When enclosed together with LEDs during luminaire assembly, incompatible VOCs may degrade the light output performance, change the colour points and reduce the life span of LEDs. Incompatibility comes in varying degrees: some chemical materials are critical when in direct contact with LEDs but are fine when enclosed without being in ­contact with the LED (indirect contact - also referred to as proximity). Some materials, such as adhesives and sealants, may be critical during the curing process, but less so when fully cured. Cree® has defined a testing methodology to evaluate chemical compatibility. Many Henkel products meet the requirements set forth by Cree® and we are committed to continue systematically testing our products. This will help you select the right adhesive and sealant for your application and be assured that incompatibility will not become an issue for you. Chemical Compatibility to LEDs VOC Entry and Failure Mechanism Silicone Lens 1. LEDs are typically protected by an ultra clear silicone lens LED Chip VOC Enclosure, e.g. ­luminaire housing 2. When enclosed during luminaire assembly, some volatile organic compounds (VOCs) may diffuse into silicone lens 3. Heat and photon energy discolor VOCs and reduce lumen output or may cause failure of LED Be Light Years Ahead | 19 Performance testing Comparison of Henkel LED Compatible Products on Cree® Test Boards Photo 1: LEDs utilising Henkel compatible products Photo 2: LEDs without Henkel compatible products Did You Know? In some cases discoloration of LEDs by incompatible VOCs may be reversible when the enclosure around the LED is removed.
