Why do light-emitting diodes glow

Light-emitting diode it is a solid electroluminescent semiconductor device that converts electrical energy into light energy, the core part of the light-emitting diode is composed of p-type semiconductor and n-type semiconductor wafer, there is a transition layer between the p-type semiconductor and n-type semiconductor, called the p-n junction. It is mainly composed of five parts: bracket, silver glue, wafer, gold wire, epoxy resin.

Is a light-emitting diode a semiconductor?

Light-emitting diode is also known as LED. it uses a fixed semiconductor chip as the light-emitting material, so it is a semiconductor. Light-emitting diodes are relatively more environmentally friendly and energy efficient than traditional lamps and lanterns, with high color rendering. Semiconductor light-emitting diodes have a simple structure, small size, small operating current, easy to use, low cost, so the application in the photoelectric system is extremely common.

LED lamp beads light-emitting principle

The terminal voltage of the PN junction of led lamp beads constitutes a certain potential barrier, and when the forward bias voltage is added the potential barrier drops, and most carriers in the P and N regions diffuse to each other. Because the electron mobility is much larger than the hole mobility, so there will be a large number of electrons to the P region diffusion, constituting an injection of a few carriers to the P region. These electrons and the valence band of the hole complex, complex energy obtained in the form of light energy released. This is the principle of PN junction luminescence.

Light-emitting diode cold and hot light source difference

Light emitting diode how to distinguish between cold light source and thermal light source, we can not only from the definition to distinguish. In fact, what we call cold light source does not mean that the process of LED light-emitting beads do not produce heat, but refers to the way LED light-emitting beads are not converted from thermal energy to light energy. Incandescent lamp is the process of converting electrical energy into heat energy, and then heat energy into light energy. Heat energy loss is high, luminous efficiency is low, in accordance with the development trend of LED white light; LED lamp beads white light we can regard it as a cold light source.

What is the operating current of LED lamp beads in milliamps?

LED lamp beads use low-voltage power supply, the supply voltage is between 2-4V, depending on the product, so drive it is a safer power supply than high-voltage power supply; especially suitable for public places;
