[0006] In one example, the first and second LED arrays may include respective first and second multiple light emitting areas separated by respective first and second boundaries. The first and second boundaries may be configured in slightly different patterns. At least one lens may collimate light from the first LED array to form a first illumination and collimate light from the second LED array to form a second illumination, illuminating the scene with the first and second illuminations. The first boundary may form a first dark band in the first illumination. The second boundary may form a second dark band in the second illumination, which may be slightly offset from the first dark band in the scene. The offset helps reduce or eliminate the dark band in the overall illumination in the scene that may be present if only one LED array and lens are used.

[0007] 1 illustrates a side view of an example lighting system 100, such as for a camera 102, according to some examples. The camera 102 can capture an image of a scene 104 during an exposure period of the camera 102. In FIG. 1, the scene 104 is shown as a happy cat, although other suitable scenes may be used.

[0008] The lighting system 100 may include a first light emitting diode (LED) array 106A. The first LED array 106A may include a plurality of first light emitting areas 108A capable of emitting a first light 110A. The first light emitting areas 108A may be separated by a first boundary (e.g., an area on the first LED array 106A that does not emit light).

[0009] The lighting system 100 may include a second LED array 106B. The second LED array 106B may include a plurality of second light-emitting areas 108B that can emit a second light 110B. The second light-emitting areas 108B may be separated by second boundaries that correspond to the first boundaries in a one-to-one correspondence.

[0010] In some examples, the first LED array 106A and / or the second LED array 106B may be optionally covered by a wavelength conversion layer, such as a phosphor. The first LED array 106A and / or the second LED array 106B may generate a first light having a first wavelength, such as the blue or violet portion of the visible spectrum. The wavelength conversion layer may absorb some or all of the first light and emit a second light having a second wavelength longer than the first wavelength, such as the yellow portion of the visible spectrum. The total light output may be the second light or a combination of the first light and the second light. In some examples, the phosphor and geometry of the first LED array 106A and / or the second LED array 106B may be adjusted to output light with a specified peak wavelength and / or a specified wavelength spectrum.

[0011] The illumination system 100 can include at least one lens 114 capable of collimating the first light 110A to form a first illumination 116A and illuminating the scene 104 with the first illumination 116A. The at least one lens 114 can collimate the second light 110B to form a second illumination 116B and illuminating the scene 104 with the second illumination 116B.

[0012] In the configuration of FIG. 1, the at least one lens 114 may include a first lens 114A capable of collimating the first light 110A to form a first illumination 116A, and a second lens 114B capable of collimating the second light 110B to form a second illumination 116B.

[0013] In some examples, a first central axis can extend from the first LED array 106A through the center of the first lens 114A to the scene 104. In some examples, a second central axis can extend from the second LED array 106B through the center of the second lens 114B to the scene 104. In some examples, the first central axis can be substantially parallel to the second central axis.

[0014] In other configurations, such as that shown in FIG. 5 and described below, the at least one lens 114 may include only a single lens, with an additional beam splitter combining the first light 110A and the second light 110B such that the single lens can collimate both the first light 110A and the second light 110B.

[0015] In some examples, the lighting system 100 may optionally further include a controller 128. The controller 128 may receive a specified lighting pattern. The controller 128 may power the first LED array 106A in response to the specified lighting pattern such that the first lighting 116A corresponds to the specified lighting pattern. The controller 128 may power the second LED array 106B in response to the specified lighting pattern such that the second lighting 116B corresponds to the specified lighting pattern.

[0016] In some examples, the lighting system 100 may optionally further include a housing 130. The first LED array 106A and the second LED array 106B may be disposed in the housing 130. The first lens 114A and the second lens 114B may be disposed in or on the housing 130. The first lens 114A and the second lens 114B may direct the first illuminator 116A and the second illuminator 116B, respectively, away from the housing 130.

