Working Principle and Application of Led Driver

CE LED driverworking principle:

The video input signals provided by different types of video sources are processed and sent to the LED display. The entire display usually consists of several square or rectangular dot matrixes, and each dot matrix consists of several pixels. Each pixel is composed of RGB (red, green, blue) LED tubes. By mixing the light colors of these LEDs, the required pixel information can be generated. The LED driver is equivalent to the interface between the processed video data and the colored lights emitted by the RGBLED (the image is composed of these colored lights).

In terms of color and animation, in order to achieve excellent image quality, a variety of different functions need to be integrated: high frame rate, high refresh rate, color reproduction accuracy, etc. However, the quality of the display refers not only to the image itself, but also to the overall quality of the solution, such as immunity and reliability. Therefore, all color LED displays need to choose technically sophisticated LED drivers.

Working principle and application of led driver

From the main application market of high-power LEDs-landscape lamps, to analyze the high-power LED market, the landscape lighting market as the largest application market for LED lighting, the share of about 43%. Its new round of rapid growth will definitely drive the rapid development of the overall LED lighting industry. The landscape lighting of some large and medium-sized cities such as Shanghai, Xiamen, Beijing, Dalian, and Nanchang has already reached a considerable scale, and a considerable part of the LED lighting demonstration projects have been completed. The successful completion of these demonstration projects in large and medium-sized cities coupled with the successful use in Olympic venues It indicates that the technology of LED lighting in landscape lighting has gradually matured.

Regardless of domestic or foreign, the urban landscape is a landmark product of the city, and the neon lights as landscape lighting are gradually being replaced by LED landscape lights due to energy, energy saving, environmental protection and other issues around the world. There are about 70 in all parts of the world. For 10,000 cities, if you calculate 5,000 in one city and about 1,000 yuan in one lamp, the huge economic benefits generated by these alone are unpredictable.

High bay LED driver is the core component of LED lighting. With the maturity of LED chip technology, the quality of LED light sources has been very reliable. In many cases, the failure of LED lamps comes from the driver. High-power LED drive power is an emerging industry and has not yet formed a concentrated industrial cluster, so the regionality is not obvious. And the number of companies entering the industry is not large, so the degree of competition is low.
