A portable dental unit or delivery system is a portable, mobile unit that can become a complete, fully-functional dental office in a matter of seconds. These units help dentists practice at locations that do not have the required facilities like clean water or compressed air.
These units come with self-contained water, compressed air and vacuum systems so that the need for on-site plumbing is completely eliminated. The possibility of infections is also minimized with the use of clean water from the system. The units come with a clean water bottle and a drain water bottle. A sizeable air tank provides air for the various dental procedures. All the dental instruments are contained within a carry case that has wheels, making the whole unit extremely portable.
Some of the dental instruments found in the dental delivery system would include an ultrasonic scaler, a 3-way syringe, a saliva ejector, a 2 or 4 hole hand piece, a LED curing light, a compressor head with sufficient power, a fiber optic handpiece, an on/off foot switch, a mobile patient chair, a mobile dentist stool and an operating light.
Traveling dentists and health care personnel can use these systems at any location very effectively for a wide variety of dental procedures. The units can also be used in nursing homes and private care homes.
Apart from their use in medical facilities, these portable dental units can also be used effectively in various other locations which are far removed from proper health care facilities. Missionaries working in remote mission fields in third world countries often minister to the needs of locals that need medical attention. These portable dental units can be extremely useful in such areas for qualified health care personnel to provide medical relief to patients.
The battle field is another area in which dental delivery systems can be of tremendous use. Soldiers injured in battle can be immediately attended to using a portable unit that has the required instruments for basic medical aid.
Sometimes, vacationers in camping sites and wilderness regions might also need medical assistance during emergencies. Dental delivery systems can be of tremendous use in such circumstances.
Therefore, these portable dental units not only help dentists attend to patients within the confines of a medical facility, but also in remote regions far removed from medical care, and sometimes from civilization itself. The importance of these units can never be overemphasized as they are of vital importance in the medical field for a wide variety of medical procedures.
The new Audi A6 intends to challenge a lot of technology found in its competitor models, one of these innovations is the new all LED headlights. The A6 will be the first executive saloon in the market to have all LED headlights, an optional extra in exchange for the more familiar halogen or bi-xenon lamps that come as standard.
The Audi A6s advanced LED headlight units emit a strong white light that is similar to daylight, and use just 40 watts of electricity each, making them yet another important weapon in the battle against energy consumption. The advanced LED units use just four one-chip and five two-chip LEDs to create dipped-beam light, and 24 white LEDs to make up the daytime running lights in each headlight. This keeps power consumption and maintenance down, and gives excellent life span.
All LED headlights are not new in the Audi line-up, the Audi R8 was the first ever production car to feature all-LED headlights and now are becoming common across the Audi range. The advanced all LED headlights will also be available on the new A7 Sportback and Audi A8 luxury saloon.
The all LED headlights are further enhanced by intelligent systems such as adaptive light control and high-beam assist, which give maximum visibility without dazzling other road users. Simply put the adaptive light system adapts the light provided by the headlights to the driving conditions, with different arrangements of light when driving in the city, country roads and on motorways.
The Audi high-beam assistant automatically varies the range and width of the headlight beam between dipped and full according to the road conditions. The system also incorporates an all-weather function that uses the rear view mirror camera to detect the lights of on-coming traffic and adjust the headlight intensity to give optimum visibility in varying conditions without disturbing other road users.
The Audi A6 is now available to order from Audi Bury St Edmunds, prices start from 30,145 for the 2.0 litre TDI model. The all LED headlight upgrade costs an additional 2,710.

Technology led by care – care for the environment – that is the first identity of the LED light bulb. LED or Light Emitting Diode bulbs are solid-state lamps that have semiconductor light emitting diodes (LEDs), organic LEDs, or polymer LEDs. Although the light emitted by one diode is insufficient for domestic or commercial use, multiple diodes put in together normally do the trick pretty well. A single high-power chip emits about 7500 lumens by using a mere 100 watts of power.
Why Use LED Light Bulbs
Notwithstanding the energy efficiency of LED light bulbs, their technology is useful in many more ways. They are mercury-free, which makes them all the more environment-friendly and pro-health. LED bulbs also have an enhanced life of 50 to 100 thousand hours! Their longer life renders them pocket-friendly and cost-effective. LED light bulbs are friendly to more than just your pocket. The simple fact that they do not produce considerable amount of heat during use makes the environment smile in gratitude as well. LEDs convert an amazing 90 percent of the electric energy into light as against a mere 15 percent converted by normal halogen light bulbs.
