[0058] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0059] Here, it should be noted that in order to avoid obscuring the present invention due to unnecessary details, only the structures and / or processing steps closely related to the solution of the present invention are shown in the drawings, and other details less related to the present invention are omitted.

[0060] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover a non - exclusive inclusion, such that a process, method, article or device comprising a series of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article or device.

[0061] The present invention provides an illumination system, and the illumination system will be described below with reference to specific embodiments.

[0062] The illumination system includes a control terminal and a plurality of lighting devices. The lighting device includes at least one light source assembly, and the light source assembly includes a plurality of light emitting units. Each light emitting unit has an independent control address and can be controlled by the following lighting device control method:

[0063] Select a view - finding area, and the view - finding area has a number of pixel positions;

[0064] Establish a first position mapping relationship between the control address of each light emitting unit in the light source assembly and the pixel positions of the view - finding area;

[0065] Import a target image into the view - finding area so that the target image has a number of pixel positions;

[0066] Establish a second position mapping relationship between the pixel positions of the target image and the pixel positions of the view - finding area;

[0067] Based on the first position mapping relationship and the second position mapping relationship, extract the pixel information at the pixel position of the target image corresponding to the pixel position of the viewfinder area, and send the pixel position of the viewfinder area and the pixel information in the target image corresponding to this pixel position to the lighting device.

[0068] Adjust the color of the light emitted by each light-emitting unit based on the pixel information of the target image and the pixel position of the viewfinder area, so that the lighting device displays the style of the target image.

[0069] As Figure 1 shown, in the lighting system of the present invention, the lighting device controls each light-emitting unit to emit light of a color corresponding to the pixel information according to the pixel position of the viewfinder area and the pixel information of the target image corresponding to this pixel position. The entire lighting device then displays the style corresponding to the target image, and the display style is more diverse.

[0070] In this embodiment, the pixel information specifically includes color coordinate information. The control terminal sends the color coordinate information of each control address to the lighting device, and the lighting device controls the light-emitting units at each control address to display corresponding colors according to the color coordinates, and the brightness value is set between 1% and 100% as needed.

[0071] After importing the target image into the viewfinder area, first judge the size of the pixel size of the target image and the pixel size of the viewfinder area. When the pixel size of the target image is larger than the pixel size of the viewfinder area, reduce the pixel size of the target image to adapt to the pixel size of the viewfinder area, and establish a second position mapping relationship between the pixel position of the reduced target image and the pixel position of the viewfinder area; or, directly import the target image into the viewfinder area, and only establish a second position mapping relationship between the pixel position of the target image that matches the pixel size of the viewfinder area and the pixel position of the viewfinder area.

[0072] When the pixel size of the target image is smaller than the pixel size of the viewfinder area, enlarge the pixel size of the target image to fill the viewfinder area, and establish a second position mapping relationship between the pixel position of the enlarged target image and the pixel position of the viewfinder area; or, directly import the target image into the viewfinder area, and only establish a second position mapping relationship for the pixel position of the viewfinder area that matches the pixel size of the target image. At this time, some pixel positions in the viewfinder area are not established with a second mapping relationship with the pixel position of the target image, and the pixel information of the preset background color is directly assigned to the pixel positions in this part of the viewfinder area.

[0073] In this embodiment, the pixel size of the viewfinder area is less than or equal to 1000*1000.

[0074] The viewing area includes any one of a square viewing area, a rectangular viewing area, and a circular viewing area. When the viewing area is a square or a circular viewing area, the target image imported into the viewing area is square; when the viewing area is rectangular, the target image imported into the viewing area is rectangular.

[0075] In some other embodiments, the pixel information further includes brightness information, such as Figure 5 shown, the control terminal packs the color coordinate information, brightness information, and pixel information together and sends them to the lighting device. Figure 5 In it, Bright is the brightness information, and Cx and Cy are the color coordinate information. The lighting device uses the received brightness information as a reference value to set the brightness displayed by the lighting device.

[0076] In some embodiments, the light source assembly 100 includes a plurality of light-emitting basebands 120. Each light-emitting baseband 120 includes a plurality of light-emitting units 110 with the same quantity. The arrangement modes of the light-emitting basebands 120 include horizontal arrangement, vertical arrangement, and circular arrangement, etc.

[0077] The control terminal packs the pixel information of each converted control address, including color coordinates, brightness information, and pixel positions together as scene lighting parameters, and sends the scene lighting parameters to the corresponding lighting device. The lighting device saves the received scene lighting parameters to a scene number. Different scene numbers in the lighting device correspond to different target images. When it is necessary to control the lighting device to display different target images, it only needs to call different scene numbers through the control terminal to achieve, and the whole control process is more convenient and fast.

