According to an embodiment, a lighting device comprises: a housing comprising a lower plate and a side plate; a substrate arranged on the lower plate; a light emitting module comprising light sources arranged on the substrate and spaced from each other; and a lens array unit comprising lenses arranged in correspondence to the light sources. The light sources have different magnitudes of quantity of light, and the sizes of the lenses are proportional to the magnitudes of light intensity of the corresponding light sources. Therefore, the lighting device improves brightness uniformity and color uniformity and prevents the lowering of a yield. |
