The history of LED light bulbs

They’ve been illuminating our homes since the 1970s, but do you know the captivating history behind LED light bulbs? Discover the intriguing journey of how these bulbs became the popular lighting choice on the market.

A Breakthrough Invention

In 1907, a British engineer by the name of Captain Henry Joseph Round made a groundbreaking discovery. He found a phenomenon called electroluminescence, which utilizes electrical currents or fields to produce light. Little did Round know that this invention would pave the way for the creation of LED light bulbs in the future.

From Music to Lights

Although light-emitting diodes (LEDs) gained popularity in the 1950s, they were primarily used for playing music on record players. However, progress was made when near-infrared light emission was discovered. In 1962, the first red LED was developed, followed by yellow and red-orange LEDs.

Commercial Viability

Despite these advancements, it took several stages and over half a century before LED lights became commercially viable. In the 1970s, a company called Fairchild Optoelectronics revolutionized the market by introducing LED lights for sale.

The Rise of LED Bulbs

Today, LED bulbs have firmly established themselves as the most cost-efficient, energy-efficient, and reliable lighting option. They offer a wide range of choices, including spotlights, downlights, strip lighting, and bulbs of various sizes. LED bulbs have become the preferred choice for homeowners, traders, builders, and commercial developers due to their decorative and practical nature, suiting a variety of rooms and buildings.

The Value of LED Lights

While LED bulbs may be pricier than their incandescent counterparts, they are worth the investment. Incandescent bulbs typically provide around 1,500 hours of light, while LED bulbs can provide illumination for an impressive 25,000 hours. This equates to approximately 17 incandescent bulbs per LED bulb, making LED bulbs more cost-effective in the long run.

The Future of LED Technology

LED lights have continued to evolve alongside other technological advancements. At Evergreen Energy, we firmly believe that LED bulbs are the lighting option of choice, especially due to their sustainability. These bulbs consume minimal energy and have the longest lifespan among all available bulbs, making them an environmentally-friendly choice.

The most fascinating aspect of LED bulbs is their versatility. They can provide bright lighting for bathrooms or create a cozy ambiance in hallways. As technology continues to develop, LED bulbs hold the potential to become even more sustainable, energy-efficient, and cost-effective for users.
