Patent ID: 8061867

Claim:
A lighting device comprising: a housing; a coupling member being coupled to an inner upper surface of the housing, having a first insertion groove formed in a middle part of the coupling member in a direction of the inner upper surface of the housing, and having a first connection terminal provided in the middle of the first insertion groove; at least one reflector coupled between an inner wall surface of the housing and an outer wall surface of the coupling member; and a light source unit, wherein the light source unit comprises: a first body having a first coupling unit formed in an upper part of the first body, the first coupling unit coupled to the coupling member through the first insertion groove in an attachable and removable manner, having a first sloping surface toward the at least one reflector, and facing the at least one reflector, the first sloping surface formed on a side of a lower part of the first body, and having a first hinge protruding formed on an opposite side of the lower part of the first body; a second body having a second coupling unit formed in an upper part of the second body, the second coupling unit coupled to the coupling member through the first insertion groove in an attachable and removable manner, having a second sloping surface toward at least one reflector and facing the at least one reflector, the second sloping surface formed on a side of a lower part of the second body, and having a second hinge protruding formed on an opposite side of the lower part of the second body; a middle body having a second insertion groove formed respectively on both sides of a lower part of the middle body, allowing the first body and the second body to be coupled to both sides of the middle body in an attachable and removable manner by inserting the first hinge and the second hinge into the second insertion groove respectively, and having a second connection terminal disposed in an upper part of the middle body, the second connection terminal electrically connected to the first connection terminal, when the light source unit is coupled to the coupling member; and a main light emitting diode module disposed on the first sloping surface and the second sloping surface respectively.
