Giới thiệu Mô-đun điều khiển độ sáng đèn LED PWM
FeaturesThe touch dimming module can realize the touch switch control and brightness adjustment of the LED light. 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. The touch function can be realized under the protection of medium (such as glass, acrylic, plastic, ceramics, etc.), and the safety is high.
3. The application voltage range is wide and can be arbitrarily selected between 2.4 and 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 more than ±2KV; in the case of close-range, multi-angle mobile phone interference,
Touch response sensitivity and reliability are not affected.
6. Installation: no direct contact with copper foil, dimming through acrylic glass or plastic of 3mm or more.
7. Use: It can control LED modules, lamp strips and other products. Suitable for indoor table lamp, LED lighting dimming, DIY lamp dimming to modify the best accessories.
8. Function: Single-line touch, using the principle of capacitive touch, the sensitive touch tentacle can be. The default is the LED touch-infinite dimming function with switch function, dimming function and brightness memory fade-out. It lights up slowly when the light is turned on, and slowly darkens when the light is turned off, 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 attaches one side of the copper foil to the side of the outer casing.
