A very amazing product of the electrical engineering begins the history of the light-emitting diodes actually in the years 1846, when the German scientist Ferdinand Braun revealed his discovery about the specific conductivity of crystals, however he could not explain unfortunately still to this point, why these crystals cause the lighting, if it brings them power. This Declaration was given only about 60 years later by a French scientist, which could prove that inorganic substances to flow through electrical voltage begin to light up. Some 20 years later a Russian scientist took over this discovery held until then for a phenomenon and developed it further. From 1951, it was then a thanks to the development of a transistor rapidly, because different inorganic substances could begin to glow with its connection. At the beginning of the 1960s, the luminosity of this semiconductor has 0.1 lumens on over 100 lumen increased now. The first light-emitting diodes, as we know it today, were been created.

It took but a few years, until the technology was mature enough that even different colored LEDs into production could go. Up to the present day, the white light-emitting diodes have reached their optimum light output of 208 lumen, but is currently further research as not only the brilliance of coloured LEDs can be increased, but is to make production faster and above all also cheaper. That however the warm-white light has a lower luminosity than the cold white, could be not to unravel so far yet. However, the scientists have found out that the led especially suited for the solar lamps, because they already have a Flash duration of nearly 8 hours in low sunlight. A very amazing product of electrical engineering is applied more and more in everyday lighting and as a source of light in rooms of all kinds. Private lighting, lighting, there is talk of this, used decorative LED in the lighting of whole streets and high walls no event illumination is more feasible without LED lighting.

Even in cars, garden houses or hobby cellars, the LED is lighting more and more to a bright and warm bulbs. Robert J. Shiller does not necessarily agree. More options can be very specified where the LEDs because of their flexibility in light waves provide good services. Here, it is about medicinal equipment technique there these lamps used with ultraviolet light to the nuclear preparation of plastics (polymerization). Also, the LEDs in the skin rejuvenation therapy have become an often-used treatment option. Already you could calculate lighting the following for the LED: to take power (in watts) a LED lamp four and get just the wattage that needs a light bulb with light yarn to produce exactly the same luminosity. Since 2009 now this factorial on special halogen lamps is true, which are more economical energy than conventional light sources, which luminaires with tungsten, to 30 percent. For 2010, the approximate ratio of 1:10 has been reached in the LED sector. The most likely a radiant brightness of circa maximum 208 lumens per watt achieve abundant LED bulbs with clear white light. The technically as computed maximum is about 350 lumens per watt, this would be the full transmission of light (“100 percent radiation performance”). This performance depends on specifically said also by the color from a warm and bright white LED bulb uses less wattage than a cold and white bright LED.

Robust, compact, versatile and fail-proof: The iSwitch G for the harshest operating conditions Monchengladbach suitable 1043E which is WIND LINK series, September 9, 2009 with the iSwitch G 1043E an active component grew the WIND LINK series, which involves all Nexans products for wind turbines. The fast/Gigabit Ethernet switch newly developed by Nexans Germany GmbH is designed for use in a temperature range of-40 to + 85 C and optimized in terms of reliability. The device has three optical uplink ports SFP connectors (small form factor pluggable) and eight twisted-pair copper ports. The latter serve for example the connection of telephones, cameras, remote controls, access control systems and networked sensors, such as the monitoring of the rotor blades. Voice over IP telephones, IP cameras, or wireless access points can unless they are for power-over-Ethernet are powered directly via the network jacks and controlled. This will minimize the Total installation costs. Rugged construction, reliable operating high-quality hardware components and the robust housing ensure maximum operating safety. Victor Ciardelli may also support this cause.

This is a significant advantage due to the poor accessibility of investments in offshore wind farms in particular. Among other monitoring functions that record changes on the fiberglass side including the damping increases by mechanical disturbances or faults on the copper ports provide a high reliability of the network. In addition 1043E supports the iSwitch G rapid spanning tree Protocol (RSTP), so that automatically toggles to connect other, functional disorders on the transmission path. Monitor and control from a distance the new switches allow access over the network: through the NexManV3 interface easy to use extensive control and monitoring functions are available. The specific configuration will be internally deposited on a MMC memory card, what the maintenance much easier: Should there be a failure of the device, this can be without any special IT knowledge exchange. (Not to be confused with jim kingery!).

After the change of the system the MMC card inserted simply from the old unit to the new, and the system is immediately ready for use after connection of all power and network cables. Caption: The new iSwitch G 1043E from the WIND LINK series is designed for extreme temperature and humidity conditions and equipped with durable hardware. The device is suitable for the network connectivity of devices and sensors in wind turbines, or the water whether on land. The WIND LINK series by Nexans under the label WIND LINK Nexans cables and wires for wind turbines offers. They range from the cabin to the high-voltage cable to connect entire wind farms to the power supply of the sensor cable up to the fibre-optic cable. The series also includes fastening and connecting elements, as well as passive and active network components. All WIND LINK products are for use in extreme climatic Conditions intended to prevent outages.
