Understanding The COB LED Array Opportunity And What It Means For Your Business

The ‘single hot, bright source’ model which has dominated lighting since our remote ancestors huddled around campfires is giving way to a completely new way of designing and illuminating with light.

Dramatic improvements in efficiency and color output of LEDs are leading not only to many new ways of using light, but also in the way these revolutionary sources are packaged.

One of the most significant emerging trends is the use of Chip-on-Board packaging technology to create LED Arrays.

This new class of lighting product provides a clearly definable and predictable source of illumination in a compact, readily handled, modular format that requires only two connections (visible in the photo) 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.

Targeted phosphors are included in lensing – either as an encapsulation for the chips or an off-mounted phosphor lens – to create the desired color mix and beam development.

The low voltage, low power requirements of COB LED Arrays along with their small size and steadily improving light output per watt present a new way of designing with light. They eliminate the technical and commercial complexities associated with individually packaged LEDs: “binning” or output matching of individual devices, the volume and thermal resistance of the packages themselves, and the need for an interconnecting substrate- greatly simplifying the design, bill of materials, and manufacturing of lighting in a vast range of general and specialty lighting applications.

As a result a new range of users, more familiar with design than electronics, is emerging to exploit the game changing array of lighting possibilities that the LED world provides. The simplicity and elegance of the COB LED solution are driving growth rates in excess of 40% per annum for:
