Definitions

  • the invention relates to lighting engineering and can be used in the manufacture and operation of LED lighting devices operating in an unstable electric power network.
  • the mains voltage from which the LEDs are powered does not have a stable value and, in general, can vary between + 10% - 15% of the nominal value or more. Therefore, if you change the number of LEDs included in the network synchronously with the change in the mains voltage and simultaneously change the current in the LED circuit by the same percentage in the opposite direction, then the luminous flux of this light source will be unchanged. Since the voltage at switchable diodes can only be changed discretely (minimum by the magnitude of the voltage on one LED), then the magnitude of the current will change discretely in the same percentage. If a current source is connected in series with the LEDs, then within the voltage between the terminals of the LED, the current can be stabilized, and the power of the current source must be greater than the power dissipated by the LED.
  • the PLC modem 7 also controls the current source 6 and is connected to the mains.
  • the voltage corresponding to the current value of the mains voltage with a current corresponding to this voltage arrives at the top of the pole.
  • the magnitude of the current of the current source 6 corresponds to the position of the switch ⁇ réelle réelle, the position of which in turn depends on the input voltage level, which controls the switch ⁇ 1 réelle through the voltage sensor 4.
  • the voltage and current sensor change on the resistor (Fig. 2) 4 switches the number of diodes with the switch ⁇ according to the position of the switch ⁇ 1 réelle (in the base of the column).
  • the LED board in the illuminator
  • the reliability of such a illuminator is actually determined by the reliability of the LEDs. Subject to certain rules, such a illuminator can be warranted for more than 10 years, and the actual operating time of LEDs can be more than 100,000 hours.
  • a varistor in a 2-wire line connecting the column base to the illuminator, and to include a passive current source with a current value greater than the maximum possible LED current in the operating mode in the common current circuit.

Abstract

L'invention concerne le domaine des équipements d'éclairage. Le résultat technique consiste à augmenter la fiabilité et la durée de vie. Le dispositif comprend deux parties, la première étant constituée par : un redresseur, un dispositif de compensation des pulsations, un capteur de tension, un comparateur, une commande de commutateur de courant, un commutateur de courant (111). une source de courant passive, un dispositif de commande PLC. Deuxième partie: un premier groupe de diodes électroluminescentes, des groupes commutés de diodes électroluminescentes, une résistance de mesure, un capteur de courant, un commutateur de commande du nombre de diodes électroluminescentes. Dans la première partie, le redresseur est relié en série avec le dispositif de compensation des pulsations par une source de courant passive faible puissance, et le signal PLC possède une commande prioritaire de la source de courant et reçoit le signal de commande depuis le centre de commande via les câbles du réseau. Le luminaire est alimenté par une tension non stabilisée via une ligne à deux fils à courants fixes en fonction du signal PLC et du premier commutateur de courant. Dans la deuxième partie la résistance de mesure est reliée à un capteur de courant et comparateur qui commande le deuxième commutateur de courant commutant le nombre de diodes électroluminescentes branchées sur le circuit en fonction du niveau de courant dans la ligne à deux fils de manière synchrone avec le premier commutateur de courant. On a branché dans le circuit de la ligne à deux fils, en série avec la résistance de mesure, un groupe principal de diodes électroluminescentes et plusieurs groupes de diodes électroluminescentes branchés sur ce circuit en fonction du courant sur la ligne à deux fils qui dépend du niveau de tension entrant dans le réseau.
