AskShenzhen led display on modular design: AnsShenzhen led display because of its eye-catching , flexible content and other characteristics, have been increasingly used in advertising , information dissemination, traffic signs and other public places , and achieved good results . Shenzhen led display digital display is divided into two and the number of dot-matrix display , this article discusses only dot matrix display . Currently led display in Shenzhen are basically first by user requests, it needed to build production plants , must be repeated each time the circuit design and mechanical structure , resulting in a waste of resources, and if the users needs change , changes will be very difficult . Shenzhen led display for an existing design to be repeated , high cost , we propose a modular design led large screen display, can achieve flexible configuration , offline operation , special effects display, and briefly describes the hardware structure and software features.In fact, regardless of the size of the display , the principle is the same , so they could design a standardized , modular led display in Shenzhen , will different needs, only a combination of the corresponding module can be proud of . This article describes is a modular Shenzhen led display, you can change the size of the flexibility required, and can be run independently from the computer , you can achieve as blinking, scrolling display effects. Whole -screen refresh rate flickering occurs less frequently asked questions , in this design because the module is divided into small , is no longer a problem.The actual display modules are small led driver board the same size , capable of driving led arrays with basic display features, and can receive data and commands from the control module , in addition to some common display such as blinking, scrolling , etc. are also included in the display module. Existing GB lattice Store 16 * 16 24 * 24 two kinds of , taking into account the convenience of writing software and hardware capabilities, we put the display module as a 16 × 16 matrix size. The control module is responsible for controlling each module , each module to send data and commands. The control module lattice data stored information to be displayed , each display module timed pass . The control module also comes with a small keyboard and universal asynchronous serial port , which can be used to operate the keyboard can also be used to control a computer , the computer can also be used to update the control data within the module .
AskChoose from nine LED light source: AnsAs the herd market , as consumers, to choose LED remains calm, scientific analysis , the choice of the best cost-effective light sources and luminaires , LED Here are a few basic properties :1 , the brightness of the LED brightness , different prices . LED for LED lamps shall comply with the Laser Class Class Ⅰ standards.2 , antistatic ability antistatic ability of the LED, long life, and therefore higher prices . Typically the static than 700V LED can be used for LED lighting .3 , consistent with the wavelength of the wavelength of the LED, the same color , the same color as requested , then the price is high . No LED spectral separation device manufacturers is difficult to produce pure colors .4, the leakage current LED is one-way conductive light , if there is a reverse current is called leakage, leakage current is large LED, short life, low prices.5 , the use of different light angle LED luminous angle is not the same. Special light-emitting angle , the higher the price . If all diffusion angle , the higher the price .6 , different quality of life is the key to life, life is determined by the light fades . Light decay, long life, long life , high price.7, the LED light-emitting body is a wafer chip , different chips , prices vary widely . Japan, the United States more expensive chips , chip prices generally lower than that made in Taiwan and Japan and the U.S. .8 , the size of the size of the wafer to wafer side expressed great quality LED chips are better than small chips . Chip size is proportional to the price of the same .9 , colloidal ordinary LED colloidal generally epoxy resin, plus a UV resistant and fire retardant in LED expensive, high- quality outdoor LED lighting should be UV and fire . Each product will beThere are different designs, different designs for different purposes , the reliability of the design aspects of LED lighting include: electrical safety , fire safety, applicable environmental safety , mechanical safety , health and safety,Safe use of time and other factors . From electrical safety point of view, should be consistent with relevant international and national standards. Since LED is a new product , China lags behind national standards , but the state provides product qualification testing . With international safety certification ( such as GS, CE, UL , etc. ) and national product quality certification of LEDLighting the price is higher , because these products are designed to be safe and reliable . Consumers should carefully note that the certificate of authenticity , there are international and national product safety certification certificate manufacturersNot much. From a health aspect , the use of non-toxic materials designed product prices to be high, especially indoor LED lighting, do not choose the smell of cheap LED lighting, LED manufacturers currently only a fewIs produced with non-toxic materials , the method can be directly used to identify each nose , the smell of the product is lower than the price of many odor -free . Professionals need a similar analysis of lead, mercury , cadmium and other toxins. From fitnessLook with the environment safe, reliable dust-proof design, material fire , UV, anti- low temperature cracking price LED products is high.
AskHow to tell the quality of LED lights?: AnsLook material, LED unit board sheet: Some LED unit board manufacturers to price competition, the use of low-cost single-sided fire-retardant paper or fiberboard panels madeLED lights for the PCB board. Because, full fiberglass PCB board too expensive. In effect beginning no difference, lucky can hold a half months, Under normal circumstances within a year will be because of moisture, UV damage, oxidation and other reasons break, causing the entire LED unit board scrapped. High qualityLED unit board must use double-sided full fiberglass PCB board, although the cost is high, but the quality is guaranteed.IC: IC devices used to observe whether the brand consistency.Lamp beads and chips: the naked eye can not see, can only be achieved through aging tests.
