SUPRATEC
 
This high performance halogen metal vapour lamp was developed specifically for industrial applications. A particular combination of metal halides generates strong radiation in the UVB range (280-315 nm) and especially in the UVA range (315-380 nm). The quartz bulb absorbs UV radiation below 250 nm. This means that no ozone is generated.
 
Applications

• Large-scale hardening of plastic parts, e.g. deep drawn components or plastic veneers
• Hardening of lacquers and paints
• Exposure of diazo film material and print layouts
• Modern adhesive technology
• Artificial material ageing

The spectral radiation profile of the lamp corresponds almost exactly with the reaction profile of photo-sensitive plastics. This offers the plastics industry a powerful, emission free, and ecologically benign hardening method.
 
Advantages

• Labour and time consuming task of mixing different substances becomes obsolete
• No restriction on handling times prior to irradiation
• Irradiation causes immediate hardening; increasing productivity
• No material loss through premature hardening
• Simplified production processes
• Low energy consumption

Other applications of the powerful UV sources include exposure of film material and printing plates in the printing industry, as well as artificial weathering and ageing of materials in test laboratories.
 
Intensive UV radiation has significant advantages for material tests using fluorescent excitation. SUPRATEC lamps are particularly well suited for integration into production processes and mass production. The standard range comprises 150 W, 400 W, 500 W, 600 W, 800 W, 1000 W and 2000 W lamps.
 
 
DULUX Blue
 
DULUX Blue compact lamps are low pressure mercury discharge lamps. An electric field between electrodes stimulates the emission of energy intensive UV radiation from mercury vapour in a glass tube. A fluorescent material on the inside of the glass converts this UV radiation into light with the desired spectrum.
 
The difference between DULUX Blue compact low pressure lamps in special light colours and conventional compact fluorescent lamps lies in the application of special fluorescent materials. The energy intensive UV radiation is effectively converted into blue radiation or into long wave UV radiation.
 
 

DULUX Blue (colour of light 71)
 
This lamp emits light in the visible, blue spectral range of 400-550 nm. Because there are no health risks associated with this lamp, even during professional use over a whole day, and due to its ease of operation, it is an ideal tool for the polymerisation of blue-sensitive plastics, adhesives, lacquers and paints, even for layer thicknesses of more than 1 mm.
 
Example applications for DULUX Blue are torches or mobile plastic hardening equipment for car or boat repairs.
 
 
DULUX Blue UVA (colour of light 78)
 
This lamp very effectively emits long wave UVA radiation in the range 350-400 nm. The spectral radiation profile is close to the reaction profile of photo-sensitive plastics. DULUX Blue UVA is therefore particularly well suited for hardening modern plastics, adhesives and lacquers - emission-free and environment-friendly.
 
It is a simple, compact and user friendly solution with low energy consumption.
 
In addition to its application for the polymerisation of plastics, the convincing properties of the DULUX Blue UVA lamp also make it applicable in other modern technology areas. It has, for example, become a common tool for stimulating fluorescence in scientific investigations or as a source of UV light in the production of circuit boards.
 
The stimulation of fluorescence is also used to recognise bank note and credit card forgeries. Here, black glass filters are applied for increased contrast (for example MUG 2 from DESAG-Schott).
 
Further Applications Light Colour 71 and 78:

• dissociation of bilirubin
• hardening of plastic dental fillings
• surface sealing in the production of dental spares
• cosmetic nail shaping
• insects pitfalls

ULTRAVITALUX
 
The light from this special lamp is similar in its composition to the complete radiation mixture of natural alpine sunlight. It is generated by a tungsten filament and a high pressure lamp. The special glass bulb of the ULTRAVITALUX lamp is fitted with an internal reflector which focuses the radiation. Special doping of the glass ensures that the lamp only emits the UVA and UVB radiation contained in sunlight.
 
A significant advantage of this lamp is its easy handling. It has an E 27 base which allows it to be used without additional equipment wherever there is a 230V mains voltage supply.
 
Due to its sun-like radiation spectrum, the ULTRAVITALUX lamp is particularly well suited to simulating the sun in industrial material testing. In many production fields, this testing of materials and equipment is an important part of quality assurance.
 
In many fields of production, testing of materials and equipment is important for ensuring high quality standards. Laboratory tests can provide valuable quick-motion insights in the following areas: fitness for service in the tropics, artificial ageing and weathering, determination of changes in material properties, or functionality and durability under unusual climatic conditions.
 
The total irradiation of natural sunlight on the earth's surface with the sun in zenith position is approximately 1 kW/m². This average is achieved by evenly arranging 16 lamps per square metre of the area to be treated (distance between bulb and material to be irradiated about 50 cm). The yearly average of solar irradiation at a latitude of 50� North is about 200 W/m².
 
The high proportion of UV radiation in the spectrum of this lamp also makes it a useful accessory for hardening plastics (polymerisation). The application of UV lamps has greatly simplified the handling of plastics and adhesives.
 
Dosing and mixing of different components, and working under time pressure due to limited pot life are largely a thing of the past. Under normal room illumination the plastic material can be handled and processed for almost any length of time. It can then quickly be hardened under UV irradiation.
 
Because of its advantages - simple handling and low costs - ULTRAVITALUX is now used extensively for this application in workshops, in mobile equipment for repair work and for hobby activities.
 
ULTRAVITALUX has also found entry into the electronics industry. Because of its high UV yield and its simple handling, the lamp is frequently used for exposing UV-sensitive photo-resist in the production of circuit boards.
