Light emitting apparatus, back light unit and display apparatus

A back light unit comprising a light emitting apparatus, the light emitting apparatus comprising:

• a middle component comprising a light emitting device and having a recess and a protrusion at its two ends respectively;
• and
• a first end component and a second end component, one of the first and second end components having a recess, the other of the first and second end components having a protrusion,
• wherein the middle component can be connected with the first and the second end components respectively by corresponding protrusion and recess so that adjacent components can rotate relative to each other in a plane perpendicular to a light exit direction of the light emitting device.

A display apparatus comprising a back light unit, the back light unit comprising a light emitting apparatus, the light emitting apparatus comprising:

• a middle component comprising a light emitting device and having a recess and a protrusion at its two ends respectively;
• and
• a first end component and a second end component, one of the first and second end components having a recess, the other of the first and second end components having a protrusion,
• wherein the middle component can be connected with the first and the second end components respectively by corresponding protrusion and recess so that adjacent components can rotate relative to each other in a plane perpendicular to a light exit direction of the light emitting device.
