Exterior lamp mounting adaptor with integrated electrical interface

A mounting adaptor for an electric light fixture to be mounted on an electrical connection box, the mounting adaptor comprising:

• a base and a joining member adapted to be releasably assembled to each other;
• the base comprising:
• a mounting element adapted to mount the base to the electrical connection box;
• an input electrical connection electrically connecting the base to the electrical connection box;
• and
• a first electrical interface;
• the joining member comprising:
• a joint element adapted to mount mechanically the electric light fixture to the joining member;
• and
• a second electrical interface for electrical coupling to the first electrical interface to electrically connect the base to the electric light fixture wherein the first electrical interface couples to the second electrical interface as the joining member is mounted to the base;
• and
• a locking mechanism adapted to lock the base and the joining member in a mounted position relatively to each other, wherein the locking mechanism comprises a resilient member moving from an unlocked position to a locked position during an assembly of the joining member with the base.

A mounting adaptor for an electric light fixture to be mounted on a surface, the mounting adaptor comprising:

• a base and a joining member on which is mounted the electric light fixture, the base and the joining member each having an interfacing face, one of the base and the joining member comprising on its interfacing face a groove, the other one of the base and the joining member comprising on its interfacing face a lip adapted to cooperate with the groove thereby providing a capability to assemble releasably the joining member with the base;
• wherein the base comprises a mounting element adapted to mount the base to the surface;
• wherein each one of the interfacing faces comprises an electrical interface for electrical coupling with the electrical interface of the other one of the interfacing faces when assembling the base and the joining member;
• and
• wherein the lip and the groove form a trapezoid having a narrow top and a broad base.
