The operation of coloured light study lamp described in the utility model is described below：

When any membrane keyboard in a touching membrane keyboard D1, membrane keyboard D2, membrane keyboard D3, control program effect is being edited and recorded in advance Under, desk lamp realizes different function：Membrane keyboard D1 is timing and bright-dark function；Membrane keyboard D2 is to adjust different brightness functions； Membrane keyboard D3 is that three kinds of coloured light of red, green, blue exchange function automatically.

1, the timing function of membrane keyboard D1 is that children's setting timing when study is using desk lamp is rested under mode of learning.It touches The bright-dark function of key D1 be in child desk lamp light gradually blast and it is less dazzling, to protect eyes, close platform At the end of lamp or timing, light gradually it is dimmed to extinguish and guarantee it is less dazzling, to protect eyes.Specifically：When a touching touching When touching key D1, point touching signal touches the PWM-W output pin that shares of chip IC 1 by programmable capacitor formula, output duty cycle by 0%-100% classification gradually increases so that continuing for some time the pwm signal of T, and output signal passes through constant-current driving LED chip Illumination LED lamp bead negative pole end is connected in the DIM foot of IC2, realizes desk lamp often by secretly gradually illumination highlights；Continuing for some time T is Timing function, at the end of the output pwm signal time T of setting, programmable capacitor formula touches chip IC 1 and exports PWM-W signal just It is gradually decreased by 100%-0%, the DIM foot pwm signal in constant-current driving LED chip IC 2 is caused gradually to be subtracted by 100%-0% Few input, headlamp often highlight gradually low-light level gradual change, electrically disconnect until leading to illumination LED lamp bead negative pole end, desk lamp illumination Breath goes out.

2, membrane keyboard D2 has the different brightness functions of adjustment：When (such as resting or playing) not in mode of learning, need not Membrane keyboard D2 can be used in same brightness；When starting, desk lamp brightness is darker, and every touching is primary to touch strong D2, and lamplight brightness increases by 1 Times, point touching 4 times are that can reach maximum brightness；When closing desk lamp, long touch membrane keyboard D2, then lamplight brightness is gradually reduced to and puts out It goes out.Specifically, point touching signal touches chip IC 1 by programmable capacitor formula and shares when touching membrane keyboard D2 n-th Illuminating LED lamp is connected by the DIM foot of constant-current driving LED chip IC 3 in PWM-W output pin, the pwm signal for exporting duty ratio corresponding Pearl negative pole end realizes that desk lamp corresponds to different brightness of illumination；Programmable capacitor formula touch chip IC 1 can edit and record in advance 0-N times it is right Answer output duty cycle 0-100%PWM difference section pwm signal, when touching membrane keyboard D2 n-th when, 1 output duty cycle of chip IC 0-100%PWM signal, the DIM foot in constant-current driving LED chip IC 3 receive input pwm signal, and illumination LED lamp bead is connected Negative pole end, when duty ratio is 0% without pwm signal input, then towards illumination LED lamp bead negative pole end in constant-current driving LED chip IC 3 Circuit disconnects, and desk lamp illumination is closed；

As touching touch key D1 or touch key D2 key, programmable capacitor formula touches the closing of 1 program instruction of chip IC and leads to Coloured light switching circuitry output IO exports PWM, guarantees that dimmer switch circuit or light switch circuit work independently.

3, dimmer switch circuit D3 is strong has three kinds of coloured light of red, green, blue and exchanges function automatically, cooperates the children of amblyopia to do and changes It is apt to restitution.When every click-point is touched membrane keyboard D3 mono- time, red light, green light, blue light conversion；As double-click membrane keyboard D3 When, the three coloured light LED lamp bead being hidden in the inner cover of lampshade bottom, successively by red light, green light, blue light automatic conversion；Work as length When membrane keyboard D3, colored lights are dimmed to light-off；

When dimming function or illumination functions still at work, click membrane keyboard D3, programmable capacitor formula touches 1 journey of chip IC Sequence instruction, which is closed, leads to dimmer switch circuit or light switch circuit output end 1O output PWM, and dimming function is closed or illumination function It closes.

When often clicking one time when membrane keyboard D3, end is touched by programmable capacitor formula and touches chip IC 1DE output pin RPWM Or the base stage of R triode or G triode or B triode that BPWM or GPWM and triggering are correspondingly connected with, realize R triode, tri- pole G Pipe, B triode, to realize that corresponding red, green, blue three coloured light LED lamp bead shines.As long membrane keyboard D3, touch end passes through can Programming 1 output pin RPWM or BPWM or GPWM output signal PWM duty cycle of capacitance touch chip IC is changed by 100%-0%, Corresponding R triode, G triode, B triode signal code are gradually reduced to closing, and colored lights are dimmed to light-off.

The basic principles and main features and technological merit of the utility model have been shown and described above.Those skilled in the art Member it should be appreciated that described in above-described embodiment only illustrate the principles of the present invention, do not departing from the spirit of the present invention Under the premise of range, the utility model also has various changes and improvements, these changes and improvements both fall within claimed In the scope of the utility model.The utility model requires protection scope is by claims and its equivalent thereof.
