An LED component is provided, with light emission in the green-to-near UV wavelength range. The light-emitting semiconductor die is encapsulated with one or more silicone compounds, including a hard outer shell, an interior gel or resilient layer, or both. The silicone material is stable over temperature and humidity ranges, and over exposure to ambient UV radiation. As a consequence, the LED component has an advantageously long lifetime, in which it is free of "yellowing" attenuation which would reduce the green-to-near UV light output. |
