Top quality led road signs External dot matrix active luminous signs, also known as "dot matrix luminous signs", "LED active luminous road traffic signs", industry abbreviation: "dot matrix signs". External dot-matrix active light-emitting signs adopt advanced digital control equipment, and LED light-emitting tubes are embedded in the information contours of the text, patterns, numbers and other information in the sign panel to realize the active light-emitting effect of the sign content. Jiangsu Tongyun Transportation Development Co., Ltd. is a manufacturer specializing in the production of active luminous signs in Jiangsu. Its technical information is as follows: (1) Technical description 1. Process description: Embed LED light-emitting tubes on the outlines of the graphics, text, symbols, etc. of the logo layout to form a linear luminous effect to meet the visual fusion effect and achieve the effect of effective visual recognition and recognition of the key information of the logo. 2. Aluminum alloy profiles are used for the encapsulation around the luminous sign, and the corners are connected by arc elbows. The overall thickness of the sign is ≤60mm (excluding the back plate fasteners), and the waterproof and dustproof measures meet the requirements of IP55. 3. The LED mounting hole on the logo page is punched by laser numerical control equipment. The diameter of the hole is regular and regular without deviation. The edge of the reflective film should be smooth and tidy without burrs. 4. The normal luminous intensity of a single LED at rated current: red≥5000mcd, yellow≥3000mcd, white≥6000mcd; LED half-strength angle θ1/2≥12.5 degrees. 5. Light control program: When the full power supply is connected, it can automatically turn on/off the sign light-emitting unit according to the surrounding light changes. 6. Visual recognition distance: dynamic visual recognition distance at night ≥ 210 meters, static

Functional advantages of LED active luminous traffic signs | Best price led traffic signs manufacturers
Best price led traffic signs manufacturers LED active light-emitting road traffic signs (hereinafter referred to as "active light-emitting signs") are more and more popular because of their superior performance and quality in special traffic environments and bad weather compared to ordinary retroreflective signs. It is widely used in traffic safety engineering. Traffic language information such as road conditions, risk factors, management instructions, etc., are reflected in the traffic sign layout through the use of standard traffic language formats, so that road traffic participants can identify them in a timely, accurate and effective manner, aiming to achieve road traffic safety, Efficient and orderly. According to the conclusion of the special study: the human body’s sense of perception is formed by the five senses of sight, hearing, smell, touch and taste, of which visual cognition accounts for as much as 83%. Therefore, as a visual carrier of traffic language, traffic signs can ensure effective recognition in all-weather and harsh environments, and their importance to drivers is self-evident. The working principle of ordinary retroreflective traffic signs: a beam of incident light illuminates the reflective material from the front, is internally refracted, and then penetrates the reflective material in the reverse direction, and reflects back in the direction parallel to the incident light, so that the light in a certain observation area The observer captures the reflected light, also known as "retro-reflection", which belongs to the category of passive light sources. Juli Technology is mainly engaged in the whole process of design, R&D, production, sales and service of road traffic luminous signs, intelligent traffic guidance screens, variable/tidal lanes, all-point information screens, intelligent composite screens and warning lamps series. The company has always Adhering to the business philosophy of "professionali

Points to consider when choosing an LED display
Now, with the advancement of social technology and the development of outdoor advertising, people's requirements for outdoor media are getting higher and higher, so large LED screens are beginning to emerge. The large-scale LED display is a perfect combination of technology and media, and its product applications involve financial securities, sports, airports, railways, stations, highway transportation, commercial advertising, post and telecommunications and many other fields. How to choose a high-quality LED large screen is a problem that many buyers need to consider. Let's talk about this problem from the key aspects of LED large screens: 1. Flatness The surface flatness of the LED display should be within ±1mm to ensure that the displayed image is not distorted, and local protrusions or recesses will cause a blind angle in the viewing angle of the LED display. The quality of flatness is mainly determined by the production process. 2. Brightness and viewing angle Brightness and viewing angle The brightness of the indoor full-color LED display must be above 1800cd/m2, the brightness of the outdoor full-color LED display must be above 5000cd/m2, and the brightness of the outdoor led strip screen must be above 2000cd/m2 to ensure The normal brightness of the LED display is required, otherwise it will be difficult to see the displayed content because the brightness is too low. The brightness is mainly determined by the quality of the LED die. The size of the viewing angle directly determines the audience of the LED display, so the larger the better, the size of the viewing angle is mainly determined by the packaging method of the die. Three, white balance effect White balance effect The white balance effect is one of the most important indicators of the LED display. In color science, pure white will be displayed when the ratio of the three primary colors of red, green and blue is 3:6:1. If there is a slight deviation in the actual rati

Things to pay attention to when choosing LED display
The LED display has the advantages of ultra-high brightness and seamless splicing. If the LED pitch is small, the picture will be clearer and more delicate. Among the many material display screens, LED display screens are relatively environmentally friendly and energy-saving. If there is a demand in this regard, how to choose a display? 1. Seamless splicing, large screens are all spliced together, but there are many materials for splicing screens, and the advantage of LED displays is that splicing is seamless. If it is an LCD splicing screen, splicing is very obvious, so seamless splicing is considered one of the advantages of led display screens. 2. Super high brightness. If the LED display is different from other displays, it must be the ultra-high brightness of the LED display. LED display screens can also display normally under direct sunlight, becoming the dominant outdoor display screen. Brightness is high; outdoor displays are generally large screens, so there are certain requirements for brightness, LED displays are very suitable. 3. Customized size, various shapes. The led display screen can be made into various sizes, and the shape of the display screen can be flexibly changed according to different use environments. The special-shaped led screen can also be customized to attract pedestrians with a peculiar appearance. 4. Energy saving and environmental protection, the energy consumption of LED large screen display is about 30% lower than other displays of the same area.
