Control signal transmission method for lamp system

A control signal transmission method for a lamp system, comprising the following steps:

• periodically acquiring signal states of a red-line original control signal, a green-line original control signal and a blue-line original control signal;
• outputting a red-line conversion signal, a green-line conversion signal, and a blue-line conversion signal sequentially in a single output period according to the signal states of the red-line original control signal, the green-line original control signal and the blue-line original control signal;
• performing voltage stabilization on the red-line conversion signal, a green-line conversion signal, and a blue-line conversion signal which are output sequentially to obtain a red-line regulation signal, a green-line regulation signal and a blue-line regulation signal with different levels from each other;
• outputting a combined control signal containing information of the red-line regulation signal, the green-line regulation signal and the blue-line regulation signal;
• receiving and detecting the combined control signal to obtain the red-line regulation signal, the green-line regulation signal and the blue-line regulation signal which are in different voltage levels;
• and
• outputting the red-line regulation signal, the green-line regulation signal and the blue-line regulation signal with different voltage levels to lamps of the lamp system;
• wherein the signal state is a high level or a low level;
• or the signal state is presence of a signal or absence of a signal;
• wherein the signal states of the red-line original control signal, the green-line original control signal and the blue-line original control signal are acquired according to an acquisition period, and the output period is equal to the acquisition period;
• wherein in a case where the signal states of two original control signals of the red-line original control signal, the green-line original control signal and the blue-line original control signal are the high level/the presence of said signal, the combined control signal is consisted of two regulation signals corresponding to the two original control signals, wherein duty cycles of the two regulation signals in the combined control signal are respectively ½.
