Energy conservation is a hot topic for a reason. Energy-efficient lighting options help you save money on your electric costs and reduce your reliance on nonrenewable energy sources.
LEDs, the most energy-efficient lamps on the market, are beginning to appear in hardware and home-goods shops alongside incandescent and compact fluorescent bulbs.
They are, however, a mystery to many, as their internal workings vary significantly from those of regular bulbs. LEDs are becoming an increasingly common alternative to incandescent and compact fluorescent lights due to their long life and low operating costs.
LEDs are now one of the greenest light sources available due to technological advancements. It makes them one of the most environmentally friendly light sources available. However, have you ever asked what the acronym LED stands for?
A diode is an electrical device or part that contains two electrodes (an anode and a cathode) from which current flows in a single direction (in through the anode and out through the cathode).
Diodes are typically constructed of semi-conductive materials such as silicon or selenium – substances that conduct electricity under some conditions but not others (e.g. at certain voltages, current levels, or light intensities).
In the 1960s, LEDs were introduced as thrilling yet costly electronic components for use in portable calculators and other related instruments.
LED technology evolved by research and development, becoming more effective and affordable, until it entered its present state. LEDs are also used in a variety of lighting systems that cover the visible, infrared, and ultraviolet light spectrums.
Affordable 12V LED lamps, for example, are often used in place of incandescent lighting in residences, businesses. And places of business because they are more energy-efficient, last longer, are more mechanically stable and are cleaner.
When an electrical current is applied to a diode, it excites the electrons inside, causing them to emit photons. Which we perceive as light. The color of the light is determined by the energy difference in the diode’s semiconductor. This means that LEDs can quickly and brightly generate a rainbow of colors while using relatively little energy.
LEDs have proved to be the most energy-efficient bulbs available in the search for energy-efficient lighting. According to the US Department of Energy, Energy Star-rated LEDs use at least 75% less energy than conventional incandescent bulbs and last 25 times longer.
LEDs also outperform CFL (compact fluorescent lighting) bulbs in terms of efficiency, owing to their twice the lifetime. LEDs are more effective than incandescents and compact fluorescent lights (CFLs) because they direct light rather than reflecting it in all directions, and they do not need or emit large quantities of heat. Incandescents and CFLs all emit the majority of their energy as heat — 90% and 80%, respectively.
