Abstract

A lighting module may comprise a housing, a window frame mounted at a front side of the housing, a window mounted at a front plane of the window frame, the window comprising a window front face spanning a front plane length and first and second window sidewalls extending rearwards from first and second edges of the window front face, and an array of light-emitting elements within the housing, the array aligned with and emitting light through a window front plane and through the first and second window sidewalls.

Claims

1. A lighting module, comprising:

a window casing;

a window mounted at a window casing front face, wherein

a window front face spans a length of the window casing front face, and

the window front face is flush with the window casing front face; and

an array of light-emitting elements positioned behind the window casing to emit light through the window.

2. The lighting module of claim 1, further comprising a window frame, wherein the window front face is flush with a window frame front side.

3. The lighting module of claim 1, wherein

the window casing comprises a window frame, and

the window front face is flush with a window frame front side.

4. The lighting module of claim 1, wherein

first and second window sidewalls extend rearward from left and right edges of the window front face, respectively, and

rearward ends of the first and second window sidewalls are flush with left and right window casing sidewalls, respectively.

5. The lighting module of claim 4, wherein the first and second window sidewalls are flush with the left and right window casing sidewalls, respectively.

6. The lighting module of claim 4, wherein the first and second window sidewalls are flush with left and right window frame sidewalls, respectively.

7. The lighting module of claim 4, wherein the rearward ends of the first and second window sidewalls extend rearward from the window beyond the array of light-emitting elements.

8. The lighting module of claim 4, wherein

the first and second window sidewalls extend rearwards from the left and right edges of the window front face at first and second angles, respectively, and

one of the first and second angles is 90°

.

9. The lighting module of claim 4, wherein

the first and second window sidewalls extend rearwards from the left and right edges of the window front face at first and second angles, respectively, and

one of the first and second angles is greater than 90°

.

10. The lighting module of claim 4, wherein

the first and second window sidewalls extend rearwards from the left and right edges of the window front face at first and second angles, respectively, and

the first and second angles are greater than 90°

.

11. The lighting module of claim 1, wherein the window casing front side and the window front face are flushly convex or flushly concave.

12. The lighting module of claim 1, wherein the array of light-emitting elements comprises a linear array of light-emitting elements, the linear array of light-emitting elements comprising a middle portion in between two end portions, wherein:

the middle portion comprises a plurality of light-emitting elements distributed over the middle portion with a first, larger, spacing throughout the middle portion; and

each of the two end portions comprise a plurality of light-emitting elements distributed over the two end portions with a second, smaller, spacing throughout each of the two end portions.

13. The lighting module of claim 8, wherein a third spacing between the middle portion and each of the two end portions is greater than the second spacing and less than the first spacing.

14. The lighting module of claim 10, wherein:

the plurality of light-emitting elements in the middle portion are supplied with a first, larger, drive current; and

the plurality of light-emitting elements in the two end portions are supplied with a second, smaller, drive current.

15. A method of irradiating light, comprising:

irradiating light from an array of lighting modules, each of the array of lighting modules comprising;

a window casing;

a window mounted at a window casing front side, wherein the window comprises a window front face spanning a length of the window casing front side, and wherein the window front face is flush with the window casing front side;

first and second window sidewalls extending rearwards from left and right edges of the window front face, respectively; and

an array of light-emitting elements positioned within the window casing to emit light through the window front face and through the first and second window sidewalls.

16. The method of claim 15, further comprising arranging adjacent lighting modules of the array of lighting modules in a side by side manner, including aligning the window front face of each of the adjacent lighting module to be coplanar.

17. The method of claim 16, wherein arranging adjacent lighting modules of the array of lighting modules in a side by side manner further includes positioning the right edge of the window front face of one of the adjacent lighting modules directly adjacent to the left edge of the window front face of the other adjacent lighting module.

18. The method of claim 15, wherein

the first and second window sidewalls extend rearwards from the left and right edges of the window front face at first and second angles, respectively, and

one of the first and second angles is 90°

.

19. The method of claim 15, wherein

the array of light-emitting elements of each of the array of lighting modules further comprises a linear array of light-emitting elements,

the linear array of light-emitting elements includes a middle portion in between two end portions,

the method further comprising,

supplying a first, larger, drive current to each of the plurality of light-emitting elements in the middle portion, and

supplying a second, smaller, drive current to each of the plurality of light-emitting elements in the two end portions.

20. A lighting system comprising:

a power supply;

a cooling subsystem;

a light-emitting subsystem comprising,

a window casing;

a window frame mounted at a window casing front side;

a window mounted at a front plane of the window frame, the window comprising a window front face spanning a front plane length, wherein the window front face is flush with a window frame front side, and first and second window sidewalls extending rearwards from first and second edges of the window front face at first and second angles, respectively; and

a linear array of light-emitting elements within the window casing, the linear array aligned with and emitting light through a window front plane and through the first and second window sidewalls, wherein;

window sidewalls at the first and second edges of the window front face are aligned flush with window casing sidewalls, the window sidewalls extending perpendicularly back from the front plane, and

the linear array of light-emitting elements comprises a middle portion in between two end portions, and

a controller, including instructions executable to supply a first, larger, drive current to each of a plurality of light-emitting elements in the middle portion, and supply a second, smaller, drive current to each of a plurality of light-emitting elements in the two end portions.
