Lighting device

A lighting device comprising:

• a light wavelength conversion layer;
• a resin layer disposed on an upper surface of the light wavelength conversion layer;
• a light emitting device disposed on a first side surface of the resin layer,
• wherein the light wavelength conversion layer is disposed on a portion of a bottom surface of the resin layer,
• wherein the resin layer includes a second side surface opposite to the first side surface, and an upper surface opposite to the bottom surface,
• wherein a length of the resin layer in a first direction is greater than a bottom width of the resin layer in a second direction perpendicular to the first direction,
• wherein the first direction of the resin layer is a long axis direction of the resin layer and the second direction of the resin layer is a short axis direction of the resin layer,
• wherein the upper surface of the resin layer has a convex curved surface in a vertical direction orthogonal to the first and second directions with respect to the second direction, and
• wherein a maximum width of the convex upper surface of the resin layer in the second direction is the same as the bottom width of the resin layer.
