Product Description
The main component of a COB LED lighting system would obviously be the lights themselves. The term COB stands for “Chip On Board”,
and refers to the fact that each unit is actually several LED (Light Emitting Diode) chips mounted together on the same substrate,
which is often ceramic or metal. LEDs are semiconductors that produce photons of light when electrons flow across a junction and
fill “electron holes” on the other side.
COB manufacturers release data sheets for their products that dictate each unit’s specifications, as well as minimum, typical, and
maximum values for a number of different variables. A sample of Cree’s data sheet for the CXB3590 can be found here. A few
examples of a COB’s characteristics that can be found in the data sheet include:
* Color temperature (how “warm” or “cool” is the color of the light?)
* Typical forward voltage (what will the voltage be across the COB at a certain level of current?)
* Maximum current (how many amps of current can you drive the LED with before it dies?)
* Temperature (how does the maximum current rating change, based on the temperature of the COB case?)
* Luminous Flux (how bright is the light when measured at a given current and temperature?)
* Relative Spectral Distribution (what wavelengths of light are most concentrated in the light produced by the COB? Does it peak
in the blue range or red range?)
