Technology has influenced our lifestyle by changing the vision of industrial development in sales and market behavior. Online shopping has become a most important medium between manufacturers and consumers in the market. The rapidly growing online shopping has several advantages. One of the most notable facts is that, online shopping is less time consuming than visiting a physical market or a shopping mall. Apart from that, you can expect huge numbers of varied collections to choose the right product that you’re looking for, and also you can compare the prices of the products at online shopping. Thus, online shopping is not only time saving, but it also saves a lot of your money and energy.

Lighting change towards the betterment
Light has become one of the basic requirements in the lives of the human. After the invention of lights in 1847 by inventor and businessman, Thomas Alva Edison, it has been transformed and taken to the different level, many a times. In the very beginning it was an electric bulb which people started using for the purpose of having light in the dark nights when the sun goes down. Slowly with the advancement in the technology, lights were then became aid in performing daily chores and reading.
Gradually with the increased use and development in technology, lighting has now become a part of our lives. Many Italian and German brands such as Foscarini, Kreon, Artemide and more are some of the renowned names in the advanced lighting system. Kreon lighting is one of those advanced lights. Foscarini and Artemide have consistently come up with the creative ideas in terms of designs, efficiency and material used in lighting. Similarly kreon dolma is one such product from the brand Kreon. It is available for exteriors and interiors of the place.
Many brands also manufacture lighting system using fiber optics in order to support the concept of energy conservation which has become a need-of-hour today. These brands provides different variety and range of lights; decorative lighting, smooth lighting, high intensity lighting, security lighting and display lighting which is still counting.
Kreon dolma is made up of aluminum that can be used with concrete, wood or metal meaning it can be placed almost everywhere in the premises. The two different widths support better and proportionate illumination. Along with Foscarini, Artemide and other lighting brands, Kreon lighting is growing towards the better phase of the lighting system which is luxurious and efficient.
Today we cannot survive without saving resources and energy. Thus many lighting manufacturers have come up with the idea that can restore or transfer the light from largest and the most efficient source, the Sun. They are trying to use solar energy in producing artificial lights. Solar lighting system is the recent concept of lighting on which most of these brands are working. Until any new innovation in the world of lighting, let us enjoy and experience the present designs and forms of lighting using them wisely.

Led lighting : long service life & high energy efficiency
An led light bulb is a solid-state lamp that uses light-emitting diodes (leds) as the source of light. led lamps offer long service life and high energy efficiency but initial costs are higher than those of fluorescent and incandescent lamps. Chemical decomposition of led chips reduces luminous flux over life cycle as with conventional lamps.
The leds involved may be conventional semi-conductor light-emitting diodes, organic leds or polymer light-emitting diodes devices.
An assortment of led light bulbs commercially available as of 2010 as replacements for screw-in bulbs including floodlight fixtures(left), reading light (center), household lamps (center right and bottom) and low-power accent light (right) applications.
Led lightings are made to replace screw-in incandescent light bulbs. An energy-efficient bulb that claims to be the equivalent of a 60W tungsten bulb must have a minimum light output of 806 lumens. led lights are mercury-free, unlike fluorescent lamps. The higher purchase cost than other types may be more than offset by savings in energy and maintenance.
Several companies offer led lamps for general lighting purposes. The technology is improving rapidly and new energy-efficient consumer led lamps are available for wall lighting.
A light-emitting diode (led) is a semi-conductor light source. leds are used as indicator lamps in many devices and are increasingly used for other lighting. Appearing as practical electronic components in 1962, early leds emitted low-intensity red light but modern versions are available across the visible, ultraviolet and infrared wavelengths with very high brightness.
Light-emitting diodes are used in applications as diverse as aviation lighting, automotive lighting, advertising, general lighting and traffic signals. leds have allowed new text, video displays and sensors to be developed while their high switching rates are also useful in advanced communications technology. Infrared leds are also used in remote control units of many commercial products including televisions, DVD players and other domestic appliances.
With the development of high-efficiency and high-power leds, it has become possible to use leds in lighting and illumination. Replacement light bulbs have been made as well as dedicated fixtures and led lamp. leds are small, durable and need little power, so they are used in hand held devices such as flashlights, led strobe lights or camera flashes operate at a safe, low voltage, instead of 250+ volts found in xenon flash lamp based lighting.
led light bulbs could be a cost-effective option for lighting a home or office space because of their very long lifetimes.
Parts of an led
The led consists of a chip of semiconducting material doped with impurities to create a p-n junction. As in other diodes, current flows from the p-side or anode to the n-side or cathode but not in the reverse direction. Charge-carriers—electrons and holes—flow into the junction from electrodes with different voltages. When an electron meets a hole, it falls into a lower energy level and releases energy in the form of a photon.
Most materials used for led production have very high refractive indices. This means that much light will be reflected back into the material at the material-air surface interface. Thus, light extraction in leds is an important aspect of led production.
