Abstract
An embodiment 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 so as to correspond 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 quantity of light of the corresponding light sources.

A lighting device comprising:
- a housing including a lower plate and a side plate;
- a light-emitting module including a substrate disposed on the lower plate and light sources disposed on the substrate;
- and
- a lens array unit including lenses arranged corresponding to the light sources,
- wherein sizes of the lenses are proportional to a quantity of light from the light sources,
- the quantity of light from the light sources decreases moving away from a center line of the housing in a direction perpendicular to the center line of the housing,
- wherein sizes of the lenses decrease moving away from the center line of the housing in the direction perpendicular to the center line of the housing, and
- wherein a separation distance between adjacent light sources and a separation distance between adjacent lenses decrease moving away from the center line of the housing in the direction perpendicular to the center line of the housing.
