If it is determined that it is not daytime, the brightness sensing control module 11 continues to time the night time value TL_temp (S27). Only the brightness sensing control module 11 counts the night time value TL_temp.

When the brightness sensing control module 11 generates the night entry command, it means nighttime. When the above steps are executed to the step of "execute an initial program by the brightness sensing control module 11 to calculate the initial ambient brightness value (S21)", As shown in Figure 4, the method further includes the following steps:

The brightness sensing control module 11 provides a daytime brightness reference value and a nighttime timing reference value (S211);

The brightness sensing control module 11 detects an initial ambient brightness value (S212);

The brightness sensing control module 11 determines whether the initial ambient brightness value is less than the daytime brightness reference value (S213);

If so, the brightness sensing control module 11 generates the night entry command (S214);

If not, the brightness sensing control module 11 resets the night time value TL_temp to zero (S215); when the brightness sensing control module 11 compares the initial ambient brightness value to be less than the daytime brightness reference value, it determines that it is night time, and The night entry command is generated. If the initial ambient brightness value is greater than the daytime brightness reference value, it is judged that nighttime has not entered, and the night time value TL_temp is reset to zero to avoid timing the night time value TL_temp during the day; the night timing reference value is used for Compare with the night time value TL_temp to determine whether the night time value TL_temp is normally timed; when the execution goes to step (S25), when the brightness sensing control module 11 determines that the first ambient brightness value is greater than the daytime brightness reference value, Then it is judged that it is daytime; the daytime brightness reference value and the nighttime timing reference value are set by the user, and after setting, they do not need to be set again until the user resets them.

When the above steps are executed to "if the night entry command is generated, the brightness sensing control module 11 starts to count a night time value TL_temp, and drives the power module 12 to control the light emitting module 13 to automatically adjust at different adjustment times at night.

The brightness sensing control module 11 determines whether there is a night average TL (S231);

If the brightness sensing control module 11 determines that the night average value TL is absent, the brightness sensing control module 11 drives the power supply module 12 to control the light emitting module 13 to emit light with high brightness all night (S232);

If the brightness sensing control module 11 determines that there is the night average value TL, the light emitting module 13 emits light with high brightness, and sets a first adjustment time H1 and a second adjustment time H2 (S233);

The brightness sensing control module 11 determines whether the time reaches the first adjustment time H1 (S234);

If the brightness sensing control module 11 determines that the time has not reached the first adjustment time H1, the light emitting module 13 continues to emit light with high brightness (S235);

If the brightness sensing control module 11 determines that the time reaches the first adjustment time H1, it controls the light-emitting module 13 to adjust to low-brightness lighting (S236);

The brightness sensing control module 11 determines whether the time reaches the second adjustment time H2 (S237);

If the brightness sensing control module 11 determines that the time has not reached the second adjustment time H2, the light emitting module 13 continues to emit light at low brightness (S238);

If the brightness sensing control module 11 determines that the time reaches the second adjustment time H2, it controls the light-emitting module 13 to adjust to high-brightness lighting (S239); by judging whether the night average value TL exists, it can be confirmed whether the lamp body 10 is It is the first startup or has been used, but the night time value TL_temp is not properly timed. If there is no night average TL, the light-emitting module 13 emits light with high brightness throughout the night; if there is the night average TL, it means that the When the lamp body 10 has been used for at least one night, the light emitting module 13 automatically adjusts the brightness at the first adjustment time H1 and the second adjustment time H2, so that the lamp body 10 automatically adjusts the brightness in the middle of the night when there are fewer people.

