Problems solved by technology

[0004] The purpose of the present invention is to provide a multimedia touch switch panel. This multimedia touch switch panel solves the situation that the thyristor is subjected to an excessively high reverse electromotive force and is accidentally turned on when the current is switched, and avoids The current will flow through the LED lamps, which solves the phenomenon that the originally controlled LED lamps flicker or cannot be turned off

Abstract

The invention discloses a multimedia touch switch panel, which comprises a current detection circuit, a thyristor, a control module, a zero cross detection circuit and a capacitive touch screen assembly, wherein a central processing module is electrically connected with the control module; an infrared proximity induction module is connected to the central processing module; the current detection circuit and the thyristor are connected between a lamp fire line connection terminal and an electric supply fire line connection terminal in series; a zero line connection terminal and the lamp fire line connection terminal are connected with a thyristor starting current circuit and a dynamic current maintaining circuit in parallel; and a dynamic rectifier-amplifier circuit is arranged between the current detection circuit and the control module, and dynamically adjusts whether the dynamic current maintaining circuit is enabled or not according to a detection current signal from the current detection circuit. According to the multimedia touch switch panel, the condition that the thyristor is unexpectedly conducted due to bearing over-high counter electromotive force in a current switching process is avoided; the condition that current which flows through the control module flows through an LED lamp is avoided; and the phenomenon that the originally controlled LED lamp flickers or cannot be turned off is also avoided.

Description

technical field [0001] The invention relates to the technical field of power switches, in particular to a multimedia touch switch panel. Background technique [0002] LED lamps are widely used because of their advantages such as low power consumption, energy saving, and shock resistance. The control switch of LED lamps has also developed from traditional buttons to touch switches, but the existing LED lamp touch switches can only control the LED lights. Turning on and off only considers lighting, and the brightness of LED lights cannot be adjusted through switches, which cannot meet the needs of more people; for example, the brightness of LED lights cannot be set according to seasons and changes in illuminance. [0003] But the existing touch switch panel, on the one hand, LED lamps can not be well adapted to the traditional thyristor dimmer, because most LED lamps have built-in switching power supply and are driven by this switching power supply, and the switching power sup...
