There are an abundance of applications available for LED lighting. Some of these include:
LEDs in Industry:
Industrial sized buildings such as an airport/factory are running lights for 24 hours 7 days a week. This means that the electricity usage is very high. The fact that the ceilings in these large industrial buildings are very high means that light maintenance procedure is timely therefore costly. Not to mention the cost involved in the replacement of the bulbs themselves. The use of LED lights would improve this situation dramatically. LEDs will use a fraction of the energy of the lights that came before them. The fact that LEDs are very energy efficient means that they are also reliable. LEDs last several times longer than your average halogen or even CFL. Therefore maintenance costs are at a minimum.
LED’s in Retail:
Nowadays people like to get away from the house and go out and explore. Shops, especially clothes shops, are always on the list for people on a day out whether it’s to purchase or browse, shops will always attract crowds. Therefore shops have to be visually appealing to the public. A great way to improve the aesthetics of a shop is to use lighting to your advantage. With LEDs coming in an abundance of colours it’s a great way to entice buyers in. It sets a tone for the shop. LEDs are also used in retail for display purposes. The fact that most LEDs expel their light linearly means that they are good for showcasing a product whether it’s a watch or a bag.
LED’s in Outdoor Spaces:
LED’s provide an excellent way of illuminating our urban environment. LED’s are very versatile as they can be a variety of colours. This gives architects, landscapers and designers the ability to create a mood or ambiance. For example...

...ly an insulator which allows no current to pass. To allow current to pass the electrons need to be fit to pass from one region to another. If a positive voltage is connected to the P-Type region and a negative voltage is connected to the N-Type region then this will create an electric field which allows the free electrons to go towards the positive region and repel form the negative region.
This is the basic operation of a diode, but when do we start to achieve light? LED’s perform the same way as a normal diode in fact most normal diodes are light emitting diodes but the light produced is so small it can’t be seen. LED’s operate in state known as forward biased. This means that electrons and holes are constantly moving towards the depletion region and being replenished by the connected voltage. The process of the electrons and the holes meeting creates the light.
One of these new innovations is glow in the dark road markings. This new technology uses solar power obtained from the road throughout the day to “charge” the photo-luminising powder that is the glow in the dark lights. Expensive lighting will be replaced with this more cost efficient option that can glow up to eight hours a night. This innovation can already be found on the N329 highway in Oss, Netherlands. Other advancements in lighting to come include wind powered lights and interactive lights. Wind powered street lights will be powered by the gusts of wind created when a car passes by, reducing the need to burn fossil fuels to power the lights. Interactive lights will be turned off but as a car approaches they light up, then fade back away as the car passes by. Smart new technology has the future of roadway systems
Such as in Fig. 5 where we can see a blue backlight that illustrates a lone figure walking down a path and a lit streetlight at the front depicts a mood of isolation and evokes uneasiness in the audience as though the figure is being
All are relevant to the film that I will be applying the study of lighting
In the development of expanding, Southern Light a private cable company plans on extending its fiber-optic services from the Gulf Coast to Huntsville, Alabama. Southern Light is the Gulf Coast’s leading provider of fiber optic networks and high-volume transport solutions. Southern Light markets affordable, high-bandwidth services over their own fiber optic network. In this research, I will discuss the history and main operates of this private business, then I will identify and analyze the four factors of production of Southern Light fiber. Next, I will identify and analyze the business environments that are affecting this business. The expanding of Southern Light affects the community and businesses

Saving energy is an extremely efficient way conserve resources. Whenever there is a room in the facility that is not in use, turn off the lights. There are many methodical ways to conserve energy, but installing solar panels is one of the most useful ways, especially for a big corporation. Solar panels convert the radiation of the sun's rays into usable energy and are 100% eco friendly. They help diminish pollution immensely and will help assure a better future for humans, animals, and nature.

For new or retrofit construction, every choice can lead to energy savings; energy that is derived primarily from fossil fuels. The typical household LED replacement for a 60w light lasts about 50,000 hours. Pretending that an incandescent could also last that long, it would consume about 3,000 kilowatt-hours (kWh) of energy whereas the LE...
To understand how these lights can save money we need to look at the way they work. CFs consist of glass tubes whose inner walls are coated with a material that fluoresces when an electrical current is applied. Incandescent lights contain a filament that is heated by an electric current to the point that it glows; but the majority of energy put into the bulb produces heat, not light. The CF is more efficient at turning electrical energy into light than the incandescent bulb, and electricity costs money. Locally, Public Service charges around 6.1 cents per kilowatt‑ hour. Table I shows a comparison of three compact fluorescent bulbs with incandescent bulbs of similar light output, all made by the Philips Lighting Company. The life of the CFs is 10,000 hours, so this is the time period we will use.
LED shoes are all the craze these days, with people from all ages wanting to own a pair. And why not? After all, they're not only functional, but aesthetically pleasing as well. Most importantly, they make a fashionable option to a flashlight when walking at night. It is also best used with a hoverboard.
... concept is inadequate. The concept according to majority of retailers is just dressing a window, or just an unnecessary expenditure. The competitors’ today have an astonishing retail design stock and will have to compete purely on master merchandising and the technological edge.
According to Mr. Solar.com, “this type of energy production, known as the Photovoltaic Effect, is achieved by solar panels converting sunlight into energy. Solar panels are made up of several individual solar cells, composed of layers of silicon, phosphorous (which provides the negative charge), and boron (which provides the positive charge). Solar panels absorb the sunlight’s photons and by doing so initiate an electric current, producing electrons. The resulting energy generated from photons striking the surface of the solar panel allows electrons to be knocked out of their atomic orbits and released into an electric field generated by the solar cells, which then pull these free electrons into a DC or directional current.” This electricity then proceeds to a mechanical room beneath our house to a charge controller, which regulates the amount of energy sent to our 24V batteries to be stored.
Under cabinet LED lighting has become very popular in many homes. You can add LED lighting under your cabinetry by using LED pucks, strips, or bars. Adding lighting under your wall cabinets can help add light to specific kitchen areas where traditional lighting may not reach. It also can improve the overall ambiance of a kitchen. If you are not a fan of LED lighting, fluorescent and Xenon lights are great alternatives and can give your kitchen a unique look.
The photovoltaic effect, electricity can be created directly from sunlight. Some semi-conductor materials that are exposed to sunlight can create electron-hole pairs, which can be collected to produce electricity. This occurs when photons have energy above a certain threshold. These photons have shorter wavelengths. In silicon, the threshold for electron-hole production is in the infrared region of the electromagnetic spectrum.
Light bulb is one of the most influential inventions in the word. It makes us work more productive at night and helps us enjoy more activities at night. It significantly change people lives all over the world. The born of light bulb also helped us by making more inventions that related to light, such as phones, televisions, and computes. By using light bulb, we actually reduced the probability of having fire accidents because if we don’t have light bulb, we will use candles instead which can cause fire easily. There are a lot more benefits we get from light bulb, and all of these are credited to Thomas Alva Edison.
