News Arc + Flash lamps

The Arc and Flash division of Heraeus Noblelight will present a poster at Subtherm in Dresden, from 25 to 27 October 2011.

The Subtherm is an international Topical Workshop on subsecond thermal processing of advanced materials.

Our poster will show features and advantages of Heraeus special lamps for rapid thermal processing.

At EU PVSEC in September in Hamburg Heraeus Noblelight presents Specialty lighting products for photovoltaics.

Specialty emitters from UV to infrared make solar cells more efficient

Solar cells and modules have to be tested to check production quality, characterize the cells, and assign them to performance categories. Only perfectly matched cells are ultimately combined into one module, which requires reliable and reproducible light sources that mimic the full spectrum of the sun’s light rays as closely as possible. Xenon flash lamps—from small and circular to linear and up to two meters long—accomplish this.

Infrared emitters are part of a project sponsored by the German Federal Ministry of Education and Research. Four partners are working on system designs with the aim of researching a new manufacturing process for CIGS semiconductor layers that will attain the highest levels of module efficiency. The partner for heating technology is Heraeus Noblelight, which has decades of experience in infrared heating technology. Typically, the manufacture of solar cells uses QRC infrared emitters with nano reflectors, which perform their tasks in a vacuum or under high-temperature conditions in a particularly stable and energy efficient manner.

Xenon lamps emit a versatile broadband spectrum, with useable wavelengths from 160 – 1000nm. Altering the pulse shape, duration or current density can maximise output for your desired wavelength range, and achieve optimal application results.

UV wavelengths can be filtered or enhanced with different quartz envelope materials. The noble gas Xenon produces the required spectrum without harmful additives, such as mercury and metal halides, making it an eco-friendly solution.

Flash lamps can deliver effective energy density in very short pulse durations from 10’s of micro seconds, with instant on/off capability, resulting in rapid response processing.

Heraeus Noblelight Arc & Flash division combines experienced application engineers, lamp design expertise and high technology manufacturing techniques, developing our customer’s ideas into applications solutions.

The development of Heraeus Ignite Technology HIT^TM 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.

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

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.

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.

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

Furthermore the ignition process is more reliable and more constant. This is very important, where power supply and system may be limited.
