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.

How traffic lights work | high power traffic light
The traffic lights are equipped with induction control, and vehicle detectors are set on the entrances of intersections. The traffic signal timing scheme is calculated by a computer or an intelligent signal control machine. It is a control method that can be changed at any time with the traffic information detected by the detector. The basic method of induction control is induction control at a single intersection, referred to as single-point control induction control. Single-point sensing control can be divided into semi-sensing control and full-sensing control depending on the setting of the detector. Regarding the transportation system as an uncertain system, it can continuously measure its status, such as traffic flow, number of stops, delay time, queue length, etc., gradually understand and master the object, and use the difference to change the adjustable parameters of the system or produce a control . Extended information: history At the beginning of the 19th century, in York City in central England, red and green outfits represented the different identities of women. Among them, the woman in red indicates that I am married, while the woman in green is unmarried. Later, horse-drawn carriage accidents frequently occurred in front of the Houses of Parliament in London, England, so people were inspired by red and green outfits. On December 10, 1868, the first member of the signal light family was born on the square of the House of Parliament in London; The lamppost designed and manufactured by De Hart, a British mechanic at the time, was 7 meters high, and hung a red and green lantern-a gas traffic signal light. This was the first signal light on a city street. At the foot of the lamp, a policeman holding a long pole pulled the belt to change the color of the lantern as he wanted. high power traffic light

The working principle of led display (1) System composition This system is composed of computer special equipment, display screen, video input port and system software. Computer and special equipment: Computer and special equipment directly determine the function of the system, and different types can be selected according to the different requirements of users on the system. Display screen: The control circuit of the display screen receives the display signal from the computer, drives the LED to emit light to produce the picture, and outputs sound by adding power amplifiers and speakers. Video input port: Provide a video input port. The signal source can be a video recorder, a DVD player, a camera, etc., and it supports multiple formats such as NTSC, PAL, and S_Video. System software: Provide special software for LED playback, powerpoint or ES98 video playback software. (2) System function The system has the following functions: With the computer as the processing control center, the electronic screen corresponds to a certain area of the computer display (VGA) window point by point, the display content is synchronized in real time, the screen mapping position is adjustable, and the size of the display screen can be easily and freely selected. The display dot matrix adopts ultra-high brightness LED light-emitting tubes (red and green dual primary colors), 256 levels of gray, 65536 color combinations, rich and vivid colors, and supports VGA 24-bit true color display mode. Equipped with graphic information and 3D animation playback software, it can play high-quality graphic information and 3D animation. The playback software can display information in more than ten forms, such as covering, closing, opening the curtain, alternating colors, and zooming in and out. Using special program editing and playing software, you can edit, add, delete and modify text, graphics, images and other information through different input means such as keyboard, mouse, scanne

How to wire the led billboard light? What to do if the led billboard is not bright?
1. How to wire led billboard? 1. Plug wiring: The plug outlet is to open the outlet hole from the middle of the plug pieces at both ends of the led linear lamp, which will be very convenient to install. The plug outlet cannot be seamlessly connected, and the aesthetics is slightly inferior to that of the bottom outlet. 2. Side wiring: Choose one of the two sides of the led linear lamp to punch an outlet hole equivalent to the wire diameter. The waterproof pairing wiring is connected to the circuit board from this hole. Its advantage is that it can be seamlessly connected. , The brightening effect has no dark areas, and the installation is very convenient. 3. Bottom wiring: the bottom wiring is drilled from the bottom of the two ends of the led linear lamp aluminum profile with a wiring hole equivalent to the wire diameter. The principle is the same as that of the side, which can make the wiring hidden in the bottom position, which is more beautiful. high. 2. What to do if the led billboard is not bright? 1. Leakage. There is a slight leakage in the installation site. When creating the word, the line does not run smoothly, the connector is poorly connected, the second word starts to have a leakage part, and the wiring cabinet tape is opened and grounded. 2. Because the transformer power supply is too small, use a normal necessary transformer. Please use a different transformer according to the size of the word. We use two power supplies (transformers), for example, one word for the first four, one word for the remaining four, and one power supply for the remaining four. Two wiring can solve this problem. It is best to arrange a bit thicker. 3. The arrangement of the lights is uneven. Maybe there are too many LEDs on the road. This can't be done too much. Please contact the manufacturer of the lamp for how many specific belts each has. There are too many straps in some places, too bright in some places, and too little in some places, and the b
