LED Lights
Let’s embark on a fascinating journey into the world of LED lights and delve into the intriguing technology that powers them.
At the core of an LED light lies a diode, which consists of three essential components: a positively charged anode, a negatively charged cathode, and a semiconductor material sandwiched in between them. This semiconductor material, often made from indium-gallium-nitride, holds the key to the magic of LED lights.
When electric current passes through the anode and cathode, electrons fill the holes in the semiconductor, giving rise to a mesmerizing phenomenon known as electroluminescence. This process is responsible for the generation of light in LED bulbs.
The concept of electroluminescence can be traced back to 1907 when Henry Joseph Round made a remarkable observation of a faint light emanating from Silicon Carbide. However, it wasn’t until 1961 that researchers succeeded in creating LED lights that emitted bright enough light for practical applications, marking a significant milestone in LED technology.
The advancements didn’t stop there. By the mid-1970s, LED lights capable of emitting a spectrum of colors, including yellow, red, and green, had been developed, opening up new possibilities for lighting solutions.
The journey of LED innovation continued throughout the subsequent decades. In 1994, Shuji Nakamura made a groundbreaking breakthrough by inventing a bright blue LED light, expanding the color palette of LED technology. This discovery paved the way for further advancements, as scientists explored coating the blue light-emitting chip with fluorescent phosphors. The result was the creation of vibrant white light, which has become the hallmark of modern LED bulbs.
The remarkable evolution of LED lights exemplifies the creativity and unwavering commitment of researchers and engineers to push the boundaries of lighting technology.
While the benefits of LED lights are undeniable, it’s essential to address any potential drawbacks that may exist. Let’s delve further into the subject and examine the safety considerations associated with LED lights, including radiation, blue light, and other potential risks.
LED Lights and Radiation
When it comes to LED lights, their energy efficiency is often hailed as a major advantage. Saving on electricity bills is undoubtedly a positive outcome, but there is a lesser-known side to this efficiency that deserves attention.
The issue lies in the concept of dirty electricity, which some of you may already be familiar with. Let’s explore this further. Power lines transmit a specific amount of power, typically 60 Hz AC electricity in the United States and 50 Hz AC in many other parts of the world. While energy-efficient devices require less electricity to operate, the power outlet continues to receive the same amount of power. The excess energy is not utilized and instead returns to the home’s wiring, creating what we call dirty electricity.
Dirty electricity can pose problems, particularly for certain individuals. Symptoms such as headaches, dizziness, and nausea have been associated with exposure to this type of electromagnetic radiation. It’s worth noting that dirty electricity falls under the category of extremely-low frequency (ELF) EMF radiation, which has been linked to childhood leukemia.
Fortunately, there are ways to measure the levels of dirty electricity emitted by LED lights and other devices in your home. In the following sections, we will delve into the process, providing you with valuable insights and guidance.
LED Lights and Blue Light
When it comes to LED lights, the negative effects extend beyond just dirty electricity. Let’s revisit how these modern light bulbs are made. The foundation of an LED is an ultra-blue light emitting chip, which is then coated to produce a bright, white light.
Although LED lights come in various forms, the blue-light rich ones are particularly prevalent in homes and retail spaces. These lights are often labeled as “cool,” but it’s important to recognize that excessive exposure to blue light can have adverse health effects.
Several government agencies worldwide, such as the French Agency for Food, Environmental and Occupational Health & Safety, acknowledge the potential risks associated with blue light. They recommend limiting exposure to cool-white light due to the potential for retinal damage, which can lead to Age-Related Macular Degeneration (AMD). Research has shown that this damage can occur from prolonged dim exposure or short bursts of bright blue light.
It’s worth emphasizing that children, whose eyes are still developing until the age of 20, are particularly vulnerable to blue light damage. Night shift workers, pregnant women, and seniors also fall into this susceptible category due to various factors.
In addition to vision problems, blue light exposure from LED bulbs has been associated with migraines, seizures, neurological issues, visual disturbances, nausea, and eye strain. Furthermore, blue light disrupts our natural melatonin production, which can disrupt our sleep-wake cycles.
While blue light is not a form of electromagnetic radiation per se, it is crucial to acknowledge its potential dangers in relation to LED lights.
Safer Alternatives
When it comes to finding safer alternatives to LED lights, there are options available for various devices. Let’s explore some of these alternatives:
GE Incandescent Globe Soft White Bulbs
Instead of using an LED light bulb, you can consider using GE Incandescent Globe Soft White Bulbs. These traditional incandescent bulbs may not be as energy efficient or long-lasting as LEDs, but they are more affordable and produce less dirty electricity. Moreover, the soft white light they emit minimizes the amount of harmful blue light. By replacing your home’s LED bulbs with soft white incandescent ones, you can significantly reduce your exposure to LED-related blue light.
Jall Wake Up Light Sunrise Alarm Clock
If you’re looking for an alternative to an LED alarm clock, the Jall Wake Up Light Sunrise Alarm Clock is worth considering. While it does have a red-based LED time display, you have the option to turn off the display at night if you find the light disruptive.
