A lighting device disclosed in an embodiment of the invention includes a substrate; a plurality of light sources spaced apart from each other at predetermined intervals on the substrate; a resin layer disposed on the substrate; a phosphor layer disposed on the resin layer and having a pattern layer including a concave portion and a convex portion formed on a surface facing the resin layer; and a diffusion layer disposed between the resin layer and the phosphor layer, wherein a thickness of the diffusion layer may be 10% or more and less than 50% of the maximum thickness of the phosphor layer.

When light is off, a transparent appearance is obtained, while when the light is on, light is seen through a transparent spot. The present invention includes a light source portion and a reflective portion. The light source portion emits light. The light source portion is disposed at a position shifted with respect to an emitting direction of emitted light from the reflective portion. The reflective portion reflects the light from the light source portion and emits it in a predetermined direction. The reflective portion is constituted by a transparent member with a refractive index at least in a visible light area larger than 1. As a result, in the present invention, the transparent appearance is obtained when the light is off, while the light is seen through the transparent spot when the light is on.

A phosphor composition may include first and second phosphors configured to emit light of a first and a second unsaturated color, respectively. The first unsaturated color may be associated with a first position in a CIE standard color chart adjacent to and above a position of a selected target color of the phosphor composition in the CIE standard color chart. The second unsaturated color may be associated with a second position in a CIE chromaticity diagram adjacent to and below the position of the selected target color of the phosphor composition in the CIE chromaticity diagram. Thereby, the position of the selected target color of the phosphor composition in the CIE chromaticity diagram may be located in an area defined by corner positions R=(cx; cy) given by R1=(0.645; 0.335), R2=(0.665; 0.335), R3=(0.735; 0.265), and R4=(0.721; 0.259).
