What are LED Signs and Lights, Really?

LED stands for Light-Emitting Diodes. Electrons moving through a semiconductor material are the elements responsible for producing the light that we see on LED bulbs and LED signs. If well designed and well-manufactured, LED signs and lights are easy to operate and safe to touch – they are actually cool to the hand. Solid-state lighting (SSL) is a form of lighting technology that LED signs are a part of. This innovation in lighting technology may very well revolutionize lighting as we know it. LED lighting is energy efficient, which helps users save money by reducing electricity costs and demand.

LEDs do not scatter light which is what makes them more energy efficient as compared to incandescent and fluorescent lights. However, LED signs and lighting do have limitations. LED lights are still in its infancy stage and manufacturers are still in the process of finding a way to produce brighter LED bulbs to make these energy efficient items well-suited for general or ambient lighting. A single fixture may actually contain hundreds or even thousands of tiny LED bulbs just to make it brighter. Additionally, LED signs and bulbs are a tad bit more expensive that other bulbs on the market, but it’s worth the price since products using LED bulbs and lights will last longer, making them cheaper in the long run.

LED bulbs are now being applied to a lot of appliances and equipment – from digital clocks and watches to LED signs and LED open signs. At first, semiconductor material was costly, but its price has dropped, making LED products more affordable to the public. This price drop opened the door to more exciting, energy-efficient and environment- friendly lighting technology. Nowadays, LED light bulbs are virtually everywhere. Consumers, both individuals and businesses can purchase LED light bulbs and LED signs online and locally. With the advent of digital signage, LED lights are now the main source of light for signs and billboards.
