Bit Tech reports Shin-Etsu Chemical claims to have designed a new LED that offers longer-life and better brightness than currently available LEDs. The product used a new silicone encapsulating material that promises to ensure superior brightness through increased transparency and a lower refractive index than other encapsulating materials.
Sadly, they're not perfect: despite promised lifespans of thousands of hours, various issues - thermal cycling, gas permeation and others - conspire to send LEDs dark before their time.
Shin-Etsu's solution to the problem is a new silicone encapsulating material which it claims boosts reliability while ensuring superior brightness through increased transparency and a lower refractive index than other encapsulating materials.
Designed for use with high-brightness LEDs (HBLEDs) often used in case mods and home lighting systems, the new encapsulating material is claimed to have significantly reduced gas permeability over previous materials. The result, Shin-Etsu claims, is a reduction in corrosion of peripheral materials that can lead to reduced light output over time and even premature failure.
