Therefore, the dimming stepping times can be changed according to the brightness change value of the lamp and the change of the dimming step, and are not limited herein specifically, where the direction of the dimming step may be a direction of increasing the brightness or a direction of decreasing the brightness, and are not limited herein specifically, and it needs to be described that the lamp can obtain the dimming step.
102. And determining the ratio of the total light gradual change duration to the dimming cycle duration as the number of dimming cycles.

103. If the ratio of the number of dimming cycles to the number of dimming steps is greater than or equal to 1, the dimming cycle of the number of dimming steps is selected as the target dimming cycle from among the dimming cycles of the number of dimming cycles.
And after the lamp determines the number of dimming cycles, determining the ratio of the number of dimming cycles to the number of dimming stepping times, and if the ratio is greater than or equal to 1, selecting the dimming cycles with the number of dimming stepping times from the dimming cycles with the number of dimming cycles as target dimming cycles. The target dimming period is used to indicate that the lamp adjusts the current brightness of the lamp according to the dimming step length in the target dimming period, specifically, after the dimming step length is applied on the basis of the current brightness according to the direction of the dimming step length, the new brightness may be changed to be bright or dark, for example, when the brightness gradually changes, the target is changed from bright to dark, or the brightness gradually changes, the target is changed from dark to bright.
104. And sequentially determining the dimming cycles of the dimming cycle number as the current dimming cycle.
And the lamp sequentially determines the dimming cycles of the number of the dimming cycles as the current dimming cycle.

when the brightness change value of the lamp is determined, the total time length of the gradual change of the light received by the lamp exceeds the total time length of the gradual change corresponding to the minimum precision, because the time length of the dimming cycle is fixed, the number of the dimming cycles determined according to the total time length of the gradual change of the light under the same dimming cycle time length is larger than the number of the dimming cycles determined according to the total time length of the gradual change corresponding to the minimum precision (the lamp can adjust the brightness in each dimming cycle of the total time length of the gradual change corresponding to the minimum precision), wherein, the number of the dimming cycles determined according to the total time length of the gradual change of the light corresponds to two parts, one part is that the brightness of the lamp is actually adjusted with the minimum precision, the other part is that the brightness of the lamp is maintained, and the lamp is actually adjusted with the minimum precision, the brightness of the lamp can be regarded as the dimming stepping number of the invention, and it can be seen that the, the brightness can also be adjusted, and the present embodiment illustrates how to maintain the brightness and adjust the brightness.
In the present embodiment, the lamp is adjusted based on the comparison result of i · Q-j and 1, where i denotes the number of dimming cycles, j denotes the number of dimming stepping times, Q denotes the ratio of the dimming stepping times to the dimming cycles, and Q ═ Lc/Sc, where Lc denotes the dimming stepping times, Sc denotes the dimming cycles, and the interval of Q is (0, 1).
301. Determining a first dimming cycle of the number of dimming cycles as a current dimming cycle, and determining a first dimming step of the number of dimming steps as a current dimming step.
After the lamp determines the number of dimming cycles and the number of dimming steps, the lamp determines a current dimming cycle from a first dimming cycle of the number of dimming cycles, and determines a current dimming step from a first dimming step of the number of dimming steps.
302. The sequence number of the current dimming cycle is determined to be 1, and the sequence number of the current dimming step is determined to be 0.
After the lamp determines the current dimming cycle and the current dimming step, the lamp determines that the serial number of the current dimming cycle is 1, and determines that the current dimming step is 0.

And if the serial number of the current dimming stepping is less than or equal to the number of the dimming cycles and the difference value is less than 1, determining that the current dimming cycle is a non-target dimming cycle, adding 1 to the serial number of the current dimming cycle, and returning to the step of calculating the difference value between the product of the serial number of the current dimming cycle and the ratio and the serial number of the current dimming stepping times.
If the lamp determines that the calculated difference is less than 1 and the serial number of the current dimming step is less than or equal to the number of dimming cycles, the current dimming cycle is determined to be a non-target dimming cycle, then the serial number of the current dimming cycle is added by 1, and finally the step of calculating the difference between the product of the serial number of the current dimming cycle and the ratio and the serial number of the current dimming step number is returned, that is, the step 304 is returned to.
In this embodiment, the lamp can adjust the brightness in a more uniform dispersion manner in the total gradual change duration of the light through the steps of this embodiment. For Q in the interval (0, 1) and the value 1, integer multiples [1/Q ] exist, after a step length of Q for every step length of [1/Q ] +1 times, namely ([1/Q ] +1) Q, the value is greater than 1, namely for Q in the interval (0, 1), for every adjustment from 1 to [1/Q ] times or [1/Q ] +1 times, there is an approximation centered on the value 1, or for every adjustment from 1 to [1/Q ] times or [1/Q ] +1 times, as a periodic regression with the value 1, based on this mathematical phenomenon, the invention adjusts brightness using a comparison of the magnitude of i.Q-j with 1, where i is sequentially incremented by integers, causing i.Q to increase successively, in order to enable the changing i.Q to exhibit this mathematical phenomenon, therefore, the i and Q which are gradually increased are corrected, namely j which is increased by the same integer according to the condition is subtracted, so that the distance between the i, Q and j and the value 1 has the variation of the similar period, wherein the variation of the j indicates the beginning of another cycle of the mathematical phenomenon and indicates the other action of the brightness adjustment of the lamp, and the action of the brightness adjustment can be uniformly and dispersedly executed in the total time length of the gradual change of the whole lamp.
