Röhm’s PLEXIGLAS OPTICAL HT chosen for street and area lighting

Flat and compact design of the luminaire head with a relatively small area for the multi-lens array mean that the material is subjected to a high thermal load. PLEXIGLAS Optical HT withstands this load without compromising on optical qualities such as transparency, light transmittance, or UV and weather resistance.

With a certified UL RTI value of 105°C, the material is documented as being resistant to thermal aging, meaning that its high luminous efficacy can be maintained constantly over a very long period of time.

In the Tiara product family, directional multi-lens arrays are used which allow light properties remain constant over time.

High-power LEDs contribute to the very high luminous efficacy achieved at the output of the luminaire, reaching 170 lm/W.

The two-chamber design separates the optical chamber with the waterproof multi-lens array from the electrical equipment chamber, which can be opened without tools. This allows easier maintenance and replacement of components without damaging the sensitive lens.

In addition, the components or materials can be removed individually and returned to the circular economy. As a result, the PLEXIGLAS lens array can even be fully recycled to create new PMMA at the end of its service life.
