Round watercooled LED‑System

Water-cooled Light Emitting System OLM-046

The OLM-046 is a water-cooled hexagonal-shaped LED radiant source including a built-in controller unit and a power supply. This system contains 144 LED chips on board with a wavelength in the range 265-1050nm arranged under an array of parabolic reflectors that deliver the light at a narrow angle. For UVB/UVC LED Chips we offer the possibility to reduce the amount of chips down to 72 to match the costs. This system can be controlled directly from the radiant-unit or via a PC-program.



  • Light emitting circle with a diameter of 100 mm
  • A unique aluminum parabolic array of reflectors emitting the light at an angle of about 20°
  • New anti-reflection coating on the front window with a transmission value of about 97%
  • Innovative Heat sink with water channels that allowing operation at power losses up to 400W
  • Integrated electronic control that enables on/off switching directly from the radiator unit and automatic shutdown in case of overheating
  • PC program for external control of the system with a power level slider bar, temperature display, and last setting saving option
