[0056] In order to make the objectives, technical solutions and advantages of this application clearer, this application is described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] It should be noted here that in order to avoid obscuring the present application due to unnecessary details, only the structures and / or processing steps closely related to the scheme of the present application are shown in the accompanying drawings, while other details that are not closely related to the present application are omitted.

[0058] In addition, it should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also includes other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0059] The present application provides a lighting system, which is described below with reference to specific embodiments.

[0060] The lighting system includes a control terminal and several lighting devices. The lighting device includes at least one light source assembly, which includes multiple light-emitting units. Each light-emitting unit has an independent control address and can be controlled by the following lighting device control method:

[0061] Selecting a framing area, where the framing area has a number of pixel positions;

[0062] Establishing a first position mapping relationship between a control address of each light-emitting unit in the light source assembly and a pixel position of a framing area;

[0063] Importing a target image into the framing area so that the target image has a certain pixel position;

[0064] Establishing a second position mapping relationship between pixel positions of the target image and pixel positions of the framing area;

[0065] Based on the first position mapping relationship and the second position mapping relationship, pixel information at the pixel position of the target image corresponding to the pixel position of the framing area is extracted, and the pixel position of the framing area and the extracted pixel information in the target image corresponding to the pixel position are sent to the lighting device.

[0066] The color of the light emitted by each light-emitting unit is adjusted based on the pixel information of the target image and the pixel position of the framing area, so that the lighting device displays the style of the target image.

[0067] As shown in Figure 1, in the lighting system of the present application, the lighting device controls each light-emitting unit to emit light of the color corresponding to the pixel information based on the pixel position of the framing area and the pixel information corresponding to the pixel position of the extracted target image. The lighting device as a whole displays the style corresponding to the target image, and the display style is more diversified.

[0068] In this embodiment, the pixel information specifically includes color coordinate information. The control end sends the color coordinate information of each control address to the lighting device. The lighting device controls the light-emitting units of each control address to display the corresponding color according to the color coordinates, and the brightness value is set between 1% and 100% as needed.

[0069] After the target image is imported into the framing area, the size of the pixel size of the target image and the pixel size of the framing area is first determined. When the pixel size of the target image is larger than the pixel size of the framing area, the pixel size of the target image is reduced to fit the pixel size of the framing area, and a second position mapping relationship between the pixel position of the reduced target image and the pixel position of the framing area is established; alternatively, the target image is directly imported into the framing area, and only the second position mapping relationship between the pixel position of the target image that matches the pixel size of the framing area and the pixel position of the framing area is established.

[0070] When the pixel size of the target image is smaller than the pixel size of the framing area, the pixel size of the target image is enlarged to fill the framing area, and a second position mapping relationship between the pixel positions of the enlarged target image and the pixel positions of the framing area is established; alternatively, the target image is directly imported into the framing area, and only the second position mapping relationship between the pixel positions of the framing area that matches the pixel size of the target image is established. In this case, the second mapping relationship is not established between some pixel positions in the framing area and the pixel positions of the target image, and these pixel positions in the framing area are directly assigned pixel information of a preset background color.

[0071] In this embodiment, the pixel size of the framing area is less than or equal to 1000*1000.

[0072] The framing area includes any one of a square framing area, a rectangular framing area and a circular framing area. When the framing area is a square or a circular framing area, the target image imported into the framing area is a square; when the framing area is a rectangle, the target image imported into the framing area is a rectangle.

[0073] In some other embodiments, the pixel information also includes brightness information. As shown in Figure 5, the control end packages the color coordinate information, brightness information and pixel information together and sends them to the lighting device. Bright in Figure 5 is the brightness information, Cx and Cy are the color coordinate information, and the lighting device uses the received brightness information as a reference value to set the brightness displayed by the lighting device.

[0074] In some embodiments, the light source assembly 100 includes several light-emitting base strips 120, each light-emitting base strip 120 includes a plurality of light-emitting units 110 of the same number, and the arrangement of the light-emitting base strips 120 includes horizontal arrangement, vertical arrangement and circular arrangement.

