Lighting device assembly with adjustment mechanism

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 collar coupled to an opening of the housing that defines the cavity, wherein
• the optic assembly is coupled to the collar;
• the collar comprises an adjustment member configured to adjust, relative to the housing, at least one of a position of the collar, a position of the optic assembly, or a position of the light source, wherein
• the adjustment member comprises:
• a first groove extending along a vertical axis of a lateral side of the collar;
• a guide plate slidably coupled to the lateral side of the collar;
• and
• a fastener configured to fasten the guide plate to the first groove at a location along the vertical axis of the first groove;
• the lateral side of the collar comprises a first protruding member and a second protruding member configured to hold the optic assembly when the optic assembly is coupled to the collar;
• and
• the first groove and the fastener are between the first protruding member and the second protruding member.

An adjustment member for adjusting a position of an optic assembly relative to a housing configured to a wall, a ceiling, or a surface, wherein the adjustment member comprises:

• a collar slidably coupled to the housing;
• a first groove extending along a vertical axis of a lateral side of the collar;
• a guide plate slidably coupled to the lateral side of the collar;
• a fastener configured to fasten the guide plate to the first groove at a location along the vertical axis of the first groove;
• an interference pattern on the lateral side of the collar extending along the vertical axis of the lateral side of the collar, wherein the interference pattern defines a plurality of steps along the vertical axis, the fastener configured to fasten the guide plate to the interference pattern at or over at least one of the plurality of steps when the fastener fastens the guide plate to the first groove at the location along the vertical axis of the first groove, wherein
• the adjustment member comprises a back plate slidably coupled to the lateral side of the collar;
• the guide plate and the back plate are located on opposite surfaces of the lateral side of the collar;
• the guide plate is coupled to the back plate;
• and
• at least one of the guide plate or the back plate is fixed relative to the housing.
