Lamp with LED as light source

The utility model discloses a lamp apparatus considering a light-emitting diode (LED) as the light source. The LED lamp apparatus comprises a LED end product, a light conversion material, a transparent element and an outer casing. The light conversion material is fixed on the surface of the transparent element, and the transparent element is fixed on the outer casing around the LED end product. The light conversion material is not contacted with the LED end product, which avoids the LED end product affecting the light conversion material as high temperature, thus the light conversion material has stable performance and is uneasy to age.
