It should be noted that, without conflict, the embodiments of the present utility model and features in the embodiments may be combined with each other.

It is to be understood that this description is merely exemplary in nature and is not intended to limit the scope of the present utility model.

Referring to fig. 1 and 2, a circuit structure of a shunt control curtain lamp comprises a controller, wherein the controller is connected with a plurality of lamp strings, the lamp strings are composed of at least one magical color LED, and a signal converter is connected between the lamp strings and the controller, and the circuit comprises the following working steps:

s3, driving an LED, wherein the multicolor LED receives the signal SIN, and the multicolor LED is lightened; according to the utility model, the signal converter is added before each light string, the signal converter acquires the signal SIN, and the signal SIN is judged and conducted according to the signal SIN required by each light string, so that the problem that the signals among the light strings are not influenced by each other is solved, the work of the following light strings is not influenced even if one multicolor LED in the light string is damaged, the conducted wires are fewer, and the cost is reduced.

The model of the multicolor LED is SK6812RARE, the multicolor LED is provided with 6 pins, and the multicolor LED forms a connection mode of a light string: the input end of the first multicolor LED receives a signal SIN, the output end of the first multicolor LED is connected with the input end of the second multicolor LED, the signal SIN is equivalent to the series connection between the multicolor LEDs in the light string, the signal SIN can penetrate through the whole light string, the signal SIN is consistent, and the lighting effect is consistent.

Working principle: each fantasy LED has a number, each signal converter is firstly encoded, the encoded signal converter forwards required data to the drooping fantasy LEDs through counting identification, for example, a first string of lights has 5 fantasy LEDs with numbers 1-5, a second string of lights has 10 fantasy LEDs with numbers 6-15, and the like, when the signal converter receives a signal SIN, and the fantasy LEDs with numbers 1-5 are identified to be lighted, the first signal converter is conducted, if the signal SIN is 6-15, the string of lights connected with the first signal converter is not conducted, and the string of lights connected with the second signal converter is conducted; thus realizing the effect of series connection to parallel connection.
