Application prospect of LED in traffic field

LED display is widely used in many fields of social economy. In many application fields of LED display, display of traffic information is one of the important applications of them, especially in the information age, the development of intelligent transportation system, in service for public transportation field, the release of information services has become the important content of all kinds of information display equipment become the airport, train station, dock, the bus station, highway, city roads, parking lot for the public release of information, the leading means, among them, LED display with high brightness and high reliability are favored.

LED is one of the means of intelligent transportation system

Intelligent transportation system (IntELligent Trans-portation System) refers to the intelligent information system which provides the comprehensive traffic information service for the public or special audience group. Intelligent transportation information service system including information source, information processing and information display part, which is mainly released by various multimedia display devices, such as LED display, LCD display, CRT display, PDP display etc..

With the development of modern information display technology, CRT, LCD, PDP, LED, EL, DLP and other information display products are formed. Throughout all kinds of display products, 14 inches LCD is dominant, 14 inches -32 inches is led to CRT, 40 inches -70 inches or 100 inches will be the PDP market, more than 100 inches, either indoors or outdoors, LED display has become the mainstream product in absolute advantage.

In the transportation industry in our country, relatively speaking, the airport flight information display system, a display terminal in general are more advanced in the system; railway passenger information display system started earlier, the traditional means to display LED and CRT, has developed rapidly in recent years, the system and the automatic system on the passenger transportation network, performance the intelligent level of the system is excellent; the rapid rise of road traffic induced, in the development and improvement process, due to the environmental characteristics of the road traffic, LED display has become the main means of information display.

LED display is the main carrier of road traffic guidance system

Road traffic guidance system is an important traffic information service system of intelligent traffic management systems in modern city, real-time processing and analysis of dynamic traffic condition, by the command control center decision makers through manual or automatic mode, release and display of traffic information and road condition, reduce the degree of blockage, improve the road capacity.

In practice, the traffic guidance information for the general public is released in the outdoor environment, due to the high brightness characteristics of LED display, various forms of LED display as the main carrier of traffic guidance information. Common traffic induced LED display traffic induced LED display (variable intelligence board), traffic induced path display board, parking signs, variable logo, etc..

Traffic information for outdoor LED display, according to the actual situation of road traffic management and traffic guidance information display, has the following characteristics in the use of specific functions: high brightness, perspective is reasonable; display color with red, green and yellow; the display brightness can be automatically adjusted; all-weather work, complex environmental conditions; remote control, intelligent detection; security, real-time, accuracy and reliability. LED show broad prospects in the field of transportation

With the development of material technology, the application scope of LED has been widened. Look forward to the application of LED display in the field of transportation, there are several aspects worthy of attention:

Strong demand for traffic lights

Super bright, high power LED devices have been widely used in urban traffic lights. LED signal lamp with its high brightness, high reliability, low cost, long life and other characteristics, get the favor of urban traffic management department. From the national perspective, the development of urbanization and municipal road construction, increasing the number of new traffic junctions, the current use of traditional traffic lights have been replaced by LED lights. Prediction of domestic road traffic lights LED market capacity should be in the billions of dollars. In addition, the highway lane lights, airports, railways, shipping and other areas of the signal, the identification of lights, there is a great market potential. Highway LED variable information boards have become standardized and standardized products

Highway LED variable information boards, variable speed signs and other products has become the product of highway construction and standardization of the standard, need to complement existing roads, new roads have standard facilities requirements, related products industry standard has been officially promulgated. Expected annual highway variable intelligence board, variable speed limit signs and other display products in the market capacity of 300 million yuan to about 500 million yuan.

Broad application prospects in the automotive field

According to research statistics, LED used as the main car brake lights when the response time is faster than the traditional incandescent lamp 80ns, on the highway will increase the safety of 4 meters to 6 meters. Due to the good seismic performance, energy saving, environmental protection and other characteristics of LED, automotive lighting, lighting and other applications will have good development. At present, many domestic and foreign automobile manufacturers have begun to use LED brake lights, instrument lights and lighting.

Urban road traffic guidance, signs, etc. in the gradual expansion of road traffic induced LED display in various cities are growing rapidly, the rapid development of product technology. In terms of product types, traffic induced LED display is still the mainstream products, but a variety of simple, economical and practical variable traffic information logo products will be
