New LED Lamp from DELO Speeds Up Adhesive Curing

Oct. 19, 2020
The DELOLUX 504 offers triple the intensity of its predecessor.

Technical Highlights

  • Maximum intensity of 4,000 mW/cm²
  • Wavelength of 365 nm
  • Typical working distance between 6 and 15 mm
  • Typical irradiated area is 3 mm x 8 mm
  • Lamp head dimensions are 42 mm x 20 mm x 7.3 mm

Sudbury, MA October 2020 – DELO, one of the world’s leading manufacturers of industrial adhesives for automotive, consumer and industrial electronics applications, now offers an LED lamp for curing UV adhesives. The DELOLUX 504, a spotlight lamp, features the latest generation of UV LEDs, achieving three times the intensity of the previous model.

This new LED lamp was developed for high-speed production in the electronics and automotive industries that require small areas to be irradiated and equipment to be easily integrated into existing systems.

A lamp with dual benefits

DELOLUX 504 has a maximum intensity of 4,000 mW/cm² at a wavelength of 365 nm, providing double the benefit to its user. The lamp’s higher intensity makes UV adhesives cure faster, reducing cycle times. In addition, the lamp can be placed farther away from the adhesive it is curing. Since the high intensity compensates for the physically induced power reduction that occurs with increasing distance, the lamp is able to provide more flexibility for integration into production lines. The typical working distance range is between 6 and 15 mm.

Well-designed lamp

With a lamp head measuring 42 mm x 20 mm x 7.3 mm, the compact DELOLUX 504 is excellent for use in tight installation configurations.

The lamp offers optimized thermal management, ensuring that the heat generated by the LEDs is quickly dissipated by a direct connection to the heat sink. This increases the lifetime of the LEDs. The lamp’s passive cooling allows it to be used in clean rooms. The elliptical light exit area makes it possible to selectively irradiate only certain areas. A typical irradiated area is 3 mm x 8 mm.

Fixing points, geometry of the emitted light, as well as light distribution characteristics of the DELOLUX 504 spotlight source are the same as those of its predecessor the DELOLUX 502. Existing systems can therefore be converted with very little effort.

In contrast with other lamp systems on the market, the DELOLUX 504 has a separable connecting cable so that the lamp head can be easily replaced without having to disassemble an entire production line.
