LED devices have very high requirements for the conversion efficiency, effective power, constant current accuracy, power life, and electromagnetic compatibility of the LED drive power. A good drive power must take these factors into consideration, because the drive power is in the entire LED lamp. The role is as important as the human heart. The main task of the LED driver is to convert the AC voltage into a constant current DC power supply, and at the same time complete the matching with the LED voltage and current. Another task of the LED driver is to make the load current of the LED controlled at a pre-designed level under the influence of various factors.
There are conditions for the LED electronic display to emit light. The forward voltage is applied to both ends of the PN junction, so that the PN junction itself forms an energy level (actually a series of energy levels), and electrons jump at this energy level and generate photons to emit light. Therefore, the voltage applied across the PN junction is required to drive the LED to emit light. Furthermore, because LEDs are characteristic-sensitive semiconductor devices with negative temperature characteristics, they need to be stabilized and protected during the application process, thus giving rise to the concept of LED “drive”.
Anyone who has been in touch with LEDs knows that the forward volt-ampere characteristics of LEDs are very steep (the forward dynamic voltage is very small), and it is more difficult to supply power to the LED. It cannot be directly powered by a voltage source like ordinary incandescent lamps. Otherwise, the voltage With a slight increase in fluctuation, the current will increase to the point that the LED will be burned out. In order to stabilize the working current of the LED and ensure that the LED can work normally and reliably, various LED drive circuits have emerged.
a senior statistician at the Service Industry Survey Center of the National Bureau of Statistics, said: my country’s manufacturing industry has become more stable and improving. He said that since the beginning of this year, as the effects of policy measures such as stabilizing growth, adjusting structure, benefiting people’s livelihood, and preventing risks have gradually emerged, domestic demand has gradually recovered, coupled with the continuous recovery of the external economy, external demand has improved, and positive factors for economic development have increased. As a member of my country’s manufacturing industry, the LED display control card industry will also ease its market competition pressure to a certain extent.
Secondly, my country’s urbanization process is accelerating, and the market for LED electronic display control cards in second- and third-tier cities is huge. The city white paper recently published by the National Academy of Sciences mentioned that my country will complete the urbanization coverage rate of about 60% by 2020, and the technology of LED wireless control card manages the entire project chain. It is estimated that by 2020, the consumption output value of LED products by urban households will reach 500 billion yuan.
The acceleration of urbanization will drive the development of infrastructure in urban and rural areas, stimulate investment, and stimulate consumption. The LED industry, as a link in the industry chain of construction and automobile industries, will have more market demand along with the development of other industries, which will stimulate the development of the LED industry and inject fresh vitality into the LED industry.
As a member of the urban development process, the emergence of LED electronic displays makes the city play a different style. The construction of township is inseparable from the improvement and popularization of public infrastructure, environment, management and other aspects. It will also face more energy consumption problems. Therefore, LED applications have become the main product to beautify the scenery and reduce energy consumption in the process of urbanization. All in all, the domestic market has a long history and will usher in a broader space. Domestic LED display companies, as local companies in China, must consolidate their foundations and develop more long-term.
