1. A light emitting apparatus, comprising:
a first light emitting device comprising:
a first substrate having a first upper surface and a first bottom surface;
a plurality of first LED chips disposed on the first upper surface and emitting a light penetrating the first substrate; and
a first wavelength conversion layer directly contacting the plurality of first LED chips and the first upper surface, and having a first shape in a cross-sectional view; and
a second wavelength conversion layer directly contacting first bottom surface, and having a second shape in the cross-sectional view, wherein the second shape is substantially the same as the first shape;
a second light emitting device separated from the first light emitting device, and comprising a second substrate and a plurality of second LEDs disposed on the second substrate; and
a support base connected to the first light emitting device by a first angle and connected to the second light emitting device by a second angle; and
a first support arranged between the support base and the first light emitting device.
