Light emitting diode device and light emitting apparatus

A light emitting diode (LED) device, comprising:

• an epitaxial layered structure that includes a first semiconductor layer, a light emitting layer and a second semiconductor layer sequentially disposed in such order;
• a first electrode that is disposed on said epitaxial layered structure and that is electrically connected to said first semiconductor layer;
• and
• a second electrode that is disposed on said epitaxial layered structure, that is electrically connected to said second semiconductor layer, and that includes a body portion and at least one extending portion connected to said body portion and extending in a direction away from said body portion, said extending portion including at least one curved section and a connecting section that connects said body portion and said curved section,
• wherein a projection of said curved section on said epitaxial layered structure includes a first curved side and a second curved side that are opposite to each other and that are curved in an identical direction, said first curved side having a first imaginary center of curvature and a first radius of curvature, said second curved side having a second imaginary center of curvature and a second radius of curvature that is larger than the first radius of curvature, and
• wherein a projection of said connecting section on said epitaxial layered structure includes:
• a first connecting side that is connected to said first curved side and that has a third radius of curvature, and
• a second connecting side that is connected to said second curved side and that has a fourth radius of curvature;
• and
• said first connecting side and said second connecting side are curved in opposite directions, and
• the third radius of curvature and the fourth radius of curvature are smaller than the first radius of curvature.
