Definitions

  • the invention relates to a method for frequency-variable control of the light color and/or the luminous flux (or the brightness) of a lighting system.
  • the invention also relates to a lighting control unit, comprising a storage medium on which program logic for carrying out the method according to the invention is stored, and a microcontroller connected to the storage medium.
  • the invention relates to a lighting module, comprising a lighting system and a lighting control unit according to the invention.
  • the invention relates to a lighting arrangement comprising a number of individually controllable lighting modules according to the invention.
  • DE102013207961 discloses a method for changing the color locus of the visible light emitted by an LED module, the LED module having at least two parallel LED lines, the emission spectrum of the LED lines differing, the LED lines alternating with constant current are operated, and to change the color locus the ratio of the switch-on durations of the LED lines is changed, preferably while keeping the sum of the switch-on durations of all LED lines constant.
  • Lighting systems are known from the prior art in which the emitted light color and the brightness are controlled by pulse width modulation, which is controlled by a microcontroller.
  • the microcontroller has a timer and an associated comparator for each light source to be controlled, with each light source being activated for a specific time period within a clock period. This period of time is recorded by comparing a predefinable timer target value with the actual timer value using the comparator and the respective light source is controlled accordingly.
  • the clock rate of such a microcontroller can be, for example, a frequency of 1 kHz, with sub-intervals still being able to exist within such an interval, which enable the combination of RGB color components. When divided into four subintervals (see 1 ) the individual light sources can be switched off with a frequency of up to 4kHz.
  • the minimum switch-on time is limited due to the minimum sub-interval of the clocking of the microcontroller, it may be necessary, for example for dimming the emitted light, to increase the clock duration in order to reduce the proportion of the minimum sub-interval in the total time.
  • This also allows different ratios of the Achieve a mixture of the light colors involved.
  • the operating frequency of the microcontroller can be reduced to 500 Hz by halving it.
  • figure 2 shows such a transition, in which a clock interval now comprises 8 minimum time sub-intervals.
  • the proportion of the light color "red" in the emitted light distribution is to be reduced or dimmed (here halved).
  • the remaining light colors green and blue should remain unchanged.
  • the rigid mode of operation of the microcontroller is accompanied by the problem that beats can occur in the radiation of largely synchronously clocked lighting systems, which can be visible to the human eye and have a disruptive effect.
  • the method according to the invention makes it possible to vary the light color and the brightness of the light emitted by the lighting system without causing undesired transitional superimpositions or accepting beating of the light emission of different lighting systems.
  • the microcontroller can be designed in a particularly simple manner, since only one light source is active at a time.
  • the sum of all time periods can preferably also be less than 10 ms in the dimmed state in order to remain above the flicker merging frequency.
  • the only thing that needs to be observed exactly is the relationship between the time periods. In this way you can achieve significantly more precise resolutions and thus color settings with the same hardware.
  • the "light off" time span can also be divided into several time spans and inserted between the time spans of the individual colors. Since this method also manages with just one counter, inexpensive microcontrollers can be used.
  • colored light sources it is also possible to control white light sources or white light sources, in particular LEDs, with different color temperatures.
  • the microcontroller only uses a single comparator and/or a single timer to control the at least two light sources.
  • the reference time duration is assigned to the light source that is active for the shortest time during the clock interval, with the switch-on durations of the remaining light sources being divided by Multiplication of the reference switch-on time is set by an individual factor greater than 1, each factor being weighted according to the ratio of the calculated switch-on time ratios.
  • the shortest switch-on time is normalized to the value "1", so to speak, and the remaining switch-on times are given a factor greater than or equal to 1, the actual times being calculated by multiplying the respective factor by the reference time.
  • the microcontroller can have a minimum switch-on period that corresponds to the lowest period of time that can lie between a switch-on process and an immediately subsequent switch-off process, with the following applying to the reference period: tref ⁇ tmin.
  • This minimum switch-on time is specified by the technical limitations of the microcontroller and can be taken from the technical data sheet of the microcontroller used in each case or derived from it.
  • the reference time period is determined as a function of a random variable or is set to a randomly selected new value and the other time periods are adjusted in proportion. This not only prevents the lamps from oscillating with each other, but also error-free dimming down to the 0.1% range by increasing the "light off" period and continuously changing the frequency.
  • the random value can be determined with the aid of a noise generator, for example.
