now not only blue is adjusted, but blue and white together. It should be noted that if the actual x-value is too small, blue and white in H11-H15 are reduced by one increment and increased by one increment if the actual x-value in H21-H25 is too large.
- step I it is checked whether the pulse width of the green channel is below a minimum allowed value UL. If this is the case, the x-value and the y-value are adjusted again by adjusting the white and the blue channel.
- step 12 the step speed is set from green to 1. If the PWM pulse width of green is less than 1, this is set to the value 0 in FIG.
- step K it is determined whether the PWM pulse width of blue is above the maximum allowable PWM value. If this is the case, the value is set to the maximum permissible PWM value. It is then checked in K3 whether the PWM pulse width of green is below the UL value. If this is the case, the step speed of blue is set to 1. If the PWM value of blue is less than 1, then it is set to the value 0.
- step L the same process described in step K for blue is now performed for white.
- step M is jumped back to the start in step B. This forms a loop and the method can be performed until a given error value is not exceeded.
- the lighting system 1 has a control unit 2.
- This in turn can consist of a low-cost processor, since thanks to the method according to the invention only simple bit comparisons must be made.
- higher-quality processors such as Cordic processors or other types such as digital signal processors, or ASICs can be used.
- the control unit 2 is connected via a bus 6 with an LED module 3.
- the bus here consists of 4 of independent channels 5, each channel regulating a luminous color.
- the LED module is embodied here as an element which comprises four differently colored LEDs 4. These can be red, green, blue and white. Alternatively or in addition to the white LED, however, an amber LED can be used. In addition, it is conceivable to use several instead of one LED of one color, which are connected to the same channel 5.
- the white channel can be realized by a separate RGB module. Alternatively, however, it can also be realized by at least one blue LED, wherein in the emission region of the blue LED is a wavelength conversion means which converts at least the wavelength of a part of the leaked radiation into another wavelength.
- an amber channel is to be used, this is preferably a white channel m of the embodiment described above, in which an amber additive is added at the exit angle of the light of the one or more LEDs.
- the emitted light from the LED module 11 is mixed by suitable means, for example by a lens so that a uniform luminous color is formed.
- the invention is also not limited to LEDs. It can be used in place of any other type of colored lights.
- a sensor device 7 is connected to the control unit 2. This is an RGB color sensor. It measures the light 11 emitted by at least one LED module. Thanks to the three independent measuring sizes, all the colors that can be generated by combining the three colors can be measured, as well as the brightness. Nevertheless, it is conceivable to connect a further brightness sensor to the Regelemheit, for example, a daylight sensor.
- the three independent measured variables are transmitted via the interface 8 to the control unit for the adaptive control of the LEDs described above.
- the rule unit 10 also has an interface 10. This can be as
- User interface be formed.
- it may be an input device by means of which a user of the rule transmits a color setpoint and possibly a brightness value.
- the luminous color of the LEDs 4 could be adapted to the set value.
- the interface 10 may also be an interface to a central control unit.
- the latter may be a programmable timer that cycles through different light patterns at different times of the day.
- the lighting system may include a memory 9.
- set color specifications can be stored.
- the lighting system can also be programmed for different temporally changing luminous properties.
