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.
