## Abstract

Presented are concepts for controlling cove lighting. Once such concept provides cove lighting adapted to output decorative light for illuminating the ceiling of an architectural space. The cove lighting comprises a control unit adapted to individually control each of the primary light sources in response to a lighting control signal so that the output decorative light mimics an outdoor lighting condition.

## Claims

### Claim 1

(canceled)

### Claim 2

(canceled)

### Claim 3

(canceled)

### Claim 4

(canceled)

### Claim 5

Cove lighting for positioning in a cove or mounting on a wall, the cove lighting comprising:
an array of individually controllable primary light sources adapted to, when positioned in a cove or mounted on a wall, provide light to an architectural space by projecting decorative light from the array of individually controllable primary light sources onto a ceiling of the architectural space; and
a control unit adapted to individually control a light output of each of the primary light sources in response to a lighting control signal so that the decorative light output from the array of individually controllable primary light sources mimics an outdoor lighting condition,
wherein the primary light sources are controllable as individual pixels for outputting the decorative light as a pixelated sky projection.

### Claim 6 (depends on 5)

The cove lighting of claim 5, wherein the control unit is adapted to individually control the colour, intensity, or colour temperature of the light output from each of the primary light sources in response to the lighting control signal.

### Claim 7 (depends on 5)

The cove lighting of claim 5, wherein the cove lighting is formed from lighting modules each providing at least one of the primary light sources, and wherein the control unit is adapted to control the lighting modules as a single virtual array of primary light sources.

### Claim 8 (depends on 7)

The cove lighting of claim 7, wherein the lighting modules are adapted to be releasably coupled or decoupled to each other so that the lighting modules may be added or removed from the cove lighting to increase or decrease an overall length of the cove lighting.

### Claim 9

(canceled)

### Claim 10 (depends on 5)

The cove lighting of claim 5, further comprising an array of individually controllable secondary light sources adapted to provide direct light for illuminating the architectural space below the ceiling, and wherein the control unit is further adapted to individually control a light output of each of the secondary light sources in response to the lighting control signal so that the direct light mimics the outdoor lighting condition.

### Claim 11 (depends on 5)

The cove lighting of claim 5, further comprising a sensor unit adapted to detect information relating to at least one of: a position of the cove lighting; an orientation of the cove lighting; a current time; a current date; a geographical location of the cove lighting; weather information; a layout of the cove lighting; surroundings of the cove lighting; orientation of at least one of the plurality of primary light sources; a distance from the cove lighting to the ceiling; properties of the ceiling; and one or more dimensions of the cove, and to generate the lighting control signal based on the detected information.

### Claim 12 (depends on 5)

A Cove lighting system comprising a cove lighting of claim 5, and further comprising a processing system adapted to generate the lighting control signal based on one or more of a current time, a current date, a geographical location and weather information.

### Claim 13

A method of controlling cove lighting positioned in a cove or mounted on a wall, the cove lighting comprising an array of individually controllable primary light sources adapted to provide light to an architectural space by projecting decorative light from the array of individually controllable primary light sources onto a ceiling of the architectural space, wherein the method comprises:
generating, based on one or more of a current time, a current date, a geographical location and weather information, a lighting control signal for individually controlling a light output of each of the primary light sources in order that the decorative light output from the array of individually controllable primary light sources mimics an outdoor lighting condition,
wherein the primary light sources are controllable as individual pixels for outputting the decorative light as a pixelated sky projection.

### Claim 14 (depends on 13)

The method of claim 13, further comprising:
detecting information relating to at least one of: a position of the cove lighting; an orientation of the cove lighting; a current time; a current date; a geographical location of the cove lighting; and weather information; a layout of the cove lighting; surroundings of the cove lighting; orientation of at least one of the plurality of primary light sources; a distance from the cove lighting to the ceiling; properties of the ceiling; and one or more dimensions of the cove, and
generating the lighting control signal further based on the detected information.

### Claim 15 (depends on 5)

A computer program product for controlling cove lighting according to claim 5,
wherein the computer program product comprises a computer-readable storage medium having computer-readable program code embodied therewith, the computer-readable program code configured to execute on a processing system.

### Claim 16 (depends on 6)

The cove lighting of claim 6, wherein the cove lighting comprises further lighting modules each providing at least one of the secondary light sources, and wherein the cove lighting comprises a module adjustment arrangement adapted to alter the relative positioning of the lighting modules and further lighting modules in response to an arrangement control signal.

### Claim 17 (depends on 5)

The cove lighting of claim 5, wherein at least one of the array of individually controllable primary light sources and the array of individually controllable secondary light sources comprises a two-dimensional array of light sources adapted to output light in multiple directions.

### Claim 18 (depends on 12)

The cove lighting system of claim 12, wherein the processing system is adapted to generate the lighting control signal further based on at least one of: a position of the cove lighting; an orientation of the cove lighting; a layout of the cove lighting; surroundings of the cove lighting; orientation of at least one of the plurality of primary light sources; a distance from the cove lighting to the ceiling; properties of the ceiling; and one or more dimensions of the cove.

### Claim 19 (depends on 18)

The cove lighting system of claim 18, wherein the processing system is adapted to generate the lighting control signal based on detected information from the sensor unit.
