用LED的固有电容可以做一个串行共振的升压电路,从而产生足够点亮LED的电压。根据LED的不同颜色,高于1.6V的电压才能使其发光。阈值(或拐点)电压越高,LED波长就变得越短。所有PN结二极管(包括LED)都由于耗尽和扩散作用而存在电容。将LED的电容用于一个串联LRC(电感/电阻/电容)共振电路,就可以点亮该LED。在这种电路中,Q因数决定了LC上发生器电压的乘数。如果采用一个有足够高Q因数的 The inherent capacitance of the LED can be used to make a series resonant boost circuit, resulting in enough light LED voltage. Depending on the color of the LED, a voltage higher than 1.6V will make it glow. The higher the threshold (or inflection point) voltage, the shorter the LED wavelength becomes. All PN junction diodes (including LEDs) have capacitance due to depletion and diffusion. Use the LED’s capacitance for a series LRC (inductor / resistor / capacitor) resonant circuit to turn on the LED. In this circuit, the Q factor determines the generator voltage multiplier on the LC. If you use a high enough Q factor
