Electricity has an important effect on human life. It is the basis of energy acquisition, transformation, and transmission, electronic information technology.

LED (semiconductor light-emitting diode) packaging refers to the packaging of light-emitting chips, which is quite different from integrated circuit packaging.

The basic structure of LED is a semiconductor P-N junction. Experiments show that the temperature of the P-N junction will rise when the current flows through the LED device. Strictly speaking, the temperature of the P-N junction region is the junction temperature.

In today's era, advanced science and technology must be the mainstream and direction of development, but also the inevitable product of the development of the times.

In recent years, with the rapid development of led technology, the scope of application in the domain of lighting is also expanding. LED landscape lighting, LED indoor lighting, or LED large screens have gradually come to the public's attention.

The light slowly transforms from natural sunlight and moonlight at night to ancient kerosene lamps, Edison's tungsten filament bulbs, and nowadays LED lights.

More and more people initiate using LED lights for lighting. Whether it is day or night, you can see LED lights.

The light-emitting diode, like the semi-conductor laser, is a PN junction that emits light by injecting electrons into it from an external power source.

So far, the lighting field that LED enters is only the so-called particular lighting field, such as car lighting, urban landscape lighting, museum cultural relic art lighting, and backlight lighting.

Today, people have changed from the days and nights of the past to the era of light everywhere.
