LED news and insight from our technology editor Steve Bush, who has been messing with LED lighting for more years than he would care to remember.
Silicone Lenses for COB LEDs
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.
They are designed and made in Italy.
