N-series Collimator Led lens

Led_1
N series Led lenses have been developed for Cree XT-E Leds and similar ones (diode dimension untill 1,8 mm).

Thanks to the cooperation with the University of Padua, IODA has developed a new type of “collimator secondary led light lenses”. These lenses for lighting LED are not reflecting parabolas but are penetrated by the light emitted and “drive” the light beam by adjusting the amplitude of the angle of emission ensuring maximum efficiency.

The usage of these collimator LED lenses allow you:
- to reach an angular distribution with high performance. (90% of the emitted light is directed to the right direction),
- to obtain extreme compact lens solutions,
- to have a beam light without any color distorsion,
- to work in a wide operating temperature range (among -40°c~ and+120°c)
- to be stable over time and resistant to U.V. rays.

The N-series lenses includes the following models:
N-11 with angle distribution = +/- 11 degrees.
N-20 with angle distribution = +/- 20 degrees.
N-30 with angle distribution = +/- 30 degrees.
N-40 with angle distribution = +/- 40 degrees.

The plano-convex lenses are developed with a special aspherical convex design, these lenses are created thanks to free form production line and can faithfully reproduce the design of the lens.The base diameter of the lenses is 14mm.

The innovative lens shape with the new optical materials gives high performance and efficiency to your led light source, allowing you to use led light in new ways.

Material.

REVO-01 is made of Polyurethane monomers material with excellent mechanical, thermal and chemical resistance properties.

This monomer is usually used for casting plastic lenses for eyewear, sunglasses and other plastic products requiring high abrasion resistance and high quality optical properties, showing better mechanical and optical characteristics when compared with lenses made by the procedure of injection molding with thermoplastic resins. — REVO-01 trademark of IODA s.r.l. –

The lenses could be produced also in glass BK7 for special applications when they must work with high temperature or in aggressive atmosphere.

LK series lenses thanks to the outer diameter of only 20mm allow to create lighting solutions extremely compact.
Thanks to the special design of the base of the lens, it is simple to use them with a fixing flange or pasting directly into the base.

Lens Module

Thanks to our particular production system, IODA can create “multi led Lenses” on customer’s request.
IODA can offer the possibility to create unique solutions for the customer, in an easy and fast way. Finally the secondary lenses will be a resource to complete and make unique your work!
