Industrial LED Solutions

In addition to Direct Laser Writers and customized solutions, ‘Industrial LED Solutions’ form the third pillar of the 4PICO range. We develop and deliver LED-based equipment for specific tasks in high-tech manufacturing processes.This concerns the UV curing of adhesives, paints and coatings as well illumination for production inspection. We are particularly strong in providing tailor-made solutions, fitted exactly to all relevant parameters of your production process.

Custom made solutions in LED’s

While developing a custom made LED application our starting point is always the actual process and requirements of the customer. Based on the requirements and our expertise we design, test and build electronics, optics and housing. Interested in such a customized approach? Please contact us.

Curing with LED’s

4PICO has extensive experience in the use of LEDs as an alternative to mercury lamps for curing adhesives, paint and coatings. We use high power UV LED's ranging from 365 to 420[nm]. Matching LED wave lengths with paint, adhesive or coating properties is key to the succes of illumination! We can illuminate material with an intensity of 8 Watts / cm2 and in almost unlimited dimensions. For example, we have already supplied lighting strips that were over 3 meters long. Depending on the application we design with passive cooling or active cooling with air or liquids.

Inspection with LED's

When inspecting a production process, demands are put on contrast, intensity and lifetime. With our custom made LED inspection solutions these demands are met. We can apply different colour types (including white) in order to achieve a range of contrast conditions. If extreme intensity is required we apply special lenses which allows us to reach an intensity of 1.000.000 lux. Cooling is an integral part of the design, to avoid intensity drop and lifetime reduction.

Realised Projects

Curing of adhesive

For the pre-production of LCD screens we designed needed equipment to cure the adhesive in a few seconds. We delivered LED curing solutions in different dimensions up to 1200x1900mm with 2500 LEDS (total power consumption of 7.5 KWatts).

Curing of replication lacquer

Added by us to the production line which manufactures lenses for mobile phones: a LED-station to cure replication lacquer. In this application 8'' wafers wafers are cured with a specific wavelength and intensity. Our solution with LED illumination offers many advantages compared with a mercury light: lower cost, lower power consumption, homogeneous illumination and complete control of the illumination intensity.

Portable curing light

For experimental applications 4PICO delivers a portable curing station (1.5 kg). This to check curing options before a transfer to mass production. The solution is commonly used in R&D departments, universities and lacquer or coating suppliers. The portable lights are available in different sizes and exposure windows. Variations like 50 x 40 mm, 50 x 60 mm or 50 x 80 mm with LED’s of different wavelengths (365 and 420 nm) are available. The light power differs from 250 mW/cm2 (365 nm) to > 500 mW/cm2 (420nm).

Inspection light

For the inspection of rail road’s 4PICO developed a LED solution with white LED’s. Connected to a special carriage these high intensity LEDs illuminates the tracks so that these can be inspected with a CCTV.
