Silicone Lenses for COB LEDs

   Khatod has introduced silicone lenses for CoB arrays, called SIO3.

The material has been chosen for its: sustained transparency over years, resistance to yellowing, UV-resistance, optical efficiency, lack of birefringence, temperature resistance (-40 to 150°C, 200°C peak), and flexible at low temperatures.

Designed for streetlights, depending on the LED used, they can comply with IESNA Standards: Type I, Type II, Type III, Type IV, Type V, short or medium light distribution.

These are large beasts: 111x110mm and around 35mm high.

Application is also expected in: parking areas, petrol stations, sport lighting, parks, gardens, pathways, canopies, shopping centres, offices, lifts, shop windows, and everywhere else…

“SIO3’s immersion-proof hydrophobic property makes these lenses particularly fitting for damp and wet environments. Indoor pools are a typical application,” said Khatod. “Also, their explosion-proof and shock-proof properties make SIO3 safe and reliable in hazardous environments such as mines. They do not shatter in the event of impact, flashover or vandalism.” – so no need for a sealing gasket or protective cover.

Beam Angles: 1 rotosymmetrical, 3 asymmetric, 1 axially symmetrical in x, y (rectangular spot).

They are designed and made in Italy.
