High-intensity, air-cooled, VCubed line lights for linescan applications


As line-scan speed increases, the illumination also needs to increase in intensity to enable high quality image acquisition and the VLX range of LED lights is designed specifically to meet this need. With light intensity orders of magnitude higher than conventional LED line light technology, the VLX lights provide an extremely powerful, focussed line-of-light at the subject.

More efficient than Fibre Optic Lights
Historically, applications requiring a high intensity line light source employed fibre optic solutions due to the light's narrow profile. The VLX lights have been designed with a narrow form factor, providing a high-intensity, solid-state lighting solution for these applications

Heat and lights
With any LED light, the fundamental failure mechanism is heat; the LEDs become hot and the lifetime of the LED degrades. Thermal management of LEDs is critical for long life time performance. The VLX range of lights are designed to ensure maximum cooling and thermal stability of the LEDs. The VLX range offers both air and water cooling depending on the model chosen. They have an internal temperature limit and will automatically shutdown should the temperature exceed the limit. In the unlikely event that an LED fails, this can also be diagnosed via the serial interface. All settings are stored in non volatile memory.

VLX1 - High-brightness LED Line lights: Ideal for high-speed/high resolution

Gardasoft VCubed VLX1 air-cooled linelights give very bright, uniform lighting focussed to a narrow beam.

The VLX1 overcomes the limitations of many linescan systems by employing an air-cooling system to give very bright, uniform lighting focussed to a narrow beam. Using the high brightness VLX1 lighting line scan cameras can run faster for higher production speeds and/or higher resolution images.

Providing a better alternative to Fibre optic light sources, the VLX1 does not have costly bulbs to change, saving costs and reducing process down-time. The VLX1 LED lights also offer a more stable colour over time and temperature than conventional filament or discharge lights.

Greater reliability, efficiency and consistent operation are enhanced by the VLX1 which manages heat with very low thermal resistance path bonding of its LEDs to the heatsink. It also offers a forced-air version for even more effective cooling.

An RS232 communications interface is provided to allow full control of the VLX1 and make measured status information available. The light output from the units can be varied over a very wide range and is either preset or controlled via a communication interface. System temperature and individual LED failure detection can be monitored.

Typical applications for the VLX1 include:
** Web inspection
** Surface inspection
**
Pharmaceutical quality control
**
PCB and assembly inspection
**
Film/foil inspection
**
Rail/road inspection
**
Food industry
