Volpi is introducing the intraLED 3 LED light source. This economical and compact lighting system has a service life of 50,000 hours and a light intensity of over 500 lumens (measured on a 1-meter light guide with an active diameter of 13.5 mm).

The success of an image processing application depends to a large extent on the quality of the lighting system selected. The most important factors for success are having both a luminous flux that is as high as possible and very good homogeneity values. To comprehensively meet these requirements Volpi is introducing the intraLED 3 LED light source.

The intraLED 3 LED light source is the next generation model of the successful IntraLED 2020. When developing the new high-power light source, the Volpi engineers were strictly focused on the requirements of machine vision. With a light intensity of over 500 lumens (measured on a 1-meter light guide with an active diameter of 13.5 mm), a performance increase of more than 30% was achieved over the previous model. According to the manufacturer, the light homogeneity is +/- 5% and the typical color temperature is 6000 degrees Kelvin. Activation is done either manually via the integrated RS-232 interface (optional USB) or via the multiport with digital and analog input. The intraLED 3 is available in two variants and is thus compatible with light guides from Volpi and Schott-Fostec.

Given these specifications, most applications with 100 watt or 150 watt halogen light sources can now be implemented with an intraLED 3. Replacement of conventional halogen light sources offers the user numerous advantages: the long service life of 50,000 hours, the maintenance-free design and the substantially lower power consumption (24 V DC / max. 55 W) noticeably reduce total operating costs. The compact enclosure allows use on a small surface and the threaded rails (M4) present on 4 sides facilitate smooth system integration. Due to its low heat emission, in critical applications the ambient temperature no longer has to be cooled, or cooled as much as previously. This gives indirect power savings and a further reduction of the company's CO2 footprint.

Compared to pure LED lighting components such as long LED line illuminations, the hybrid approach with LED light sources and homogeneous fiber-optic line illuminations offers cost advantages and more flexibility in the application. With meters-long LED line illuminations, as a rule the entire system has to be dismantled if individual LED modules fail. By contrast, hybrid systems allow replacement of individual light sources in the blink of an eye and the risk of stoppage due to time-intensive maintenance work is substantially lower. Another advantage of a hybrid solution is higher flexibility. With easy-to-replace glass fiber components the lighting situation can be flexibly switched between bright field, dark field and transmitted light.
