1. A lighting module comprising:
a substrate;
a plurality of light emitting devices disposed on an upper surface of the substrate;
a resin layer disposed on the plurality of light emitting devices; and
a reflective member disposed around the plurality of light emitting devices and disposed on the upper surface of the substrate,
wherein the reflective member includes a plurality of reflective units including a first reflective region and a second reflective region facing the first reflective region,
wherein at least one of the plurality of reflective units has a first angle between a straight line connecting an uppermost point of the first reflective region and a first point where the substrate and the first reflective region are in contact with each other and a tangent line of the substrate at the first point, and has a second angle between a straight line connecting an uppermost point of the second reflective region and a second point where the substrate and the second reflective region are in contact with each other and a tangent line of the substrate at the second point,
wherein at least one of the plurality of reflective units has the first angle and the second angle different from each other,
wherein a part of the reflective member is disposed between the plurality of light emitting devices, respectively, and
wherein the plurality of light emitting devices overlap the substrate and the resin layer in a vertical direction,
wherein the resin layer has an upper surface that extends in a horizontal direction and vertically overlaps each of the plurality of light emitting devices and the reflective member,
part of the resin layer is provided, in the vertical direction, between the upper surface of the resin layer and each of the light emitting devices,
part of the resin layer is provided, in the vertical direction, between the upper surface of the resin layer and an uppermost point of the reflective member which is vertically closer to the upper surface of the resin layer than an upper surface of the light emitting device, and
wherein a height of the reflective member from a bottom surface of the reflective member to the uppermost point of the reflective member is greater than a thickness of each of the plurality of light emitting devices and is smaller than a height of the resin layer from a bottom surface of the resin layer to the upper surface of the resin layer,
wherein the lighting module further comprising:
a phosphor layer having an upper portion disposed on the upper surface of the resin layer, and the phosphor layer includes first and second side portions disposed on opposite sides of each other and a protrusion portion, each of the first and second side portions of the phosphor layer is disposed on opposite sides of the resin layer and is joined with the upper portion, the upper portion extending in the horizontal direction to vertically overlap each of the plurality of light emitting device and the reflective member, the protrusion portion extending in the vertical direction from the upper portion, each of the first and second side portions of the phosphor layer is in contact with outer surfaces of an outermost reflective units of the reflective member, and lower ends of the first and second side portions of the phosphor layer are adhered to an upper surface of the substrate, wherein the phosphor layer is made of a different material than the resin layer, and the phosphor layer is a continuous layer that includes the first and second side portions, the upper portion and the protrusion portion,
a light shielding portion disposed on the upper surface of the resin layer such that the light shielding portion is disposed between the phosphor layer and the resin layer and such that the light shielding portion is overlapping the upper surface of each of the light emitting devices in the vertical direction, and
the protrusion portion of the phosphor layer overlaps the light shielding portion in the vertical direction and further protrudes in the vertical direction from the upper surface of the phosphor layer, and the protrusion portion overlaps the light emitting devices in the vertical direction such that the light shielding portion is between the protrusion portion and the light emitting devices in the vertical direction.
