A new model of smart street lights plus LED full-color electronic screens


Recently, major domestic mainstream media have successively reported 20 sets of smart street lights installed in Dongcheng District, Beijing. Functions in one, "intelligently made" by Shenzhen United Huiye. Among them, the most eye-catching is the blue LED full-color screen hung on the upper side of the light pole. It is understood that the LED screen is currently the highest-definition outdoor small-pitch LED full-color electronic screen with no glass design on the market, and the pixel pitch is only 3mm. On the LED screen, information such as temperature, humidity, wind speed, wind direction, and PM2.5 can be seen at a glance. At the same time, it can also display how many charging piles are on this road section, how many are charging, and how many are idle. After overcoming technical difficulties, Lianhehuiye's outdoor small-pitch LED electronic screens have become an important part of smart street lights -- the information release module -- and have successively settled in more than ten cities along with the surging smart city construction. In addition to the recent Beijing smart street light project, the current United Huiye outdoor small-pitch LED full-color electronic screens have been applied on a large scale in cities such as Pujiang in Shenzhen, Hangzhou in Zhejiang, Shenzhen and Dongguan in Guangdong, Hongze in Jiangsu, and Wuhu in Anhui. It is the first of its kind for the application of outdoor small-pitch LED full-color electronic screens. These smart street lights that landed in Beijing for the first time, the Wi-Fi signal transceiver on the top of the light pole, the smart dimming LED street light, the camera, the high-definition LED full-color electronic screen in the middle, the environmental sensor, and the public charging pile for new energy vehicles below. Citizens bring a sense of sight full of "black technology". After the LED full-color electronic screen is put into operation, these smart street lights will realize functions such as video surveillance, wireless urban WiFi coverage, PM2.5 intelligent perception, intelligent charging piles, and municipal facility monitoring through the "smart city access platform". Compared with the most popular indoor small-pitch LED screens in the industry, for most manufacturers, outdoor small-pitch LED full-color electronic screens are still in the concept stage, and few actual projects have been implemented. For the outdoor small-pitch LED full-color electronic screens commonly seen on the market, in order to ensure the service life and operation stability of the LED screen, it is often necessary to add protective glass outside the LED screen to resist water vapor, sand and dust in the outdoor environment, and car exhaust. corrosive gas. However, the existence of the glass cover not only affects the heat dissipation of the LED full-color electronic screen, which is easy to cause quality problems, but also causes superposition of mirror images, which affects the display effect. In this context, Shenzhen United Huiye's outdoor small-pitch LED full-color screen products have achieved "outer glass removal" through the national invention patent technology on the premise of ensuring a high protection level, and have broken the outdoor high-definition LED full-color screen through technological innovation. The dilemma between color electronic screen and high-efficiency protection. .
