[0066] In the application, the lamp color adjusting method establishes a mapping relationship between the color coordinates under the control address and the polar coordinates on the hue circle based on the control address of the lamp, and controls the hue offset process of the lamp based on the control address, wherein the hue offset process is defined as from obtaining the offset angle to obtaining the target color coordinate.

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

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

[0069] obtaining a hue offset rotation angle of the lamp under the control address, and rotating the polar coordinates on the hue circle based on the offset angle to obtain a target polar coordinate after offset;

[0073] obtaining target color coordinates under all control addresses, and the obtaining method of any target color coordinate comprises:

[0077] The conversion process between the color coordinates in the color coordinate system and the polar coordinates in the hue circle will be described in detail below. Figure 2

[0078] The initial color coordinates of the color displayed by the lamp in the color coordinate system are (x, y), the initial polar coordinates in the hue circle obtained by mapping the initial color coordinates (x, y) to the hue circle are (r, θ), the offset angle sent by the control end is Δθ, the lamp rotates the hue circle according to the received offset angle to obtain the target polar coordinates of the hue circle after rotation (r, θ+Δθ), and the target polar coordinates (r, θ+Δθ) are mapped back to the color coordinate system in reverse to obtain the target color coordinates (x’, y’) in the color coordinate system. 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, the lamp includes a plurality of lamp beads, each of the lamp beads in the lamp has an independent control address, and each control address obtains a corresponding target color coordinate through the lamp color adjusting method according to the offset angle. The color displayed by the lamp bead controlled by each control address is converted from the color corresponding to the polar coordinate before the color phase ring is rotated to the color corresponding to the target polar coordinate. That is, only one value of the offset angle needs to be input from the control end, and the color of all the lamp beads controlled by the control addresses in the lamp will change, producing a color-changing effect and bringing people a more rich 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 through the APP on the mobile device in multiple ways, or rotate the knob of the lamp, and the angle of rotation of the knob is used as the offset angle. The offset angle can also be input through the button of the lamp. In other embodiments, the offset angle can also be input in other ways, which are not limited by the present application.

[0081] The value of the input offset angle is between 0 and 360 degrees, or between -180 and 180 degrees, which is set according to the actual situation, and the present application is not limited thereto.

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

[0083] The control end in the lighting system is connected with the lamp through a communication module, which includes a Bluetooth module, a gateway or a cloud, and can be one of them or a combination of two or three of them. In other embodiments, other communication methods can also be used for communication, which are not limited by the present application.

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

[0085] In some embodiments, the lighting system includes a plurality of 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 establishes communication with a plurality of lamps through the gateway. The control end sends the offset angle data to the cloud. In order to save resources, the cloud first performs screening on the lamps supporting light adjustment function, and sends a calling instruction to the gateway controlling the lamps. The gateway parses the offset angle through the automation engine, and broadcasts the offset angle to all the lamps controlled by the gateway. The lamps supporting light adjustment function in the gateway respond to the broadcast message 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 to remotely control the lamps in the lighting system to change the color, color temperature, brightness, etc. of the lighting, which is more convenient and fast, and makes the application range of the lighting system wider.

[0087] In some embodiments, the lighting system includes a plurality of lamps, at least one of which 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 in communication with it. The gateway sends the offset angle to other gateways in the local area network. Each gateway sends the offset angle to the lamps in communication with it. The lamps supporting light adjustment function change the displayed color according to the offset angle. In other embodiments, the lamps are provided with control panels or keys, and the offset angle can also be input through the control panels or keys on the lamps. Like the knob, the communication is also through the gateway.

[0088] The physical knob / case on the lamp can be used to uniformly control the lamps in the same local area network, and the lamps supporting light adjustment function in the same local area network can change color at a corresponding speed, which enhances the operability and playability of the lighting system and provides users with a richer use experience.

[0089] The lamp includes a control unit and a light-emitting module, the light-emitting module includes a plurality of light-emitting pieces, the control unit receives an offset angle, the control unit calculates the color coordinates of the color currently displayed by each light-emitting piece in the color coordinate system, converts the color coordinates into polar coordinates in the color circle, offsets the hue in the color circle according to the offset angle, obtains target polar coordinates, maps the target polar coordinates back to the color coordinate system to obtain target color coordinates, and controls each light-emitting piece in the light-emitting module to display the color corresponding to the target color coordinates according to the target color coordinates. The control unit in the lamp can quickly respond to the received offset angle, complete the above operations within one to two seconds, quickly respond to the user's operation, bring good user experience, and meet the need for quickly changing the color of the light of the light-emitting module in actual use.

[0090] In summary, the lamp color adjusting method of the present application maps the color coordinates of the color currently displayed to the color circle to obtain polar coordinates on the color circle, inputs an offset angle in the control end of the lighting system, the control end sends the offset angle to the lamp, the lamp rotates the color circle according to the offset angle to obtain target polar coordinates after hue offset, maps the target polar coordinates back to the color coordinate system to obtain target color coordinates, and switches the color of the light of the lamp to the color corresponding to the target color coordinates. The color of the light displayed by the lamp can be quickly adjusted, the effect of changing the color of the light can be formed, and the lighting scenes that can be applied by the lighting system are greatly improved.