[0017] In some examples, the lighting system 100 may optionally further include a camera 102 disposed within or on a housing 130. The camera 102 may collect a first illumination 124A reflected from a scene 104 and a second illumination 124B reflected from the scene 104. The camera 102 may include a lens 122 for forming an image of the scene 104 from the collected light. A multi-pixel sensor 126 in the camera 102 may detect the image.

[0018] In some examples, the camera 102 may be disposed between the first lens 114A and the second lens 114B.

[0019] The first lens 114A can collimate the first light 110A, such as by placing the first LED array 106A in a focal plane of the first lens 114A, so that features in translation space on the first LED array 106A can correspond to features in angle space in the first illumination 116A. For example, the bright and dark areas of the first LED array 106A can correspond to the bright and dark areas in angle space that emerge from the illumination system 100. Because the scene 104 can be relatively far from the illumination system 100 compared to the distance and size of the elements in the illumination system 100, the bright and dark areas in angle space can correspond to the bright and dark areas in the illumination pattern that the illumination system projects onto the scene 104.

[0020] Similarly, the second lens 114B can collimate the second light 110B, such as by placing the second LED array 106B in a focal plane of the second lens 114B, so that features in translation space on the second LED array 106B can correspond to features in angle space in the second illumination 116B. Because the scene 104 can be relatively far from the illumination system 100 compared to the distance and size of elements in the illumination system 100, the bright and dark regions in angle space can correspond to bright and dark areas in the illumination pattern that the illumination system projects onto the scene 104.

[0021] Furthermore, because the distance to the scene 104 may be significantly greater than the spacing between the first lens 114A and the second lens 114B, the spacing between the first lens 114A and the second lens 114B may be ignored when determining where a particular light ray at a particular propagation angle will strike the scene 104. As a result, it may be assumed that a first light ray propagating at a propagation angle specified in the first illumination 116A and a second light ray propagating at a propagation angle specified in the second illumination 116B may arrive at the same location in the scene 104. Figures 2-4 below show examples of illumination patterns in the scene 104.

[0022] Figure 2 illustrates a front view of an example of a lighting pattern 200 in a scene 104, according to some examples. Figure 3 illustrates a front view of another example of a lighting pattern 300 in a scene 104, according to some examples. Figure 4 illustrates a front view of another example of a lighting pattern 400 in a scene 104, according to some examples.

[0023] The first light emitting area 108A can form a corresponding first illumination region 202 in the first illumination 116A in the scene 104. The first boundary can form a first dark band 204 in the first illumination 116A in the scene 104. The second light emitting area 108B can form a corresponding second illumination region 206 in the second illumination 116B in the scene 104. Each second illumination region 206 can at least partially overlap with a corresponding first illumination region 202 in the scene 104. The second boundary can form a second dark band 208 in the second illumination 116B in the scene 104.

[0024] The second dark band 208 can be offset from the corresponding first dark band 204 in the scene. The offset can help reduce or eliminate dark bands in the combined first and second illuminations 116A and 116B that may be present if the second dark band 208 was not offset from the first dark band 204 and thus the second boundary (e.g., the non-emitting area of ​​the second LED array 106B) was not offset from the first boundary (e.g., the non-emitting area of ​​the first LED array 106A). Suitable offsets can include greater than 50% of the width of the dark band, greater than 100% of the width of the dark band, greater than 150% of the width of the dark band, greater than 200% of the width of the dark band, or others. In some examples, the controller 128 can be trained to use a suitable offset and / or can use a programmable offset.

[0025] In some examples, the plurality of second light-emitting areas 108B may correspond to the plurality of first light-emitting areas 108A in a one-to-one correspondence. For example, the plurality of first light-emitting areas 108A and the plurality of second light-emitting areas 108B may be powered or controlled together to generate illumination together. The one-to-one correspondence may help ensure that illumination is generated with the same resolution (e.g., number of light-generating elements or pixels) as the first LED array 106A and / or the second LED array 106B. In other examples, the correspondence may not be one-to-one, such as a single light-generating element of one LED array corresponding to multiple light-generating elements of the other LED array. Other configurations are possible.

