"Necessity is the mother of invention". Before the invention of an LED, people used to emit light by the means of incandescent lamps.
(prHWY.com) February 21, 2012 - California, CA -- Human's necessity for a luxurious life craves for more and more invention of advanced technology and in this way comes the invention of LED DISPLAYS. LED is abbreviated as light emitting diode. They are the advanced version for LCDs. Let us have a glance of how these LEDs are useful for us. They carry out their presence in the industry of aviation lighting, automotive lighting, advertising, general lighting and mainly in our traffic signals giving out smart and sustainable lighting.
Through the effect of electroluminescence these LEDs function and emit light that is in the form of photons, when this LED is forward biased the electrons travel through and combine with the electron holes which release energy in the form of light. The common usage of LED can be best found in traffic signals which use outdoor LED signage. All the messages are given through LED moving signs.
In shopping malls, theatres, airports, metro railway stations etc these LEDs find a various application that displays the message through LED message boards through which the visitors counter can also be noted in a day and so on. The important specifications that you need to take care before purchasing a LED is that it should be fast switching, should consume low energy, should retain for longer life span that is they do not burn as they do not contain any filament therefore working out for more life time thus saving huge energy consumption. These LED message boards are used in hi-tech trams, ferries and buses to denote the source and destination of travel with different intended colors. This programmable LED sign board is programmed to different applications in such a way by maintaining efficiency and reliability at user friendly and acceptable levels. There is also an availability of alphanumeric LED displays in seven segment format which were in wide use but with the invention of liquid crystal displays with greater flexibility it reduced the popularity of alphanumeric and numeric LED displays.
More or less effectively these LEDs found a prominent place in the advertising industry. At high tech malls and complexes or in the presence of a busy street road we found their advertisings scrolling representing their brand name on the digital billboards. This way of digital billboard advertising achieved great craze for the owners who thinks that this way of advertising can attract customers well and popularize their brand successfully from their competitors.
Before investing your amount in LED signs better check out their experience in industry and how well they maintain their relationships and whether you get the specifications of size, color, pixel and positions as per your order or not. Go on for a factory tour and seek their advice which would be useful for you and first design your initial budget under proper guidance and finally place your order and enjoy a fine installation.
