How to Understand LED Lights:
- Compare LED lighting to compact fluorescent bulbs. Compact fluorescent bulbs are not as efficient as LEDs, they take longer to light up and they contain mercury. LEDs contain no toxic elements. And, according to Amber Angelle, writing for "Popular Mechanics," LEDs are one of the most promising light sources out there in terms of efficiency, longevity and reliability
- Figure the cost benefits. LED lights are more expensive initially, but after five to 10 years, homeowners recoup the costs. As of 2010, an outdoor LED spotlight runs you about $100 compared to $7 for a regular light spotlight bulb, according an article by Elisabeth Rosenthal and Felicity Barringer in "The New York Times." But, scientific advances are happening monthly, Brian Owen, a contributor to the LED trade magazine, said in "The New York Times." These advances are sure to bring the prices down. One advance is growing LEDs on silicon wafers instead of the more expensive sapphire, like what is currently occurring
- Contrast how much longer LED lightning lasts than incandescent bulbs. You'll find LEDs last so much longer that it changes light bulbs from cheap, disposable energy-wasters to semipermanent fixtures in your household. LED lights can last 22 years. They are, basically, an install-and-forget type of purchase. Compare LED lighting to a fluorescent bulb that might last you 3,000 hours. The LED lasts more than 100,000 hours, according to Rosenthal and Barringer. Angelle estimates that LEDs can last for 50,000 hours
- Convert to LED lighting, and you can decrease carbon emissions from electric power lighting by up to 50 percent in 20 years, according to Rosenthal and Barringer. This type of conversion would be, perhaps, the most cost-effective approach to tackle wasted energy
- Program the LED lighting to perform tricks. They can get brighter as someone walks under the light, or they can flicker to guide paramedics to an emergency at your house. And, because LEDs do no emit ultraviolet light, you can sit outside on your patio in the summer without LEDs attracting bugs
What are LED Lights?
- LED stands for "light-emitting diode."
- LED lights are extremely small semiconductor diodes that are capable of creating light
- The light that is created by any given LED can be of any color and can even be ultraviolet or infrared
- The light that is created by an LED light depends on the material that is used to make the semiconductor and the current that is run though it
- There are many different types of LEDs, including miniature ones, as well as high-powered LEDs and multicolor variations
How Do LED Lights Work?
- LED lights work very similarly to standard light bulbs except for the fact that LEDs are much smaller and contain no filament
- Instead of a filament, an LED creates light using nothing but the movement of electricity along the path of its semiconductor
- As the electrons stream across the semiconductor, they create electromagnetic radiation. Some forms of this electromagnetic radiation can take the form of visible light, which humans can perceive via sight
What Are LED Lights Used For?
- There is an almost inexhaustible supply of applications for LED lights, some of which have already been realized and others that are currently being implemented
- Within the world of electronics LED lights are used in traffic lights, screen displays, computers, brake lights and any other application which requires a bright, inexpensive and long-lasting light
- They also are used in the burgeoning field of photonic textiles and as a source of light in places where high temperatures cannot be tolerated. Indeed, LED lights are one of the most important technologies in contemporary electronic products and many such products would be impossible without them
The LED Bulbs Effects:
- The LED bulbs give bright light and save money from cost utility
- Light up your stair and reduce stumbling at night with these amazing LED bulbs
- Power saving and long life-span LED bulbs are perfect for 24/7 constant use
- The LED bulbs for both main and moonlight illumination are possible
Colour Temperature:
- The photos below were taken in a dark room, without pre-setting the camera or editing the photos afterwards
- Different colour temperatures of the LED bulbs can be seen on the trim of the terracotta pot and on the cactus
- The first photo the object was illuminated with cool light. The cool light is the brightest
- The second photo natural white was used, it is similar to sunlight
- The third photo the warm white can be seen, which is similar to the color of tungsten lighting and halogen lights
The Kelvin Scale:
Colour temperature has important applications in lighting. The colour temperature of a light source is usually measured in kelvins (K) at which the heated black-body radiator matches the colour of the light source is that source's colour temperature
- Higher colour temperatures (5000 K or more) are "cool" (green-blue) color, and lower colour temperatures (2700-3000 K) "warm" (yellow-red) color
