A lamp housing inserted into an installation-opening has an outer surface and an inner surface, a slot going through the outer surface into the inner surface, and a locking device connected to the outer surface. The locking device has an elongated member with a protruding part. The protruding part has a bottom and top part with a pushing-surface and a contacting-surface. The elongated member pivots between a first and second position. In the first position, the bottom part is inside the slot, and the top part is inside the housing, whereby the contacting-surface and pushing-surface are inside the housing. In the second position, the bottom part is outside the slot, and the top part is partly inside the slot, whereby the contacting-surface contacts the outer surface and the pushing-surface is between the outer and inner surface, whereby the housing can be wedged in the installation-opening by the elongated member.

This application is a U.S. National stage of International Application No. PCT/DK2016/050310, which was filed on Sep. 27, 2016 and which claims priority from Danish Application No. PA 2015 70611 filed on Sep. 28, 2015. The entire contents of these applications are incorporated herein by reference in their entirety.
The present invention relates to a lamp housing with a locking device, in particular, a locking device that is able to lock the lamp housing in an installation opening. More particular, the present invention relates to a locking device that can be operated with one hand and from within the lamp housing.
In typical ceiling-mounted lamp housings, two hands are required to install it in an installation opening, in particular because the locking mechanisms typically are spring-loaded and needs to be operated from outside the lamp housing. When installing ceiling-mounted lamp housings, it is typical that a ladder is needed to stand on. Thus, using two hands while standing on a ladder is a dangerous job.
FIG. 1 shows an embodiment of the locking device according to the present invention from a perspective.
FIG. 2 shows an embodiment of the locking device according to the present invention from a side view.
FIG. 3 shows an embodiment of the locking device according to the present invention from a top view.
Locking Device
As previously described, the locking device may in one embodiment of the present invention be a non-spring-loaded locking device.
In another embodiment of the present invention, the locking device is formed as a pawl. A pawl or a locking pawl is generally known for being used in connection with a toothed wheel. However, the effect of a pawl is that is by it shape stops or locks or releases a mechanism. The pawl, generally the locking device, as herein disclosed locks the locking device itself into the slot in the second position when the locking pawl is pushed via the pushing-surface from the first position to the second position, at least when being placed in the installation-opening. In one embodiment, it is the installation-opening that prevents the locking pawl from going further away from the outer surface.
