Dow has published a new white paper, “Blue Light Photothermal Aging of Thermoplastic and Silicone Lens Clusters,” with insights for luminaire designers, optical engineers, and LED module manufacturers. Through comparative testing under heat and blue-light irradiance, silicone optics demonstrated superior stability under high photothermal loads, while the thermoplastic optics were prone to discoloration, and, in some cases, catastrophic thermal runaway.
Dow has published a case study that explains how its award-winning SILASTIC™ MS-4007 Moldable Silicone enabled award-winning emergency vehicle lighting. Dow’s two-part, heat-cured silicone resin is lighter than glass, resists yellowing better than plastic, and can withstand high heat and moisture while providing excellent light transmittance for optical clarity.
Dow is sharing a technical presentation about how its SILASTIC™ Moldable Optical Silicones are enabling advanced automotive lighting. For example, adaptive driving beam (ADB) technologies use a high-power LED matrix with a silicone primary lens. Rear lamps and indicators use linear LEDs with a silicone coupler and light guide. Dow’s technical presentation also covers material, mechanical, and optical properties.
