Abstract

A light fitting, particularly a built-in light fitting for ceilings and/or walls, includes an embeddable housing for receiving lighting means, a reflector, a housing frame, a functional frame, which can be detached at least partially from the housing frame and a locking device, which acts between the housing frame and functional frame. The locking device includes at least one wire spring, the wire spring being provided with a spring section extending between two locking elements formed in end areas of the wire spring. The locking elements cooperate with a respective locking receiving element in the functional frame. A wire limb is respectively formed between the spring section and locking elements. When the wire limb is pivoted and the spring section is deformed as a result, it is possible to modify the relative position of the locking elements relative to each other.

Dependent claims

A lamp, in particular a built-in lamp for ceilings and/or walls, comprising:

a built-in housing (52) designed for the reception of a light source, a reflector (14) and associated mechanical and electrical and/or electronic components;
a housing frame (56) connected to the housing (52) and a functional frame (10) at least regionally releasable from the housing frame (56);
and
a closing arrangement active between the housing frame (56) and the functional frame (10), wherein
the closing arrangement has at least one wire spring (28),
the wire spring (28) having a spring portion (30), which extends between two latch elements (26) formed in end regions of the wire spring (28), the latch elements (26) cooperating with a respective latch receiver (16) in the functional frame (10) and wherein
a respective wire limb (36) is formed between the spring portion (30) and the latch elements (26) so that the relative position of the latch elements (26) can be modified with respect to one another by a pivoting of the wire limbs (36) and a deformation of the spring portion (30) associated therewith.
