COB LED: A Market Growing Like Wildfire

With their notable advantages in lifetime, reliability, and reduced power requirements, LEDs are rapidly moving into mainstream lighting and driving completely new trends of “designing with light”.

While these advantages coupled with fast-reducing costs are a powerful incentive for lamp designers and manufacturers, the actual process of design and fabrication of the light sources involves selection, mounting, and interconnection of discrete devices, adding to the complexity and bill of materials of what was once a simple light bulb in a socket.

Advances in LED chip technologies are enabling the development of a new way to produce solid state lighting- the “COB” (Chip-on-Board) LED Array. At some 40% pa growth, this is the most exciting sector of the LED space.

What is a COB LED?

In these devices a number of bare LED die are mounted directly on a substrate, doing away with the individual packaging for each chip, the need for “binning” or tight selection of color temperature and other optical characteristics, and the need for design, procurement and assembly of interconnecting substrates, thereby greatly simplifying the design and assembly of the fixture or luminaire within which the COB LED Array is used.

The COB LED Market: New & Exciting

COB LED Arrays are becoming the light source of choice in a rapidly expanding range of applications, with growth rates in excess of 40% per year into a potential market which already includes some 40 billion installed sockets. Looking more closely this means that these new light sources will represent the need to mount and interconnect some 35 billion chips per year by the end of the decade. This is a volume and level of activity which doesn’t exist now!!

Graph of COB LED Growth Trends

The COB LED is a new class of lighting product which provides a clearly definable and predictable source of powerful illumination in a compact, readily handled, modular format requiring only two connections to a power source. Direct attachment to an appropriate heat sink helps to manage the balance between light output, reliability, consistent optical behaviour and overall efficacy provided by the Array.

How Can You Get Better Informed About COB LED?

At BPA we are focussing on the fabrication of a COB LED module – examining the opportunities and challenges for the packaging technologies and materials that come together to create this exciting new opportunity.

These materials and processes define mechanical and thermal properties together with optical shaping and color management, providing a physically rugged, totally integrated luminous platform for the final product. The characterization and mounting of the LED chips themselves within the array determine the light intensity along with some of the color management required for the application.

The result are fast-growing opportunities for substrates, board level interconnect, die attach, die bonding, encapsulation and thermal and optical management.
