[0053] 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.

[0054] 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, while other details less related to the present invention are omitted.

[0055] In addition, it should also be noted that the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0056] The present invention provides a lighting system, and the lighting system will be described below with reference to specific embodiments.

[0057] The lighting system includes a control terminal and a lamp. An offset angle can be input through the control terminal. The control terminal communicates with the lamp through a communication module. The lamp is configured to provide illumination and can receive and respond to the angle information sent by the control terminal. In some other embodiments, other control information such as brightness and color temperature can also be input through the control terminal to adjust the brightness and color temperature of the lamp, and the present invention does not limit this.

[0058] As Figure 1 shown, the lighting system adjusts the color of the light displayed by the lamp through a lamp color adjustment method. The specific steps of the lamp color adjustment method are as follows:

[0059] Establish a coordinate mapping relationship between the color coordinates of the lamp and the polar coordinates on the color phase ring;

[0060] Obtain the initial polar coordinates according to the initial color coordinates and the coordinate mapping relationship;

[0061] Obtain the offset angle;

[0062] Based on the initial polar coordinates and the offset angle, form the target polar coordinates;

[0063] According to the target polar coordinates and the coordinate mapping relationship, obtain the target color coordinates corresponding to the target polar coordinates;

[0064] Adjust the color of the light emitted by the lamp based on the target color coordinates.

[0065] In the lamp color adjustment method of the present invention, a coordinate mapping relationship between the color coordinates in the color coordinate system and the polar coordinates on the color phase ring is established. The lamp maps the color of the light it currently emits from the initial color coordinates in the color coordinate system to the color phase ring to obtain the initial polar coordinates located on the color phase ring. An offset angle is input through the control terminal in the lighting system, and the control terminal will send the input offset angle to the lamp. The lamp adjusts the initial polar coordinates on the color phase ring according to the received offset angle, that is, the target polar coordinates in the adjusted color phase ring are obtained. Then, the target polar coordinates are inversely mapped to the color coordinate system to obtain the target color coordinates in the color coordinate system. According to the target color coordinates, the color of the light emitted by the lamp is changed from the color corresponding to the initial color coordinates to the color corresponding to the target color coordinates. This enables the color of the light of the lamp to be quickly adjusted, and the colors that the lamp can display are ever-changing, greatly enhancing the lighting scenarios that the lighting system can be applied to.

[0066] In the present invention, the lamp color adjustment method is based on the control address of the lamp to establish a mapping relationship between the color coordinates under the control address and the polar coordinates on the color phase ring, and, based on the control address, control the hue offset process of the lamp, where the hue offset process is defined as starting from obtaining the offset angle until the target color coordinates are obtained.

[0067] In some embodiments, when there is only one control address in the lamp, the color mixing method of the lamp includes:

[0068] Establish a mapping relationship between the color coordinates of the lamp under the control address and the polar coordinates on the hue ring;

[0069] Obtain the hue offset rotation angle of the lamp under the control address, and rotate the polar coordinates on the hue ring based on the offset angle to obtain the offset target polar coordinates;

[0070] Reverse map the target polar coordinates back to the color coordinate system of the lamp to obtain the target color coordinates of the lamp under the control address;

[0071] In some embodiments, when there are multiple control addresses in the lamp, the color mixing method of the lamp includes:

[0072] Establish a mapping relationship between the color coordinates of each control address and the polar coordinates on the hue ring;

[0073] Obtain the target color coordinates under all control addresses, and the obtaining method of any one of the target color coordinates includes:

[0074] Obtain the offset angle under a single control address, and adjust the polar coordinates on the hue ring based on the offset angle to obtain the offset target polar coordinates under the single address;

[0075] Reverse map the target polar coordinates back to the color coordinate system to obtain the target color coordinates under the control address;

[0076] Adjust the color of the lamp based on the target color coordinates under all control addresses.

[0077] The following combines Figure 2 , and specifically describes the conversion process between the color coordinates in the color coordinate system and the polar coordinates in the hue ring.

[0078] The initial color coordinates of the color displayed by the lamp initially in the color coordinate system are (x, y). Map the initial color coordinates (x, y) to the hue ring to obtain the initial polar coordinates in the hue ring as (r, θ). The offset angle sent by the control end is △θ. The lamp rotates the hue ring according to the received offset angle to obtain the target polar coordinates after rotation of the hue ring as (r, θ + △θ). Then reverse map the target polar coordinates (r, θ + △θ) to the color coordinate system to obtain the target color coordinates in the color coordinate system as (x', y'). The lamp can display the color corresponding to the target color coordinates (x', y') according to the target color coordinates (x', y').

[0079] In some embodiments, a lamp includes a plurality of lamp beads, and each lamp bead in the lamp has an independent control address. According to the offset angle, each control address obtains its corresponding target color coordinate through the lamp color mixing method. The color displayed by the lamp beads controlled by each control address is converted from the color corresponding to the polar coordinate before the rotation of the color wheel to the color corresponding to the target polar coordinate. That is, by only inputting a value of the offset angle from the control end, the colors of the lamp beads controlled by all the control addresses in the lamp will change, producing a kaleidoscopic color effect and bringing people a richer visual experience.

