Lighting device

A lighting device comprising:

• a housing;
• a coupling member disposed in the housing, having a recess, and comprising a first surface and a second surface which are disposed in the recess;
• and
• a light source unit comprising a first body and a second body,
• wherein each of the first surface and the second surface has a first recess and a second recess which is disposed under the first recess,
• wherein each of the first body and the second body comprises a coupling unit coupled to the coupling member,
• wherein the coupling unit comprises a projection being inserted into at least one of the first recess and the second recess.

A lighting device comprising:

• a housing comprising an upper surface, a first side surface, a second side surface facing the first side surface, a third side surface and a fourth side surface facing the third side surface;
• a coupling member coupled to the upper surface, having a recess, and comprising a first end coupled to the first side surface and a second end coupled to the second side surface;
• a reflector comprising a first reflector coupled between the third side surface and the coupling member and a second reflector coupled between the fourth side surface and the coupling member;
• a light source unit coupled to the coupling member and comprising a first end coupled to the first side surface and a second end coupled to the second side surface,
• wherein the light source unit comprises a first lighting module emitted lights to the first reflector and a second lighting module emitted lights to the second reflector.
