| 发明名称 | LED light emitting apparatus having a light guiding device to achieve a uniform color distribution | ||
| 摘要 | An LED light emitting apparatus includes an LED light source, a light guiding device and an emitting window. The emitting window is covered with a phosphor layer. Light emitted directly from the LED light source is first transmitted to the light guiding device and then guided by the light guiding device towards the emitting window to evenly excite the phosphor layer. | ||

| 主权项 | 1. An LED (light emitting diode) light emitting apparatus comprising: an LED light source; a light guiding device and an emitting window covered with a phosphor layer; wherein light emitted directly from the LED light source is first transmitted to the light guiding device and then guided by the light guiding device to move uniformly towards the emitting window to evenly excite the phosphor layer to generate a light having a color different from that of the light emitted directly from the LED light source; and wherein the LED light source directly contacts the surface of the emitting window and extends through the phosphor layer to face the light guiding device, and is surrounded by the phosphor layer. | ||
