Definitions

  • the invention relates to a method for variable-frequency control of the light color and / or the luminous flux (or the brightness) of a lighting system.
  • the invention further relates to a lighting control unit, comprising a storage medium on which a program logic for carrying out the method according to the invention is stored, and a microcontroller connected to the storage medium.
  • the invention also relates to a lighting module comprising a lighting system and a lighting control unit according to the invention.
  • the invention further relates to a lighting arrangement comprising a number of individually controllable lighting modules according to the invention.
  • the microcontroller has a timer and an associated comparator for each light source to be regulated, with each light source being activated for a certain period of time within a clock period. This period of time is recorded by comparing a predefinable timer setpoint with the actual timer value by means of 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 that enable the combination of RGB color components to be present within such an interval. With a division into four sub-intervals (see Fig. 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 timing of the microcontroller, it may be necessary, for example, to increase the cycle time to dim the emitted light in order to reduce the proportion of the minimum sub-interval in the total time.
  • This also enables 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. In this, for example, the proportion of the light color "red" in the emitted light distribution is to be reduced or dimmed (in the present case halved). The remaining light colors green and blue should, however, be retained unchanged.
  • the rigid mode of operation of the microcontroller is associated with the problem that pulsations can arise in the radiation from lighting systems that are largely synchronized, which can be recognized by 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 overlaps or without having to accept fluctuations in the light emission from 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 stay above the flicker fusion frequency. Only the relationship between the time spans has to be strictly observed. This way you can use the same hardware can achieve much more precise resolutions and thus color settings.
  • the "light off" time period can preferably also be divided into several time periods and inserted between the time periods of the individual colors. Since this method also requires only one counter, inexpensive microcontrollers can be used.
  • colored light sources white light sources or white light sources, in particular LEDs, can also be controlled with different color temperatures.
  • the microcontroller only uses a single comparator and / or a single timer to control the at least two light sources.
  • step b) when calculating the sequential sequence according to step b) in the case of activation of at least two light sources within the clock interval of that light source that is active for the shortest time during the clock interval, the reference time period is assigned, the switch-on periods of the remaining light sources being Multiplication of the reference switch-on duration with an individual factor greater than 1 is established, with each factor being weighted according to the ratio of the calculated switch-on duration ratios.
  • the shortest switch-on time is standardized 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 with the reference time.
  • the microcontroller has a minimum switch-on time period that corresponds to a lowest time period that can lie between a switch-on and an immediately following switch-off process, the following applies to the reference time period: tref tmin.
  • This minimum switch-on time is specified by the technical limitations of the microcontroller and can be taken from or derived from the technical data sheet of the microcontroller used.
  • the reference time duration can be determined as a function of a random variable or to be set to a randomly selected new value and the other time periods to be adjusted in proportion. This not only prevents the lamps from oscillating with one another, but also achieves error-free dimming down to the 0.1% range by increasing the "light off" period and a continuous frequency change.
  • the random value can be determined, for example, with the aid of a noise generator.
  • the reference time period is selected such that the resulting cycle time 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 periods and periods of break in operation per se, but only records the time average of the sequence of these periods of time. In this way, the clock frequency remains above the flicker fusion frequency.
  • the lighting system for the optical transmission of information is controlled by manipulating the sequential sequence to be calculated in step b), taking into account an information signal to be transmitted, the information signal being manipulated by targeted selection of the temporal sequence of the resulting according to step c) Switch-on times and possibly periods of break in operation is coded into the light distribution emitted by the lighting system.
  • an optical sensor is provided for detecting an information signal, in that the sensor is set up to detect the coded light distribution emitted by an illumination system.
  • the coding can be implemented, for example, by specifically defining the sequence in which the radiation is emitted 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 method according to the invention in the emission of the light distribution can be used in a targeted manner without influencing the emitted light distribution in the mean value and without the coding affecting in a manner visible to the human eye Light distribution affects.
  • the lighting system has at least three light sources, namely a light source for radiating red light, a light source for radiating green light, and a light source for radiating blue light.
  • a light source for radiating red light a light source for radiating red light
  • a light source for radiating green light a light source for radiating blue light.
  • the invention further relates to a lighting control unit, comprising a storage medium on which a 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 the lighting intensity of the lighting system using the program logic according to the method according to the invention.
  • the invention also 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 further relates to a lighting arrangement comprising a number of individually controllable lighting modules according to the invention. These lighting modules can in particular be set up to communicate with one another. In addition, the already mentioned features can avoid pulsations and undesired overlapping between the light distributions emitted by the lighting modules.
  • the portion of the red light R is reduced, this can be done in a simple manner, as based on the second clock period T T2 Figure 3 is shown.
  • the red light component can be dimmed by simply increasing the green and blue switch-on times.
  • the duration of the pause can also be increased so that the emission of the green and blue light remains unchanged over time.
  • V G 2.2
  • V B 3.3
  • t eG 2.2 ⁇ s
  • t eB 3.3 ⁇ s
  • t P 2.2 ⁇ s
  • T T2 8.7 ⁇ s.
  • This temporal extension of the switch-on periods within the second cycle period T T2 is shown in FIG Figure 3 clearly recognizable by comparison with the auxiliary lines L1, L2 and L3.
  • the reference time duration t ref is assigned, the Switch-on periods of the remaining light sources by multiplying the reference switch-on period t ref by an individual one 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.
  • the illumination system 1 is driven for optical transmission of information can be provided by taking into account an information to be transmitted signal S I in step) b to be calculated sequential sequence Seq is manipulated, wherein the information signal S I through targeted selection of the temporal sequence of the according to step c) resulting on-time durations t eR , t eB , t eG and, if applicable, operational idle durations t P are encoded into the light distribution emitted by the lighting system 1.
  • FIG Figure 5 shows an exemplary illustration of the mode of operation of the invention in the form of a flow chart.
  • the invention is described in very general terms, in other words with a view to the diagram according to FIG Figure 5 described:
  • the invention relates to a method or a method for controlling multicolored LEDs with 2 to n colors or color temperatures, wherein the brightness can be viewed as an additional color. It concerns an optimized color control in order to achieve maximum resolution of brightness and color with an optimal light fusion 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 never overlap, it is guaranteed that currents higher than the rated current will never be drawn from the power supply unit.
  • the control takes place by sequential output of the channels, for example: the three colors R, G, B and H (brightness). In the first block it is determined which channels are involved in the desired mixing ratio and which of these channels has the smallest share in it.
  • the smallest portion is assigned the optimal pulse output time (preferably in the range 1-10us). Based on this, the necessary output times for 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 divided into two parts and nested with the other channels.
