The light source control system 100 includes: the main control device 110, at least one brightness adjustment module 120 and at least one light source 130. Wherein, the master control apparatus 110 includes: a main control module 113, a brightness sensor 112 and an intelligent switch 111. The main control module 113 is respectively connected with the brightness sensor 112 and the intelligent switch 111, the main control module 113 is connected with the at least one brightness adjustment module 120 through an RS485 bus, and each brightness adjustment module 120 in the at least one brightness adjustment module 120 is connected with the at least one light source 130.
The input end of the intelligent switch 111 is further used for being connected with a commercial power (AC 220V), and the output end of the intelligent switch 111 is connected with the at least one brightness adjusting module 120. The intelligent switch 111 is in an on or off state according to a control instruction sent by the main control module 113, and when the intelligent switch 111 is in an on state, at least one brightness adjusting module 120 and at least one light source 130 can be powered, so that the control of the light source 130 can be realized by controlling the on or off of the intelligent switch 111. In the most alternative, the intelligent switch 111 may be a relay, where a common terminal of the relay is used to connect to a mains supply, a normally open contact of the relay is grounded, a normally closed contact (i.e., an output terminal) of the relay is connected to at least one brightness adjustment module 120, a control terminal (coil) of the relay is connected to the main control module 113, the relay is in an off state when the common terminal is connected to the normally open contact, and the relay is in an on state when the common terminal is connected to the normally closed contact. Wherein, the relay can be selected from the devices commonly used in the market at present.
The control command may be a level signal, such as a high level or a low level. The low level indicates a voltage having a voltage value lower than a first value, which is a common value in the industry. For example, the first value is typically 0.0V-0.4V for TTL circuits and 0.0-0.1V for CMOS circuits. In the embodiment of the present invention, preferably, the first value is 0V, i.e., the low level is 0V. The high level indicates a voltage having a voltage value higher than a second value, which is a common value in the industry. For example, the second value is typically 2.4V-5.0V for TTL circuits and 4.99-5.0V for CMOS circuits. In the embodiment of the present invention, preferably, the second value is 3.3V, that is, the high level is 3.3V.
The brightness sensor 112 is configured to collect brightness signals of the surrounding environment, and send the collected brightness signals to the main control module 113. The luminance sensor 112, which may also be referred to as a light sensor, is a sensor that senses light luminance and converts it into a usable output signal, and may be a sensor of the PIC series, such as a PIC-1521BBRIGHT or B series, such as a BPV34CBRIGHT.

For example, when the brightness signal is lower than a first preset threshold, such as in the evening or in the cloudy day, and the brightness is insufficient, the main control module 113 controls the intelligent switch 111 to be in a conductive state, and then the light source 130 can be turned on; for another example, when the brightness signal is higher than a second preset threshold value greater than the first preset threshold value, and the brightness is sufficient, the main control module 113 controls the intelligent switch 111 to be in an off state, and then the light source 130 can be turned off. In addition, because the brightness of the light sources 130 required for different illumination is different, for example, when the day starts to turn black, the required illumination intensity is different from the illumination intensity after the day is black, so the main control module 113 can also send an RS485 signal to control the current output by the at least one brightness adjusting module 120, so as to adjust the brightness of the at least one light source 130, and realize the process of gradually brightening the light or gradually dimming the light from brightening.
