Gaggione achieves breakthrough solid-state lighting component design using optical-grade Dow Corning® MS-1002 moldable silicone

The Challenge
Gaggione S.A.S., an innovative designer and manufacturer of advanced optical components, has earned a reputation for diligently evolving and expanding its LEDnLIGHT® family of optical collimators to address the latest performance demands for solid-state lighting. Occasionally, it has found the demands of the market can challenge the limits of conventional optical materials. This was the case when Gaggione sought to develop two unique 32 mm and 67 mm circular collimators for chip-on-board (COB) and other high-brightness LED architectures for solid-state lighting applications.

One of the key challenges Gaggione confronted was that its collimator design incorporated a negative draft angle as well as variable wall thicknesses. Both of these features are difficult to fabricate using conventional thermoplastics or glass. In addition, targeted LED lighting applications demanded that the material deliver reliable mechanical and optical performance despite exposure to high lumen densities, outdoor ultraviolet (UV) light, external temperatures cycling between -40 °C and 125 °C, and internal module temperatures reaching as high as 110 °C.

On top of all that, Gaggione has constantly sought material technologies that enable increased efficiency for its products through simple, cost-effective manufacture and assembly that lead to lower total cost of ownership for its customers.

Find out how Gaggione’s patented new collimator design was possible with the help of Dow Corning’s technical expertise and their advanced Moldable Optical Silicones materials. Read the full case study.
