Abstract

Provided is a kit for assembling a luminaire comprising a bendable reflective canopy and a plurality of frame sections which define a frame and a light exit window of the luminaire. The frame sections include a pair of opposing side sections with an engagement member and side sections. The reflective canopy comprises a pair of opposing edge portions, each edge portion engaging with one of the engagement members when assembling the luminaire. The opposing side sections are spaced by the further side sections such that the reflective canopy is bent when the edge portions are engaged with the engagement members so as to cause the reflective canopy to arch over the light exit window. Solid state lighting elements are mounted on one of the side sections such that at least a part of the light emitted is redirected by the arched reflective canopy towards the light exit window.

First claim

The invention claimed is:

1. A kit for assembling a luminaire by an end user, comprising:
a bendable reflective canopy extending between a pair of opposing edge portions;
a plurality of frame sections for defining a frame delimiting a light exit window of the luminaire, the frame sections including a pair of opposing side sections and a pair of further side sections for spacing the opposing side sections, each of said opposing side sections comprising an engagement member for engaging with one of said edge portions when assembling the luminaire, wherein the opposing side sections are spaced by the further side sections such that the reflective canopy arches over the light exit window when the edge portions are engaged with said engagement members; and
a plurality of solid state lighting elements, wherein each solid state lighting element is mounted on one of said side sections such that when the luminaire is assembled at least a part of its luminous output is redirected by said bendable reflective canopy towards the light exit window;
wherein the engagement member is a fastening member, each edge portion further comprising a further fastening member for engaging with one of said fastening members; the further fastening member comprises at least one protrusion which protrudes from said edge portion, and the fastening member comprises an elongate channel dimensioned to receive one of said edge portions, and a hooked member opposing said channel for receiving and securing said at least one protrusion when the edge portion is received in said elongate channel; and
wherein the bendable reflective canopy comprises a plurality of spatially separated bendable support ribs for supporting said canopy, each of said support ribs extending between the pair of opposing edge portions.

2. The kit of claim 1 , wherein each solid state lighting element is arranged such that, when the luminaire is assembled, a first part of its luminous output is redirected by said bendable reflective canopy towards the light exit window, and a second part of its luminous output is aimed at the light exit window.

3. The kit of claim 1 , wherein the kit further comprises a pair of end panels, each end panel being shaped to cover a gap delimited by one of said further side sections and an arcuate edge of said arched reflective canopy when the luminaire is assembled, wherein said end panels are translucent or opaque.

4. The kit of claim 3 , wherein each end panel comprises one of said further side sections.

5. The kit of claim 1 , wherein said bendable reflective canopy is supplied in an unbent state.

6. The kit of claim 1 , wherein the plurality of frame sections define a fixed frame.

7. The kit of claim 1 , wherein the solid state lighting elements) are grouped in at least one row, each row extending across one of said side sections.

8. The kit of claim 7 , wherein the frame comprises an optical element mounted over each of said rows.

9. The kit of claim 8 , wherein the optical element comprises a diffuser strip or a lens strip.

10. The kit of claim 1 , wherein the luminaire is a troffer and the frame and arched reflective canopy are dimensioned to fit into a ceiling recess when said luminaire is assembled.

11. A method of assembling a luminaire using the kit of claim 1 comprising:
engage one of the edge portions of the bendable reflective canopy with the engagement member located on the side section of the frame, wherein the hooked member receives and secures the at least one protrusion when the edge portion is received in the elongate channel;
bending the bendable reflective canopy such that it arches over said light exit window; and
engaging the further edge portion which opposes said edge portion with the further engagement member located on the further side section which opposes said side section, wherein the hooked member receives and secures the at least one protrusion when the edge portion is received in the elongate channel.

12. A luminaire assembled from the kit of claim 1 .

13. A modular ceiling kit comprising the kit of claim 1 of the assembled luminaire.