Further, when the above steps are executed to "if it is determined to be daytime, the brightness sensing control module 11 stops timing the night time value TL_temp, and generates a midnight time VM and the next night adjustment time of the next night (S26)", as shown in FIG. 6 . As shown, the method further includes the following steps:

The brightness sensing control module 11 stops timing the night time value TL_temp, and drives the power module 12 to control the light-emitting module 13 to turn off (S261);

The brightness sensing control module 11 determines whether the night time value TL_temp is greater than the night time timing reference value (S262);

If the brightness sensing control module 11 determines that the night time value TL_temp is greater than the night time timing reference value, the night time value TL_temp is stored (S263);

The brightness sensing control module 11 executes a time calculation program to generate the midnight time VM of the next night (S264);

The brightness sensing control module 11 executes a time setting procedure to generate the first adjustment time H1 and the second adjustment time H2 for the next night (S265); in this embodiment, when the night time value TL_temp is greater than the night time The timing reference value is valid timing; when the night time value TL_temp is smaller than the night timing reference value, the night time value TL_temp is not stored.

When the above steps are executed to the step of “the brightness sensing control module 11 executes a time calculation program to generate the midnight time VM of the next night (S264)”, as shown in FIG. 7 , the method further includes the following steps:

The average of the night time values TL_temp until the accumulated number of night time values TL_temp reaches a maximum number, and the subsequent calculations are performed with the maximum number of night time values TL_temp; for example, the maximum number of night time values TL_temp is four nights;

The brightness sensing control module 11 calculates the midnight time VM of the next night; in this embodiment, the midnight time VM is the middle value of the night average TL, that is, the midnight time VM=the night average TL divided by 2 (S2642); The brightness sensing control module 11 stores the midnight time VM and the night average TL (S2643).

In this embodiment, the night time value TL_temp does not exist if it is used for the first time, so the night average value TL is not calculated. When the second night has the night time value TL_temp of the first night, the night time value TL_temp of the first night is used to calculate the night average TL, and then the night average TL calculated from the first night is used to calculate the second night time value TL_temp. This midnight time VM of the night. When the fifth night is the night time value TL_temp of the previous four nights, the night time value TL_temp of the previous four nights is used to calculate the average TL of the night, and the average TL of the night calculated from the previous four nights is used to calculate the time value of the fifth night. The midnight time VM. On the sixth night, and the night time value TL_temp of the fifth night is less than the night timing reference value, it is not stored, and the night time value TL_temp of the first to fourth nights is still used to calculate the night average TL for the sixth night. , and calculate the midnight time VM of the sixth night based on the night average TL calculated from the first to fourth nights. On the seventh night, the night time value TL_temp of the second to fourth night and the sixth night will be used to calculate the night average TL, and then the night average TL calculated from the second to fourth night and the sixth night will be used. Calculate the midnight time VM of the seventh night, thereby correcting the midnight time value VM, so as to avoid that the light-emitting module 13 is turned on/off at an incorrect time or not due to different day/night time in summer or winter. The correct time automatically adjusts the brightness.

Further, when the above steps are executed to the step of "the brightness sensing control module 11 executes a time setting procedure according to the midnight time VM to generate the first adjustment time H1 and the second adjustment time H2 for the next night (S265)" , as shown in Figure 8, the method further includes the following steps:

The brightness sensing control module 11 provides a first low brightness time T1 and a second low brightness time T2 (S2651);

The brightness sensing control module 11 calculates the first adjustment time H1 of the next night, and the first adjustment time H1 is the subtraction value of the midnight time VM and the first low brightness time T1, that is, the first adjustment time H1= The midnight time VM - the first low brightness time T1 (S2652);

The brightness sensing control module 11 calculates the second adjustment time H2 for the next night, and the second adjustment time H2 is the sum of the midnight time VM and the second low brightness time T2, that is, the first adjustment time H2= The midnight time VM+the second low brightness time T2 (S2653); in this embodiment, the midnight time VM is greater than the first low brightness time T1; the midnight time VM is less than the second low brightness time T2, and the first low brightness time The two low-brightness times T2 are less than the night average TL; the first low-brightness time T1 and the second low-brightness time T2 can be set by the user, or the built-in value of the lamp body 10 can be set by the user After that, there is no need to set it again until the user resets it.

To sum up, in the present invention, the brightness sensing control module 11 drives the power module 12 to control the light-emitting module 13, and automatically adjusts the high brightness/high brightness at the first adjustment time H1 and the second adjustment time H2 at night.
