subject: The Type Of Signs More Commonly Used In The Past [print this page] Where do you plan to put LED signs? Is it in your office, business firm you handle for long, to your newly discovered and put up venture, mini kiosk, or home based office? In whatever type of institution you are planning to place the signs, you should think that it is really worth displaying for it will help you achieve the popularity you deserve and if you want to be known with that, you need to convey messages properly and you need to make things clear. Avoid LED symbols with unnecessary stuff for that wouldn't help you to be known in your chosen venture. Determine the kind of institution you have so you can properly match the signs to it. LED signs are available in an overwhelming number of sizes. How do you determine which size will be most effective in your location? Imagine the disappointment and frustration that occurs when a new sign is installed and it turns out that the letters are too small for viewers to read? Or the letters are big enough, but there isn't enough room on the display area for a complete message. So passers by only see part of what you want them to read. Understanding Viewing Distance, Character Height, Pixel Matrix and Resolution (or Pitch) will help you make an informed decision. The recommended rule of thumb is that the height of the characters/letters/text on your sign must be 1" for every 30 feet of viewing distance. The maximum acceptable distance is 50' per 1" of letter height. In other words, if you will be standing 150 feet away from a street level sign, the letters need to be 6" tall using the conservative recommended rule of thumb. Should your sign be located on a highway, 600 feet from vehicles passing at 55 mph, the letters would need to be 20" tall. The number of vertical rows will determine the number of lines of text your sign will display. An sign boards display requires 7 pixels x 5 pixels to display Standard English characters. For multiple lines of text, an eighth row is required to separate the lines. Therefore, an LED sign with 16 pixel rows will display 2 lines of text, a sign with 24 pixel rows will display 3 lines of text, 32 pixel rows will display 4 lines, and so on. And although they are housed in a plastic bulb that concentrates the light in a particular direction, unlike ordinary bulbs, LED lights do not have a filament that will get exceptionally hot or burn out. They are completely illuminated by the movement of electrons within a semiconductor material, and have the ability to last just as long as any standard transistor. Modules, switching, power supplies, fans and other components assemble cabinet. Cabinets have spec. of 4:3, 16:9 and so on. They can be customized according to customers' requirement, and can also be manufactured by standard specification. The cabinet is produced for the simplicity of Maintenance and improving the reliability