LED light bulbs are also shock-resistant to a great degree. They can withstand frequent switching on and off better than the normal incandescent and halogen lights. They also weather better in areas of climatic extremes.
Artistically speaking, the LED light bulbs produce light in vibrant colors, which, if used aesthetically, can enhance your interiors as never before.
LED Bulbs: Types
Whether you are a homemaker, an executive, hotelier, or surgeon, there is an LED light bulb for you. There are LED bulbs with different Kelvin ranges for different color temperatures. There are LED bulbs with focus beams of different degrees. The most popular and commercially used LED light bulbs are the GU10 LED bulbs.
The GU10 LED light bulb is so named due to the type of fastening it uses, that is, the standard bayonet mount, acceptable in most Commonwealth nations. GU10 Led bulbs are very popular with businesses that require sharp, crisp, and, of course, cost-effective lighting. Showrooms, offices, shopping stores are a few places that utilize the GU10 bulbs to suit not only their electricity bills, but also the saleability of their stock due to effective lighting.
Add to the enhanced lighting, the additional benefits of the GU10 bulbs like the option of dimmed light, shades of white light, and bulbs designed for several commercial and domestic purposes, make these bulbs highly desirable and efficient. As pure as its color is, the GU10 light bulb is also easy to use and easy to replace when it needs (rarely) replacement.
LED light bulb, especially the GU10 bulb, is a boon to home and office lighting. Not only do they bring your electricity bill right down, they also add that aesthetic appeal to your otherwise drab settings. The LED technology is the result of arduous years spent with the sole motive of reducing the world’s carbon footprint.
LED light bulb technology is the groundbreaking technology in the world of domestic and commercial lighting. GU10 light bulbs are the radical LED bulbs that have enhanced lighting features besides being very cost-effective.
Light-emitting diodes (LEDs) were an accidental discovery at first. At the beginning of the 20th century, it was discovered that when electricity was applied to the semiconductor Silicon Carbide (SiC) it produced a light. This light was too dim to be of any use so the research was never distributed. This could have been the end for the LED, but it wasnt content to die out.
Nearly 20 years later Russian and German scientists revisited the idea of light produced this way. The light was still of such poor luminance that the idea nearly died again. A report published in 1936, which helped to invent the term electroluminescence, revived the research for light from this source. The science of electroluminescence languished in obscurity for a while. It began to gain favor again in the 1950s when some British scientists started experimenting with it again. This led to the first infrared LED. From this technology came the first visible spectrum LED, in red, from Gallium Phosphide (GaP).
This was the start of the LED revolution. From that point each decade brought advances in the technology of light-emitting diodes. The use of different substrates brought brighter lights of different colors. The colors advanced from red to orange and on to pale green, then yellow and on to a brighter green. By the 1990s the use of Gallium Nitride helped usher in the era of blue LEDs. These blue lights became the basis for white light. The use of fluorescent phosphors helped change that blue light into high intensity white lights. Now LEDs can be found in almost every visible color of light.
This technology has led to additional uses for the LED as well. Due to their low light output they started out in indicator lights and display light applications only. The cost of materials was an issue at first and, therefore, they were used only in expensive laboratory and test equipment. They later began to be used in appliances, calculators and watches. The advent of additional colors increased their use in displays. They could be used in signs and digital display equipment.
The first LED flat panel television prototype was produced in 1977, by James P. Mitchell. This prototype was a red, monochromatic display. Later, in the 1990s, low-cost, efficient blue LEDs emerged moving this use along. Once a full spectrum of colors was realized in the late 1990s the flat panel LED television became a fully functional and popular option.
As the LED technology advanced and the luminescence increased, the uses for LEDs increased. LEDs began popping up in devices used to illuminate areas. Flashlights, landscape lighting, and other lighting sources became popular. Emergency lights began to use this technology. Traffic lights were replaced with LEDs. Interior lighting and headlights in vehicles became a common home for these lights, as well. As the cost of producing the lights decreased, and the availability of colors and brightness increased, the uses exploded.
From an accidental discovery to a common household name, the history of LEDs is a long one. The early discovery and limited uses of the light-emitting diode did not show much promise. Very few early researchers would probably have predicted the many, varied uses for this technology. The LED certainly earned its prominent spot in todays society.
