Product Details

 

Features
Touch dimmer module can be achieved led Light touch switch control and dimming. It has the following features and benefits:

 The light intensity can be adjusted according to need, a wide range of options, easy operation.

 You may have medium ?Such as glass, acrylic, plastic, ceramics, etc.?Touch function to achieve isolation tection, safe.

 The applied voltage range, can 2.4 ~ 4.5V Between any choice.

 Application circuit is simple, few peripheral devices, easy cessing and low cost.

 Power interference and anti-interference characteristics of a good phone. EFT can reach 2KV Above; close, multi-angle cell phone interference case,

Touch response sensitivity and reliability is not affected.

6. installation: Without direct contact with the copper foil, may be separated by more than 3mm acrylic glass or plastic dimming.

7. use: LED module can be controlled, with lights and other ducts. Suitable for indoor lamps, LED lighting dimmer, DIY lamp dimmer retrofit the best accessories.

8. Function: singlet touch using capacitive touch principle, namely the induction sensitive fingertips. The default is having a switching function, dimming function with brightness memory slowly fades the LED touch stepless dimming function. When the lights brighten slowly, slowly dimmed lights, effectively prevent eye irritation.

9. Dimming mode: PWM stepless dimming

10. Wiring: PCB board (VCC, GND) power input, (LED +, LED-) is connected to the positive and negative grade LED lights (fingerprint) as a ground touch area can also lead wiring?Note that the wiring is not too long, after qualifying Available with a small copper do the induction area?, Copper area recommendations about 2x3cm. The board comes with copper foil module attached to the side of the shell side.

11. Instructions

a) Click Touch?Touch duration of less than 550ms?When the bright lights off control can be achieved. One-click touch lights; once again tap the touch, lights out. Light illuminated initial brightness fixed at 90 percent of full brightness.

b) Touch Press?Touch duration greater than 550ms?When, enabling light without brightness adjustment. A long press touch, gradually increasing light levels, light levels when released after releasing the stop time corresponding to the brightness, if press for more than 3 seconds, the light intensity does not change the maximum brightness; press again touch, decreased light levels, light levels when released parked in the release time corresponding brightness, long time if more than 3 seconds, the light intensity reaches a minimum brightness after no change
Of. So the cycle.

12. Debugging Tips

If the error occurs when commissioning trigger or not trigger, the following possible reasons:

a ?Touch the line too thick

b ?Touch the line is too long

c ?Copper is not big enough

d ?Close to the switching power supply terminal interference

e ?Touch unreasonable parameters C1

 

 

 

Features:

 TI Touch the corresponding input led Lighting control output. There are four optional features by T1 and T2 The input pin before

State to decide. details as follows:

 T1 = 1 , T2 = 1 Correspondence: Without memory brightness jection truding out of the dark led Touch stepless dimming function

 T1 = 0 , T2 = 1 Correspondence: Without memory slowly fades in brightness led Touch stepless dimming function

 T1 = 1 , T2 = 0 Correspondence: with brightness of memory slowly fades led Touch stepless dimming function

 T1 = 0 , T2 = 0 correspond: led Three sections touch dimmer function

 

 Without memory brightness jection truding out of the dark led Touch stepless dimming functions are as follows:

 At initial power-up, the lamp is off OFF state.

 Click Touch?Touch duration less than 550ms ?When the bright lights off control can be achieved. One-click touch lights; once again tap the touch, lights out. So the cycle. Lights on or off when off, no brightness buffer. Lighting and lighting of the initial luminance is fixed at full brightness 50% .

 Touch Press?Touch duration greater than 550ms ?When, enabling light without brightness adjustment. A long press touch, gradually increasing light levels, light levels when released parked in the release time corresponding brightness, if a long time over 3 Seconds, the light brightness reaches the maximum brightness does not change; press again touch, light levels decreased gradually, releasing the light levels stopped at the release time corresponding brightness, if a long time over 3 After seconds, the light intensity reaches a minimum brightness does not change. So the cycle.

 Click on touch Touch and press are to use at any time, without interference with each other and function restrictions.

 Without memory slowly fades in brightness led Touch stepless dimming in brightness without jecting out sudden dark memories led Touch base stepless dimming function on, click on the touch turn on and off when the lights slowly by making a smooth transition from low brightness to the initial brightness of the lights, turn off the lights when you click the touch, so the brightness of the light by the current slow reduce until smooth shut off, so as to achieve the brightness slowly changing visual cushioning effect, tect the eyes and vision effect.

With the brightness of the memory slowly fades led Touch stepless dimming in brightness without the memory slowly fades led Increase the brightness memory function touch stepless dimming function basis. I.e. Uninterruptible power supply case, the brightness per-click touch when the lights will be remembered, the next click will turn on the lights when touched as this brightness initial brightness. in Under power failure situation, first click on the touch lights power on again after the initial brightness is fixed at full brightness 50% .

 led Three sections touch dimmer function

? At initial power-up, the lamp is off OFF state.

? CPC touch, light brightness Press Low brightness Brightness high brightness Destroy Followed by cycling.

Sensitivity adjustment

Note: Constant dimmer output connector led , You must limit resistor string!

Limiting resistor calculation: R = ? Vi - Vled ? / Io

among them, Vi Input voltage , Vled All led The total pressure drop of the lamp, Io Total current light strings. Should be considered when calculating Vi , Vled Floating range. Usually when the battery is fully charged Vi It will be too large. led After the heat up, Vled It will drop! Prevent excessive current damaging the module or lamp beads.
