Light emitting diodes have several advantages over traditional incandescent lamps. The first is that the LED without a filament will burn out, so its lifespan will be longer. In addition, the small plastic light bulb of the light-emitting diode makes the light-emitting diode more durable and durable. It can also be simpler and more suitable for current electronic circuits. The emission process of traditional incandescent lamps involves generating a lot of heat. This is completely a waste of power. Unless you use a lamp as a heater, as the vast majority of useful current does not directly generate visible light. Light emitting diodes declare very little heat, and relatively speaking, the more electricity they emit directly, the greater the reduction in demand for electricity.
Until now, light-emitting diodes are still too expensive for most lighting applications because they are made using advanced semiconductor materials. The price of semiconductor devices has significantly decreased in the past 10 years, but making light-emitting diodes a more cost-effective lighting choice for a wider range of applications, light-emitting diodes will play a greater role in world technology in the near future.
Free electrons pass through the P-type layer through the diode and fall into empty electron holes. This includes falling from the conduction band to a lower orbital function, so electrons release energy in the form of photons. This will occur in any diode, when the diode is composed of a certain substance, you can only see photons. In regulating the atoms of silicon diodes, for example, when electrons fall into relatively short distance atoms, they are arranged in this way. Result: Due to the low electronic frequency, it is impossible for the human eye to see.
