OSRAM IRC ENERGY SAVER Halogen lamps achieve energy savings of up to 30%. This is made possible by two different technical principles:
A reduction in losses due to thermal radiation (IRC): Special bulb geometry and a sophisticated coating on the bulb ensure that the thermal (infrared) radiation is reflected and the heat emitted from the filament is reflected back to the filament. As a result the filament is heated further. This means that less electrical energy has to be supplied to the filament. This technology is used for all low-voltage Energy Saver lamps (12 V) because of the optimum geometric conditions.
A reduction in the thermal losses via the filler gas (xenon):
As the size (mass and diameter) of the gas atoms increases, the thermal conductivity of the filler gas decreases. By using the appropriate lamp filler gas, the heat loss of the tungsten filament via the gas can be reduced. This means that less electrical energy is needed to heat the filament. In addition, the use of a filler gas with atoms as heavy as possible slows down the vaporization of the tungsten atoms from the filament. This prolongs the life of the lamps. Xenon is an extremely rare gas (making up only 0.0000087% of the atmosphere, or 0.087 ppm). Of all the inert gases, xenon best meets these requirements. Despite the high cost we therefore use xenon as the filler gas in al the OSRAM Energy Saver lamps.
Other effects:
If we also take into account the lower costs for air conditioning and the lower relamping costs thanks to the longer lives of the IRC Energy Saver halogen lamps, the cost savings compared with standard lamps may be as high as 65% (depending on electricity costs).
Benefits of IRC Energy Saver halogen technology:
* Up to 65% cost savings
* More than double the average life of standard halogen lamps
* The luminous intensity and color perception remain constant throughout the life of the lamp
* Higher luminous efficacy
* Lower thermal output
* Lower power consumption
