Embodiment
Below in conjunction with accompanying drawing and embodiment, the technical solution of the utility model is described.
As shown in Figure 1, a kind of Dimmable LED desk lamp described in the utility model, comprises the touch input screen 10, PWM light adjusting controller 20, LED driver 30 and the LED 40 that are electrically connected successively.Dimmable LED desk lamp of the present utility model, PWM brightness adjustment control is adopted to carry out brightness adjustment control to the LED of desk lamp, adopt touch input screen 10 as control inputs device simultaneously, PWM light adjusting controller 20 controls the process of the brightness change of LED 40, the brightness of LED 40 is determined by the duty ratio of pwm signal, its scope be %0 to 100%, corresponding curent change scope also can from %0 to 100% change.So LED desk lamp can realize the dimming scope of ultra-wide, and do not change the colourity of LED 40.The utility model can realize intellectualized operation, and fashion is convenient, simple to operate, by operating multifunction touch screen control panel, can regulate brightness and colour temperature, make it reach the lighting effects oneself wanted.
For touch input screen 10, as depicted in figs. 1 and 2, comprise starting switch 11, reset switch 12, colour temperature adjuster and brightness regulator 15 particularly, described colour temperature adjuster comprises colour temperature by-pass cock 13 and colour temperature adjustable ring 14 further, delayer 16 and/or counter 17 can also be comprised, all be connected on touch controller 18, identify various operation by touch controller 18.In concrete use procedure, first LED desk lamp after being powered up, by pressing the starting switch 11 of touch input screen 10, opens light source, but before not opening starting switch 11, other button of touch input screen 10 touches void in whole, to avoid misoperation; Then user can select brightness regulation or colour temperature to regulate, if select brightness to carry out light modulation, will brighten gradually first by brightness regulator 15LED lamp 40, if again by brightness regulator 15 after loosing one's grip, will perform contrary operation.By counter 17, the number of operations pressing brightness regulator 15 is counted, press particularly when number of times is odd-times and increase brightness, press when number of times is even-times and reduce brightness.If select colour temperature to regulate, then need first by colour temperature by-pass cock 13, colour temperature adjustable ring 14 is just activated, now turn-take in the region of colour temperature adjustable ring 14 by finger and realize regulating the object of colour temperature, turn-take and rotated and reverse, its colour temperature regulating effect is contrary, takes two turns, reaches adjustment peak value.If press reset switch 12, then automatically brightness and colour temperature can be returned to system default value, such as brightness 50%.When pressing in starting switch 11, reset switch 12 or colour temperature by-pass cock 13 any one, needing time delay could identifying operation instruction, carries out delays time to control, avoid misoperation by delayer 16 to these operations.
In addition, also comprise the memory 21 be connected with PWM light adjusting controller 20, after namely each end of operation is pointed and is left touch input screen 10, the brightness that user arranges by capital and color temperature parameters are stored in memory 21, then open LED 40 with the brightness of automatic calling and obtaining user last time setting and colour temperature when next time turns on light, be convenient for people to use.
For PWM light adjusting controller 20, adopt STC single-chip microcomputer particularly, first STC single-chip microcomputer sets up I2C communication mechanism with touch input screen 10, STC single-chip microcomputer is by sending the relevant configuration of a series of instructions initialize touch input screen 10, complete the initial communication with touch input screen 10, then user operation touch-screen is waited for, after user completes a touch operation, STC single-chip microcomputer is processed to corresponding signal by I2C communications reception, finally change into pwm signal and output to LED driver 30, and then control brightness or the colour temperature of LED 40.
For LED driver 30, adopt PT4115 constant-flow driver particularly, the signal of the PWM inputted by PWM light adjusting controller 20, PTT4115 constant-flow driver can be translated into corresponding electric current, thus change power output, regulate brightness and the colour temperature of LED 40.The brightness of LED 40 is determined by the duty ratio of pwm signal, its scope be %0 to 100%, corresponding curent change scope also can from %0 to 100% change.So LED desk lamp can realize the dimming scope of ultra-wide, and do not change the colourity of LED 40.
