Chip-on-board (COB) LED arrays represent a cost-effective route to deliver performance, colour quality and reliability to an LED based lighting product.

As a designated Cree Solutions Provider, offering an integrated design and manufacturing service, Forge can help lighting OEMs to successfully apply both the ceramic-based CXA/CXB and the metal-based CMA/CMT chip-on-board LED technology; maximising the performance gains available from these exciting product platforms, including the latest XLamp^® eTone^™ LEDs - offing 90-CRI colour at the same efficacy at today's 80-CRI LEDs.

High-Density Integrated Arrays	Small (<14mm LES) Standard- Density Integrated Arrays	Large (>14mm LES) Standard- Density Integrated Arrays
high-intensity spotlights, track lights and PAR replacement lamps replacement of ceramic-metal-halide light sources high-lumen applications that could not be addressed by previous LED technologies	directional LED retrofit lamps directional luminaires, including spot and track lighting non-directional luminaires, including downlights applications that traditionally use incandescent, halogen and CFL	directional luminaires, including flood and high output track lighting non-directional luminaires, including downlights mid- and high-bay lighting applications that traditionally use ceramic and pulse-start metal halide

Chip-on-board (COB) LED arrays have become an established and increasingly adopted method of applying LED technology in a diverse range of lighting applications.

Cree COB LED arrays comprise LED chips that are pre-mounted onto a thermally-efficient substrate and encapsulated beneath a layer of phosphor to create a light-emitting surface (LES). This packaging method, complete with on-board solder pads, makes COB LED arrays deceptively easy to assemble, however, in common with all other LED technology it is important not to overlook the consideration of a wide range of design principles necessary to achieve an efficient, reliable and truly cost effective lighting product, notably:

Thermal design
Optical design
Electrical design
Mechanical design

To help our customers all of these areas are considered as part of Forge’s service, and we actively welcome enquiries relating to how successfully integrate chip-on-board LED technology in demanding applications.
