摘要：
A modular ceiling kit comprising a luminaire arrangement and a mounting frame (12) is disclosed. The luminaire arrangement has a luminaire (20) with a first light exit window (22) framed by a rim (25). The mounting frame (12) has an aperture (13) for receiving the luminaire (20). The luminaire arrangement also has a component (30) that is mountable in between the mounting frame (12) and the luminaire (20). The component (30) has a first light exit window (22) framed by a rim (25). The component (30) comprises a second light exit window (35) larger than the first light exit window (22), the second light exit window (35) being delimited by a side wall arrangement (33) extending away from the second light exit window (35), wherein the component (30) is dimensioned such that when the component (30) is positioned on the luminaire (20), the component (30) obscures the rim (25) and the sidewall arrangement (33) creates a clearance (40) between the first light exit window (22) and the second light exit window (35).
技术问题语段：
The technical problem addressed in this patent is the aesthetically unsatisfactory appearance of suspended ceiling luminaires that have a rim around their light exit window, as this rim is clearly visible when the luminaire is in use. The patent proposes a modular ceiling kit comprising a luminaire arrangement and a mounting frame, wherein the luminaire has a first light exit window framed by a rim, and a component that can cover the first light exit window and create a clearance between the first and second light exit windows, thereby improving the overall appearance of the luminaire.
技术功效语段：
The present invention relates to a modular ceiling kit comprising a luminaire arrangement and a mounting frame. The luminaire arrangement comprises a luminaire with a first light exit window framed by a rim, and a component that can cover the first light exit window. The component has a second light exit window that is larger than the first light exit window and is positioned to create a clearance between the two windows. This clearance improves the appearance of the luminaire by making the perimeter of the rim invisible. The invention aims to provide a more aesthetically pleasing appearance for suspended ceiling luminaires.
权利要求：
CLAIMS:
1. A modular ceiling kit comprising a luminaire arrangement and a mounting frame (12),
wherein the luminaire arrangement comprises a luminaire (20) having a first light exit window (22) framed by a rim (25),
wherein the mounting frame (12) comprises an aperture (13) for receiving the luminaire (20),
wherein the luminaire arrangement further comprises a component (30) that is mountable in between the mounting frame (12) and the luminaire (20),
wherein the component (30) comprises a second light exit window (35) delimited by a side wall arrangement (33) extending away from the second light exit window (35), and
wherein the component (30) is dimensioned such that when the component (30) is positioned on the luminaire (20), the component (30) extends over the rim (25) and the sidewall arrangement (33) creates a clearance (40) between the first light exit window (22) and the second light exit window (35).
2. The modular ceiling kit of claim 1, wherein the second light exit window (35) comprises a translucent sheet (32) from which the side wall arrangement (33) extends. 3. The modular ceiling kit of claim 2, wherein a major surface of the translucent sheet (32) opposite the clearance (40) carries at least one embossed shape (34).
4. The modular ceiling kit of claim 3, wherein the at least one embossed shape (34) covers only part of the major surface.
5. The modular ceiling kit of any of claims 2-4, wherein the translucent sheet (32) comprises a stepped profile in a direction opposite to the direction in which the sidewall arrangement (33) extends.
6. The modular ceiling kit of any of claims 2-5, wherein the component (30) is a diffuser for the luminaire (20).
7. The modular ceiling kit of any of claims 2-6, wherein the component (30) is made of a polymer material.
8. The modular ceiling kit of any of claims 1-7, wherein the sidewall arrangement (33) comprises a reflective surface arrangement facing the clearance (40). 9. The modular ceiling kit of claim 8, wherein the sidewall arrangement (33) is a curved or angled sidewall arrangement defining a cove delimiting the clearance (40).
10. The modular ceiling kit of any of claims 1-9, further comprising a plurality of fastening members (50) for fastening the component (30) to the luminaire (20).
11. The modular ceiling kit of claim 1 , wherein the luminaire (20) comprises a light guide (27) having a major surface facing or defining the first light exit window (22).
12. The modular ceiling kit of claim 11, further comprising a plurality of solid state lighting elements (26) arranged along at least one edge of the light guide (27).
13. The modular ceiling kit of claim 1, further comprising a plurality of ceiling elements (14) for mounting in a plurality of further apertures of the mounting frame (12).
