IEL Science Achieves World's First Development of Silicone Lens for Multi-Beam Headlamps

[Asia Economy Reporter Hyunseok Yoo] IL Science announced on the 8th that it has succeeded in developing a silicone lens for automotive multi-beam headlamps applying dispensing technology for the first time in the world.

The lens for multi-beam headlamps, a core component of future advanced smart cars, requires ultra-precise design and mass production technology without errors. IL Science solved this with a silicone lens using its self-developed advanced dispensing method. The existing lens production method, injection molding, has limitations in mass production due to defects such as discoloration, deformation, and bubble formation during the solidification process of liquid silicone raw materials. IL Science’s dispensing method boasts a defect rate close to zero and does not require separate mold production, making it significantly advantageous in terms of cost and delivery time.

The silicone lens production facility located in the 5,300-pyeong Cheonan Smart Factory was designed and manufactured with IL Science’s own technology. The entire process from dispensing, molding, to demolding of liquid silicone lens raw materials is fully automated, requiring no separate production personnel.

Compared to existing plastic, acrylic, and glass lenses, silicone lenses have superior physical properties such as higher light efficiency, lighter weight, heat resistance, and no yellowing phenomenon, expanding their application not only in LED lighting but also in various fields such as automotive, medical devices, IT, displays, and smart farms.

In preparation for large-scale orders from global automakers following the successful development of multi-beam silicone lenses, the company plans to significantly expand its current monthly production capacity of 2.5 million units across four lines through line expansion. Additionally, once the Korea-Israel joint national project ‘Silicone UV (ultraviolet) curing’?currently in its final stages?is completed, production is expected to more than double.

IL Science is a small and medium-sized enterprise specializing in materials, parts, and equipment that succeeded in commercializing silicone lenses for LED lighting for the first time in the world in 2015. Last year, it was registered as a partner of a global automaker and is securing future growth engines in the automotive industry by replacing general lenses used in automotive electronics with silicone lenses.
