SMD LED opens a new era of outdoor full color display
Figure 1 LED display trends
Traditional solar system includes so many parts: traditional lamp ( or LED lamp), Solar Panel, lead-acid battery, controller, solar panel brackets, battery cabinets. The volume is very large, therefore freight charge is very high, and labor cost of mounting is also very high. But Ruifeng`s Solar Smart integrated solar LED Street Lights solve all the above problems and troubles. Ruifeng has designed and developed a unique [SolarSmart"-all in one Integrated solar street lighting module, Fit and Forget built with intelligent Microcontroller charge controller system, comprising High Efficiency 12W Integrated Solar Street Lights 12W Integrated Solar Street Lights,12W Solar Street Lights,Solar Led Street Light,Solar Street Lamp Yangzhou Bright Solar Solutions Co., Ltd. , https://www.solarlights.pl
At present, LED display screens have been widely used in commercial media, cultural performance markets, sports venues, information dissemination, news release, securities trading, etc., to meet the needs of different environments. The development prospects of LED displays are extremely broad, and are developing towards higher brightness, higher weather resistance, higher luminous density, higher luminous uniformity, high reliability and full color. The development of the display screen complements the development of its LED light source device. The LED device is gradually transitioning from the traditional in-line package to the SMD package, and has emerged in the outdoor full-color display market.
First, the development of LED display market
1. LED display market development trend and application field LED display development has gone through three stages: monochrome screen, two-color screen and full-color screen, among which, full-color screen is divided into in-line RGB full color and SMD RGB three-in-one Full color two forms. The introduction of blue LEDs in the 1990s played a decisive role in the realization of full-color displays. Figure 1 shows the development trend of LED displays.
