Osram Vitalux 300 Watt

The ULTRA-VITALUX lamp produces a mix of radiation very similar to that of natural sunlight and can have the same positive
effects on the body as the sun. This blend of radiation is generated by a quartz discharge tube and a tungsten filament.
The bulb is made of special glass which allows only the part of the output that is contained in natural sunlight to pass through.

Because of their sun-like radiation properties, ULTRAVITALUX lamps are used in industrial material testing, particularly for
testing materials and equipment in different environments to DIN 50 010:

• Suitability for use in the tropics
• Artificial ageing
• Weathering
• Changes in material properties, reliability or service life under particular climatic conditions, etc.

The total irradiance of the sun on the surface of the Earth at noon on a sunny June day is around 1 kW/m2 (annual average solar
radiation at a latitude of 50° N is 200 W/m2). An array of 16 lamps per square metre at a distance of about 50 cm between the bulb
crown and the irradiated object achieves a similar uniform irradiance.

ULTRA-VITALUX lamps are used for curing plastics. Modern plastics are cured by exposure to UV radiation. Special photo
initiators cause polymerisation in plastics when the plastics are exposed to UV radiation.

The advantages of the process are:

• Only one substance is needed. There is no need for mixing and dosing
• Under normal indoor lighting, processing times can be almost any length
• Pot times are no problem
• Rapid curing with UV radiation
• Clean processing in industry, workshops and DIY

ULTRA-VITALUX lamps are suitable for the exposure of photo-resists. In electronics the pattern of printed circuits is transferred by
means of UV exposure onto a photo-resistive layer. After development, the board can be etched, leaving only the conductor paths.

The advantages of the process are:

• Simple handling
• High UV content
