Specifically, acquire the actual colour temperature value of lamp source through the colour temperature illuminometer, compare actual colour temperature value and preset colour temperature value, preset colour temperature value for the light colour temperature value that the user actually wanted, promptly because some lamp pearls in the lamp source age and lead to the colour temperature to reach the requirement, wherein ageing lamp pearl can be for warm light lamp pearl also can be for cold light lamp pearl, promptly for probably not reaching preset warm light colour temperature or not reaching preset cold light colour temperature, preset colour temperature value by the user according to treating the setting of shining the thing, also can carry out corresponding setting by shining the scene, compare actual colour temperature value and preset colour temperature value.
102. And acquiring the compared color temperature difference value, and adjusting the color temperature of the light source according to the color temperature difference value.
Specifically, the actual color temperature value is compared with a preset color temperature value, so that a difference value is obtained, the difference value is input to the server, and the server adjusts the color temperature of the lamp source according to the difference value. Specifically, according to the difference between the actual color temperature value and the preset color temperature, determining how to adjust, for example, if a user needs to use a cold light lamp with a higher color temperature, and if the actual color temperature is lower than the preset color temperature, the color temperature of the light source needs to be increased; when a user needs to use a warm light with a low color temperature, the actual color temperature is higher than the preset color temperature, and the color temperature of the light source needs to be reduced.
103. And when the actual color temperature value is larger than the preset color temperature value, the PWM output power of the warm light lamp is gradually increased, and the actual color temperature value is reduced.
Specifically, when the actual color temperature value is greater than the preset color temperature value, the PWM output power of the warm light lamp is gradually increased. Wherein, through the duty cycle that changes warm light lamp pearl, it is specific, even through the PWM duty cycle that changes LED, its colour measurement is unchangeable and the corresponding linear type of photometric quantity changes, and the ratio of photometric quantity equals the ratio of duty cycle, and the duty cycle is the ratio of the time that the pulse occupies and total time in a section of continuous operation time. Wherein the photometric quantity may be luminous flux, illuminance, brightness or light intensity, and the colorimetric quantity may be chromaticity coordinates or correlated color temperature. Under the unchangeable condition of colour gamut volume, through changing the photometric quantity, make luminous flux, illuminance, luminance or the light intensity increase of part warm light lamp pearl to make warm light lamp pearl brighter, thereby make the colour temperature reduce, so that the colour temperature value is close to preset colour temperature value step by step.
It should be noted that, when the actual color temperature value is greater than the preset color temperature value, the PWM output power of the cold light lamp bead may also be reduced, so as to reduce the actual color temperature value, and the reduction manner is the same as that described above, and is not described herein again.

Concrete, when actual colour temperature value is less than predetermineeing the colour temperature value, the PWM output of step-by-step increase cold light lamp, specific increase mode is the same with in step 103, no longer gives unnecessary details here, wherein through the duty cycle of adjusting cold light lamp pearl, even luminous flux, illuminance, luminance or the light intensity increase of part cold light lamp pearl to make cold light lamp pearl brighter, thereby make the colour temperature increase. It is worth saying that the color temperature can be increased by reducing the duty ratio of the warm light bulb.
105. And stopping adjusting the PWM output power of the warm light lamp or the cold light lamp until the actual color temperature value is consistent with the preset color temperature value.
Specifically, because the duty ratio of warm light lamp pearl or cold light lamp pearl through changing, makes actual colour temperature change gradually, acquires the colour temperature value of light source in real time through the colour temperature illuminometer, when actual colour temperature value is unanimous with the colour temperature value of predetermineeing, stops the regulation to cold light lamp pearl or warm light lamp pearl promptly to make actual colour temperature unanimous with predetermineeing the colour temperature.

And adjusting the duty ratio of the warm color light bead or the cold color light bead according to the recommended color temperature, thereby realizing the adjustment of the color temperature.
Further, the identifying the image category includes:
preparing a preset number of sample images, and classifying the sample images;
training a recognition model by using the sample image;
and inputting the image of the object to be irradiated into the recognition model, and outputting a result according to classification.
Specifically, the server prepares a preset number of sample images, wherein the sample images are sofas, portraits, offices, hospitals and the like, are classified according to the sample images, the types are the corresponding sofas, portraits, offices, hospitals and the like, 1000 different sample images are prepared for each type of image for training, a recognition model is established, the recognition model is trained by utilizing the sample images, after the training is carried out for multiple times, the recognition result is continuously close to a real result, the image of the object to be irradiated is input into the recognition model, and the recognition result is output and is specifically the image type of the object to be irradiated.

Specifically, when the preset color temperature is set by the user, the historical preset color temperature is displayed in a form of a drop-down frame, and the historical color temperature data with the largest occurrence frequency is arranged at the front row, so that the user can quickly select the historical color temperature.
The implementation principle of the embodiment is as follows:
when the color temperature of the light emitted by the lamp source is not in accordance with the requirement due to the aging of one or some lamp beads, the color temperature value of the light emitted by the lamp source is obtained through a color temperature illuminometer, the obtained color temperature value is input into a system, the obtained color temperature value is compared with a preset color temperature value, the PWM output power of the warm light lamp bead or the cold light lamp bead is adjusted through a difference value, so that the actual color temperature value is continuously changed until the actual color temperature value is consistent with the preset color temperature value, the adjustment of the warm light lamp bead or the cold light lamp bead is stopped, the color temperature value of the actual light source is consistent with the color temperature value expected by a user, and the lamp outputs correct color temperature light;
