Shandong, known as the originator of the semiconductor lighting industry, has seen the “energy-saving pioneers†in the provinces and cities. On the one hand, the relevant departments of our province began to promote the use of LED (light-emitting diode) lamps in an all-round way, and strive to become the absolute protagonist of the future urban bright project; on the other hand, the provincial government began to brew "to accelerate the development of semiconductors in our province. The Opinions of the Lighting Industry, with the help of Inspur Group and other big names to integrate the semiconductor lighting industry chain, and strive to lead this emerging industry.
LED lights can be seen everywhere
The vigorous renovation of the "big living room" lighting renovation project in the provincial capital came to an end. The reporter saw at the renovation site that the lamps around the spring and the lotus fountain were changed into a bundle of LED lights. Construction workers told reporters that this new light fixture is not afraid of water, there are more than one hundred illuminators on a board, the luminous intensity is increased, and there is anti-glare function. Of course, its most direct effect is energy saving. In the night lighting project of Quancheng Square, among the newly installed thousands of lamps, LED cold light accounts for about half.
According to experts from the Provincial Energy Conservation Office, the LED light sounds strange, but it has been around us. In addition to the "big living room" landscape lighting, such as the night lights on the Jinan viaduct, the provincial city "first screen", the hotel's exterior night lights, the securities company's display, and even some high-end computer screens, mobile phone displays, etc. They are all masterpieces of LED. When it comes to specific applications, this expert told reporters that LED is currently mainly used in these areas: public display screens have become the fastest growing area of ​​LEDs; the emergence of color screen mobile phones has made LEDs show their talents; The new "Shantou" for sale; interior lighting and landscape lighting, let LED enter the lives of the people.
What is the LED light?
As the provincial "big living room", why does the night lighting renovation project mainly promote LED lights? Dr. Qin from the National Key Laboratory of Crystal Materials of Shandong University told reporters that LED lights are the future development trend of lamps and lamps, and they are also worthy of promotion.
According to the expert, the “big living room†decorated with LED lights is not only more embarrassing, but also an “energy-saving pioneerâ€. LED is the abbreviation of semiconductor illumination, which is a solid-state illumination method composed of light-emitting diodes, relying on "electron-hole" composite illumination. Since there is no heat loss, the power conversion efficiency is much higher than that of a normal light bulb.
The seven advantages of LED lights have created this "energy-saving pioneer." The LED lamp is safe. The semiconductor light-emitting diode is a solid-state device of organic resin and semiconductor material and metal material package. The structure is firm, and it will not be loose or broken during normal use, and the illuminant is a cold light source, and the driving circuit is not high. Voltage; long service life, LED life is tens of thousands of hours, incandescent lamp life is only a few hundred hours; semiconductor power of micro-power illumination is much higher than other light sources; LEDs have various colors, can meet white light The requirements of special lighting; convenient driving and regulation; small size and light weight; discarded components without heavy metal pollution, which is conducive to environmental protection.
These technological advantages have determined that semiconductor light-emitting devices will eventually develop into new lighting sources. It is estimated that if one-third of the traditional lighting in the country is replaced by LED, the annual electricity consumption is equivalent to a Three Gorges hydropower station; in addition, it is also characterized by environmental protection and long life, which is called the second time in the history of lighting. revolution".

Electronic Components Transformer
Transformer is a device that USES the principle of electromagnetic induction to change the ac voltage. Its main components are primary coil, secondary coil and iron core.The main functions are: voltage transformation, current transformation, impedance transformation, isolation, voltage stabilization (magnetic saturation transformer), etc.According to use can be divided into: power transformer and special transformer (electric furnace change, rectifier, power frequency transformer, voltage regulator, mining, audio transformers, intermediate frequency transformer, high frequency transformer, impact transformer, instrument transformer, electronic transformer, reactor, transformer, etc.).The circuit symbol T is often used as the beginning of the number. Examples: T01, T201, etc.