[0026] In some examples, a first dark band 204 in a first illumination 116A in a scene 104 may be substantially parallel to a second dark band 208 in a second illumination 116B in a scene 104. For example, the first dark band 204 may correspond to a boundary extending along a first direction and a boundary extending along a second direction that is orthogonal to the first direction. The second dark band 208 may also correspond to a boundary extending along the first direction and a boundary extending along the second direction.

[0027] In some examples, the plurality of first light-emitting areas 108A may be arranged in a first rectilinear array along orthogonal first and second dimensions. In some examples, each first boundary may be arranged as an elongated area extending along one of the first dimension or the second dimension. In some examples, the plurality of second light-emitting areas 108B may be arranged in a second rectilinear array along the first and second dimensions. In some examples, each second boundary may be arranged as an elongated area extending along one of the first dimension or the second dimension.

[0028] In some examples, such as the configurations of Figures 2 and 3, at least one first boundary (corresponding to the first dark band 204) can extend in a continuous line along the entire extent of the first linear array.

[0029] 2-4, at least one first boundary (corresponding to a first dark band 204) can include a discontinuity. For example, the at least one first boundary can include a first segment and a second segment that is laterally offset from the first segment.

[0030] In some examples, such as the configuration of FIG. 4, at least one first boundary (corresponding to first dark band 204) can include multiple parallel segments.

[0031] In some examples, such as the configurations of Figures 2-4, at least one second boundary (corresponding to the second dark band 208) can extend in a continuous line along the entire extent of the second linear array.

[0032] In some examples, such as the configuration of FIG. 4, at least one second boundary (corresponding to second dark band 208) may include a discontinuity.

[0033] In some examples, such as the configuration of FIG. 4, at least one second boundary (corresponding to second dark band 208) can include multiple parallel segments.

[0034] FIG. 5 illustrates a side view of an example illumination system 500, such as for camera 102, according to some examples.

[0035] 1, the illumination system 500 uses a single lens 114 to replace the first lens 114A and the second lens 114B, and includes an additional beam splitter 502 to combine the first light 110A with the second light 110B and direct the combined first light 110A and second light 110B to the lens 114. The beam splitter 502 can be formed as a cube beam splitter, with a beam splitting coating disposed on the hypotenuse of the cube. The beam splitter 502 may alternatively be formed as a plate beam splitter, a polygonal prism, or other suitable beam splitting geometry.

[0036] 6 illustrates a flowchart of an example of a method 600 for providing illumination, in accordance with some examples. Method 600 can be performed by lighting system 100, lighting system 500, or other suitable systems. Method 600 for providing illumination is just one method of providing illumination, and other suitable methods may be used.

[0037] A first light may be emitted from a plurality of first light-emitting areas of a first LED array at operation 602. The first light-emitting areas may be separated by a first boundary.

[0038] At operation 604, the first light may be collimated to form a first illumination.

[0039] At operation 606, a scene may be illuminated with a first illumination. The first light emitting area may form a corresponding first illumination region in the first illumination in the scene. The first boundary may form a first dark band in the first illumination in the scene.

[0040] At operation 608, a second light may be emitted from a plurality of second light-emitting areas of the second LED array. The second light-emitting areas may be separated by second boundaries corresponding to the first boundaries in a one-to-one correspondence.

[0041] At operation 610, the second light may be collimated to form a second illumination.

[0042] At operation 612, the scene may be illuminated with a second illumination. The second light emitting areas may form corresponding second illumination regions in the second illumination in the scene. Each second illumination region may at least partially overlap with a corresponding first illumination region in the scene. The second boundaries may form second dark bands in the second illumination in the scene. The second dark bands may be offset from the corresponding first dark bands in the scene.

[0043] The method 600 may optionally further include the controller receiving a specified lighting pattern.

[0044] The method 600 may optionally further include powering the first LED array in response to the specified lighting pattern such that the first lighting corresponds to the specified lighting pattern.
