LensoFlex®2 is based upon the addition principle of photometric distribution. Each LED is associated with a specific PMMA lens that generates the complete photometric distribution of the luminaire. It is the number of LEDs in combination with the driving current that determines the intensity level of the light distribution. The proven LensoFlex®2 concept includes a glass protector to seal the LEDs and lenses into the luminaire body.
The LensoFlex®3 photometric engine, like LensoFlex®2, is based upon the addition principle of photometric distribution; each LED is associated with a specific lens that generates the complete photometric distribution of the luminaire. The main difference is the material used for the lenses.
LensoFlex®3 uses lenses made of mouldable and optical- grade silicon offering superior transparency and excellent photothermal stability. This withstands high driving currents and delivers maximise lumen output over time.
As silicon offers a higher thermal resistance compared to PMMA, temperature is not as critical for LensoFlex®3 engines. This offers two distinct advantages; LensoFlex®3 ensures an enhanced performance in warm climates or enables a high driving current to be used to increase the lumen output and a higher lm/kg ratio.