  • the reference period is selected in such a way that the resulting cycle period t T is a maximum of 10 ms. In this way it can be ensured that the human eye does not perceive the individual switch-on durations and operational pause durations per se, but only detects the temporal average of the sequence of these durations. In this way the clock frequency stays above the flicker merging frequency.
  • the lighting system for the optical transmission of information is controlled by the sequential sequence to be calculated in step b) being manipulated, taking into account an information signal to be transmitted, the information signal being selectively selected in the temporal sequence of the resulting according to step c).
  • Switch-on durations and possibly operational pause durations are encoded in the light distribution emitted by the lighting system.
  • the coding can be implemented, for example, by specifically specifying the sequence of emission by the individual light sources and by specifically arranging pauses within a clock cycle. In this way, the degrees of freedom that are given by the present inventive method in the emission of the light distribution can be used in a targeted manner without influencing the emitted light distribution on average and without the coding being visible to the human eye on the way Light distribution affects.
  • the lighting system has at least three light sources, namely a light source for emitting red light, a light source for emitting green light, and a light source for emitting blue light.
  • a light source for emitting red light a light source for emitting red light
  • a light source for emitting green light a light source for emitting blue light.
  • the invention also relates to a lighting control unit, comprising a storage medium on which program logic for carrying out the method according to the invention is stored, and a microcontroller which is connected to the storage medium and is set up to receive the input signal and the light color to be emitted and/or Specify lighting intensity of the lighting system using the program logic according to the inventive method.
  • the invention relates to a lighting module, comprising a lighting system and a lighting control unit according to the invention for controlling the lighting system, the lighting system comprising at least two light sources of different light colors.
  • the at least two light sources are LED light sources.
  • the invention relates to a lighting arrangement comprising a number of individually controllable lighting modules according to the invention.
  • these lighting modules can be set up to communicate with one another.
  • beats and undesired superimpositions between the light distributions emitted by the lighting modules can be avoided by the features already mentioned.
  • FIG. 1 and 2 show figures 1 and 2 the known prior art, in which the individual light sources are controlled separately by means of a PWM modulation, in the case of a dimming process it is necessary to greatly reduce the clock rate of the light control and the transition problems mentioned at the outset can occur when the clock rates change.
  • the horizontal axes are in the figures 1 and 2 the timelines.
  • two images are superimposed in the two figures - namely above the counting process associated with the individual durations, within which a timer reaches a predetermined value and a comparator is used to determine whether this value has been reached, and below the actual emission of light by a light source in each case , where the light sources R, G and B designate the light colors red, green and blue.
  • the hatched areas denote the switched-on state of the light sources.
  • the proportion of the red light R can be reduced, this can be done in a simple manner, as based on the second clock period T T2 of figure 3 is shown.
  • the red light component can be dimmed simply by increasing the green and blue on-time periods.
  • the pause duration can also be increased so that the emission of the green and blue light remains unchanged on average over time.
  • the light source 2 that is active for the shortest time during the clock interval is assigned the reference time duration t ref
  • the Turn-on durations of the remaining light sources by multiplying the reference turn-on duration t ref by an individual Factor greater than 1 is set, each factor being weighted according to the ratio of the calculated switch-on time ratios V R , V B , V G .
  • lighting system 1 is controlled for the optical transmission of information by manipulating the sequential sequence Seq to be calculated in step b), taking into account an information signal S I to be transmitted, with the information signal S I being generated by targeted selection of the temporal sequence of the according to step c), the resulting switch-on durations t eR , t eB , t eG and, if applicable, the operating pause durations t P are coded into the light distribution emitted by the lighting system 1 .
  • FIG 12 shows an exemplary representation of the operation of the invention in the form of a flow chart.
  • the invention relates to a method and a method for driving multicolored LEDs with 2 to n colors or color temperatures, where the brightness can be viewed as an additional color. It relates to an optimized color control in order to achieve maximum resolution of brightness and color with an optimal light merging frequency and the best possible temporal load distribution for the required power supply. With the condition that the individual output currents of the color LEDs are never allowed to overlap, it is guaranteed that currents higher than the rated current are never drawn from the power supply unit.
  • the first block determines which channels are involved in the desired mixing ratio and which of these channels has the smallest share in it.
  • the optimal pulse output time is assigned to the smallest part (preferably in the range 1-10us). Based on this, the necessary output times of the other channels are calculated.
  • the channel with the longest output time is determined. If this is greater than the maximum output time (preferably 0.5-1ms), it is split into two parts and interleaved with the other channels.