[0078] Such as Figure 6 shown, in some embodiments, the control terminal can be an APP on various mobile devices. Users can remotely control the lighting device for adjustment through the APP, specifically including the following steps:

[0079] Select the target image through the APP;

[0080] The APP sends an instruction to call the target image to the cloud;

[0081] The cloud filters the lighting devices adapted to the target image and sends an instruction to call the scene number corresponding to the target image to the gateway connected to these lighting devices;

[0082] Each gateway broadcasts and calls the scene number to the lighting devices connected to it;

[0083] The lighting device adapted to the target image responds to the broadcast call of the gateway and displays the style of the target image.

[0084] Such as Figure 7As shown, in some embodiments, the control terminal may be a panel in the lighting device. The steps of controlling the lighting device through the panel for adjustment specifically include:

[0085] Select a target image through the panel;

[0086] The panel sends an instruction to the gateway to call the scene number corresponding to the target image;

[0087] The gateway analyzes the instruction through the engine and sends an instruction to call the scene number to other gateways within the local area network;

[0088] Each gateway makes a broadcast call to the lighting devices connected to it;

[0089] The lighting device responds to the broadcast call of the gateway and displays the style of the target image.

[0090] In some embodiments, the transmission between the gateway and the lighting device is carried out through BLE Bluetooth devices.

[0091] The following are specific embodiments of selecting a target image through the viewfinder area when the light-emitting units 110 in the light source assembly 100 are arranged in different ways.

[0092] Embodiment 1

[0093] As Figure 2 and Figure 3 shown, in this embodiment, the selected viewfinder area is a square, and the side length pixel of the viewfinder area is S.

[0094] The light-emitting units 110 in the light source assembly 100 are arranged in a ring. Specifically, the light source assembly 100 includes a light source substrate and a plurality of light-emitting basebands 120 each containing the same number of light-emitting units 110. The light source substrate is circular. The light source substrate includes a circular first part 130 located at the center of the light source substrate and a second part 140 surrounding the first part 130. The radius of the light source substrate is R1, the radius of the first part 130 is R2, and a plurality of light-emitting basebands 120 are all distributed on the second part 140. The number of light-emitting basebands 120 is M, and the average interval angle of each light-emitting baseband 120 is 360 / M. It is assumed that the light-emitting baseband 120 at the 3 o'clock direction is numbered 1; the light-emitting basebands 120 are numbered 1 to M counterclockwise; among them, the angle value of the light-emitting baseband 120 numbered Z is (360 / M)*(Z - 1); the length L (meter) of the light-emitting baseband 120 = R1 - R2; assuming there are e light-emitting units 110 per meter, and each light-emitting unit 110 is a control address, then the total number of control addresses on a single light-emitting baseband 120 is (R1 - R2)*e, and there are also (R1 - R2)*e pixel positions on the viewfinder area.

[0095] On the light source substrate, assume that the pixel value of all the light-emitting units 110 on the light source assembly 100 is r1 = R1 * e, and assume that the pixel value of all the control addresses on the second part 140 is r2 = R2 * e. The proportionality coefficient N of the virtual pixel points and the actual picture pixel points combined by the light-emitting baseband 120 is N = S / (R1 * 2 * e). The specific address t of the light-emitting unit 110 on the light-emitting baseband 120 to be obtained is as follows. (x0, y0) is the center coordinate value after the light-emitting baseband 120 is virtualized to the light-emitting unit 110, and this center coordinate value is (0, 0). The horizontal angle a between the currently obtained light-emitting baseband 120 with number z and the center is a = (360 / M) * (Z - 1). Then the control addresses x1, y1 of the light-emitting unit 110 at position t on the current light-emitting baseband 120 are:

[0096] x1 = x0 + (r2 + t - 1) * cos(a);

[0097] y1 = y0 + (r2 + t - 1) * sin(a);

[0098] The pixel position of the light-emitting unit 110 corresponding to the address t on the light-emitting baseband 120 with number z in the view-finding area is:

[0099] X1 = [x0 + (R2 * e + t - 1) * cos((360 / M) * (Z - 1))] * S / (R1 * 2e);

[0100] Y1 = [y0 + (R2 * e + t - 1) * sin((360 / M) * (Z - 1))] * S / (R1 * 2e);

[0101] The pixel information on the target image extracted at this pixel position is converted from the sRGB color space to the XYZ color space, and then the pixel information is converted from the XYZ color space to the Yxy color space. Among them, x and y in the Yxy color space are used as the color coordinates Cx, Cy of the corresponding light-emitting unit 110 (x1, y1) on the light-emitting baseband 120.

