How LEDs Have Changed The Lighting Industry Forever
The lighting industry came into existence since the first electric bulb invented with a view to brighten up the lives of people in a dramatic way. A few decades later and with a few more improvements, the industry advanced when tungsten filament bulbs were invented that went on to power households and jumpstart new businesses for over a century. One can safely say that the incandescent bulbs revolutionized the world.
But later on, these electricity-sapping glass orbs fell out of favor with the environmentally-conscious governments and customers and were replaced by Compact Fluorescent Lamp Bulbs or popularly known as the CFL bulbs. The CFL bulbs spelled the end of light bulbs. These bulbs were the first major alternative to regular halogen or incandescent light bulbs in the mid-2000s but later on, the CFL bulbs failed to meet the government standards for energy efficiency and gradually phased out from the whole new era for energy-efficient lighting.
And then came into relevance, the LED, or the Light Emitting Diode bulbs-- a better quality and more energy-efficient cousin of the CFL. This marked a drastic change in the lighting industry.
We live in a world where conservation of resources is the need of the hour and one such technical innovation to help conserve our environment, was the introduction of LEDs into our households and industries. LED lights are the latest technology in energy-efficient lighting. These bulbs use a light-emitting diode technology hence are far superior to the incandescent, fluorescent or halogen lamps in terms of lifespan, energy efficiency and ecologically friendly, which makes them a perfect retrofit. Let’s have a look at how they changed the face of the industry with its distinct features.
Let us have a detailed look at those features
LED bulbs use 30-75% less power than other light sources and have an efficiency level of 80-90%, meaning that almost all the energy is converted into light and is not lost as heat, the electricity bills from usage of air conditioners, fans, or any other cooling device diminishes by a great extent.
Ecologically Friendly - LED bulbs are free from toxic materials such as mercury, arsenic or toxic gases, hence they do not require special handling. Instead, they are designed to be 100% recyclable. This helps in reducing our carbon footprint.
Effectiveness - LED lights have lesser glare because these lights are designed to focus light into a specific location or direction, without relying on an external reflector which means these lights are good for reading and driving at night.
20-50% less heat generation than incandescent, halogen, and fluorescent bulbs. This is due to the infrared radiation and more. This keeps them cool and safe to touch while installation. Also, they are operational in extremely cold or hot temperatures.
Reaction Time - LED bulbs are dimmable and they can be switched on and off instantly, which means they come handy in infrastructure projects. These bulbs are at full brightness the moment they are switched on and do not flicker.
LED lights are made using solid-state components, which are more resistant to shocks and vibrations. They are far less likely to be damaged, when compared to traditional light sources, with delicate components, such as filaments or glass tubes. This is why LED tube lights last a very long time. These lamps also have heat dissipation elements like heatsinks and cooling fins, meaning, the more the dissipation, the longer the lamp life.
Size And Color - LED bulbs are available in a variety of shapes and sizes, but they are generally smaller can one square inch. This means they can be used in a variety of applications besides general lighting, such as for indicator lights in electronic devices. They are also available in different color options, making it attractive too.
Long Life Span - LEDs have another environmental trick up their sleeve: they last far longer than most other light sources. The incandescent bulbs last around 1000 hours before burning out, while comparable CFLs last 8000 to 10000 hours. LEDs do not burn out in the same way but simply get dimmer over time, and when they fall to 70% of their initial brightness, their useful life is considered over. A good LED light has a useful life of between 30000 and 50000 hours, meaning less are thrown away and hence less are manufactured.
Low Maintenance -
Other light sources require a lot of maintenance and upkeep, but LEDs require very little. This is because of their long lifetime, and the fact that they are not as easily damaged as other light sources.
LED bulbs are costlier when compared to incandescent bulbs and CFLs but in the long run, the LED light bulbs prove to be cost-effective because of the numerous benefits they have over other light sources.
Way Of Living - Every organism on this planet experiences periods of day and night and our circadian rhythms are largely controlled by it. We have evolved not only to love light but to need light. We see the best in light and experience changes in our mood and emotions due to the change in lightings. LED proves to be the best to suit the aesthetic as well as the necessity mindsets of people with different tastes. Hence, these lightings influence the way of modern life.
