1. A lighting device comprising:
- a first lighting module having first and second louvers;
a second lighting module having third and fourth louvers;
a first diffuser over the first lighting module; and
a second diffuser over the second lighting module, wherein the first and second lighting modules each include a plurality of light emitting diodes, wherein the first and second lighting modules each include a first slanted side surface and a second slanted side surface, and wherein;
the first diffuser is coupled between the first and second slanted side surfaces of the first lighting module,the second diffuser is coupled between the first and second slanted side surfaces of the second lighting module,the first and second louvers are coupled to respective edges of the first and second slanted side surfaces of the first lighting module and extend at an obtuse angle relative to the first diffuser, andthe third and fourth louvers are coupled to respective edges of the first and second slanted side surfaces of the second lighting module and extend at an obtuse angle relative to the second diffuser.

11. A lighting device comprising:
-
a case comprising; a bottom plate; walls extending from ends of the bottom plate; and louvers coupled to and inclined from respective edges of the walls; a light emitter coupled to the bottom plate; a diffuser plate spaced apart from the light emitter and disposed between the walls, and a reflector, disposed on an inner surface of the case, to reflect light emitted from the light emitter and to direct the reflected light through the diffuser plate, wherein each of the louvers is oriented at an obtuse angle relative to the diffuser plate and wherein the light emitter includes an LED. - View Dependent Claims (12, 13, 14, 15, 17, 18, 19, 20)
