摘要: A wavelength converting element (104), typically for a LED (101), is provided, comprising luminescent particles (105) dispersed in a matrix (106) comprising crosslinked polysiloxane. Crosslinked polysiloxanes are temperature stable, typically up to temperatures above 300° C., meaning that they are stable under normal operating conditions of light emitting diodes. Further, crosslinked polysiloxanes are stable towards exposure to light, meaning that they will not degrade/discolor as a consequence of high intensity light exposure. The polymeric wavelength converter can easily be shaped in different forms. This may lead to better outcoupling of the light from a LED-converter system.
摘要翻译: 提供通常用于LED(101)的波长转换元件(104),其包括分散在包含交联聚硅氧烷的基体(106)中的发光颗粒(105)。 交联聚硅氧烷是温度稳定的,通常高达300℃以上的温度,这意味着它们在发光二极管的正常工作条件下是稳定的。 此外,交联聚硅氧烷对于暴露于光是稳定的,这意味着它们不会由于高强度光照而降解/变色。 聚合物波长转换器可以容易地以不同的形式成型。 这可能导致来自LED转换器系统的光的更好的耦合。
