System for street lighting "Integral"

System for street lighting "Integral" refers to energy-saving devices system and designed for high-frequency feeding of street lighting sodium lamps energization and control using exclusive electronic ballast apparatus (by the power -70, 100, 250, 400 W ). An overall controller located in the main cabinet realizes the remote control.

• Energy saving - 20 to 60%
  The power consumption and light flow of the "Integral" system is independent of the voltage fluctuatio. Thanks to high-frequency feeding the light flow of the lamps increasing by 20% as compared with the main supply current at 50 Hz.
  The lamp is fed by the high-frequency current in range of 50 - 100 kHz.
  Electronic ballast for "Integral" system is just used active power (cos j=1).
• The remote control
  The overall controller realizes the remote control. Electronic ballast is performed tree commands:
  - switch the lamp on
  - switch the lamp off
  - power dimming
• The low starting current
  The starting current is below the rated currents.
• The development of lighting system
  The active and reactive power is down therefore 'Integrall" system needs the power lead with the lesser section.
• Increase of the lamp life time
  Thanks to high-frequency feeding the lamps lifetime are increasing, saving high level of the light flow. After 10000 hours, the lamp saves 90 % of light flow.
• Safety and ease of maintenance.
  A short circuit between the lamp cables will not lead to overheating or the feeding cable. All breakdown linked to a temporary or permanent fault on the lamp circuit is suppressed, because there is no electrical continuity. Detection of lamps at end of life enables the maintenance team to easily identify lamps to be replaced. After 2 or 3 extinction and restarting cycles automatically cuts the power supply to worn-out lamps. Electronic ballast automatically turns off the lamp to preserve it as soon as the voltage goes out.
• Reduce of deleterious effect to surroundings
  There is no noise and stroboscopic effect by using heigh frequency power fed to the lamp.
