[0005] The invention relates to a frame arrangement for a luminaire to be mounted as a recessed luminaire in a surface.

[0006] BACKGROUND OF THE INVENTION

[0007] In the realm of luminaire design, spring holders play a crucial role. These T- shaped components securely hold coil spring elements in place. However, due to manufacturing constraints, these spring holders are often separate entities from the rest of the product. Attaching the spring holder to the frame arrangement often involves using a metal screw for screwing a metal spring holding part to the frame arrangement. This may be a reliable method, but a cost-intensive method. The need for an additional part, such as metal screw and other parts introduces complexity during assembly. The parts for the frame arrangement may be produced in different locations and most likely from different manufacturers. Furthermore, the workers must handle the multiple parts, align them precisely, and secure them together, which can be time-consuming and prone to assembly errors.
