Do you know what are the advantages of LED displays?
The LED display screen is equipped with a full-color display screen, and the introduction of higher-quality imported LED chips makes the screen image high-definition, uniform in color, low power consumption, lightweight, thin screen layer, and wide-area viewing angle, so it fails. Small probability, easy maintenance. It mainly adopts the multimedia display card PCTV card that integrates various functions, with more excellent performance, more advanced acquisition methods, accurate video capture, and Studio editing software that matches the display card. DVI interface technology is more advanced. There is no need for A/D and D/A conversion, which ensures the integrity of the picture image, reduces the possibility of details, and completely reproduces the computer image on the display screen. DVI can support all display modes, ensure the stable and reliable data display and also have a variety of integrated functions. The indoor full-color system is used to alleviate the hidden dangers existing in the system display and transmission of a large amount of complex data, and full-color restoration is fully performed. Use the chip to complete the task of data distribution and display, convert the received data to pulse output, convert from 8-bit display data to 12-bit PWM, and upgrade to 4096-level grayscale control, realize non-linear 256-level visual grayscale display on the screen, and fully create a complete True color visual enjoyment.

How much do you know about LED displays
LED display is a kind of flat panel display, which consists of small LED module panels, and is used to display various information such as text, images, and videos. The LED display screen is an electronic display screen composed of LED dot matrix. By changing the red and green light beads on and off, the screen display content forms such as text, animation, pictures, and videos are converted in time, and the component display control is carried out through the modular structure. LED electronic display integrates microelectronics technology, computer technology and information processing. It has the advantages of bright colors, wide dynamic range, high brightness, long life, stable and reliable operation. LED displays are widely used in commercial media, cultural performance markets, stadiums, information dissemination, news releases, securities trading, etc., which can meet the needs of different environments.

Do you know what led high bay light is
Led high bay light is a miner's lamp produced with high-brightness LED light source instead of traditional lamp beads as luminous body, and with lithium-ion battery. Compared with the traditional miner's lamp, the product has the advantages of small size, light weight, high efficiency and energy saving lamp. This product can be used for portable lighting in various underground mining operations, tunnel operations, marine operations, maintenance operations, outdoor sports, hunting night fishing, inspection and exploration, soldier equipment and other places. When the led high bay light is used underground, the charging hole should be covered to prevent dust or water from entering the charging hole. Blockage or corrosion of the charging hole will cause the miner's lamp to fail to charge and be scrapped. The miner's lamp should pay attention to maintenance during use. Protect the lamp face glass to maintain the best lighting effect. When cleaning, the miner's lamp should not be put into water, and should be wiped with a damp cloth. Do not over-discharge for a long time during use, otherwise the battery life will be affected. The room temperature of the charging room should be in the range of 0 to 35°C. If it is not within this range, the battery may heat up, which will affect the performance of the battery and shorten the battery life. The led high bay light should be used within the cycle life of the battery, and those that reach the service life should be forced to be scrapped.

Lightning protection knowledge of LED traffic lights |200mm led traffic light
Walking on the streets and alleys of urban roads, the most familiar thing is the alternating flashing of various traffic lights. Busy cars moved forward and stopped regularly amid the flashing of red, yellow and green lights. The traffic signal lights erected on the pillars of the intersection are to promptly indicate relevant information to the passing vehicles. Because of its high erection position, it is easy to be damaged by direct lightning. The power line is introduced by the signal control machine, and there is no signal line. There is a threat of direct lightning strike and power line overvoltage. Therefore, it will directly strike over voltage and power line. Voltage is the focus of protection. The pillars of the traffic signal lights are installed with current-limiting lightning rods for direct lightning protection. The top of the bracket and the base of the current-limiting lightning rods must ensure reliable electrical and mechanical connection. The bracket itself is grounded or the 40×40 flat steel is connected to the grounding grid of the bracket frame itself. The grounding resistance must be less than 4 ohms. Use over-voltage protectors as power protection at the power leads of traffic lights and signal controllers, and pay attention to waterproof, moisture-proof, and dust-proof. The over-voltage protectors are connected to the grounding pole of the main frame with multiple copper wires of no less than 25mm2, and the grounding resistance is less than 4 ohms. Grounding protection. For a standard crossroad, the pillars and front-end equipment are scattered, and it is difficult to achieve single-point grounding. In order to ensure the equipment working grounding and personal protective grounding, only vertical grounding bodies are welded under each pillar. The mesh structure method is the multi-point grounding method, which is mainly aimed at the lightning protection requirements such as the gradual discharge of the incoming waves. To ensure pers

What are the core functions of led active light-emitting signs? | Led sign
Led sign The led active light-emitting sign is to embed LED light-emitting tubes in the text, numbers, letters, symbols, and borders of the logo page, and light the LED light-emitting tubes through external mains or solar power supply to realize the key information elements of the logo page. A luminous traffic sign. LED active light-emitting signs are widely used in traffic safety engineering because of their unique core functions. So, what are the main core functions of led active light-emitting signs? (1) Long-distance visibility The led active light-emitting sign has super long-distance visibility. Generally, the static visual recognition distance is greater than 250 meters; the dynamic visual recognition distance is greater than 210 meters. Through long-distance visual recognition, the driver can find the traffic language information displayed by the sign, which can win more time for correction of driving behavior and improve the overall traffic safety of the road section. (2) Wide-angle visibility The led active luminous sign board does not need to rely on the illumination of the high beam. Through its own luminous effect, it can achieve a large angle of visibility, especially the signs installed on the top of the gantry and on the side of the wider road. The ordinary signs are due to The reflection limitation of the retro-reflected light cone often results in scotopic vision. The led active light-emitting sign can achieve a large viewing angle close to 90 degrees. (3) Enhance the warning effect The led active light-emitting sign can use the preset control module to realize the dynamic flashing effect of the light-emitting light source of the sign, enhance the warning effect and easy capture of the sign, and improve the driving safety of the drivers on the road section. (4) Light penetration in severe weather The led active light-emitting sign board adopts super light-transmitting LED light-emitting tube. In the harsh traffic environment such as rain,
