Claim 0:
1. A lighting apparatus comprising:
a substrate;
a plurality of light emitting devices disposed on the substrate;
a resin layer disposed on the substrate and the plurality of light emitting devices, wherein the resin layer has a first side surface, a second side surface, a third side surface and a fourth side surface;
a first reflective layer disposed on the substrate;
a second reflective layer disposed on the resin layer; and
a third reflective layer disposed on the second side surface, the third side surface and the fourth side surface,
wherein the first side surface is between upper and lower surfaces of the resin layer,
wherein the first side surface has a length greater than a thickness of the resin layer in a first direction,
wherein the first side surface emits light having a highest luminous intensity among the first, second, third and fourth side surfaces of the resin layer by the light emitted from the plurality of light emitting devices, and
wherein the light emitted to the first side surface has a surface light in the form of a long line in the first direction, and
wherein an edge of the first reflective layer is spaced apart from an edge of the substrate to provide an upper open surface of the substrate between the third reflective layer disposed on the second side surface and the edge of the first reflective layer, and a portion of the resin layer contacts the upper open surface of the substrate.
