What are the functions of speed radar warning sign
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

What are the advantages of LED pedestrian light 1. High efficiency and energy saving This is determined by the principle of light emission. General lighting lamps convert electrical energy into heat energy and then excite them into light energy. A large amount of heat energy is wasted, while LED lights directly convert electrical energy into light energy, thus saving most of the energy. 1000h consumes only a few kilowatts of electricity, which is only 1/10 of incandescent lamps and 1/4 of energy-saving lamps. 2. Green and environmental protection The light-emitting principle of ordinary energy-saving lamps generally contains mercury, which is difficult to be discharged once it enters the human body. If it is improperly handled during recycling and scrapping, it will cause the mercury to diffuse into the air, pollute the environment and endanger health. LED lights are made of non-toxic materials, which are easier to be recycled and reused. 3. Long service life The LED is encapsulated in epoxy resin, which is sturdy and durable, not afraid of vibration, not easy to break, and it is a semiconductor chip that emits light, there is no filament burn, light attenuation, etc., and the service life can reach 60,000 hours to 100,000 hours. .content_box { border: 1px solid #333; padding: 20px; } .content_box img { max-width: 100%; height: auto; } .content_box h3 { text-align: center; } KITE LED Street Light HYLAS LED Street Light SQUARE Canopy Light If you are interested in led pedestrain light,You can browse related products and initiate consultations on our website.

Application of integrated pedestrain light in life
"Red light, please wait. You have crossed the line, please return and wait. " A few days ago Shanghai launched the country's first set Picture of a new pedestrian crossing reminder system Compared with traditional red and green indicator lights This new type of street crossing reminder system Not only has the LED light reminder function picture Through the perception system Pictures of pedestrians who run red lights at any time It can be described as a combination of safety and technology In addition to voice and light prompts, the system is also equipped with a high-pixel camera, which integrates the functions of capturing and investigating pedestrians who violate the signal lights, and publishes illegal photos on the LED electronic screen in real time, playing a deterrent effect.

Application of led direction guidance sign
There are many manifestations of self-luminous signs, so let's pick a few common methods for your reference. Back light structure Backlighting is commonly known as backlighting. The light source is installed in the back of the character and in the shell, and it is a kind of luminous character that shines on the wall. The backlit logo is beautiful and elegant, with strong three-dimensional effect, soft light without glare, and strong plasticity. It can be installed on the outdoor door or indoor image wall according to different methods. The large-size back-illuminated logo is very eye-catching, and can generally be used as a LOGO sign for the company's entrance. The small-scale backlit logo helps to enhance the warmth of the environment, and is suitable for the entrance of hotel rooms, cafes, and small restaurants. The material of the back luminous characters is generally stainless steel, aluminum, titanium, acrylic, crystal, iron sheet, etc., the most common is stainless steel. After the metal has a built-in light source, it can be installed suspended from the wall or mounted on the wall, and the light is directly irradiated on the installation surface. That can achieve a hazy beauty. Application of led direction guidance sign you can browse related products and initiate consultations on our website.
