Abstract

The invention provide a light emitting diode (LED) control structure, which comprises a touch sensing circuit and a control module, wherein the touch sensing circuit comprises a metal touch sheet for sensing touch, and a sampling resistor and a divider resistor which are serially connected with the metal touch sheet in turn; the control module is provided with a plurality of input / output ends and is used for connecting the touch sensing circuit for detecting the touch, generating a control signal according to the touch, and outputting the control signal; and each of the input / output ends comprises a charging-discharging control end for serially connecting the touch sensing circuit, a sampling end for connecting the public ends of the sampling resistor and the divider resistor, and a control end for outputting the control signal. Besides, the invention provides an LED control method. According to the LED control structure and the LED control method, the touch sensing circuit is used for sensing the touch of hands, the control signal is generated according to the touch condition for controlling an LED, and the metal touch sheet of the touch sensing circuit is used for sensing the touch, thus the problem related to the service life of a mechanical switch is solved. Besides, the whole touch sensing circuit has a simple structure.

Description

【Technical field】 [0001] The present invention relates to LEDs, in particular to an LED control structure, and also to an LED control method. 【Background technique】 [0002] With the development of LED technology, the application of LED in the field of general lighting is more and more extensive. When LED is used as the light source of lighting appliances, since the LED needs a constant current when it works, it needs a special driving power supply, and the driving power needs a switch to control the lighting of the lamp. The traditional switch control method in the circuit is mainly a mechanical switch. The input mechanical switch that controls the drive power supply by turning on or off the energized line has a short lifespan, and is not suitable for occasions that require a long lifespan, especially in the control of corridor lights. occasion. 【Content of invention】 [0003] In view of this, it is necessary to provide an LED control structure with long life and conven...
