The idea of using LEDs for a full spectrum display never got too far until the invention of the white LED, which occurred shortly after high-efficiency blue LEDs appeared. These devices tend to be pricey and difficult to manufacture at large scales.
However, as the manufacturing process continues to mature, so does LED lighting. LED technology continues to mature, and a wide range of uses for LEDs have been discovered, including:. LEDs will continue to be used in a wide variety of products, and new uses are being rolled out all the time. OLED technology uses electroluminescence, meaning millions of tiny pixels create light depending on how much electric current they receive. Warm LED colors, such as red and yellow, are considered best for sleeping because eyes are less sensitive to these colors, and their "color temperature" is lower than that of the sun.
However, blue light can disrupt your internal clock and disturb your melatonin production, making this cooler color a poor color to surround yourself with when trying to sleep.

Typically, diodes have been used in many technologies such as radios, televisions and computers as an electrical component for conduction.
See References 1. Connecting a diode to an electrical current excites the electrons within the diode, making them release photons, which we see as light. The color of the light is a direct result of the energy gap in the semiconductor of the diode. This means that LEDs produce a spectrum of colors easily and brightly while using very little electricity to do so. In the search for energy-efficient lighting, LEDs have proven to be the most efficient bulbs available.
Energy Star—rated LEDs use at least 75 percent less energy than traditional incandescent bulbs and last 25 times longer, according to the U. Quality LED light bulbs last longer, are more durable, and offer comparable or better light quality than other types of lighting.
Check out the top 8 things you didn't know about LEDs to learn more. LED is a highly energy-efficient lighting technology, and has the potential to fundamentally change the future of lighting in the United States. By , the majority of lighting installations are anticipated to use LED technology, and energy savings from LED lighting could top TWh annually by , equal to the annual energy output of more than 92 1, MW power plants.
Key differences include:. LED lighting is available in a wide variety of home and industrial products, and the list is growing every year. The rapid development of LED technology has resulted in increased product availability, improved manufacturing efficiency, and lower prices. Below are some of the most common types of LED products.
The high efficiency and directional nature of LEDs makes them ideal for many industrial uses. LEDs are increasingly common in street lights, parking garage lighting, walkway and other outdoor area lighting, refrigerated case lighting, modular lighting, and task lighting. Because LEDs are small and directional, they are ideal for lighting tight spaces such as countertops for cooking and reading recipes. Since there can be variation in light color and directionality, it is important to compare products to find the best fixture for your space.
Recessed downlights are commonly used in residential kitchens, hallways, and bathrooms, and in a number of office and commercial settings.
