LED means light emitting diode. LEDs are semiconductor devices that produce light through a process called electroluminescence. When an electric current is applied to a semiconductor material, visible light is emitted. As such, LEDs contrast with solar cells, which are used to convert visible light into electricity in solar panels. We have known the technology behind LEDs for years. LED technology of led lighting manufacturer has helped astronauts land on the moon and creates portable AM radios by contributing to the development of solid-state transistors.
In 1960s, a young scientist working at General Electric developed the first LED. They were first used by companies as circuit board indicator lights and became known for their durability and energy efficiency. Many municipalities have used second generation LEDs, available in the 1980s and 1990s, as a replacement for traditional incandescent street lighting. Some people have started experiments to use them as a replacement for exterior fluorescent lights.
Main advantages of LED lighting
LEDs are tightly packed with enough energy and consume up to 90% less energy than incandescent lamps. Because LEDs consume less energy than light bulbs, energy costs are drastically reduced, and therefore less money is spent on monthly energy bills. The long life of the LED saves costs on maintenance and replacement.
More secure with LEDs:
Security is perhaps the most overlooked advantage when it comes to LED lighting. The biggest danger from lighting is the release of heat. LEDs emit little heat forward, but conventional lamps, such as incandescents, convert more than 90% of the total energy used to directly convert them to heat. This means that only 10% of the energy that drives the incandescent bulb is actually used for light. Also, LEDs consume less power, so they work well in low-voltage electrical systems. These are generally much safer if something goes wrong.
LEDs produce directional emissions:
LED technology emits only 180 degrees. Other types of lights emit 360 degrees around the light source. 360-degree radiation requires accessories to reflect and/or redirect light. This generally increases the cost of the system and inevitably leads to losses. That is, the devices are not always as efficient as others. Think of a light that emits light on the ceiling. This is the standard lamp. The problem is that you are trying to light the room, not the ceiling. LEDs completely solve this problem and provide savings on the overall energy efficiency of the system.
The lifetime of LED lighting products
The life of an LED lighting product is defined differently than the life of other light sources, such as compact fluorescent and incandescent (CFL). LEDs generally don’t “burn out” or fail. Instead, “lumen depreciation” occurs in which the brightness of the LED decreases slowly. Unlike incandescent lamps, the “lifespan” of an LED like led panels is determined based on a prediction of when the light output will decrease by 30%.
