Embodiment Construction

[0008] The present invention will be further described below in conjunction with specific examples.

[0009] Such as figure 1 As shown, a new LED button dimming technology includes an integrated circuit, and the integrated circuit is equipped with a clamp diode, an undervoltage protection module), an oscillator module, a delayer, a dimming control module, and a power-on reset module. , the integrated circuit is externally connected with bypass capacitors and LED modules.

[0010] In the normal working state, this module does not work, and the voltage of the bypass capacitor is clamped at a fixed voltage by the clamping diode. When the external switch enters the off state, the terminal voltage begins to drop, and when it drops to the threshold point of the undervoltage protection voltage , the undervoltage protection logic flips, the oscillator starts to work, the delay timer starts counting, and the delay time is set internally as T. If the switch is turned on again in a sho...
