Definitions

  • composition of any LED illuminators includes a power source, 5 devices for dimming, sometimes emergency devices
  • All devices that are part of the illuminators, except for the LEDs have, as a rule, significantly lower reliability and service life (especially power supplies), which limits the duration of the illuminators as a whole .
  • the replacement of illuminators is associated with considerable laboriousness, requires special lifting means, etc., which increases operating costs.
  • the illuminators could be given a guarantee of 7 ... 10 years without much risk. In this case, the cost of the illuminator itself would be significantly lower.
  • the present invention describes a system of LED lighting, which includes a series of single illuminators in an unlimited number, which are powered by an alternating current main through a special 25 control unit that ensures the operation of N illuminators with stable
  • FIG. 1 shows an example of a lighting system circuit in which the illuminators are powered by a two-wire circuit, all illuminators are connected in parallel, and in the case of each illuminator there are only LEDs (sometimes with parallel switching on of PLED or a similar circuit for shunting the LEDs in case of failure).
  • a power supply circuit from a three-phase network is shown, including a three-phase rectifier 1, an active current source 2, connected in accordance with and in series with the rectifier 1 and the illuminators 3, which are connected in parallel and the LEDs are connected in series inside each illuminator.
  • Switch P6 selects the working - dimming mode.
  • Switch P2 initially sets the operating current of all illuminators connected to the system and can be set manually during installation of the system.
  • the PZ switch (there may be a variable resistor) determines the level of decrease in lighting during dimming, and the P 4 switch determines the level of illumination during emergency operation, while the P4 switch is activated
  • Converter 4 switch P5. The switch ⁇ automatically connects the converter 4 to the LEDs (through the current source 2, while the output voltage of the converter should approximately
  • the converter 4 is powered by the voltage of the battery 6 (12v) or others, and the signal D of its inclusion comes from the device 8, when the mains voltage disappears.
  • the charger 5 is powered by a rectified voltage and stops its operation when a signal E about the disappearance of the mains voltage.
  • An RCD can be included in the power supply circuit of LEDs (7). Wires 0 go to the illuminators, and the insulation in devices 5, 4 and in the output wires must withstand a voltage of 5 kV relative to the case, if the battery and these devices are outside an isolated power cabinet.
  • the switching device 8 of the system works as follows: when the circuit breaker (P) is turned on, the sensor detects the presence of mains voltage and the contactor is switched on with a time delay, supplying voltage to the entire circuit, contacts W open.
  • Signal D corresponds to the off state converter 4.
  • Signal E turns on the battery charge circuit. If the mains voltage fails, the signal D turns on the converter 4 and ⁇ , and the signal E turns off the charge circuit 5 of the battery 6, the contactor K opens. When the mains voltage appears, signal E appears and signal D disappears, the converter turns off, contacts W open and then contactor K is turned on, supplying the mains voltage to the entire circuit.
  • All devices except the battery are placed in an insulated plastic case with a lock with the input terminals of the network (3 wires) and 2 output wires in double insulation to the first illuminator or to several first illuminators and two wires to the battery.

  • This scheme allows you to quickly change the maximum power of the illuminators (within the margin of supply for LEDs) thereby compensating for the drop in illumination after years of operation.
  • This function can be programmed, which in conventional devices is only possible with wireless control, with the use of PLC modems in each illuminator or with additional wired connections. This scheme gives very serious savings in the purchase and operation.
  • each of them has protection in the form of a current source for a current slightly greater than the maximum working one.
  • an additional current source must be installed in each illuminator. It is desirable to have LEDs in this system with a small voltage spread. Since illuminators usually have a power of 30 ... 40 W, and the source of protection current in the illuminator must compensate for the voltage imbalance, which is usually less than 10%, the current source can be passive and very simple because low power is dissipated on it. If inside the illuminator one LED fails to short-circuit, then the imbalance will generally be insignificant 0.5 ... 1%, because there are more lOOLEDs in the illuminator.

Abstract

Le système d'éclairage à diodes électroluminescentes comprend un analyseur de courant secteur avec un circuit de rétention, un contacteur, un redresseur de tension réseau, un stabilisateur actif de courant et du groupe de luminaires montés en parallèle dans lesquels les diodes électroluminescentes sont branchées en séquence entre elles et avec la source de courant et le redresseur, un accumulateur et un chargeur allumé en réponse à un signal de l'analyseur de réseau. L'accumulateur est relié au transducteur de tension électrique qui est mis en marche au moyen du capteur de tension réseau. La sortie du transducteur via le premier interrupteur est branchée aux sorties du redresseur. Le stabilisateur de courant actif possède une entrée d'atténuation d'éclairage qui sert, au moyen du deuxième commutateur, de déterminer le courant de travail dans le circuit général du système. Au moyen de ce troisième commutateur on détermine le degré d'atténuation de lumière et au moyen du quatrième commutateur on détermine le niveau de courant pour l'éclairage d'urgence. Au moyen des cinquième et sixième interrupteurs on détermine le mode d fonctionnement de travail, l'éclairage atténué. Les luminaires comportent uniquement des diodes électroluminescentes. L'alimentation des luminaires en mode de travail, lors de l'atténuation d'éclairage et en éclairage d'urgence s'effectue via deux fils. On a prévu un montage préalable et une régulation du courant de travail des diodes électroluminescentes dans le système, du courant lors de l'atténuation d'éclairage et du courant des diodes électroluminescentes en mode d'urgence.
