Advent of LEDs does not mean just mere emergence of an alternative lighting technology in the world of illuminated signs. This new technology paves a revolutionary change in a way that the industry never experienced it before. Be it electronic billboards, illumination source for channel letters, text messages… LEDs now rule the world of glow signs and displays. SIGN & GRAPHICS observes this technological revolution sweeping across the domain of illuminated signage.
Being the most consistent, significant and distinguished lighting source for illuminated signs, LEDs prevail against all odds which we usually faced earlier while using traditional or usual lighting devices or technologies. Today, LEDs undertake a big leap upon the areas of electronic texts, graphic messages, video walls and others applicable both in indoor and outdoor parameters.
Advanced efficiencies
It is quite clear to almost everyone in the industry today that LEDs have unique advantages over the conventional lighting technologies like tube lights, CFL, etc used as illumination sources in neon signs and all. Also the other major distinguished features of LEDs include its small size, low power consumption (voltage efficiency) and sturdiness (life span) as they could last upwards of 60,000-70,000 hours.
Performance efficiencies and application versatilities of LEDs have been a moving target since technological improvements in this lighting source get improved day-by-day. Compared to the day when LEDs were first introduced in the Indian signage market, cost of this lighting component is now dramatically descended and it makes the technology one of the most sought-after illumination sources for glow sign systems or solutions.
Unique market
Now that every single attribute of LED has built up special interest to the sign community, this lighting technology has become a critical device for glow signs by creating its own niche market where a league of manufacturers and distributors have set their pace forward to deliver the best of LED technologies, components and services. Currently, several leading LED manufacturers like SAMSUNG, LG, Osram, Phillips, etc produce spectrums of LED models of different luminosities (brightness), designs, colours for varied applications, whether it could be for indoor or outdoor.
Luminosities of LEDs are technically based on the manufacturing process involving the use of semiconducting materials like aluminium, indium, gallium and phosphide which create variations in colours like orange-red, orange, yellow and green lighting units. Indium and gallium-nitride compounds create blue, blue-green, true-green and when combined with a yellow phosphor, white.
Applications unlimited
As long as innovative display systems of outdoor advertising companies are concerned, LED-based billboards become one of the most preferred advertising mediums these days. LED manufacturers, sign makers, fabricators and others in this domain now-a-days take keen observation of the ongoing trends as well as the needs and requirements of designs and dimensions of glow billboards/video walls and other innovative or custom display systems installed on high-rise buildings, hotels, restaurants, highways and other strategic locations.
Some leaders in the contemporary Indian signage market foresee a future boom in LED applications in the glow sign segment. Opinions pour in as a matter of fact that the sky-rocketing development in the LED-based glow sign items in the country would surely bring in an international
standard which can convert the Indian cities like what it glows around the cityscapes of Las Vegas, New York and Cape Town, etc.
