1. A lighting assembly comprising at least one lighting unit, each lighting unit comprising:
- a housing comprising a base portion and an outer portion, the housing being configured to define an internal cavity and a gap around an outer perimeter of the housing between the base portion and the outer portion;
a circuit board disposed within the housing;
at least one light emitting diode carried by the circuit board; and
an electrical wire having a first end for electrical connection to the circuit board, the electrical wire being configured to be wound around a hub disposed radially inward of the gap; and
a mounting plate configured to be secured to an external surface, and including a plurality of tabs that snap into engagement with the base portion of the housing to secure the lighting unit to the external surface; and
wherein at least a portion of the gap is sized to apply a retaining force to retain a wound portion of the electrical wire within the internal cavity, such that a user applied pulling force on the electrical wire overcomes the retaining force to withdraw the user selected amount of the wound portion of the electrical wire.

Abstract
A lighting assembly includes a lighting unit having a housing defining an internal cavity and an opening. A light source is assembled within the internal cavity of the housing. An electrical wire is electrically connected to the light source at a first end and is configured to be contained at least in part within the housing. The opening is configured to permit withdrawal of a user selected amount of the electrical wire from within the internal cavity and/or to permit a user selected amount of the electrical wire to be inserted into the internal cavity.

14. A lighting assembly comprising at least one lighting unit, each lighting unit comprising:
-
a housing configured to define an internal cavity and a gap around an outer perimeter of the housing between a base portion and an outer portion; a circuit board disposed within the housing; at least one light emitting diode carried by the circuit board; and an electrical wire having a first end for electrical connection to the circuit board; wherein the housing comprises a first housing member defining a hub and a second housing member forming a substrate thermally coupled to the circuit board, with the first and second housing members together defining a spool member for retaining a wound portion of the electrical wire around the hub when the wound portion of the electrical wire is wound around the hub; and wherein the gap is configured to permit withdrawal of a user selected amount of the wound portion of the electrical wire from within the internal cavity. - View Dependent Claims (15, 16, 17, 18)
