Description
Technical field
The invention belongs to dimming technique field, and in particular to a kind of LED lamplight touch dimmer.
Background technology
The purpose of light modulator is to adjust the different brightness of light.Promote mean power by decreasing or increasing RMS-voltage
The light output of varying strength caused by light.Although variable voltage equipment can be used for various purposes, this regulation and control are intended to control
System illumination.Modern light modulator is established by silicon controlled rectifier (SCR), rather than potentiometer or variable resistor because light modulator have it is higher
Efficiency.Current dimmer for light control pattern is more traditional, does not possess the function of touch sensible light modulation.A kind of LED is proposed for this
Light touch dimmer.
The content of the invention
It is an object of the invention to provide a kind of LED lamplight touch dimmer, to solve what is proposed in above-mentioned background technology
Problem.
To achieve the above object, the present invention provides following technical scheme：A kind of LED lamplight touch dimmer, including three poles
Pipe Q1, Q2, FET, R3, C2, voltage-stabiliser tube, R7, C1, R1, R2, R3, R4, R5, R6.The triode, FET with
Single-chip microcomputer forms touch signal amplification and control circuit, and the R2, R3, C2, voltage-stabiliser tube are single-chip microcomputer power supply circuit, and the R6 is
Link touch point and Q2 insulation blocking resistance, Q1 conducting is controlled by single-chip microcomputer through R1.
Further, one end of the R6 is provided with touch point.
Further, one end of the R2 is connected with single-chip microcomputer, and R1 both ends respectively connect with single-chip microcomputer and output power end
Connect.
The technique effect and advantage of the present invention：The LED lamplight touch dimmer, human hand sensing touch light modulation, pass through three poles
Human-induced signal's amplification and control single chip computer regulation output ON time, single-chip microcomputer are controlled to adjust LED by pipe and FET
Working condition and reach sensing light modulation purpose.
