The propagation speed of the diode light-emitting tube will emit light, and the forward voltage drop is higher than that of ordinary diodes. The downstream voltage is generally 5V, while the ordinary attenuation step-down voltage drop is 0.7V, and the back drop speed is reduced. Some even-numbered V will not emit light after conducting.
The core light-emitting part of the light-emitting diode is a chip. The chip is a communication method. It has a property: low-current light-emitting, which mainly converts energy into light.
Two bows, one bow, and in addition, there are early vacuum electronic connections; it is an electron that can attract current in one direction. According to the direction of the applied voltage, the electronic device has the characteristics of unidirectional current. Generally, the appearance is a p-type semiconductor and an n-type semiconductor. At the formed pn junction interface. The three-dimensional interface layer formed on the surface constitutes self-built. When the applied voltage is equal to zero, because pn
The junction carrier concentration difference, diffusion current, and self-built electrons are constantly updated with excitement, which is also an accompanying characteristic under normal conditions.
