Heraeus Ignite Technology for reliable lamps

20.09.2010
  • Arc and Flash lamps must ignite reliable
  • A new manufacturing process helps to significantly reduce the Ignition voltage
Arc and Flash lamps are used for a variety of different applications. For precise measure of distance in laser based range finders, for laser excitation in industry also for aesthetic and sun simulation applications. These lamps must work reliably and the ignition process should be constant and repeatable.

The development of Heraeus Ignite Technology (HIT™) embodies Arc and Flash lamps of Heraeus Noblelight, which have a trigger spot. Through a new specific developed manufacturing step the electrode material will be vacuum metalized in a certain form and on a fixed place in the lamp. This reduces the Ignition voltage and makes the Ignition process more reliable.

Tests show a reduction of the trigger voltage of more than 60% and an increase in the efficiency of an existing system.

Hair removal and skin treatment with pulsed light are a growth market. Flash lamps, which are the main light source of pulse light devices, must have an outstanding quality so that a safe and effective treatment is possible.

The ignition properties of Arc and Flash lamps can be inconsistent, because the activation process is very complex and demands a priming or a start ionisation in the lamp gas (e.g. Xenon or Krypton).

It has been shown in prior art that by sputtering part of the electrode material on to the surface of the quartz near to the electrode, the voltage to ignite a lamp can be significantly lowered. The negative aspects of the prior art are that there can be a reduction in lifetime due to excessive sputtered material both artificially aging electrodes and blocking light transmission from the plasma.

Heraeus Ignite Technology HIT™

Heraeus Noblelight Ltd, Cambridge, developed a process to sputter some of the electrode material to improve the Ignition process without affecting lamp lifetime.

Through laser processing a defined amount and shape of evaporated material is created on the quartz inner surface. This has minimal effect on the optical properties of the quartz material and thereby lamp lifetime is not compromised.

The process significantly reduces the ignition voltage; initial results show an average trigger voltage reduction of more than 60%.

Furthermore the ignition process is more reliable and more constant. This is very important, where power supply and system may be limited. It may be possible to utilize a more powerful lamp to be used without replacing the pulse generator, allowing the operator to use his available equipment and potentially increase his efficiency clear.

Heraeus Noblelight Ltd. in Cambridge develops and produces continuous arc and Flash lamps. Xenon/Krypton specialty lighting sources are successfully used in many laser and non-laser applications such as drilling, welding, cutting, marking, engraving, medical and aesthetic applications as well as sun-simulation.

All lamps are 100% tested to ensure expensive down time is avoided.

Heraeus, the precious metals and technology group headquartered in Hanau, Germany, is a global, private company with over 155 years of tradition. Our businesses include precious metals, sensors, biomaterials and medical products, dental products, quartz glass, and specialty light sources. With product revenues of € 2.6 billion and precious metal trading revenues of € 13.6 billion, as well as more than 12,300 employees in over 110 subsidiaries worldwide, Heraeus holds a leading position in its global markets.

Heraeus Noblelight GmbH with its headquarters in Hanau and with subsidiaries in the USA, Great Britain, France, China, Australia and Puerto Rico, is one of the technology and market leaders in the production of specialty light sources. In 2009, Heraeus Noblelight had an annual turnover of 71.6 Million € and employed 707 people worldwide. The organisation develops, manufactures and markets infrared and ultraviolet emitters for applications in industrial manufacture, environmental protection, medicine and cosmetics, research, development and analytical laboratories.

Im Focus: Nanoparticles help with malaria diagnosis – new rapid test in development

The WHO reports an estimated 429,000 malaria deaths each year. The disease mostly affects tropical and subtropical regions and in particular the African continent. The Fraunhofer Institute for Silicate Research ISC teamed up with the Fraunhofer Institute for Molecular Biology and Applied Ecology IME and the Institute of Tropical Medicine at the University of Tübingen for a new test method to detect malaria parasites in blood. The idea of the research project “NanoFRET” is to develop a highly sensitive and reliable rapid diagnostic test so that patient treatment can begin as early as possible.

Malaria is caused by parasites transmitted by mosquito bite. The most dangerous form of malaria is malaria tropica. Left untreated, it is fatal in most cases....

Im Focus: A “cosmic snake” reveals the structure of remote galaxies

The formation of stars in distant galaxies is still largely unexplored. For the first time, astron-omers at the University of Geneva have now been able to closely observe a star system six billion light-years away. In doing so, they are confirming earlier simulations made by the University of Zurich. One special effect is made possible by the multiple reflections of images that run through the cosmos like a snake.

Today, astronomers have a pretty accurate idea of how stars were formed in the recent cosmic past. But do these laws also apply to older galaxies? For around a...

Im Focus: Visual intelligence is not the same as IQ

Just because someone is smart and well-motivated doesn't mean he or she can learn the visual skills needed to excel at tasks like matching fingerprints, interpreting medical X-rays, keeping track of aircraft on radar displays or forensic face matching.

That is the implication of a new study which shows for the first time that there is a broad range of differences in people's visual ability and that these...

Im Focus: Novel Nano-CT device creates high-resolution 3D-X-rays of tiny velvet worm legs

Computer Tomography (CT) is a standard procedure in hospitals, but so far, the technology has not been suitable for imaging extremely small objects. In PNAS, a team from the Technical University of Munich (TUM) describes a Nano-CT device that creates three-dimensional x-ray images at resolutions up to 100 nanometers. The first test application: Together with colleagues from the University of Kassel and Helmholtz-Zentrum Geesthacht the researchers analyzed the locomotory system of a velvet worm.

During a CT analysis, the object under investigation is x-rayed and a detector measures the respective amount of radiation absorbed from various angles....
