High transparency silicone rubber moulded components can be used as optical components in various high power lighting systems. By using high transparent silicone rubber. LED lighting is already one of the most energy-efficient developed technologies on the market due to the durable and long lasting performance compared to conventional lighting technologies.
LED lights have been hailed as the future of interior and exterior lighting as they use very little energy, have an increased lifespan and, unlike regular energy-saving bulbs, they produce an instantly bright light when switched on.
however, although more energy efficient, LED’s generate high heat, meaning thermal management is critical to allow LED systems to operate at full capacity. Materials that make up the lighting systems need to be able to withstand high temperatures and usage to prevent downtime and repair costs due to failure.
Global LED light guide silicone rubber market accounted for $XX Billion in 2022 and is anticipated to reach $XX Billion by 2030, registering a CAGR of XX% from 2023 to 2030.
Wacker Presents New Silicone Rubber Grades for Encapsulating LEDs.Wacker, the Munich-based chemical company, will unveil two new encapsulation compounds for light-emitting diodes (LED) at the 20th International Trade Fair for Plastics and Rubber K in Düsseldorf, Germany.
The encapsulants Lumisil 740 and Lumisil770 cure to form highly transparent silicone elastomers. Both silicones withstand exceptionally high operating temperatures and strong light radiation without yellowing or becoming brittle.
They are thus ideal for encapsulating high-performance LEDs. K 2016 will take place from October 19 to 26, 2016.They cure at room temperature via a platinum-catalyzed addition reaction.
The cured rubber grades have a refractive index of 1.41, which is typical of polydimethylsiloxanes. The two products thus belong to the group of normal refractive index (NRI) encapsulants. They effectively protect the sensitive LED semiconductor chip against environmental influences. They can additionally serve as carriers for luminescent dyes, which can selectively influence the color of the light emitted by the LED.