[0102] The Y value in the Yxy color space is the color brightness, which is an absolute value, not the dimming brightness ratio. Generally, the Y value cannot be directly used as the brightness of the light-emitting baseband 120. Here, the brightness output of 1% - 100% can be set according to actual needs in the lighting device. In some embodiments, the Y value is also sent to the lighting device, and the lighting device can use the brightness Y value as a reference.

[0103] Embodiment 2

[0104] In this embodiment, as Figure 4 (a) and Figure 4As shown in (b), when the light-emitting units 110 in the light source assembly 100 are arranged in a rectangular pattern, the selected viewing area is also rectangular. In this embodiment, the light-emitting units 110 are arranged in an 8×4 array, with a total of 32 control addresses. The numbers of the respective light-emitting units 110 are as shown in 4(b). The aspect ratio of the length and width of the light source assembly 100 is the same as that of the viewing area, and the viewing area also includes 32 pixel positions that correspond one-to-one with the control addresses of the light-emitting units.

[0105] After importing the target image into the viewing area, the pixel information at 32 pixel positions in the viewing area is extracted, and the pixel information at each pixel position is converted from the sRGB color space to the XYZ color space, and then the pixel information is converted from the XYZ color space to the Yxy color space. Among them, x and y in the Yxy color space are respectively used as the color coordinates Cx and Cy of the respective light-emitting units 110 corresponding to the pixel positions on the light-emitting baseband 120.

[0106] In some embodiments, the control terminal is connected to and transmits data to the lighting device through the cloud and the gateway. When transmitting through the gateway, because the data volume of the pixel information is relatively large and the data packet often exceeds 1k, the pixel information of each control address is transmitted from the control terminal to the lighting device through the cloud and the gateway in a sub-packet grouping manner. In some other embodiments, the control terminal can also directly transmit data to the lighting device through Bluetooth. The present invention does not limit the data transmission method.

[0107] In some embodiments, the lighting system includes several lighting devices. The control terminal is connected to multiple lighting devices through the cloud. After mapping the light source assembly 100 and the target image on the control terminal, the pixel information is used as the scene lighting parameter of the target image and sent to all lighting devices adapted to the target image. These lighting devices save the scene lighting parameter in a scene number. When calling later, the control terminal selects the target image, filters the lighting devices that can apply the target image in the cloud, and sends the call instruction to these lighting devices. The call instruction includes the scene number corresponding to the target image. After receiving the call instruction, the lighting device displays the style of the icon image corresponding to the scene number. Through this lighting system, the control of multiple lighting devices in the system can be conveniently and quickly realized.

[0108] The control terminal of the lighting system includes the APP on various devices and the panel in the lighting device, and calls each scene number through the APP or the panel.

[0109] Such as Figure 5As shown in the figure, it is a schematic flow chart of calling a lighting device through an APP. The user selects a target image on the APP side. After the cloud receives the instruction, it screens the gateways connected to the lighting devices that support the target image, sends an instruction to these gateways, and these gateways then broadcast and call all the lighting devices connected to them. The lighting devices that support the target image respond to the instruction, and the lighting devices send the scene lighting parameters in the scene number to each light-emitting unit, so that the lighting devices display the style of the corresponding target image.

[0110] As Figure 6 shown in the figure, it is a schematic flow chart of calling through the panel in the lighting device. After the panel selects a target image, the panel sends an instruction to the gateway connected to the lighting device through Bluetooth. After receiving the instruction, the gateway also sends the instruction to other gateways in the local area network. Each gateway analyzes the instruction through the automation engine and then broadcasts and calls the scene number corresponding to the target image to the lighting device. The lighting device responds to the instruction and displays the style of the corresponding target image.

[0111] In summary, for the lighting device control method of the present invention, by establishing a mapping relationship between the control addresses of each light-emitting unit 110 in the light source assembly 100 and the pixel positions in the target image, extracting the pixel information corresponding to each pixel position in the target image, and then sending the pixel information to the lighting device, the lighting device can control each light-emitting unit 110 to display the corresponding color according to the pixel information, so that the lighting device as a whole displays the style of the corresponding target image. The pixel information of multiple target images is saved in multiple scene numbers in the lighting device and can be quickly called through the APP or the panel in the lighting device later. The lighting system includes multiple lighting devices, and different lighting devices in the lighting system can be controlled to display different target images. The lighting system has stronger playability, and the display effect of the lighting device is more abundant. It can be applied to various occasions such as exhibition hall lighting layout, intelligent lighting display of home lighting equipment, and light shows for celebrations, meeting higher lighting requirements.

[0112] The above embodiments are only used to illustrate the technical solutions of the present invention and are not restrictive. Although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that the technical solutions of the present invention can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present invention.
