Glass tubing for LED signal lights
Glass is the only optionAs one of the first companies in the world to focus solely on LED technology, Obelux has built a reputation for quality. It is one of the only major players in the industry to secure its luminous devices with glass rather than plastic, which is cheaper and lighter.
So why did they choose glass? Tapio Kallonen, Director of Sales and Marketing at the Helsinki-based company, explains the innovation was hardly a choice. “We decided at the very beginning of our journey that glass was the only option. The costs would be worth the result.”
His customers agree. “Our products are on skyscrapers, wind turbines, bridges, even out at sea,” says Tapio. “These places are hard to reach, very hard to clean, and very hard to service with maintenance or repair.”
It’s all about the opticsAviation signal lights are designed to last upwards of 20 years, and must offer a consistency of performance that satisfies strict regulations from various industries and authorities. Devices with plastic covers absorb a fraction more light than glass, producing slightly less luminous output. “It’s all about the optics,” says Tapio. “We get more light through glass.”
DURAN® borosilicate glass meets these optical requirements, as well as protecting the LED lights perfectly. “Let’s imagine a typical example, like an offshore wind farm. You’ve got salt spray, cold wind, and many other factors which affect a device. After two or three years in these conditions, a plastic cover is damaged on a completely different scale compared to one made from DURAN® borosilicate glass. By then, the plastic cover may no longer be compliant with industrial guidelines. Yet after 10, 15, even 20 years, that glass beacon shines as brightly as on day one.”
