LRB 20 Lighthouse Revolving  LRB-20 LIGHTHOUSE REVOLVING BEACON



  • FEATURES: , The LRB-20 is a versatile stand alone high range gearless revolving LED beacon for Lighthouse application.
  • LED PANELS : The octagonal shaped rotating assembly is made of alumunium plates. Upto 8 LED panels can be fitted on the alumunium plates to suit the required light characters, and with the selectable rotation period, variety of light characters and light ranges can be achieved.
  • LED PANELS DRIVE :The LED panel assembly is rotated by a low power microprocessor controlled gearless system. the drive systems are duplicated. If one drive fails, the standby drive switches ON automatically. Also the standby drive can manually be switch-ON from the front control panel.
  • LED CONTROLLER:The LED controller is microprocessor based unit incorporating all the controls. Also it has solar charge regulator for the battery protection from over / under charge. The beacon switches ON/OFF automatically.
  • LIGHT CHARACTERS/ROTATION SPEED SETTING : The speeds are pre-set for 5, 10, 12, 15, 20, 25, 30, 40, 50, 60 seconds per revolution. By selecting the no. of LED panels and setting required speed can create all the desired light characters. (other speeds can be set on request.)
  • MONITORING : (OPTIONAL):The system is suitable for remotely monitoring of all the necessary functions of the beacon by using GPS and GSM system.
  • CONTROL PANEL :The control panel is fitted on the front part of the beacon body containing all the manual controls and indication lamps etc.
  • POWER SUPPLY :The beacon can be supplied with solar supply system or AC/DC unit with battery standby for mains supply system.