[0075] The control end packages the converted pixel information of each control address, including color coordinates, brightness information and pixel position, 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 is only necessary to call different scene numbers through the control end, making the entire control process more convenient and quick.

[0076] As shown in FIG6 , in some embodiments, the control terminal may be an APP on various mobile devices, and a user may remotely control the lighting device to adjust the lighting device through the APP, specifically including the following steps:

[0077] Select the target image through the APP;

[0078] The APP sends a command to the cloud to call the target image;

[0079] The cloud screens the lighting devices that are compatible with the target image and sends a command to the gateway connected to these lighting devices to call the scene number corresponding to the target image;

[0080] Each gateway broadcasts the scene number to the lighting devices connected to it;

[0081] The lighting device adapted to the target image responds to the broadcast call of the gateway and displays the style of the target image.

[0082] As shown in FIG7 , in some embodiments, the control end may be a panel in the lighting device, and the steps of controlling the lighting device to adjust through the panel specifically include:

[0083] Select the target image through the panel;

[0084] The panel sends a command to the gateway to call the scene number corresponding to the target image;

[0085] The gateway parses the instruction through the engine and sends the instruction of calling the scene number to other gateways in the local area network;

[0086] Each gateway broadcasts and calls the lighting devices connected to it;

[0087] The lighting fixtures respond to the gateway's broadcast call and display the style of the target image.

[0088] In some embodiments, transmission between the gateway and the lighting device is performed via a BLE Bluetooth device.

[0089] The following is a specific embodiment of selecting a target image through a framing area when the light emitting units 110 in the light source assembly 100 are arranged in different ways.

[0090] Example 1

[0091] As shown in FIG. 2 and FIG. 3 , in this embodiment, the selected framing area is a square, and the side length of the framing area is S pixels.

[0092] 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 base strips 120 including the same number of light emitting units 110. The light source substrate is circular and includes a first portion 130 located in the center of the light source substrate and a second portion 140 surrounding the first portion 130. The radius of the light source substrate is R1, and the radius of the first portion 130 is R2. The plurality of light emitting base strips 120 are distributed on the second portion 140. The number of the light emitting base strips 120 is M, and each light emitting base strip 120 is M. The average interval angle of 0 is 360 / M, and the light-emitting baseband 120 at the 3 o'clock direction is numbered 1; the light-emitting baseband 120 is 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 is R1-R2; assuming that there are e light-emitting units 110 per meter, and each light-emitting unit 110 is a control address, there are a total of (R1-R2)*e control addresses on a single light-emitting baseband 120, and there are also (R1-R2)*e pixel positions on the framing area.

[0093] On the light source substrate, assuming that the pixel values ​​of all the light-emitting units 110 on the light source assembly 100 are r1=R1*e, assuming that the pixel values ​​of all the control addresses on the second part 140 are r2=R2*e, the ratio coefficient of the virtual pixel points and the actual image pixel points of the light-emitting baseband 120 is N, N=S / (R1*2*e), the specific address of the light-emitting unit 110 on the light-emitting baseband 120 is t, (x0, y0) is the center coordinate value of the circle after the light-emitting baseband 120 is virtualized to the light-emitting unit 110, and the center coordinate value is (0, 0). The horizontal angle between the light-emitting baseband 120 with the number z and the center of the circle is a=(360 / M)*(Z-1), then the control addresses x1 and y1 of the light-emitting unit 110 at position t on the current light-emitting baseband 120 are: x1=x0+(r2+t-1)*cos(a); y1=y0+(r2+t-1)*sin(a);

[0094] The pixel position of the light-emitting unit 110 at address t on the light-emitting baseband 120 numbered z in the framing area is: X1 = [x0 + (R2*e + t-1) * cos ((360 / M) * (Z-1))] * S / (R1*2e); Y1 = [y0 + (R2*e + t-1) * sin ((360 / M) * (Z-1))] * S / (R1*2e);

[0095] The pixel information of the target image extracted at the 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, where x and y in the Yxy color space are respectively used as the color coordinates Cx and Cy of the corresponding light-emitting unit 110 (x1, y1) on the light-emitting baseband 120.

