Section switch for modulating LED operation through touch control and pulse output

Abstract

The invention discloses a section switch for modulating LED operation through touch control and pulse output. The section switch comprises a touch key module for collecting a touch signal, a master control module electrically connected with the touch key module so as to modulate a control signal according to the touch signal, and a pulse output module; the control end of the pulse output module iselectrically connected with the master control module so as to receive a control signal; the input end of the pulse output module is electrically connected with the external AC and the pulse output module outputs a pulse signal according to the control signal; the output end of the pulse output module can be electrically connected with an external LED driving lamp bank for regulating color temperature or brightness, thereby switching the light-emitting condition of the LED driving lamp bank for regulating color temperature or brightness. The design is free from repeatedly turning on and of the lamps, the flashing frequency is reduced; and meanwhile, the master control module can regulate the pulse signal according to the switch-on state of the existing LED driving lamp bank and the switch-on logic relation of the on and off of the first output end and the second output end.

Description

technical field [0001] The invention relates to the lighting field, in particular to a section switch for modulating LED operation. Background technique [0002] There are many kinds of LED lamps on the market that can adjust the color temperature or brightness. The more common one is a color temperature or brightness adjustable LED drive lamp group, which includes the first lamp, the second lamp and the switch switching drive with different color temperatures. chip, the switch switching drive chip includes an input terminal, a first output terminal electrically connected to the first lamp, and a second output terminal electrically connected to the second lamp, and the input terminal of the switch switching drive chip is connected to a conventional switch key component The switch switching driver chip can control the on and off of the first output terminal and the second output terminal according to the switch switching signal input from the input terminal (within a certain ...

[0002] There are many kinds of LED lamps on the market that can adjust the color temperature or brightness. The more common one is a color temperature or brightness adjustable LED drive lamp group, which includes the first lamp, the second lamp and the switch switching drive with different color temperatures. chip, the switch switching drive chip includes an input terminal, a first output terminal electrically connected to the first lamp, and a second output terminal electrically connected to the second lamp, and the input terminal of the switch switching drive chip is connected to a conventional switch key component The switch switching driver chip can control the on and off of the first output terminal and the second output terminal according to the switch switching signal input from the input terminal (within a certain time interval). When the user turns on or off the lamp through the switch button part The corresponding switch switch signal can be generated, and the switch switch signal can be generated by continuously pressing the switch key part in a short time, and then switch the first light on or the second light on or the first light and the second light on mixedly, However, in practical applications, if the lamps are turned on and off many times, a strong light-dark contrast will be generated instantly when the lights are switched on and off, which will dazzle the human eyes.
