Abstract

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 delay time of the control chip; can avoid LED lamp flickering, enhance the lighting effects and improve the stability; can prolong the service life of the LED lamps.

Description

technical field [0001] The invention relates to the lighting field, in particular to an LED guardrail tube control circuit. Background technique [0002] The LED guardrail tube is made of high-quality ultra-bright LED (Light-Emitting Diode, light-emitting diode), because of its low power consumption, low heat, long life, impact resistance, high reliability, energy saving and environmental protection, soft light color, high brightness, etc. Features, are widely used in urban landscape lighting. [0003] The existing LED guardrail tube includes at least two LED guardrail lamp control units located in the guardrail tube, each LED guardrail lamp control unit is connected in series, each LED guardrail lamp control unit only controls one LED light-emitting circuit, the entire LED The guardrail tube controls the LED lights in the LED light-emitting circuit connected to each LED guardrail light tube control unit to turn on or go out by transmitting control signals step by step to e...
