S2, operation steps: acquiring real-time brightness L of a place in a target space area detected by a light sensor of a currently-started lamp n The method comprises the steps of carrying out a first treatment on the surface of the The external space brightness obtained by adopting the light sensor is L t 。
The step realizes automatic adjustment of illumination brightness by installing a light sensor and a controller system in a room. The light sensors continuously detect real-time brightness in the target space region and transmit the data to the controller, and the other group of light sensors are used for detecting external space brightness of the external space and transmitting the data to the controller. The controller automatically adjusts the brightness of the lamp according to the data collected by the sensor so as to keep the proper illumination in the room.
As shown in fig. 3, the S3 operation steps are: comparing the real-time brightness L of the places n Relation to controlling brightness L
S301: the controller compares the real-time brightness L in the target space region n And a set control luminance L.
S302: judging according to the comparison result:
if L n And (L) indicating that the brightness of the current place meets the set requirement, returning to S2, and continuing to monitor the real-time brightness and adjusting the brightness of the lamp.

By gradually closing the lamp, the brightness of the lamp can be stably adjusted, and the discomfort of a user caused by abrupt brightness change is avoided. Meanwhile, the uniformity of brightness can be effectively ensured.
For example, the actual brightness in an office is 2000 lumens and the control brightness is set to 1500 lumens. From S401, Δl=2000-1500=500 lumens is calculated. Then, according to S402, the number of lamps to be turned off k=Δl/ln=500/2000=0.25 is calculated. Assuming 10 lamps in the office, 2-3 of the lamps can be turned off at intervals according to S403 to gradually decrease the indoor brightness until the set control brightness of 1500 lumens is reached. Therefore, the illumination can be intelligently adjusted according to the actual brightness, the comfort level is improved, and the energy is saved.
As shown in fig. 5, step S5 is: gradually starting the unopened lamp, adjusting the brightness of the lamp according to the brightness adjusting program of the controller until the control brightness L is reached, and returning to S2.
The specific operation steps are as follows:
s501: calculating the difference DeltaL=L-L between the control brightness and the current place brightness n . This step is to determine the gap between the current actual brightness and the set brightness for subsequent stepwise adjustment of the lamp brightness.
S502: determining the number K of lamps needing to be turned on, wherein K=delta L/L n . According to the difference between the actual brightness and the set brightness, the number of lamps which need to be turned on gradually is calculated so as to increase the indoor brightness gradually.
S503: and starting K lamps which are not started at present and are M lamps at intervals so as to gradually increase the indoor brightness until the set control brightness L is reached. The step is to gradually increase the brightness of the lamps according to the calculated number of the lamps to be turned on so as to realize the adjustment of the control brightness. The interval opening can ensure the uniformity of brightness.
According to the step, the lamps are gradually started according to the difference between the actual brightness and the set brightness, so that energy sources can be effectively saved, and excessive illumination is avoided. By gradually starting the lamp, the brightness of the lamp can be stably regulated, and the discomfort caused by abrupt brightness change to a user is avoided. Meanwhile, the uniformity of brightness can be effectively ensured.
For example, the actual brightness in one conference room is 1000 lumens, and the control brightness is set to 1500 lumens. From S501, Δl=1500-1000=500 lumens is calculated. Then, according to S502, the number of lamps to be turned on k=Δl/ln=500/1000=0.5 is calculated. Assuming 8 lamps in the conference room, 4 lamps therein may be turned on at intervals according to S503 to gradually increase the indoor brightness until reaching the set control brightness of 1500 lumens. Therefore, the illumination can be intelligently adjusted according to the actual brightness, the comfort level is improved, and the energy is saved.

wherein L is n =l, indicating that the current location brightness meets the set requirement, returning to S2;
wherein L is n More than L, the brightness of the current place is higher than the set requirement, and the operation is carried out according to S4;
wherein L is n < L, which means that the brightness of the current place is lower than the set requirement, and executing according to S5;
s4a: gradually reducing the power of the turned-on lamp, and adjusting the brightness of the lamp according to the brightness adjusting program of the controller until the control brightness L is reached, and returning to S2; the step gradually reduces the dimming method of the power of the started lamp, and gradually adjusts the brightness of the lamp through the brightness adjusting program of the controller until the set control brightness L is reached. The method can realize stable adjustment of the brightness of the lamp and avoid abrupt brightness change.
As shown in fig. 7, the specific steps are as follows:

Therefore, the illumination can be intelligently adjusted according to the actual brightness, the comfort level is improved, and the energy is saved.
For example: the actual brightness in one location was 2000 lumens and the control brightness was set to 1500 lumens. From S4a01, Δl=2000-1500=500 lumens is calculated. Then, according to S4a02, the number of lamps k=Δl/Δlmax required to reduce the luminance is calculated. Let Δlmax be 100 lumens, then k=500/100=5. Then according to S4a03, the brightness of the 5 lamps with the highest brightness is gradually reduced until the real-time brightness approaches to the control brightness. Therefore, the illumination can be intelligently adjusted according to the actual brightness, the comfort level is improved, and the energy is saved.
