1. A lighting device comprising:
- a case including;
a bottom plate;
walls extending from ends of the bottom plate; and
louvers coupled to and inclined from respective ones of the walls;
a light emitter disposed over the bottom plate; and
a diffuser plate spaced apart from the light emitter and disposed between the walls, wherein the louvers are oriented at an obtuse angle relative to the diffuser plate, wherein the light emitter includes an LED, and wherein;
the louvers are located at positions which lie outside a first area, andthe first area is inside of the walls and overlaps the light emitter, andwherein at least one of the walls comprises a coupling recess and the diffuser plate is coupled to the coupling recess.