[0096] The Y value in the Yxy color space represents the color brightness, an absolute value, not a dimming brightness ratio. Generally, the Y value cannot be directly used as the brightness of the light-emitting baseband 120. Instead, the lighting device can set the brightness output between 1% and 100% based on actual needs. In some embodiments, the Y value is also sent to the lighting device, which can use the brightness Y value as a reference.

[0097] Example 2

[0098] In this embodiment, as shown in Figures 4(a) and 4(b), when the light-emitting units 110 in the light source assembly 100 are arranged in a rectangular shape, the selected framing 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, and the numbering of each light-emitting unit 110 is shown in Figure 4(b). The aspect ratio of the light source assembly 100 is consistent with that of the framing area, and the framing area also includes 32 pixel positions that correspond one-to-one to the control addresses of the light-emitting units.

[0099] After the target image is imported into the framing area, the pixel information of the 32 pixel positions in the framing area is extracted, and the pixel information of 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, where x and y in the Yxy color space are respectively used as the color coordinates Cx and Cy of each light-emitting unit 110 corresponding to the pixel position on the light-emitting baseband 120.

[0100] In some embodiments, the control terminal connects to the lighting device via the cloud and a gateway for transmission. When transmitting through the gateway, the pixel information is large, often exceeding 1KB in size. Therefore, a packet-by-packet approach is used to sequentially transmit pixel information for each control address from the control terminal to the lighting device via the cloud and the gateway. In other embodiments, the control terminal may also directly transmit data to the lighting device via Bluetooth. This application does not restrict the data transmission method.

[0101] In some embodiments, the lighting system includes several lighting devices, and the control end is connected to the multiple lighting devices through the cloud. After completing the mapping of the light source assembly 100 and the target image on the control end, the pixel information is used as the scene lighting parameters of the target image and sent to all lighting devices adapted to the target image. These lighting devices save the scene lighting parameters to a scene number. During subsequent calls, the target image is selected through the control end, and the lighting devices that can apply the target image are screened in the cloud, and the call instruction is sent 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 achieved conveniently and quickly.

[0102] The control end of the lighting system includes APPs on various devices and panels in the lighting fixtures, and each scene number is called on the APP or panel.

[0103] As shown in Figure 5, this is a flow chart of calling a lighting device through an APP. The user selects a target image on the APP side. After receiving the instruction, the cloud screens the gateways connected to the lighting devices that support the target image and sends instructions to these gateways. These gateways then broadcast the call to all 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.

[0104] As shown in Figure 6, this is a flow chart of calling through the panel in the lighting device. After the panel selects the target image, the panel sends a command to the gateway connected to the lighting device via Bluetooth. After receiving the command, the gateway also sends the command to other gateways in the local area network. Each gateway parses the command through the automation engine and then broadcasts the scene number corresponding to the target image to the lighting device. The lighting device responds to the command and displays the style of the corresponding target image.

[0105] To sum up, the lighting device control method of the present application establishes a mapping relationship between the control address of each light-emitting unit 110 in the light source assembly 100 and the pixel position in the target image, extracts the pixel information corresponding to each pixel position in the target image, and then sends 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 to multiple scene numbers in the lighting device, which can be quickly called later through the APP or the panel in the lighting device. 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 is more playable and the lighting device display effects are richer. It can be applied to exhibition hall lighting layout, smart lighting display of home lighting equipment, light shows for celebrations and other occasions to meet higher lighting needs.

[0106] The above embodiments are only used to illustrate the technical solutions of the present application and are not intended to limit the present application. Although the present application has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that the technical solutions of the present application may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
