LLK Led Lenses KIT

Develop your optical lens system by yourself

IODA produces a set of lenses for LED lighting, called LLK (Led Lenses Kit), that allows you to test and evaluate the variation of the opening angle of the light emitted by one or more lenses at different distances.

Often we are asked to produce optical systems to manage the light emitted by a LED or a COB, since the market cannot offer the exact solution for the specific application.

Each lens of the LLK kit is provided with an outer ring that allow you to adjust the distance of the lens from the base and the superimposition of more lenses.

The lenses included in the kit LLK are produced by IODA srl for the lighting market and may also be requested individually with or without the outer support ring (ring kit).

Convention is to provide values of angular opening with the axis perpendicular to the plane in which the base of the LED, so a value of +/- 45 ° means that the angle of the cone of light emitted by the optical system has the absolute angle 90 °.
