High Current LED Lenses

Standard Lens Options

Smart Vision Lights offers a variety of standard lens options.

Lenses for high current LEDs

These lens options provide a range of illumination angles, working distances, and patterns.

Example: Lens options on LXE Series Lights:

Standard LED lenses, like above, are typically plastic. Smart Vision Lights also has silicone lens technology. Silicone lenses allow custom beam-shaping and light guides. Additionally, this technology can be used with UV wavelengths where conventional lens technology fails.

Silicone Optics Lenses

Optical-grade silicone offer an exciting alternative for lighting manufacturers. Unlike glass and plastics, silicone:

  • Does not age like polycarb, vinyl, or acrylic
  • Does not yellow with time
  • Does not craze due to heat, exhibiting no material
  • Changes in temperature range from –115°C to 200°C
  • Does not react to UV light
  • Does not react with most harsh chemicals
  • Offers high transmission across a broad spectrum, with 95% transmission or better from 365 nm (UV) to 2000 nm (NIR)

While silicone offers these material benefits compared to plastic molded lenses, it also offers advanced manufacturing benefits. For example:

  • Silicone is very robust. It maintains its optical function over its lifetime and is resilient to changes in the environment.
  • Optical-grade silicone is capable of holding fine structure patterns and can possess reverse curves in a single molding tool; this cannot be done in conventional plastics.
  • Silicone’s ability to form complex optical elements using multiple shots in a single injection mold allows for a lower total cost solution for complex, multi-part optics

The lens technology described above, sets the beam-shape for the light. Adding frosting to the lens, or a diffuser, modifies the beam-shape to scatter the light and make a softer diffused illumination. Diffusion also scatters the beam and makes a wider footprint.

A focused, but non-diffused beam, provides direct, on-axis illumination. This is the brightest illumination type and is desirable in some cases, but can enhance glare and reflections making the light source harsher.

Example of a Diffused Light Source:
