What exactly is the knowledge of varistor?

LEDs, commonly known as LEDs, are solid-state semiconductor devices that convert electrical energy directly into light.

The core part of the LED is a semiconductor wafer. When our current is passed, electrons and holes are directed to the quantum wire.

And then combine electrons and holes in the quantum wire, preferably in the form of billions of light to emit energy and heat, LED can do dozens of different work

These semiconductors can be found in a variety of devices. For example, these semiconductors can form a display.

Words and images, these can be transmitted from the remote control, in fact, we can see the traffic lights on the road

The ones that come out of these traffic lights are the most obvious ones of a luminous LED assembly.

The intrinsic features of these LEDs can determine that LED is the most ideal light source can completely replace the traditional light source, LED has a very wide range

Use and utility.

led

1. Small size and light weight (encapsulated in epoxy resin),

2, low power consumption, ultra low voltage (working voltage is only 2-3.6 volts);

3, long use time (the service life can be more than 100,000 hours),

4, high brightness, low consumption (has lower heat radiation than HID and incandescent lamps);

5, environmental protection (non-toxic materials, does not contain mercury, you can look back, but the red LED will contain AS, this substance contains highly toxic);

6, sturdy and durable (encapsulated in epoxy resin, stronger than bulbs and fluorescent lamps, and not easy to loose); http://

7, controllable, can help people display a variety of colors.
