Intelligent LED lamp strip lighting circuit without stroboscopic dimming

Abstract

The invention discloses an intelligent LED lamp strip lighting circuit without stroboscopic dimming. The circuit comprises a rectifying circuit, a voltage conversion circuit, an auxiliary power supply, an intelligent module circuit, a PVC (polyvinyl chloride) conversion circuit, a level conversion circuit, a complementary switch circuit and an LED lamp strip, the intelligent module circuit communicates with an external terminal device, the intelligent module circuit receives a light-off control signal, a light-on control signal or a dimming control signal sent by the external terminal device, and the level conversion circuit generates a corresponding electric signal to control the working state of the voltage conversion circuit under the control of the intelligent module circuit, so that the LED lamp strip emits light or does not emit light. When the LED lamp strip emits light, the intelligent module circuit outputs a corresponding dimming signal based on the dimming control signal to control the luminous intensity and the luminous color temperature of the LED lamp strip; and the circuit has the advantages that: intelligent stroboflash-free dimming can be realized through the intelligent module circuit, and the current intelligent lighting requirement is met.

Description

technical field [0001] The invention relates to an intelligent LED strip lighting circuit, in particular to an intelligent LED strip lighting circuit without stroboscopic dimming. Background technique [0002] In the intelligent control equipment, there is usually an intelligent module circuit. The intelligent module circuit can communicate with the external terminal equipment wirelessly, and set the working state of the intelligent control equipment by receiving the control signal sent by the external terminal equipment. In addition to the wireless communication port for communicating with external terminal equipment, the intelligent module circuit also has a number of input / output ports, and these input / output ports can be set to different functions. The signals input / output by the input / output ports of existing intelligent module circuits are usually digital electrical signals. In lighting industry applications, smart module circuits usually output PWM signals to adjust ...