[0080] The control end in the lighting system includes an APP, a knob or a button. The user can input the value of the offset angle in various ways through the APP on the mobile device, or by rotating the knob of the lamp, and the angle of rotation of the knob is used as the offset angle, or the offset angle can be input through the button of the lamp. In some other embodiments, the offset angle can also be input in other ways, and the present invention does not limit this.

[0081] The input value of the offset angle is between 0 and 360 degrees, or can also be between -180 and 180 degrees, and is set according to the actual situation. The present invention does not limit this.

[0082] In some embodiments, the above APP, knob or button can also be used to adjust the color temperature and brightness of the lamp light, so as to further improve the controllability of the lighting system and enable the lighting system to meet the requirements of more scenarios.

[0083] The control end in the lighting system is connected to the lamp through a communication module. The communication module includes a Bluetooth module, a gateway or the cloud, which can be one of them, or a combination of two or three of them. In some other embodiments, communication can also be carried out through other communication methods, and the present invention does not limit this.

[0084] In some embodiments, when the communication module is a Bluetooth module, the control end communicates with the lamp through the Bluetooth module. The angle information input by the lamp is sent to the addresses of each control point in the lamp through the Bluetooth module. By using the Bluetooth module, the angle information input by the control end can be conveniently and quickly sent to the lamp, and the lamp can respond quickly.

[0085] In some embodiments, the lighting system includes several lamps, such as Figure 3As shown, the communication module at this time is a combination of the cloud and the gateway. The control end establishes communication with the cloud, and the cloud then establishes communication with several lamps through the gateway. The control end sends the data of the offset angle to the cloud. To save resources, the cloud will first perform screening to select the lamps that support the lighting adjustment function, and send a call instruction to the gateway that controls this part of the lamps. The gateway analyzes the offset angle through the automation engine and broadcasts it to all the lamps it controls. The broadcast message includes the offset angle, and the lamps in the gateway that support the lighting adjustment function will respond and change the displayed color according to the received offset angle.

[0086] In this way, the user can use the APP on the mobile device or the WEB on the computer as the control end, enabling remote control, and can more conveniently and quickly control several lamps in the lighting system to change information such as their lighting color, color temperature, and brightness, without being restricted by distance, making the application range of this lighting system wider.

[0087] In some embodiments, the lighting system includes several lamps, and at least one of the lamps is provided with a knob. Figure 4 As shown, the offset angle is adjusted by rotating the knob on one of the lamps. The lamp sends the offset angle to the gateway that communicates with it. The gateway will send the offset angle to other gateways within the local area network. Each gateway sends the offset angle to the lamps that communicate with it. The lamps that support the lighting adjustment function change the displayed color according to the offset angle. In some other embodiments, the lamp is provided with a control panel or buttons, and the offset angle can also be input through the control panel or buttons on the lamp. Similar to the knob, it also communicates through the gateway.

[0088] Using the physical knob / button on the lamp, the lamps located within the same local area network can be uniformly controlled, and all the lamps within the same local area network that support the lighting adjustment function can be controlled to change colors. The response speed is fast, enhancing the operability and playability of this lighting system and bringing a richer usage experience to users.

[0089] The lamp includes a control unit and a light-emitting module. The light-emitting module includes a plurality of light-emitting elements. The control unit receives the offset angle, calculates the color coordinates of each light-emitting element currently displayed in the light-emitting module in the color coordinate system, converts the color coordinates into polar coordinates in the hue ring, and performs a hue offset on the hue ring according to the offset angle to obtain the target polar coordinates. Then, the target polar coordinates are inversely mapped back to the color coordinate system to obtain the target color coordinates. The control unit then controls each light-emitting element in the light-emitting module to display the color corresponding to the target color coordinates. Through the control unit in the lamp, it can respond extremely quickly to the received offset angle, complete the above operations within one to two seconds, can respond extremely quickly to the user's operations, bring a good user experience, and meet the need for rapid color change of the light of the light-emitting module in actual use.

[0090] In summary, for the lamp color adjustment method of the present invention, the color coordinates of the currently displayed color are mapped onto the hue ring in the lamp to obtain the polar coordinates on the hue ring. By inputting the offset angle at the control end in the lighting system, the control end sends the offset angle to the lamp. The lamp rotates the hue ring according to the offset angle to obtain the target polar coordinates after the hue offset, and then inversely maps them to the color coordinate system to obtain the target color coordinates. The color of the lamp light is switched to the color corresponding to the target color coordinates. This enables the color of the lamp light to be quickly adjusted, can form an effect of ever-changing lamp colors, and greatly improves the lighting scenarios that the lighting system can apply.

[0091] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them. 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.
