[0010] As a preferred technical solution, the control signal of the central control system is transmitted using a serial communication protocol, and the control signal is in a 16-bit binary format, including:

[0057] Central control system: The central control system is a system that sends control signals and can be made of sub-modules made of embedded chips. The central control system pre-sets the content of the control signal according to the number of track lights.

[0058] Sub-orbital lamp: The lamp body of the track lamp, usually composed of halogen lamps. Each section of the sub-orbital lamp is about 0.3 meters to 1 meter in length. Each section of the sub-orbital lamp is equipped with a track lamp power supply to supply power to the halogen lamp and the single-lamp control system. Each sub-orbital lamp is connected end to end through 2 power lines and 2 signal lines. The halogen lamp is powered by 2 power lines. One section of the track lamp composed of sub-orbital lamps is connected to the central control system, and the connection method is 2 power lines and 2 signal lines.

[0059] Single-lamp control system: A whole section of track lamp is composed of multiple sections of sub-orbital lamps, and a single-lamp control system is installed on each section of the sub-orbital lamp. The function of the single-lamp control system is to control the current source current of a single section of the sub-orbital lamp, thereby controlling the brightness of a single section of the track lamp.

The signal is transmitted through the signal line, and the transmission method is to send the control signal content in a fixed format through a fixed communication protocol. The communication protocol can adopt the basic serial communication protocol. The control signal content is a 16-bit binary signal, and the format is: four signal segments of sub-lamp number, on / off state, light mode, and brightness. Each signal segment takes 6 bits, 1 bit, 1 bit, and 8 bits respectively.

[0065] S2: The single-lamp control system preprocesses the received communication signal. After the single-lamp control system receives the control signal issued by the central control system, the single-lamp control system controls according to the control signal. If the sub-orbital lamp corresponding to the single-lamp control system is the sub-lamp number of the control signal, then if the on / off state of the control signal is off, that is, the signal is 0, the constant current source is turned off; if the on / off state of the control signal is on, that is, the signal is 1, the constant current source is turned on, and the output current size of the constant current source is divided into 256 gears, each gear corresponding to the brightness of the halogen light source, with gear 0 being the darkest and gear 255 being the brightest.

Memory B stores the brightness signal value C n (n is the sub-orbital lamp number, taking 1, 2,...). Memory C stores the modulation value H n (n is the sub-orbital lamp number, taking 1, 2,...).

[0068] S3.1: The single lamp control system detects the lighting mode. When the lighting mode is 0, it enters the dimming mode.

Then the calculation method for obtaining the improvement amount H n is as follows:

[0070]

[0071] Then Ln at the current time = Ln + Hn;

[0072] S3.2: The single lamp control system detects the lighting mode. When the lighting mode is 1, it enters the lighting mode.

[0073] The single lamp control system obtains the Cn + k value (k = -p, -p + 1,..., p - 1, p, p can be taken as 20 for example, and adjusted according to the number of sub-orbital lamps) of the adjacent sub-orbital lamps.

[0074] The calculation method for obtaining the improvement amount Hn is as follows:

[0075] Take the average illumination ave:

[0076]

[0077] The adjustment coefficient G is:

[0078]

[0079] Let t be the adjustment speed coefficient, which can be taken as 10. Let s be the adjustment speed coefficient, which can be taken as 3;

[0080] The brightness Ln of the sub-orbital lamp is:

[0081]

[0082] S4: The sub-lamp power supply system performs brightness dimming according to the Ln value of the single-lamp control system;

[0083] In summary, the present invention has the following advantages compared with the prior art:

[0084] (1) It is easy to design and build. Specifically, the method for designing and installing facilities is simple. All electronic components and control methods are existing mature technologies, which can be flexibly arranged and designed according to actual needs.
