Professional knowledge of LED lamps

1、 Basic principle of LED lamps

LED (light emitting diode) is a solid-state semiconductor device that can convert electrical energy into visible light. The basic principle is: in the semiconductor chip of LED, the p-type semiconductor and n-type semiconductor are connected to form a p-n junction. When the current acts on the chip through the wire, the electrons and holes compound in the p region and emit energy in the form of photons, that is, the light emitted by the LED lamp.

2、 Lighting characteristics of LED lamps

High efficiency: the luminous efficiency of LED lamps is much higher than that of traditional lamps, such as incandescent lamps and fluorescent lamps, which can save a lot of electric energy.

Long life: LED lamps have a long life, which can reach tens of thousands of hours, several times or even dozens of times that of traditional lamps.

Environmental protection: LED lamps do not contain harmful substances such as mercury, and are easy to recycle after being discarded, which is friendly to the environment.

Rich colors: LED lamps can directly emit red, yellow, blue, green, green, orange, purple, white and other colors of light, which is convenient for creating diversified lighting effects.

3、 Types of LED lamps

There are many kinds of LED lamps, which can be classified according to the use, shape, power, size and other factors. For example, it can be divided into household lighting lamps, commercial lighting lamps, street lighting lamps, industrial and mining lighting lamps and intelligent lighting lamps according to the purpose. According to the shape, it can be divided into bulb lamp, tube lamp, lamp, floodlight, point light source, track lamp and buried lamp.

4、 Application fields of LED lamps

LED lamps are widely used in various fields, including specialty stores and shopping malls, entertainment places, coffee shops and other leisure places, museums, art galleries and other professional places, commercial theatres, stage lighting for dance and photography in television studios, hotels, hotels, hotel lighting, meeting rooms, multi-function hall lighting, exhibitions, fashion show lighting, living room and home theater lighting, etc.

5、 Market status of LED lamps

At present, the LED lamp market has maintained a steady growth, showing some new growth points. With technological progress and market development, the industrial added value and corporate profits of the lighting industry have increased. At the same time, the output and export of LED lamps and lanterns also showed an upward trend, showing the competitiveness of China's lighting products in the international market.

To sum up, LED lamps have been widely used in the field of lighting due to their advantages of high efficiency, long life, environmental protection and rich colors. With the continuous progress of technology and the growth of market demand, the LED lamp market will continue to maintain a steady development trend.
