K 2010. LEDs Shine Brightly for Longer

Essen, October 27, 2010

Reflector sockets have a significant influence on the quality of LEDs. The whiter the reflector socket, the higher the reflectivity and the greater the luminous efficacy. Sockets made of VESTAMID® HTplus, a polyphthalamide PA10T developed by Essen, Germany-based Evonik Industries, remain pure white for a longer period , so the LED continues to shine brightly, generating a consistently high light yield. This gives the LEDs a much longer life. In addition, VESTAMID® HTplus is particularly environmentally friendly because 50% of the polymer is based on renewable raw materials.

Conventional reflector sockets turn yellow over time due to the effect of light and heat. As a consequence, the reflectivity and the luminous efficacy are continuously diminished until the light-emitting diode ultimately needs to be replaced. This is not the case for sockets made of VESTAMID® HTplus on account of the very bright inherent color of the material coupled with its outstanding UV stability. Thanks to its low water absorption, VESTAMID® HTplus also boasts better dimensional stability, which makes it easier to process and makes it suitable for use in particularly small LEDs. The miniaturization trend is also supported by the excellent adhesion to metal and silicon.
