Chip-on-Board LED Technology

Chip-on-Board LED technology describes the mounting of a bare LED chip in direct contact with the substrate to produce LED arrays. It is a method of LED packaging which has a number of advantages over traditional surface mount technologies such as the use of “T-pack” and Surface mount LEDs.

Due to the small size of the LED chip, Chip-on-Board technology allows for a much higher packing density than surface mount technology. This results in higher intensity & greater uniformity for the user.

The figure below illustrates the differences in the number of LEDs that can be placed on a 10X10mm square and the resulting power output of the array.



As you can see, by using COB technology, the number of LEDs is 38 times higher than T-Pack technology and 8.5 times higher than surface mount technology, improving the brightness significantly.

ProPhotonix employs Chip-on-Board technology in its entire range of Specbright solutions, COBRA series solutions and in its LOTUS line light. In addition, we work with customers in diverse industries to design and produce custom chip-on-board LED solutions from LED arrays to complete turnkey solutions.

The advantages of Chip-on-Board LED arrays include:
  • Compactness due to small size of chip
  • High-Intensity, particularly at close distance
  • High-Uniformity, even at close working distances
  • Superior Thermal Performance for better lifetime, stability and reliability
