BEGA hybrid optics

In order to maximise efficiency, BEGA is increasingly using hybrid optics in technical indoor and outdoor luminaires. Luminaires with these optical systems utilise the perfect interplay of precisely dimensioned reflectors with a pure aluminium finish and lenses made of ultra-clear silicone (Liquid Silicone Rubber, LSR). These hybrid optics offer a large number of advantages over conventional systems.

The hybrid optical systems are the perfect light transfer carriers for our LED technology. In all its optical systems, BEGA relies exclusively on durable materials that are subject to practically no wear.

In the search for good lighting, our silicone-based lenses have significant advantages over synthetic carbon-based lenses. Silicones are inorganic polymers which differ significantly from the organic polymers in thermoplastic synthetic materials (PC, PMMA and PMMI) in that they are resistant to ageing, even under extreme conditions like high temperatures and UV radiation. Thermoplastic synthetic materials, on the other hand, can suffer permanent damage through such external influences, but also simply through the operation of the LED and its blue content in the light spectrum and through the heat generated by the luminaire.

Together with the high-precision reflectors, the lenses ensure that practically all of the light from the LED module is captured by the hybrid optical system, relayed and used for optimum light distribution. This is what distinguishes it from conventional light deflection methods, in which only part of the light emitted is deflected or directed – while a large amount of light leaves the luminaire without optical light deflection.

All in all, this provides brilliant light distribution, a combination of reflected light from the reflectors and directional light from the silicone lenses.

Compared to other materials, the durability of the outstanding optical properties allows the consistent implementation of critical requirements for most innovative applications, even in changing ambient conditions.
