    • There is described a lighting system. The lighting system comprises a voltage source (12) configured to generate a constant direct current adapted to supply a plurality of lighting modules (20a..20n). Moreover, the system comprises a number n of electronic switches (SWa..SWn), wherein each electronic switch (SWa..SWn) is configured to selectively connect a respective lighting module (20a..20n) to the voltage source (12) as a function of respective drive signals ( PWMa..PWMn ) generated by a control unit (102). A current sensor (104) is connected in series with the voltage source (12), in order to detect a measurement signal (CS) indicative of the current provided by the voltage source (12).
      Specifically, the control unit (102) varies the drive signals ( PWMa..PWMn ) , such that:
      - in a first instant, all lighting modules (20a..20n) are connected to the voltage source (12); and
      - during a sequence of (n - 1) instants, each time a different set of lighting modules (20a..20n) is connected to the voltage source (12).
      The control unit (102) then determines the current flowing through all lighting modules (20a..20n) as a function of the measurement signal (CS) detected in the first instant, and determines the currents which flow through the various lighting modules (20a..20n) as a function of the measurement signals (CS) detected during the sequence of instants.
    • 描述了照明系统。 照明系统包括电压源(12),该电压源(12)被配置为产生适于供应多个照明模块(20a..20n)的恒定直流电。 此外,该系统包括n个电子开关(SWa ... SWn),其中每个电子开关(SWa ... SWn)被配置为选择性地将相应的照明模块(20a..20n)连接到电压源(12) 作为由控制单元(102)产生的各个驱动信号(PWMa..PWMn)的函数。 电流传感器(104)与电压源(12)串联连接,以便检测指示由电压源(12)提供的电流的测量信号(CS)。 具体而言,控制单元(102)改变驱动信号(PWMa..PWMn),使得: - 在第一时刻,所有照明模块(20a..20n)连接到电压源(12); 和 - 在(n-1)个时刻的序列期间,每次将不同组的照明模块(20a..20n)连接到电压源(12)时。 然后,控制单元(102)根据在第一时刻检测到的测量信号(CS)来确定流过所有照明模块(20a..20n)的电流,并且确定流过各种照明模块(20a ... 20n)作为在瞬时序列期间检测到的测量信号(CS)的函数。

    • The invention relates to a tracking system (10) comprising at least one light source (12) which is designed to send a clear identification information (LID1) associated with the light source (12) using a light signal; and a mobile communication unit (ME1) having a camera (18), wherein the mobile communication unit (ME1) is designed to receive with the aid of its camera (18) the identification information (LID1) sent by the at least one light source (12); wherein the tracking system (10) further comprises at least one light sensor (20) having a camera (22); a central control unit (24) which is at least coupled to the at least one light sensor (20); wherein, upon receipt of the identification information (LID1), the mobile communication unit (ME1) is further designed to send an activation signal (LID1') to the central control unit (24) for activating a tracking operation, the activation signal (LID1') comprising correlated data with the received identification information (LID1); wherein the central control unit (24) is designed to determine on the basis of the activation signal (LID1') transmitted by the mobile communication unit (ME1), at which position the mobile communication unit (ME1) is arranged and which at least one light sensor (20) is arranged in such a manner relative to the position of the mobile communication unit (ME1) that the mobile communication unit (ME1) can be detected by the camera (22) of said light sensor. The central control unit (24) is furthermore designed to actuate the camera (22) of the at least one detected light sensor (20) for providing image information with teh aid of its camera (22) to the central control unit (24), in order to determine and identify a carrier of the mobile communication unit (ME1) at the determined position; wherein the central control unit (24) is further designed to actuate at least one light sensor (20) which is coupled to said central control unit for tracking the identified carrier of the mobile communication unit (ME1).
