Lighting module and lighting device comprising same

A lighting module comprising:

• a substrate;
• a plurality of light emitting devices disposed on the substrate, each of the light emitting devices includes an LED chip that emits light from a plurality of side surfaces and from an upper surface;
• a resin layer disposed on the substrate and the plurality of light emitting devices;
• a phosphor layer disposed on an upper surface and side surfaces of the resin layer, the phosphor layer including a top portion disposed on the upper surface of the resin layer and a plurality of side portions on the side surfaces of the resin layer such that the resin layer is surrounded by the plurality of side portions, wherein each of the side portions separately contacts an upper surface of the substrate;
• and
• a plurality of recess portions overlapping each of the plurality of light emitting devices in a vertical direction, wherein a total number of the plurality of recess portions is same as a total number of the light emitting devices, and an edge between two side surfaces of the recess portion corresponds to an edge between two side surfaces of the light emitting device that vertically overlap the recess portion,
• wherein the resin layer is disposed on upper side and outer side of each of the plurality of light emitting devices,
• wherein an upper surface area of each separate one of the plurality of recess portions is within a range of 101% to 150% of an upper surface area of a separate corresponding one of the plurality of light emitting devices that is vertically overlapped by the recess portion,
• wherein each of the plurality of recess portions is formed to be concave toward a corresponding one of the plurality of light emitting devices on the upper surface of the resin layer, and includes an inclined side surface which is lower than the upper surface of the resin layer,
• wherein a pitch between two of the light emitting devices is equal to or greater than a thickness of the resin layer in the vertical direction,
• wherein a shortest distance between each of the plurality of light emitting devices and a corresponding one of the plurality of recess portions is within a range of 3 to 5 times a thickness of the light emitting device in the vertical direction, and
• wherein a linear distance from a lower surface of the substrate to an upper surface of the phosphor layer is within a range of 3 mm to 5 mm.
