An LED lighting device with an elongated lighting cavity formed by two opposed elongated curved or angled structures is disclosed. The opposed elongated curved or angled structures are positioned such that the concave surfaces or acute angles of the two opposed structures are juxtaposed with respect to each to form the elongated lighting cavity having elongated openings. The LED lighting device included arrays of LED light engines attached to one or more surfaces of one or more of the two opposed elongated structures within the lighting cavity to emit light from the elongated openings. In accordance with the embodiments of the invention the relative positions of the opposed elongated curved or angled structures are adjustable to change the lighting profile emitted from the elongated openings.

An electrical connector for electrically coupling an electrical accessory to a furniture item may include a support column and a power interface set that may be provided in an interior of the support column. The power interface set may include an electrically contactable lower surface that may be spaced apart from an end of the support column. A distance between the electrically contactable lower surface of the power interface set and the end of the support column may be equal to a length of a retention portion of the support column. The retention portion and the electrically contactable lower surface of the power interface set may be together dimensioned for connection to an external power source coupled to the furniture item.
