Wherein, the atmosphere light body refers to an atmosphere light system influencing the environment. The audio and video device refers to a device which has a wireless function and can play video data and audio data.
The video and audio equipment transmits the video data and the audio data corresponding to the video data to the receiving module through the network, and the processing module obtains the video data and the audio data corresponding to the video data from the receiving module. The processing module processes and extracts the video data to obtain image parameters, and the processing module processes and extracts the audio data to obtain sound parameters. For the receiving module, the video-audio lighting system can be set according to different use scenes and the existing equipment and the corresponding transformation cost. If the receiving module can obtain the image parameter and the sound parameter from the video equipment through a wireless connection mode such as Bluetooth and a local area network, and can also obtain the image parameter and the sound parameter from the video equipment through a wired connection mode. In particular, it is also possible to receive the image parameter and the sound parameter separately by a special receiving device, for example, an image receiver for identifying the image parameter is clamped on a panel for playing video data to obtain the image parameter, and a microphone is provided to receive the sound parameter. In addition, if the security monitoring camera is arranged, the security monitoring camera can be used as an image parameter and a sound parameter acquired by the receiving module for a panel which is placed at a fixed position and plays video data.
When a user uses the audio-visual equipment for entertainment, the user is influenced by audio-visual factors such as image parameters and sound parameters. Therefore, the main idea of the invention is to change the color temperature and the light intensity of the atmosphere light body through the control module according to the sound parameter and the image parameter, and simultaneously, the light system introduces the random number generator, generates the variation factor through the random number generator, and uses the variation factor as the interference, so that the control module can not follow the variation of the audio-visual factor at one step, and the visual fatigue of the user is avoided.

So that the light generated by the atmosphere light body accords with the feeling of the user.

the random number generator generates random positive integers;
the control module determines that the positive integer is an odd number, adjusts the color temperature of the atmosphere light body to a first color temperature, adjusts the color temperature of the atmosphere light body to a first light intensity, and sets the duration of the first color temperature and the first light intensity as a video frame set;
and when the control module determines that the positive integer is an even number, the color temperature of the atmosphere illuminant is adjusted to a second color temperature, the color temperature of the atmosphere illuminant is adjusted to a first light intensity, and the duration of maintaining the second color temperature and the first light intensity is a video frame set.
By the control mode, the control module can control the color temperature and the illumination of the atmosphere light body.
In some embodiments, the setting of the first relationship table, the second relationship table, the third relationship table, and the fourth relationship table may be customized according to the requirement of the user.

Specifically, assuming that the ambient light color temperature of the starting point of a sound segment of a certain song is 4700K and the preset fluctuation range is 1300K when the certain song is played, the allowed ambient light color temperature in the sound segment is [3400K,6000K ]. If the first color temperature or the second color temperature is less than 3400K, 3400K is selected; and if the first color temperature or the second color temperature is calculated to be larger than 6000K, taking 6000K.

The video-audio lighting system of claim 2, further comprising a storage module; establishing a mapping relation table between the main frequency and the color temperature of the atmosphere lamp light in advance, wherein the mapping relation table is a first relation table, and the first relation table is stored in a storage module; establishing a mapping relation table between the sound intensity and the light intensity of the atmosphere lamp light in advance, wherein the mapping relation table is a second relation table, and the second relation table is stored in a storage module; establishing a mapping relation table between the main color and the color temperature of the atmosphere lamp light in advance, wherein the mapping relation table is a third relation table, and storing the third relation table in a storage module; the control module determines to call the first relation table according to the received main frequency, so that a corresponding color temperature is found in the first relation table, and the corresponding color temperature is marked as a first color temperature; the control module determines to call a third relation table according to the received main color, so that a corresponding color temperature is found in the third relation table, and the corresponding color temperature is marked as a second color temperature; determining, at the control module, to call a second relation table according to the received sound intensity, so as to find a corresponding light intensity in the second relation table, wherein the corresponding light intensity is recorded as a first light intensity; the random number generator generates random positive integers; the control module determines that the positive integer is an odd number, adjusts the color temperature of the atmosphere light body to a first color temperature, adjusts the color temperature of the atmosphere light body to a first light intensity, and sets the duration of the first color temperature and the first light intensity as a video frame set; and when the control module determines that the positive integer is an even number, the color temperature of the atmosphere illuminant is adjusted to a second color temperature, the color temperature of the atmosphere illuminant is adjusted to a first light intensity, and the duration of maintaining the second color temperature and the first light intensity is a video frame set.
5. The video lighting system of claim 2, wherein the video frame set is a total playing duration of 30 video frames.
6. The video-audio lighting system of claim 1, wherein the ambience lighting comprises any one or more of a RGB light strip, a downlight, a spot light, or a bulb.
7. The video lighting system of any one of claims 1 to 6, wherein the receiving module is a wireless module.
8. The video-audio lighting system of claim 4, wherein the audio data is a song, the sound parameter further comprises a sound segment, and the processing module controls a fluctuation range of the color temperature of the ambience light body to be not more than a preset value range in the same sound segment based on the color temperature of the ambience light body at the start point of the sound segment.
