What Are Light Emitting Diodes (LEDs) and How Do They Work?

What Are Light Emitting Diodes (LEDs) and How Do They Work? | LED Lighting | Scoop.it
Chances are, you see light emitting diodes (LEDs) every day. They are used
to illuminate all kinds of public spaces, displays, technology screens (you
might be reading this through one right now) and they are put to myriad
uses in daily life. But have you ever wondered how they actually work to
emit light? Here is an overview of the science behind LEDs.

How Do LEDs Produce Light?

Unlike a standard (incandescent) bulb, an LED doesn't have a filament
inside of it. Instead, it uses a semiconductor that is coated with a
material to make it conduct electricity, which then produces light.
Typical LED lights use silicon crystals, which are semiconductors that have
a stable electron bond. The coating destabilizes that electron bond and
allows the crystals to conduct electricity. Negative electrons then flow
into what are called holes in P-type (positively charged) material,
emitting light as they do so. The current of electricity flows between the
anode and cathode of the LED light and its battery.

What Determines the Color of an LED?

The color of an LED is determined by the material used in the semiconductor
chip, the wavelength of the light and the band gap (the state in the
semiconductor where no electrons can exist). While many use silicon, other
materials are more common in colored LED lights. The wavelength is highest
for infrared LEDs and gets progressively lower as you look at colors moving
down the rainbow spectrum from red to violet, with white and pink having a
broader spectrum of wavelengths. Aluminium gallium arsenide (AlGaAs) is
used for infrared and red LEDs. Gallium arsenide phosphide (GaAsP) is used
in red, orange, and green LEDs. Aluminium gallium indium phosphide
(AlGaInP) and Gallium(III) phosphide (GaP)  are used in red, orange,
yellow, and green colors. Indium gallium nitride (InGaN) is used for pure
green, blue, and violet.

This is just a brief overview of how LEDs work. They are more sustainable
than standard lights and are found in a variety of brightnesses, from
the kind seen on holiday decorations to ones that light up entire
billboards.

LED Outdoor Lighting - Reasons Why LED Is the Future of Lighting for Your Home

When you try to save money the first thing that you try to cut down are your utility bills. The electricity bill is always on top of this list and you do that by trying to reduce your lights. Standard bulbs and light frames prices are increasing gradually as well. When it comes to power consumption, these lights extract a lot of power. Apart from that, they cannot tolerate voltage fluctuation. Usually, people have to replace bulbs at regular intervals. On this account, LED lights are proving to be a much better alternative.

Energy-efficiency standards with integrated LED platform offering lighting controls

Energy-efficiency standards with integrated LED platform offering lighting controls | LED Lighting | Scoop.it
Silicon Valley companies are poised to deliver smarter solutions for retailers, hoteliers and facility managers as more stringent lighting efficiency requirements go into effect. San Jose, CA -- New Title 24 lighting efficiency regulations that took effect in California this month are likely to fuel demand for hardware and software solutions that Silicon Valley companies are poised to fulfill. Changes to California's Title 24 are designed to reduce energy consumption as much as 30% in commercial and public spaces. Most of the changes rely on electronic components and software controls that are becoming more common with the adoption of LED based lighting solutions. Advances have already been made for street lighting and parking lots and further efficiency gains will be realized. But the real energy savings ahead will be the result of more stringent regulations for indoor spaces, specifically retail, hospitality and office environments, where lighting is used for a significant part of the day. While there are many changes, of the new standards, the following will have significant impact on efficiency and create new opportunities for hardware and software integration and simplification. Occupant sensing lighting controls Occupancy sensing for most spaces will be a requirement going forward. Silicon Valley brings experience with sensors and software integration that allows the familiar wall-based sensor to be incorporated directly into the light source which means fewer switches and sensors on walls and ceilings and more importantly, simpler implementation which lowers costs. Automatic Daylighting Controls The new requirements for daylighting controls apply to buildings over 5,000 square feet and require that the floor plan specify daylighting controls for 75% of the space. Previously spaces that were over 2,500 square feet only considered daylight from sky-lights in the lighting calculation. Now, controls must automatically adjust the light and must also consider light from the side, windows, when the installed general lighting uses 120 Watts or more. Additional sensing of the ambient light and control management software will make this possible. Demand Response Controls Demand response is initiated in times of extremely high demand. The lighting must be able to respond to a demand response signal and lower power levels used by lighting by at least 15% compared to the buildings usage with all lighting at 100%. In the previous code this applied to retail buildings with sales floor areas of at least 50,000 square feet. This has now been lowered to all no residential buildings with at least 10,000 square feet. Dimming of LED and other light sources Installed LED lighting in non-residential spaces of at least 100 square feet must now include dimming controls that can adjust light output levels from 100% down to just 10%. Light sources other than LED must also be dimmable but the standards for LED lighting are the most demanding. Individually, any of these factors can lead to substantial energy reductions in lighting. As a group and with the other elements in Title 24, energy savings will be substantial. California has long led the nation in energy saving regulations and it's likely that other states and countries around the world will adopt many of the standards being set in California. Companies in the hardware and software space are already developing solutions that will fundamentally change how people think of lighting, transitioning it from an energy consuming commodity to a business asset. Xicato, for example, has developed an integrated LED module  -- XIM -- that incorporates communications, controls and sensors allowing businesses to save energy and add value to the ubiquitous light-in-the-ceiling. About Xicato Xicato is enabling the Internet of Lights and empowering architects, designers and building managers to create beautiful, smart spaces people love to live and work in. We design and build intelligent LED modules that integrate the best quality and most efficient light with software, sensors and connectivity. With Xicato, spaces and buildings can be simply managed from anywhere, using any device. Xicato's headquarters and manufacturing is based in Silicon Valley and the company has offices in China, Japan, Europe and throughout the U.S. Founded in 2007, Xicato's focus on high quality light and reliability has won praise from the lighting community and end-users alike and was recently recognized as
