Increase your yield rate: Why higher light intensity matters

Production efficiency can be easily measured by its yield rate, the proportion of defect-free products manufactured. To boost this figure, it is beneficial to employ modern LED curing lamps. These increase light intensity during production, which affects the photochemical reaction of polymers during light curing.

Higher light intensity offers several advantages:

• Higher light intensity leads to faster adhesive curing, resulting in reduced component dwell times in production facilities, thereby minimizing the risk of errors such as shifting or contamination.
• Higher light intensity ensures consistent energy distribution across adhesive surfaces, leading to homogeneous curing and eliminating areas that are not completely cured.
• Especially at shorter wavelengths, higher light intensity enables enhanced penetration of light into the adhesive, ensuring complete cure, even in thicker or translucent materials.
• Because of improved curing quality, the number of parts either requiring rework or that are rejected are reduced.
• Complete and optimal curing enhances the adhesive's bonding properties, increasing the number of products meeting quality standards.

As demonstrated, the use of modern curing lamps can lead to many production improvements. They are flexibly integrated, with the DELOLUX 20 series available in various configurations, including four lamp head sizes and light emission areas of 100 x 100 mm² or 202 x 49 mm². 

Integration into production lines is further facilitated with all DELOLUX lamps being plug-and-play compatible, easily arranged along or across production lines. This ensures homogeneous and reliable light curing without shading between lamp heads, even for large adhesive areas or long exposure paths.

Additionally, users benefit from a service life of 20,000 hours. 
Even at high light intensities, the reduced energy consumption of DELOLUX curing lamps helps promote significant cost savings.

For secure curing processes, it is recommended to regularly monitor lamp intensity with measurement devices such as DELOLUXcontrol.

Material incompatibilities

It is crucial to consider material incompatibilities, as certain materials could be damaged by specific UV wavelengths. The proper wavelength ensures that only the desired molecules in the adhesive react, without adversely affecting other components.

User-Friendly Operation

These actively air-cooled curing lamps are operated with the DELOLUX pilot A Series base unit. Up to four lamp heads can be connected and powered via the control unit, with users choosing between two variants:

• The first variant is designed solely for integration into PLC-controlled process systems, allowing no manual control outside the PLC.
• The second variant permits manual control via an intuitive touchscreen in addition to PLC control.

Various expansions are available depending on the number and light intensity of lamps to be controlled.

The use of the control device offers the following advantages:

• Multilingual control: For both automatic and manual processes.
• Precise monitoring: With devices such as DELOLUXcontrol.
• User-friendliness: Password-protected user management ensures secure access.

Conclusion

DELOLUX light-curing solutions are more than just lighting. They are an integral part of modern, efficient production processes. Combining high light intensity, energy efficiency, and durable design, they reduce curing times and improve production quality, leading to increased yield rates and significant cost savings.

Thanks to their versatility and ease of integration into existing production lines, DELOLUX lamps sustainably optimize industrial bonding processes. With customizable wavelengths, the lamps suit diverse curing needs and reduce the risk of material incompatibilities.
