Intelligent adapter circuit for LED lamp strip

Abstract

The present invention discloses an intelligent adapter circuit for an LED lamp strip. The intelligent adapter circuit comprises a rectifying circuit, an auxiliary power supply, a light induction circuit, a mains supply sampling circuit, a switching circuit and an intelligent control circuit; the light induction circuit collects light intensity to determine whether the current time is daytime or night, and the mains supply sampling circuit and the intelligent control circuit are matched to control the on and off of the switching circuit, so that the LED lamp strip is automatically controlled to be turned off in the daytime and turned on at night. The conduction time of the switching circuit in each work period can be changed through the remote control of an external terminal device, the time duty ratio of the output voltage of the intelligent adapter circuit in each work period is controlled, and therefore the luminance of the LED lamp strip is controlled. The intelligent adapter circuit has the advantages that the LED lamp strip can be automatically controlled to be turned on at night and to be turned off in the daytime, the luminance of the LED lamp strip can be adjusted under the remote control of the external terminal device when the LED lamp strip is turned on, and the control and operation are both more convenient.

Description

technical field [0001] The invention relates to an intelligent adapter circuit, in particular to an intelligent adapter circuit for LED light strips. Background technique [0002] Existing LED intelligent lighting appliances usually include an intelligent communication module. The intelligent communication module usually has multiple input terminals, multiple output terminals and a wireless signal transceiver terminal. The input terminal of the intelligent communication module is used to access level signals. Each terminal has a fixed voltage threshold. When the voltage of an input terminal rises from less than its voltage threshold to greater than its voltage threshold, the level connected to the input terminal changes from 0 level to 1 level; when the voltage of an input terminal When falling from greater than the voltage threshold to less than the voltage threshold, the level connected to the input terminal changes from 1 level to 0 level. When the voltage of an input ter...

Problems solved by technology

However, when the existing LED light strip adapter is used with the LED light strip, it only has the function of providing a constant working voltage, and the light on or off of the LED light strip needs to be manually operated on site, which is extremely inconvenient to use.
