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

The role and characteristics of the walk-in vms machine Through virtual machine software, you can simulate two or more virtual computers on one physical computer. These virtual machines work exactly like real computers. For example, you can install operating systems, install applications, and access the network. Resources and so on. For you, it is just an application running on your physical computer, but for an application running in a virtual machine, it is a real computer. Therefore, when you perform software evaluation in a virtual machine, the system may crash; however, it is only the operating system on the virtual machine that crashes, not the operating system on the physical computer, and use the "Undo" of the virtual machine ( Restore) function, you can immediately restore the virtual machine to the state before installing the software. Features 1. Multiple operating systems can be run on the same PC at the same time, and each OS has its own independent virtual machine, just like an independent PC on the network. 2. When running two VMs on Windows NT/2000 at the same time, you can talk to each other, or you can talk to virtual machines in full screen mode, but at this time another virtual machine is running in the background. 3. Install another release of the same operating system on the VM without repartitioning the hard disk. 4. Share files, applications, network resources, etc. between virtual machines. 5. You can run C/S applications, or you can use all the resources of another virtual machine on the same computer. .content_box { border: 1px solid #333; padding: 20px; } .content_box img { max-width: 100%; height: auto; } .content_box h3 { text-align: center; } Trailer VMS-Type A0 Trailer VMS-Type A1 Trailer VMS-Type B1 If you are interested i

What are the functions of speed radar warning sign Warning signs are conventional emergency equipment on cars, and their appearance is generally triangular, so they are also called triangle warning signs. The warning signs must strictly comply with the requirements of the Road Traffic Safety Law and be a passive reflector made of plastic reflective materials. The principle is that when car owners encounter sudden traffic accidents on the road, they use the reflective properties of warning signs to remind other vehicles to avoid second accidents. The function of the warning sign: The reflective part of the warning sign is made by using the retro-reflective principle of high-refractive glass beads and the micro-diamond-shaped reflection principle of the reflective crystal lattice, and is made by advanced processing after focusing. It can reflect the distant direct light back to the luminous place, and it has good retroreflective optical performance no matter in day or night. Especially at night, it can display the same high visibility as during the day. Warning signs made of this high-visibility reflective material can be easily spotted by night drivers no matter if the user is in a remote place or under the interference of light or scattered light. The emergence of reflective materials successfully solved the night driving problem of "seeing" and "being seen". Note: When selecting warning signs, editors must choose products with guaranteed quality, because within a safe distance, whether later vehicles find the warning signs in time is the key to avoiding rear-end collisions. It is recommended to choose a foldable reflective warning sign, because the foldable reflective warning sign should be placed 50 meters away from the rear of the vehicle when the vehicle appears to be gross* and needs to be stopped for inspection, to remind the driver to slow down in advance; when not in use, The foldable warning sign will not take up much space in the car. .content_box {

The difference between LED stadium floodlight and floodlight
LED floodlights are also called spotlights, projection lights, spotlights, etc. They are mainly used for architectural decoration lighting and commercial space lighting. They have heavier decorative components and have round and square shapes. Generally, the reasons for heat dissipation must be considered, so its appearance is still somewhat different from traditional floodlights. LED flood light classification: 1. Rotationally symmetrical shape The luminaire adopts a rotationally symmetrical reflector, and the symmetry axis of the light source with rotationally symmetrical light distribution is installed along the axis of the reflector. The iso-intensity curves of this type of lamps are concentric circles. When this type of spotlight is illuminated by a single lamp, an elliptical spot is obtained on the illuminated surface, and the illuminance is uneven; However, in the case of multi-lamp lighting, the light spots are superimposed on each other, which can produce satisfactory lighting effects. For example, hundreds of rotationally symmetrical floodlights are commonly used in stadiums, and they are installed on high towers around the stadium to obtain high illuminance and high uniformity lighting effects. 2. Two symmetrical plane shapes The iso-intensity curve of this type of projector has two symmetry planes. Most luminaires use symmetrical cylindrical reflectors, and linear light sources are installed along the cylindrical axis. 3. A symmetrical plane shape The isobaric intensity curve of the luminaire has only one symmetry plane (Figure 2). The luminaire adopts asymmetrical cylindrical reflector or symmetrical cylindrical reflector plus a grid that restricts light. The most typical is the sharp cut-off block retracted light distribution. This kind of light intensity distribution single lamp can obtain a more satisfactory illuminance distribution. 4. Asymmetrical shape The iso-intensity curve of this type of luminaire does not have a plane of symmetry. M
