Another category of high power LEDs, chip-on-board (COB) LEDs, also find their footprint in street lighting. A COB LED die-bonds a high density array of LED chips directly to a metal core printed circuit board (MCPCB) or ceramic substrate. The removal of intermediate submounts and direct attachment on a heat sink drastically reduce the length of thermal path, allowing the waste heat to be extracted from the active region of the LED in a very efficient way. The ability to produce thousands of lumens from a single package makes COB LEDs a good candidate for high intensity lighting tasks. The Lambertian output of COB LEDs fits well into applications requiring homogenous illumination over a wide area. However, it requires a very large optical assembly to control beam spread of a COB LED. This makes COB LEDs less desirable in roadway lighting applications where accurate light distribution is important.
