Features
The touch dimming module can realize the touch switch control and brightness adjustment of the LED light. It has the following features and advantages:
1. The brightness of the light can be adjusted as needed. The selection range is wide and the operation is simple and convenient.
2. It can realize touch function under the condition of isolation protection of medium (such as glass, acrylic, plastic, ceramics, etc.), and it has high safety.
3. The application voltage range is wide and can be arbitrarily selected between 2.4~4.5V.
4. The application circuit is simple, the peripheral components are few, the processing is convenient, and the cost is low.
5. Anti-power interference and mobile phone interference characteristics are good. EFT can reach ±2KV or more; close range. Multi-angle mobile phone interference,
Touch response sensitivity and reliability are not affected.
6. Installation: no need to directly contact the copper foil, you can dim through the acrylic glass or plastic more than 3mm.
7. Use: Can control LED module. Light strip and other products. Suitable for indoor table lamp, LED lighting dimming, DIY lamp dimming conversion best accessories.
8. Function: Single-line touch, using the principle of capacitive touch, the sensitive touch tentacles can be reached. The default is to have the switch function. Dimming function. With the brightness memory gradually clear and dark LED touch stepless dimming function. Slowly change when turning on the light Bright, slowly dim when turning off the light, effectively avoiding eye irritation.
9. Dimming mode: stepless PWM dimming
10. Wiring method: PCB board (VCC, GND) is the power input, (LED+, LED-) is connected to the LED lamp positive and negative (fingerprint) for the touch area, but also for wiring (note that the wiring is not too long, the outlet After the introduction, use a small piece of copper to make the sensing area), the copper area is recommended to be about 2x3cm. The copper foil module on the board is attached to the side of the shell.
11. How to use
a) When the touch is touched (touch duration is less than 550ms), the light can be turned on and off. One click touch, the light is on; once click touch, the light is off. The initial brightness of the light is fixed to 90% of the full brightness.
b) When the touch is long pressed (touch duration is longer than 550ms), the brightness of the light can be adjusted steplessly. When the touch is long pressed, the brightness of the light gradually increases. When the light is released, the brightness of the light stops at the brightness corresponding to the release time. After more than 3 seconds, the brightness of the light will not change after reaching the maximum brightness; once again, the brightness of the light will gradually decrease when the touch is long pressed. When the brightness is released, the brightness of the light stops at the brightness corresponding to the release time. If the long press time exceeds 3 seconds, Then the brightness of the light does not change after reaching the minimum brightness.
This cycle.
12. Debugging tips
If a false trigger occurs during debugging, or does not trigger, it may be caused by the following reasons:
a) The touch line is too thick
b) The touch line is too long
c) copper is not big enough
d) disturbed near the power supply end of the switch
e) Touch parameter C1 is unreasonable
Technical features:
◆TI touch input corresponds to LED light control output. There are four functions to choose from, input by T1 and T2 pins before power-on.
The status is determined. The details are as follows:
1. T1=1, T2=1 Corresponding: LED touch stepless dimming function without brightness memory
2. T1=0, T2=1 Correspondence: LED touch stepless dimming function without brightness memory faded and faded
3. T1=1, T2=0 Corresponding: LED touch stepless dimming function with brightness memory faded and faded
4. T1=0, T2=0 Correspondence: LED three-stage touch dimming function
◆The stepless dimming function of the LED touch without brightness memory and sudden darkness is as follows:
△ When the initial power-on, the light is off.
△Click to touch (touch duration is less than 550ms), the light can be turned on and off. One click touch, the light is on; once click touch, the light is off. So cycle. When the light is on or off, there is no brightness buffer. The initial brightness of the light is fixed at 50% of full brightness.
△ Long press the touch (touch duration is greater than 550ms), the brightness of the stepless brightness can be adjusted. One long press touch, the brightness of the light gradually increases, when the light is released, the brightness of the light stops at the release time, if the long press time exceeds After 3 seconds, the brightness of the light will not change after reaching the maximum brightness; once again, the brightness of the light will gradually decrease when the touch is long pressed. When the brightness is released, the brightness of the light stops at the brightness corresponding to the release time. If the long press time exceeds 3 seconds, then The brightness of the light does not change after reaching the minimum brightness. This cycle.
△Click to touch and long press to touch at any time, and the functions are not disturbed and limited.
◆Without brightness memory, the LED touch stepless dimming function is based on the stepless dimming function of the LED touch without brightness memory, and when the touch is turned on and off, The light is smoothly and smoothly transitioned from a lower brightness to the initial brightness of the light. When the touch is turned off, the light is slowly and smoothly reduced from the current brightness to the off, thereby achieving a visual buffering effect of slowly changing the brightness, thereby protecting the eyes and The effect of vision.
◆With the brightness memory, the LED touch stepless dimming function is added to the brightness memory function without the brightness and memory gradually clearing the LED touch stepless dimming function. Under the touch, the brightness will be remembered when the touch is turned off. The next time the touch is turned on, the brightness will be used as the initial brightness. In the case of power failure, the first click of the touch after power-on is turned on. The initial brightness is fixed at 50% of full brightness.
◆LED three-stage touch dimming function
△ When the power is on, the light is off.
△ Each time the touch is clicked, the brightness of the light changes in a cycle of low brightness → medium brightness → high brightness → off.
Sensitivity adjustment
The larger the capacitance value, the higher the sensitivity; the smaller the capacitance value, the lower the sensitivity.
Adjust the touch sensitivity as shown in the following table:
Media type | Capacitor type | Capacitance parameter | |
Direct touch metal casing | Polyester capacitor | 333 | 0.033uF/25V |
Acrylic glass within 3mm | Polyester capacitor | 103 | 0.01uF/25V |
3-6mm acrylic glass | Polyester capacitor | 203 | 0.02uF/25V |
6-10mm acrylic glass | Polyester capacitor | 473 | 0.047uF/25V |
Note: When the constant voltage dimmer output is connected to the LED, the upper limit current resistance must be stringed!
Current limiting resistor calculation method: R = (Vi - Vled) / Io
Among them, Vi is the input voltage, Vled is the total voltage drop of all LED lights, Io is the total current of the string. The floating range of Vi.Vled should be considered in the calculation. When the battery is fully charged, Vi will be too large. Vled will drop! Prevent over-current burning of modules or lamp beads.
