In one possible implementation, the preset date is the current date, for example, if the current date is 2021 year 2 month 1 day, then the preset date is also 2021 year 2 month 1 day. That is, sunrise time and sunset time of the preset geographical location (for example, the location where the lamp is located) on 2/1/2021 are obtained.

Specifically, the corresponding relation between the daylight color temperature and the time is determined according to the first color temperature, the second color temperature, the third color temperature, the corresponding acquisition time of the first color temperature, the corresponding acquisition time of the second color temperature, and the corresponding acquisition time of the third color temperature. In order to improve the accuracy of the determined correspondence between the daylight color temperatures and the time, the number of the collected daylight color temperatures can be increased, and the correspondence between the daylight color temperatures and the time is determined according to all the collected daylight color temperatures and the corresponding collection time.
And after the corresponding relation between the daylight color temperature and the time is determined, determining the color temperature corresponding to each time node of the lamp according to the corresponding relation between the daylight color temperature and the time node for adjusting the color temperature of the lamp. In a possible implementation manner, time nodes between the collection time of the first color temperature and the collection time of the third color temperature, that is, time nodes of daylight color temperature change are determined according to the number of the time nodes, and the daylight color temperature corresponding to each time node of daylight color temperature change is determined according to the time nodes of daylight color temperature change and a relation between the daylight color temperature and time. And according to the sequence of the time nodes, the time nodes for adjusting the color temperature of the lamp are in one-to-one correspondence with the time nodes for changing the color temperature of the daylight, and the color temperature of the time nodes for changing the color temperature of the daylight is used as the color temperature of the time nodes for correspondingly adjusting the color temperature of the lamp. In another possible implementation manner, the correspondence between the daylight color temperature and the time may also be modified according to the sunrise time and the sunset time to obtain a modified correspondence between the daylight color temperature and the time, and the time node for adjusting the color temperature of the lamp is substituted into the modified correspondence between the daylight color temperature and the time to obtain the color temperature corresponding to each time node for adjusting the color temperature of the lamp.
After the color temperature corresponding to each time node for adjusting the color temperature of the lamp is determined, the relation between the color temperature of the lamp and the time can be determined, namely the color temperature change curve of the lamp, and the color temperature change information is consistent with the color temperature change curve, so that the color temperature of the lamp is changed in a gradual change mode, and the accuracy of simulating the color temperature of sunlight is improved. In another possible implementation manner, the color temperature of the lamp may also be instantaneously changed to the color temperature of the corresponding time node at each time node according to the color temperature corresponding to each time node for adjusting the color temperature of the lamp.

The first and second light emitting units may each be an LED lamp. The color temperature of the first light-emitting unit is different from that of the second light-emitting unit, the first light-emitting unit and the second light-emitting unit correspond to different current output channels, and the proportion of the first input current to the second input current is current proportion. In a possible implementation manner, one of the first light emitting unit and the second light emitting unit has a color temperature lower than the lowest color temperature of sunlight, and the other has a color temperature higher than the highest color temperature of sunlight, and the first light emitting unit and the second light emitting unit emit light simultaneously, and the range of change of the color temperature of the synthesized light can satisfy the color temperature change information consistent with the change of the color temperature of sunlight.

The corresponding relation between the color temperature of the lamp and the current ratio is determined according to experimental data obtained by testing the lamp in advance. The simulated sunlight can be emitted through the two light-emitting units, and the manufacturing cost of the lamp is reduced.
In one possible implementation, the current ratio is the ratio I of the current of one of the output channels to the total current f Indicating, for example, that the current ratio is expressed in terms of the ratio of the first input current to the sum of the first input current and the second input current. The relationship between the color temperature and the current ratio of the lamp can be expressed as a first relationship CCT ═ f (I) f ) And the relation between the daylight color temperature and the time is a second relation CCT (f (t'), and a third relation I between the current ratio and the time can be obtained according to the first relation and the second relation when the daylight color temperature of the lamp is simulated and collected and the daylight color temperature of the day is luminous f F (t'), wherein the first, second, and third relationships may each be polynomial equations. And according to a third relation between the current ratio and the time node of the sunlight color temperature change, determining the current ratio corresponding to the time node of the sunlight color temperature change. And according to the sequence of the time nodes, the time nodes for adjusting the color temperature of the lamp are in one-to-one correspondence with the time nodes for changing the daylight color temperature, and the current proportion of the time nodes for changing the daylight color temperature is used as the current proportion of the time nodes for correspondingly adjusting the color temperature of the lamp. According to the time node for adjusting the color temperature of the lamp and the corresponding current ratio, the relation between the current ratio and the time of the lamp on the preset date can be determined, and according to the preset current ratio of the lampThe relation between the current ratio of the date and the time controls the first light-emitting unit and the second light-emitting unit to emit light.
In another possible implementation manner, the lamp may also include a plurality of light-emitting units, each light-emitting unit corresponds to one color temperature, and the corresponding lamp is controlled to emit light according to the color temperature corresponding to each time node, so that the lamp emits light according to the corresponding color temperature at each time node.

Since the color temperature change information is determined according to the color temperature of the sunlight collected in advance, the color temperature change information from the sunrise time to the sunset time is consistent with the change situation of the color temperature of the sunlight, and therefore the lamp is controlled to emit light according to the color temperature change information to simulate the color temperature change of the sunlight. And the lamp can simulate the change condition of the color temperature of the sunlight on the local day along with the change of the geographical position, and is beneficial to regulating the physiological rhythm of the personnel working indoors for a long time by simulating the change of the color temperature of the sunlight.
