Best performing

products with LEDILoptics.Proper optics are usually just as important part of a good qualityproduct, than other key components like the LEDs and drivers.

Using suitable high quality optics, you achieve better beam control:

- More efficient lighting. Less LEDs, energy and money needed. - Reduction of glare caused by point source

and wide angles

- Possibilities to make more uniform light with different ambience and

cutoffs.

- Needed for illumination standards in many applications such as Street

lighting. - Freedom for design. (side emitting lenses, asymmetrical lenses, compact

size)-

Finished look and LED protection

Retrofit lampsLedil

has a series of different lenses

designed for retrofit lamps and differentlighting fixtures such as MR16 and MR11.

With our optics you can collect all the lightfrom the light source in example 120degbeam LED and make it a narrower moreintense beam such as 45deg.

Our lenses have typically a total efficiency ofaround 90%.

The lenses are designed to result a visuallypleasing beam. With nice color uniformityand smooth beam pattern reducing glare.

Search lights

Ledil is expert in making very narrow beam TIR lenses. With our IRIS series you can even reach a 4deg beam withsome LEDs.

Even over 80cd/lm peak values can be achieved. That

means around 150 times more intense peak intensity thanwith an LED alone.

Street lighting

LEDIL has an innovative STRADA street light lens series. Theselenses are optimized for may different LED packages and beamtypes. We have also newly released an asymmetrical STRADA-Tseries, that is designed to be used without tilting of the lamphead or overhang with arm.

Advantages of STRADA series: -Extremely uniform and well shaped beam

- Very good efficiency of over 90%.

-

With asymmetric Strada-T lenses, around 70% of the light is

on the street side. - Flexibility with mixing different Strada lens types with same

footprint to achieve wanted beam.
