Bluepoint LED eco
The UV curing spot lamp bluepoint LED eco from Hoenle provides high intensity, light curing energy for industrial assembly processes involving UV and visible light curing adhesives, coatings, and sealants. Up to four LED heads can be powered from a single bluepoint LED eco power control unit. The multiple LED heads can be programmed to operate simultaneously, in sequence, or independently. The Hoenle bluepoint LED eco is available with LED wavelengths of 365, 385, and 405nm.
Its incredibly small size (65 x 160 x 130 mm) makes the bluepoint LED eco ideally suited for integration into automated processing equipment. Bench space requirements in expensive cleanrooms can also minimized with the tiny footprint of the bluepoint LED eco. Programming, process monitoring and software downloads can be carried out via the device interface.
A power adjustment feature provides the ability to reduce output intensity from 100% to as low as 10% for maximum operating and adhesive curing efficiency. Process Flow Control permits full programming of the curing cycle including selecting alternating intensities and dwell times for efficient bonding and parts handling.
The bluepoint LED eco requires no warm-up time and provides instant on/off control. Actuation of the LEDs can range from 0.01-9999.0 seconds. Each LED head is equipped with a removable holding fixture for easy mounting. This mounting block also serves as a heatsink for the LED head. UV and Visible light adhesive bonding can be optimized with focusing lenses that adjust light footprint and intensity to create application-specific curing processes. Intensities as high as 20,000 mW/cm2 (405nm) can be achieved.
Optimized curing and high intensity output combine to produce the shortest adhesive curing cycles for your assembly process. Typical applications for the bluepoint LED eco include the curing of UV adhesives, potting materials, and coatings associated with component assembly in the medical, micro-electronics, mobile device, and transportation industries.
In addition, the bluepoint LED eco offers improved machine safety: a special interface ensures that the LEDs are reliably switched off in accordance with applicable safety guidelines – an important protection for operating personnel in automated production lines.

Hoenle has developed new, significantly improved LED heads for the bluepoint LED eco, which remain compatible with existing devices. With a diameter of only 12 mm and a length of approximately 55 mm (depending on the optic, see table), the heads are particularly compact and therefore ideal for tight installation spaces without compromising heat dissipation. They can be optionally equipped with a 90° deflection head to irradiate hard-to-reach areas.
In addition, the LED heads can be combined with various optics that enable irradiation diameters of approx. 3 to 20 mm. A new feature is a 10 × 2 mm line optic that allows homogeneous, linear irradiation for applications such as active alignment.
