    摘要： One or more LED dice are mounted on a support structure. The support structure may be a submount with the LED dice already electrically connected to leads on the submount. A mold has indentations in it corresponding to the positions of the LED dice on the support structure. The indentations are filled with a liquid optically transparent material, such as silicone, which when cured forms a lens material. The shape of the indentations will be the shape of the lens. The mold and the LED dice/support structure are brought together so that each LED die resides within the liquid silicone in an associated indentation. The mold is then heated to cure (harden) the silicone. The mold and the support structure are then separated, leaving a complete silicone lens over each LED die. This over molding process may be repeated with different molds to create concentric shells of lenses. Each concentric lens may have a different property, such as containing a phosphor.

    摘要： In one embodiment, sub-micron size granules of TiO2, ZrO2, or other white colored non-phosphor inert granules are mixed with a silicone encapsulant and applied over an LED. In one experiment, the granules increased the light output of a GaN LED more than 5% when the inert material was between about 2.5-5% by weight of the encapsulant. Generally, a percentage of the inert material greater than 5% begins to reduce the light output. If the LED has a yellowish YAG phosphor coating, the white granules in the encapsulant make the LED appear whiter when the LED is in an off state, which is a more pleasing color when the LED is used as a white light flash in small cameras. The addition of the granules also reduces the variation of color temperature over the view angle and position over the LED, which is important for a camera flash and projection applications.

    摘要翻译： 在一个实施方案中，将TiO 2，ZrO 2或其它白色非荧光剂惰性颗粒的亚微米尺寸颗粒与硅氧烷密封剂混合并涂覆在LED上。 在一个实验中，当惰性材料占密封剂的约2.5-5重量％时，颗粒将GaN LED的光输出增加超过5％。 通常，大于5％的惰性材料的百分比开始降低光输出。 如果LED具有黄色的YAG荧光粉涂层，则当LED处于关闭状态时，密封剂中的白色颗粒使得LED显得更白，当LED用作小型相机中的白光闪光时，这是更令人愉快的颜色。 颗粒的添加还减少了在LED上的视角和位置上的色温变化，这对于相机闪光和投影应用是重要的。
