The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0041] In the description of this application, "several" means more than one, "more" means more than two, "greater than", "less than", "exceed", etc. are understood to exclude the number itself, and "above", "below", "within", etc. are understood to include the number itself. If there is a description of "first" or "second", it is only used for the purpose of distinguishing technical features, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features or implicitly indicating the order of the indicated technical features.

[0042] In the description of the present application, the description with reference to the terms "one embodiment", "some embodiments", "illustrative embodiments", "examples", "specific examples", or "some examples" means that the specific features, structures, materials, or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials, or characteristics described may be combined in any one or more embodiments or examples in a suitable manner.

[0043] At present, with the development of LED lighting, LED light-emitting devices are widely used in different application scenarios. In different application scenarios, the color temperature, color, brightness and saturation of the scene are adjusted as needed.

[0044] However, the general LED lighting system is a passive "pan" lighting control, which is only applicable to general lighting application scenarios. For example, the user cannot effectively adjust the LED lighting system, so that the LED light output by the LED lighting system is not saturated enough.

[0045] For example, the LED lighting controller is controlled by wired or wireless Bluetooth, WIFI, etc. to actively control the LED lighting. However, since the user's regulation of the LED lighting controller is relatively subjective, the saturation of the LED lighting cannot effectively meet the needs of actual application scenarios.

[0046] Based on the above problems, the present application provides an LED lighting device, which adjusts the control parameters of the LED light source by automatically matching the scene image, thereby outputting high-saturation LED light to the application scene or the illuminated object, thereby providing a better lighting experience for the illuminated scene or the illuminated object.

[0047] Please refer to Figure 1 , Figure 2 The present application provides an LED lighting device, comprising: a first structural body 100, provided with a first cavity, the first cavity is used to accommodate a control circuit 200; wherein the first structural body is provided with a accommodating cavity in a circumferential direction; a second structural body 300, arranged corresponding to the first structural body, and forming a second cavity; a camera 400, arranged in the accommodating cavity; an LED lighting module 500, arranged in the second cavity, and connected to the control circuit; wherein the camera 400 is used to collect images of the current scene, and the LED lighting module 500 is also used to illuminate the current scene according to a control signal output by the control circuit.

[0048] As shown in the figure, the first structural body 100 is a hollow cylinder and is provided with a first cavity; a control circuit for controlling the LED lighting module 500 to perform lighting is provided in the first cavity. A receiving cavity is provided in the circumference of the first structural body, and the receiving cavity is used to accommodate the camera 400.

[0049] When the current scene is in a standard lighting state, the camera 400 acquires a scene image in the standard lighting state to obtain a scene image for color parameter extraction. The control circuit performs block color recognition on the scene image to obtain color parameters for characterizing the actual state of the current scene environment. The color parameters include at least one of hue, saturation, and brightness.

[0050] The control circuit traverses according to the color parameters and the pre-stored database to obtain the target lighting parameters, and drives and controls the LED lighting module according to the target lighting parameters.

[0051] The LED lighting device uses the color parameter as a feature quantity to traverse the database and obtain the target lighting parameter. The LED light source is driven and controlled according to the target lighting parameter, so as to adjust the ambient light of the application scene or the illuminated object. It can be understood that by adjusting the ambient light, the application scene or the illuminated object is placed in a high-saturation LED light, so that the illuminated scene or the illuminated object can have a better lighting effect.

[0052] The LED lighting module includes one or more white light LEDs, multiple color light LEDs, a secondary optical lens, and a structural heat sink for LEDs. The light generated by the white light LED or the color light LED is adjusted by the secondary optical lens to obtain a preset light field to obtain output light.

[0053] It can be understood that the LED light source includes a main light source and an auxiliary color gamut light source. If the matching result is a successful match, the output of the main light source is regulated by the first type of target lighting parameters, and the output of the auxiliary color gamut light source is regulated by the second type of target lighting parameters, so as to output a color temperature light with a full color gamut and high saturation. The main light source and the auxiliary color gamut light source work synchronously.

[0054] The main light sources are cool white LED light sources and warm white LED light sources, and the auxiliary color range light sources are red LED light sources, blue LED light sources, green LED light sources, and amber LED light sources.

[0055] In some embodiments, the LED lighting device further includes a third structural body 600, which is connected to the first structural body 100 and is used to fix the relative position of the control circuit 200 and the first structural body 100; wherein the third structural body 600 is provided with a through hole; and the electrical connector 700 is connected to the third structural body 600 and is electrically connected to the control circuit 200 via the through hole.

[0056] The third structural body is provided with a fixing column, and the control circuit is fixed by the fixing column to fix the relative position of the third structural body and the control circuit. The relative positions of the third structural body and the second structural body are fixed to fix the relative positions of the two. The electrical connector is electrically connected to the control circuit via a through hole, and the other end of the electrical connector is provided with a fixing member, which can be used to fix with an external object to fix the LED lighting device as a whole.

[0057] In some embodiments, the control circuit includes: a power supply drive circuit and a lighting control circuit; the power supply drive circuit includes: an AC / DC output power supply circuit, a DC / DC processor power supply circuit, and an LED control circuit; the lighting control circuit includes: an integrated processing circuit, a Bluetooth conversion circuit, a storage circuit, an over-temperature protection circuit, and a camera circuit; wherein the integrated processing circuit is used for image processing and PWM control.

[0058] The corresponding functional circuit is set to provide the appropriate voltage for the LED lighting device, and the external wireless signal is converted through the Bluetooth conversion circuit to achieve wireless control. The over-temperature protection circuit is used to protect the circuit to prevent the LED lighting device from overheating and circuit damage due to long-term operation.

[0059] In addition, in some embodiments, the current scene is photographed and recognized by the corresponding terminal to obtain a corresponding scene image. The scene image is processed by a processor provided inside the terminal to obtain corresponding color parameters. The corresponding target lighting parameters are transmitted to the LED lighting device through a Bluetooth conversion circuit.

[0060] For example, the terminal is a mobile phone, and the mobile phone is equipped with a corresponding LED lighting control program. The mobile phone is used to perform camera recognition of the current scene to obtain a corresponding scene image. After the mobile phone obtains the corresponding scene image, the LED lighting control program recognizes the scene image and obtains color parameters. The processor traverses the first mapping relationship stored in the database according to the color parameters and obtains the target lighting parameters. After the target lighting parameters are obtained through traversal and matching, the mobile phone sends the target lighting parameters to a specific LED lighting device, and adjusts the output of the main light source and the auxiliary color range light source according to the lighting drive parameters corresponding to the target lighting parameters.
