Abstract

A lighting fixture including a housing having a chamber defined by a surrounding wall, at least one power-supply unit within the chamber, and a slidable interlock securing the power-supply unit to the surrounding wall. The interlock includes a linear groove on one of the power-supply unit and the wall, and a mating projection on the other of the power-supply unit and the wall and slidably receivable into the groove. The power-supply unit is readily securable within the chamber by slidable engagement with the surrounding wall. It is preferred that the power-supply unit be secured closely against the fixture-exterior wall-portion, thus facilitating heat transfer from the power-supply unit to outside the fixture.
