LED (light emitting diode) guardrail tube control circuit and device

The invention provides an LED guardrail tube control circuit and device. According to the circuit, at least two groups of LED lighting circuits are connected with a control chip; the control chip receives various groups of control signals, which are transmitted by a control signal input end and used for controlling the LED lighting circuits connected with the control chip, and transmits the various groups of control signals to the LED lighting circuits when receiving a trigger signal transmitted by the control signal input end, so that the LED lighting circuit can turn on or off the LED lamps in the LED lighting circuits according to the control signals. The LED guardrail control circuit can control multiple groups of LED lighting circuits simultaneously; under the condition of a constant number of LED lamps, can reduce the number of cascade connection correspondingly and shorten the control signal conveying time correspondingly, namely, control the control signal conveying time to be shorter than the data de
