Special emitters for optimal energy efficiency

Heraeus special emitters promote both: energy production and energy saving as the examples below show. It is therefore worthwhile to examine industrial processes in detail to make them more energy efficient, and thus more cost effective, by using productive light.

IR emitters

Infrared emitters consume energy. However, in many cases they do this so efficiently that, all in all, energy is saved in many industrial manufacturing steps. Infrared emitters adjust precisely to the product and the process. Energy precisely at the wavelength that is best converted into heat by the respective material. Heat generation without contact, with high power and within seconds.

UV lamps

UV lamps are used in various applications, e.g. the preparation of water or air, the treatment of surfaces or curing processes. Specialty UV light sources attuned to the industrial process help save energy. For instance, the shape of the lamp may be adapted to the object being irradiated to minimise scattering loss of the UV light. So the UV light arrives precisely where it is needed and energy consumption is reduced.


The share of LEDs is also growing in the field of specialty light sources. For example, UV LEDs are increasingly used in industrial curing processes due to their low power consumption and long service life. Moreover, as UV LEDs can be switched on and off without delay, they use energy very efficiently.

Arc and Flash lamps

Xenon flash lamps help test solar cells to characterise them and assign them to power classes. This requires reliable and reproducible light sources which have a spectrum that comes as close to that of the sun as possible. Xenon flash lamps meet these requirements. Small and ring-shaped or linear and up to two metres long. For example, they ensure realistic testing of efficiency and in this way optimise solar energy production.
