FDC-LED: Full Dissipated LED Chip

The latest FDC-LED technology ensures complete heat dissipation in every direction.
The multiple LED chips are connected to each other to form a single unit and incorporated completely in heat dissipating material.
The classic double soldering of the classic SMD led (chip on metal and metal on printed circuit board) is replaced by direct soldering of the chip on the printed circuit board, thus eliminating a thermal bridge.
Moreover, all the chip is drowned in a transparent conductive gel of generous size that allows a good heat dissipation even on the illuminated side, unlike the classic LED with small plastic cap.
The LEDs have a higher light output because a better thermal dispersion is guaranteed.
In addition, a great uniformity of illumination is obtained due to the total coverage of phosphorus over the entire module, the presence of the single light chip is difficult to recognize.
Lowering the temperature of the LED junction extends the life of the component.

Examples of industrial or special applications

HCL-LEL-C linear illuminator that projects a focused beam to generate controlled shadows for 3D analysis.

Square-mounted HCL-LEL-C linear illuminators for detecting defects such as scratches and dents on the surface of aluminium objects.

VEA's linear illuminators for machine vision systems are specifically designed to generate controlled illumination. These illuminators have allyl diglycol carbonate monomer focusing lenses that ensure a coherent beam with low distortion. By placing multiple HCL-LEL illuminators in different positions and turning them on in sequence, vision systems significantly improve part inspection and ensure reliable defect detection.
