SIR50 Silicone Internal Reflection Lenses are available both with or without Khatod holder. If needed the LED holder can be purchased directly from Bender-Wirth.
The holder with connector by Bender-Wirth is optional, available only on request.
Differentiating Features
  • Exclusive optical techniques: all the exit surfaces of SIR LENSES include rotated microlenses arrays, or microlenses arrays alternated with matt surfaces. This avoids any aesthetical issue in light distribution, such as variations of the color temperature. Ensure a perfect control of the light flux
  • Unique silicone processing method: Khatod customized the cold-injection process by implementing innovative technologies never used before in the transformation phase of silicone while it is injected
  • Lens fixing to the PCB: SIR LENSES are available with their proper holder. It enables a direct mounting onto the PCB, ensures a perfect fastening, simplifies the assembly in the final application. The holder is a mechanical assembly made up of two parts:
    • bottom: fasten it to the PCB with 2 screws or a sticker, then place the lens
    • top: a ring nut matching the bottom fixes the lens housing and completes the holder assembly
