9 . The lighting device assembly of claim 1 , wherein

the first bracket is rotatably supported by the second bracket; and

the second bracket is rotatably supported by the housing.

10 . A lighting device assembly, comprising:

an optic assembly comprising a light source;

a housing comprising a cavity in which the at least a portion of the optic assembly is received, wherein the housing is configured to secure the lighting device assembly to a wall, a ceiling, or a surface;

a heat sink configured to couple the optic assembly to an opening of the housing that defines the cavity, wherein the heat sink comprises a hinged aiming mechanism configured to movably couple the optic assembly to the housing to allow the light source to move relative to the housing, wherein the hinged aiming mechanism of the heat sink comprises:

a first bracket supporting a first movement relative to the housing; and

a second bracket supporting a second movement relative to the housing,

wherein the second bracket comprises a collar to engage a groove located at or adjacent to the opening of the housing, at least a portion of the optic assembly is exposed through the opening, the collar is to rotate along the groove.

11 . The lighting device assembly of claim 10 , wherein the second bracket comprises an engagement portion extending from the collar, the engagement portion to rotatably engage the first bracket.

12 . The lighting device assembly of claim 11 , wherein the engagement portion extends inward from the opening of the housing into the cavity.

13 . A lighting device assembly, comprising:

an optic assembly comprising a light source;

a housing comprising a cavity in which the at least a portion of the optic assembly is received, wherein the housing is configured to secure the lighting device assembly to a wall, a ceiling, or a surface;

a heat sink configured to couple the optic assembly to an opening of the housing that defines the cavity, wherein the heat sink comprises a hinged aiming mechanism configured to movably couple the optic assembly to the housing to allow the light source to move relative to the housing, wherein the hinged aiming mechanism of the heat sink comprises:

a first bracket supporting a first movement relative to the housing; and

a second bracket supporting a second movement relative to the housing,

wherein

the first bracket comprises a middle portion and at least one side portion supporting the middle portion;

the middle portion extends over the optics assembly; and

the at least one side portion is rotatably coupled to the second bracket.

14 . The lighting device assembly of claim 13 , wherein

the at least one side portion comprises two side portions on either side of the middle portion; and

the two side portions are rotatably coupled to the second bracket.

15 . The lighting device assembly of claim 14 , wherein the two side portions and the middle portion form an arched shape defining a space configured to accommodate at least a portion of the optic assembly.

16 . A lighting device assembly, comprising:

an optic assembly comprising a light source;

a housing comprising a cavity in which the at least a portion of the optic assembly is received, wherein the housing is configured to secure the lighting device assembly to a wall, a ceiling, or a surface;

a heat sink configured to couple the optic assembly to an opening of the housing that defines the cavity, wherein the heat sink comprises a hinged aiming mechanism configured to movably couple the optic assembly to the housing to allow the light source to move relative to the housing, wherein the hinged aiming mechanism of the heat sink comprises:

a first bracket supporting a first movement relative to the housing; and

a second bracket supporting a second movement relative to the housing,

wherein the first bracket transfers heat from the light source to the cavity of the housing by radiating heat from the light source toward the cavity of the housing; and

the first bracket transfer heat from the light source to the second bracket by conduction.
